Description
Technical field
The present invention relates to tap connector production Technology, especially a kind of process for making being applicable to the S shape joint hanging wall tap.
Background technology
At present, hot and cold water wall suspended type water taps is widely used in the bathing such as bathtub, shower place, S shape joint is as the main connection fittings of tap, S shape joint plays the effect of connecting pipe and tap, S shape joint, when normal mounting, subjects a whole set of leading weight, through expanding with heat and contract with cold for a long time, being corroded and material is oxidized, the service life of S shape joint can be shortened, thus have influence on the life-span of overall tap.
Prior art adopts founding to manufacture S shape joint usually, this casting method step complexity is loaded down with trivial details, energy consumption is large, be confined to the defect of technology, easily there is projection in the S shape joint finished product produced, the defect such as to break, and product strength and corrosion resistance are also poor, reduce performance and the yield rate of product, cause the quality of S shape joint can not be guaranteed.In addition, the processing technology difficulty of existing S shape joint casting method, causes production cost relatively high.
Summary of the invention
In order to solve the problems of the technologies described above, the process for making of a kind of S shape joint provided by the invention, this process is simple, easy to operate, effectively enhances productivity and yield rate, and the quality requirement of product is guaranteed simultaneously.
To achieve these goals, the technical solution adopted in the present invention is:
A process for making for S shape joint, this process comprises the following steps:
Step one, the solid bar of preparation metal material;
Step 2, heats solid bar;
Step 3, equipment of being sent into by the solid bar through heating carries out cold-heading or thermal forging technology processing, forms T-shaped hollow pipe;
Step 4, carries out punching press process by T-shaped hollow pipe, forms S shape joint blank.
Above-mentioned cold heading technique completes on cold headers, concrete cold-heading process is, solid bar is by feed mechanism automatic feed cold headers, and shut-off mechanism is cut into blank, is then delivered to successively by clamp transport mechanism and builds up swaging and punching station and carry out cold upset forming.Complete blank by cold-heading function order, the poly-long-pending ﹑ of upsetting head ﹑ becomes the operation such as the shape ﹑ ﹑ of falling angle undergauge and trimming, production efficiency is high, can reach 60-70/minutes.
In step 3, thermal forging technology process completes on forging equipment, solid bar is sent into forging equipment, forge through steps such as shearing, extruding, punching, trimmings, make solid bar produce plastic deformation, thus obtain the effigurate blank of tool, this technique not only can obtain the shape of certain metal parts, and metal inside tissue can be improved, improve mechanical property and the physical property of metal.
In above-mentioned processing step, also comprise step 5, in the two ends Vehicle Processing or rolled threaded of S shape joint blank, make S shape joint finished product.
In above-mentioned processing step, the temperature heated in step 2 is 500 DEG C-1000 DEG C, by being heated to specific temperature, can ensure that solid bar has enough degree of drawings, being conducive to easier upsetting system in cold-heading process extruded.The object of heat temperature raising is solid bar is softened, when deforming temperature is increased to more than recrystallization temperature, because recrystallization speed is higher than speed metal hardening in deformation process, hardening effect can be eliminated and obtain recrystallized structure, less external force can be utilized to make metal produce larger plastic deformation and unlikelyly to break.
In above-mentioned processing step, the solid bar of employing is stainless steel, copper or aluminum alloy material, and the S shape joint design of manufacture is firmly stable, and resistance to corrosion is strong, and heavily fortified point is durable for a long time.
Beneficial effect of the present invention: the process of above-mentioned manufacturing S shape joint, cold-heading or thermal forging technology technology is adopted to carry out machine-shaping to solid bar, solid bar plasticity in technical process is very high, unusual cross sectional shape can be obtained economically, obtain gratifying strength-weight ratio, integrally formed S shape joint avoids cast article structure not compact, the shortcoming of tissue looseness, product is made to have higher intensity and mechanical property, improve service life and yield rate, and stock utilization can reach 80 ~ 90%, processing step is simplified, production cost is reduced, product quality improves, improve economic benefit.

Detailed description of the invention
See shown in Fig. 1 to Fig. 4, the process for making of a kind of S shape joint provided by the invention, this process comprises the following steps:
Step one, the solid bar 1 of preparation metal material;
Step 2, heats solid bar 1;
Step 3, equipment of being sent into by the solid bar 1 through heating carries out cold-heading or thermal forging technology processing, forms T-shaped hollow pipe 2;
Step 4, carries out punching press process by T-shaped hollow pipe 2, forms S shape joint blank 3;
Step 5, in the two ends Vehicle Processing or rolled threaded of S shape joint blank 3, makes S shape joint finished product 4, and obtained S shape joint point diameter is larger than rear end diameter, and front end is water outlet mouthpiece, and rear end is water inlet interface.
In above-mentioned steps two, the temperature of heating is 500 DEG C-1000 DEG C, by being heated to specific temperature, can ensureing that solid bar 1 has enough degree of drawings, being conducive to easier upsetting system in cold-heading process extruded.
In step 3, cold heading technique process completes on cold headers, and solid bar 1 is by feed mechanism automatic feed cold headers, and shut-off mechanism is cut into blank, then delivered to successively by clamp transport mechanism and build up swaging and punching station and carry out cold upset forming.Complete blank by cold-heading function order, the poly-long-pending ﹑ of upsetting head ﹑ becomes the operation such as the shape ﹑ ﹑ of falling angle undergauge and trimming, can reach 60-70/minutes, production efficiency is high.Cold heading technique technology is adopted to carry out upsetting processing and forming to solid bar 1, solid bar 1 plasticity in technical process is very high, cold heading performance is very good, unusual cross sectional shape can be obtained economically, obtain gratifying strength-weight ratio, and stock utilization can reach 80 ~ 90%, save consumptive material.
