Abstract
The utility model discloses electric resistance welding equipment, which comprises a framework, two welding electrodes and power supply devices of the welding electrodes. The two welding electrodes are arranged on the framework, each of the two welding electrodes includes an electrode wheel and a welding rod, the welding rods are fixed onto the framework, the electrode wheels are slidably disposed on the framework in length directions of the welding rods, and the electrode wheels are connected with driving devices which drive the electrode wheels to move. One electrode of the electric resistance welding equipment is fixed while the other electrode is movable, a workpiece does not need to be moved during welding, the lapping size of the workpiece cannot be changed after the workpiece is positioned, welding can be carried out only by means of moving the electrodes, and the quality of the welded workpiece is fine. In addition, a pneumatic key type pressing device is adopted, so that the electric resistance welding equipment is convenient in operation and high in positioning precision. The electric resistance welding equipment is particularly applicable to welding intermediate cylinders of solar inner containers.
Description
Technical field
The utility model relates to a kind of electric resistance welding welding equipment, particularly a kind of electric resistance welding welding equipment that is used for the overlap edge of welding drum shape workpiece.
Background technology
The electric resistance welding process principle feeds the electric current of certain hour simultaneously for to apply certain pressure through the electrode pair welded part, welded part surface is melted and reaches the purpose of welding.
Exist electric resistance welding welding equipment at present when welding operation, two electrodes of welding equipment are fixed, workpiece feeding between two electrodes.In solar energy processing enterprise; When utilizing electric resistance welding welding equipment to weld in the solar energy inner bag tube, need two people to operate, an end of bucket skin in a people is responsible for; Be responsible for the direct of travel and the lap width of bucket skin in the control respectively, lap width mainly is in order to guarantee the diameter dimension of inner bag.Because workpiece needs to move in welding process, lap-joint misplaces in the workpiece movement process easily, and it is unstable to occur workpiece overlap joint size easily.
Because the location dimension of existing electric resistance welding equipment is come manual operation through manual work; The processing dimension of product is wayward and production efficiency is lower; If increase the location in device external, product processing quality promotes to some extent, but is not that final solution need be done further improvement.
Summary of the invention
The problem that the utility model will solve is: a kind of electric resistance welding welding equipment is provided, makes workpiece in welding process, overlap size and can not change.
For addressing the above problem; The utility model comprises frame, be located at two welding electrodes and the electric supply installation of two welding electrodes on the frame; Described two welding electrodes are electrode wheel and welding rod; Welding rod is fixed on the frame, and electrode wheel is slidingly arranged on the frame on the length direction of welding rod, and electrode wheel is connected with the drive unit that the drive electrode wheel moves.
In order to make the workpiece positioning action convenient; And can improve the positioning accuracy of workpiece simultaneously; Described frame is provided with gas control piano type hold down gag, and two piano type pressing plates of gas control piano type hold down gag branch is in the both sides of welding rod top, electrode wheel be positioned at welding rod directly over.
For butt welded seam when welding cools off; Weld seam can be immersed in the water and cool off when making welding; Described frame is provided with the guide rail of level, and electrode wheel is fixed on the slide mass, and slide mass is slidingly arranged on the guide rail; Slide mass is provided with water injector, and the sparge pipe of water injector is positioned at the front side of electrode wheel.
For further butt welded seam cools off; Further improve weldquality; Described welding rod is the water-cooled copper bar, and the water-cooled copper bar is one to have the copper bar of limbers, and copper bar is run through in the limbers on the copper bar length direction; The limbers of water-cooled copper bar is connected with the periodical feeding device, and the water-cooled copper bar is fixed on the frame through the pad axle.
The beneficial effect of the utility model: an electrode of the utility model is fixed, and an electrode moves, and does not need travelling workpiece during welding; Behind the workpiece location; The overlap joint size of workpiece can not change, and just can realize welding through traveling electrode, and the quality after the work welding is good.And adopt gas control piano type hold down gag, easy to operate, setting accuracy is high.The utility model is particularly suitable for welding the middle tube of solar energy inner bag.
