Beginning friction welding 1-1.5 seconds, then carry out stablizing friction welding rear braking braking in 2-3 seconds with revolving speed 650rpm, pressure 45-60MPa,
It is subject to the upsetting force of 75-80MPa while brake, and keeps upsetting force 3-5 seconds.
It is convex that the utility model has the advantages that the utility model is struck out by the edge that press machine will pass through hole
Ring, and use special interconnecting piece, interconnecting piece includes the first cylinder, round estrade and the second cylinder being connected, when assembling, the
One cylinder and round estrade are inserted into shell through bulge loop, and the end face outside of the inner side end and bulge loop that make the second cylinder is in contact, thus
Convenient for the friction welding between the second cylinder and bulge loop.The utility model improves the second cylinder and bulge loop, the second cylinder and method
Gas brazing, carbon-dioxide arc welding are changed to friction welding by the welding manner between orchid, and energy consumption can be greatly reduced, and are reduced
The fraction defectives such as lack of penetration, stomata, crackle, incomplete fusion, improve because gas brazing cause welding position surface it is dirty, with residual
The phenomenon that object.Moreover, all welding do not generate smog and flare in whole preparation process, the work of worker is improved
Environment meets the requirement of environmental protection and safety in production.
