Bent thick piece male die feed mechanism

Abstract

The invention discloses a bent thick piece male die feed mechanism. The mechanism comprises a female die, a lower die base, a left feed hook, an upper die base, a male die and a right feed hook, the male die is assembled at the bottom of the upper die base, the female die is arranged at the lower portion of the male die and installed on the lower die base through a female die assembly, the left feed hook is fixed at the upper end of the left side of the lower die base, and the right feed hook is fixed at the upper end of the right side of the lower die base; the mechanism is simple in structure, a pressing machine drives the upper die base to descend until the male die and the female die are in a closed state, and a part plate material is punched and bent to become a beam thick piece product; the upper die base drives the male die to lift, the left feed hook and the right feed hook block and strip the bent beam thick piece product on the male die to ensure that the product is strippedfrom the male die, and by adopting an installation mode of the left feed hook and the right feed hook block, the stripping effect is good; an air opening is communicated with the outside air, the situation that stripping is influenced due to negative pressure between the bent beam thick piece product and the male die is avoided, and the die cost is low.

Description

technical field [0001] The invention relates to the technical field of bending and forming, in particular to a feeding mechanism for a card punch for bending thick parts. Background technique [0002] With the continuous increase of vehicle products and the diversification of designs, the thick beam products used on vehicles also need to be constantly changed according to product design. However, during the stamping and forming process of the thick beam products, due to the excessive bending thickness, they are seriously stuck on the punch. In order to facilitate the removal of the thick beam products from the punch, usually the lower punch Spring ejector mechanism, this method not only increases the manufacturing cost of the mold and makes its structure complex, but also when the bent and formed thick beam product is clamped on the punch, it is difficult to ensure that the product can be ejected from the punch. In order to make the cost of the mold low, simplify its struct...
