Abstract
The invention relates to a manufacture method of a pipe fitting, and particularly relates to a manufacture method of a hot-melt type red copper composite tube. The invention discloses a manufacture method of a hot-melt type red copper composite tube. The manufacture method is characterized by comprising a tube manufacturing step and an extruding step, and specifically comprises the following steps: 1. manufacturing a copper strip into a copper tube by using tube manufacturing equipment and performing seamless welding; 2. rounding an inner tube wall and an outer tube wall of the copper tube; 3. removing oil stains from the rounded copper tube; 4. respectively compounding EVA (ethylene vinyl acetate copolymer) glue and PPR (polypropylene) outside the copper tube through the extruding equipment; 5. carrying out water-cooling on the compounded copper tube; and 6. cutting, packaging, and storing. According to the manufacture method, the production process is simple, automatic production can be realized through the tube manufacturing equipment and the extruding equipment, and the manufacture method has the characteristics that percent of pass is high, the production cost is low, large-scale production can be realized, and the social use requirement is realized.
Description
Technical field
The present invention relates to a kind of manufacture method of pipe fitting, refer in particular to a kind of heat molten type red copper composite pipe production method.
Background technology
The existing manufacture to red copper multiple tube is first to make finished product metal tube, manually metal tube is transported to extrusion equipment, then through complicated technique, carries out multiple glue.Every metal tube must not surpass 3 meters, and manual feed continuously, therefore need connect with special joint, also needs to take out joint after carrying out finished product, middlely as occurred, pauses, and tubing is scrapped and increased, and qualification rate is low, and tubing yields poorly, and is difficult for batch production.
Summary of the invention
The technical problem that one, will solve
The object of the invention is for the existing the problems referred to above of prior art, spy provides a kind of production technology simple, high and the heat molten type red copper composite pipe production method that can mass production of production efficiency.
Two, technical scheme
For solving the problems of the technologies described above, heat molten type red copper composite pipe production method of the present invention, wherein, is comprised of tubulation step and extrusion step, specific as follows:

2), the inner tubal wall of copper pipe and outer tube wall are carried out to full circle;
3), the copper pipe after full circle is dispelled to the processing of greasy dirt;
4), by the extrusion equipment compound EVA glue of difference and PPR outside copper pipe;
5), the copper pipe after compound is processed through water-cooled;
6), cutting-packing-warehouse-in.
As optimization, above-mentioned electric current while carrying out seamless welding is 28Hz, and hauling speed is 4.2m/min, and passing into volume is 2cm
3argon gas.
As optimization, temperature when compound EVA glue and PPR is 200 ℃, and recombination velocity is 5Hz.
Three, beneficial effect of the present invention
Production technology is simple, by tubulation apparatus and extrusion equipment, realizes automated production, has the advantages that qualification rate is high, production cost is low, realizes mass production, meets social user demand.
The specific embodiment
Below heat molten type red copper composite pipe production method of the present invention is described further:
Embodiment one: heat molten type red copper composite pipe production method of the present invention, wherein, by tubulation step and extrusion step, formed, specific as follows: 1), by tubulation apparatus, copper strips is made to copper pipe and carried out seamless welding, electric current when carrying out seamless welding is 28Hz, hauling speed is 4.2m/min, and passing into volume is 2cm
3argon gas, guarantee the stable of voltage simultaneously; 2), the inner tubal wall of copper pipe and outer tube wall are carried out to full circle; 3), the copper pipe after full circle is dispelled to the processing of greasy dirt by baking oven; 4), by extrusion equipment respectively compound EVA glue and PPR outside copper pipe, and temperature when compound EVA glue and PPR is 200 ℃, recombination velocity is 5Hz; 5), the copper pipe after compound is processed through water-cooled; 6), to the finished product after full circle, by length, need to cut, its hauling speed is 4.2m/min, and the finished product after cutting is packed and put in storage.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
