A Mechanical Vibration Friction Heat Generation Fusion Splicer

Abstract

A welding machine adopting a manner of generating heat by mechanical oscillation friction is disclosed. The welding machine comprises a driving motor, a power transmission mechanism, a welding mechanism by heat generated by friction, and an axial force applying mechanism. The power transmission mechanism is connected to the output end of the driving motor, and is connected to the welding mechanism by heat generated by friction through a transmission connecting rod. The axial force applying mechanism is installed on a side surface of the welding mechanism by heat generated by friction. The axis of the axial force applying mechanism and the axis for installing a plastic pipe to be melt on the welding mechanism by heat generated by friction are at the same straight line, thus locking and loosening the plastic pipe. The welding machine adopts friction to generate heat so as to perform sweat welding on end surfaces of pipes having the same diameter, reduces the using cost of sweat welding, and is free of crevasse treatment and simple in process. The axial force applying mechanism is added, so that locking and loosening of the pipes can be achieved, thus making pipe welding stress even, improving pipe welding quality and increasing the welding efficiency.

Description

Technical field [0001] The invention belongs to the technical field of welding and processing of plastic pipe fittings, and in particular relates to a mechanical vibration friction heat-generating welding machine. Background technique [0002] Plastic pipes are generally made of plastic resin as raw materials, added with stabilizers, lubricants, etc., and processed by extrusion in a pipe making machine by injection molding. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction, etc., it has been widely used in construction engineering. With the wide application of plastic pipes, as an indispensable connecting part for plastic pipes, it has also been developed rapidly. Plastic pipe joints are particularly prominent, with a wide variety of products. However, the existing plastic pipe joints are different from the connected parts. Therefore, there is a large amount of materials and high processing costs in th...

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 car is large in size and heavy in structure, and is only suitable for the connection and laying of plastic pipes, not for the welding of equal-diameter plastic pipe fittings; at the same time, the welding car does not have any force-exerting device during welding, resulting in The welding force of the pipe fittings is not uniform, and there is a phenomenon of poor welding, which affects the welding quality of the product
