【Abstract】 The extrusion founding test for forming the 4Cr5MoSiV-steel forging die was briefly introduced. All the improvements in the structure of the founding die and the operation of the die were stated. Continuous 3-stage stripping realized within one return stroke of the press cross-beam under certain test conditions. The points needing attention in using the extrusion founding die were listed.更多还原
