Guide structure for blanking die

Abstract

The invention discloses a guide structure for a blanking die. The guide structure for the blanking die is stable in guidance and comprises a vertical guide sleeve arranged at the lower portion of an upper die holder and a vertical guide column arranged at the upper portion of a lower die holder. The diameter of the guide sleeve is larger than that of the guide column. The upper portion of the guide column penetrates into the guide sleeve. An annular holding frame is arranged on the inner wall of the guide sleeve and provided with multiple balls. The balls are obliquely arranged in parallel at equal intervals.

Description

technical field [0001] The invention relates to a guide structure for a blanking die. Background technique [0002] Blanking is a stamping method that separates parts or blanks of required shape and size from sheet metal. The main equipment used is the punching die. The main structure of the blanking die includes an upper die base, an upper die set under the upper die base, a lower die base, a lower die set on the upper part of the lower die base, and a material guide plate arranged on the upper part of the lower die base and located on both sides of the lower die base. The height of the material guide plate is higher than that of the lower die, and the lower part of the upper punch is usually made into a boss matching the blank blanking shape, and the size of the boss is basically the same as that of the die. In order to make the upper die seat drive The movement of the upper punch is stable. Usually, a guide post is provided at the lower part of the mold base, and a guid...

The main structure of the blanking die includes an upper die base, an upper die set under the upper die base, a lower die base, a lower die set on the upper part of the lower die base, and a material guide plate arranged on the upper part of the lower die base and located on both sides of the lower die base. The height of the material guide plate is higher than that of the lower die, and the lower part of the upper punch is usually made into a boss matching the blank blanking shape, and the size of the boss is basically the same as that of the die. In order to make the upper die seat drive The movement of the upper punch is stable. Usually, a guide post is set at the lower part of the mold base, and a guide hole is opened on the lower mold base. The guide post and the guide hole are guided through the sliding fit, but the above-mentioned guide structure has poor guiding stability.
