Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire cutting, in particular to a wire roller, a wire-retracting and -releasing device and a wire cutting machine. Background Art
[0002] Multi-wire cutting is a cutting method in which the cutting wire reciprocates at high speed and moves relative to the workpiece to be cut (such as high-hardness and brittle materials) so that the cutting wire cuts the workpiece to be cut into hundreds of thin slices at a time.
[0003] In order to improve the cutting efficiency, the multi-wire cutting machine is required to have a large winding volume and a high line speed. However, the current wire roller can only correspond to a certain winding volume. If the winding volume and line speed are directly increased on the basis of the current wire roller, the overall weight of the wire roller will increase. At this time, the wire roller body will be easily deformed due to the insufficient rigidity and strength of the wire roller itself. If the wire roller of the corresponding specification is redesigned, the original wire roller can only be scrapped, which is not conducive to cost saving.
[0004] In response to the above problems, some manufacturers have proposed adding reinforcements inside the wire roller to support the wire roller in order to improve the strength and rigidity of the wire roller. At present, the reinforcements are made of steel, which to some extent solves the problem of low rigidity and strength of the wire roller. However, in actual application, the applicant found that the improved wire roller is not conducive to controlling the overall weight and moment of inertia, resulting in a decrease in cutting efficiency.
[0005] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content
[0006] In order to solve at least one of the above-mentioned problems in the prior art, that is, to solve the problem of reduced cutting efficiency after adding reinforcements to the existing wire roller, the first aspect of the present application provides a wire roller, which includes: a wire roller body, the wire roller body is provided with a through hole along the axial direction; a reinforcement, the reinforcement is embedded in the through hole along the axial direction of the wire roller body to support the wire roller body; wherein the reinforcement is made of ceramic or ceramic composite material.
[0007] By setting a reinforcement made of ceramic or ceramic composite materials inside the wire roller body, the reinforcement can support the wire roller body, enhance the strength and rigidity of the wire roller body, thereby increasing the winding amount of the wire roller, and at the same time suppress the deformation of the wire roller body when the winding amount is large. In addition, when the wire roller body is detected to be damaged or deformed, only the outer layer of the wire roller body can be scrapped, and the internal reinforcement can be reused. Compared with reinforcements made of metal materials, reinforcements made of ceramic or ceramic composite materials have many advantages such as low density, large elastic modulus, and strong compressive resistance, which is conducive to reducing the overall weight of the wire roller, increasing the winding amount of the wire roller, and improving cutting efficiency.
[0008] In the preferred technical solution of the wire roller, the ceramic composite material is oxide ceramic, carbide ceramic or nitride ceramic.
[0009] In the preferred technical solution of the above wire roller, the ceramic composite material is alumina ceramic.
[0010] By using alumina ceramics as the material for preparing the reinforcement, the advantages of small increase in wire roller weight and good economy can be achieved while improving the strength of the wire roller.
[0011] In the preferred technical solution of the above wire roller, the alumina content in the alumina ceramic is above 70%.
[0012] By using alumina ceramics with an alumina content of more than 70%, the mechanical properties of the reinforcement can be maximized.
[0013] In a preferred technical solution of the above wire roller, the interior of the reinforcement is hollow.
[0014] By setting the interior of the reinforcement to be hollow, it is not only easier to install, but also the weight of the reinforcement can be reduced, further improving the economy.
[0015] In the preferred technical solution of the above-mentioned wire roller, the reinforcement member is a spacer sleeve.
[0016] By arranging the reinforcement member as a spacer, better integral stability can be provided for the line roller body, and at the same time, the rotational inertia of the line roller during operation is also smaller.
[0017] In the preferred technical solution of the above-mentioned wire roller, the wire roller further comprises a support sleeve, and the support sleeve is arranged in the spacer sleeve.
[0018] By providing the support sleeve, it can play a positioning role when installing the spacer, simplify the installation strength and reduce the difficulty of installation.
[0019] In the preferred technical solution of the above-mentioned wire roller, the support sleeve and the spacer sleeve are clearance-matched.
[0020] Through the clearance fit between the support sleeve and the spacer sleeve, it is possible to avoid excessive force inside the spacer sleeve and affect the mechanical properties of the spacer sleeve.
