The two step advancing pipe expanding machine introduction
The two step advancing pipe expanding machine for double oil cylinder two step propulsion pipe-maling machine modified.Because of the parallel double oil cylinder thrust in the center of a horizontal line, can not meet equipment expansion tube focus and balance, due to the expanding of the thrust focus down, will cause the oil cylinder rod and push board between the push rod bent upward on both ends of the equipment, make the rod of oil cylinder serious wear and tear, reduce the service life, in order to overcome the above weakness, four cylinder driving system expanding machine is designed.Make four cylinder thrust into the box type interchanged focus, improve the stability of equipment, increase the degree of freedom on the expanding machine equipment in operation, improve the working life of the equipment and the production efficiency. |
