Description
Technical field
The present invention relates to a kind of resistance spot weld and welding operation method thereof, belong to the mash welder design field.
Background technology
Welding refers to through heating, pressurization or both combinations and makes of the same race or xenogenesis weldment between atom, set up, form the technology of permanent connection.For metal solder, generally adopt electric resistance welding, so-called electric resistance welding; Exactly weldment is placed between two electrode holders; When electric current passed through two electrode holders and weldment, weldment was big because of resistance, and the resistance heat effect causes the weldment temperature constantly to rise; When temperature rises to the plasticity state, under the effect of two electrode holder pressure, connecting as one between weldment and the weldment.When adopting said method to carry out bit copper, because copper has good electric conductivity, rapid heat dissipation, resistance is less, and the welding between copper tool and the copper tool can't realize.And in actual mechanical process, two electrode holders are owing to switch on for a long time, and temperature is higher, and long-term high temperature has reduced the service life of electric clamp.The mode that the primary voltage that simultaneously existing resistance welding machine control size of current generally all is employing is regulated, regulating effect is undesirable.
Summary of the invention
The present invention is exactly to above-mentioned prior art problem, the resistance spot weld and the welding operation method thereof that provide a kind of welding, electric clamp high life, secondary voltage of effective realization copper to regulate.
The present invention is achieved in that a kind of resistance spot weld; Comprise casing, casing is provided with cylinder, top electrode anchor clamps, bottom electrode anchor clamps, cylinder adjuster, and cylinder adjuster, top electrode anchor clamps are connected with cylinder; Be provided with synchrotrans in the casing; It is characterized in that described top electrode anchor clamps are hollow, the top electrode anchor clamps are provided with water inlet and delivery port, and described water inlet is connected with water pump through water pipe; Also be provided with bidirectional triode thyristor in the described casing, synchrotrans are connected with bidirectional triode thyristor, and bidirectional triode thyristor is connected with top electrode anchor clamps, bottom electrode anchor clamps respectively through conducting copper belt; Also be provided with controller in the described casing, controller is connected with synchrotrans, bidirectional triode thyristor; Described casing is provided with data manipulation controller, the floor push of band display screen, and data manipulation controller, floor push are connected with the interior controller of casing.
One deck insulating tape is twined in the exposed section on the described conducting copper belt.
A kind of welding operation method of resistance spot weld, its characteristic may further comprise the steps:
Step 1, open pump switch, make water constantly from power on the anchor clamps water inlet get into, flow out from delivery port, constantly to the cooling that circulates of last electric clamp;
Step 2, with needing weld to coat the high scolder of resistance value between two or more weldments;
Step 3, the weldment that will add scolder are put between top electrode anchor clamps, the bottom electrode anchor clamps;
Step 4, unlatching cylinder adjuster, top electrode anchor clamps downward electrode holder direction under the promotion of cylinder is depressed, and weldment is clamped between top electrode anchor clamps and bottom electrode anchor clamps;
Step 5, unlatching floor push, electric current is delivered on top electrode anchor clamps, the bottom electrode anchor clamps through conducting copper belt;
Step 6, the current delivery through top electrode anchor clamps, bottom electrode anchor clamps are to weldment; Because the position of the welding of the needs on the weldment scribbles the high scolder of resistance value; Therefore scribbling the scolder place because resistance heat effect temperature constantly raises; When temperature rises to the plasticity state, scribble the scolder place between weldment and the weldment and connect as one;
Step 7, electric current be according to interrupting preset weld interval, shifter cylinder adjuster then, and the top electrode anchor clamps take out welding weldment well at last at the drive of cylinder retraction retraction down.
Described scolder is that carbon dust, pig iron powder and water mix.
Through above technical scheme, in actual moving process, change primary voltage, thereby generate secondary voltage through bidirectional triode thyristor.And the resistance of weldment is certain, and the change through voltage changes welding current.And the present invention adopts the method for synchrotrans, bidirectional triode thyristor secondary transformation; Bidirectional triode thyristor, synchrotrans are connected with controller; Set weld interval, transformation parameter etc. through the data manipulation controller and send instruction, reach regulation voltage and once weld the interruptive current time to controller.
Scribble the high scolder of resistance value at weldment and weldment weld before the welding; During electric current process weldment; At the weld that scribbles scolder because resistance value is high; The weldment temperature constantly rises under the effect of resistance heat effect, and when temperature rose to the plasticity state, weldment and weldment scribbled the effect that scolder is in two electrode holder pressure and connect as one.
Among the present invention, on the top electrode anchor clamps, be provided with water inlet and delivery port, water inlet is connected with water pump through water pipe.Water pump keeps duty always in entire work process, and the top electrode anchor clamps are continual to have water to advance from water inlet, goes out from delivery port, constantly to the cooling that circulates of top electrode anchor clamps.
One deck insulating tape is twined in the exposed section on the conducting copper belt, and is in use safer, and reduces the oxidation rate of conduction bronze medal, improves service life.
In sum, effectively realize the welding of the metal materials that electric conductivity is high, resistance value is little such as copper through the present invention; Secondary voltage is regulated, and size of current more can accurately be adjusted; The cooling of top electrode anchor clamps recirculated water, the service life of having improved the top electrode anchor clamps; Insulating tape is twined in the conducting copper belt exposed section, and is in use safer, and improves the service life of conduction bronze medal.
