Tool cartridge having an elastic matrix

Abstract

A press for massive forming has a tool frame used for closing matrixes which form mold halves for a forming operation which takes place in the closed mold. The closing devices contain driving devices and, together with these, are housed in or on the cartridge. They are formed by a spring device, in which the closing force is applied by the closing device (spring, pneumatic spring, ring piston with nitrogen reservoir). The closing movement is carried out by the slide movement.

1 . Tool cartridge, for a massive forming press for massive forming, which tool cartridge is set up for connection with a tool frame, arranged in the press, and has a plurality of tool receiving devices operatively assigned to tools for successive forming stations, comprising: 
 matrixes configured to be insertable in the tool receiving devices or are inserted thereon and which each is part of a tool;    at least one guide for the movable bearing of the matrix, wherein the at least one guide is arranged in or on the tool cartridge and is operatively associated with to the tool receiving device, at which the matrix is to be movably disposed;    at least one punch operatively associated with the at least one movably disposed matrix and which is stationarily disposed in the tool frame, and    at least one closing device assigned to the tool cartridge and to the movably disposed matrix and which is arranged completely in or on the tool cartridge.    
     
     
         2 . Tool cartridge according to    claim 1   , wherein the closing device is a spring device.  
     
     
         3 . Tool cartridge according to    claim 1   , wherein the guide has a guiding direction which coincides with a working direction defined by the press, and the matrix is prestressed by the closing device against the working direction of the press.  
     
     
         4 . Tool cartridge according to    claim 3   , wherein the spring device is enclosed by the tool cartridge.  
     
     
         5 . Tool cartridge according to    claim 2   , wherein the spring device is a pneumatic or hydraulic spring device.  
     
     
         6 . Tool cartridge according to    claim 2   , wherein the spring device has at least one mechanical spring element.  
     
     
         7 . Tool cartridge according to    claim 1   , wherein ejector devices are associated with at least the tool receiving devices on which matrixes are arranged and are movably disposable.  
     
     
         8 . Tool cartridge according to    claim 1   , wherein the closing device is comprising an adjusting device for adjusting a closing force or a characteristic force-path curve.  
     
     
         9 . Tool cartridge according to    claim 1   , wherein a conical receiving device operatively connects the tool cartridge with the tool frame.  
     
     
         10 . Tool cartridge according to    claim 9   , wherein the conical receiving device includes mechanically or manually operated tensioning devices.
