Two step pipe expanding machine propulsion is interchanged in view of the lack of large diameter seamless steel tube production and design specification is not complete.The introduction of pipe expanding machine:
Users should bring along their own:
1, cooling circulating water system (pool), water pump, water divider, fluctuation conduit.
2, pipe expanding machine about steel pipe storage bench.
3, pipe expanding machine with the hydraulic oil: L - HM anti-wear hydraulic oil 32 # ~ 100 # 46 # (recommended).
4, the workshop equipment connecting wire and cable, the specification see equipment operating instructions.
5, according to production needs, can further purchasing medium frequency induction heating coil, tube expanding mold core.
The pipe expanding machine working principle: the raw materials will be prepared steel pipe set in the expansion pipe mould core head, add the medium frequency induction hot line trap at the end of raw material of steel pipe and expanding mold core head, fixed expansion pipe mould core head tie rod end, open the cooling water pump, open the medium frequency power supply, the raw materials are heated to 800 ℃ and the expanding die for steel tube, open the push system machine can start push the expansion pipe.