[0021] In the preferred technical solution of the above-mentioned wire roller, the support sleeve is provided with a radial countersunk hole or a through hole.
[0022] By providing a radial countersunk hole or a through hole, a connecting piece can be provided in the radial countersunk hole or the through hole to fix the support sleeve, thereby improving the connection stability of the support sleeve.
[0023] In the preferred technical solution of the above-mentioned wire roller, there is an interference fit or a transition fit between the reinforcement member and the wire roller body.
[0024] The interference fit between the reinforcement and the main body of the wire roller is conducive to improving the stability of the wire roller. The transition fit between the reinforcement and the main body of the wire roller can maintain a small gap or a small interference fit between the two, which can reduce the difficulty of assembly and improve the matching effect between the reinforcement and the main body of the wire roller. At the same time, it is convenient to replace the main body of the wire roller and reuse the reinforcement, saving costs.
[0025] In a preferred technical solution of the above-mentioned wire roller, the length of the reinforcement member is smaller than the length of the through hole.
[0026] The above arrangement makes it easier for the reinforcement to avoid other structures.
[0027] In the preferred technical solution of the above-mentioned wire roller, the wire roller body is made of aluminum alloy or carbon structural steel.
[0028] The use of aluminum alloy to prepare the wire roller body is conducive to the lightness of the wire roller body. When the wire roller body is prepared using carbon structural steel, the material cost is low and the strength is high.
[0029] In the preferred technical solution of the above-mentioned wire roller, two ends of the wire roller body respectively extend radially outward to form a first flange and a second flange.
[0030] By providing the first flange and the second flange, the wire on the wire roller body can be limited to prevent the wire from slipping off.
[0031] In a second aspect of the present application, a wire-retracting and -paying device is provided, which comprises a wire roller according to any one of the above-mentioned technical solutions.
[0032] By using the above-mentioned wire roller in the wire-reeling device, the strength and rigidity of the wire roller can be improved, thereby increasing the winding amount of the wire-reeling device and suppressing the deformation of the wire roller body when the winding amount is large. In addition, when the roller body is detected to be damaged or deformed, only the outer layer of the wire roller body can be scrapped, and the internal reinforcement can be reused. Compared with reinforcements made of metal materials, reinforcements made of ceramic or ceramic composite materials have many advantages such as low density, large elastic modulus, and strong compressive resistance, which is beneficial to reduce the overall weight of the wire roller, increase the winding amount of the wire roller, and improve cutting efficiency.
[0033] In the preferred technical solution of the above-mentioned wire-retracting and -releasing device, the wire-retracting and -releasing device further comprises: a first clamping member, which is arranged at one end of the wire roller body, and a second clamping member, which is arranged at the other end of the wire roller body.

[0043] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. For example, although the reinforcement members in the accompanying drawings are described in conjunction with the spacer sleeve, the form of the reinforcement members is not fixed, and those skilled in the art can adjust them as needed to adapt to specific applications.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0045] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0046] First refer to Figure 1 and Figure 2 , the wire roller of the present application is described. Among them, Figure 1 This is a structural diagram of the wire roller of the present application; Figure 2 This is a cross-sectional view of the wire roller of the present application.
[0047] like Figure 1 As shown, in order to solve the problem of small winding volume of the existing wire roller, the wire roller 1 of the present application includes a wire roller body 11 and a reinforcement 12. The wire roller body 11 is provided with a through hole 113 along the axial direction, and the reinforcement 12 is embedded in the through hole 113 along the axial direction of the wire roller body 11 to support the wire roller body 11. Among them, the reinforcement 12 is made of ceramic or ceramic composite material.
[0048] In the assembled state, a large number of cutting wires are wound on the wire roller body 11, and the reinforcement 12 is embedded in the wire roller body 11 to support the wire roller body 11 from the inside out. Under the support of the reinforcement 12, the compression resistance of the wire roller body 11 is improved, so that more cutting wires can be wound. Among them, the reinforcement 12 made of ceramic or ceramic composite materials will increase the excellent properties such as high temperature resistance, high strength and stiffness, low density, and corrosion resistance, thereby making it possible to increase the strength and stiffness of the wire roller 1.
