The core working principle of wire winding hydraulic press
1、 Basic Core Logic
Using high-strength steel wire with multiple layers of prestressed pre tension to wrap the fuselage frame, keeping the frame in a compressed state at all times; When the equipment is pressed, pre pressure is used to counteract the tensile stress generated by the load, avoiding frame tensile deformation and cracking from the root, and achieving large tonnage, high rigidity precision pressing.
2、 Step by step detailed principle
1. Prefabricated prestressing (static prestressing stage)
The upper crossbeam, lower crossbeam, and column cylinder of the host are wrapped and bound in multiple layers of cross continuous high-strength steel wire with ultra-high tension;
The precise control of tension during the winding process generates elastic compression prestress in the wrapped steel structure, which is equivalent to tightly holding the entire machine and pre storing a huge compressive force.
2. Hydraulic power loading (forming stage)
The hydraulic system drives the main oil cylinder to descend, exerting tremendous pressure on the mold and workpiece;
At this point, the reaction force of the workpiece will attempt to stretch the upper and lower crossbeams, causing the frame to be stretched.
3. Stress Offset Balance (Key Core)
The tensile stress generated by work is counteracted by the pre compression stress generated by the previous steel wire manufacturing;
The final frame of the entire machine has almost zero stretching and slight deformation, ensuring the parallelism of the tabletop and stable compression accuracy.
4. Pressure holding and return reset
The precision hydraulic control system completes voltage stabilization and maintenance, as well as thin plate shaping; At the end of the process, the oil cylinder is depressurized and returned, and the frame rebounds back to its initial state, repeating the operation in a loop.
