Abstract

The invention discloses a cooling device for induction welding of thermoplastic composite materials. The cooling device comprises a pressurizing device, a cooling liquid circulating device and a computer control center, wherein the cooling liquid circulating device comprises a liquid cooling device, a cooling liquid storage device, a circulating pump, a heat preservation conveying pipe and pipe joints; the liquid cooling device is arranged in the pressurizing device, and temperature sensors are arranged at the outer bottom of the pressurizing device; and the computer control center is connected with the temperature sensors and the circulating pump to adaptively adjust the flow velocity of cooling liquid. The problem that welding points cannot be cooled at the same time when pressurized inthe induction welding process of the thermoplastic composite materials is solved, meanwhile, rapid selective cooling is realized, so that the use is convenient, the operation is easy and convenient, the working efficiency is high, and time can be saved.

Description

technical field [0001] The invention belongs to the field of induction welding of composite materials, in particular to a cooling device for induction welding of thermoplastic composite materials. Background technique [0002] In recent years, thermoplastic composites have been widely used in aerospace and automotive fields. Subsequently, the connection technology of thermoplastic composites is particularly important. Joining thermoplastic composites by mechanical riveting or adhesive bonding is complex and costly. Therefore, induction welding, which has been widely used in metallic materials for a century, was proposed for thermoplastic matrix composites. [0003] Induction welding is a special welding process, which generates a high-frequency electromagnetic field by an induction coil, and the welding induction material placed at the welding interface generates eddy current and heats up, so as to achieve the purpose of welding. When welding non-conductive fiber-reinforc...