[0049] By arranging a reinforcement 12 made of ceramic or ceramic composite materials inside the wire roller body 11, the reinforcement 12 can support the wire roller body 11, enhance the strength and rigidity of the wire roller body 11, thereby increasing the winding amount of the wire roller 1, and at the same time suppressing the deformation of the wire roller body 11 when the winding amount is large. In addition, the above-mentioned arrangement makes it possible to scrap only the outer layer of the wire roller body 11 when external damage or deformation is detected on the wire roller body 11, and the internal reinforcement 12 can be reused, thereby reducing the replacement cost of the wire roller 1. Compared with reinforcements made of metal materials, the reinforcement 12 made of ceramic or ceramic composite materials has many advantages such as low density, large elastic modulus, and strong compressive resistance, which is beneficial to reducing the overall weight of the wire roller 1, increasing the winding amount of the wire roller 1, and improving cutting efficiency.
[0050] Refer to the following Figures 1 to 3, a preferred implementation of the present application is introduced. Among them, Figure 3 This is a cross-sectional view of the wire-reeling and -releasing device of the present application.
[0051] See also Figures 1 to 3 In a preferred embodiment, the wire roller 1 includes a wire roller body 11, a reinforcement member 12 and a support sleeve 13. The wire roller body 11 is in the shape of a cylinder with openings at both ends, and a through hole 113 is formed in the cylindrical wire roller body 11, and the inner walls at both ends of the through hole 113 are provided with chamfers. The axial ends of the wire roller body 11 extend radially outward to form a first flange 111 and a second flange 112, respectively, so as to form a winding area between the first flange 111 and the second flange 112. In the present application, the wire roller body 11 is made of carbon structural steel. Preferably, the carbon structural steel is 45 steel after quenching and tempering treatment.
[0052] In the above embodiment, when the wire roller body 11 is prepared by using carbon structural steel, the material cost is low and the prepared wire roller 1 has high strength. By providing the first flange 111 and the second flange 112, the winding on the wire roller body 11 can be limited to prevent the wire from slipping.
[0053] Of course, the specific setting method of the wire roller 1 is not unique, and those skilled in the art can adjust its structure so that the adjusted wire roller body 11 is suitable for more specific application scenarios. For example, the material of the wire roller body 11 is not unique, and other steel materials can be used in addition to 45 steel; of course, in addition to steel, other metal materials can also be used, such as aluminum alloy, etc. The use of aluminum alloy to prepare the wire roller body 11 is conducive to the lightweight of the wire roller body 11. For another example, flanges may not be set at both axial ends of the wire roller body 11, or a flange may be set at one end.
[0054] See also Figure 1 and Figure 2 , the interior of the reinforcement 12 is hollow. Specifically, the reinforcement 12 is a spacer, which is cylindrical as a whole, and the total length of the spacer is close to but less than the length of the through hole 113. In the present application, the material of the spacer is oxide ceramic, specifically, alumina ceramic. Preferably, the alumina content in the alumina ceramic is above 70%, and more preferably above 99%. During installation, a transition fit is adopted between the spacer and the wire roller body 11. For example, the spacer is embedded in the internal through hole 113 of the wire roller body 11 by heat assembly.
[0055] In the above-mentioned arrangement, the reinforcement 12 adopts a spacer sleeve with a length similar to that of the through hole 113, which can ensure the integrity of the reinforcement 12 and the support stability of the line roller 1. Through the transition fit between the spacer sleeve and the line roller body 11, a smaller gap or a smaller interference fit can be maintained between the two, which can reduce the difficulty of assembly and improve the matching effect between the reinforcement 12 and the line roller body 11. At the same time, it is convenient to replace the line roller body 11 and reuse the reinforcement 12, saving costs. By making the total length of the spacer sleeve shorter than the length of the through hole 113, it is convenient for the reinforcement 12 to avoid other structures. By using alumina ceramics as the material for preparing the reinforcement 12, the weight increase of the line roller 1 can be small and the economy is good while improving the strength and rigidity of the line roller 1. By using alumina ceramics with an alumina content of more than 70%, the mechanical properties of the reinforcement 12 can be improved. When the alumina content is more than 99%, the mechanical properties of the reinforcement 12 are optimal. Moreover, alumina ceramics are significantly superior to steel materials in terms of density, hardness, compressive strength, elastic modulus, thermal expansion coefficient, etc. In this way, adding a spacer inside the wire roller body 11 can make the wire roller 1 have a low density and a small overall weight gain while improving strength and rigidity. It will not add too much load to the currently used motor and reduce the work intensity and difficulty of the operator when installing and disassembling the wire roller 1. At the same time, the wire roller 1 has a small moment of inertia during operation, which is more conducive to the stability of winding and improves cutting efficiency.
