Definitions

  • the invention relates to a Linearwegschieber according to the preamble of claim 1.
  • Linear path slider of the type mentioned are used as actuators in various facilities for the processing and processing of metallic materials and plastic or plastic composite materials.
  • the tasks of these assemblies typically include pressing, forming, embossing, bending, crimping, punching, cutting, joining, joining presses and the execution of delivery functions with special requirements.
  • the properties of the Linearwegschieber special requirements are made, including in particular a very high energy density, a very high guidance accuracy and a very high stiffness against shear forces and against rotation. Furthermore, they should have the most compact design possible and allow a standardized basic assembly a flexible, universal use. Furthermore, properties such as maintenance-free life, a robust construction for use in polluted environments, the possibility of any installation position, absolute tightness (e.g., overhead installation), and last but not least, low cost manufacturing are desirable.
  • Linear Wegschieber are known in various embodiments. Due to the required high energy density, it is preferably hydraulic devices. Basically, however, the concept of a pneumatically operated device is possible.
  • CH-A-604021 shows a known Linearwegschieber with the features of the preamble of notes 1, which is provided for performing rectilinear reciprocating movements with a respect to the housing rotationally fixed piston rod from a cylindrical tube and two within the cylindrical tube arranged at the ends Guide bushes and a guide piece attached to the cylindrical tube consists.

  • This is a Linearwegschieber to be created, which has a rotationally secure in the radial direction of the piston rod, which is loaded by high tensile and compressive forces and can absorb high buckling stresses, and in which the pressure medium prevent the leaking sealing elements are largely protected from injury.
  • DE-A-32 41 233 describes a drive unit for pressure medium drives, should remain largely unchanged in the guide accuracy, sealing and performance even after prolonged operation.
  • this drive unit with a surrounding the pressure fluid cylinder cladding tube, which is secured to the piston rod and slidably held in a direction extending in the frame guide, can meet these requirements, on the outer surface and the inner surface of the cladding separate intermediate links of low-friction lubricant for lateral support the pressure medium cylinder provided on the frame-fixed guide.
  • the sliding properties are to be improved on both surfaces of the cladding tube, so that the support can be made more direct and accurate.
  • a fluid-actuated feed unit is described in DE-A-5,609,091, which should have a compact design with precise guidance and simultaneous rotation of the feed part.
  • This is achieved in that the feed part is formed at least along its guided in the housing length portion as a three-sided prismatic body, which is guided in the region of its three side surfaces in the housing, while the three transition areas are circulated between each two adjacent side surfaces. Due to this shape of the guided length portion of the feed part an extremely resilient rotation is to be achieved.

  • Combinations of commercially available linear cylinders are particularly well-known as compact built-in modules, which are formed with rigid linear guide units by "saddling on” or by forming a constructional longitudinal combination.
  • hydraulic block cylinders are known, the housing having additional holes for guide rods, which are arranged parallel to the actual hydraulic cylinder.
  • the piston rod head and one to usually a maximum of four guide rods are bolted together in a rigid top plate. This arrangement ensures flexural rigidity and security against twisting.

  • the slider housing has an opening on its upper longitudinal side.
  • the hydraulic oil connections are also located on this mounting flange. It is both a lateral as well as an upward connection with appropriate guidance of the pipes possible to meet different, cramped installation conditions.
  • the Linearwegschieber described is characterized by its high-load capability and the precise sliding of the prismatic slide. Its use, however, is limited in some cases by the size and weight. Furthermore, a repair of Linearwegschiebers is relatively expensive.
  • the invention has for its object to achieve a more compact design with a reduced volume and a reduced weight at a Linearwegschieber of the type mentioned. At the same time the Linearwegschieber easier to repair and be flexible in its applicability. Last but not least, the production costs should also be reduced.
  • the Linearwegschieber invention is formed in such a way that the cylinder and the working space are arranged in the slide, that the piston is fixed relative to the housing, that the piston divides the cylinder into two separate work spaces whose volume increase in each case to an opposite movement of the Slider leads, wherein two supply lines are provided for the hydraulic fluid to the working chambers, which consist of a central, through bore in the piston rod and an additional central tube, which is arranged in the bore, via the central tube hydraulic fluid in the first working space at the bottom of the piston and via the bore hydraulic fluid is supplied to the second working space, wherein a housing closing the rear piston rod latch a sensor for detecting an end stop position for the slide and the piston rod latch a square basic shape, d It fits through the square opening at the back of the housing so that the piston rod can be inserted through the square opening in the interior of the housing into the area of a cylindrical extension, so that after rotation of the piston rod bolt by 45 ° this with its corners according to Art a bayonet fitting behind the cylinder

  • the arrangement of slide and hydraulic drive with high symmetry can be done by the cylinder and the piston are arranged on the central axis / axis of movement of the slider. This creates a centric and symmetrical force introduction, which avoids the occurrence of tilting moments. This leads to less parasitic stress and increases the reliability and longevity of the assembly.
  • Linearwegschiebern according to conventional design would have resulted in a corresponding symmetrical design to significantly larger designs with an unacceptable specific performance.
  • the sliding guide which is arranged between the slide and the housing, is produced by a casting method.
  • a casting process leads to a high-quality sliding guide and at the same time is very cost-effective.

  • a hydraulic fluid e.g., oil
  • This supply line is arranged in the piston and in the piston rod connected to the piston.
  • a sensor for detecting an end stop position is provided on the piston rod latch. As a result, it can be determined and monitored whether the slide is located at one of the attachment points.

At its inlet opening, the cylinder sleeve 38 is closed by a sealing nut 30, so that the two hydraulic working chambers are completely formed in the cylinder sleeve 38.
  • Such an arrangement has the advantage that the hydraulic unit is completely stored in the cylinder sleeve 38 and therefore can be completely removed from the back of the inearwegschiebers 100 without the slide itself would have to be removed. Tools mounted on the slider, such as precisely aligned knives or the like, therefore, do not need to be removed. Thus, the risk of injury to the slide 12 is excluded by the distance. Furthermore, the hydraulic fluid is encapsulated in the cylinder sleeve 38 and therefore can the Do not contaminate installation site. Finally, the expansion of the blind hole of the slider 10 is avoided because the hydraulic pressure no longer acts directly on the slider 10. This is in view of the already tight tolerances of the slide gap of considerable advantage.
  • Fig. 6 the feature not according to the invention is shown that the hydraulic fluid is guided via two parallel supply lines 39 and 40 in the piston rod 31 to the rear or front working space.
