Description

[Technical Field]

[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a conical sleeve type carbon fiber roller. [Background Technology]

[0002] Wire cutting machines are popular due to their advantages such as small cutting kerf, and are now widely used in the processing of stone and other materials. For example, Chinese invention patent application number CN202410467280.0 discloses a multi-line pressing stone cutting machine.

[0003] The roller is an essential component of a wire EDM machine. One end is connected to a drive assembly, which rotates the roller during operation, driving the cutting wire. Because the cutting wire can damage the roller components during use, it is necessary to disassemble the roller for component replacement after a period of use. However, existing rollers typically require disassembly along with the drive assembly, and the roller's main shaft is usually made of metal, making disassembly inconvenient, the overall machine bulky, and energy-intensive. In view of these problems, the inventors of this invention conducted in-depth research, resulting in this invention. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a conical sleeve type carbon fiber roller, which solves the problems of existing rollers being not only inconvenient to disassemble, but also bulky and energy-intensive.

[0005] This utility model is implemented as follows: a conical sleeve type carbon fiber roller includes a carbon fiber tube body, a bearing seat, a conical sleeve, and a working layer; both ends of the carbon fiber tube body are provided with bearing seats, which are connected to the carbon fiber tube body by a fixing structure, and the two bearing seats are provided with shaft holes through the axial direction; a conical sleeve is provided on the outer side of each bearing seat, and the conical sleeve is provided with a conical hole that gradually narrows from the outside to the inside through the axial direction, and the axis of the conical hole coincides with the axis of the shaft hole; the working layer covers the outside of the carbon fiber tube body.

[0006] Furthermore, the fixing structure includes epoxy adhesive and reinforcing pins. The inner wall of the carbon fiber tube is bonded to the outer wall of the bearing seat by epoxy adhesive, and the carbon fiber tube and the bearing seat are also connected by several reinforcing pins.

[0007] Furthermore, the bearing seat and the carbon fiber tube body are assembled with an interference fit.

[0008] Furthermore, a transition tube is provided between the shaft holes of the two shaft seats.

[0009] Furthermore, the outer middle part of the bearing seat is recessed inward with a limiting groove, one end of the tapered sleeve is inserted into the limiting groove, and the tapered sleeve is locked together with the bearing seat by a number of locking parts.

[0010] Furthermore, the outer end of the bearing seat is provided with a limiting protrusion ring around the circumference, and the end of the carbon fiber tube abuts against the limiting protrusion ring.

[0011] Furthermore, the carbon fiber tube is wound using a wet continuous winding process, and the wall thickness of the carbon fiber tube is consistent along its length.

[0012] Furthermore, the carbon fiber tube body is made of T700 grade carbon fiber or M40 grade carbon fiber.

[0013] Furthermore, the working layer is made of a wear-resistant material.

[0014] Furthermore, the bearing is made of aluminum alloy.

[0015] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved:

[0016] 1. Because the carbon fiber roller has a shaft hole through the bearing seat and a tapered hole through the tapered sleeve, the carbon fiber roller and the mandrel are detachable during use. This allows for easy disassembly and assembly of the carbon fiber roller without disassembling the drive assembly that drives the carbon fiber roller. This greatly facilitates practical use.

[0017] 2. Using carbon fiber tubes as the main body of the roller, carbon fiber has superior specific strength and specific modulus compared to metal materials, and has a lower density. Therefore, compared with existing roller rollers made of metal materials, the overall weight of the carbon fiber roller roller is lighter, which can significantly reduce the energy consumption of the carbon fiber roller roller during operation. The lighter weight also makes disassembly and assembly easier. At the same time, it has higher specific strength and specific modulus; it can ensure that the product is lighter while maintaining the same strength, and can achieve higher strength while maintaining the same weight. In addition, it also has good water resistance, rust prevention, temperature resistance and non-deformation properties, and good product stability.

