Description

Technical Field

[0001] This utility model relates to the field of felt cylinder processing technology, and in particular to a carbon-carbon composite felt cylinder rolling device. Background Technology

[0002] Carbon-carbon composite felt cylinders, as core components of high-performance thermal field equipment, are widely used in high-end manufacturing fields such as photovoltaic single-crystal pulling and semiconductor melting. Their quality directly determines the thermal insulation performance, structural stability, and service life of the thermal field. This component uses carbon fiber felt as a preform, processed through complex processes such as chemical vapor deposition and high-temperature graphitization. The forming quality of the preform, especially the uniformity, density, and interlayer bonding during the felt rolling process, is a prerequisite for ensuring the performance of the final product. Therefore, the technological level of felt cylinder rolling equipment plays a crucial supporting role in improving the overall manufacturing capabilities and product competitiveness of the downstream industry chain.

[0003] The existing felt rolling equipment is a manually assisted tooling. Its working mechanism involves manually controlling or motor-driven rollers to rotate, thereby completing the felt rolling process. During the rolling process, the felt roll is pressed by the upper pressure roller and the counterweights added on both sides. However, in this production process, the rolling speed is limited by the motor speed or interfered with by human operation. As the number of wrapping turns increases, it is difficult to effectively control the rolling speed. At the same time, since the equipment relies on the counterweights to press the felt roll, insufficient pressure and uneven pressure distribution are prone to occur during the pressing process. This results in large deviations in the thickness of the felt roll and insufficient interlayer bonding, leading to inconsistent product quality in each production run and affecting the product qualification rate.

[0004] Therefore, it is necessary to provide a carbon-carbon composite felt cylinder rolling device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a carbon-carbon composite felt cylinder rolling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a carbon-carbon composite felt cylinder rolling device, comprising a frame and an iron mold, wherein a main shaft drive mechanism, a pressing mechanism and an auxiliary pressure roller mechanism are provided on the frame; the main shaft drive mechanism includes a servo motor and a main shaft driven by the servo motor, the iron mold is mounted on the main shaft, and the pressing mechanism includes a pressure roller and a cylinder for driving the pressure roller to move up and down, the cylinder being fixed on the frame.

[0007] As a further embodiment of this utility model, the auxiliary pressure roller mechanism includes at least one auxiliary spring pressure roller, which is mounted on the frame via a spring bracket and located on one side of the iron mold.

[0008] As a further embodiment of this utility model, the iron mold is fixed to the main shaft by a top cone clamping mechanism. The top cone clamping mechanism includes a fixed top cone disposed at the front end of the main shaft, a movable top cone arranged opposite to the fixed top cone, and a hydraulic top cylinder. The movable top cone is driven to move and adjust along the main shaft axis by the hydraulic top cylinder.

[0009] As a further embodiment of this utility model, the servo motor is electrically connected to a host computer control system, which has a built-in control program for setting and controlling the rotation speed of the spindle so that the iron mold maintains a constant surface linear velocity.

[0010] As a further embodiment of this utility model, the spring bracket is provided with an adjusting bolt for pre-tightening and adjusting the initial pressure of the auxiliary spring pressure roller on the surface of the felt cylinder.

[0013] As a further embodiment of this utility model, emergency stop switches a and b, and a top cone control button for controlling the servo motor are provided at both ends of the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The rotation speed of the felt cylinder is precisely controlled by a servo motor, while the pressing force is ensured by a cylinder.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-5 This utility model provides a carbon-carbon composite felt rolling device, including a frame 1 and an iron mold 5. The frame 1 is equipped with a main shaft drive mechanism, a pressing mechanism, and an auxiliary pressure roller mechanism. The main shaft drive mechanism includes a servo motor 2 and a main shaft 4 driven by the servo motor 2. The iron mold 5 is mounted on the main shaft 4. The pressing mechanism includes a pressure roller 6 and a cylinder 7 that drives the pressure roller 6 to move up and down. The cylinder 7 is fixed on the frame 1. In use, the servo motor 2 drives the main shaft 4 and the iron mold 5 mounted on it to rotate at a uniform speed. The operator fixes the initial end of the carbon-carbon felt material on the rotating iron mold 5. The cylinder 7 pushes the pressure roller 6 to move and adjust, applying a constant and uniform pressure to the felt material. As the iron mold 5 rotates, the felt material is continuously wrapped around the surface of the iron mold 5 to form a felt cylinder. The servo motor 2 is used to precisely control the rotation speed of the felt cylinder, while the cylinder 7 ensures the pressing force. The pressure can be precisely controlled by adjusting the air pressure, which fundamentally solves the problems of uneven pressure and speed fluctuations in traditional processes, such as felt cylinder delamination and inconsistent thickness.

[0027] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the auxiliary pressure roller mechanism includes at least one auxiliary spring pressure roller 9. The auxiliary spring pressure roller 9 is mounted on the frame 1 via a spring bracket 10 and is located on one side of the iron mold 5. During this process, the auxiliary spring pressure roller 9 is always in contact with the surface of the felt material under the action of the spring, rolling and smoothing it. The introduction of the auxiliary spring pressure roller 9 further improves the tightness of the interlayer bonding and the surface flatness of the felt material, providing a more comprehensive guarantee for the automated production of high-quality carbon-carbon composite felt cylinders.

