The working process of the utility model is as follows:

a worker installs the upper support on a stamping connecting head of the stamping machine; the worker places the bottom surface of the stamped part 28 flat against the top surface of the lower ram 17 as shown in fig. 4; the workman operates the punching machine and makes its punching press connector downstream, and the punching press connector drives the mould downstream, because last pressure head 10 is located stripper 5 below, consequently stretch into in the part 28 earlier and down the arch portion of part 28, when the stripper 5 closed the mould promptly with the die board 14 contact, go up pressure head 10 and no longer down the arch portion, if the distance between the bottom surface of last pressure head 10 and the top surface of last pressure head 10 just equals the thickness of part this moment, the arch portion is pressed the level and smooth as shown in figure 6 completely to the repairment of part has been realized. After trimming, the punch is operated to reset the upper die in preparation for trimming the next part.

If the part 28 is to be trimmed to a part with a slightly convex arch part, a worker only needs to unscrew the locking screw 24 rightwards, after the screw head of the locking screw 24 is separated from the vertical plate, the worker does not unscrew the locking screw 24 any more, then screws the screw head of the fine adjustment screw 23, the fine adjustment screw 23 is in threaded connection with the threaded hole I21, so that the vertical plate moves rightwards, the vertical plate drives the fine adjustment plate 19 to move rightwards horizontally, and because the inclined plane B20 is matched with the inclined plane A18, the lower shaping block 16 synchronously moves downwards along the guide groove 15 while the fine adjustment plate 19 moves rightwards, so that the purpose of increasing the distance between the bottom surface of the upper pressure head 10 and the top surface of the upper pressure head 10 is achieved, and the locking screw 24 is screwed again after the fine adjustment. When the part is to be trimmed, the bottom surface of the part is placed flat on the top surface of the lower ram 17 as shown in fig. 4, and after the mold is closed, the upper ram 10 can press the arch down only a distance due to the increased distance between the bottom surface of the upper ram 10 and the top surface of the upper ram 10, thereby trimming the part to a slightly convex arch. Therefore, the die can trim the arched part of the part subjected to punch forming into a plane or an arched part with a slight bulge, in addition, in the whole trimming process, a pressure head is not required to be held by a worker for trimming, and the part can be quickly trimmed only by operating a punching machine, so that the labor intensity of the worker is greatly reduced, and the trimming efficiency of the part is also improved.