[0018] 3. Epoxy adhesive is used to bond the inner wall of the carbon fiber tube to the outer wall of the bearing, and reinforcing pins are used to pin the carbon fiber tube to the bearing. In addition, the interference fit between the bearing and the carbon fiber tube can effectively improve the bonding strength between the carbon fiber tube and the bearing, ensuring that the bearing will not detach from the carbon fiber tube during use, thereby ensuring the stability of the product during use.

[0019] 4. By setting a transition tube between the shaft holes of the two shaft seats, the transition tube can be used to support the mandrel during the actual assembly process, which greatly facilitates the actual assembly operation. [Attached Image Description]

Detailed Implementation Methods

[0031] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing these embodiments and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0033] Please see Figure 1As shown, a preferred embodiment of the present invention is a conical sleeve type carbon fiber roller 100. The carbon fiber roller 100 includes a carbon fiber tube body 1, a bearing seat 2, a conical sleeve 3, and a working layer 4. The carbon fiber tube body 1 serves as the main body of the roller, the bearing seat 2 and the conical sleeve 3 are used to assemble a mandrel (not shown), and the working layer 4 is used to wind cutting lines, etc. Both ends of the carbon fiber tube body 1 are provided with bearing seats 2, which are connected to the carbon fiber tube body 1 by a fixing structure. The two bearing seats 2 are provided with shaft holes 21 through the axial direction so that the mandrel can pass through the two bearing seats 2 during assembly. A conical sleeve 3 is provided on the outer side of each bearing seat 2. The conical sleeve 3 is provided with a tapered hole 31 that gradually narrows from the outside to the inside through the axial direction, and the axis of the tapered hole 31 coincides with the axis of the shaft hole 21 to ensure the stability of the shaft after assembly. The working layer 4 covers the outside of the carbon fiber tube body 1.

[0034] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0035] 1. Because the carbon fiber roller 100 has a shaft hole 21 through the shaft seat 2 and a tapered hole 31 through the tapered sleeve 3, the carbon fiber roller 100 and the mandrel are detachably assembled during actual use. Therefore, the carbon fiber roller 100 can be easily disassembled and assembled separately without disassembling and assembling the drive assembly that drives the carbon fiber roller 100. This greatly facilitates actual use.

[0036] 2. The carbon fiber tube 1 is used as the main body of the roller. Because carbon fiber has a better specific strength and specific modulus than metal materials, and has a lower density, the overall weight of the carbon fiber roller 100 is lighter than that of existing roller rollers made of metal materials. This can significantly reduce the energy consumption of the carbon fiber roller 100 during operation. The lighter weight also makes disassembly and assembly easier. At the same time, it has higher specific strength and specific modulus. It can ensure that the product is lighter while maintaining the same strength, and can achieve higher strength while maintaining the same weight. In addition, it also has good water resistance, rust prevention, temperature resistance and non-deformation properties, and good product stability.

[0037] In a preferred embodiment of the present invention, the fixing structure includes an epoxy adhesive 51 and reinforcing pins 52. The inner wall of the carbon fiber tube 1 and the outer wall of the bearing seat 2 are bonded together by the epoxy adhesive 51, and the carbon fiber tube 1 and the bearing seat 2 are also connected by a number of reinforcing pins 52.

[0038] Furthermore, the bearing 2 and the carbon fiber tube 1 are assembled with an interference fit.

[0039] This invention uses epoxy adhesive 51 to bond the inner wall of the carbon fiber tube 1 to the outer wall of the bearing seat 2, and uses reinforcing pins 52 to pin the carbon fiber tube 1 and the bearing seat 2 together. In addition, the interference fit assembly between the bearing seat 2 and the carbon fiber tube 1 can effectively improve the bonding strength between the carbon fiber tube 1 and the bearing seat 2, ensuring that the bearing seat 2 will not detach from the carbon fiber tube 1 during use, thereby ensuring the stability of the product during use.

[0040] In a preferred embodiment of the present invention, a transition tube 6 is provided between the shaft holes 21 of the two bearing seats 2.

