The specific embodiment
High energy welding equipment of the present utility model comprises single-chip computer control system 1, main circuit 2, and wherein main circuit 2 comprises power circuit 21, charge circuit 22, discharge loop 23 compositions.
As shown in Figure 1: described single-chip microcomputer (78E58 of WINBOND company) control system 1, it is controlled whole welding process, and its output clamps air cylinder signal, presses down air cylinder signal, capacitor charging control signal, silicon controlled trigger signal, alarm signal.It also can receive condenser voltage sampled signal, the system failure detection signal of input.This single-chip computer control system is by sampling to condenser voltage, and compares with the weldingvoltage of setting, and the result that will compare feeds back to the charging control loop then, thus the control charging.
As shown in Figure 2: described power circuit 21 is by being reserve high power varying dc source E, it can provide the DC voltage of 150V, this power supply E is connected with a high-power MOS tube 211, and this high-power MOS tube 211 is connected with the capacitor charging control signal output pin of single-chip computer control system.Described charge circuit 22 comprises large value capacitor group 222 and capacitance voltage sampling resistor 223, described capacitor group 222 is composed in parallel by the electric capacity of hundreds of thousands of microfarads, this capacitance group in parallel can be stored bigger energy, for bigger welding work pieces, adopt and organize independently charge circuit (isolating mutually between every group) more, discharge loop adopt copolar (positive pole and negative pole) can be simultaneously or timesharing discharge, described large power supply is charged to the capacitor group through metal-oxide-semiconductor control, single-chip computer control system is sampled to the charging voltage on the capacitor by sampling resistor simultaneously, and compare with the weldingvoltage of setting, the result that will compare feeds back to the charging control loop then, and by metal-oxide-semiconductor control charging, the voltage constant that keeps the electric capacity two ends with this process is on setting value.Described discharge loop 23 comprises a high-power one-way SCR 231, contact resistance 232, described controllable silicon 231 is connected with the silicon controlled trigger signal output pin of single-chip computer control system, and described contact resistance 232 contacts with the workpiece of required welding when welding.
When the workpiece of loading onto required welding and press the welding button, system at first cuts off charge circuit, triggers controllable silicon discharge welding then.Whole discharge process is to finish in the mode of snowslide, discharge time is extremely short, be generally 10-50 μ S, energy all concentrated being released on the solder side of moment on the described high power capacitor group, produce huge energy, so that solder side melts, and makes workpiece finish welding process in several milliseconds through the pressure of upper/lower electrode, the voltage on this moment capacitor is released to zero and wait for charging process next time.
Be welded as example with push rod, shaft is prepended to the lateral electrode center, press the clamping button, the clamping cylinder is with the shaft clamping and be in good electrical equipment contact condition, described lateral electrode clamping force is 5000N-20000N, then steel ball is placed the shaft top, air cylinder makes top electrode and steel ball be in good electrical equipment contact condition under starting, and described top electrode clamping force is 5000N-20000N.This moment, two soldering parts were the parts as whole welding circuit, in whole loop, the resistance largest portion concentrates on the contact-making surface, when moment is welded in the controllable silicon discharge, produce huge power attenuation on contact resistance, cause contact-making surface to produce huge heat contact-making surface is melted, the warp immense pressure of air cylinder down merges metal with the rapid compacting of face, meanwhile all energy are also all transferred on the contact-making surface, to finish whole welding process on the capacitor.Release presses down and clamping electrode then, takes off welded piece, and welding machine continues energy storage in order to welding next time.
