Description

A positioning and clamping structure for stamping and processing of automobile connecting plate

technical field

The utility model relates to the technical field of punching processing, in particular to a positioning clamping structure for punching processing of an automobile connecting plate.

Background technique

Stamping is to rely on presses and molds to apply external force to plates, strips, pipes and profiles, etc., to cause plastic deformation or separation, so as to obtain workpieces of required shape and size. Based on the power of conventional or special stamping equipment, the sheet is directly subjected to deformation force and deformed in the mold.

Existing stamping devices generally use positioning stoppers to position the sheet. Due to the flexibility of the sheet, it is easy to move in the stamping die when placing the sheet, resulting in misalignment. This method makes the sheet easy to slip during the stamping process, resulting in The processing accuracy and processing quality are not up to standard, which seriously delays the production schedule and greatly increases the production cost.
