Description

The invention relates to a machine for crimping cable wire ends with wire end sleeves or the like. Connection elements according to the preamble of claim 1.

The object of the invention is to further develop such a machine, in particular to simplify it considerably.

This object is achieved by the teaching according to the characterizing part of claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

When moving the slide according to the invention, the next following, currently stationary wire end sleeve, the plastic collar of which projects above the slide, reaches with its metallic tube piece in the preferably elongated, narrower section of the keyhole-like first opening in the upper finger of the moved slide, so that it is at the end of the Moving when the opening in the web of the slide guide is flush with the second opening in the lower finger of the slide, cannot fall through simultaneously with the wire end sleeve already present in the opening of the web of the slide guide, but only when the slide is moved back into the rest position falls into the web opening (since the wire end sleeve previously present there has failed), but hits the closed surface of the lower finger with the lower end of the metallic tube piece; however, another wire end sleeve can now move up (see also FIGS. 23, 24 with FIGS. 25, 26).

In contrast, only a device for pressing (not shown) «sleeves» onto the end of a wire or a strand has become known (cf. DE-A-32 05 413).

• - wobei die Zentriereinrichtung insbesondere mit ihrem stumpfkegeligen Abschnitt ein sicheres Einführen des Litzenendes in abisoliertem Zustand auch dann sicherstellen soll, wenn einzelne Litzendrähte von der Längsachse des Litzenendes seitlich abstehen.

While in this known embodiment the feed of the “sleeves” to the centering device and to the pinching device and the structure of the stripping device are left completely open, only the following structure is disclosed for the centering device and the pinching device (both in the claims and in the description of the frame):

• - The movable, the "sleeve" receiving squeeze chamber can be reduced in cross-section to compress the "sleeve" by
• - four segment bodies having the shape of straight prisms, the
• are arranged around the square squeeze chamber such that a side face of each segment body forms a side wall of the squeeze chamber, and
• - Are each slidably guided along a straight line in a cross-sectional plane perpendicular to the longitudinal axis of the segment bodies; and
• - The centering device for inserting the end of the wire or the strand into the sleeve located in the squeezing chamber accordingly has:
• - In front of the squeezing chamber four segment bodies having the shape of straight prisms in the direction of insertion of the wire or the strand, the
• - Are arranged around the centering chamber so that a side surface of each segment body forms a side wall of the centering chamber, and
• - Are each guided along a straight line in a cross-sectional plane perpendicular to the longitudinal axis of the segment bodies, and

• - The centering device, in particular with its truncated cone section, should also ensure a secure insertion of the stranded end in the stripped state when individual stranded wires project laterally from the longitudinal axis of the stranded end.

• - Absioliereinrichtung :
  • zwei Messer und ein Anschlag, mit dem die Schnittiefe genau eingestellt werden soll, damit beim Abisolieren die Litze nicht beschädigt wird ;
• - Hülsen-Zuführeinrichtung :
  • über ein auf einer Magazinscheibe aufgewickeltes « Hülsen-Band » (Hülsengurt) automatische Zufuhr der Aderendhülsen zu einem Einführtrichter ;
• - Aufpresseinrichtung :
  • eine Vierkantverpressung soll durch einen Kniehebel und konstanten Federdruck ein konstantes Quetschergebnis erzielen ;
• - Bewegungssteuerung :
  • Getriebe mit Magnetkupplung und -bremse sowie mit « gehärteten Kurven ».
  • Nachteile dieses bekannten Stands der Technik sind insbesondere :
• - unvermeidliches aufwendiges Gurten der Aderendhülsen,
• - was die dort angestrebte Zeiteinsparung durch das automatische Abisolieren erheblich in Frage stellt wegen der dort erforderlichen Handarbeit (die dem zu vermeidenden « mühseligen Einfädeln der Aderendhülse » in nichts nachstehen dürfte),
• - ganz abgesehen von der zusätzlichen Beschaffung von Gurtmaterial, das zudem als Abfall übrig bleibt,
• - schließlich auch die Lagerhaltung erschwert und
• - wegen der beträchtlichen Abmessungen der Hülsengurt-Magazinscheibe die gesamte Vorrichtung beträchtlich sperriger macht;
• - gesonderte, aufwendige Zentriereinrichtung für ein sicheres Einführen des abisolierten Litzenendes ;
• - aufwendiger, störanfälliger Aufbau der Quetscheinrichtung insbesondere wegen der zahlreichen Segmentkörper und deren Lagerung ;
• - gesonderter Auswerfer (der Quetscheinrichtung), der Aufwand und Störanfälligkeit der gesamten Vorrichtung erhöht ;
• - nicht bestriebssichere und relativ langsam ansprechende Steuerung in Form der « gehärteten Kurven » ;
• - schwierige, allenfalls sehr begrenzte oder überhaupt unmögliche Einstellbarkeit der Vorrichtung auf unterschiedliche Hülsen-Abmessungen ;
  • so ist der « Klemmfix 2001 » lediglich für einen ganz bestimmten Draht (1,5 mm NYAF) und eine ganz bestimmte Endhülse (1,5 mm x 10 mm DIN 46 218) vorgesehen, was einen Einsatz in der betrieblichen Praxis sehr einschränkt ;
• - keine konstante Aufquetschqualität wegen des Kniehebel-Feder-Antriebs der Quetscheinrichtung und damit möglicher Alterung der Feder.

