Abstract
The utility model relates to the technical field of a resistance welding machine, in particular to a double-electrode resistance welding machine comprising a power supply, a controller, left and right welding electrodes and a cylinder, wherein the power supply is connected with the controller which is respectively connected with the left and right welding electrodes and alternately supplies power for the left and right welding electrodes. By adopting the single power supply and the single controller and utilizing the controller to alternately supply power for the two welding electrodes, the production cost can be lowered, and the welding quality can be ensured at the same time.
Description
Technical field:
The utility model relates to the resistance welder technical field, particularly the bipolar electrode resistance welder.
Background technology:
Traditional bipolar electrode resistance welder, pattern is many to export two arrays of electrodes to based on two groups of independent current source controllers and transformer output or single supply controller single phase transformer, preceding a kind of connected mode is equal to two equipment amalgamations, volume can not reduce, and manufacturing cost not only there is not reduction high all the better, more produces the location layout that has limited high-power transformer in the two arrays of electrodes position and increases the problem that connects difficulty; A kind of connected mode in back, being subjected to two electrodes resistance value the time can occur in welding differs and causes the both sides welding electrode shunting energy imbalance to occur, have a strong impact on welding quality, so there is different shortcomings in existing two kinds of structures, being difficult to realizes reducing cost drops into and can make stable output again, and then guarantees the requirement of welding quality.
The utility model content:
The purpose of this utility model is to provide the bipolar electrode resistance welder at the deficiencies in the prior art, and it can guarantee the product welding quality, and can reduce production costs, and result of use is better.
For achieving the above object, the utility model adopts following technical scheme:
It comprises power supply, controller, left and right welding electrode, cylinder, and power supply connects controller, and controller connects left and right welding electrode respectively and to left and right welding electrode interleaved power.
Described welding electrode comprises that conversion copper billet, soldering tip connect copper billet, and cylinder is connected with the conversion copper billet, and the conversion copper billet is connected with power supply.
Described cylinder is connected by universal joint with the conversion copper billet.
Described conversion copper billet is connected copper billet with soldering tip contact-making surface is the silver-colored plane of edge.
Described controller connects left welding electrode and backhand welding receiving electrode respectively.
The beneficial effects of the utility model are, adopt single supply, single controller, utilize controller to two welding electrode interleaved powers, can either reduce production costs, and can guarantee welding quality again, and result of use is better.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
1---power supply,
2---controller,
3---cylinder,
4---the conversion copper billet,
5---soldering tip connects copper billet,
6---universal joint;
7---left welding electrode;
8---the backhand welding receiving electrode;
9---installing plate.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See accompanying drawing 1, the utility model comprises: power supply 1, controller 2, left and right welding electrode 7,8, cylinder 3, left and right welding electrode 7,8 is fixed on the installing plate 9, power supply 1 connects controller 2, controller 2 connects two welding electrodes respectively and to two welding electrode interleaved powers, certainly, this has guaranteed that also two welding electrodes can connect a transformer jointly.
Described welding electrode comprises that conversion copper billet 4, soldering tip connect copper billet 5, and cylinder 3 is connected with conversion copper billet 4, utilizes the alternating movement of cylinder 3 to drive moving of conversion copper billet 4, realizes changing copper billet 4 and is connected copper billet 5 with soldering tip and replaces deciliter.
Described cylinder 3 is connected by universal joint 6 with conversion copper billet 4.
Described conversion copper billet 4 is connected copper billet 5 with soldering tip contact-making surface is the silver-colored plane of edge.
The soldering tip that described controller 2 connects two welding electrodes respectively connects copper billet 5.
The utility model is via controller 2 control operations, realize that two welding electrodes press required welding work pieces in can be at one time, two soldering tips under the workpiece pressing state are via a controller 2 and power supply alternating discharge, carry out independent welding, secondary is welded as fully independently welding during the process, though two welding electrodes are to press workpiece simultaneously, does not produce shunt influence fully, and with medium frequency inverter DC stabilization output, it replaces transformational structure and can bear up to 60KA and effectively export welding current.
Pass through because the utility model structure need be born the low-pressure welding electric current of huge (60KA), also can change, so brought certain degree of difficulty for design and manufacturing because of contacting friction and resistance value.Constantly carrying out technological improvement and dropping into improvement after the test, collect relevant data, the spy designs cylinder 3 and changes the scheme that copper billet 4 is connected by universal joint 6, be knuckle formula structure and natural to vertical direction, can produce sufficient natural modulability when making welding electrode move to contact position, the contact-making surface of welding electrode adopts planar design in addition, allows its two contact position can produce the contact-making surface that coincide more greatly, reduces resistance.Requirement on machining accuracy to contact component in the production process is higher, and stability is had remarkable advantages.
Example: be applied to combustion gas number of degrees meter, being welded of two gas transmission ports can produce angular distortion because of the traditional handicraft operation; Adopt the utility model welding machine to weld, because two welding electrodes are to press workpiece simultaneously, and can weld by big electric current fast, lower the workpiece deformation degree, so can guarantee workpiece: two mounting pipe are led the distance of shaft centers and the angle of position, lower the on-the-spot problem that the dislocation of number of degrees meter is installed, and production efficiency than tradition monolateral or other welding manner efficient fast again more than.
The utility model is simple in structure, and the work effect is better.
The above only is a better embodiment of the present utility model, and all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, and are included in the utility model patent claim.