[0041] Since the overall length of the carbon fiber roller 100 is relatively long, and the mandrel needs to pass through the inside of the carbon fiber roller 100 during the assembly process, this brings certain difficulties to the actual assembly. To this end, this utility model sets a transition tube 6 between the shaft holes 21 of the two shaft seats 2, so that the transition tube 6 can support the mandrel during the specific assembly process, thereby greatly facilitating the actual assembly operation.

[0042] In a preferred embodiment of this utility model, a limiting groove 22 is recessed inward at the center of the outer side of the bearing seat 2. One end of the tapered sleeve 3 is inserted into the limiting groove 22, and the tapered sleeve 3 is locked together with the bearing seat 2 by a plurality of locking members 7, so that the tapered sleeve 3 can be reliably combined with the bearing seat 2. The locking members 7 can specifically be hexagon socket head cap screws.

[0043] In a preferred embodiment of the present invention, in order to facilitate the assembly of the bearing seat 2 and to limit its position, a limiting protrusion 23 is provided around the outer end of the bearing seat 2 in the circumferential direction, and the end of the carbon fiber tube 1 abuts against the limiting protrusion 23.

[0044] In a preferred embodiment of this utility model, the carbon fiber tube 1 is wound using a wet continuous winding molding process. The wet continuous winding molding process is a very mature process in the field of carbon fiber, so it will not be described in detail here. The wall thickness of the carbon fiber tube 1 is consistent along its length to ensure the structural stability of the carbon fiber tube 1. The inner wall of the carbon fiber tube 1 is a smooth inner wall.

[0045] In a preferred embodiment of this invention, the carbon fiber tube is made of T700 grade carbon fiber or M40 grade carbon fiber; specifically, it can be made of T700 grade high-performance carbon fiber reinforced high-temperature resistant epoxy resin composite material, whose density is much lower than that of steel (7.8 g / cm³). 3 And aluminum alloy 2.7g / cm 3Furthermore, the carbon fiber tube 1 is manufactured by using T700 grade high-performance carbon fiber reinforced high-temperature resistant epoxy resin composite material and wet continuous winding molding process. Because T700 grade carbon fiber has high mechanical properties and high-temperature resistant epoxy resin has excellent temperature resistance, it can ensure that the carbon fiber tube 1 has high strength, good thermal stability and good resistance to cutting fluid corrosion.

[0046] In a preferred embodiment of this invention, the working layer 4 is made of a wear-resistant material to ensure that it is not easily worn during use and to improve its service life. As a specific implementation of this invention, the working layer 4 can specifically be made of polyurethane rubber, and the polyurethane rubber is tightly bonded to the outer wall of the carbon fiber tube 1 through a rubber vulcanization process. This ensures that the polyurethane rubber and the outer wall of the carbon fiber tube 1 are reliably bonded together, thereby guaranteeing the stability of the product during use. Simultaneously, polyurethane rubber has good wear resistance and a longer service life. Of course, the above-mentioned polyurethane rubber is only one specific embodiment of this invention, but the invention is not limited to this; other wear-resistant materials can be used according to actual needs in specific implementations.

[0047] In a preferred embodiment of this utility model, the bearing seat 2 is made of aluminum alloy, specifically 7075 (T6) aluminum alloy. Because aluminum alloy is relatively light, it is beneficial to further reduce the weight of the entire carbon fiber roller 100. In addition, aluminum alloy has high strength and excellent machinability. Through the cooperation between the aluminum alloy bearing seat and the carbon fiber tube 1, the overall strength can be guaranteed.

[0048] In the specific assembly of the carbon fiber roller 100 of this utility model, the mandrel passing through the carbon fiber roller 100 can be a screw, and both ends of the tapered sleeve 3 of the carbon fiber roller 100 are equipped with a cone head (not shown). Each cone head is rotatably mounted on a support seat (not shown). One end of the screw is connected to one of the cone heads, and the drive assembly is connected to the cone head. At the same time, the other end of the screw passes through the other cone head and is equipped with a locking nut (not shown) for locking. In this way, only the support seat with the locking nut at one end needs to be designed to be detachable, so that the carbon fiber roller 100 can be easily disassembled during use without disassembling the drive assembly.

[0049] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
