Adjustable drawing device for preventing arching of material strip in stamping die

Abstract

The invention belongs to the technical field of stamping, and particularly relates to an adjustable drawing device for preventing arching of a material strip in a stamping die. The adjustable drawingdevice comprises a base, electric push rods, a lifting plate, an electric drive module and the like; and the two electric push rods are symmetrically installed at the upper end of the base, and the lifting plate is installed at the upper ends of the two electric push rods. According to the drawing device, the positions of meshing points of a gear and a tooth plate can be adjusted according to thedistance between every two adjacent stamping holes on the material strip, so that it is ensured that when the device runs, the rotating gear drives the tooth plate to run to the extreme position, anda next stamping hole adjacent to the stamping hole matched with a clamping block right reaches the position of the clamping block before movement. The adjustable drawing device effectively avoids thearching phenomenon of the material strip in the stamping process, smooth stamping of the stamping die on the material strip is facilitated, and the stamping work efficiency and the maximum utilizationrate of the material strip are improved.

Description

technical field [0001] The invention belongs to the technical field of stamping, and in particular relates to an adjustable material pulling device for preventing material belts in a stamping die from arching. Background technique [0002] Stamping process is a metal processing method, which is based on the plastic deformation of metal, using stamping dies and stamping equipment to exert pressure on the sheet, so that the sheet is plastically deformed and separated, so as to obtain a certain shape, size and performance. stamping parts. Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of large batches of parts and products, which is convenient for mechanization and automation, and effectively improves production efficiency. However, in the traditional stamping production process, if the sheet to be punched is in the shape of a long strip, the phenomenon of arching in the middle ...

AI Technical Summary

Problems solved by technology

However, in the traditional stamping production process, if the sheet to be punched is in the shape of a long strip, the phenomenon of arching in the middle is likely to occur during the stamping process, which is not conducive to the continuous stamping of the strip-shaped sheet; in order to overcome the There is a phenomenon of tape arching, it is necessary to design a pulling device that can eliminate the arching of the tape to the greatest extent
