Description

Technical Field

[0001] The utility model relates to the technical field of stamping and forming, in particular to a stamping and forming device for a stud bolt processing die. Background Art

[0002] Stud bolts, also called stud screws or studs, are used for the fixed connection of mechanical connections. Stud bolts have threads on both ends, and the screw in the middle can be thick or thin. They are generally used in mining machinery, bridges and large buildings. During the processing of stud bolts, a stamping forming device is required to stamp their ends.

[0003] The existing stamping forming mechanism clamps and fixes the stud bolts during use. The currently used stud bolt processing mold forming device uses a milling cutter to mill out the round head of the stud bolt. However, the accuracy cannot be well controlled when using the milling cutter, resulting in insufficient precision.

[0004] In order to improve the processing accuracy, after searching, the utility model patent with publication number CN209077515U in the prior art discloses a double-headed bolt processing mold stamping forming device, including a base, a body is fixedly arranged on the upper surface of the base, a first groove is opened inside the body, a motor is fixedly arranged inside the first groove, a second groove is opened on the upper surface of the body, the top end of the motor passes through the body and is arranged inside the second groove, and a stamping disk is fixedly arranged on the upper end of the body inside the second groove.
