How to eliminate the failure of the motor of the automatic hydraulic pipe bending machine?

2020-06-15

Fully automatic hydraulic pipe bending machine is a newly developed machine in recent years. It can be said that my country's active machinery profession is developing rapidly, and the horizontal unevenness of active machine tool development, its active machine tool functional components have played an extremely important effect.

Machine tool functional components are one of the most important parts of active machine tools. Chinese enterprises have always attached great importance to their development. In recent years, China's active machine tool functional components have made great progress. However, China's active machine tool functional components have always been in "Heavy host, light supporting", "Heavy ocean light soil" such as the endless progress and difficult growth. In particular, the high price of imported functional components has led to the high cost of domestic mainframe products, which directly weakened the competitiveness of domestic machine tools and imported machine tools. Independent intellectual property rights have entered the hearts of producers, focusing on research and development is to improve profits.

The cause of the fault of the motor of the automatic hydraulic pipe bender: when the pipe bender motor is repaired, the number of stator winding turns is reduced too much; the power supply voltage is too high; the Y-connected pipe bender motor motor is mistakenly connected to Δ; the pipe bender motor motor is being assembled. When the rotor is reversed, the stator core is misaligned and the useful length is shortened; the air gap is too large or uneven; when the old winding is overhauled, the thermal dismantling method is improper and the core is burned.

Fault removal: Rewind the stator winding and restore the correct number of turns; try to restore the rated voltage; change the motor of the automatic hydraulic pipe bender to Y; reassemble; replace the new rotor or adjust the air gap; repair the iron core or recalculate the winding, appropriate Increase the number of turns.

High-speed, high-precision, five-axis linkage, and compound machine tools are the main directions for the development of machine tools in the future. Machine tool functional components must be developed around this theme in order to meet the needs of machine tool manufacturers. It can be said that self-innovation has always been the direction of the manufacturer's best efforts, and development is the manufacturer's goal. With such a concept, my country's active occupation must achieve greater competitiveness in the world.
