Abstract

The invention relates to a thermocompression connection system, which belongs to the technical field of thermocompression connection equipment. Solve the problems of small connection area, low interface pressure and poor fastening of metal / plastic pipes. Including assembly and positioning guide rail, top, heating device, workpiece fixing support, rolling device positioning support, temperature setting device, screw bearing speed regulating positioning device and elastic rolling device, the assembly and positioning guide rail is installed in sequence with the top, workpiece fixing support The positioning support of the seat and the rolling device, the components to be connected are placed on the fixed support of the workpiece. The components to be connected are plastic pipes and metal pipes arranged inside and outside. The outside of the metal pipe is wrapped with a heating device. The heating device and the temperature setting device are electrically connected. Connection, the tip is in contact with the metal pipe, the positioning support of the rolling device is connected with the elastic rolling device, the elastic rolling device is connected with the screw bearing speed regulating positioning device, and the elastic rolling device extends into the plastic pipe and generates pressure on the plastic pipe. Improve the interface pressure of the metal / plastic pipe connection area, and the fastness is good.

Description

technical field [0001] The invention relates to a metal / plastic pipe thermocompression connection system, which belongs to the technical field of metal / plastic pipe thermocompression connection equipment. Background technique [0002] As an important way to achieve energy saving and emission reduction, the connection of dissimilar lightweight materials has been widely used in aerospace, rail transit, automobile and other fields. Due to their advantages of high specific strength and specific modulus, impact resistance, and good processing and molding, engineering plastics have become an important material for lightweight engineering that can replace metals. Due to cost constraints, it is still difficult to apply a single engineering plastic structure. Therefore, it is of great practical significance to realize the connection of metals and engineering plastics. The high-strength connection joints of metal and plastic and the diversified joint forms are also the key to realiz...
