Abstract

The invention provides an automatic joint device and process for one-step forming of an inner rib pipe. The device comprises a hot air gun, transmission rollers, a discharge die, a spray water pipe, pinch rollers, an extruder, an electric three-jaw chuck and a rolling frame. The process comprises the following steps: S1, producing a PE melt by the extruder; S2, extruding the PE melt to a gap between the inner rib pipe and a bell and spigot by the discharge die, and melting the contact surface of the inner rib pipe and the chuck by the PE melt playing a role of a 'welding rod'; S3, flattening the melt at the gap between the inner rib pipe and the bell and spigot by using the pinch rollers; and S4, spraying water by the spray water pipe to cool the welding position for completing welding. Less manpower and time are required, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to an automatic jointing device and process for one-time forming of inner ribbed tubes. Background technique [0002] Since the rise of plastic pipes in our country in the 1980s, plastic drainage pipes have made great progress in our country. Plastic drainage and sewage pipes are widely used in urban drainage systems due to the advantages of light structure, corrosion resistance, non-toxic environmental protection, quick and convenient installation, etc. Various types of structural wall pipes have been developed in order to develop the advantages of plastics, overcome their disadvantages, and reduce costs while improving performance. [0003] In recent years, with the country's increasing emphasis on environmental protection, the governance of the water environment has been raised to a very high level. As early as 2010, Zhejiang Province took the lead in proposing the...
