Description

Technical Field

[0001] This application relates to the field of multi-wire cutting machines, and in particular to a cut-resistant multi-wire cutting machine master wheel. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. In related technologies, the guide wheel of a multi-wire cutting machine generally consists of two layers: an inner layer, a load-bearing structural layer made of materials such as steel, aluminum alloy, or carbon fiber, and an outer layer, a wear-resistant layer made of materials such as polyurethane or high-molecular-weight polyethylene. The wear-resistant layer has grooves for placing the working diamond wire. During operation, the working diamond wire is wound around the grooves of the guide wheel, and the friction provided by the main guide wheel drives the working diamond wire to move, thus enabling the working diamond wire to perform the cutting function.

[0003] However, during the operation of the working diamond wire wound on the guide wheel, due to factors such as the asynchronous operation of the various guide wheels, relative slippage occurs between the working diamond wire and the wear-resistant layer of the guide wheel, causing the working diamond wire to cut through the wear-resistant layer. Once the wear-resistant layer is cut through, it may cut into the structural layer of the guide wheel, causing damage to the structural layer or even severing the structural layer, ultimately resulting in the entire guide wheel being cut off, causing a major accident. Summary of the Invention

[0004] In view of this, this application provides a multi-wire cutting machine master wheel that prevents cutting and damage to the internal columns of the structure by the working diamond wire.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A cutting-resistant multi-wire cutting machine main drive wheel is characterized by comprising an inner column and a wear-resistant outer layer wrapped around the inner column. A cutting-resistant layer is fixedly provided between the inner column and the wear-resistant outer layer or in the wear-resistant outer layer. When the working diamond wire comes into contact with the cutting-resistant layer, the cutting-resistant layer cuts the working diamond wire.

[0007] The aforementioned multi-wire cutting machine master wheel of this application has an anti-cutting layer. When the working diamond wire collides with the anti-cutting layer, the working diamond wire will be cut first, and the machine will eventually stop due to wire breakage, preventing the master wheel from being further pulled deep, thereby protecting the internal columns of the structure from damage.

[0008] In some embodiments, the cut-resistant layer includes multiple sets of cutting units, wherein the cutting unit is at least one cut-resistant diamond wire or diamond cutter tip.

[0009] In some embodiments, the cut-resistant diamond wire or diamond cutting tip is fixed to the surface of the inner column of the structure in a straight line, and each group of cutting units is equally spaced in the circumferential direction of the inner column of the structure.

[0010] In some embodiments, the anti-cutting diamond wire or diamond blade is fixed on the surface of the structural inner column in a spiral arrangement.

[0011] From the above technical solution, the present application has at least the following advantages and positive effects:

[0012] The anti-cutting multi-wire cutting machine main guide wheel of the present application is provided with an anti-cutting layer. When the working diamond wire collides with the anti-cutting layer during operation, the working diamond wire will be cut off first, and the machine will eventually stop due to wire breakage, preventing the main guide wheel from being further deepened, thereby protecting the structural inner column from being damaged.

[0018] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0019] Embodiment one:

[0020] Referring to Figures 1 to 2 , the anti-cutting multi-wire cutting machine main guide wheel of the present embodiment comprises a structural inner column 1 and a wear-resistant outer layer 2 wrapped around the structural inner column 1. An anti-cutting layer 3 is fixedly arranged between the structural inner column 1 and the wear-resistant outer layer 2 or in the wear-resistant outer layer 2. The working diamond wire 4 in operation collides with the anti-cutting layer 3, and the anti-cutting layer 3 cuts off the working diamond wire 4.

[0021] The anti-cutting multi-wire cutting machine main guide wheel is provided with an anti-cutting layer 3. When the working diamond wire 4 in operation collides with the anti-cutting layer 3, the working diamond wire 4 will be cut off first, and the machine will eventually stop due to wire breakage, preventing the main guide wheel from being further deepened, thereby protecting the structural inner column 1 from being damaged.

[0022] The anti-cut layer 3 comprises a plurality of cutting units 31, preferably four cutting units 31, and the cutting unit 31 is at least one anti-cutting diamond wire 311, preferably three anti-cutting diamond wires 311.

[0023] The anti-cutting diamond wire 311 is fixed on the surface of the structural inner column 1 in a straight line distribution, the anti-cutting diamond wire 311 is parallel to the axis of the structural inner column 1, and each group of cutting units 31 is symmetrically arranged at equal intervals in the circumferential direction of the structural inner column 1.

[0024] The working diamond wire 4 and the anti-cutting diamond wire 311 are made of the same material.

[0025] The diamond wire is lighter in material relative to the cutter head, and after being attached to the outer layer of the guide wheel, the overall weight is lighter, which does not damage the original structure of the guide wheel and thus affect the strength, and also has less impact on the dynamic balance of the guide wheel.

[0026] The working process of the anti-cutting multi-wire cutting machine main guide wheel of the above embodiment is briefly described as follows:

[0027] The anti-cut layer 3 is formed by arranging a plurality of anti-cutting diamond wires 311 on the surface of the structural inner column 1, so that when the working diamond wire 4 is deepened in the groove during the working process, the working diamond wire 4 will first cut the anti-cut layer 3 before cutting the structural inner column 1, and the working diamond wire 4 will be cut by the anti-cut layer. When a single working diamond wire 4 is running at high speed, the working diamond wire 4 is more fragile, and the running diamond wire will be cut off first, so that the machine is stopped due to wire breakage, and the main guide wheel is prevented from being further deepened.

[0028] Embodiment two:

[0029] Referring to Figure 3 Another embodiment of the present application is shown, and the main improvement of this embodiment compared with the first embodiment is that the anti-cutting diamond wire 311 is replaced by a diamond cutter head 312.

[0030] Embodiment three:

[0031] Referring to Figure 4 Another embodiment of the present application is shown, and the main improvement of this embodiment compared with the first embodiment is that the anti-cutting diamond wire 311 is fixed on the surface of the structural inner column 1 in a spiral arrangement.

[0032] Compared with the first case, the spiral arrangement of the diamond wire is easier to fix when winding the diamond wire, and does not need to be symmetrically arranged for dynamic balance. At the same time, the diamond wire is directly wound tightly on the guide wheel shell by spiral winding, without the need to increase external force for fixation. However, the spiral arrangement of the diamond wire needs to arrange the anti-cutting diamond wire more uniformly, and the winding process is more complex. Moreover, in order to achieve a better anti-cutting effect, the winding needs to be more dense, which increases the difficulty of arrangement.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the foregoing embodiments of the present application have been described in detail, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments.
