Embodiment

[0013] In this embodiment: a method for manufacturing an electric heating tube assembly, the method performs the following steps:

[0014] 1) Winding a resistance wire with a preset length, the resistance wire is fixed on the base of the magnesium oxide tube, and then the two ends of the resistance wire are respectively fixed and sleeved on the upper wire positions of the two lead rods to obtain the resistance wire assembly;

[0015] 2) Set the resistance wire assembly in a metal tube, and use a powder feeder to add magnesium oxide powder to the metal tube, and then use a vibrating powder machine to vibrate the powder to obtain the blank of the electric heating tube assembly;

[0016] 3) Use the shrinking machine to shrink the electric heating tube assembly according to the preset size, so that the inner wall of the metal tube is in contact with the magnesium oxide base, and finally complete the production of the electric heating tube assembly;

[0017] 4) Seal the blank after...

Abstract

The invention relates to an electric heating pipe assembly production method. The electric heating pipe assembly production method comprises steps that 1) an electric resistance wire having a preset length is coiled; 2) the electric resistance wire assembly is disposed in a metal tube, a powder feeding machine is used to feed magnesium oxide powder in the metal tube, and a powder vibrating machine is used to vibrate the powder, and then the blank piece of the electric heating pipe assembly is acquired; 3) a pipe contracting machine is used for the pipe concreting of the electric heating pipe assembly according to a preset size, and the inner wall of the metal tube is contacted with a magnesium oxide base, and finally the production of the electric heating pipe assembly is completed. The magnesium oxide base is a cuboid column, the side wall of which is provided with a flat cable hole. The electric heating pipe assembly production method is advantageous in that the flat cable hole is used for fixing the position of the electric resistance wire, and the cuboid magnesium oxide pipe base is used to limit the position of the electric resistance wire, and therefore the powder vibration has no influences on the position of the electric resistance wire, and the cuboid magnesium oxide pipe base is used for limiting the contracted pipe.

Description

technical field [0001] The invention relates to a manufacturing method of an electric heating tube assembly. Background technique [0002] The voltage range of each country is different (100V-440V), the power range of the electric heating tube is different (100W-5000W), the use environment is different, the diameter of the electric heating tube is different, etc., which requires the design requirements and manufacturing process of the resistance wire of the product Higher and higher. Considering that the resistance wire in the metal tube is offset and dislocated during the powder vibration process, this phenomenon will cause the resistance wire to be short-circuited and blown, or even cause an explosion, and the resistance wire cannot be restored after it is made into a sealant. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a method for manufacturing an electric heating tube assembly in which the resistance wi...
