Embodiment Construction

[0020] In order to make it easy to understand the technical means, creative features, achieved goals and effects of the present invention, the present invention is further described below.

[0021] An electric heating pipe processing technology, comprising the following steps:

[0022] Step 1: Process the heating wire, install the heating wire on the lead rod and perform spot welding; the details include:

[0023] 1. Use a wire winding machine to wind the heating wire into a spring shape to meet the specified wire diameter and resistance requirements;

[0024] 2. Clean the oil on the surface of the heating wire by an ultrasonic cleaning machine, and put it into an oven for drying;

[0025] 3. Drive the lower lead rod into the inner hole of the rubber pellet through the automatic rubber stopper machine to reach the specified exposed length;

[0026] 4. Use the automatic wire threading machine to thread the heating wire on the threading position of the upper and lower lead bar...

Abstract

The invention relates to a processing technology of an electric heating tube, which comprises the following steps: 1. heating wire processing, installing the heating wire on the lead rod and performing spot welding; 2. filling powder, changing the structure of the rubber plug used in the powder filling process, adding glue Plug the creepage distance between the lead rod and the nozzle, and then use a powder filling machine to penetrate the heating wire into the empty tube and fill the gap with dense magnesium oxide powder; three: riveting, riveting the rubber plug of the nozzle and the electric heating tube into a hexagonal shape, tightly connecting the rubber plug and the electric heating tube; four: stretching, using a riveting mold to rive the nozzle rubber plug and the electric heating tube into a hexagonal shape, so that the rubber plug and the electric heating tube are tightly connected; five: cutting the rod, and The lead-out rods are cut into consistent exposed lengths; six: tube bending, use a tube bender to bend the electric heating tube into a specified shape and meet the size requirements of the drawing. The invention overcomes the disadvantages of wasting materials and dust polluting the environment caused by the traditional process, and has the advantages of simplifying process steps and improving processing efficiency.

Description

technical field [0001] The invention relates to the technical field of electric heating pipe processing, in particular to an electric heating pipe processing technology. Background technique [0002] At present, the traditional electric heating tube processing process is: heating wire processing, powder filling, tube shrinking, car tube, powder digging, rod cutting, and tube bending. The products produced by the existing tube shrinking process will have the problem of inconsistent tube length. The main reason is that the powder filling density of each product will be different, the elongation rate of each tube will be different, etc., and the car tube process will be added later. To make the pipe into a uniform length, it is necessary to add a powder excavation process to remove the excess magnesia powder at the nozzle. This process requires the part of the length of the car to go, resulting in waste of raw materials, and dust pollution in the car tube and powder excavation...
