Abstract
The utility model discloses a high frequency contravariant spot welder transformer, including transformer skeleton, primary, secondary coil, electric current conductive material and output module, secondary coil adopts the curved system of copper bar to form, and transformer secondary output end connects the radiator, supporting temperature switch and the external fan installed of radiator, temperature switch is used for controlling the start -up of external fan and stopping, through adopting the direct coiling of copper bar to become secondary coil, reduce the intermediate junction link, connect the radiator at secondary output end, install external fan with the radiator is supporting simultaneously, improve the radiating effect, avoid influencing spot welder normal use because of the transformer trouble.
Description
Technical field
The utility model is related to power battery pack mash welder technical field, more particularly to a kind of high-frequency inversion mash welder transformation
Device.
Background technology
Mash welder is the key equipment used in power battery pack welding process, and mash welder system uses two-sided two point excessively stream
The principle of welding, two electrode pressurization workpiece make double layer of metal that certain contact electricity is formed under the pressure of two electrodes during work
Resistance, and welding current forms the thermal welding of moment, and welding current when flowing through another electrode from an electrode in 2 contact resistance points
Moment flow to this electrode and forms loop from another electrode along two workpiece, and will not injure the internal structure of welded piece.
For mash welder, in order to make electrode be produced between high current penetrating electrode and metal in pinpoint welding procedure
The contact resistance of generation realizes spot welding, just must be equipped with reliable direct current output transformer, seems for high-frequency inversion mash welder
Particularly important, not only volume is big for the high-frequency inversion mash welder matching transformer for using at present, and heating is serious, often occurs defeated
Go out the problem of module damage, the normal production of influence.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-frequency inversion mash welder transformer, can effectively contract
Small size, improves radiating effect, improves efficiency.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of high-frequency inversion mash welder becomes
Depressor, including transformer framework, primary coil, secondary coil, current conductive material and output module, the secondary coil are used
Copper bar bends and forms, transformer secondary output output end connection radiator, and supporting installation temperature switch and the external fan of radiator is described
Temperature switch is used to control the startup and stopping of external fan.
The current conductive material is magnetic conduction silicon steel sheet high.
The radiator is gridiron, and external fan is arranged on radiator side.
It is using the beneficial effect produced by above-mentioned technical proposal：Secondary coil is directly turned to by using copper bar,
Reduce intermediate connecting ring section, secondary output end connect radiator, while with the supporting installation external fan of radiator, improve radiating
Effect, it is to avoid because transformer fault influence mash welder is normally used.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein：1st, radiator；2nd, temperature switch；3rd, output module；4th, current conductive material；5th, copper bar；6th, primary coil；
7th, output end.
Specific embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be different from other manner described here using other be implemented, and those skilled in the art can be without prejudice to this reality
Similar popularization is done with the case of new intension, therefore the utility model is not limited by following public specific embodiment.
As shown in figure 1, the utility model discloses a kind of high-frequency inversion mash welder transformer, including transformer framework, just
Level coil 6, secondary coil, current conductive material 4 and output module 3, the secondary coil are bent using copper bar 5 and formed, transformation
Device secondary output end 7 connects radiator 1, and radiator 1 is supporting to install temperature switch 2 and external fan, and the temperature switch 2 is used for
Control the startup and stopping of external fan；The current conductive material 4 is magnetic conduction silicon steel sheet high.
The radiator 1 is gridiron, and external fan is arranged on the side of radiator 1.
During concrete application, the transformer secondary coil involved by the utility model is using the direct bending of red metal plate
Into, intermediate connecting ring section is reduced, simplify structure；Secondary output end is directly connected to radiator, and relevant device when supporting the use again
A low-voltage temperature-controlled fan, better heat-radiation effect are equipped with radiator；Passed as electric current using the high silicon steel sheet of permeability
Material is led, reduce loss improves efficiency.
