Operation and advantages of the tooth roller

The emergence of the tooth rolling machine has brought good results to some industries. Although the screws are widely used, they still need to pay attention to their operation. Let’s see how they operate.
1. The material rack and material trough should be straight, aligned with the center line of the guide cylinder, straightening cylinder and the lower cutting tool hole.
2. Roll the flywheel with your hands, check the transmission tissue and working equipment, adjust the gaps, tighten the bolts, and after confirming that they are normal, start the empty work, check that the bearing should be free of abnormal noise, and the gear meshing is excellent, and can only operate after working normally.
3. Select the appropriate straightening block and transmission speed according to the diameter of the straightening steel bar. Only after the commissioning is qualified can the material be fed.
4. No feeding of materials is allowed before the straightening block is fixed and the protective cover is covered. It is prohibited to open each part of the protective cover and adjust the gap during operation.
5. After the steel bar is fed in, it is necessary to keep a certain distance between the hand and the pulling wheel and do not be close.
6. Before feeding, the unstandard material head should be cut off. A 1m-long steel pipe should be installed in front of the guide barrel. If the steel bars need to pass through the steel pipe first and then fed into the guide hole at the straightening front end.

7. After operation, the straightening block of the straightening cylinder should be loosened and returned to its original position. It is necessary to return to the position of the pre-pressing spring together.
8. Those who use electric motors and hydraulics as power and winches as auxiliary machines shall be carried out in accordance with relevant regulations.
9. It is necessary that the mechanical equipment be solid and stable and maintain a horizontal position. Fixed machinery should have a reliable foundation, and the walking wheel should be tightly wedged when operating the mobile machinery.
10. Outdoor operations should be equipped with a shed, and there should be a site for stacking materials and semi-products next to the machine.
11. When processing longer steel bars, there should be a dedicated person to help and follow the instructions of the operator and not push and pull arbitrarily.
12. After operation, the products should be stacked, the site should be cleaned, the power supply should be blocked, and the power switch box should be locked.
Advantages of tooth roller:
1. The rolling mold has a long life;
2. High requirements for blank dimensional accuracy;
3. The surface roughness is less than turning, milling and grinding;
4. The processed products have good straightness, good concentricity and high accuracy;
5. The surface of the rolled thread can improve strength and hardness due to cold hardening;
6. The accuracy and hardness of rolling molds are also high, making molds difficult;
7. High material utilization rate; productivity increases exponentially than cutting and processing, and is easy to complete automation;
8. The tooth rolling process is attributed to plastic deformation, which is different from cutting processing such as automatic lathes, and there are no iron chips.
