A plastic pipe fitting welding machine

Abstract

The invention discloses a plastic pipe fitting welding machine. The plastic pipe fitting welding machine comprises a power mechanism, an eccentric rotation mechanism and a mechanical vibration friction heat generation mechanism which are arranged on a frame, the power mechanism is arranged below the frame and is connected with the eccentric rotation mechanism through a synchronous belt, the eccentric rotation mechanism is connected with the mechanical vibration friction heat generation mechanism, two sides of the mechanical vibration friction heat generation mechanism are respectively provided with a positioning clamp and an axial boosting mechanism, and the center of the positioning clamp and the center of the mechanical vibration friction heat generation mechanism and the axial boosting mechanism are positioned in a same straight line. Thermal melting welding of transverse planes of equal diameter pipe fittings is carried out through adopting friction heat generation, so the use cost of thermal melting welding is reduced; and the axial boosting mechanism and the positioning clamp are combined, so the locking and loosening effects of pipe fittings can be realized, thereby the pipe fitting welding stress is uniform, and the welding quality and the welding efficiency of the pipe fittings are improved.

Description

technical field [0001] The invention belongs to the technical field of plastic pipe welding, and relates to welding equipment, in particular to a welding machine for plastic pipe fittings. Background technique [0002] Plastic pipes are generally made of plastic resin as raw material, adding stabilizers, lubricants, etc., and extruded in a pipe making machine by injection molding. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, and convenient construction, it has been widely used in construction projects. With the wide application of plastic pipes, the connecting parts that are indispensable for plastic pipes have also been developed rapidly. Among them, plastic pipe joints are particularly prominent, and there are many types of products. However, the existing plastic pipe joints are different from the parts to be connected. , so there is a large amount of materials used in the manufacturing process and high processing...

Problems solved by technology

However, because the welding machine welds two pipes into one long pipe through a hot-melt welding machine during welding, the welding end of the plastic pipe needs to be cracked and then electrically heated for butt welding, the welding process is complicated, and the use of heat Fusion welding increases the welding cost; the welding vehicle is large in size and heavy in structure, and is only suitable for the connection and laying of plastic pipes, not for welding of equal-diameter plastic pipe fittings; at the same time, the existing plastic pipe welding equipment does not have any booster device, Therefore, it leads to poor seams during the welding process and affects the quality of the weld
