Abstract
An ultrasonic welding machine for aluminum resistors comprises a framework. A transformer is mounted on the framework, a workpiece holding platform, a cylinder and an ultrasonic generator are disposed above the framework, the cylinder, the ultrasonic generator and a second welding electrode are connected, and a first welding electrode and the second welding electrode are connected with the transformer by buses. The ultrasonic welding machine for aluminum resistors can provide sufficient current for instantly welding a workpiece (aluminum) on a welding surface, an oxide layer on the surface of the aluminum can be removed instantly during welding, and accordingly the aluminum is welded extremely firmly. In addition, the welding electrodes are made of copper and tungsten alloy and are long in service life, and accordingly the aluminum can be well welded in a natural environment.
Description
Technical field
The utility model relates to big part aluminium welding technology field, is specifically related to a kind of ultrasonic aluminium resistance welding machine.
Background technology
In welding, utilize the more of ultrasonic and resistance welded both at home and abroad separately, and can only weld undersized aluminium for big part aluminium.The fusing point of aluminium is 660 degrees centigrade, and aluminium material surface also can generate oxide-film in natural environment, and this oxide-film can not use the method for adding auxiliary agent to remove, and also be difficult to remove with general physical method, and the fusing point of this layer oxide-film reaches more than 2000 degree centigrade.This just requires temperature that enough big electric currents make two workpiece (aluminium) solder side to reach the fusing point of aluminium in moment, causes common resistance welded very easily to form rosin joint even does not weld.There is following defective in common resistance welder:
1, the electric current that workpiece (aluminium) was melted in solder side moment can not be provided.
2, can not remove the aluminium material surface oxide layer in the moment of welding and cause welding rosin joint to occur even do not weld.
3, the easy adhesion workpiece of welding electrode causes welding electrode quite short service life.
4, can not in natural environment, realize welding.
Summary of the invention
The purpose of the utility model be to provide a kind of in natural environment to the aluminium good welds, electrode life is long, the ultrasonic aluminium resistance welding machine that welding quality is high.
The purpose of the utility model is achieved in that a kind of ultrasonic aluminium resistance welding machine; Comprise frame; Transformer is installed on the frame, and the frame top is provided with first ultrasonic head and second ultrasonic head of workpiece placement station, cylinder and supersonic generator, and cylinder is connected with second ultrasonic head and second welding electrode; First welding electrode is connected with transformer through bus with second welding electrode, and first welding electrode and second welding electrode adopt copper-tungsten to process.
The ultrasonic aluminium resistance welding machine that the utility model provides has following beneficial effect:
1, the electric current that workpiece (aluminium) was melted in solder side moment can be provided.
2, can moment of welding the aluminium material surface oxide layer remove cause welding very firmly.
3, the material that adopts of welding electrode is a copper-tungsten, and long service life can be implemented in the natural environment good welds to aluminium.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The utility model comprises frame 1; Transformer 2 is installed on the frame 1, and frame 1 top is provided with first ultrasonic head 4 and second ultrasonic head 7 of workpiece placement station 9, cylinder 8 and supersonic generator 12, and cylinder 8 is connected with second ultrasonic head 7 and second welding electrode 6; First welding electrode 5 is connected with first ultrasonic head 4 and is fixed, and first welding electrode 5 is connected with transformer 2 through bus 3 with second welding electrode 6.First welding electrode 5 and second welding electrode 6 adopt copper-tungsten to process.
The course of work of the utility model is following: be placed on two aluminiums 10 and 11 on the workpiece placement station 9; Start the welding button; Cylinder 8 promotes welding second welding electrode 6 and second ultrasonic head 7, has applied certain pressure (adjustable) so just for two workpiece, makes two aluminium solder side excellent contact.Cylinder 8 puts the back sensor in place to signal of cyclelog; Cyclelog starts supersonic generator, lets first ultrasonic head 4, second ultrasonic head 7 start working, and makes ultrasonic wave be delivered to aluminium; Transformer 2 energising applies big electric current for two aluminiums to begin welding then; Transformer 2, first ultrasonic head 4, second ultrasonic head 7 quit work in succession and got into the dwell time (dwell time is electrodeless adjusting) to the back weld interval, and the dwell time resets to cylinder 8, the welding process of completion aluminium.All welding process adopts programme-control.
