AI Technical Summary
Existing spring shearing devices are prone to spring jumping out during the shearing process, and require multiple cuts, resulting in low shearing efficiency.
The system employs hydraulic and pneumatic push rods in conjunction with a limiting insert and a semi-circular limiting cover to wrap the spring and cut it off in one go with a blade, preventing the spring from flying off and improving cutting efficiency.
This achieves efficient one-time cutting of the spring, preventing it from flying off and improving cutting efficiency.
