Definitions
- the invention relates to a device for punching and die-cut stacks of punching plates after in the preamble of claim 1 defined in more detail Art.
- From DE 26 05 983 C3 is a device known for stuttering and stauzsentjan stacking of baffle plates.
- the stamped sheets are hereby on a thorn stacked or guided, located in the receiving shaft for the punching plates below the punch located and receives the sheets on its inner bore.
- FR 2289267 From the generic FR 2289267 is a punching device with a Punching tool known, whose die a passage to Recording the punching plates has.
- a mandrel On which the string punched sheets into a stack.
- a transport mandrel Below the Stapeldorns is arranged a transport mandrel. Laterally adjustable slides control the transfer of the punching plates from the stack mandrel to the transport mandrel.
- the stacking mandrel as well as the transport mandrel is to the adapted punching sheets.
- the punching tool need the stacking mandrel and the transport mandrel in usually be retrofitted.
- the clamping elements formed a stacking so that even during a Application of the punching plates a continuous punching the sheets is possible. Furthermore, a Rotation of the punching plates by the invention Clamping elements are prevented.
- Fig. 1 shows a device 1 for punching and stamping Stacking of preferably round punching plates 2, which by a tool shell or a Stamp 3 and cooperating with the stamp 3 Tool lower part or die 4 from a Sheet metal strip 5 produced in a conventional manner become.
- punching plates 2 made with a geometry other than a round one become.
- the support element 7 has on its underside a lifting device 9, in this Case a pneumatic or hydraulic cylinder / piston unit on which is able to do that Support element 7 during the punching of the sheets. 2 to move down. That's the way it is ensured that constantly punched new punching plates 2 be and get into the receiving shaft 6 can. If necessary, the lifting device 9, the support element 7 move up again. For this can the lifting device 9 with a not shown Control of the punch 3 to be connected. alternative can the lifting device 9 as electrical Lifting device 9 or designed as a linear drive be. In this context, it is possible the Lifting device 9 to couple with the punch 3, that the support element 7 at each stroke of the punch 3 to move the thickness of a punching plate 2 down becomes.
- a guide device 10 for guiding the punching plates 2.
- the guide device 10 has two each other opposite, on the circumference of the punching plates. 2 acting clamping elements 11, which at their the Punching plates 2 facing side formed prismatic are.
- the clamping elements 11 are at their the Punching plates 2 opposite side with a drive device 12 connected, which is capable is, the clamping elements 11 perpendicular to the punching direction move towards the punching plates 2 and move away from them.
- the drive device 12 is in the present Case a pneumatic or hydraulic cylinder / piston unit, However, if necessary, by be formed an electric drive.
- the clamping elements 11 are guide elements 13, which with a fastening element 14th connected directly below the lower tool part 4 are.
- the guide elements 13 are prismatic formed, which can be seen in Fig. 2. Between Guide elements 13 thus become the die 4 leaving punching plates 2 led before they in the Area of the clamping elements 11 arrive. This prevents the displacement of the punching plates 2.
- the twisting of the Punching sheets 2 is prevented by the sheet stack 8 under axial pressure between the jacket of Die 4 and the lifting device 9 and the clamping elements 11 is clamped. This will be the possibility for a stampable stacking of the punching plates 2 created.
- the entire guide device 10, i. the clamping elements 11 with the drive device 12, can by another drive means 15 in vertical Direction, i. in the direction of a longitudinal axis 16 of the Receiving shaft 6 or in the punching direction in height be adjusted.
- the longitudinal axis 16 thus also forms the longitudinal axis of the punch 3.
- the drive means 12 and 15 are each in the present case as Cylinder / piston units hydraulic or pneumatic Art educated, however, may be appropriate be replaced by electric drives.
- the Drive devices 15 are located on each a carriage 17 which is mounted on a frame 18 is which part of the device 1 is.
- a diameter adjustment 19 are moved whereby the carriage 17 is perpendicular to the longitudinal axis 16 is adjusted.
- the drive device 20 can in this case electric, hydraulic, pneumatic or in one be formed in any other form, the Spindle 21 is not absolutely necessary.
- Fig. 1 can also be seen that the support element 7 is formed rake-shaped with tines 22, which extends in the direction of the longitudinal axis 16 of the receiving shaft 6 extend.
- the tines 22 are the Punching plates 2 stored in the form of sheet stack 8. Between the tines 22 are perpendicular to the same and perpendicular to the longitudinal axis 16 conveyor chains 23 for Transport of the sheet stack 8. Will the support element. 7 moved down by the lifting device 9, so comes the corresponding sheet stack 8 at a certain Point to lie on the conveyor chains 23 and is of its position below the receiving shaft 6 carried away.
- the punching plates 2 are initially on the support element 7 piled up. If a preselected amount of Sheet stack 8 is reached, move the clamping elements 11 and hold the lower punching plates 2 of the sheet stack 8 firmly. The support element 7 then moves down and places the severed punching plates 2 on the conveyor chain 23 from. While this process is running the punching of the punching plates 2 on, wherein the punching plates 2 from the bottom between the guide elements 13 located punching plate 2 collected become. In other words, when branching off a certain amount of punching plates 2 from the sheet stack 8 the separation of the branched punching plates 2 of the remaining punching plates 2 through the bottom still between the guide elements 13 located stamping sheet 2 formed, which thus represents a stacking switch.
- the stroke of the punch 3 can be used be to the gradual lowering of the punching plates 2 to reach.
- Fig. 3 which is a view of the clamping elements 11th and the guide elements 13 starting from a view from the longitudinal axis 16, the formation of the Clamping elements 11 and the guide elements 13 can be seen.
- the guide elements 13 are namely rake-shaped with tines 24 and between the tines 24 itself located free spaces 25 formed.
- the Clamping elements 11 have tines 26 and between the Tines 26 formed free spaces 27.
- the two elements 11 and 13 are arranged so that the tines 24 the guide elements 13 in the free spaces 27 of the clamping elements 11 engage, and the prongs 26 of the clamping elements 11 in the free spaces 25 of the guide elements 13 intervene.
- the free spaces 25 and 27 are included almost as wide as the tines 24 and 26, so that a guide of the punching plates 2 by the guide elements 13 and the clamping elements 11 is given.
