AI Technical Summary
In existing welding strip flattening devices, the piston rod strokes of the double-chamber single-acting cylinders are not synchronized, resulting in inconsistent welding strip flattening accuracy, and the equipment is prone to wear and tear, leading to high maintenance costs.
The dual-chamber single-acting cylinder uses a magnetic locking pair linked with a pressure sensor. The piston rod is locked before the air chamber pressure is equalized through the magnetic structure. Combined with rubber gasket buffer and multi-point pressure sensing, it ensures that the piston rod moves down synchronously and avoids asynchronous stroke.
It improves the forming consistency of weld strip flattening and the long-term stability of the equipment, and reduces wear and maintenance costs.