[0028] Further as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the iron mold 5 is fixed to the main shaft 4 by a top-cone clamping mechanism. The top-cone clamping mechanism includes a fixed top cone 11 located at the front end of the main shaft 4, a movable top cone 12 arranged opposite to the fixed top cone 11, and a hydraulic top cylinder 13. The hydraulic top cylinder 13 drives the movable top cone 12 to move and adjust along the main shaft axis. When clamping iron molds 5 of different sizes, the hydraulic top cylinder 13 is activated to push the movable top cone 12 towards the fixed top cone 11. The iron mold 5 is firmly locked on the main shaft 4 by the cooperation of the conical surfaces of the two top cones. When disassembling, the hydraulic top cylinder 13 retracts, driving the movable top cone 12 to move backward, thereby releasing the fixation of the iron mold 5. This realizes the rapid clamping and replacement of iron molds. Its adaptive characteristics allow clamping iron molds of different diameters, which greatly improves the production flexibility and operation efficiency of the equipment and solves the key clamping problem for the production of large-size felt cylinders.

[0029] Further as Figure 2 As shown, it is worth noting that the servo motor 2 is electrically connected to the host computer control system 16. The host computer control system 16 has a built-in control program used to set and control the rotation speed of the spindle 4, so that the iron mold 5 maintains a constant surface linear velocity. In actual operation, the host computer control system 16 sends instructions to the servo driver according to the preset process parameters to control the speed of the servo motor 2. The system is programmed to ensure that the spindle speed will be automatically adjusted no matter how the thickness of the felt roll on the iron mold increases, so as to ensure that the linear velocity of the contact point between the felt material and the pressure roller is constant. The constant linear velocity control ensures the extreme smoothness of the felt wrapping process, avoids sudden speed changes caused by changes in roll diameter, and thus prevents wrinkles or tears caused by uneven stress on the felt material, significantly improving the product forming quality and consistency.

[0030] This solution has the following working process: The servo motor 2 drives the main shaft 4 and the iron mold 5 mounted on it to rotate at a constant speed. The operator fixes the initial end of the carbon felt material on the rotating iron mold 5. The cylinder 7 pushes the pressure roller 6 to move and adjust, applying constant and uniform pressure to the felt material. As the iron mold 5 rotates, the felt material is continuously wrapped around the surface of the iron mold 5 to form a felt cylinder. During this process, the auxiliary spring pressure roller 9 always keeps in contact with the surface of the felt material under the action of the spring, rolling and smoothing it. When clamping iron molds 5 of different sizes, the hydraulic top cylinder 13 is activated to push the movable top cone 12 to move towards the fixed top cone 11. The iron mold 5 is firmly locked on the main shaft 4 through the cooperation of the conical surfaces of the two top cones. When disassembling, the hydraulic top cylinder 13 retracts, driving the movable top cone 12 to move backward, thereby releasing the fixation of the iron mold 5; thus realizing the quick clamping and replacement of the iron mold.

[0031] Further as Figure 1 As shown, it is worth noting that the spring bracket 10 is equipped with an adjusting bolt, which is used to pre-tighten and adjust the initial pressure of the auxiliary spring pressure roller 9 on the surface of the felt cylinder. In actual operation, the spring can be compressed or released by turning the adjusting bolt, thereby changing the pressing force of the auxiliary spring pressure roller 9 on the surface of the felt cylinder. The operator can flexibly adjust this pressure according to the requirements of different materials or process stages.

[0032] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a chip collection trough is provided at the bottom of the frame 1. During actual operation, the chip collection trough is located at the bottom of the equipment to collect the waste and debris generated during the production process, keeping the working environment clean and facilitating cleaning and maintenance.

[0033] Further as Figure 1 As shown, a guide rod 8 is installed at the bottom of the spring bracket 10, and an outer sleeve that engages with the guide rod 8 is fixed at the top of the frame 1.

[0034] Further as Figure 2 As shown, it is worth noting that emergency stop switches a14 and b15 for controlling servo motor 2 and top cone control button 3 are provided at both ends of the frame 1.

[0035] In summary: By precisely controlling the rotational speed of the felt roller using servo motor 2, ensuring the pressing force using cylinder 7, and accurately controlling the pressure using air pressure regulation, the problems of felt roller delamination and inconsistent thickness caused by uneven pressure and speed fluctuations in traditional processes are fundamentally solved. The auxiliary spring pressure roller 9 always adheres to the surface of the felt material under the action of the spring, rolling and smoothing it. The introduction of the auxiliary spring pressure roller 9 further improves the tightness of the interlayer bonding and the surface flatness of the felt material, providing a more comprehensive guarantee for the automated production of high-quality carbon-carbon composite felt rollers.

[0036] The servo motor 2, cylinder 7 and hydraulic top cylinder 13 can be purchased from the market. The servo motor 2, cylinder 7 and hydraulic top cylinder 13 are equipped with power supplies. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in the specification.
