Method for operating a press indirect extrusion press indirect extrusion

摘要

Method for operating a press indirect extrusion (10), the press indirect extrusion (10) an indirect punch (12) with a tool head (14) can stay in the indirect punch (12) comprising a piece of lock (16) and a device housing block (18) movable longitudinally accommodation block of material (20) for receiving a block of material (22), can move straight device housing block ( 18) by the closure part (16) through indirect punch (12) being removable indirect punch (12) by movement of the housing block (18) in the direction of the closing piece (16) the housing block of material (20) and being insertable in this by moving in the opposite direction, being provided after pressing a block of material (22) and the configuration of a crust (24) in a chamber crust (26) in the method the following steps: (A) extracting the indirect punch (12) of the housing block material (20) by movement of the housing block (18) in the direction of the closing part (16), (B) providing a head of additional tool (28) between indirect punch (12) and housing material block (20) and receiving the head of additional tool (28) in indirect punch (12), (C) introducing the indirect punch (12) in the housing block of material (20) together with the tool head (28) housed and contacting the head of additional tool (28) with another tool head (14) by moving additional device housing block in the opposite direction, and (D) ejecting push the other tool head (14) of the housing block material (20) by further movement of the housing block (18) in the opposite direction, ejected po r pressure in the further movement the crust (24) by additional tool head (28) partially or completely block the housing material (20).
