Abstract

The invention discloses a device and method for quickly repairing thermoplastic plastic automobile parts. The device comprises a casing and a cup; a fan blade driven by a motor, a disk-shaped heatingwire assembly and a labyrinth cover are arranged in the casing; and air holes are used for air circulation and heat transferring. When the cup covers an area to be shaped, an inner part of the casingis divided into an upper sealing cavity and a lower sealing cavity with the position where the fan blade is located as the boundary; and a first valve is installed on the portion, corresponding to theupper sealing cavity, of the casing, and a second valve is mounted on the portion, corresponding to the lower sealing cavity, of the casing. Rapid maintenance of the automobile parts is achieved by controlling forward and reverse rotation of the motor, opening or closing of the valves and on or off of resistance wires. The device can work directly on the surfaces of the thermoplastic plastic automobile parts without detaching automobile body coverage pieces, and the whole repair process is automatic; deformed standard parts can be repaired without replacing the coverage pieces, the structureis simple, the operation is simple, the efficiency is high, and the device can greatly save human effort.

Description

technical field [0001] The invention relates to a repair tool for thermoplastic auto parts, in particular to a rapid repair device and method for thermoplastic auto parts; it is suitable for rapid repair of thermoplastic auto covers after slight collision and deformation. Background technique [0002] At present, thermoplastics, as a widely used engineering plastic material, are gradually being used in various fields such as automobiles, construction engineering, and medical equipment. When thermoplastics are used to make automotive parts, there are no technical guidelines for the repair of slight dents and deformations that are widely used. For example, for the dented deformation of the bumper of a car, the bumper is generally replaced or disassembled first, and the sunken part is heated with a heater until the material melts and softens, and then the raised part is pressed back from the inside of the bumper with a straight awl. However, secondary damage to the bumper may ...
