Description

Technical Field

[0001] The utility model relates to the field of heating equipment, in particular to a heating mechanism for pipe installation. Background Art

[0002] Pipes are carriers for the passage of liquids or gases. Common ones in daily life and production include water pipes, water and gas pipes, oil pipelines, etc. In the field of building decoration, PE pipe fittings are generally used in the process of laying water pipes. PE pipe fittings have the advantages of being easy to clean and not easy to corrode. During the installation process, PE pipe fittings need to be bent according to the installation requirements. During the bending process, PE pipe fittings need to be heated. The existing heating method is often manual heating, which has poor heating accuracy, uneven heating, and pipe fittings are not easy to bend. Therefore, it is particularly necessary to develop a heating mechanism for installation that heats evenly and facilitates the bending of pipe fittings. Summary of the Invention

[0006] Preferably, the pipe clamping mechanism includes a column, a three-jaw chuck is provided at the upper end of the column, and the three-jaw chuck extends coaxially with the heating pipe.

[0007] Preferably, the heating mechanism is a ceramic heater.

[0008] Preferably, a temperature sensor is provided inside the heating tube.

[0011] Preferably, a measuring ruler is slidably provided on the upper end surface of the base, the measuring ruler is parallel to the heating tube, and a limit rod is rotatably provided on the end of the measuring ruler, and the limit rod is perpendicular to the measuring ruler.

[0012] Compared with the existing technology, the beneficial effects are:

[0013] 1. The utility model inserts the pipe fitting to be bent into two pipe clamping mechanisms and passes it through the heating pipe, starts the heating mechanism and the reciprocating rotation mechanism, and uses the reciprocating rotation mechanism to drive the heating pipe to reciprocate, thereby heating the pipe fitting in the heating pipe, making it easier to bend the pipe fitting. The pipe fitting and the heating pipe extend coaxially, which has the advantage of uniform heating.

[0014] 2. The utility model uses a sliding measuring ruler to measure the position of the pipe fitting, thereby accurately determining the heating position, which has the advantage of accurate heating position of the pipe fitting. BRIEF DESCRIPTION OF THE DRAWINGS
