Technical Field

The utility model relates to a but diamond wire cutting substitution wire device is refered in particular to in diamond wire cutting field.

Background

Neodymium iron boron is a permanent magnet with the strongest magnetism at present and is also a rare earth magnet which is most commonly used, the neodymium iron boron magnet is widely applied to electronic products, diamond wire cutting is a new cutting mode and has wide application in the fields of crystal silicon wafers and the like, diamond particles are uniformly fixed on a high-strength steel wire in a certain distribution density, the diamond wire is repeatedly wound on a plurality of wire devices, and the diamond wire is pulled back and forth at a high speed to complete the cutting of objects.

The wire guiding device comprises a wire guiding roller with wire grooves formed in the outer ring, or a plurality of guide wheels with wire grooves formed in the outer ring, wherein the wire grooves of the wire guiding roller or the guide wheels are of an integrated structure or a relatively fixed structure with the wire guiding roller or the guide wheels, once the wire grooves are worn, the whole guide wheels or the wire guiding roller are required to be replaced, great waste can be caused, work hours can be wasted due to replacement, and the production efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a but buddha's warrior attendant line-cutting substitution wire device, the effectual change loss that reduces wire device.

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

the utility model provides a but diamond wire cutting substitution wire device, includes the rim plate, the rim plate outer lane is provided with the wire casing layer, the wire casing layer is detachable construction for the rim plate.

The wire groove layer can be replaced at any time after being worn, and the whole wire device does not need to be replaced.

Further, the wheel disc is sleeved outside the shaft sleeve of the guide wheel structure or the wire guide roller structure.

The above-described structure can be applied to a single guide roller as well as to a wire guide roller.

Further, the wire groove layer is a polyethylene layer.

The high-density polyethylene has high rigidity, hardness and strength, good wear resistance and high cost performance.

Further, the wire casing layer gomphosis is between the chimb and the clamping ring of rim plate, the clamping ring sets up in the side of rim plate.

When the wire groove layer is installed, the wire groove layer is sleeved on the outer ring edge of the wheel disc, and then the wire groove layer is fixed through the pressing ring, so that the wire groove layer cannot fall off from the wheel disc.

Further, in the guide wheel structure, the wheel disc is fixed with the shaft sleeve, and a bearing is arranged between the shaft sleeve and the rotating shaft.

Furthermore, in the wire guide roller structure, a bearing is arranged between the wheel disc and the shaft sleeve, and the shaft sleeve is arranged on the rotating shaft.

The wheel disc rotates along with the movement direction of the diamond wire along with the pulling force of the diamond wire, so that the abrasion of the diamond wire to the wire groove can be reduced, and the wheel disc needs to have flexible rotation capacity relative to the rotating shaft.

Furthermore, a gland is covered at one end of the rotating shaft.

The gland is used for assisting in fixing the deep groove ball bearing and preventing foreign objects from entering to influence the operation of the deep groove ball bearing.

Furthermore, a plurality of wire grooves are formed in the wire groove layer.

When one wire groove in the wire groove layer is worn, the wire groove layer does not need to be replaced immediately, and the other wire groove layer can be replaced for use.

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

through simple dismantlement, can change outmost wire casing layer, very big reduction the grinding loss when buddha's warrior attendant wire-electrode cutting.

Detailed Description

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

As shown in figures 1 and 2, the replaceable wire device for diamond wire cutting adopts a guide wheel structure, and comprises a wheel disc 1, a polyethylene layer 2 (namely a wire groove layer) is sleeved on the outer ring side of the wheel disc 1, and a plurality of wire grooves are formed in the polyethylene layer 2. One side of the outer ring edge of the wheel disc 1 extends outwards to form a convex edge 11, the polyethylene layer 2 is limited by the convex edge 11 after being sleeved on the wheel disc 1, a corresponding pressing ring 3 is arranged on the other side of the outer ring edge, the polyethylene layer 2 can be limited on the outer ring edge of the wheel disc 1, the outer ring edge of the other side of the wheel disc 1 can be made into an arc-shaped angle, and the polyethylene layer 2 can be conveniently sleeved; and the compression ring 3 is fixed on the side surface of the wheel disc 1 through bolts.

The wheel disc 1 is sleeved on a rotating shaft 5 through a shaft sleeve 4, and a deep groove ball bearing 6 is arranged between the rotating shaft 5 and the shaft sleeve 4; the wheel disc 1 rotates along with the movement direction of the diamond wire along with the pulling force of the diamond wire, so that the abrasion of the diamond wire to the wire groove can be reduced, and the wheel disc 1 needs to have flexible rotation capacity relative to the rotating shaft 5. One end cover of pivot 5 is equipped with gland 7, and gland 7 is used for assisting fixed deep groove ball bearing 6 and prevents that there is the foreign object to enter the operation that influences deep groove ball bearing 6.

During the change, loosen a plurality of bolts on the clamping ring 3 earlier, take off behind the clamping ring 3, take off polyethylene layer 2 from the clamping ring 3 side again, after the polyethylene layer 2 of renewal, adorn clamping ring 3, screw up the bolt can, need not to change whole guide pulley.

As shown in fig. 3, when the wire guide roller structure is adopted, the outer ring side of the wheel disc 1 is provided with a polyethylene layer 2 (namely a wire groove layer), the convex side structure and the compression ring structure of the wheel disc are consistent with the scheme, the difference lies in that a plurality of shaft sleeves 4 are arranged on the rotating shaft 5, the wheel disc 1 is sleeved outside the shaft sleeves 4, and the bearing is arranged between the wheel disc 1 and the shaft sleeves 4.

The aforesaid is only the embodiment of the utility model discloses, all simultaneously the utility model discloses in related words such as "upper and lower, left and right, centre" only do the reference usefulness, not absolutely restricted, all utilize the utility model discloses carry out insubstantial change, all shall belong to the act of infringing the protection scope of the utility model.
