Description

Welding head of macromolecule diffusion welding equipment Technical Field The utility model belongs to the technical field of diffusion welding, and particularly relates to a welding head of polymer diffusion welding equipment. Background The polymer diffusion welding is also called as diffusion welding, and refers to a solid state welding method in which a workpiece is pressurized at a high temperature, but no visible deformation or relative movement occurs. The diffusion welder is used for press-welding and forming the end part of a workpiece (copper/aluminum foil flexible row). The prior art generally adopts the electric resistance welding principle that a pressing device presses a workpiece between an upper graphite electrode (welding head) and a lower graphite electrode (welding head), and a large current is conducted between the two electrodes, so that the workpiece is heated to the melting point temperature of 60-80% of a base metal in a conductive way, the temperature is kept, the pressure is kept, and all layers of foils are pressed and welded together. Most of the existing diffusion welding heads use graphite, but the graphite is worn after multiple times of welding, so that the service life of the graphite welding heads is shortened. Disclosure of utility model The utility model aims to provide a welding head of polymer diffusion welding equipment so as to solve the problems in the background technology. In order to achieve the purpose, the welding head of the polymer diffusion welding equipment comprises a copper seat and a graphite welding head, wherein the copper seat is fixedly connected with the graphite welding head, a metal plate is fixedly arranged on the graphite welding head, and a coil is wound on the outer side of the graphite welding head. Preferably, the copper seat is fixedly provided with an insulating block, the insulating block is provided with a through hole and an assembly groove arranged around the through hole, the graphite welding head penetrates through the through hole, and the assembly groove is fixedly provided with the coil. Preferably, the insulating block is made of asbestos or alumina ceramics. Preferably, the wire of the coil is a copper tube. Preferably, a heat insulating layer is arranged between the copper seat and the graphite welding head. Preferably, the metal plate is made of tungsten alloy. Preferably, the graphite welding head is fixedly mounted on the metal plate through a fixing block. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the graphite welding head is fixedly connected with the upper copper seat, the metal plate is fixedly arranged on the welding surface of the graphite welding head, and during welding, the metal plate is contacted with a workpiece to be welded, so that the graphite welding head is prevented from being worn by the workpiece during welding, and the service life of the welding head is prolonged. According to the utility model, the copper wire is wound on the outer side of the graphite welding head, the copper wire is connected to the high-frequency device, the graphite welding head is heated in an electromagnetic induction mode, and when the next workpiece is welded, the graphite welding head is heated for heat preservation, so that the temperature of the welding head is ensured to be maintained at the working temperature when the workpiece is welded, the welding process is shortened, the occurrence of a cold joint problem is prevented, the processing efficiency is improved, and the welding quality is improved.
