Description
Technical field
The utility model relates to a kind of resistance welder, relates in particular to a kind of large power energy storage bonding machine.
Background technology
As shown in Figure 1, when welding compressor housing and air intake duct, because this workpiece is circular welding, the welding requirements sealing is more intense, and bonding area is bigger, and housing need bear certain pressure when welding.
Consistent powerful single phase ac welding machine or the phase secondary rectification welding machine of adopting of traditional welding manner: all there is shortcoming in this this welding to this workpiece welding:
1. plant capacity is big, and transmission network load difficulty has adverse influence to the normal operation of electrical network.
2. single phase ac electric resistance welding machine is big because of the welding circuit reactance, and power factor has only about 40%, and energy loss is big, and is not energy-conservation, uneconomical.
3. it is long to weld the required time, and the heat affected area is big, and welding work pieces is easy to generate distortion.
4. it is long to weld the required time, and it is long to conduct the hot time to peripheral metal, and heat loss is many, and general heat loss accounts for about the 30%-50% of total amount of heat, and the heat great majority that welding produces have been done idle work.
When the welding discharge, the heat that the resistance of metal body produces welds joint makes metal produce moulding state, and pressure required when at this moment welding pushes, and the crimp of generation is shunk freely nugget and become closely knit.The fusing core is to begin to cool down crystallization in the metal " shell " of sealing, shrinks not free.If do not have the pressure effect this moment, solder joint is prone to shrinkage cavity and crackle, influences weld strength.Because weld interval is longer, in the long time, the probability of extraneous factor affecting pressure increases, and remote-effects metal solder quality increases greatly, concerning workpiece, directly influences the sealing of compressor assembly.Therefore the new welder of inventing a kind of suitable compressor housing welding is highly profitable.
The utility model content
Technical problem to be solved in the utility model is exactly the defective that exists at existing resistance welder, and a kind of large power energy storage bonding machine is provided, and it has solved existing resistance welder causes rush of current easily to electrical network problem.
The technical solution of the utility model is achieved in that it comprises resistance welding machine, welding circuit and welding gas circuit, resistance welding machine comprises a support, one side of support is fixed with weld cylinder, the bottom of weld cylinder is fixed with portal frame, on the portal frame, following corresponding top electrode and the bottom electrode of being equipped with, the welding gas circuit comprises a gas storage bag, the entrance point of gas storage bag is connected with source of the gas, the port of export connects pressure regulator valve and is connected with two-position-five-way solenoid valve, two-position-five-way solenoid valve connects into the circulation air supply system with a times strength cylinder, it is characterized in that: between the outlet of the port of export of gas storage bag and two-position-five-way solenoid valve, be connected with a branch road, two position two-way valve and check valve are housed on the branch road.
Principle of the present utility model is that jumbo electric capacity at first charges, and moment discharges to welding transformer fast then, and the pulse high current of generation welds workpiece, whole welding process was finished in 3 ‰ seconds, made surperficial solderless trace, need not polish, reduce manufacturing procedure, enhance productivity.The condenser discharge welder fundamental diagram as shown in Figure 2.Discharge with the energy-storage capacitor group, the resistance power supply of energy is provided to welding, meaning condenser discharge resistance welding power supply, the networking single phase ac is charged to capacitor group C after the fairing rectification, during welding, IGCT VTH conducting, C obtains the pulse welding current that a peak value is big, the time is short to a winding discharge of welding transformer T in secondary one side, and switch S is a change-over switch, for the current transformation direction of leading to welding transformer T, magnetic saturation to prevent the unidirectional energising of transformer.VD is a fly-wheel diode.
The utlity model has following advantage:
A) with energy-storage capacitor group discharge, provide the resistance welding power source of energy to welding, absorb energy from network before the welding machine weldering, with less current and long time to capacitor charging storage.Then stop mains supply in the welding process, avoided as mains frequency resistance welding machine, electrical network being caused rush of current.Therefore, can reduce requirement to the mains supply capacity.Adopt the three phase mains power supply with the welding machine demanded power output when big, use producer's power supply grid load evenly.
B) percussion welder need not be considered induction reactance because of being output as near direct current, and its power output is near active power, and power factor plays good energy-saving effect like this up to 95%.
C) large power energy storage weldering whole welding process was finished in 3 ‰ seconds, and the heat affected area is little little to welding work pieces generation distortion.
D) in the welding process, electric capacity discharges rapidly, and waveform is precipitous, and concentration of energy does not have the batch process of alternating current zero passage, and sweating heat efficient height is easy to regulate and control, thereby can weld physical property or thickness than the structure that differs greatly.
