If the handle 400 is pulled further, the second die holder 300 will be separated from the adjacent second die holder 300, and during the separation process, the second connecting rod 360 of the adjacent second die holder 300 will be pulled, and the second connecting rod 360 slides along the guide chute 370 and slides to the end of the guide chute 370 close to the first die holder 200. In the above process, the second rotating element of the adjacent second die holder 300 is also pulled and rotates along with the sliding of the second connecting column 360, and at this time, the adjacent second die holder 300 repeats the changing process of the second die holder 300 (i.e., the change from the first rotation stop point to the third rotation stop point is repeated, and the action principle of the subsequent pulling process is the same, and thus is not repeated), as shown in fig. 9 to 11.

Through the design, the second die holders 300 can be pulled out one by one only by pulling the handle 400, and the second die holder 300 positioned at the outer side is pulled out first, and the second die holder 300 positioned at the inner side is pulled out later. Because when the positioning rod 380 is not pulled out from the positioning hole 381, the corresponding second rotating shaft 320 cannot rotate, that is, in this embodiment, only when the second die holder 300 located on the outer side is completely pulled out, the other second die holder 300 adjacent to the second die holder can be pulled, so that it can be ensured that the second die holder 300 located on the outer side is completely pulled out, the second die holder 300 located inside can be pulled out, and the distances of pulling out each second die holder 300 are the same. When the second die holder 300 located at the outer side is completely pulled out, a gasket can be filled into the gap, and the thickness of the gasket is set to be the same as the pulling-out distance of the second die holder 300, so that the gasket can lock the pulled-out second die holder 300 to prevent the second die holder 300 from retracting again, and the bearing area of the whole multipurpose stamping die 1000 is increased.

More shims can be filled in by pulling out more of the second die holder 300, thereby making the multi-purpose stamping die 1000 wider to accommodate different sized machined parts.

It should be noted that, with the above design, when the second die holder 300 needs to be reset, the inner second die holder 300 is reset first, and then the second die holders 300 located on the outer sides are reset one by one, and when the second die holder 300 is reset, the positioning rod 380 will be re-fitted into the positioning hole 381 under the action of the elastic member 391 to form locking. Thus, when the width of the multipurpose stamping die 1000 is reduced, the gaskets can be taken out one by one, and the width of the multipurpose stamping die 1000 is gradually reduced to meet different use requirements.

Multipurpose stamping die 1000 can provide multiple use width afterwards for hydraulic punching equipment 2000 can be applicable to the stamping process of different specification and dimension parts, adjusts convenient and fast more, and simple to use not only can improve production efficiency, can also avoid the machining precision to receive the influence.

Further, the end of the arc-shaped sliding groove 350 close to the first die holder 200 is provided with an expanding section 351, and the groove width of the arc-shaped sliding groove 350 is increased towards two sides at the expanding section 351. Through this design, make the slip of locating lever 380 in arc spout 350 more smooth and easy, help the second to rotate the piece and fully rotate, avoid second die holder 300 to pull out inadequately.

In this embodiment, as shown in fig. 12, the positioning rod 380 includes a first rod 382, a second rod 383, and a third rod 384, wherein the first rod 382 and the third rod 384 are both in a long strip shape and perpendicular to each other, the second rod 383 is in a circular arc shape, and the first rod 382 and the third rod 384 are respectively disposed at two ends of the second rod 383 and connected to an end of the second rod 383. The first rod 382 is slidably engaged with the positioning slot 390 via a first positioning block 385, and the rear end of the third rod 384 is slidably engaged with the arc-shaped slot 350 via a second positioning block 386. Through this design, not only can make the slip of locating lever 380 more smooth and easy, but also can utilize second body of rod 383 to effectively dodge second pivot 320.
