Description
Technical field
The present invention relates to the process of tubulose plumbing, specifically refer to the stainless steel condensate correcting-distribuing device supervisor's of a kind of tool plane boss processing method.
Background technology
In chemical industry, pharmacy, petrochemical industry, brewage, in the enterprise such as food, beverage, for the fluid foods such as water, oil, steam are carried out centralizedly supply and distribution, often will set up the control operation platform of a centralized distribution, namely the fluid collection divides device.In recent years, this fluid collection subsystem is applied in the living facilities of home dwelling.The for example the northern area of China residential quarter central heating, liquefied gas station air feed, solar water heater water stop etc. of dwelling house in flakes.In some cities of Yangtze River Delta Region, at present just in the hot water collection subsystem of the self-produced flow of hot water of popular Domestic gas water heater to oneself each room: namely again flow to the underground heat comb that be arranged on each room floor under through being arranged on after controlling the condensate correcting-distribuing device of handling in cabinet from wall-mounted gas water heater hot water out, for each room heating.So-called condensate correcting-distribuing device is exactly one section supervisor who is provided with water inlet control valve and branches out water control valve in fact.The two ends of this class pipe and sidewall all are provided with internal thread interface, so that by-pass valve control is installed.Condensate correcting-distribuing device supervisor mostly form with brass casting in early days, so inwall is all more coarse, and the viscosity resistance when fluid is carried is larger, affects flowing velocity and the flow of fluid, from energy-saving and emission-reduction and the angle that economizes on resources, is uneconomic.And this fluid collection distributor is difficult to processing and can not does oversizely.So the applicant has invented a kind of patent No. of stainless steel stretched moulding in 2006 be 200620042782.6 " the fluid collection divides device ", its inwall is need not machining namely very smooth, and when fluid is carried, resistance is less.And without machining, so its length and branch's number are unrestricted, be convenient to the product formation seriation because of inwall.But this product is also aobvious attractive in appearance not in shape, and the screw thread mouth at valve installation place is comparatively weak.The applicant had carried out larger improvement to its profile on this basis in 2010, trial-produceed " interface has the stainless steel condensate correcting-distribuing device supervisor of plane boss along separate routes " successfully, applied for china national practical new-type patent and obtained the authorization on March 15th, 2010, the patent No. is 201020158055.2.And process has been carried out test of many times and improvement, and the present invention is exactly the manufacturing process of this product and the detailed description of processing method.
Summary of the invention
The technical problem to be solved in the present invention is: for providing a kind of good looking appearance generous to domestic hot water's supply system, control valve and along separate routes the outlet valve installation place have the stainless steel condensate correcting-distribuing device supervisor of plane boss and the preferred processing technology of working out.
The technical scheme of technical solution problem of the present invention is: the condensate correcting-distribuing device supervisor's of a kind of tool plane boss processing method, experience comprise get the raw materials ready, pipe crimping, welding, shaping, boss forming, punching, turn over inner edge, reducing, turn over the outside, turning, sanding and polishing operation:
A) get the raw materials ready: get the stainless steel materials of 1.5～3.0mm thickness, cut into rectangle by diameter and the length requirement of product, the minor face of rectangle is the pipe girth of condensate correcting-distribuing device supervisor's wall thickness centerline, and long limit is namely supervisor's length;
B) pipe crimping: the stainless steel materials of planar rectangular is processed into round tube shape on special-purpose rolling machine;
C) welding: will be rolled into the blank seam welding of round tube shape with nickel electrode, and reach the tight smooth requirement of weld seam;
D) stretching shaping: stretch on special-purpose stretching-machine fill in internal mold in the pipe of welding fabrication after, make its inwall reach smooth requirement;
E) boss forming: with the pipe of above-mentioned stretched shaping, be placed in the special-purpose external mold with several plane boss and carry out moulding, make it form square boss at the shunt interface;
F) punching: enter internal mold to above-mentioned inner plug of tube through expansion, carry out punching in boss center, plane with forcing press;
G) turn over inner edge: the aperture of the pipe boss after above-mentioned punching, carry out punching press for the second time with forcing press, make orifice edge to 90 ° of in-flanges;
H) reducing: pipe two ends are withstood on pattern push, make the mouth of pipe inside reducing in two ends form the circular cone shape that transition is connected with round platform;
I) turn over the outside: 45 ° of the outward-dipping flange in the edge of the round table-like mouth of pipe that will inside contract;
J) turning: be included in boss hole in-flanges car interface thread, the two ends mouth of pipe turn up sidecar light chamfering, two ends mouth of pipe car internal thread interface;
K) sanding and polishing: will carry out the surface finish polishing through the condensate correcting-distribuing device supervisor of above-mentioned operation processing, until reach the fineness requirement.
Preferably: in described punching operation, the internal mold of filling in is at least three blocks of overlapping steel plates, purpose is convenient in order to take out mould after punching, is provided with the boss that matches with pipe boss inner wall shape on the steel plate of both sides, and is provided with the punch die hole at the center position of boss.
With processing method processing condensate correcting-distribuing device supervisor of the present invention, make stainless steel materials obtain fully rationally utilizing, and interface thread need not weld in addition, whole manufacturing process is accomplished without any letup, no matter be that semi-mechanization or fully-automatic equipment can be made, and tube length and branch's number are unrestricted, are convenient to form product seriation.Tool plane boss stainless steel condensate correcting-distribuing device supervisor after moulding, its inner wall smooth, good looking appearance are generous, and control valve is installed firm, solid.
