Description
Technical field
The utility model relates to a kind of resistance electric welding machine control cabinet with the reconditioning status function, belongs to welding field.
Background technology
Electric resistance welding is energising when utilizing the electrode soldering turret that soldered thing is applied certain pressure, utilize the Joule heat deposite metal that interelectrode contact resistance produces and reach the purpose of welding.Be connected to electrical network after the elementary windings in series of the current controller of resistance electric welding machine control cabinet with two IGCTs of reverse parallel connection and welding transformer, utilize and trigger control device, make two IGCTs connect power supply in the positive-negative half-cycle of alternating current respectively, change the control angle of flow α of IGCT, just can realize adjusting welding transformer output bonding power.Based on this principle, control cabinet is at unlike material, different-thickness and different structure, by counting and welding current, time and the pressure of each point of the control welding process automatically of programming, realizes the control to welding quality.Improve production efficiency greatly, be widely used in large-scale production manufacturing industry such as automobile, agricultural machinery, household electrical appliances.
But after the prior art welding process, need artificial butt welding clamp electrode contact to carry out reconditioning removing the contact carbon distribution, complex operation, labour intensity is big and efficient is low.
Summary of the invention
The purpose of this utility model provides can carry out the resistance electric welding machine control cabinet that the reconditioning state switches automatically.
Embodiment of the present utility model is: a kind of resistance electric welding machine control cabinet with the reconditioning status function, comprise power supply input and output terminal, control transformer, control power supply, current controller, current detector and welding control panel, described power input terminal is connected with power supply, described power output terminal is connected with welding gun by the peripheral hardware welding transformer, described welding control panel is provided with communication port and links to each other with peripheral hardware programmable device watch-dog, the welding control panel is provided with the TB1 terminal board, and terminal board has 2 groups of 4 magnetic valve SOL1～4 of terminal and peripheral hardware to be connected; Establish a reconditioning state switch boards in going back in the control cabinet; The communication port of described reconditioning state switch boards is connected with the welding control panel by the TB1 terminal board, and its power input terminal is connected with the control power supply, and its switching controls mouth is connected with SOL2 with two peripheral hardware magnetic valve SOL1; Several indicator lamps, button and knob are equipped with in the bottom of described control cabinet, link to each other with the TB1 terminal board with reconditioning state switch boards.
The utlity model has following advantage:, just can finish following three kinds of states and switch: clamp welding (being operate as normal) state in welding control system programming in addition; Only clamp and do not open (be soldering turret normally closed, carry out electrode dressing) state; Only clamp and do not weld (be soldering turret closed but do not have the welding electric current) state.Additional step in the middle of reducing has improved welding job efficient greatly.
Description of drawings
Fig. 1 is the theory diagram of the utility model resistance electric welding machine control cabinet;
Fig. 2 is the utility model resistance electric welding machine control cabinet embodiment electrical schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: as shown in Figure 1, electric cabinet is made up of power supply input and output terminal, control transformer, control power supply, current controller, current detector, welding control panel, reconditioning state switch boards and several indicator lamps, button and knob; Power supply is introduced casing by input terminal, through the current controller unsteady flow, passes current detector, derives casing by lead-out terminal, and with the elementary windings in series of welding transformer, the welding transformer secondary windings is connected with soldering turret, forms main circuit; Control transformer is introduced power supply by input terminal, and output produces low-tension supply and uses for welding control panel and control power supply, constitutes low tension loop; The triggering control section of welding control panel produces triggering signal, the IGCT conducting of power supply stream controller, thus reach the welding current regulation and control, constitute closed-loop control with current detector; The communication interface of welding control panel is connected with peripheral hardware programming watch-dog, finishes control program establishment and storage; 2 groups of 4 magnetic valve SOL1～4 of TB1 terminal board (being equivalent to several I/O interfaces) and peripheral hardware of welding control panel are connected, and wherein: SOL1, SOL2 are the working electromagnet valve, control the soldering turret closure and open, and get welding ready; SOL3, SOL4 are for shrinking magnetic valve, the stroke of control soldering turret.The TB1 terminal board also links to each other with reconditioning state switch boards, and the control power supply is the power supply of reconditioning state switch boards, and the external control terminal of reconditioning state switch boards is connected with described indicator lamp, button, knob; The external control terminal of reconditioning state switch boards and peripheral hardware 2 magnetic valve SOL1, SOL2 link to each other.
After electric welding machine is finished according to the several welding of getting ready of program setting, step below the control cabinet increases the end indicator lamp and lights, just but manual knob switches to the reconditioning state, and 2 magnetic valve SOL1, SOL2 make the soldering turret closure under the control of reconditioning state switch boards, thereby the butt welding clamp electrode carries out reconditioning.Electrode dressing finishes, and knob is switched to duty, removes by SR and gets number ready, recovers normal welded condition, just can continue welding.
Fig. 2 is an embodiment of the present utility model.
