The positioning assembly 32 and the bending assembly 33 are respectively installed on the pressing frame 31, and the positioning assembly 32 is located on one side of the bending assembly 33. The length of the positioning assembly 32 is longer than that of the bending assembly 33.

[0026] like Figure 3 and Figure 4As shown, the bending assembly 33 includes a pressure rod 331, a paddle 332 and a fixed block 333. The fixed block 333 is located on one side of the pressure rod 331 and is fixedly connected to the pressure rod 331. The paddle 332 is rotatably connected to the bottom of the fixed block 333 via an elastic member. The fixed block 333 is provided with a gap 001 for the paddle 332 to rotate, and the pressure rod 331 is provided with a contoured groove 002 for accommodating the paddle 332.

[0027] Specifically, the pressure rod 331 of the bending assembly 33 is installed on the pressing frame 31, the fixed block 333 is fixedly connected to the side end of the pressure rod 331, the end of the pressure rod 331 is located below the fixed block 333, and the paddle 332 is rotatably connected to the fixed block 333 through a rotating shaft, and an elastic member is provided on the rotating shaft. When the paddle 332 bends the claw 5, the paddle 332 is subjected to force, the upper half of the paddle 332 rotates in the gap 001 of the fixed block 333, and the bottom of the paddle 332 rotates into the contoured groove 002 of the pressure rod 331; when the paddle 332 is not subjected to force, it can be reset under the action of the force of the elastic member. Among them, the elastic member is a torsion spring.

[0028] The driving component 2 drives the pressing frame 31 to drive the positioning component 32 and the bending component 33 to move toward the product. During the movement, the positioning component 32 first positions the product and continues to move downward. The paddle 332 of the bending component 33 bends the claw 5 on the product toward the pressure rod 331 and continues to move downward. Finally, the pressure rod 331 flattens and presses the bent claw 5 onto the product.

[0029] In the above structure, the product is positioned by setting the positioning component 32, and then the claws 5 on the product are bent and flattened by the bending component 33.

[0031] Specifically, the connecting rod 322 is slidably matched with the pressing frame 31, and the driving assembly 2 drives the positioning assembly 32 to move downward, so that the pressing head 321 positions the product. When positioning, the pressing head 321 is subjected to force to compress the spring 323, and the spring 323 acts as a buffer for the pressing head 321. When the pressing head 321 is separated from the product, it is reset under the action of the spring 323. This arrangement is convenient for fixing the product.

[0032] like Figure 3 and Figure 4 As shown, in one embodiment, the bottom of the paddle 332 of the claw bending mechanism is provided with an inclined arc, and the paddle 332 is used to bend the claw 5 of the product.

[0033] like Figure 3 and Figure 4 As shown, in one embodiment, the bottom of the pressure rod 331 of the claw bending mechanism is set as a flush end, and the pressure rod 331 is used to flatten the bent claw 5. The flush end of the pressure rod 331 is conducive to compacting and flattening the bent claw 5.

[0035] Specifically, the motor 21 drives the screw mechanism 22 to rotate, and the driving end of the screw mechanism 22 drives the pressing frame 31 to move up and down along the support frame 1, and the pressing frame 31 drives the positioning assembly 32 and the bending assembly 33 to move up and down. This arrangement facilitates driving the positioning assembly 32 and the bending assembly 33 to position and bend the product.

When the equipment is not working, the cylinder 41 drives the fixing head 42 to fix the driving end of the screw mechanism 22 to prevent the screw mechanism 22 from loosening and damaging the positioning assembly 32 and the bending assembly 33.