In this context, a «automatic end-sleeve placement machine for (exclusively) 1.5 mm x 10 mm end sleeve DIN 46 218 on 1.5 mm NYAF wire with the following features has become known (company name« Klemmfix 2001 »from the company Weiszhar):

• - stripping device:
  • two knives and a stop with which the depth of cut should be set precisely so the wire is not damaged when stripping;
• - Sleeve feed device:
  • via a «sleeve tape» (sleeve belt) wound on a magazine disc, the ferrules are automatically fed to an insertion funnel;
• - Press-on device:
  • a square crimp should achieve a constant squeezing result by means of a toggle lever and constant spring pressure;
• - motion control:
  • Gearbox with magnetic clutch and brake as well as «hardened curves».
  • Disadvantages of this known prior art are in particular:
• - unavoidable expensive strapping of the ferrules,
• - Which considerably jeopardizes the time saved by automatic stripping due to the manual work required there (which should in no way be inferior to the «tedious threading of the ferrule» to be avoided),
• - not to mention the additional procurement of belt material that also remains as waste,
• - Finally, it also makes storage difficult and
• - Because of the considerable dimensions of the sleeve belt magazine disc, the entire device is considerably bulky;
• - Separate, complex centering device for safe insertion of the stripped wire end;
• - Complex, fault-prone structure of the pinch device, in particular because of the numerous segment bodies and their storage;
• - Separate ejector (the squeeze device), the effort and susceptibility to failure of the entire device increases;
• - control that is not reliable and responds relatively slowly in the form of the “hardened curves”;
• - Difficult, at most very limited or impossible to adjust the device to different sleeve dimensions;
  • For example, the "Klemmfix 2001" is only intended for a very specific wire (1.5 mm NYAF) and a very specific end sleeve (1.5 mm x 10 mm DIN 46 218), which limits its use in operational practice;
• - No constant squeezing quality due to the toggle spring drive of the squeeze device and thus possible aging of the spring.

In addition, numerous machines for crimping cable wire ends with previously specially taped crimp contact elements, which therefore have to be fed and processed in a belt-like manner, have long been known (cf., for example, US Pat. No. 3,376,627).

When the swivel-push frame 30 is steered into the other end-push position, this swivel position change of the jaws 102, 103, 105 is repeated (from FIG. 20 back to FIG. 19).

• - End sleeve feed device 200:
  • It feeds the crimping / fitting device 100 and, according to marg. 2 and 21, has a wire end sleeve storage container 201 arranged outside the housing 10 in the form of an oscillating conveyor (not shown in more detail), one the wire end sleeves A from this one behind the other in the vertical axis direction and with the metallic pipe section a receiving vertical ferrule feed shaft 202, which is inserted from above into the housing 10 between its front wall 11 and the front plate 31 of the swivel-slide frame 30, and a ferrule singling device 203 controlling the ferrule feed shaft 202, which feeds a single ferrule A to the crimping / fitting device 100 when actuated.
• - End sleeve separating device 203:
  • According to marg. 21-29 it has a U-slide 204, which according to in particular FIG. 29 has two fingers 205 and 206, which are spaced one above the other in the ferrule feed shaft 202, and is guided in a slide guide in the form of a slide housing 207 which has a guide recess 208 corresponding to its cross section. One of the slide fingers 205 and 206 is located in a housing web 209 which extends over the length of the guide recess 208 and over which the slide 204 extends with its fingers 205 and 206 limited bore 210 of (slightly) more than ferrule length provided, which together with two tubes 211 and 212, one from above to the upper finger 205 and the other from below to the lower finger 206 in the Slider housing 207 is inserted, the ferrule feed shaft 202 forms.

For additional guidance of the slide 204 in the slide housing 207, two stud bolts 213, which are inserted into the slide housing 207, are provided, which are incorporated in the direction of movement of the slide 204 in guide bores 215 provided in the base body 214 of the slide 204. The slide 204 is held in an end position by two prestressed compression coil springs 216 which are supported on it and on the slide housing 207 and which are penetrated by the stud bolts 213 and which is limited by a stop plate 217 screwed to the slide housing 207.

