Background

The stamping die is a special process equipment which applies a certain pressure to a metal or nonmetal plate by using a die fixed on a punch press or a pressing machine to separate or form the material so as to obtain a part with a certain size requirement and qualified appearance quality.

The general stamping die usually comprises a die holder, a template, a stripper plate and other structures, and when the stamping die works, a part can be rapidly stamped and formed by placing the part between an upper die and a lower die. However, some special-shaped parts include some non-punching parts exposed outside the upper and lower dies besides the punching area. When such a part is formed by press molding, the press area is pressed by the press, and the non-press portion tends to be suspended from the outside without being subjected to a force. The product is difficult to be positioned smoothly due to stress difference between the two, so that the problem of bending and even more serious fracture of the punched part is caused, and the punching quality is greatly influenced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-2, the utility model provides a dysmorphism product stamping die 100, include lower bolster 10, lower bolster 20, the upper stripper 30, punch holder 40 and the upper die base 50 of coincide in proper order from bottom to top, be equipped with spacing post 60 in a plurality of and spacing post 70 outward between upper die base 50 and the lower bolster 10, be equipped with supporting component 80 on the lower bolster 10, supporting component 80 includes fixed block 81, bracing piece 82 and spring 83.

The fixing block 81 is provided with a fixing groove 811, the lower end of the supporting rod 82 is movably embedded in the fixing groove 811 of the fixing block 81, the spring 83 is installed in the fixing groove 811 and located between the fixing block 81 and the supporting rod 82, and the fixing block 81 is fixed at one side edge of the lower die holder 10. The upper end of the supporting rod 82 is contacted with a non-stamping part of a part, and when the part is pressed down due to gravity during stamping forming, the supporting rod 82 also descends along with the part; the spring 83 at the lower end of the supporting rod 82 is pressed to provide upward elastic force, so that the supporting rod 82 reversely supports the non-stamping part of the part, the downward pressing gravity and the supporting elastic force tend to be balanced, the whole non-stamping part of the part is in an unstressed state, and the stamped part is smoother.

The fixing block 81 includes a main body 812 and an extension 813 extending toward the main body 812, and an installation groove 11 is formed in an edge of one side of the lower die base 10. The extension part 813 is embedded in the installation groove 11, and the main body part 812 is positioned at one side of the lower die holder 10.
