Abstract

The invention relates to the technical field of friction welding, in particular to a friction welding machine capable of rolling and leveling a workpiece. The friction welding machine comprises a mounting frame mechanism, wherein the mounting frame mechanism comprises a base, a first mounting frame is fixed to the top end of the base, a second mounting frame is fixed to the position, located at one side of the first mounting frame, of the top end of the base, and a third mounting frame is fixed to the position, located at one side of the second mounting frame, of the top end of the base; and adriving motor is installed at the top end of the third mounting frame, the output end of the driving motor is connected with a second clamping mechanism, and an eccentric mechanism is connected to the position, located on the outer wall of the second clamping mechanism, of the top end of the second mounting frame. According to the friction welding machine, through the arrangement of a connectingmechanism and a grinding mechanism, a grinding head can be rapidly mounted or dismounted through the connecting mechanism, the process is convenient, and after welding is completed through the grinding mechanism, a weld joint can be rapidly ground, the purpose of rolling leveling after welding is completed is achieved, the machining difficulty needed by the workpiece is reduced, and therefore theproduction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of friction welding, in particular to a friction welding machine capable of rolling and leveling workpieces. Background technique [0002] Friction welding refers to the method of using the heat generated by the friction of the contact surface of the workpiece as the heat source to cause the workpiece to undergo plastic deformation under pressure. Under the action of pressure, it is under the action of constant or increasing pressure and torque. The relative movement between the contact end surfaces generates frictional heat and plastic deformation heat on the friction surface and its surrounding area, so that the temperature of the nearby area rises to a temperature range close to but generally lower than the melting point, and the deformation resistance of the material decreases and the plasticity improves. The oxide film on the interface is broken, and under the action of the upsetting pressure, the mater...

Problems solved by technology

[0003] However, the existing friction welding device cannot effectively grind the inner wall of the round pipe. After the welding is completed, other methods are used to weld the weld seam position of the pipe for rolling leveling. There are many operating steps, resulting in higher leveling costs. , the effect of leveling after welding cannot be achieved; at the same time, the existing clamping mechanism cannot quickly adapt to different pipes, resulting in low applicability
