Description

Technical Field

[0001] The utility model relates to the technical field of laser welding wire feeding, in particular to a PE elbow hot-melt welding tool. Background Art

[0002] The PE elbow hot-melt welding tool is a device used to connect polyethylene (PE) pipe elbows in a pipeline system. In a PE pipeline system, it is usually necessary to connect the pipe elbow to the pipeline in order to achieve the flexibility of the turning and layout of the pipeline line. Hot-melt welding is one of the common methods for connecting PE pipes and pipe fittings. However, during the use of the existing device, the pipe to be connected is usually placed inside the heating mechanism, and then the pipe is clamped by the clamps on both sides of the heating mechanism. The heating mechanism is a hollow cylindrical structure with a heating plate inside. However, when the existing device performs hot-melt welding on the pipeline, there is a situation where the ports of the two pipes that are hot-melt welded melt and drop slag during the welding process. This situation will cause gaps to appear at the connection after the hot-melt processing of the pipeline, and then the pipeline needs to be reworked and hot-melt welded again.

[0003] The implementation of the utility model aims to provide a PE elbow hot-melt welding tool to solve the problems raised in the above-mentioned background technology. Utility Model Content

When the pipes at both ends or one side are bent pipes, the staff can remove the connecting bolts from one side of the spring, remove the clamp connecting rod, and then fix the connecting rod to the outside of the spring through the connecting bolts. When the device is used for hot melting in a relatively narrow working environment, the staff can clamp the bent pipes in different directions by changing the clamping tools at both ends of the device, thereby eliminating the need for the staff to change the position of the pipe or the overall direction of the handling device in a narrow environment for welding operations.
