Abstract

The invention discloses a friction welding device with a preheating function, and relates to the technical field of friction welding. The friction welding device with the preheating function comprisesa base, wherein a fixing table is arranged at the top end of the base; a motor and a fixing block are arranged at the top end of the fixing table; the fixing block is close to the position of the output end of the motor; and the inner wall of the fixing block is sleeved with a bearing. According to the invention, the preheating function is achieved through arrangement for a preheating table, a second electric push rod, a preheating box, an induction coil, a connecting hole, a telescopic block, a spring and a transformer, an alternating current is led in through the induction coil, and therefore an alternating magnetic field is formed, and materials to be welded generate vortexes to be heated through the magnetic field; and the height of the induction coil can be adjusted through the second electric push rod, the induction coil is configured to be in a semi-arc shape, and the materials can be conveniently placed and taken out through the semi-arc shape.

Description

technical field [0001] The invention relates to the technical field of friction welding, in particular to a friction welding device with a preheating function. 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 material undergoes pla...
