• »Device for processing plastic pipes ¹¹

The utility model concerns one door direction for processing plastic pipes »« rich aich due to their simple construction and versatility, both as well as beveling the pipe ends of plastic pipes as well as for expanding them excels.

In the art of uniting often earlier it was necessary to attach an outer boBw from the tape to the pipe ends. make inner cutting of the wall in order to be able to plug one drill into the other for the purpose of uniting the same. Here it is necessary that the outer end of the pipe is heated up and, after the pipe has cooled, one can be pushed into the other, whereupon the two files are cemented together.

It was also necessary when assembling Plastic pipes to the socket of dial gauges and other metallic bodies and transition pieces the ends of the Kunetatoffrohre after heating duroh Widening the pressing in of conical bodies by hand, thus pushing the saiden of the plastic pipe it is possible on the metallic pipe connector was

This work to be carried out when machining plastic pipes had previously not been carried out by anyone "which was quite laborious and time-consuming. Also was widening the dae-piercing with bieherlgen primitive means rather inaccurate because the _f Aufweitungödurchmösser for the individual plastic pipes from case to case changes *

The deficiencies described above are caused by the device according to the utility model. on the side that the same from an aohraubetockverbindungen Clamping device for the plastic pipe to be processed and a pre-spindle which is arranged at right angles to the clamping jaws and which holds the machining tool exists, which is operated by means of a crank.

The clamping jaws advantageously exist Screw hooks made of rubber or another suitable one

material

Material or plastic to avoid any damage to the to prevent plastic pipe to be clamped.

According to the invention, a milling tool is used for the purpose of making millings on the plastic pipe ends can be placed on the milling spindle, which consists of knives standing on edge, the are united to a cone or a pyramid » whereby the milling tool for several Eohrdurahmeseer is usable.

After this. Utility model is used for the purpose of expansion warmed plastic st off pipe ends one instead of the Milling spindle in the clamping device one et abare expansion spindle »on which one under the pressure a conical, axially displaceable expanding mandrel standing upright in leather sits »which is inserted into the pipe end of the Kuttststoffrohres can be pressed.

The widening spindle 14 is used "Both the work spindle 3 and the widening spindle 14 are set in rotation by the hand crank 4, when the milling tool 7, 8 and the other time the expanding spindles 14 are actuated with the expanding dome 16. The clamping brackets 2 consist of vices rubber or other suitable material, for example plastic, to each damaging prevent the to be clamped plastic pipe & ssxk * purposes attaching Anfrästtngen at the ends of KunotBtoffrohre let a milling tool 7.8 on the milling spindle 3 aufeet2bar, which consists of upright aufeinender standing Umaern 7, which are united in a cone or a! »yraiaide» You number aetv knife is arbitrary.

or are interchangeably built in. The conical shape of the milling cutter allows _{t use the} same for all common tubular diameters.

The conical or pyramid-shaped cutting tool 7, 6 can be inserted with its knives 7 into corresponding slots 10 of a milling insert 9 which is open on the milling spindle 3 and which sits as a bait for the spindle 5. Bs Can be inserted with its tip or with its lower, open bath in the milling unit 9, in which it is through. "In the working position shown in Hg. 1 and 2, the milling tool is held with its tip in the Eeäs insert 9" In this position it is suitable for making an external milling on the plastic tube 6 When inserting the milling tool in the opposite direction in ^ em Pree insert 9, as illustrated by ate Pig, 5 and β, is attached to the inner wall of the plastic tube 6 duron the conical or pyramidal milling tool, the bevel.

According to another embodiment of the device according to the invention can in the holding device 1 instead of the milling spindle 3 an expanding spindle 14 can be used, on which a lower The conical, axially displaceable expanding mandrel 16 standing under the pressure of a spring 15 is shown in FIG the pipe end 13 * of a plastic pipe 13 can be imprinted istι to widen it · 0for this purpose the heated plastic pipe 15 is placed in the clamping jaws 2 of the vice clamped. But in order to prevent the plastic pipe 15 from being pressed flat, a passport cover 19 engages in the hollow bore, welohee sits on the expansion spindle 14 · Daa adapter 1 $ depends in its size on the diameter of the pipe to be expanded * For everyone Pipe diameter of the usual drilling sizes is a A corresponding adapter is provided, which can be placed on the free bath of the expanding spindle 14 as desired and is held by a screw 20 or a split pin * Bl * expansion spindle 14

The threaded bushing X8 is mounted in the bearing sleeve 21 the device 1 clamped. The end of the genus 17 on the wide spindle carries the crank 4, öo that through Turn the crank, the expansion spindle 14 with the expansion dome 16 is set in rotation. the latter pushes against the bridge; the spring 15 into the Plastic pipe 13 * on · The latter by heating is soft, the constant pressure of the expansion dome causes 16 and the rotation of the same an expansion of the hearing end, which quickly and easily on the desired diameter can be brought · As soon as the pipe has the sufficient width »the whole thing left to cool, so that the pipe has this diameter maintains.

The way of working awecks milling out the ends of plastic pipes respectively. the application of millings to the art and often ends early and the widening of the plastic pipes to any predetermined durometer is possible with the device according to the utility model in a simple manner in a short time "so that the installation pays for itself very quickly" the ever increasing use of Kunatstoffrohren for multiple purposes, in particular in construction technology, forcing tined to find appropriate means to know edit rationally to such Drill · This will allow the device according to the invention "
