Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The step of a kind of method producing B alloy wire Wiegand effect of the present invention includes the B alloy wire at the uniform velocity advanced first is carried out heat treatment, then carries out traction localization process, after carry out deformation process. B alloy wire through traction location is bent to spiral state by deformation process.
Heat treatment process: adopting accurate speed governing and temperature control, involutory spun gold carries out the pre-heat treatment. That this link processes it is crucial that want the outer oxide layer of involutory spun gold to be removed, eliminate simultaneously and coil the internal stress that packaging alloy silk is formed. The temperature of annealing device controls a certain temperature between 800 DEG C��1200 DEG C, is allowed a choice according to required B alloy wire performance difference, and B alloy wire at the uniform velocity travel rate is 0.1��5m/min. Heating adopts high-frequency heating mode to carry out, and compared with the heat radiation of common heating rod, B alloy wire surface and inner core have bigger temperature difference. While heating, device inner chamber is filled with noble gas, to prevent B alloy wire from aoxidizing.
Deformation process: B alloy wire at the uniform velocity travel rate is 0.1��5m/min, by the deformation block highly fixed. After deformation block, B alloy wire subsequent path can with the angle of path formation one 155 �㡫175 �� before. Owing to B alloy wire surface temperature is higher than inner core, forming the magnetic property that surface is different with inner core when machining, form semi-hard magnet state, B alloy wire can bend to spiral-shaped simultaneously. The diameter of recycling round is 2��4 times of spiral shell footpath, with ensure that B alloy wire receives to coil stress minimum.
Being loaded in earthenware by the B alloy wire of bending, B alloy wire can be stretched directly. There is the change of magnetic property according to magneto mechanical effect in the B alloy wire after deformation, the change in the present invention is precisely forward, therefore greatly improves the performance of sensor.
The embodiment of a kind of method producing B alloy wire Wiegand effect of the present invention is as follows:
