Quick adjusting device for bending springback of stamping die

Abstract

The invention discloses a quick adjusting device for bending springback of a stamping die. The quick adjusting device for bending springback of the stamping die comprises a lower table top assembly and an upper punch assembly, wherein the lower table top assembly comprises a lower die plate installed on a lower table top, a lower die adjusting block and an adjusting driving block; the adjusting driving block is arranged beside the lower die adjusting block; the upper punch assembly comprises a material pressing plate and a bending assembly which are installed at an upper drive bottom; the material pressing plate is connected to the upper drive bottom through a spring; the bending assembly comprises an adjusting fixing base; a channel allowing the adjusting fixing base to penetrate through is formed in the material pressing plate; the bottom of the adjusting fixing base is connected with a bending adjusting block jointly matched with the adjusting drive block and the lower die adjusting block; the side face of the bending adjusting block is a bending molded surface; the top face of the bending adjusting block is hinged to the bottom of the adjusting fixing base through a rotating shaft; and the bending adjusting block abuts against the bending adjusting block from the bottom through the adjusting driving block to drive the bending adjusting block to rotate so as to extrude a product. According to the quick adjusting device for bending springback of the stamping die provided by the invention, the springback amount of a stamped part can be controlled more effectively and accurately.

Description

Technical field [0001] The present invention relates to the field of machining, and in particular, to a stamping mold. Background technique [0002] Due to the electrical control of the new energy vehicle, the copper row of the electric drive uses a stamped fracture (coated) structure. The accuracy plays an important role in the entire assembly quality. Its precision requires greatly above the general car stamping parts, of which the copper row The angle of bend is extremely difficult. The size of the stamped material is exposed directly to the accuracy of the stamping parts. However, the material itself, the mold processing accuracy, the state of punching, etc. affect the amount of bending rebound. Therefore, the rebounded amount of the bend angle is to be tested, and the mold adjustment is performed according to the measured value, and a relatively accurate value can be obtained. [0003] The method of normal adjustment of stamping parts is to change the size of the components ...
