CSW, the design that 500 horizontal double-loop seams automatic welder and application

Equipment solders the configuration of power source form and more well-known, one of crucial factors of welding line quality are to solder the configuration of power source. Inside and outside of eye front wall has 4 kinds to power source is configured or solder method, for preferred choose, we undertook contrasting analytic. (1)CO2 gas protects power source (extremely fused) use CO2 gas to do protection. Advantage: CO2 gas price efficiency of low, production is tall, solder current density is tank depth of frit of matrix of big, weldment, fused efficiency rate of apply of tall, frit is rapid, manufacturing efficiency is taller than manual solder 2 ～ 4 times, and it is good to fight rust, crack resistance; Defect: When big electric current solders, solder exterior take shape is wronger, splatter more, those who be stuck on workpiece need to get rid of artificially after solder splatter content. (2)MIG gas protects solder (extremely fused) , use argon gas to do protection. Advantage: Solder bath deepness is big, solder figuration of electric arc stability, welding line efficiency of good, production is tall; Defect: Because protect gas to come true with argon gas,solder process, on the high side of argon gas price and MIG solders power source relatively CO2/MAG solders power source is valuable on the price 3 ～ 4 times. (3)MAG gas protects solder power source (extremely fused) . Use argon gas and protection of CO2 gas mixture, among them argon gas is 20 ％ for 80 ％ , CO2. Advantage: Solder frit tank depth spends efficiency of apply of big, frit tall, solder splatter lesser, can gain stability solder process and beautiful welding line. (4)TIG gas protects power source (blame is extremely fused) , use argon gas to do protection. My company uses normally solder power source is this a kind (by hand) of solder of arc of tungsten pole argon. Advantage: Heat through electric current only as a result of electrode workpiece, make workpiece and welding wire form bath reason to did not splatter products is crude, welding line figuration is beautiful; Defect: Apply of shallow, frit leads deepness of electric arc bath efficiency of low, production is not tall. Because of soldering the process uses argon gas to do protection entirely, price on the high side. The contrast that through soldering power source configures reachs the expert's proposal, use CO2/MAG to solder certainly power source configuration will make double-loop seam solder automatically machine tool. 2.

Of equipment form with working principle (of 1) equipment form this equipment to carry orgnaization of clamp of slip orgnaization, rotational orgnaization, workpiece on the head by end of slideway bed body, rotational revolving stage, pneumatic, among hold welding torch of makings orgnaization, private plane in the palm pneumatic adjustment, welding torch is three-dimensional fine tuning. If the graph is shown 1 times,horizontal double-loop seams automatic welder structure. (2) job principle uses roll to carry clamp work, another end carries the means of close workpiece on the head, welding torch of double head CO2 solders relative to immobile principle and CO2/MAG power source matchs what implementation workpiece annulus seams to solder. (The suitable scope ① of 3) equipment applies to the seam welding of planar circle annulus such as carbolic steel and body of stainless steel a powerful person, flange to receive. ② annulus seams the smallest diameter to be 25mm, the biggest diameter is 120mm. Body of ③ a powerful person and work of flange group solder are the greatest length is 360mm, flange is the biggest the diameter is 260mm. ④ work is the greatest weight is 45kg, the machine tool is the biggest circumgyrate diameter 450mm. (The characteristic ① of 4) equipment advocate rotational part uses transmission of machine of decelerate of standard worm wheel, communicate frequency conversion electromotor, rotate speed stepless adjusts, rotational fixed position dish jacket has workpiece fixture. Charging tray is held in the palm to use pneumatic to move up and down among ② , hold charging tray and orgnaization of slip of pneumatic end top in the palm at the same time along the machine tool but fore-and-aft adjustment, differ in order to get used to different length the workpiece of norms. When adjusting convenient, quick, and location is exact. ③ uses adjustment of platform type welding torch, adjust the axial position of welding torch; Use bearing of accurate and linear bearing, the hand is moved adjust welding torch distance, three-dimensional adjustment and welding torch fixture use welding torch aluminium alloy is crossed tone wearing makes welding torch clip is held firm and reliable, the position of welding torch adjusts convenient also, agile. ④ equipment is had build receive quantity adjustment and automatic restoration to wait for a function to initiative condition. ⑤ equipment has aleatoric dot to rise, function receiving arc. ⑥ control uses an entrance partly high-powered PLC regards core as control unit, undertake to the system data collects control centralized, operation interface operates an orgnaization for pushbutton type, fault rate is low master easily. Figuration double-loop seam welding receives ⑦ . ⑧ operation is convenient, adjust easily, group solder is different standards body orchid combine when, equipment is adjusted need 5min left and right sides to be able to be finished only commonly. 3.