28, 29, in particular, the upper slide finger 205 has a bore 218 corresponding to the light passage of the ferrule feed shaft 202 and a slot 219 extending towards the stop plate 217 and slightly larger than the diameter of the metallic tube piece a of the ferrule A. , both of which (218 and 219) widen towards the upper section of the ferrule feed shaft 202 formed by the tube 211 and together form a keyhole profile.

28, 29, in contrast, the lower slide finger 206 only has a bore 220 corresponding to the light passage of the ferrule feed shaft 202. The bore 218 in the upper finger 205 and the bore 220 in the lower finger 206 are offset from one another in such a way that in the end position of the slide 204 delimited by the stop plate 217, the bore 217 in the upper finger 205 covers the feed shaft 202 and the bore 220 in the lower finger 206 is displaced from the area of the ferrule feed shaft 202.

As a result, a wire end sleeve A can form from the tube 211 inserted from above up to the upper slide finger 205 into the slide housing 207, which, as the upper section of the wire end sleeve feed shaft 202, forms a wire end sleeve magazine, in the section formed by the slide housing bore 210 of the wire end ferrule feed chute 202. The wire end sleeve which has moved upward from the stored wire end sleeve from the wire end sleeve magazine and which is embedded with a partial length of the metallic tube piece a on the plastic collar b of the stored wire end sleeve A, projects with the metallic tube piece a into the slide housing bore 210 (FIGS. 25, 26 ).

If the slide 204 is then moved against the force of the compression coil spring 216 from the end position delimited by the stop plate 217 to the other end position, the bore 220 in the lower slide finger 206 with the ferrule feed shaft 202 comes in and the bore 218 in the upper slide finger 205 out of register with the ferrule feed shaft 202, wherein the slot 219 extending from the bore 218 in the upper slide finger 205 crosses the ferrule feed shaft 202. As a result, the wire end sleeve stored in the slider housing bore 210 is released into the tube 212 forming the section of the wire end sleeve feed shaft 202 for loading the crimping / fitting device 100, and the next wire end sleeve protruding into the slider housing bore 210 with the metallic tube piece a is released access to the slide housing bore 210 is blocked by the upper slide finger 205.

2, the ferrule feed shaft 202 is arranged in such a way that when the pivot-push frame 30 is pivoted into the first end pivoting position and moved into the first end-pushing position, its opening near the ferrule-receiving mouth 126 of the crimping / fitting Device 100 is positioned (FIG. 11).

The actuation of the ferrule separating device 203 for loading the crimping / fitting device 100 with one ferrule A each is carried out by a bolt 227 (FIG. 2) attached to the front plate 31 of the swivel-push frame 30, which in the first end Swiveling position from the second end-push position into the swivel-push frame 30 controlling the first end-push position through a bore 221 in the stop plate 217 of the ferrule separating device 203 and pushing on the slide 204 of the ferrule separating device 203 (FIG. 21, 22, 27).

The tube 211, which forms an end sleeve magazine as the upper section of the end sleeve feed shaft 202, has two receptacles 222 and 223 for one light barrier each, which monitor the minimum and maximum fill level of the end sleeve magazine and, depending on the magazine fill level, the end sleeve reservoir container 201 as a vibratory conveyor - or switch off.

• Er wird anhand insbesondere der Fig. 1, 2 sowie des Betriebsablaufplans gemäß Fig. 30 beschrieben, der den durch Schalter S1-S10 bewirkten automatischen Betriebsablauf der pneumatischen Druckzylinder Z1-Z6 und des Elektromotors 62 vom Start der Maschine bis zu deren erneuter Startbereitschaft im Zusammenhang aufzeigt anhand der aufeinanderfolgenden Betriebsabschnitte T1-T9 vom Start der Maschine bis zu deren erneuter Startbereitschaft. Wegen der Einzelheiten der Betriebsabschnitte T1-T9 wird ausdrücklich auf Fig. 30 verwiesen, um möglichst Wiederholungen im folgenden Text zu vermeiden.

Operation of the first embodiment of the machine:

• It is described in particular with reference to FIGS. 1, 2 and the operating flow chart according to FIG. 30, which relates to the automatic operating sequence of the pneumatic pressure cylinders Z1-Z6 and the electric motor 62 caused by switches S1-S10 from the start of the machine until it is ready to start again shows on the basis of the successive operating sections T1-T9 from the start of the machine until it is ready to start again. Because of the details of the operating sections T1-T9, reference is expressly made to FIG. 30 in order to avoid repetitions in the following text wherever possible.

When the machine is ready to start again after the last operating step T9, the swivel-push frame 30 is in the first end Pivotal position and in the first end-push position, whereby the stripping device 50 is pivoted towards the cable core insertion 20 and is pushed close to the open cable core tensioning device 22 with the cable core guide funnel 64. The crimping / fitting device 100 is positioned (FIG. 11) with the ferrule pliers jaw 126 open at the mouth of the ferrule feed shaft 202 of the ferrule feed device 200, from which it received a ferrule A in the final phase of the last operating step T9 .