[0056] Of course, the specific setting method of the wire roller 1 is not static, and those skilled in the art can adjust it according to the specific application scenario, as long as the adjusted technical solution meets the conditions for the reinforcement 12 to be prepared using ceramic composite materials. For example, in addition to alumina ceramics, ceramics can also be used. When using ceramic composite materials, the ceramic composite materials can also be other oxide ceramics, or carbide ceramics, nitride ceramics, etc., as long as the selected ceramic composite materials have good compressive properties and high elastic modulus (for example, the compressive properties and elastic modulus of the ceramic composite materials can be selected based on the material of the wire roller body 11). In addition, under the premise of using alumina ceramics, its alumina content can also be adjusted, such as using silicon nitride toughened alumina ceramics. For another example, although the reinforcement member 12 introduced above is described by taking the spacer as an example, the specific form of the reinforcement member 12 is not unique. The spacer is only a more preferred embodiment. In other embodiments, those skilled in the art may also replace the spacer with a solid columnar reinforcement block embedded in the through hole 113, multiple arc-shaped reinforcement blocks arranged in the through hole 113 to form a columnar / ring shape, multiple spacer rings arranged side by side along the axial direction of the through hole 113, etc. In addition, the length of the spacer may also be greater than the length of the through hole 113. For another example, although the above embodiment is described in conjunction with the transition fit between the line roller body 11 and the reinforcement member 12, the line roller body 11 and the reinforcement member 12 may also be an interference fit. When the interference fit connection method is used, it is beneficial to improve the stability of the line roller 1. Those skilled in the art may select the matching method of the two according to the specific application scenario.
[0057] Reference Figure 3 The support sleeve 13 is arranged in the spacer sleeve to support the installation of the line roller 1. Preferably, the support sleeve 13 and the spacer sleeve are clearance-fitted. The support sleeve 13 is formed with an axial hole, and the support sleeve 13 is also provided with a radial countersunk hole or a through hole (not shown in the figure) connected to the axial hole, so that the connecting member can pass through the countersunk hole or the through hole to fix the support sleeve 13, such as fixing it to the rotating shaft by bolts.
[0058] By providing the support sleeve 13, it can play a positioning role when installing the spacer, avoiding the misalignment of the line roller body 11 and the spacer during the installation process, simplifying the installation strength, and reducing the difficulty of installation. Through the clearance fit between the support sleeve 13 and the spacer, it can be avoided that the spacer is subjected to excessive force inside and affects the mechanical properties of the spacer. By providing radial countersunk holes or through holes, a connector can be provided in the radial countersunk holes or through holes to fix the support sleeve 13, thereby improving the connection stability of the support sleeve 13.
[0059] Of course, the arrangement of the support sleeve 13 is not unique, and those skilled in the art can adjust it. For example, the countersunk hole or the through hole can also be arranged at other positions along the radial direction of the support sleeve 13 or arranged at a certain angle with the radial direction, and those skilled in the art can choose to set it according to the needs of the specific application scenario. The support sleeve 13 can also be fixedly connected by a pin. Of course, the support sleeve 13 can also be not set.
[0060] Refer to the following Figure 3 , the wire-reeling and -releasing device of the present application is introduced.
[0061] like Figure 3 As shown, the present application also provides a wire-retracting and -paying device, which includes the wire roller 1 described in the above embodiment.
