Description
Technical Field
The utility model belongs to the technical field of the hot melt ware technique and specifically relates to an apply to hot melt ware of heavy-calibre tubular product.
Background
The hot melt device is a special welding tool for heating, melting and then connecting thermoplastic pipes and molds. The hot melt device plays a crucial role in the process of connecting the pipe with the fittings and the like. The hot melting device is mainly used for welding pipe fittings such as PVC pipes and PE pipes, the hot melting device in the market is still good for the pipe fitting with the caliber smaller than 40mm, but the defect is also very obvious for the welding of the pipe fitting with the caliber larger than 90 mm.
Tubular product need design pipeline layout in-service use, need the pipe fitting to use as the adapter cooperation this time, and the theory of operation of common hot melt ware is: an operator holds the pipe by one hand and holds the pipe by the other hand, and simultaneously sleeves the pipe and the pipe on the fusion ports at the left end and the right end of the hot fusion device respectively, the hot fusion device heats the outer surface of the pipe and the inner surface of the pipe respectively, and then sleeves the pipe subjected to heating treatment with the pipe to realize fusion.
In the actual operation process, the technical personnel in the field find that the welding mode is suitable for the small-caliber pipe, but the welding mode for the large-caliber pipe has the following defects: firstly, the method comprises the following steps: because the heating time of the large-diameter pipe is longer, and the wall thicknesses of the pipe and the pipe fitting are different, the heating degree of the pipe in the same time reaches the requirement, the heating degree of the pipe fitting is not enough, the welding effect is not good, and the pipe fitting is easy to fall off; the heating time is prolonged, so that the pipe is easy to melt and deform, and the material is scrapped; II, secondly: the large-diameter pipe is not easy to hold and release, and even in any case, an operator needs to hold the pipe by one hand and hold the pipe by the other hand and simultaneously sleeve the pipe and the pipe on the welding ports at the left end and the right end of the hot melter respectively, so that the construction is difficult, and the heated pipe and pipe sleeve joint needs large force, so that the welding effect is greatly influenced; thirdly, the method comprises the following steps: when the large-caliber pipe fitting is sleeved, the upper material of the inner wall of the pipe fitting is extruded to cause protrusion, the protrusion can influence the flow velocity of fluid in the pipe, the fluid can generate acting force on the joint, and the pipeline at the welded joint drops as time passes.
