Problems solved by technology

[0002] In the bending process of some large and large-sized bending workpieces, if the conventional press is used for blanking processing, the mold needs to be replaced many times, and the labor intensity is high, and there are many influencing factors in the production, which will cause the product quality to be unstable. , it is difficult to meet the technical requirements of the drawings, and the production efficiency is low; if a large CNC turret punch press is used, not only the cost is high, but the production efficiency is low, which cannot meet the production needs

Abstract

The invention discloses a blanking forming die for a bending machine. The blanking forming die for the bending machine comprises an upper die and a lower die, wherein the upper die is composed of a terrace die fixing plate, a guide sleeve and an elastomer clamped between the terrace die fixing plate and the guide sleeve; a terrace die is mounted inside the guide sleeve, and the top end of the terrace die is fixed onto the terrace die fixing plate; the guide sleeve is vertically mounted at the front end of the above of the terrace die, a spring is arranged between the guide sleeve and a die body, and the rear of the guide sleeve is provided with a limiting baffle; the front end of the bottom of the die body is provided with a cavity die, a positioning pin is vertically mounted in the center of the cavity die, and the die body is fixed onto a lower die fixing plate through a bolt. The blanking forming die for the bending machine is stable in blanking processes, capable of achieving one-step forming, high in working efficiency and low in cost, and under the action of the lower die positioning pin, is accurate in positioning and high in hole distance precision.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to a blanking forming mold for a bending machine. Background technique [0002] In the bending process of some large and large-sized bending workpieces, if the conventional press is used for blanking processing, the mold needs to be replaced many times, and the labor intensity is high, and there are many influencing factors in the production, which will cause the product quality to be unstable. , it is difficult to meet the technical requirements of the drawings, and the production efficiency is low; if a large CNC turret punch press is used, not only the cost is high, but the production efficiency is low, which cannot meet the production needs. Contents of the invention [0003] In order to solve the problems in the background technology, the object of the present invention is to provide a blanking mold for a bending machine. By using the mold, a large-sized workpiece ca...
