Description

technical field [0001] The invention relates to an inertial friction welding equipment, in particular to an equipment which can be used for radial inertial friction welding on the circumferential surface of a ring-shaped part and a cylindrical or tubular part. Background technique [0002] Inertial friction welding is a typical friction welding process. Conventional inertial friction welding is mainly used to realize the axial end face connection of weldments. The equipment used is usually called axial inertial friction welding machine. The equipment is mainly composed of mechanical system, hydraulic system , Electrical control system consists of three parts. The mechanical system refers to the bed of the main engine, which mainly includes the spindle box, rotary fixture, moving fixture, moving fixture cylinder, slide table, auxiliary stabilizing thrust cylinder and base. The main spindle box mainly includes the transmission spindle, rotary fixture cylinder and piston. The ...

Problems solved by technology

Since the oil cylinder and the transmission spindle are integrated in this structure, the oil cylinder is small and the piston moving distance is short, so it cannot realize the pressure adjustment of large flow during the rotation process; when it cannot meet the radial friction welding of large-diameter workpieces, the tooling clamping part radial The need for moving distance

[0007] 3) The special tooling device is clamped by the Mohs taper and is always in a free state. It cannot accurately position the annular weldment at any position in the tooling device, and it is easy to cause radial deformation of the pipe fittings; and the special tooling device needs to bear a large Axial force, complex structure, time-consuming and labor-intensive loading and unloading

[0008] 4) Radial inertial friction welding is carried out on the axial inertial friction welding machine. The radial pressure clamped on the annular weldment is implemented by the main thrust oil cylinder. When the main thrust oil cylinder pushes the special tooling device, the sliding table also follows Move forward, so there is a certain space at the rear end where the special tooling device is connected to the main shaft at the end of the moving fixture. During the welding process, the ends of the cylindrical and round pipe weldments are in a cantilever state, and the clamping torque of the rotating fixture cannot overcome the welding time. Influenced by welding torque, it is easy to cause surface strain of clamped cylindrical and circular tubular weldments
