Hot melting bushing welder

Abstract

The invention discloses a hot melting bushing welder and belongs to the welding field. The hot melting bushing welder comprises a rack, a fixing mechanism, a guiding mechanism and a hot melter, wherein the guiding mechanism and the fixing mechanism are mounted on the rack; the fixing mechanism comprises a pipefitting fixing device and a bushing fixing device for separately fixing pipefittings andbushings, the pipefitting fixing device is connected to the guiding mechanism, and the position of the pipefitting fixing device can be changed by means of the guiding mechanism; the bushing fixing device is also connected to the guiding mechanism, and the position of the bushing fixing device can be changed by means of the guiding mechanism; and the hot melter is used for heating the pipefittingsand the bushings. By matching the guiding mechanism with the fixing mechanism, the condition that at least two persons are needed to hold the pipefittings and the bushings at the left and right endsto apply forces during welding in the prior art is overcome, the manpower is reduced, and meanwhile, the whole welding process is steady and reliable, lasting in force, the welding difficulty is reduced directly, and the hot melting bushing welder can be widely applied to hot melting welding of plastic pipefittings such as PE pipes and PVC pipes in industries.

Description

technical field [0001] The invention relates to the field of welding, in particular to a hot-melt sleeve welding machine suitable for welding plastic pipes such as PE pipes and PVC pipes. Background technique [0002] In some projects for the main water supply and drainage system construction, a large number of water supply pipes are required. Due to the high cost of welded pipes, the time-consuming flange welding, the difficulty of on-site laying, the heavy weight that is not convenient for installation, and the need for more labor, etc., in order to save costs and facilitate the layout of existing terrain, some pipelines are laid with PE pipes. [0003] PE pipe connection usually adopts one of two methods: hot-melt plane welding and hot-melt sleeve welding. Due to the high and low terrain of the construction site, the pipeline needs to be bent with the terrain, and the water supply elevation is high, and the pressure that the pipeline needs to withstand is high, so the re...

AI Technical Summary

Problems solved by technology

At present, when welding the hot-melt sleeve of PE pipe, one person must hold the fuser in the middle, and at least two people on the left and right should hold the PE pipe or joint for hot-melt welding. Propelling the pipe or joint with the device, a little carelessness will cause the PE pipe or joint interface to be skewed, making it difficult to connect the interface, or even cause waste pipes. rest

Welding is time-consuming and labor-intensive, produces a lot of waste pipes, unstable quality, low work efficiency, and high cost
