Blanking device of nonuniform section iron core in progressive die

Abstract

The invention relates to a blanking device of a nonuniform section iron core in a progressive die. The blanking device comprises a plurality of overlapped first male molds, wherein the plurality of first male molds are respectively provided with eight second male molds at both sides; the lengths of the eight male molds decrease successively; the two second male molds with the largest lengths are respectively arranged on the top face and the bottom face of the first male molds; the length of the first male moles is larger than that of the largest one of the second male molds; the first male molds and the second male molds are provided with three snap riveting points; a pressing rod is arranged in the first male molds; the bottom faces of the first male molds protrude out of the bottom face of the pressing rod; the second male molds are provided with a male mold top head; and the male mold top head is provided with a movable male mold drawing plate. The blanking device provided by the invention has the beneficial effect of eliminating the influence on product size by worker factors during assembling a single sheet to form the iron core in the past, greatly improving the stability of product size, and substantially increasing the intelligence, humanization and reasonability of the die.

Description

technical field [0001] The invention relates to a blanking device for an iron core with non-constant section in a progressive die. Background technique [0002] At present, the production process of non-constant section iron core products is as follows: according to the different widths of the parts, a single silicon steel sheet of various buckle riveting points is punched out, and then assembled and riveted manually through a fixture. It has low efficiency and poor product quality stability. The outer dimension of the iron core is greatly affected by human factors. Due to the increasingly strict requirements of the manufacturer on the size of the product, this production process is difficult to meet the use requirements of the product. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a blanking device for a non-constant section iron core in a progressive die, which eliminates the influence of the worker's factor on the product size in ...
