Abstract
The invention discloses a method for producing electric heating tubes heating evenly, belongs to the electric heating technology field. The invention has the technical proposal that: a method for producing electric heating tubes heating evenly, which is characterized in comprising steps: at first, a metal tube is provided according to the electric heating tube technology requirement and is processed the decontamination treatment, an eletroic heating wire with equal wire distance is produced by the machine winding wire method, two ends of the eletroic heat wire are connected to the educing stick and inserted into the magnesia tube; the second step, filling the powder: the eletroic heating wire and the magnesia tube are inserted into the metal tube, the magnesia powder is filled in inner and outside of the magnesia tube which is arranged in the metal tube; the last step, shrinking the tube, two ends of the metal tube are sealed by flexible plugs and is shrunk by the shrinking tube machine.
Description
Technical field
The present invention relates to the manufacture method of electrothermal tube, relate in particular to the manufacture method of uniform electric heating tube, belong to the electric-heating technology field.
Background technology
Existing electrothermal tube is made of heating wire, metal tube, magnesia powder etc., heating wire is arranged in the metal tube and does not contact with metal tube, magnesia powder is filled in the gap of heating wire and metal tube, and its manufacture method is as follows: at first specification requirement is got metal tube ready and is carried out decontamination and handle according to electrothermal tube; Heating wire adopts traditional tight wrapping wire method to make; During use heating wire is stretched to the length that is complementary with metal tube, and heating wire is placed in the metal tube; Magnesia powder is filled in the gap of heating wire and metal tube then, and uses the stamp stem tamping; Be filled with magnesian metal tube and carry out the draw and handle above-mentioned with machine for shrinking, purpose is to make the magnesia powder inserts more closely knit, thereby heating wire is fixed in the metal tube; At last with after the metal tube sealing two ends, heat-treat, moulding, sealing.Occur following shortcoming in the above-mentioned course of processing easily: 1, when heating wire is stretched to the length that is complementary with metal tube, the situation that flight lead does not wait just appears in heating wire easily; 2, when filling magnesia powder because will be with stamp stem with the magnesia powder tamping, in this course, easier spiral coil with heating wire presses together, cause the flight lead of the heating wire in the electrothermal tube to have nothing in common with each other, the heating wire flight lead does not wait, and energising back resistance is just inequality, the heating of electrothermal tube is just inhomogeneous, cause heating, the oven dry of product inhomogeneous, thereby influence the quality of product, also influence the useful life of electrothermal tube itself simultaneously.Along with developing rapidly of science and technology, people are more and more higher to the requirement of product quality, and existing electrothermal tube can not adapt to the requirement of industries such as weaving, medicine, chemical industry, food, plastics, are badly in need of wanting a kind of heating even on the market, safe and reliable, the electrothermal tube of long service life.
Summary of the invention
Purpose of the present invention is exactly the deficiency that overcomes existing manufacture method, and a kind of manufacture method of uniform electric heating tube is provided.
The object of the present invention is achieved like this: a kind of manufacture method of uniform electric heating tube is characterized in that may further comprise the steps:
(1) specification requirement is got metal tube ready and is carried out decontamination and handle according to electrothermal tube;
(2) wrapping wire: the medal spring resistance wire is adopted mechanical wrapping wire method, make the heating wire that flight lead equates;
(3) penetrate in the magnesia tube behind the two ends connection eduction rod with heating wire;
(4) heating wire, magnesia tube are pierced in the metal tube, and the inside and outside filling magnesia powder of the magnesia tube in metal tube, after the usefulness flexible plugs shutoff of metal tube two ends, adopt the machine for shrinking draw, make the magnesia powder of filling in the metal tube tightr;
(5) metal tube being heat-treated the back, to adopt insulator to seal between the two ends of metal tube and eduction rod fixing, and uniform electric heating tube is made in moulding, sealing.
Described mechanical wrapping wire method is promptly carried out coiling with spiral filament forming machine, specifically may further comprise the steps:
A, core bar is fixed on the chuck at spiral filament forming machine two ends and tension;
B, regulate screw gear on request;
C, heating wire one end is fixed on the chuck of spiral filament forming machine one end and passes through wiring frame;
D, start spiral filament forming machine, wiring frame carries out wrapping wire under the effect of leading screw;
E, wrapping wire finish to shut down, and unclamp spiral filament forming machine chuck taking-up heating wire and get final product.
Described magnesia tube is by magnesia powder and the pipe that is molded into after glue mixes.
Technology of the present invention is advanced simple, manufactures easily.The heating wire that the flight lead that electrothermal tube adopts machinery to turn to equates, the electrothermal tube heating is even, and the temperature difference is less than 10 degree.Heating wire is nested with the magnesia tube isolated insulation outward, guarantees that heating wire is in the center of metal tube, improves the security performance of electrothermal tube.Uniform electric heating tube adapts to the demand of industries such as weaving, medicine, chemical industry, food, plastics, satisfies heating evenly, and is safe and reliable, the long service life requirement.
