Definitions

  • the invention relates to a punching device according to the preamble of Claim 1 and claims 9 and 13.
  • the present invention relates to punching devices, which are operated with a cylinder piston unit, which with a pressure medium is acted upon.
  • Such units have a piston and a cylinder, which correspond their dimensions are either high speeds or high pressures to produce. Large speeds are generated with pistons, the small ones Have piston area. In contrast, pistons with a large one Piston area high pressures.
  • the object of the invention is punching devices specify that allow a simplified structure and the Increase punching speeds of known punching devices.
  • this object is achieved by a punching device with the Features of claim 1 and / or the features of claim 9 solved.
  • the invention provides two mutually independent Solutions that are particularly advantageous in their combination are able to solve the problem according to the invention.
  • the first advantage of the invention is its compact design. This results both from the arrangement of the rapid traverse unit in the power gear unit as well as the Position the control unit as close as possible to the punching unit.
  • the compact Construction therefore enables the realization of the Punching device according to the invention in the form of a cart beam punch, in which the punching unit in the horizontal direction along a machine support is movably mounted.
  • Another advantage of the device according to the invention lies in the achievement high speeds of the punching unit, with up to 300 mm each Second almost doubles the known speeds. This advantage is also based in part on the combination according to the invention Rapid traverse and power unit as well as the special arrangement the control unit on the punching unit.
  • a preferred embodiment of the invention sees through a longitudinal bore the piston of the first cylinder piston unit through which the supply of the Print medium is particularly space-saving.
  • the cylinder and piston of the first cylinder-piston unit form an annular cavity provided, which is tightly sealed on the front.
  • the feed line is advantageously in the cylinder wall of the cylinder integrated the first cylinder piston unit.
  • Another advantage of the invention results from the use of large volumes Lines through which the control element to the cavity of the cylinder of the first Cylinder-piston unit is connected, so that a smooth running of the Ensure pressure medium while operating the rapid traverse unit.
  • all pressure lines of the Line system from the control element to the rapid or power unit lead, integrated in the punching unit.
  • all pressure lines of the Line system from the control element to the rapid or power unit lead, integrated in the punching unit.
  • the top of the base is designed as a punching table 5, on which the processing workpiece, for example a paper stack for the punching process is fixed.
  • lateral supports 6 and 7 protrude from the Punching table out. Their upper ends are together via the superstructure 8 connected.
  • the punching unit 9 is in horizontally fixed between the two supports 6 and 7 movable.
  • the punching unit 9 consists essentially of a block-shaped Base element 10, on the top of which a control unit 11 is arranged and from the underside of which the drive 12 for lowering the tool carrier 13 extends in the direction of the punching table 5.
  • the substructure 2 is designed such that it also serves as a container 14 for the Media serves.
  • the container is connected via a line system 15 to the Punching unit 9 connected.
  • the lines 16 and 18 thus form with the punching unit 9 and the container 14 Circulatory system.
  • the punching unit 9 has block or plate-shaped base element 10. From the top of the Base element 10 extend two upright perpendicular to the plane of representation Tabs 19 and 20, on the facing sides of the rollers 21 and 22 with Direction of rotation are also arranged perpendicular to the plane of representation. The Rollers 21 and 22 engage in the rails 23 and 24, the side on Machine support 25 of the superstructure 8 are attached. This is the basic element Movably fastened to the machine support 25 along the running rails.
  • a control unit 11 which via the line system 15 (Fig. 1) with the Media can be applied.
  • dashed lines is one alternative arrangement of the control unit 11 centrally above the punching unit 9 shown.
  • the Machine carrier 25 can be divided in two in the longitudinal direction with a corresponding one
  • the bottom of the Control unit 11 is provided with various closable inlets and outlets Control of the punching unit 9 provided.
  • the drive 12 extends perpendicularly from the underside of the base element 10 of the punching unit 9.
  • the drive 12 consists essentially of a first Cylinder-piston unit, the cylinder 26 of which is by means of an upper ring flange 38 is rigidly connected to the base element 10.
  • the lower end of the hollow cylinder 26 is also reinforced by an annular flange 39 in its flange surface Four circular perforations evenly distributed over the circumference are inserted into which slide guides 41 are inserted.
  • the piston 27 also acts in the form of a hollow cylinder together.
  • annular seals 40 provided that a tight sliding connection to the inner wall of the Allow cylinders 26.
  • the surface of the piston 27 jumps radially back inwards so that an annular gap 28 between piston 27 and Cylinder 26 results.
  • the lower end of the piston 27 is via a sleeve-shaped sealing sleeve 29 extended.
  • Their inner diameter is such on the outer diameter of the Piston 27 tuned that a sliding seal is also achieved here is, so that the annular gap 28 is sealed on both end faces.
  • the lower end of the piston 27 is fixed to the tool carrier unit 13 connected, so that by lifting and lowering the piston 27 of the Tool carrier 13 is brought into the punching position.
  • a second one Cylinder-piston unit Inside the piston 27 of the first cylinder piston unit is a second one Cylinder-piston unit arranged, the piston 31 fixed with its upper end is connected to the base element 10.
  • the moving part of the Cylinder-piston unit is the cylinder 32, which is fixed via the ring flange 33 is connected to the upper end of the piston 27.
  • the Ring flange 33 for a sliding seal between piston 31 and cylinder 32.
  • the first and second cylinder piston units, which drive the 12 Punching unit 9 form, are integrated pressure lines with the Control 11 connected.
  • the pressure line 34 supplies the second Cylinder-piston unit with pressure, for which the piston 31 has a central longitudinal bore 42 has.
  • Another pressure line 44 which in the wall of the cylinder 26th is integrated and opens into the annular gap 28, is also to the control unit 11 connected.
  • Another pressure line 37 leads from the control element 11 to Punching space 35.
  • the filling valve 45 on the control unit 11 enables the lines 46 to be closed.
  • the tool carrier 13 with the punching tools from a starting position, as shown in FIG left half of the sheet is shown, as quickly as possible in the area of the punched Workpiece are driven.
  • a line 34 is used Pressure medium under pressure in the cylinder 32 of the second cylinder piston unit promoted. Due to the small piston area, the cylinder 32 moves with it great speed down. Due to the rigid connection of the pistons 27 and 32, the piston 27 is taken along and thus the tool carrier moved down at high speed. At this rapid Downward movement can via the large-volume pressure lines 43 Large quantities of pressure medium from the control unit 11 into the punching space 35 flow without interfering with the downward movement of the piston 27.
  • control unit 11 After running through a predetermined distance, the control unit 11 also closes With the help of a valve the supply of the pressure medium to the large volume Pressure line 43 and acts on the punching space 35 via the pressure line 37 Print. As a result of the large piston area of the piston 27, it becomes large Generates pressures with which the actual punching work is carried out.
  • the annular gap 28 is pressurized via the pressure line 37 acted upon, with the simultaneous opening of the valve, the pressure medium displaced again from the punching space 35 and flow back into the container 14 can.
  • FIG. 3 included hydraulic diagram included.
