Description

Technical Field

[0001] This utility model relates to the technical field of stone processing equipment, specifically a roller for a high wear-resistant and deformation-resistant multi-wire stone cutting machine. Background Technology

[0002] In the stone processing industry, multi-wire cutting machines have become one of the core equipment for stone cutting due to their high efficiency and precision cutting performance. As a key component of multi-wire cutting machines, the roller device plays an important role in supporting and driving the cutting wire. Its performance directly affects the quality and efficiency of stone cutting. With the continuous improvement of the stone processing industry's requirements for product quality and production efficiency, more stringent standards have been put forward for the wear resistance and deformation resistance of the roller device.

[0003] However, existing roller devices for multi-wire stone cutting machines still have some problems during use:

[0004] First, traditional rollers are mostly made of ordinary carbon steel or single aluminum alloy, which have insufficient wear resistance. During cutting, friction with diamond wire causes severe surface wear, which in turn reduces the service life of the roller device.

[0005] Secondly, the traditional roller mounting surface does not have a specific taper design, which makes the roller prone to axial movement during use;

[0006] In addition, the existing rollers are not strong enough and have poor heat dissipation, which will also affect the service life of the roller structure. Utility Model Content

[0007] To address the problems of insufficient wear resistance and lack of specific taper design in existing roller devices, which lead to axial movement and insufficient strength and heat dissipation during use, the purpose of this utility model is to provide a roller for a multi-wire stone cutting machine with high wear resistance and deformation resistance.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high wear-resistant and deformation-resistant stone multi-wire cutting machine roller, comprising a roller body, tapered fitting components symmetrically and movably provided on both sides of the roller body, a wear-resistant component provided on the outer surface of the roller body, the wear-resistant component comprising a stainless steel sleeve, the stainless steel sleeve being fixedly fitted onto the outer surface of the roller body, and the outer surface of the stainless steel sleeve being knurled.

[0009] Preferably, the tapered fitting assembly includes a tapered body, which is movably inserted into the end of the roller body. A tapered fitting surface is symmetrically provided on one side of the tapered body. A first mounting threaded hole is provided in an annular array on one side of the tapered body, and a second mounting threaded hole is provided in an annular array on one side of the roller body for use with the first mounting threaded hole. The corresponding first mounting threaded hole and second mounting threaded hole are connected by bolts.

[0010] Preferably, reinforcing support plates are fixedly installed at equal intervals inside the roller body, and a ventilation opening is provided on one side of the reinforcing support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This application utilizes wear-resistant components, with the roller body adopting a composite structure of stainless iron and aluminum alloy, which effectively improves the wear resistance of the roller structure. At the same time, the knurling on the outer working area surface increases the coefficient of friction with the diamond wire, reduces slippage, and significantly increases the service life of the roller structure.

[0013] 2. This application uses a tapered fitting assembly, in which tapered mating surfaces are set at both ends of the roller to interfere with the tapered hole of the cutting machine spindle and are coated with glue. Compared with the traditional planar fit, this effectively solves the problem of axial movement of the roller during use.

[0014] 3. By setting up a reinforced support plate and ventilation openings, this application effectively improves the strength and heat dissipation of the roller, and further extends the service life of the roller structure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-4 As shown, this utility model provides a highly wear-resistant and deformation-resistant roller for a multi-wire stone cutting machine, including a roller body 1. The roller body 1 is made of composite aluminum alloy, which improves the wear resistance of the roller body 1. The roller body 1 has symmetrically movable tapered fitting components 3 on both sides, which improves the positioning accuracy by 70% compared with the traditional planar fitting, and eliminates the need for additional positioning keys, reducing the installation time to 15 minutes. This effectively solves the problem of axial movement of the roller during use. The outer surface of the roller body 1 is provided with a wear-resistant component 2, which includes a stainless steel sleeve 21. The stainless steel sleeve 21 is fixedly fitted onto the outer surface of the roller body 1. As a component of the outer working area of ​​the roller body 1, the stainless steel sleeve 21, after surface quenching treatment, has a quenching layer with a thickness of 0.5 mm, which can ensure that the surface wear is ≤0.1 mm after 500 hours of continuous cutting, and the service life is twice that of traditional rollers. The outer surface of the stainless steel sleeve 21 is provided with knurling 22. At the same time, the setting of the knurling 22 specification 2100.0±0.05 increases the friction coefficient between the roller and the diamond wire to 0.8, while the friction coefficient of the traditional smooth surface is 0.4, which effectively reduces slippage and improves cutting stability.

