Two step four cylinder pipe expanding machine introduction:
The device for four oil cylinder two step pipe expanding machine modified.From 630 to 1020 more than large diameter thick wall steel pipe expansion system, must make the device itself plate is pushing plate steel pipe via increased, and finally a straight steel tube expansion.Via at least from 750 ~ 750 above, because of the parallel double oil cylinder thrust in the center of a horizontal line, can not meet equipment expansion tube focus and balance.For expanding the thrust focus down, will cause the oil cylinder rod and putting up between the two push plate bending equipment, make the oil cylinder rod serious wear and tear, reduce the service life, in order to overcome the above weakness, four cylinder driving system expanding machine is designed.Turn interchanged four cylinder thrust into the box type focus, improve the stability of pipe expanding machine, increase the degree of freedom on the pipe expanding machine in operation, improve the working life of the equipment and the production efficiency. |
