Description
Technical field
The utility model relates to the technical field of plant equipment, especially a kind of spot-welding equipment.
Background technology
Spot-welding equipment is the principle that adopts two-sided two point overcurrent welding, during work, two electrode pressurization workpiece make double layer of metal under the pressure of two electrodes, form certain contact resistance, and welding current forms the thermal welding of moment when another electrode at 2 contact resistance points from an electrode stream, and welding current moment from another electrode along two part flows so far electrode form loop, do not injure the internal structure of welded piece.
Yet existing spot-welding equipment structurally still exists certain deficiency, the welding quality of existing spot-welding equipment is poor, and speed of welding is slower, can not meet large-scale spot welding occasion.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for the prior art solving in above-mentioned background technology exists, a kind of spot-welding equipment is provided, and welding quality is good, and speed is fast.
The utility model solves the technical scheme that its technical problem adopts: a kind of spot-welding equipment, comprise soldering tip and the lower soldering tip symmetrical with upper soldering tip, the bottom of upper soldering tip is provided with seaming chuck, the top of lower soldering tip is provided with the push-down head symmetrical with seaming chuck, on upper soldering tip and lower soldering tip, offer respectively circulating cooling groove, on upper soldering tip and lower soldering tip, be jointly connected with resistance welding transformer, the cross sectional shape of upper soldering tip and lower soldering tip is all rectangular, and the cross sectional shape of seaming chuck and push-down head is all isosceles trapezoid.
Further limit: upper soldering tip, lower soldering tip, seaming chuck and push-down head are made by a kind of material in red copper, cadmium bronze or chromium-bronze.
Further limit: the lower surface of seaming chuck parallels with the upper surface of push-down head.
The beneficial effects of the utility model are: a kind of spot-welding equipment of the present utility model, and spot welding principle is simple, and welding quality is good, and speed is fast, and does not injure the internal structure of welded piece.

In figure: 1, upper soldering tip, 2, lower soldering tip, 3, seaming chuck, 4, push-down head, 5, circulating cooling groove, 6, resistance welding transformer, 7, weldment, 8, solder joint.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of spot-welding equipment as shown in Figure 1, comprise soldering tip 1 and the lower soldering tip 2 symmetrical with upper soldering tip 1, the bottom of upper soldering tip 1 is provided with seaming chuck 3, the top of lower soldering tip 2 is provided with the push-down head 4 symmetrical with seaming chuck 3, on upper soldering tip 1 and lower soldering tip 2, offer respectively circulating cooling groove 5, on upper soldering tip 1 and lower soldering tip 2, be jointly connected with resistance welding transformer 6, the cross sectional shape of upper soldering tip 1 and lower soldering tip 2 is all rectangular, and the cross sectional shape of seaming chuck 3 and push-down head 4 is all isosceles trapezoid.
Wherein going up soldering tip 1, lower soldering tip 2, seaming chuck 3 and push-down head 4 makes by a kind of material in red copper, cadmium bronze or chromium-bronze.The lower surface of seaming chuck 3 parallels with the upper surface of push-down head 4.
As shown in Figure 2, the spot-welding technology process of this kind of spot-welding equipment is: in setting, soldering tip 1 is top electrode, and lower soldering tip 2 is bottom electrode, open cooling water, two weldment 7 removing surfaces are clean, after assembling accurately, send between top electrode and bottom electrode, exert pressure, make its contact good, energising is heated the surface that is in contact with one another of two weldments 7, and local melting forms nugget, after power-off, keep pressure, make nugget cooled and solidified under pressure form solder joint 8, remove pressure, take out two weldments 7.
220V alternating current is become to low-voltage, and the power supply of large electric current, can be also can exchanging of direct current.Voltage drop after welding rod ignites, except 220/380 voltage transformation once, secondary coil also has tap-change voltage.
The inductance value of spot-welding equipment can produce huge voltage change when switching on and off, and the high-temperature electric arc that utilizes positive and negative polarities to produce when instantaneous short circuit carrys out scolder and the materials to be welded on consumable electrode, reaches the object that makes their combinations.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
