Hole trimming device for punched parts

Abstract

The invention discloses a hole trimming device for punched parts, relates to the technical field of punched part machining, and aims to solve the problems that the inner surfaces of punched holes punched out of machined parts in the prior art are uneven and poor in smoothness after the machined parts are punched and machined, so that the actual use function of the workpieces is influenced. A fixing base is arranged at the bottom of the bearing case, radiating grids are arranged on the outer surface of the bearing case, a machining working platform is arranged on the upper portion of the bearing case, two side frame high fixing blocks are arranged on the upper portion of the machining working platform, a clamp control block is arranged above each side frame high fixing block, a clamp movingrail is arranged at the bottom of each clamp control block, a driving motor is arranged in the bearing case, a lifting bottom plate is arranged at the bottom of the driving motor, lifting rail rods are arranged on the two sides of the lifting bottom plate, and electric control assemblies are arranged on the two sides of the driving motor.

Description

technical field [0001] The invention relates to the technical field of stamping parts processing, in particular to a hole repairing device for stamping parts. Background technique [0002] Stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size. Stamping processing is With the help of the power of conventional or special stamping equipment, the sheet metal is directly subjected to deformation force and deformed in the mold, so as to obtain the production technology of product parts with certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing. According to the stamping processing temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the...
