Description of steel bar straight thread rolling machine
Steel bar straight thread rolling machine is a kind of steel bar processing machine widely used in the construction industry in recent years. It quickly and directly rolls the end of the steel bar at one time to produce cold hardening at the head of the threaded wire, thereby improving the strength and making the steel wire head the same as the base material. It consists of a frame, a clamping mechanism, a feed carriage, a reducer, a rolling thread head, a cooling system, and an electrical system.
Features of steel bar straight thread rolling machine
1. It can be rolled after stripping the ribs of the steel bar. The precision of the thread profile is very high, and the consistency of the diameter is also perfect;
2. It has a compact structure, and simple operation, and the thread processing speed is obviously faster than other equipment;
3. We call its rib stripping device "fool type", that is, it is easy to learn and understand, and the stability of the rib stripping size is very good;
4. The processing of the thread can be completed as long as the steel bar is clamped once, and the processing efficiency of the thread head is also very high;

Preparation before use of thread rolling machine
Preparation before processing
1. Connect the power cord and ground wire as required, and turn on the power. The power supply is a three-phase 380V—50Hz AC power supply. Please use an automatic switch with a leakage protection function to ensure personal safety.
2. Add enough soluble coolant (oily coolant is strictly prohibited) to the coolant tank.
Empty car test run
1. Turn on the power. Check whether the cooling water pump works normally.
2. Operate the button to check whether the electrical control system usually works.
Precautions for the use of steel bar straight thread rolling machine
1. The cooling liquid must use water-soluble emulsified cooling liquid, and oily cooling liquid is strictly prohibited, let alone ordinary lubricating oil.
2. Thread rolling is strictly prohibited without coolant.
3. The end of the steel bar to be processed should be flat and must be cut with a toothless saw. And within the 500mm length of the end, it should be round and straight, no bending is allowed, and it is not allowed to directly process the end of the gas cutting or cutting machine.
4. The feed should be uniform during the initial cutting, and do not advance sharply to prevent the blade from cracking.
5. Slideways and sliders should be cleaned and oiled regularly.
6. Iron filings should be cleaned up in time.
7. The cooling liquid tank is cleaned once every half month.
8. The reducer should be refueled regularly to maintain the specified oil level.
9. The rolling machine should be maintained regularly.
10. The casing of the machine tool must be reliably grounded before use.