Is now provided for crimping with a ferrule A cable wire end KE through the insertion funnel 21 and the controlled cable wire tensioning device 22 of the cable wire insertion 20 and through the guide funnel 64 of the stripping device 50 into the machine so far that it is inserted into the The mouth of the stripping pliers 51 actuated and protruding there actuates a limit switch S1, this in turn triggers the closing actuation of the cable core tensioning device 22 by the cable core tensioning pressure cylinder Z1 and the closing actuation of the stripping pliers 51 by the stripping pressure cylinder to initiate operating step T1 Z2 and the clamping of the wire end sleeve A in the crimping / fitting device 100 by the wire end sleeve clamping / return pressure cylinder Z5.

After the end of the operating step T1, to initiate the operating step T2, an end switch S2 which detects the piston position of the pressure cylinder Z5 triggers the actuation of the swivel-push frame 30 into the second end-push position by the push-pressure cylinder Z3 and, on the other hand, delays it somewhat Electric motor 62 turned on, the pinion 63 and the ring gear 61, the pipe slide 56 and thus the insulating jacket of the cable core K in their closed position up to their metal wire core with the cutting plates 52 notching stripping pliers 51 rotating for a few revolutions, which simultaneously by the Control of the swivel-push frame 30 is advanced in the second end push position, so that an insulating jacket piece of the cable core end KE is cut off and then pulled off, the cutting plates 52 executing a spiral movement along the metal wire core and thereby additionally twisting them, so that a spreading of her what the Aufb ring ferrule would complicate or even prevent is excluded.

As soon as the swivel-push frame 30 is pushed into the second end-push position after the operating step T2 has ended and the stripped cable wire end KE is released by the guide funnel 64 of the stripping device 50 and the runtime-controlled electric motor 62 is also switched off, the operation step is initiated T3 by means of an end switch S3 which detects the second end-push position of the swivel-push frame 30 on the rear plate 32 thereof, the control of the swivel-push frame 30 into the second end-swivel position by the swivel pressure cylinder Z4 and the opening of the stripped wire -Tongs 51 triggered by the stripping pressure cylinder Z2.

As soon as the swivel-push frame 30 is turned into the second end swivel position after the operating step T3 has ended and the crimping / fitting device 100 is swiveled towards the koad wire insertion 20, the second end is initiated by a Swivel position of the swivel-push frame 30 at its lever 39-detecting end switch S4 (Fig. 2) triggered the displacement of the swivel-push frame 30 into the first end-push position by the push-pressure cylinder Z3, whereby the in the squeeze / Fitting device 100 clamped wire end sleeve A is positioned on the stripped cable core end KE.

As soon as after the end of the operating step T4, the wire end sleeve A is applied to the stripped cable wire end KE, the pushing on of the wire end sleeve is carried out by initiating the operating step T5 by means of an end switch S5 which detects the first end push position of the swivel-push frame 30 on its rear plate 32 A triggered on the stripped cable core end KE by the squeeze pressure cylinder Z6.

As soon as the pressure in the squeeze pressure cylinder Z6 has reached the value required for squeezing the metallic tube piece a of the wire end sleeve A through the squeeze jaws 102, 103, the reversal control of the pressure cylinders Z5 and Z6 is triggered by a pressure-controlled switch S6 which detects it and thus releases the crimped-on ferrule from the ferrule pliers 101 in the crimping / fitting device 100.

After the end of the operating step T6, to initiate the operating step T7, the control of the swivel-push frame 30 is activated by an end switch S7 which detects the release of the crimped-on wire end sleeve from the clamping in the crimping / fitting device 100 on the wire end sleeve clamping / return pressure cylinder Z5 in the second end-thrust position by the thrust-pressure cylinder Z3 and by actuating the end switches S3 or S8, the opening of the kettle core tensioning device 22 to be detected by a switch S8 (e.g. a light barrier) (FIG. 1) completely pulling out the fitted cable core end KE triggered by the cable core tensioning pressure cylinder ZI, which actuates a limit switch S10 (FIG. 1).

The end switch S3 which detects the second end-push position of the swivel-push frame 30 then triggers the piston retraction of the swivel pressure cylinder Z4 and thus swivels the swivel-push frame 30 back into the first end-swivel position.

Finally, after operation T8 has ended, operation T9 is initiated by a limit switch S9 detecting the first end pivot position of the pivot-push frame 30, the piston extension of the push-pressure cylinder Z3 is triggered, which pushes the pivot-push frame 30 back into the first end-push position, so that the machine for one restart is ready.
