Conduit of hollow open type is prefab welder makes a station

Develop as the high speed of our country economy, insecurity of the sources of energy, each industry such as petro-chemical, liquid gas, boiler and power station also forms dimensions to change development, drove the development of relevant and other industry. Meanwhile, build many duct path, build oil smeltery, ceaseless and contented economy grows the demand to the sources of energy, this makes petro-chemical construction get flying development. In petro-chemical construction, need many piping products, include to be not straight workpiece tubal form in great quantities among them, like bend, flange, 3 wait, sort of the dimension of these workpiece, norms is various, have Bao Bi, large wall, have the stuff such as carbolic steel, stainless steel, they use soldering means and other pipe fitting to have link mostly. Produce efficiency and quality to improve a product, these soldering is to be besides construction site mostly prefab the spot sends to undertake installing again after finishing. Use condition of the conduit in petro-chemical industry abominable and the amount is large, accordingly, prefab production need has conduit taller solder quality and efficiency, this is right solder equipment and craft put forward to compare high demand. The automation with high grade and efficient development solders equipment, having very important sense to raising petrifaction to build efficiency and mass, and having vast market space. Below current petrifaction industry conduit is prefab current situation, domestic and international relevant conduit is prefab solder equipment, and the specific aim product that research and development of my company place designs undertakes elaborating. One, petrifaction industry conduit is prefab solder the current situation 1.

Petrifaction industry conduit is prefab at present industry of construction of our country petrifaction is in the demand that automation solders to develop at full speed, grow day and day to the demand of piping products, this produces manufacturer to be able to offer the conduit prefabrication of a large number of high quality inside short time with respect to requirement conduit. And mostly prefab manufacturer uses our country manual operation applies solder, produce cost not only tall, efficiency is low, and because existence person is an element,still meet, cause a few solder quality problem, the influence produces a progress. In addition, foreign client is right solder the requirement of quality is very slashing, requirement automation solders. Accordingly, be aimed at the actual production situation with at present prefab conduit, more and more manufacturer homes put forward to be able to realize conduit the requirement that prefab and high grade efficient automation solders, this to solder professionally automation equipment production company offerred new task. 2.

Conduit is prefab automation solders facility is primary form (1) the characteristic that rigid structure is aimed at conduit prefabrication, at present domestic and internationally basically two kinds solder mechanical form, one kind is headstock type, another kind of gyro wheel that is the drum on the belt is worn. The graph is shown 1 times for headstock type. This equipment uses straight canal one end chuck kind clamping apparatus clamp manages end, another end uses gyro wheel wearing to prop up undertake soldering. This kind of orgnaization applies to one aspect of the matter to be straight canal, bend of join of other one aspect of the matter, flange or 3 assemble a form. Solder to be able to be carried out in one aspect of the matter only, cannot come true to be in charge of two end to take what bend, flange mixes 3 to assemble a form continuously, integral work efficiency is not very ideal. Graph prefab automation welder makes tubing of box type of 1 the head of a bed the station pursues 2 it is posture of gyro wheel of the drum on the belt. The design intent of this kind of orgnaization is to solve revolving of workpiece of lay particular stress on to make the same score stability, actually, the workpiece circumgyrate with prejudicial to centre of gravity bigger moment is not smooth still, to soldering quality especially the quality of back cover welding line has bigger effect, and solder automation degree is inferior also. Graph 2 on conduit of posture of drum gyro wheel is prefab and automatic welder makes a station (2) solder craft uses welding rod welding electrode normally or by hand solder of arc of tungsten pole argon (TIG solder) back cover, extremely fused gas protects solder (MAG) or the solder that bury arc (SAW) the welder of fill lid side art. (3) control system is current basically all soldering automation equipment uses such as sheet piece machine, DSP, PLC control yuan of parts of an apparatus to come true solder the control of the program, automation rate is not high. 2, new-style conduit is prefab welder makes a station -- prefab welder makes tubing of hollow open type Hua Jiang of the report in the station serves as major solder automation equipment produces manufacturer, always innovating ceaselessly, solder through prefab to already having conduit automation the thorough contrast of actual condition analyses the thorough research of equipment and manufacturing company, with Shanghai conduit installation company gives full cooperation, development goes a new-style pipeline prefab welder -- conduit of hollow open type is prefab welder makes a station. 1.

