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.

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;
