Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a positioning mechanism for stamping molds. Background Technology

[0002] A stamping die is a specialized tool used in stamping processes. It is installed on stamping equipment to apply pressure to sheet metal, causing plastic deformation or separation to obtain stamped parts of the desired shape and size. A stamping die typically consists of two parts: an upper die mounted on the slide of the stamping equipment, and a lower die mounted on the worktable. The working parts of the die include punches, dies, and punch-die combinations, which work together to achieve processes such as blanking, bending, stretching, and forming of the sheet metal. Stamping dies are widely used in the automotive, home appliance, electronics, and aerospace industries, and are an indispensable key process equipment in stamping production.

[0003] Authorization announcement number CN217095367U discloses a stamping part positioning device for stamping dies. The technical solution is as follows: "It includes a positioning platform, a first adjusting plate, and a second adjusting plate. The first adjusting plate is located below the positioning platform, and the second adjusting plate is located below the first adjusting plate. A first adjusting mechanism is installed between the positioning platform and the first adjusting plate, and a second adjusting mechanism is installed between the first adjusting plate and the second adjusting plate." The beneficial effects are: the stamping part is centered using four electric cylinders; the fixing method is simple; it is suitable for positioning stamping parts of various sizes; no auxiliary parts are required during positioning; the stamping part is easy to assemble and disassemble; and the positioning stability is good.

[0004] The above technical solution has the following drawbacks. First, fixing the stamped part with four electric cylinders not only increases the overall cost of use, but also makes the maintenance and upkeep of the electric cylinders more complicated, increasing the maintenance cost of the equipment. Second, the sliding range of the first and second slide rails in the device is small, which limits the size and shape of the stamped part and makes it difficult to meet diverse production needs. Therefore, a positioning mechanism for stamped part mold is proposed to solve the problems mentioned above. Utility Model Content
