Description
Technical field
The utility model belongs to electronic technology field, relates in particular to a kind of ferromagnetic substance part unrelieved stress and removes circuit.
Background technology
Ferromagnetic substance is in casting, welding, forging and pressing and the mechanical cutting course of processing; Owing to the distortion of expanding with heat and contract with cold and mechanical force causes; In the inner unrelieved stress that produces of part; Cause part to play pendulum, reduce the dimensional stability and the mechanical and physical performance of part, make part behind finished product, produce distortion because of the release of unrelieved stress in the use and lost efficacy.For eliminating unrelieved stress, traditional process method is to adopt methods such as seasoning, mechanical vibration, artificial inefficacy and thermal life.The time of these methods removal unrelieved stresss is long, and energy consumption is high, and effect is bad, especially for the unrelieved stress poor removal effect of precision component after mechanical workout of coiling (cover) type ferromagnetic substance.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of treatment time of providing is short, energy consumption is low, and the ferromagnetic substance part unrelieved stress that treatment effect is good is removed circuit.
The purpose of the utility model and solve its technical problem underlying and adopt following technical scheme to realize:
The ferromagnetic substance part unrelieved stress of the utility model is removed circuit; Comprise micro-chip, driver module, switch module, LC shunt circuit, rectification module; Wherein: the LC shunt circuit constitutes by coil L is parallelly connected with capacitor C, and micro-chip is connected with the driver module input terminus, and the output terminal of driver module is connected with the switch module input terminus; The output terminal of switch module is connected with the LC shunt circuit, and the rectification module output terminal is connected with switch module.
Above-mentioned ferromagnetic substance part unrelieved stress is removed circuit, and wherein: said coil L is the high strength enamelled wire coiling.
The utility model compared with prior art has tangible beneficial effect, can be known by above technical scheme, and rectification module is transformed to the array direct current with grid alternating current, is respectively remaining circuit suitable WV is provided; The dutycycle that switch module is set according to control module is controlled the power supply of LC shunt circuit, makes coil L produce dither magnetic field; The effect of driver module is that the wave with controlling unit is amplified to the wave that satisfies driving switch module action request; The micro-chip control link is man-machine Interface, sends operational order.The LC shunt circuit is accepted externally fed when switch module is opened, make coil produce magnetic field, feeds the galvanic current of LC, forms the high-frequency current of high frequency magnetic field in LC parallel oscillation process.When switch module cuts off the power supply, lean on the magnetoelectricity exchange in the LC shunt circuit, form high frequency attenuation magnetic field.Unrelieved stress in high frequency attenuation magnetic field removal dish (cover) type ferromagnetic substance part machinery processing; Under the high frequency attenuation the action of a magnetic field; The magnetic domain size changes with the variation of direction with high frequency attenuation magnetic field in the inner spontaneous magnetization of the ferromagnetic substance part zone; Cause the corresponding change of metallic substance microtexture cross-sectional shape, thereby make that metallic substance unrelieved stress plane of action changes, corresponding change also takes place the unrelieved stress of uneven distribution size, direction, cause repeatedly redistribution in uneven distribution state short period of time of unrelieved stress in the material structure; Cancel out each other or weaken in the redistribution process, realize removing fast unrelieved stress.The utility model treating processes time is short, and energy consumption is low, and treatment effect is good.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing is the schematic circuit diagram of the utility model.
Mark among the figure:
1, coil L; 2, micro-chip; 3, driver module; 4, switch module; 5, LC shunt circuit; 6, rectification module.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the ferromagnetic substance part unrelieved stress that proposes according to the utility model is removed embodiment, structure, characteristic and the effect thereof of circuit, specify as after.
Referring to accompanying drawing; The ferromagnetic substance part unrelieved stress of the utility model is removed circuit, comprises micro-chip 2, driver module 3, switch module 4, LC shunt circuit 5, rectification module 6, and wherein: LC shunt circuit 5 constitutes by coil L1 is parallelly connected with capacitor C; Micro-chip 2 is connected with driver module 3 input terminuss; The output terminal of driver module 3 is connected with switch module 4 input terminuss, and the output terminal of switch module 4 is connected with LC shunt circuit 5, and rectification module 6 output terminals are connected with switch module 4.
The coiling of said coil L1 high strength enamelled wire.
When the ferromagnetic substance part unrelieved stress removal circuit of employing the utility model is handled part; Part is under the high frequency attenuation the action of a magnetic field; The magnetic domain high-speed motion makes part produce high heat, for guarantee part not Yin Gaowen cause its mechanical property to change, treating processes should be carried out under the cooling state.Because air is very big to the magnetic resistance of high frequency magnetic field, outside scope apart from 300mm, high frequency magnetic field will disappear totally, can not produce human body and injure.Guaranteeing that operator remove work beyond the circuit 300mm apart from ferromagnetic substance part unrelieved stress, can relievedly use fully.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Any the utility model technical scheme content that do not break away from, all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
