An Axial Force-Forcing Mechanism for Welding Plastic Pipe Fittings with Equal Diameters

Abstract

The invention discloses an axial force applying mechanism for fusion welding of an equal-diameter plastic pipe fitting. The axial force applying mechanism comprises a base, a guide block, an eccentric level and a hinged base, wherein the guide block is arranged on the base, a pin base is arranged on the guide block, one end of the eccentric level is connected with the pin base by a hinge pin A, the other end of the eccentric level is connected with the hinged base by a hinge pin B, and a force applying clamp is also fixedly arranged on the guide block; and the force applying clamp comprises a clamp base and a pressing block, the clamp base is of an L-shaped structure, and the pressing block is fixed above the L-shaped structure by a bolt. According to the axial force applying mechanism for the fusion welding of the equal-diameter plastic pipe fitting, the eccentric level and the force applying clamp are combined, the eccentric level is rotated to enable a sliding block to move left and right, and the force applying clamp has a function of clamping and loosing the pipe fitting; pipe fitting welding stress is uniform, and the pipe fitting is prevented from shifting, so that the butted-jointing deformation or poor butted-jointing effect is avoided, the welding quality and the welding efficiency of the pipe fitting are greatly improved and the passing percent of products is increased.

Description

technical field [0001] The invention belongs to the technical field of plastic pipe processing, and in particular relates to an axial force applying mechanism for welding plastic pipe fittings with equal diameters. 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 p...

AI Technical Summary

Problems solved by technology

Such equal-diameter plastic pipe products are usually butt-jointed by using a hot-melt machine. However, when the existing hot-melt machine performs hot-melt butt joint on the pipe fittings, because the pipe axial direction is not equipped with any clamping measures, the The welding process leads to poor seam welding, which affects the quality of the weld, and the product or rhythm is reduced
