How to deal with the broken tooth roller and how to maintain it?

Tooth RollerIt is a multi-functional cold rolling forming machine tool. It is mainly divided into three types: manual, semi-automatic, and fully automatic. As a commonly used processing equipment, its maintenance cost is high, the maintenance requirements are relatively complex, the dimensions are stable, and the accuracy is high. It can be produced according to the instrument, precision screw, and fixed strip rolling formula. The fixed size allows vibration plates, fully automatic workpieces, rolling formulas suitable for processing length, and a 3-axis machine for processing hollow pipe threads. It is specially used for the design of pipe parts. It has 3-angle support to determine the roundness, high accuracy, concentricity and verticality of the workpiece. The following will introduce the troubleshooting of common tooth rollers, daily maintenance content and regulations:

1. Reasons for the tooth roller not starting:

1) Open empty, and the reverse direction always stops at close; the power supply is missing.

2) The heat protector plays a protective role and the insurance is burned out.

3) The wiring is off and the transformer is burned out.

4) Control whether the line contacts are damaged or poorly contacted.

5) Check whether the stop start button is disconnected and loose; whether the button contacts are good.

6) Check whether the limit contacts in front of the equipment are good, whether the contacts, lines and insurance are damaged (the insurance for the transformer entering and exiting).

2. The feeding of the movable wheel rod is slow.

The slow feeding speed of the movable wheel rod may be caused by damage to the rubber ring sealed by the cylinder, or it may be caused by leakage in the pipeline. Replacing the rubber ring or repairing the pipeline can solve the problem.

3. The parts are not familiar with the processing during rolling.

When rolling the machine, the processing parts may not be rolled well by the tooth rod speed or the feeding speed is too fast. Another possibility is that the rolling pressure is too large. According to the corresponding situation, the high-speed wheel rod speed is slowed down and the rolling pressure is reduced.

4. The pressure gauge pointer vibrates.

There are many reasons for the vibration of the pressure gauge pointer of the tooth roller machine. The common one is that the oil-sucking filter element is blocked, so just take it off and clean it before installing it.

5. The solenoid valve does not operate.

There are many reasons why the solenoid valve of the tooth roller does not operate, which may be the burning of the electrical rectifier block, the transformer, or the fuse tube is burned, and another possibility is that the valve is stuck, causing the solenoid valve to not work. The solution is to replace the corresponding components. If the valve is stuck, please clean the valve.

Daily maintenance content of tooth roller:

1. It is not allowed to tap or straighten the workpiece on the chucks or bed guides, and tools or workpieces are not allowed to be placed on the bed surface.

2. Before starting, check whether the workpieces on the machine tool are clamped. Place the handles of each gear changer in the low speed gear to prevent the lathe from being damaged due to sudden impact during driving. After starting. The spindle should be idle at a low speed of 1-2mm, so that the lubricating oil should be evenly distributed to all places (more important in winter), and can only work after the lathe is running normally.

3. When turning cast iron and chip-like workpieces, the lubricating oil on the guide rail should be wiped off to avoid damaging the guide rail surface.

4. When the spindle needs to change speed during the operation of the tooth roller, the machine must be stopped first. The position of the feed box handle must be changed at low speed.

5. When using cutting fluid, lubricating oil must be applied to the lathe guide rail. The cutting fluid in the cutting fluid pump should be replaced regularly.

6. In order to maintain the accuracy of the lead screw, the automatic tooth rolling machine shall not use the lead screw for automatic cutting except for the threads.

7. When fully automatic tooth roller clamps heavier workpieces, wooden boards should be used to protect the bed surface. If the workpiece is not removed when you get off work, jacks should be used to support it.

8. After get off work, the chips and cutting fluid on the lathe and around the lathe should be removed. After cleaning, lubricating oil should be added to the surface of the guide rail as required, tail seat sleeve and lead screw. The lubrication of nuts can be refueled once per shift. Since the speed of the long screw and light rod is high and the lubrication conditions are poor, you must pay attention to refueling every shift, and then shake the bed saddle to the rear end of the car and turn off the power.

9. After the turning tool is worn, sharpen it in time. Continuing cutting with a blunt knife will increase the lathe load and even damage the machine tool.
