Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a stamping positioning device. Background Art

[0002] Stamping is a forming processing method that relies on a press and a die to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. When stamping automotive parts, in order to ensure product quality and process stability, the workpiece will be positioned. Currently, when positioning parts, most of them are driven by a screw to move the pressure plate downward to press the workpiece and position the parts. However, the screw is driven by manpower when rotating, which not only causes high labor intensity for workers, but also slow manual rotation of the screw, resulting in low efficiency in part fixation.

[0003] As disclosed in application number 202122878127.1, a positioning and stamping device for automobile parts production includes a base plate, a shell is fixedly installed on the top of the base plate, a first slide rail and a bidirectional screw are arranged inside the shell, an L-shaped slider is slidably arranged on the first slide rail, and a first clamping plate is installed on the right side of the L-shaped slider through a mounting plate, a bracket is fixedly installed on the top of the mounting plate, a first screw is arranged on the bracket, and a second clamping plate is fixedly installed on the bottom of the first screw, a stamping table is arranged on the top of the shell, a top plate is fixedly installed on the top of the base plate through a support rod, a second screw and a second slide rail are arranged at the bottom of the top plate, a lifting plate is slidably arranged on the second slide rail, and a stamping device is fixedly installed on the lifting plate. The utility model improves the precision of part stamping by performing multiple limiting and fixing on the stamping parts. At the same time, the relatively automatic work process improves the production efficiency and also improves the safety in production. Although the patent can perform multiple limiting and fixing, the patent fixes the workpiece by manually driving the screw, which leads to heavy labor for workers and slow workpiece fixing speed, which affects the stamping efficiency of the parts and cannot meet the factory's demand for mass part stamping.
