A friction welding preheating mechanism and preheating method with static electricity removal function

Abstract

The invention provides a friction welding preheating mechanism with a static electricity removing function and a preheating method of the preheating mechanism. The mechanism comprises a friction welding support, wherein an upper mounting plate and a lower mounting plate which are parallel to each other horizontally and can move in a face-to-face manner or a back-to-back manner are arranged beside the friction welding support; an upper preheating mold is arranged on the upper side of the upper mounting plate; a lower preheating mold is arranged on the lower side of the lower mounting plate; and a movable frame which can shift horizontally to mounted a static electricity removing device is arranged between the upper mounting plate and the lower mounting plate. According to the preheating mechanism and the preheating method of the preheating mechanism, the structure is simple, the use is convenient, the static electricity removing device is mounted on the movable frame, positive and negative ions releasing high density interactively are used for impacting a component surface and neutralized with electrons and positrons of the component surface, a static electricity removing effect is realized in about 0.3 second, and an electronic component mounted in a product is prevented from being penetrating due to static electricity; and a to-be-friction-welded part is preheated, the welding quality of friction welding is improved, welding slag is bounded on two sides in strip shapes, welding dust is avoided, the preheating time is only ten seconds, and the energy-saving effect is remarkable.

Description

technical field [0001] The invention belongs to the field of friction welding, and in particular relates to a friction welding preheating mechanism and a preheating method with the function of eliminating static electricity. Background technique [0002] Friction welding is a kind of under pressure, through the friction interface of the workpiece to be welded and the temperature around it, the deformation resistance of the material is reduced, the plasticity is improved, and the interface oxide film is broken. A solid-state welding method that achieves welding by diffusion and recrystallization. At present, the existing friction welding equipment is bound by the traditional structure and welding method, and there are disadvantages such as poor welding quality, welding dust, energy consumption, and breakdown of electronic components installed in the product due to static electricity after friction welding.

Problems solved by technology

However, the disadvantage of this device is that after friction welding, the electronic components installed in the product will be broken down due to static electricity, and the welding quality needs to be improved.

Therefore, the existing friction welding equipment can no longer meet people's higher and higher requirements for workpiece welding quality. Therefore, a new type of friction welding equipment is urgently needed to improve the welding quality.
