Description
Technical field
The present invention relates to the manufacturing approach of stainless steel faucet, particularly relate to a kind of manufacturing approach of full punching stretch stainless steel faucet.
Background technology
Existing stainless steel faucet is most of to be hot investment casting; At first, the main body that hot investment casting goes out is heavy, and water channel is complicated; Have only through the welding transformation of the way; Can't reach production in enormous quantities, cost is high, and quality can't guarantee; Waste man-hour; Wanting just to go out one batch product 15 working days, can't reach with bend pipe processing and form a complete production network synchronously, is the maximum bottleneck that stainless steel faucet is produced at present; Secondly, the faucet surface of hot investment casting is coarse, and polishing just sand just can reach the basic effect of stainless steel pipe surface repeatedly for three times, to the repair welding repeatedly of sand pore, consume a large amount of manual works, and qualification rate is low, and specular light can not be thrown in the surface, can only the wire drawing processing; Three, the process-cycle of hot investment casting long, first-time qualification rate is low, surperficial sand pore is many, energy consumption is high, dust is big, belongs to the manufacture craft of high-carbon, high pollution.And tap made of copper at last just is also leaded, needs to electroplate, and environment is caused heavy metal pollution; Inner surface has patina, and is harmful, and the lead content of general copper tap is between 4-8%; Can not reach American AB 1953 leadless environment-friendly bill requirements, lack competitiveness, the incompatible following production.
Summary of the invention
To above-mentioned prior art; The technical problem that the present invention will solve provides a kind of manufacturing approach that adopts full punching stretch stainless steel faucet; Can solve the defective that above-mentioned hot investment casting stainless steel faucet exists; And can make lead content in the tap be lower than the requirement of American AB 1953 bills, more environmental protection.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of manufacturing approach of full punching stretch stainless steel faucet comprises following processing step:
A. the processing of stainless steel faucet main body:
(1) stainless steel tube is put into punching die and processed main body cover towards preparatory hole;
(2) main body cover is put in the in-draw of boss stretching die and goes out boss, stretch once more and shaping,, reach the size that needs the port part reducing;
(3) will stretch the main body cover of boss and port part reducing is with lathe, cutting machine and special fixture, milling machine processing boss plane;
(4) make stainless steel valve core print seat blank material and Vehicle Processing to the needs size;
(5), creep into water hole and apopore with the valve core case after the Vehicle Processing;
(6) inlet opening and the apopore that creeps into water hole and apopore valve core case carried out tapping, and orifice part is carried out chamfering;
(7) get the gapless stainless steel tube Vehicle Processing and go out the valve core case shell;
(8) with above-mentioned valve core case and the assembling of valve core case shell;
(9) integral body after valve core case and the combination of valve core case shell and main body cover are assembled formation stainless steel faucet main body;
(10) tap main body is carried out polishing just;
(11) just the tap main body of polishing carries out bottom thread processing and is polished to final required surface effect once more;
(12) to above-mentioned through the pressure testing of trying the water of the tap main body after twice polishing;
B. Discharging bent-tube processing: at the water side of Discharging bent-tube welding bubbler shell, fixing bubbler in the bubbler shell, other end welded stub connection, and Discharging bent-tube carried out polishing;
C. stainless steel faucet overall package:
(1) Discharging bent-tube is connected with tap main body top, water inlet pipe is connected with the tap main body valve core case, in the tap main body bottom screwed pipe is installed again;
(2) make spool, cooperate spool to make friction top, handle, spool is packed in the tap main body valve core case cavity, tighten friction top, the outer mounting knob of friction top;
As preferably, the mode of described main body cover stretching boss can also be that the water swelling form stretches.
As preferably, the assembling form of valve core case and valve core case shell is the threaded engagement form or ends the step fit form or for welding step fit form or be valve core case, the whole form processing of valve core case shell for car.
As preferably, the integral body after valve core case and the combination of valve core case shell and the assembling form of main body cover are the threaded engagement form or end the step fit form or whole and main body cover fits in reprocessing version for welding step fit form or for valve core case for car.
As preferably, described stainless steel tube is pipe or square tube and different in nature cross section pipe.
Compared with prior art, the present invention has the following advantages: 1. the process-cycle lacks, and first-time qualification rate is high, the no sand pore in surface; Belong to low-carbon (LC), low energy consumption, the oligosaprobic environmental protection industry (epi) of electroless plating; Specular light can be thrown in the surface, and lead content can reach the requirement of American AB 1953 bills below 0.025%; 2. can reduce the surperficial inaccessible density of smart casting through stainless steel faucet main body punching stretch solder technology effect, improve polishing efficiency, avoid repeating welding and repair welding and remedy smart casting surface blemish; 3. cost is low; At first; The punching stretch carbon emission is zero; And essence to cast the type carbon emission be that 1 ton of foundry goods needs 2 tons of standard coals; Secondly; It is 23 yuan of per kilograms that the stainless steel tube material is used in punching stretch production; It is 48 yuan of per kilograms that essence is cast type material; The 3rd; Punching stretch production polishing qualification rate 90%; Essence is cast type material and is produced polishing qualification rate 50%; The 4th, everyone 100 of punching stretch production comprehensive process production capacity (same style) average every days, everyone 10 of hot investment casting moulding material production comprehensive process production capacity (same style) average every days; 4. full punching stretch stainless steel faucet structural type cavity space is big, and the welding position is few, and wall thickness can reduce cost near 1.2 millimeters of the thickness of copper tap, improves surface quality and production efficiency, and the precision cast structure die cavity can not be accomplished below 2 millimeters.5. use full punching stretch stainless steel faucet controllable costs in the approaching level of copper tap, and need not to electroplate, but substantially exceed the copper tap service life, reach real alternative copper tap.6. adopt the stretched boss of punching stretch stainless steel faucet main body mould; Valve core case and valve core case shell composite entity and main body cover are combined to form the stainless steel faucet main body; Water channel can be accomplished with machine-tooled method; And the fillet position does not have the dead angle; Avoided the welding dead angle to polish, reduced polishing cost and man-hour, reached that processing forms a complete production network synchronously with bend pipe; Shorten the process-cycle, improve production capacity and reduce cost.
