Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and specifically to a stamping positioning device. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. It is widely used in the field of machining.

[0003] Currently, the positioning of stamping dies during stamping production is generally ensured by using locating pins and limit pins. However, positioning the die base solely by locating pins is prone to displacement during stamping production, making it difficult to guarantee positioning accuracy and resulting in poor stamping precision. Furthermore, after the die base shifts, the locating pins directly contacting the locating pin base can easily damage the base, affecting the processing of stamped parts, causing discontinuous stamping, and reducing stamping efficiency.

[0004] Based on this, the present invention designs a stamping positioning device to solve the above problems. Utility Model Content