[0062] By using the above-mentioned wire roller 1 in the wire-reeling and unwinding device, the strength and rigidity of the wire roller 1 can be improved, thereby increasing the winding amount of the wire-reeling and unwinding device, and suppressing the deformation of the wire roller body 11 when the winding amount is large. In addition, when external damage or deformation is detected in the wire roller body 11, only the outer layer of the wire roller body 11 can be scrapped, and the internal reinforcement 12 can be reused. Compared with reinforcements made of metal materials, the reinforcement 12 made of ceramic or ceramic composite materials has many advantages such as low density, large elastic modulus, and strong compressive resistance, which is beneficial to reducing the overall mass of the wire roller, increasing the winding amount of the wire roller, and improving cutting efficiency.
[0063] See also Figure 3 In a specific embodiment, the wire retracting and releasing device includes a wire roller 1, a driving device 2, a main shaft 3, a first clamping member 4, a second clamping member 5 and a fastening assembly 6, and the wire roller 1 includes a wire roller body 11, a spacer sleeve and a support sleeve 13.
[0064] The driving device 2 is a motor, the output end of which is connected to the main shaft 3. The support sleeve 13 is sleeved on the main shaft 3. Bolts pass through the radially arranged through holes on the support sleeve 13 to lock the support sleeve 13 on the main shaft 3, so that there is no relative rotation between the support sleeve 13 and the main shaft 3. The spacer sleeve is sleeved in the through hole 113 of the line roller body 11, and the inner wall of the spacer sleeve is in clearance with the support sleeve 13. The first pressing member 4 is arranged at one end of the line roller body 11 ( Figure 3 The left end of the line roller body 11 is in contact with the right end of the first pressing member 4, and the left end of the first pressing member 4 is connected to the main shaft 3 through a connecting portion. The second pressing member 5 is provided at the other end of the line roller body 11 ( Figure 3The right end of the line roller body 11 is in contact with the left end of the second clamping member 5, and the fastening assembly 6 is arranged at the right end of the second clamping member 5, and clamps the second clamping member 5, thereby clamping and locking the second clamping member 5, the line roller 1 and the first clamping member 4 on the main shaft 3. At this time, the chamfers at both ends of the inner wall of the line roller body 11 are tightly combined with the right end of the first clamping member 4 and the left end of the second clamping member 5, respectively, and the spacer sleeve is not in contact with the first clamping member 4 and the second clamping member 5. A first flange 111 and a second flange 112 are formed on the line roller body 11, and the cutting line is wound between the two. Among them, the above-mentioned fastening assembly 6 is a conventional structure in the field and will not be repeated here.
[0065] By providing the first pressing member 4 and the second pressing member 5 , both ends of the wire roller body 11 can be pressed and fixed, thereby preventing the wire roller body 11 from moving during operation.
[0066] Of course, the above description of the wire-retracting and -unwinding device is only a possible setting method. Those skilled in the art may also adjust the specific structure of the wire-retracting and -unwinding device, or apply the wire roller 1 of the present application to other application scenarios, and such changes do not deviate from the principles of the present application. For example, in an alternative embodiment, at least one of the first clamping member 4 and the second clamping member 5 may be omitted, or other structures may be added between the first clamping member 4 / the second clamping member 5 and the wire roller body 11, so that the first clamping member 4 / the second clamping member 5 and the wire roller body 11 are indirectly clamped. For another example, the setting of the main shaft 3 may be omitted, and the motor output shaft may be transmission-connected to the first clamping member 4, and then the first clamping member 4 may be transmission-connected to the wire roller 1 directly or indirectly.
[0067] Finally, the present application also provides a wire cutting machine, which includes the wire roller 1 described in the above embodiment, or the wire retracting and releasing device in the above embodiment.
[0068] By using the wire roller 1 or the wire-retracting and -releasing device in the wire cutting machine, the strength and rigidity of the wire roller 1 can be improved, thereby increasing the winding amount of the wire roller 1 and suppressing the deformation of the wire roller body when the winding amount is large. At the same time, compared with the reinforcement of metal materials, the moment of inertia of the wire roller 1 is smaller during operation, which is more conducive to the stability of winding and the improvement of cutting efficiency.
