Description

Technical field

[0001] The present invention relates to the technical field of cutting machines, and in particular to a carbon fiber rubber-coated roller and a wire cutting machine. [Background Technology]

[0002] A wire-cutting machine primarily consists of a frame and a cutting assembly. The cutting assembly includes a support frame, several rollers rotatably mounted on the support frame, and two pay-and-take systems. The cutting wire is drawn from the first pay-and-take system and wound back and forth around the rollers to form a cutting mesh. The end of the cutting wire is connected to the second pay-and-take system. Driven by a rotary drive motor, the rollers can rotate forward and backward. During this rotation, the rollers drive the cutting mesh to saw back and forth, cutting the material. During the cutting process, the first pay-and-take system continuously releases new cutting wire, while the second pay-and-take system continuously retracts worn wire. However, the main shafts of existing rollers are typically made of metal, which presents drawbacks such as overall bulk, high energy consumption during operation, high moment of inertia, and poor specific strength and modulus. In light of these issues, the inventors conducted in-depth research, which led to the present invention. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to provide a carbon fiber coated roller and a wire cutting machine to solve the problem that the main shaft of the existing roller is usually made of metal material, which has the defects of being relatively heavy as a whole, high energy consumption during operation, large moment of inertia, poor specific strength and specific modulus, etc.

[0004] The present invention is achieved in that:

[0005] In a first aspect, a carbon fiber rubber-coated roller comprises:

[0006] Carbon fiber tube body;

[0007] Axle seats are provided at both ends of the carbon fiber tube body, and the axle seats are combined with the carbon fiber tube body through a fixing structure;

[0008] A shaft core, each of the shaft seats is connected to a shaft core, and one end of the shaft core extends to the outside of the carbon fiber tube body;

[0009] A working layer is coated on the outside of the carbon fiber tube body.

[0010] Furthermore, each of the shaft seats includes an inner shaft seat and an outer shaft seat arranged inside the carbon fiber tube body. The inner shaft seat and the outer shaft seat are interference fit with the carbon fiber tube body and are combined together through a fixed structure, and a buffer gap is left between the inner shaft seat and the outer shaft seat.

[0011] Furthermore, the inner shaft seat and the outer shaft seat are both provided with a first connecting flange with an axial hole, and two second connecting flanges are provided on the shaft core. The shaft core is inserted into the axial hole, and each first connecting flange is locked together with a second connecting flange through a plurality of first locking parts.

[0012] Furthermore, the fixing structure includes epoxy adhesive and reinforcing pins. The inner wall of the carbon fiber tube body and the outer wall of the shaft seat are bonded together by the epoxy adhesive, and the carbon fiber tube body and the shaft seat are also connected by a plurality of reinforcing pins.

[0013] Furthermore, the carbon fiber tube body is wound by a wet continuous winding process, and the wall thickness of the carbon fiber tube body is consistent along the length direction; the carbon fiber tube body is made of T700 grade carbon fiber or M40 grade carbon fiber.

[0014] Furthermore, the working layer is made of wear-resistant material.

[0015] Furthermore, the shaft core and the shaft seat are assembled by heat-fitting.

[0016] Furthermore, the shaft seat is made of aluminum alloy and the shaft core is made of 40Cr bar material.

[0017] Furthermore, it also includes a sealing plate. Both ends of the carbon fiber tube body are equipped with a sealing plate, and the sealing plate is locked and connected to the shaft seat through a plurality of second locking parts.

[0018] In a second aspect, a wire cutting machine is provided, wherein the wire cutting machine adopts the above-mentioned carbon fiber rubber-coated roller.

[0019] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0020] 1. A carbon fiber tube body is used as the roller body, a working layer is coated on the outside of the carbon fiber tube body, and an axle seat and an axle core are respectively set at both ends of the carbon fiber tube body to form a carbon fiber coated roller roller; because carbon fiber has better specific strength and specific modulus than metal materials, and has a lower density, compared with the existing roller roller made of metal materials, the overall weight of the entire carbon fiber coated roller roller is lighter, which can significantly reduce the energy consumption of the carbon fiber coated roller roller during operation, and has higher specific strength and specific modulus; under the condition of the same strength, it can ensure that the product is lighter, and under the condition of the same weight, it can make the product stronger; at the same time, it also has good water resistance, rust resistance, temperature resistance and not easy to deform, and the product stability is good.

[0021] 2. Each shaft seat is designed to include an inner shaft seat and an outer shaft seat, and the inner shaft seat and the outer shaft seat are interference fit with the carbon fiber tube body and combined together through a fixed structure, and a buffer gap is left between the inner shaft seat and the outer shaft seat; by adopting this double-shaft seat structural design, on the one hand, the bonding force between the carbon fiber tube body and the shaft seat can be improved, and the connection strength between the shaft seat and the carbon fiber tube body can be ensured; on the other hand, because there is a buffer gap between the inner shaft seat and the outer shaft seat, there is a certain hysteresis between the inner shaft seat and the outer shaft seat when the carbon fiber coated roller roller rotates forward and reverse, which is conducive to the mutual offset of torque, thereby reducing the moment of inertia and better adapting to the working conditions of emergency stop and start.

[0022] 3. The shaft seat is designed to include an inner shaft seat and an outer shaft seat. Both the inner shaft seat and the outer shaft seat are interference fit with the carbon fiber tube body, and the outer walls of the inner shaft seat and the outer shaft seat are bonded to the inner wall of the carbon fiber tube body through epoxy adhesive. At the same time, reinforcing pins are used to pin the inner shaft seat and the outer shaft seat to the carbon fiber tube body, which can effectively improve the bonding strength between the carbon fiber tube body and the shaft seat, ensuring that the shaft seat will not separate from the carbon fiber tube body during use, thereby ensuring the stability of the product during use.

[0023] 4. By using the thermal assembly method to assemble the shaft core and the shaft seat together, on the one hand, an interference fit can be achieved, and then combined with the locking of the first locking part, the shaft core and the shaft seat can be tightly combined together, thereby improving the assembly quality and ensuring the stability of use; on the other hand, it can improve the assembly efficiency and avoid damage to parts.

[0024] 5. By adopting the aluminum alloy shaft seat, on the one hand, because aluminum alloy is relatively light, it is beneficial to further reduce the weight of the entire carbon fiber coated roller. On the other hand, aluminum alloy has high strength and excellent machining performance. By matching the aluminum alloy shaft seat with the carbon fiber tube body, the overall strength can be guaranteed.

[0025] 6. By equipping both ends of the carbon fiber tube with sealing plates, it can be ensured that during the specific working process, external dust, water, etc. will not enter the interior of the carbon fiber tube body, which can protect the internal structure of the carbon fiber tube body and help to increase the service life of the carbon fiber coated roller.