[0023] The tapered fitting assembly 3 includes a tapered body 36, which is movably inserted into the end of the roller body 1. The inner wall of the roller body 1 and the outer surface of the tapered body 36 are matched in shape. Through a precise fit of a 7:24 tapered surface with a length of 52.0 mm, IT6 level positioning accuracy is achieved. The interference fit of 0.01-0.03 mm and the structural adhesive filling ensure a clamping force of 1500 N. Compared with the traditional planar fit, the axial movement is reduced by 70%, from 0.1 mm to ≤0.03 mm. The outer surface of the tapered body 36 is symmetrically provided with first positioning pin holes 32, and the outer surface of the roller body 1 is symmetrically provided with second positioning pin holes 31 that are used to mate with the first positioning pin holes 32. The corresponding first positioning pin holes 32 and second positioning pin holes 31 are connected by positioning pins, effectively preventing angular deviation caused by torque during cutting, reducing the wire saw offset from 0.2 mm. The taper body 36 has a tapered mating surface 33 symmetrically formed on one side. The 7:24 standard taper design conforms to ISO 296 standards and forms a clearance-free fit with the tapered hole of the cutting machine spindle. The axial positioning accuracy reaches ±0.01mm. No additional keyway structure is required, simplifying the installation process and avoiding stress concentration problems caused by traditional key connections, thus extending the service life of the spindle. The tapered body 36 has a first mounting threaded hole 35 arranged in a ring array on one side, and the roller body 1 has a second mounting threaded hole 37 arranged in a ring array on one side to mate with the first mounting threaded hole 35. The corresponding first mounting threaded hole 35 and second mounting threaded hole 37 are connected by bolts. The first mounting threaded hole 35 and second mounting threaded hole 37 have a depth of 24.0mm and are fitted with 8.8 grade high-strength bolts with a torque of [missing value]. It provides 500N axial preload, and combined with the self-locking effect of the tapered surface, it effectively resists the peak axial impact force of up to 300N during the cutting process, ensuring that the axial displacement is ≤0.02mm after 8 hours of continuous cutting.

[0024] The roller body 1 is internally fixed with reinforcing support plates 4 at equal intervals. The reinforcement support plates 4 optimize the structural strength of the roller body 1. The roller body 1 has a wall thickness of 18.0 mm. 3 mm reinforcing ribs are added around the threaded holes in the stress concentration area using the reinforcement support plates 4. Finite element analysis shows that the maximum stress is reduced by 28%, and the fracture strength is increased to 300 MPa. The reinforcement support plates 4 are made of aluminum alloy, and the thermal conductivity of the 7075 aluminum alloy reinforcement support plates 4 reaches 130 W / (m²). The strength is three times that of stainless steel. The reinforcing support plate 4 has a ventilation port 5 on one side. With the ventilation port 5, heat can be quickly discharged through the substrate. Combined with external air cooling, the surface temperature of the roller is stabilized at 42±3℃, and the thermal deformation is ≤0.02mm. This ensures both strength and efficient heat dissipation, meeting the requirements of high-precision cutting.

[0025] Working principle: First, apply high-strength structural adhesive with a viscosity of 5000cP to the 7:24 taper mating surface 33 of the taper body 36. Then, align it with the taper hole of the cutting machine spindle and press it in slowly. Utilizing an interference fit of 0.01-0.03mm, a clamping force of 1500N is generated to ensure the precise positioning of the roller in the axial direction. Compared with the traditional planar fit, the axial movement is significantly reduced from 0.1mm to ≤0.03mm.

[0026] First, fix the circumferential position by passing the locating pin through the first locating pin hole 32 and the second locating pin hole 31. Then, connect the first mounting threaded hole 35 and the second mounting threaded hole 37 with an M12-6H bolt and apply... The torque provides 500N of axial preload, further enhancing connection stability.

[0027] When the equipment enters the cutting operation stage, the various components of the roller device work together. Through the wear-resistant component 2, the stainless steel shell 21 on the outer periphery of the roller body 1 is surface hardened to HRC42-45, which improves the wear resistance of abrasive particles by 60%. The knurled structure 22 on its outer surface increases the coefficient of friction with the diamond wire to 0.8, compared to 0.4 for traditional smooth surfaces. This effectively drives the diamond wire to run stably at a speed of 20m / s, while reducing abnormal wear caused by slippage.

[0028] The roller body 1 has aluminum alloy reinforcing support plates 4 arranged at equal intervals inside. In the stress concentration area, 3mm reinforcing ribs are added. Finite element analysis has verified that this reduces the maximum stress of the roller by 28% and increases the fracture strength to 300MPa, ensuring that the roller does not deform when subjected to a 200mm deep cutting load and maintains a stable cutting trajectory.

[0029] Meanwhile, the thermal conductivity of the aluminum alloy reinforced support plate 4 reaches 130W / ( Combined with the ventilation port 5, it forms an efficient heat dissipation channel. With the help of the external air cooling system, the surface temperature of the roller is stably controlled at 43℃, and the thermal deformation is ≤0.02mm. This avoids the degradation of material properties and damage to components caused by high temperature, and meets the high-precision cutting requirements of stone.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
