Problems solved by technology

In a lot of practical work, it is found that conventional blanking dies generally have the following defects: the cutting edge of the die, the hole pattern is usually designed in the form of a slope with the cutting edge
If the blade wall of the die has a slope, the workpiece or waste is easy to fall from the blade hole during punching, but the strength of the blade is low, and it cannot be re-sharpened once it is worn.

Abstract

The invention belongs to the field of molds, and discloses a blanking mold. The blanking mold comprises a mold frame, a convex mold and a concave mold, wherein the mold frame comprises an upper mold frame and a lower mold frame. The blanking mold further comprises a connecting rod; the concave mold is connected with the upper mold frame; the convex mold is connected with the lower mold frame; a cross beam is additionally arranged above the upper mold frame; a first spring is arranged on the cross beam; one end of the connecting rod is disc-shaped, and is positioned in the concave mold; the connecting rod is connected with the first spring; a second spring is arranged on the convex mold; and the convex mold and the concave mold are straight edges. The blanking mold can increase the repeated cutter sharpening repair times to prolong the service life.

Description

technical field [0001] The invention relates to a die, in particular to a blanking die. Background technique [0002] Punching is a stamping process that uses a die to separate part of the material or process from another part of the material or waste. In most plastic processing processes, it is hoped that the material can withstand large plastic deformation without being damaged, so as to form products of a certain shape and size. The blanking process includes multiple processes such as blanking, punching, cutting, notching, and edge trimming. In the whole process, the quality of the blanking die greatly affects the quality of the product. [0003] The design of the blanking die is the basis and core of the blanking process. In the design of blanking dies, it is found that the quality and service life of the dies are affected by factors such as the design structure of the dies, the gap between the concave and convex dies, the characteristics of the materials used in the ...