Design program (1) solder the pipe that craft asks Shanghai conduit installs a company is prefab solder craft solders for manual TIG render, fill of automatic MAG solder covers a range, automation rate is low, make sure render solders hard quality is stable, affected manufacturing efficiency. To solve this problem, the automation that seeking ideal domestic and internationally for long solders equipment, but not if really. My company depends on the technical capability of oneself, with Shanghai conduit installation company begins collaboration, put forward pipe of research and development prefab and automatic solder equipment, have heater TIG or MAG automatic render, heater TIG or the function of side of MAG fill lid. And equipment should get used to workpiece and assembly deviation, the deviation of such as ovality, ply, and the bad side when the deviation place such as the verticality of groove treatment end panel causes a butt joint and clearance are inhomogenous wait for a phenomenon, solder gives eligible welding line. Additional, the clamping apparatus tool that the client still asks to design can realize pipe fitting clip installs two end to solder prefab pipe fitting, after implementation solders, can go to the lavatory to finish work from the discharge on clamping apparatus. (2) the requirement that main solution raises in the light of the client, prefab and automatic welder makes tubing the design of the station takes the following step: It is OK that ① is designed technically the clamp rotator of open, introduce drive of communication servo electromotor, the dependability that solved clip to hold lay particular stress on already and revolving make the same score stability, it is OK to solved workpiece of two fillets pipe fitting again take out from place of clamping apparatus mouth conveniently. ② develops technology of back cover of solder of fast and automatic MAG. ③ uses AVC (arc length dogs) technology, solder in order to assure the stability of the arc length in the process, assure to solder quality, rise solder adaptability. ④ uses advanced control technology, implementation solders the automata of program and parameter. 2.

Equipment function is hollow prefab welder makes open type tubing the station has following functions: (1) the successive or intermittent operation that can undertake side of automatic TIG and MIG solder back cover, lid solders. Because use PLC to had realized programmed control to make, can undertake operating the choice of mode neatly consequently, also can carry out to welding line solder uninterruptedly continuously, yi Ke is used to control the temperature between the layer statified solder. (2) the TIG that can realize the different capable person such as carbolic steel, stainless steel, alloy steel to pledge, MIG/MAG solders. (3) to assembling, the requirement with right group is inferior, the back cover solder of high quality can undertake below the circumstance in the quantity side permission fault and clearance deviation. (4) can get used to most conduit norms, especially conduit of small-bore thin wall (the wall is large for 3mm) solder. (5) soldering when the conduit bend with large requirements big lay particular stress on, can make sure roll is smooth. (6) the operation is simple and reliable, automation rate is high. 3.

If the graph is shown 3 times,equipment forms equipment whole. Prefab welder makes tubing of hollow open type the station basically comprises by the following parts: Graph conduit of type of 3 hollow open is prefab and automatic solder workstation (1) rotator of clamp of hollow open type is main the characteristic is to use torque of high accuracy, constant to communicate servo electromotor, via low backlash nicety drive of unoccupied place gear of reducer and disappear ages dish of circumgyrate, have unit of a clamp. This tine dish can open through pneumatic, workpiece as string of 1 the clamp after this device locates, the smooth stability when the pipe that contains lay particular stress on in order to assure is rotational. This device (if the graph is shown 4 times) it is the clamp unit that offers for company of Shanghai conduit installation, its can hold a diameter be 460mm with clip most. Graph rotator of clamp of type of 4 hollow open (2) slideway of dragon door type is worn to solder the car offers orbit to reach prop up, use quadrate roof beam sectional, have better tigidity. (3) solder the car is used at coming true to solder the process solders mediumly level and perpendicular motion, can realize arc length below the control of electromotor. (4) solder power source basically includes TIG power source, heater power source and MAG power supply, use device of foreign power source. (5) electronic-controlled the system basically uses PLC and feeling screen to realize corresponding control and operation, the design compares human nature to change. 4.

The advantage is hollow equipment and other conduit are prefab automation solders equipment photograph has following advantages quite: (1) use clamp device to open hoisting to go in from coping, two upright welding line are in charge of to solder after realizing hoisting finish, and do not need workpiece hoisting for many times to adjust, saved work time thereby, improved work efficiency. (2) unique clamp plant design, ensure workpiece won't produce rotate speed because of lay particular stress on flabby, cause solder quality problem. (3) use accurate AVC to dog system, rise greatly solder stability, raised the adaptability that assembles to workpiece at the same time.
