Three Dies Thread Rolling Machine

It consists of six main parts: the rolling roller, the machine body, the reducer, the clamping table, the coolant system, the motor housing, and other smaller accessories. The overall design of the machine body gives it a simple and easy-to-move appearance. It can process threads between M16 and M40, with various thread patterns. The type of rolling roller depends on the workpiece being processed, as thread rolling machines are available in three-axis and two-axis models; be careful not to choose the wrong one. The reducer helps to gradually increase and decrease the speed of the workpiece during the thread rolling process. The coolant primarily lubricates and protects the processed parts, as dry rolling is impossible when processing metal workpieces like steel pipes. The clamping table is used to hold the workpiece in place. The motor housing houses the main control circuitry of the entire machine, facilitating maintenance in case of problems.

 

 

 

 

 

Troubleshooting methods for some common problems with three dies thread rolling machine

1. Threading with the machine running counterclockwise: Start the machine, strip the outer shims counterclockwise, roll the threads, and then unroll them clockwise.

2. Sequence for changing the inner shims of the thread rolling wheel: Clockwise: thick shims for the middle and thinner outer shims, thinner outer shims for the middle and thicker outer shims.

3. Fine-tuning the dimensions: Loosen the six inner screws (or three outer hex screws) behind the thread rolling wheel head, and then fine-tune the dimensions with an adjustable wrench.

4. Adjusting the thread length: Adjust the distance between the stops on the double-stroke switch.

5. Adjusting the length of the stripper: Adjust the square seat on the retraction shaft.

6. Threading with the machine running counterclockwise:

(1) The shims inside the thread rolling wheel are installed in the wrong order.

(2) Turn the button switch upwards.

(3) Start the machine, strip the outer shims counterclockwise, press the back button on the button switch, roll the threads clockwise, and then unroll them counterclockwise.
