[0002] Forgings possess advantages such as high strength, fatigue resistance, and dense structure, and are widely used in various fields. Simple parts such as valves, joints, and flanges are produced using open-die forging, with forging presses and trimming machines used in conjunction for mass production. However, for small-batch forging, using two machines is expensive; moreover, two sets of tooling fixtures need to be made and disassembled, resulting in low processing efficiency. How to achieve efficient forging and trimming on a single press, thereby reducing the forging cost of small-batch products, is a major problem that needs to be solved. Utility Model Content

When performing the trimming operation, the punch fixing block frame 14 can be connected to the upper die pad 10 by the long screw 22, and the third screw 33 can be threaded to the third screw hole block 31 in the lower die pad 23 to fix the trimming die 17 on the lower die pad 23.

[0025] The operating principle of this utility model is as follows: First, four first screw hole blocks 26 are installed in the upper die pad 10, and the upper die pad 10 is fixed to the press worktable with an arc-shaped pressure plate. Four second screw hole blocks 30 are installed in the lower die base plate 25, and the lower die base plate 25 is also fixed to the press worktable with an arc-shaped pressure plate. If edge trimming is required, the punch fixing block frame 14 is connected to the upper die pad 10, and then the punch 16 and the punch fixing block 15 are connected together, with the punch fixing block 15 connected to the lower end of the punch fixing block frame 14. Four third screw hole blocks 31 are installed in the lower die pad 23, and the second screws 32 are tightened to the first screw hole blocks 26 in the lower die base plate 25, and then the third screws 33 are tightened to the third screw hole blocks 31 in the lower die pad 23 to fix the edge trimming pad 18.
