Features of Automatic Hydraulic Thread Rolling Machine
It is mainly used for processing various high-strength and precision workpiece threads, including ordinary threads, trapezoidal threads, modulus threads, through-wire threads, etc. It has the characteristics of reasonable design, strong processing capacity, and high efficiency.
Description of Hydraulic Automatic Hydraulic 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.

Common problems and solutions of thread rolling machine
1. The order of changing the inner gasket of the thread rolling
wheel: clockwise: thick, medium, and thin, and outer gasket, thin
and medium;
2. Fine-tune the size: After loosening the six inner angle screws
(or three outer hexagonal screws) behind the rolling wheel head,
use an adjustable wrench to fine-tune the size;
3. The length of wire adjustment: adjust the stopper distance on
the double-stroke switch;
4. Adjust the length of the leather: adjust and install the square
seat on the retracting shaft;
5. Car anti-wire
(1) The gaskets in the thread rolling wheel are installed in
reverse order
(2) Push button switch up
(3) Turn on the machine and peel the skin counterclockwise, press
the button switch on the back button to roll the thread clockwise,
and then return the thread counterclockwise
