Description
Technical field
The utility model relates to plants tack welding machine and mash welder, is specifically related to a kind of hand-held active control type and plants nail mash welder.
Background technology
Automobile technology of today, in order to pursue fuel-efficient, energy-conservation, subtract carbon, light-weighted development is trend of the times, and each depot is invariably in new car money, use aluminium alloy or extra-high tension steel reduces car weight, and the use of above-mentioned two kinds of new materials brings brand-new challenge also to automobile repairing equipment.The progress of extra-high tension steel, can with thinner lighter sheet metal, obtain and compare the identical or higher bus body strength of conventional iron vehicle body, this material when welding due to the reduction of sheet metal thickness, what demand was less enters heat, avoids sheet material to be out of shape because of overheated, once it is too high to enter heat, sheet material is also easy to oxidation, easily produces corrosion problem after welding.The sheet metal thickness of current conventional iron vehicle body is about about 0.8 ~ 0.7mm.Nissan Motor also announced in 2013 before 2017, the extra-high tension steel application percentage of listing new car to be promoted to 25%, to be expected to reduce car weight when the time comes and reach 15%, and protect exhibition at the Frankfurt, Germany vapour of 2014, hearsay about the extra-high tension steel of a new generation of germany volkswagen company is also growing, and it is thick that it claims following sheet metal thickness to reach 0.3mm.For thinning wagon sheet, traditional welding method will face great challenge, when tackling the material of a new generation like this, time during welding must be short in as far as possible to reduce into heat and output current, otherwise easily make that sheet material heat affected area is large, overheated, rotten, corrosion, destroy panel stiffness and vehicle body security.
At present, conventional welding equipment comprises resistance type spot welder (repairing for iron vehicle body) and condenser type plants tack welding machine (repairing for aluminium vehicle body).
With reference to Fig. 1, resistance type spot welder comprises power input, power model, control module, main transformer 11, two outputs of main transformer 11 are respectively as welding gun 12 and ground wire 13, wherein, power model can use the switching device such as A.C. contactor or bidirectional triode thyristor to realize conducting and the disconnection of main transformer 11 primary side, if use A.C. contactor, then main transformer 11 can use tapped transformer to arrange in pairs or groups band switch to adjust output current; Control module part, after setting welding current and weld interval parameter by user, give power stage triggering command, then control module is to power model drive singal.The shortcoming of current resistance welder is on the market as follows: 1. volume is large, Heavy Weight, and integrated level is low, cannot be hand-held, and portability is poor; 2., except main frame also needs welding gun and ground wire, the cable of welding gun and ground wire is thick and heavy, and not only cost is high, and the scope of activities of operation also limits by cable length; 3. input current is large instantaneously, higher to grid requirements, therefore substantially cannot be used for the single-phase use of 110V; 4. the output energy in the unit interval is lower, therefore weld interval is long, to mother metal to enter heat large, heat affected area after welding is large, easily make that sheet material heat affected area is large, overheated, rotten, corrosion, destroy panel stiffness and vehicle body security, this phenomenon is more outstanding when plate sheet welding, is difficult to apply on the vehicle body of extra-high tension steel work; 5. exchange and export, AC impedance consume is large; 6. be limited to moment power output lower, be difficult to carry out aluminium and plant nail welding, therefore cannot repair aluminium vehicle body.
With reference to Fig. 2, current condenser type is planted tack welding machine and is comprised power input, charging transformer 21, rectifier 22, charging controllable silicon 23 and charging resistor 24, electrolytic capacitor 25, discharging thyristor 26, control module, two outputs of electrolytic capacitor connect welding gun 27 and ground wire 28 respectively, discharging thyristor 26 is arranged between electrolytic capacitor 25 and welding gun 27, control module part, charging voltage is set by user, control module drives charging controllable silicon 23 to charge to electrolytic capacitor 25, control module possesses voltage detection circuit, if capacitor does not reach setting voltage, then charge, if exceed setting value, discharge resistance is then used to discharge, if receive power stage triggering command, then stop charging, and change and discharged by electric discharge controllable silicon 26.The shortcoming of current capacitive battery welding machine on the market has: 1. volume is large, Heavy Weight, and integrated level is low, cannot be hand-held, and portability is poor; 2., except main frame also needs welding gun and ground wire, the cable of welding gun and ground wire is thick and heavy, and not only cost is high, and the scope of activities of operation also limits by cable length; 3. instantaneous output current is large, output time is extremely short, but because the half control assembly using controllable silicon such is as discharge switch device, make output time uncontrollable, carrying out plate sheet welding, as super high tensile steel plate weld time, otherwise power output excessive cause to crack down evil force punch, otherwise power output is too low causes not prison welding, success rate is low; 4. in order to offset the consumption of the output cable such as welding gun, ground wire, must adopt many large-scale electrolysis Capacitance parallel connections, capacitance is large, and because constrained input electric current during discharge and recharge is large, therefore discharge and recharge resistance volume is large and caloric value is high, and energy consumption is large; 5. be limited to output time uncontrollable, be difficult to carry out iron meson spot welding function, therefore cannot repair iron vehicle body.
Because the output current of capacitive battery welding machine can reach kilo-ampere, much larger than full control assembly---the maximum current of FET (MOSFET) conventional at present, control according to FET, must by multiple FET parallel shunt, but existing machine structure and technique can not realize the equilibrium shunting of FET, FET is easily made to burn, therefore, the half control assembly SCR control electrolytic capacitor discharge and recharge that existing capacitive battery welding machine only adopts overcurrent larger.
Current resistance type spot welder and condenser type are planted tack welding machine and be there is respective shortcoming respectively, be difficult to the materials such as compatible iron, aluminium, high-tensile steel, namely the requirement meeting automobile maintenance industry future is difficult to, therefore, developing a kind of new welder that can adapt to iron, aluminium, the welding of extra-high tension steel, is Automobile Service field problem demanding prompt solution.
