[0019] 2. When the upsetting punch moves downward in the present invention, the thinnest part of the workpiece undergoes upsetting deformation in the two upsetting grooves; when the two linear electric cylinders drive the movable support frame to move forward, the linkage push frame pushes the circular force-bearing rod upward, causing the two forming modules to move upward. Under the action of the eight positioning link rods, the two forming modules can open to both sides, facilitating the installation and disassembly of the workpiece.

[0020] In addition, when the two linear electric cylinders drive the movable support frame to move backward, the circular force-bearing rod moves downward under the action of gravity, and the two forming modules can close inward under the action of the eight positioning link rods, enabling the two upsetting grooves to automatically contact the workpiece.

[0021] 3. When the upsetting punch moves downward in the present invention, the upsetting punch can drive the movable lifting frame to move downward simultaneously, ensuring that before the upsetting punch contacts the workpiece, a small part of the bottom of the four positioning insertion rods can be automatically inserted into the four positioning slots, playing a limiting role on the two forming modules, avoiding the generation of gaps between the two forming modules, and ensuring the upsetting accuracy of the workpiece.

[0022] In addition, when the positions of the two forming modules change after closing, one or more of the positioning insertion rods cannot be smoothly inserted into the corresponding positioning slots, indicating that the workpiece after local upsetting does not meet the processing requirements.

[0023] In addition, when one or more of the control switches are in the pressed state, the alarm can work, capable of reminding that the workpiece after local upsetting does not meet the processing requirements, facilitating the staff to adjust or replace the two forming modules in a timely manner, and ensuring the local upsetting accuracy of the workpiece.
