Stamping continuous die for thick steel plate local fine stamping tooth-shaped product

Abstract

The invention discloses a stamping continuous die for a thick steel plate local fine stamping tooth-shaped product. The stamping continuous die comprises an upper supporting plate, upper cushion blocks, an upper die base, upper cushion plates, upper clamping plates, stop plates, stripping plates, lower die plates, lower cushion blocks, a lower die base, lower cushion blocks, lower supporting plates, a nitrogen spring ejector column knocking-out plate, upper die screws, screws, nitrogen springs, upper die inner guide columns, an equal-height sleeve, a guide pin, an upper die ejector cylinder, a spring, a set screw, lower die screws, punches, a lower die insert DB1, lower die inserts, plane inserts, an upper die dowel pin, a lower die dowel pin and a dowel bar top. Providing the continuous die through which two kinds of products are produced in the first section, and multiple procedures of punching, protrusion beating, cutting off, flanging and forming are combined into a whole is the purpose.

Description

technical field [0001] The utility model relates to a cold stamping die, in particular to a stamping continuous die for partial fine-punching tooth-shaped products of thick steel plates. Background technique [0002] Progressive die refers to the stamping die that uses coil material to stamp raw materials in one stamping stroke of the press, and uses several different stations on a pair of molds to complete multiple stamping processes at the same time. The positioning pitch is moved once, and the guide pin is used to finely position the material belt until the product is completed. 45# thick steel plate with a thickness of 5.0-6.0MM is punched to form a tooth-shaped product. It is necessary to use a continuous die to perform fine-blanking on the tooth-shaped part, and also need to pressurize the edge ring to prevent the material from being packed to deform the tooth during fine-blanking. The light material belt of the tooth profile is required to be above 90% T to ensure th...
