Stamping die and balance block component thereof

Abstract

The invention discloses a stamping die and a balance block component thereof. The balance block component comprises a lower balance block arranged on a blank holder and an upper balance block arranged on the lower balance block in a sliding mode, a guide structure and a locating structure are arranged between the upper balance block and lower balance block, the upper balance block is arranged at the lower balance block in a sliding mode along the guide structure, and the upper balance block is fixed at a preset position through the locating structure. By means of the sliding of the upper balance block relative to the lower balance block, the position of the upper balance block on the blank holder can be regulated according to the actual use requirements, the fine position adjustment for the working part of the balance block component is realized, the mounting position of the upper balance block can be regulated according to the use requirements, and the material press effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a balance block assembly for stamping dies. The present invention also relates to a stamping die comprising the above-mentioned balance weight assembly. Background technique [0002] At present, automobile body stamping parts are mainly realized by cold stamping. The forming process mainly includes processes such as drawing, trimming, punching, flanging, and shaping. The forming quality of the drawing process will directly affect the final quality of the product. For example, whether the thinning rate meets the requirements during drawing forming, whether there is wrinkling and cracking, and so on. [0003] The main process of drawing die forming is that the upper die moves downwards, the die and the blank holder compress the circumference of the blank, and then the upper die and the blank holder move downward together and are formed by the punch. The degree of compressio...

Problems solved by technology

However, after the existing balance weight 11 and blank holder 12 are installed, they are fixed and cannot be moved, and the installation position of the balance weight cannot be adjusted according to the needs of use, so the pressing effect cannot be guaranteed.
