Vibration friction welder

Abstract

The invention discloses a vibration friction welder, comprising a device frame, a housing, a vibration head frame and a lower die lifting table, wherein the housing is arranged at the periphery of the device frame; and the vibration head frame and the lower die lifting table are arranged inside the device frame. An electromagnetic vibration head is arranged inside the vibration head frame. A lifting driving device is arranged at the bottom of the lower die lifting table, and mainly comprises a hydraulic cylinder, a linear guide pillar and a linear bearing. During the welding, the hydraulic cylinder pushes the lower die lifting table to rise along the linear guide pillar to the bottom of the vibration head frame to complete the welding under the action of the linear bearing, conversely, the hydraulic cylinder drives the lower die lifting table to reset. By the solution of the invention, the vibration friction welder has less component parts, simple connection way, low manufacturing cost, and high strength and sealing effect at a welding position. The tight welding can be achieved, so that the welding joint can meet the air-tight and watertight requirement. The vibration friction welder is suitable for the welding of a large-scale irregular workpiece, and is reliable in working. Acoustic absorbing materials are laid outside the housing, so that the noise pollution in a workshop is greatly reduced, and the vibration friction welder is very suitable for population.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a vibration friction welding machine with double-sided electromagnetic vibrating heads. Background technique [0002] Vibration friction welding is a welding method that uses electromagnetic transmission to generate relative motion between two thermoplastic parts, and then friction generates heat to form a joint. Vibration friction welding is fast and can be used to weld a wide variety of thermoplastics, especially in the automotive industry and the household appliance industry. At present, most of the plastic welding machines used in the market are ultrasonic and high-frequency welding machines, which cannot be welded due to limitations of materials (such as glass fiber, talc filler) or workpiece size (too large). It becomes very easy to weld with a vibration friction machine, but so far, the friction welding machines used in China have relied on foreign imports, and ...
