Description

Multi-wire cutting auxiliary roller for diamond wires

Technical Field

The utility model relates to a diamond wire-electrode cutting field refers in particular to a many line cutting auxiliary roller of buddha's warrior attendant line.

Background

Diamond wire cutting is a new cutting method, and is widely applied to the fields of crystalline silicon, magnetic materials, sapphire and the like, and cutting of objects is completed by uniformly fixing diamond particles on a high-strength steel wire at a certain distribution density and dragging the diamond wire back and forth at a high speed.

In the multi-wire cutting, the cutting wires are wound on a plurality of wire guiding devices repeatedly through a bus to form a plurality of cutting wires for cutting the workpiece and guiding wires corresponding to the cutting wires, the guiding wires are the rest diamond wires which do not participate in the cutting, and the cutting is realized through the back-and-forth movement of the whole diamond wire; during cutting, firstly, the linear grooves of the wire guiding devices on two sides of the cutting surface are required to be ensured to be linearly corresponding and to be vertical to the feeding direction of a workpiece table, but because the winding mode of the multi-wire cutting machine determines the guiding wires between two adjacent parallel cutting wires, an included angle a (shown in figure 1) exists between the guiding wires and the cutting wires, when the distance between the two cutting wires is larger, the included angle a is larger, so that the abrasion to the linear grooves or the falling-off from the linear grooves are more easily caused in high-speed motion, and the method for reducing the included angle a is characterized in that firstly, the length of the cutting wires (guiding wires) is directly lengthened, but the distance between the wire guiding devices at two ends is larger, the span of the cutting wires is longer, wire bows generated by the self gravity of the cutting wires, vibration generated in high-speed motion, and errors correspondingly existing between the linear grooves between the two wire guiding devices can, 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 wire guiding device above and the wire guiding device below are arranged in parallel, and the wire groove itself still has an included angle with the running direction of the diamond wire, and if the included angle a is increased, the wire falling and the abrasion of the wire groove still exist, so the present inventors further study this, and develop an auxiliary roller for cutting multiple wires of diamond wires, and thus the present invention is produced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a many line cutting auxiliary roller of buddha's warrior attendant line, the material thickness scope that can cut is bigger, and the stability of buddha's warrior attendant line operation during the cutting is higher.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

the diamond wire multi-wire cutting auxiliary roller comprises a fixed shaft, wherein a rotating piece rotating relative to the fixed shaft is arranged outside the fixed shaft, and a wire groove is formed in the rotating piece.

The fixed shaft of the wire guiding device can be fixed on the frame of the cutting chamber through the fixed seat, and the wire groove on the rotating piece of the wire guiding device is consistent with the running direction of the diamond wire by adjusting the installation angle.

Further, the rotating piece is a cylindrical shaft sleeve, and a bearing is arranged between the shaft sleeve and the fixed shaft.

When cutting, the diamond wire can drive the shaft sleeve to rotate relative to the fixed shaft, so that the friction force between the diamond wire and the wire groove is reduced.

Further, the shaft sleeve comprises a shaft sleeve inner layer and a shaft sleeve outer layer, two ends of the shaft sleeve inner layer are tightly attached to the bearing, and a gap is reserved between the shaft sleeve inner layer and the fixed shaft; the outer layer of the shaft sleeve is provided with a wire groove.

Furthermore, the rotating piece is a plurality of guide wheels arranged on the fixed shaft, the guide wheels rotate relative to the fixed shaft, and a wire groove is formed in the outer ring edge of each guide wheel.

The guide wheel can be regarded as an independent wire unit obtained by dividing the shaft sleeve, but the principle of the guide wheel is consistent with that of the shaft sleeve.

Further, a connecting piece is arranged between the fixed shaft and the shaft sleeve, and the shaft sleeve cannot rotate relative to the fixed shaft by fastening the connecting piece.

When the wire groove is processed, the shaft sleeve cannot rotate relative to the fixed shaft, so that an adjustable and fastened connecting piece is additionally arranged, and the shaft sleeve cannot rotate relative to the fixed shaft during processing.

After the scheme is adopted, compared with the prior art, the utility model, have following advantage:

on the basis of the existing cutting chamber, the wire guiding device can be applied without major adjustment, the problem of cutting stability can be really solved when multi-wire cutting is carried out, the friction loss between the diamond wire and the auxiliary wire guiding device is reduced, the size range of the material which can be cut is large, and the thickness of the material is thicker than that of the slice of a common multi-wire cutting machine.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 2, the diamond wire multi-wire cutting auxiliary roller comprises a fixed shaft 1 which can be arranged in a cutting chamber of a cutting machine, a cylindrical shaft sleeve is arranged outside the fixed shaft 1, bearings 2 are arranged between the shaft sleeve and the fixed shaft 1, the bearings 2 are arranged at two ends of the shaft sleeve, the bearings 2 can prevent the shaft sleeve from generating large resistance when rotating relative to the fixed shaft 1 under the condition that the fixed shaft 1 is fixed, and because the shaft sleeve is provided with a wire groove, if the shaft sleeve can rotate along with the diamond wire during the operation of the diamond wire, the friction force between the shaft sleeve and the diamond wire is reduced.

Preferably, the shaft sleeve comprises a shaft sleeve inner layer 3 and a shaft sleeve outer layer 4, two ends of the shaft sleeve inner layer 3 are tightly attached to the bearing 2, and a gap is reserved between the shaft sleeve inner layer 3 and the fixed shaft 1; the outer layer 4 of the shaft sleeve is provided with a wire groove, and the scheme is easier to realize during processing.

As shown in fig. 3, the diamond wire multi-wire cutting auxiliary roller comprises a fixed shaft 1 which can be arranged on a rack fixed seat 7, based on the same idea, after a shaft sleeve is divided, an independent wire unit, namely a guide wheel 5, is obtained, and after the independent guide wheels 5 are arranged on the fixed shaft 1 in parallel, a similar effect is obtained, a bearing (not shown in the figure) is arranged between each guide wheel 5 and the fixed shaft 1, a wire groove is arranged on the outer ring edge of each guide wheel 5, and the guide wheels 5 can be driven to rotate through the diamond wires.
