Abstract

The invention relates to the technical field of steel strip machining, and discloses a punching device for steel strip machining. The punching device comprises a fixed block, wherein a fixed plate isfixedly connected to the bottom of the right side surface of the fixed block, and supporting legs are fixedly connected to the lower surfaces of the fixed block and the fixed plate; and a rotating groove is formed in the upper surface of the fixed plate, and the front surface and the back surface of the inner wall of the rotating groove are correspondingly and rotatably connected with the two endsof a first rotating rod. According to the punching device for steel strip machining, a first movable plate is enabled to move in an air cavity through a first movable rod and a first limiting rod, sothat the effect of changing the air pressure in the air cavity is achieved; and the change of the air pressure in the air cavity uses a second movable plate, a second limiting rod, a second movable rod and a connecting rod to fix a steel strip by a pressing plate, so that the steel strip is tightly attached to an arc-shaped groove, and when a punching knife is used for punching, the effect of reducing the deformation of the steel strip is achieved; and the damage of punching is reduced, and the yield of the steel strip is improved.

Description

technical field [0001] The invention relates to the technical field of steel strip processing, in particular to a punching device for steel strip processing. Background technique [0002] A measuring tape is a measuring tool commonly used in daily life, and it is one of the necessary tools in the family. Luban ruler, Fengshui ruler, and Wengong ruler also belong to steel tape measure. Steel tape measure is a common tool for construction and decoration. Steel tape measure can be divided into self-rolling tape measure, brake tape measure, and swing-roll tape measure. Other names of the steel tape are: steel tape, steel box ruler. The steel strip is the measuring part of the steel tape. When producing the steel strip, it is necessary to punch holes on the steel strip to facilitate fixing other parts on the steel strip. However, since the steel strip has a certain radian, and the steel strip is relatively thin, it is easy to slightly shake or deform when punching holes, causin...
