Novel blanking die waste cut-off tool structure

Abstract

The invention discloses a novel blanking die waste cut-off tool structure. The novel blanking die waste cut-off tool structure comprises a waste upper die tool block, a waste lower die tool block anda blanking tool block, wherein the waste upper die tool block is provided with a length-direction cutting edge and a width-direction cutting edge; the length-direction cutting edge is matched with a cutting edge of the waste lower die tool block; the blanking tool block is arranged on the side edge of the waste lower die tool block; a cutting edge of the blanking tool block is matched with the width-direction cutting edge on the waste upper die tool block; a pointed cone-shaped cutting edge protruding downwards is arranged at the intersection of the length-direction cutting edge and the width-direction cutting edge of the waste upper die tool block; and a space for the pointed cone-shaped cutting edge to descend is arranged between the waste lower die tool block and the blanking tool block. By the adoption of the novel blanking die waste cut-off tool structure, scrap iron can be avoided, the die repairing frequency is reduced, the production efficiency is improved, and the quality of ablanking piece product is improved.

Description

technical field [0001] The invention relates to the technical field of molds for manufacturing automobile parts, in particular to a novel waste material cutting knife structure for a blanking mold. Background technique [0002] A variety of molds are used in the manufacturing process of automobile parts, and the blanking mold is one of them. The blanking die is to use the stamping of the upper and lower dies to cut and separate the sheet material along the closed contour line, and use the material within the contour line as a die for blanking parts. During the blanking process, the material outside the contour line is an invalid sheet material. It is waste, which needs to be removed from the mold, and with the increasing size of auto parts and the requirements of production efficiency, it is usually required that the waste cutting knife can divide the waste into two parts or into multiple parts, and the mold is required to be in one Otherwise, the length of the mold will be...

The blanking die is to use the stamping of the upper and lower dies to cut and separate the sheet material along the closed contour line, and use the material within the contour line as a die for blanking parts. During the blanking process, the material outside the contour line is an invalid sheet material. It is waste, which needs to be removed from the mold, and with the increasing size of auto parts and the requirements of production efficiency, it is usually required that the waste cutting knife can divide the waste into two parts or into multiple parts, and the mold is required to be in one Otherwise, the length of the mold will be increased, which will increase the cost of the mold and the size requirements of the machine. However, when it is completed within one step, there will usually be secondary shearing at the intersection of the blanking part and the scrap, resulting in iron Chips, these iron filings brought into the mold will cause crushing on the working surface of the mold, and also cause convex defects on the surface of the stamping part, making the workpiece need to be repaired, affecting production efficiency and increasing production costs
