Semiautomatic punching mold and punching method thereof

Abstract

The invention provides a semiautomatic punching mold. The semiautomatic punching mold comprises an upper mold base and a lower mold base used for clamping and supporting a part to be punched, an upper stripper plate for pressing and stripping a material and provided with punch passing holes, and a lower template provided with a punching concave mold, serving as a main working part of the mold and matching with the upper stripper plate for punching the part. The semiautomatic punching mold further comprises a rotating mechanism; and in interval punching process of the part, the rotating mechanism drives the part to realize fixed-angle rotation. The invention further provides a punching method of the semiautomatic punching mold. The semiautomatic punching mold is provided with the rotating mechanism for driving the part to rotate through pulling a connecting rod, so that the purpose of punching holes in different positions is achieved, the problem of manually adjusting the angle of the part in the production process is prevented, the production efficiency is improved, and the safety in the production process is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of punching dies, and in particular relates to a semi-automatic punching die and a punching method thereof. Background technique [0002] Such as figure 1 As shown, for the products currently on the market that are densely arranged with long slits (even numbers) along the tangential direction, if all of them are punched out in one process, the lower template and the stripper plate are easily deformed and the strength cannot be guaranteed, and the production Larger equipment tonnage is required. If you want to punch out as figure 1 All the elongated holes of the parts shown must be blanked step by step while ensuring the strength and precision of the mold stripper plate and the lower template. If all the holes are punched four times, the whole punching process is carried out on a pair of molds. The specific interval punching process is as follows: figure 2 As shown, according to the traditional method, i...

Problems solved by technology

If all the holes are punched four times, the whole punching process is carried out on a pair of molds. The specific interval punching process is as follows: figure 2 As shown, according to the traditional method, it is necessary to manually adjust the placement angle of the workpiece continuously during the blanking process, which not only reduces the efficiency, but also increases the labor load of the production personnel, and the operation process is very dangerous
