Technical Field
The invention relates to the field of diamond wire cutting, in particular to a deviation guiding device for a diamond wire groove.
Background
Diamond wire cutting is a novel cutting mode and is widely applied to the fields of crystalline silicon, magnetic materials, sapphire and the like, the principle is that a bus is repeatedly wound on a plurality of wire guiding devices to form a plurality of cutting wires for cutting a workpiece and guide wires corresponding to the cutting wires, the guide wires are the rest diamond wires which do not participate in cutting, and cutting is realized through the back-and-forth movement of the whole bus; when cutting, firstly, it is necessary to ensure that the wire grooves of the wire guiding devices on both sides of the cutting surface are linearly corresponding and perpendicular to the feeding direction of the workpiece table, but the winding mode of the diamond wire will determine the guiding wires between two adjacent parallel cutting wires, and an included angle a (as shown in fig. 1) will exist between the two cutting wires, when the distance between the two cutting wires is larger, the included angle a is larger, so that the abrasion to the wire grooves or the falling-off from the wire grooves is more easily caused in the high-speed motion (the included angle between the tangential direction of the wire grooves and the radial direction of the wire guiding roller is 0), the method for reducing the included angle a is to directly lengthen the length of the cutting wires (guiding wires), but the larger the distance between the wire guiding devices at both ends is, the longer the span of the cutting wires is, the wire bow is generated by the self gravity, the vibration generated in the, it causes enlargement of cutting scratches and damage to the wire groove of the guide.
Therefore, in the prior art, the wire arrangement mode in the shape of a Chinese character 'pin' in CN201821632888.0 is generally adopted, and the included angle a is reduced by extending the upper guide wire, but in this mode, the upper wire guide device and the lower wire guide device are arranged in parallel, the included angle a still exists between the wire groove itself and the running direction of the diamond wire, and the problems of wire dropping and rapid abrasion of the wire groove still exist.
Therefore, the present inventors have further studied this and developed a diamond wire groove deflection guide device, which is produced by this.
