Abstract
The invention relates to two way discharge stored-energy welding machine. It includes stored energy capacitance set and welding transformer of which primary coil one end is respectively connected with the two input ends of the electrical source by controllable silicon D1 and D4; another end is connected by the controllable silicon D2 and D3. The D1, D2, D3, D4 are alternately on state in two adjacent welding. Compared with the one way discharge controlled traditional welding transformer, the invention has smaller volume with same welding condition which can greatly reduce material consumption.
Description
Technical field
The invention belongs to welding equipment, relate to a kind of two-way discharge energy-storage resistance welder.
Background technology
Traditional energy-storage resistance welder, its discharge circuit as shown in Figure 1, it is to the energy capacitance set 1 ' charging that is connected between two inputs of power supply by electrical network, and be stored in energy in the capacitance group by switch to welding transformer 2 ' discharge, at the secondary formation low-voltage, high-current of welding transformer workpiece is welded.Because discharge current is bigger, and belongs to the unidirectional pulse electric current, may cause magnetic saturation when serious, therefore need to design welding transformer greatlyyer, guarantee certain magnetic flux surplus capacity, thereby increased the volume and the material consumption of transformer.
Summary of the invention
Technical problem to be solved by this invention is that a kind of two-way discharge energy-storage resistance welder that can reduce volume of transformer and material consumption is provided.
Two-way discharge energy-storage resistance welder of the present invention includes energy capacitance set and welding transformer that is connected between two inputs of power supply, welding transformer primary coil one end is connected with two inputs of power supply with D4 by controllable silicon D1 respectively, and the other end of welding transformer primary coil is connected with two inputs of power supply with D3 by controllable silicon D2 respectively.In the welding process, make D1 and D2 conducting simultaneously, D3 and D4 conducting simultaneously, and D1, D2 and D3, D4 take turns conducting in twice adjacent welding.
The present invention is owing to control welding transformer by two groups of controllable silicon wheels, change the sense of current that flows to the welding transformer primary coil in turn, like this, before discharge next time, the sense of current of welding transformer can be changed, magnetic flux change be last time welding transformer remanent magnetism and the welding transformer magnetic flux add up, thereby strengthened the flux change amount.Therefore welding transformer not only can magnetic saturation, and can make full use of transformer remanent magnetism, and is corresponding under equal welding condition, and to compare its volume much smaller with the traditional welding transformer of unidirected discharge control, greatly reduces the welding transformer material consumption.
Description of drawings
Fig. 1 is the discharge circuit schematic diagram of traditional energy-storage resistance welder;
Fig. 2 is the discharge circuit schematic diagram of two-way discharge energy-storage resistance welder of the present invention.
The specific embodiment
As shown in Figure 2, include in the discharge circuit of two-way discharge energy-storage resistance welder of the present invention to be connected and be used for the capacitance group 1 of store electrical energy and the welding transformer 2 that is used for carrying out welding job between two inputs of power supply, welding transformer primary coil one end is connected with two inputs of power supply with D4 by controllable silicon D1 respectively, and the other end of welding transformer primary coil is connected with two inputs of power supply with D3 by controllable silicon D2 respectively.In the welding process, D1, D2 and D3, D4 take turns conducting control, thereby realize discharge current positive and negative successively two primary coils to the welding transformer of flowing through on the capacitance group, change the welding transformer remanence direction at every turn.
