Description
Technical field
The present invention relates to a kind of is the water composite cooling pipe of welding industry welding gun, is a kind of inner-complex cooling pipe and manufacture method thereof specifically.
Background technology
During water cooled welding torch work, the temperature of its soldering tip reaches 2000～3000 ℃, in order to guarantee its operate as normal, needs water composite cooling pipe to come water flowing to cool off.During cooling, water enters from intake tunnel, through heat exchange, after cooling off, flow out from backwater channel, thus the cooling of realization Butt welding gun soldering tip.
The water composite cooling pipe of existing welding gun all is outer multiple tube as shown in Figure 1 usually, and as the outer multiple tube of four-way, the red copper that generally adopts the heat conduction better function is as base material.The manufacture method of the outer compound copper tube of four-way is at present: with the trade mark is that T2, state are that Y, diameter are the copper tube of φ 10mm * 2, presses the Len req sawing, mills out four road grooves by milling machine then.Selecting specification in addition for use is the copper tube of φ 12mm * 1, by the identical length sawing of four barrels.Adopt the mode of interference fits that four barrels are pressed into wherein, promptly finish the production of the outer multiple tube of four-way.There is following problem in traditional production technology: after 1, copper pipe was processed by milling machine, its surface smoothness was relatively poor, is unfavorable for the circulation of gas, water.2, because of milling machine can only mill a groove at every turn, each product needed is carried out four processing and just can be finished, thereby the precision of processing is low, accumulated error is bigger, is unfavorable for that the qualification rate of the assembling of finished product and product is lower.3, be subjected to the restriction of milling machine performance (length), the length of each converted products is shorter, thereby output is lower, and the production cycle is long, the production cost height.4, use milling machine to add trade union and produce a large amount of copper scales, material cost strengthens, and causes the serious waste of human and material resources, resource.5, product adopts the mode of interference fits to assemble.Be subjected to the influence of machining tolerance, can produce the gap when outer tube and the assembling of four barrels, the hot water or cold water can gang up (being commonly called as short circuit) during use, and cooling effect is poor.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the deficiencies in the prior art, provide a kind of heat exchange effect good interior compound cooling water pipe.
Another object of the present invention is to provide the manufacture method of compound cooling water pipe in this.
Technical scheme: in order to solve the problems of the technologies described above, the present invention adopted following technical scheme, a kind of inner-complex cooling pipe, and it comprises outer tube and interior pipe, interior pipe is arranged in outer tube, is provided with the not connected axial passage of even number between the inwall of the outer wall of interior pipe and outer tube.
Described axial passage is four, six, eight or 12.
The cross sectional dimensions of described axial passage is identical.
The manufacture method of above-mentioned inner-complex cooling pipe comprises the steps:
(1) draw in lining core garden: with the trade mark is that T2, state are that Y, specification are φ 38～40 * 3.0～4.3mm, and the red copper base pipe that length is 4～5 meters serves as a contrast and draws, and sky draws; This two procedures circulation is carried out until the base pipe being pulled to 28～21 * 2.6～4.0mm into φ;
(2) cover die grooving: the red copper pipe box shaped die that step (1) is obtained draws, and divides and finishes for six～eight times, promptly gets outer tube;
(3) draw interior pipe: with the trade mark is that T2, state are that Y, specification are φ 38 * 2.0mm, and the red copper base pipe that length is 4～5 meters serves as a contrast and draws, and sky draws; This two procedures circulation is carried out until the base pipe being pulled to 8～10mm into external diameter φ, and wall thickness is 1.0～1.65mm;
(4) cleaning: the inner and outer pipe compound to needs cleans, and removes attached to greasy dirt on the tube wall and copper scale, and be stand-by after drying;
(5) compound: as inner sleeve to be inserted in interior four barrels, once serve as a contrast pulling shaping.
Operation principle: being that hot and cold water pipe is alternately arranged in the passage of the present invention, promptly is the water inlet pipe of two logical cold water, two hot-water lines that go out hot water as the four-way inner-complex cooling pipe, the circulation cooling.And cooling evenly, good cooling results.
Beneficial effect: the present invention compares with traditional manufacture method, has the following advantages:
1, highly polished by the product surface of draw producing, adopted the fillet rounding off between each face of workpiece, guaranteed the smooth and easy of product ventilation, water flowing, satisfied instructions for use to greatest extent.
2, the profile of product is that one-off drawing is shaped, and dimensional accuracy height, error are little, and just with assembling, product percent of pass has improved 55%.
3, product with short production cycle, output is high, production cost is low.Compare personnel with traditional processing technology and reduce 20%, the electricity charge reduce 10%, save copper product 25%.
4, the compound of product is once to serve as a contrast pulling shaping in four barrels in interior multiple tube is inserted.Recombination process can produce an indenture at the outer surface of interior pipe, and product cooperates closely, has avoided the generation of short circuit phenomenon.
5, by drawing the compound production cost of producing that reduces manufacturer to greatest extent of four-way, improved cost performance of product: price only is about 38% of external like product, has really reached efficient, purpose of energy saving.
