Press for producing fine cut parts

Abstract

A press for producing fine cut parts includes a tool holder, a cross-beam and a tool having a plurality of tool parts, wherein the tool includes a tool block. The tool holder includes a set of transmission devices. The cross-beam is drivingly connected, via the set of transmission devices, to at least some of the tool parts required to produce a fine cut part and arranged in the tool block. The cross-beam is actuated by at least two cross-beam drives.

1 . A press for producing fine cut parts, having a tool holder, a cross-beam and a tool having a plurality of tool parts, wherein the tool comprises a tool block, wherein the tool holder comprises a set of transmission devices, wherein the cross-beam is drivingly connected, via the set of transmission devices, to at least some of the tool parts required to produce a fine cut part and arranged in the tool block, and wherein the cross-beam is actuated by at least two cross-beam drives. 
     
     
         2 . The press as claimed in  claim 1  wherein the press comprises a second tool holder and a second cross-beam, and in that the tool comprises a second tool block, wherein the second tool holder comprises a second set of transmission devices, wherein the second cross-beam is drivingly connected, via the second set of transmission devices, to at least some of the tool parts required to produce a fine cut part and arranged in the second tool block, and wherein the second cross-beam is actuated by at least two cross-beam drives. 
     
     
         3 . The press of  claim 1  wherein the first cross-beam is drivingly connected, via the first set of transmission devices, to all the tool parts arranged in the first tool block which apply a knife-edge ring force and/or a counter-holding force to a workpiece and/or the second cross-beam is drivingly connected, via the second set of transmission devices, to all the tool parts arranged in the second tool block which apply a knife-edge ring force and/or a counter-holding force to a workpiece. 
     
     
         4 . The press of  claim 1  wherein the first cross-beam is drivingly connected, via the first set of transmission devices, to all the tool parts required to produce a fine cut part and arranged in the first tool block, and/or the second cross-beam is drivingly connected, via the second set of transmission devices, to all the tool parts required to produce a fine cut part and arranged in the second tool block. 
     
     
         5 . The press of  claim 1  wherein each tool part required to produce a fine cut part is drivingly connected to a transmission devices in each case. 
     
     
         6 . The press of  claim 1  wherein the transmission devices are pressure pins. 
     
     
         7 . The press of  claim 6  wherein the first and/or second tool holder comprises a plurality of receivers for pressure pins, in particular wherein more receivers are provided than are necessary for producing a fine cut part. 
     
     
         8 . The press of  claim 1  wherein each cross-beam is actuated by at least two and preferably no more than three cross-beam drives. 
     
     
         9 . The press of  claim 1  wherein the cross-beam drives of the first cross-beam and/or the cross-beam drives of the second cross-beam are each mutually force-controlled. 
     
     
         10 . The press of  claim 1  wherein the cross-beam drives of the first cross-beam and/or the cross-beam drives of the second cross-beam are each driven by a single drive unit. 
     
     
         11 . The press of  claim 1  wherein the cross-beam drives of the first cross-beam and the cross-beam drives of the second cross-beam are driven by a single drive unit. 
     
     
         12 . The press of  claim 1  wherein the press is a servo-driven toggle press which comprises in particular a 2-toggle system operated by at least one drive unit. 
     
     
         13 . The press of  claim 1  wherein the press has a maximum pressing force of 1500 kN, and/or a press table length of up to 4.0 m. 
     
     
         14 . The press of  claim 13  wherein the press has a maximum pressing force of 1100 kN and/or a press table length of up to 3.5 m.
