Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing auxiliary equipment, in particular to a fixing device for automobile parts die stamping. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to produce plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with reinforcing ribs, ribs, undulations or flanging that are difficult to manufacture by other methods, in order to improve their rigidity.

[0003] In the process of automobile parts production, a fixing device for stamping automobile parts molds is needed. The Chinese utility model patent with the announcement number CN211539246U discloses a stamping mold fixing mechanism for automobile parts processing, including a support frame and a hanger fixedly installed on the support frame. The left and right sides of the bottom of the top plate of the support frame are fixedly connected with connecting plates. The opposite sides of the two connecting plates are rotatably connected with threaded barrels through bearings. The inner surfaces of the left and right sides of the threaded barrel are threadedly connected with retractable threaded rods. The threads of the two retractable threaded rods are completely opposite. The end of the retractable threaded rod away from the threaded barrel is fixedly connected to a limited fork frame. The utility model utilizes the cooperation of the threaded barrel and the retractable threaded column to retract and release from the punch head to both sides. After adjusting the size of the limit fork frame according to the size of the mold, the mold is directly placed on the limit fork frame. Tightening the clamping threaded rod can make the clamping plate clamp the mold.
