Technical field
This utility model relates to a kind of magnetic field generation device, more particularly to the permanent magnetism uniform magnetic field generator used in magnetic induction free abrasive saw blade cutting.
Background technology
In recent years, along with Solar use increases, the development of photovoltaic industry, the demand of silicon chip is sharply increased.Silicon crystal size increases, and slot length and the degree of depth increase, and in wire sawing process, abrasive particle is difficult to enter in long and deep joint-cutting, and free abrasive saw blade cutting ability reduces.Magnetic induction free abrasive saw blade cutting is that ferromagnetism saw silk is vertically arranged in uniform magnetic field, makes the magnetization of saw silk around form high-gradient magnetic field, and magnetic abrasive grain by suction, thus brings the more abrasive particle of cutting zone in high-gradient magnetic field, improves cutting efficiency.Ferromagnetism saw silk is placed in uniform magnetic field four regions of formation around saw silk, is divided into Liang Ge paramagnetic district and two inverse magnetic regions, as shown in Figure 1.Utilizing paramagnetic district that paramagnetism abrasive particle produces suction, inverse magnetic region produces repulsion to paramagnetism abrasive particle, thus reduces again width of slit while improving cutting efficiency.
Summary of the invention
In order to overcome the deficiency that cannot provide uniform magnetic field in existing magnetic induction free abrasive saw blade cutting, this utility model provides one and can apply to magnetic induction and dissociate magnetic field generation device in saw blade cutting, under outside uniform magnetic field auxiliary, saw the high-gradient magnetic field that can form four regions around silk, improve cutting efficiency and reduce width of slit.
This utility model solves its technical problem and be the technical scheme is that
Magnetic field generation device based on magnetic circuit in a kind of magnetic induction free abrasive saw blade cutting, including magnetic pole, 6 block permanent magnets and 3 pieces of yokes, for the processing stations of magnetic induction free abrasive saw blade cutting between the upper end of two magnetic poles, the upper end opposite face of said two magnetic pole is opposite sex polarity respectively, the lower end of described magnetic pole, lower front side and lower rearward side polar surface with 1 block permanent magnet respectively is connected, described permanent magnet is identical with place pole polarity with the polarity of magnetic pole contact surface, two between the polar surface of the permanent magnet of magnetic pole lower end, two between the permanent magnet polarity face of magnetic pole lower front side, two are connected by 1 piece of yoke between the permanent magnet polarity face of magnetic pole lower rearward side respectively.
Further, the bottom surface that is positioned at the permanent magnet of magnetic pole lower front side, the permanent magnet being positioned at magnetic pole lower rearward side bottom surface all with the bottom surface of described magnetic pole at grade.
Technology of the present utility model is contemplated that: add auxiliary uniform magnetic field generator in free abrasive saw blade cutting, be combined with high permeability material by permanent magnet, have volume little, can by changing permanent magnet and yoke regulation magnetic field intensity, safety is high, be prone to and the advantage such as lathe is combined.The combination of permanent magnet is placed, and improves the magnetic field intensity produced between magnetic pole.Ferromagnetism saw silk is placed between magnetic pole in the uniform magnetic field produced, and saw silk magnetization produces high-gradient magnetic field, improves cutting efficiency and reduces width of slit.
The beneficial effects of the utility model are mainly manifested in: saw the high-gradient magnetic field that can form four regions around silk under outside uniform magnetic field auxiliary, improve cutting efficiency and reduce width of slit.
