Description of Hydraulic Three-axis Thread Rolling Machine

The thread rolling machine is a multi-functional cold extrusion-forming machine tool. The thread rolling machine can process the thread, straight grain, and oblique grain rolling of the workpiece under the cold state within its rolling pressure range; straight teeth, helical teeth, and helical spline gears rolling; straightening, reducing, rolling, and various forming rolling. The machine has a safe and reliable electric-hydraulic execution and control system, which allows each working cycle to be selected from three modes: manual, semi-automatic, and automatic.
The thread rolling cold rolling process is an advanced non-cutting process, which can effectively improve the internal and surface quality of the workpiece. The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece. It is an efficient, energy-saving, low-consumption ideal process.

Technical Parameter

The reason and inspection of the thread rolling machine without reverse rotation

The front travel switch is broken (about 7000 times); the delay relay does not act;
The distance between the pressing block and the travel switch is not enough, the pressing block is not in place or is damaged and jammed;
The wiring is disconnected; whether the contacts are in poor contact or damaged;
Check whether the front limit contact is not in place, whether the closed point is open, whether the open point is closed, and whether the time relay open point is closed;
Check the limit position at the back of the machine, whether the closed point is disconnected, check the point of the line, whether the line is loose, poor contact, damaged, broken line, etc;
