Description
Technical field
The utility model belongs to arc welding or TURP cuts technical field, is specifically related to produce the device of ignition voltage or stable arc and is used for spot welding, seam weldering or the electrode of cutting and the auto-feed of work.
Background technology
The Welding Problems of copper product and Cu alloy material studies show that, the welding of copper product and the Cu alloy material difficulty of comparing with the welding of common metal material is bigger.Its main cause is that thermal conductivity, the coefficient of expansion, the shrinkage ratio of copper product and Cu alloy material is more special, and they all are little functions of temperature, change along with variation of temperature.Under normal temperature condition, the thermal conductivity of copper product is more than 7 times of ferrous material, and under hot conditions, the thermal conductivity of copper product is more than 11 times of ferrous material.Under normal temperature condition, the coefficient of expansion of copper product is more than 7 times of ferrous material, and under hot conditions, the coefficient of expansion of copper product is more than 11 times of ferrous material.When welding, the heat of welding job point passes to bigger zone from solder joint rapidly, and the temperature of welding job point is descended rapidly, is difficult to guarantee the operating temperature of pad, and forms rosin joint and leak weldering, has influence on welding quality.
On the other hand, the thermal coefficient of expansion of copper is bigger, because temperature raises rapidly, produces bigger dilatancy at welding job point, and swelling stress makes the welding position crack.When welding back pad temperature descended, because the thermal conductivity height of copper, radiating rate was fast, and soldered copper spare welding position sharply shrinks, and shrinkage stress makes the welding position crack, and has influence on welding quality.
The main making material of solar heat-collection plate water heater is copper coin material or copper alloy plate, the solar heat-collection plate water heater does not have special-purpose welding equipment, still adopt existing device for ultrasonic welding to weld, because the Welding Problems of copper product and Cu alloy material is not solved completely, this solar thermal collector occurs crackle in use for some time even sealing-off, drainage occur, waste water resource, influenced environmental sanitation, influenced the normal use of solar water heater.The technical problem that current solar heat-collection plate technical field of water heaters presses for solution is the solder technology problem that solves copper product or Cu alloy material.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of above-mentioned copper product or Cu alloy material welding equipment, provide a kind of reasonable in design, simple in structure, easy and simple to handle, automaticity is high, welding effect good, the continuous automatic control melting welding of solar heat-collection plate equipment.
Solving the problems of the technologies described above the technical scheme that is adopted is: support is provided with workbench and motor cabinet, the straightener that motor cabinet is provided with motor and connects with motor, the feeding roller frame that feeding roller is installed is set on workbench, the bracing frame that electric torch is installed is set between straightener on the workbench and feeding roller frame, electric torch is connected with high-frequency current generator, links by conduit and gas cylinder by lead, and the workbench lower support is provided with the controller that is connected with high-frequency current generator by cable and motor.
Controller of the present utility model is a Programmable Logic Controller.
The utility model has adopted the welding current of Controlled by Programmable Controller electric torch, controls the speed of service of soldered copper coin material or copper alloy plate, realizes welding control automatically.Adopt after the utility model welding the solar heat-collection plate water heater after tested, sealing is good, and is above on probation through half a year, drainage do not occur, result of use is good.The utlity model has reasonable in design, simple in structure, easy and simple to handle, automaticity is high, welding effect good, the advantages such as workpiece deformation is little after the welding, can be used for the welding of copper coin material or copper alloy plate.