Of equipment solder automatically the program presses → of the pushbutton that start holds charging tray in the palm to rise reach the designated position → waits for body of solder a powerful person, flange put in fixed position respectively dish reach hold top of end of pneumatic of the → on charging tray in the palm to reach the designated position it is good that → of very close workpiece adjusts position of good welding torch and angle → solder speed, solder electric current, pneumatic end is very loose → debus workpiece, enter next loop. 2, body of a powerful person and flange double-loop seam solder automatically example (body of 1) a powerful person and flange material analyse for ASME A105, its fusion and product chemistry composition sees next tables: (2) forged steel bear body of a powerful person of the brake that insert solder, a powerful person and flange solder combine a norms, dimension to see a picture 2. (Art solder material chooses 3) welder brand: GB/MG, 49, 1, model: GB/ER, 49, 1 or ASME ER70S, G. Welding wire chooses norms: φ 1.

Voltage of 2mm, electric arc 20 ～ 30V, solder electric current 200, discharge of 300A, gas 20 ～ 25L/min. (4) double-loop is seamed solder automatically the result is one-time solder end, the welding line exterior after figuration is beautiful, fluent, uniform, immanent solder quality classics RT examines without any weld defects. 3, new old solder the contrast of equipment and method is Z41H with model only, 40FB, the body of a powerful person of 50 and flange combination for exemple undertake soldering contrasting: Before body of a powerful person and flange combine a solder to put through often is to be on machine tool of special fixed position, first standing valve body and flange position, with welding rod arc welding or handiwork solder of arc of tungsten pole argon undertakes at 3 o'clock tack welding, place next hold soldering change implement on with handiwork solder of arc of tungsten pole argon undertakes annulus seam welding receive, solder layer is 2 ～ 4. After soldering at the same time, move conversion buy to solder again another, a skilled solderer needs ability of 9 ～ 10min to combine solder end. Such process that apply solder makes solderer labor strength great, manufacturing efficiency is low, suffer factitious operation skill to affect, solder quality is couldn't get assure, take shape of exterior welding line is wrong, take a lot of work, take time and increased to solder cost. Use horizontal double-loop to seam automatic welder now, want a body of a powerful person and zone only Kong Falan is soldering machine tool after fixed, clamp, can undertake annulus seam welding receives synchronism of double gun double silk, and locate accurate, parallelism alignment error of both sides flange is dinky. Weld time needs only 1.

5min, one-time finish solder entirely process. 4, economic benefits is body of 50min a powerful person and belt with norms Kong Falan is exemple: Body of an a powerful person and flange secure former group solder charge of spot welding man-hour 0.

34 yuan, the charge when group solderer 1.

53 yuan, cost of the cost that enrage disappear 0.

82 yuan, seam automatic welder to solder with double-loop now, incorporate two working procedure finish for a working procedure. The charge when welder is 0.

65 yuan, gas spends charge 0.

30 yuan, plan every are covered but managing and artificial charge 1.

22 yuan, managing gas spends charge 0.

50 yuan, press year of group solder all sorts of norms valve are calculated 80 thousand sets, other item not plan, produce cost cost only but managing 100 thousand yuan or so, and this welder purchased charge to be used only 9.

40 thousand yuan. Former manual tungsten extremely body of a powerful person of solder of group of argon arc solder and flange repair rate is controlled in 3 ％ all the time, use rate of repair of solder of machine tool group to fall now 1 ％ is the following, it is annual and OK to be this managing repair expenses amounts to 10 thousand yuan of above. This shows, its economic benefits is very considerable. 5, epilogue cleanness, efficient, low cost and automation are to solder the objective that the technology pursues for a long time, with CSW, the handiwork that 500 horizontal double-loop seams automatic welder to replace a tradition solder of arc of tungsten pole argon, the monofilament of body of a powerful person and flange solders is the beginning that achieves this one goal, it sets solderer order to body of a powerful person of steel of valve industry small swaged forging, flange is a kind do not have equipment, new technology, new method newly, comfortable solder at batch. Except when having province industry, province, reach solder outside operating the characteristic with technical not high demand, also reduced the harm of intense arc light and poisonous soot to the solderer in the job, reduced labor intensity of the solderer greatly, improved working environment, make solder deliver a child produces efficiency to raise 3 ～ 4 times. Solder the machine tool operates simple, maintenance to go to the lavatory, have taller craft stability, rose to solder significantly quality. Produce and use of this equipment solder for valve industry the domain provided good development space, make body of a powerful person and flange are combined solder the leap with quality qualitative generation, be worth to be popularized energetically and be used.
