Accurate cutting and punching jump-scrap prevention mechanism

Abstract

The invention relates to an accurate cutting and punching jump-scrap prevention mechanism which comprises an upper die and a lower die, wherein the upper die comprises an upper die seat, an upper clamping plate and a stripper which are sequentially arranged from top to bottom, the lower die comprises a lower die plate, a lower die pad and a die seat which are sequentially arranged from top to bottom, equal-height bolts, springs and an inner guiding post are arranged in the upper die, a male die is arranged in the upper clamping plate, a female die which corresponds to the male die is arranged in the lower die plate, the male die comprises a rough stamping male die and an accurate cutting male die, the female die also comprises two sets which are respectively a female die A and a female die B, the female die A corresponds to the rough stamping male die up and down, and the female die B corresponds to the accurate cutting male die up and down. Through arranging the accurate cutting and punching jump-scrap prevention mechanism, the structure of the original stamping die is greatly optimized, the jump-scrap is prevented, the dimensional accuracy of a product is improved, the mass production of the products can be realized in the stamping die within a short time, a great deal of cost is saved, and the working efficiency and market competitiveness are improved.

Description

technical field [0001] The invention relates to a stamping die, in particular to a fine-cut punching anti-jumping mechanism of the stamping die, which belongs to the technical field of die design. Background technique [0002] For products whose sides are composed of slump angles, bright bands, fracture bands, and rough edges, the thickness of the bright bands on the product accounts for 30% of the total thickness of the product. However, the thickness of the bright bands must reach a minimum of 50% of the product thickness. The required product cannot be realized by using ordinary punching technology. It is necessary to adopt the method of rough punching and then finishing to meet the product requirements. However, the shape of the product waste during finishing is ring-shaped, and normal stripping cannot be performed, and material skipping is easy to occur. Indentation of the product, or cracking of the formwork. In view of these current situations, there is an urgent nee...
