DETAILED DESCRIPTION

[0026] The core of the present invention is to provide a carbon-carbon composite barrel demoulding mechanism, which drives multiple barrel sheets to expand and contract through a telescopic mechanism, so as to form a complete cylindrical outer wall, facilitate demoulding, and reduce loss.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Figure 6 Unlocking schematic diagram of a spring lock in a specific embodiment of the demoulding mechanism for a carbon-carbon composite material barrel provided by the present invention.

[0030] A specific embodiment of the present invention provides a demoulding mechanism for a carbon-carbon composite material barrel, which includes a frame, a driver, and a cylindrical mold. The driver is fixedly installed at one end of the frame, and the cylindrical mold is detachably installed at the other end of the frame. The cylindrical mold includes a horizontal rotating shaft 1 and a plurality of barrel pieces surrounding the rotating shaft 1. The end of the rotating shaft 1 is detachably connected to the driver, and the rotating shaft 1 is connected to each barrel piece through a telescopic mechanism. The telescopic mechanism can drive the plurality of barrel pieces to expand outwards so that the outer walls of the plurality of barrel pieces are spliced into a complete cylindrical outer wall, and the telescopic mechanism can also drive the plurality of barrel pieces to fold inwards so that the outer walls of the plurality of barrel pieces are separated from the carbon-carbon composite material barrel.

[0031] During the working process, a cylindrical mold of a suitable size is installed on the frame, and the driver is connected to the rotating shaft 1. At this time, the cylindrical mold is in an expanded state. The raw material is placed on the cylindrical mold, the driver is started to rotate the cylindrical mold to wrap the raw material, and resin is sprayed at the same time. After the wrapping is completed, the carbon-carbon composite material barrel is subjected to a drying process, and then the cylindrical mold is switched to a folded state, the cylindrical mold is removed for demoulding, and the carbon-carbon composite material barrel is separated.

[0032] By the above method, the shrinkage demoulding method is adopted, no draft angle is required, more raw materials are saved. When expanded, the outer walls of the barrel pieces are spliced into a complete cylindrical outer wall, which is convenient for cleaning, and resin will not flow into the gaps to cause jamming. Further, the violent pulling demoulding method is avoided, the workpiece is prevented from being damaged, the product quality is guaranteed, workpieces of different thicknesses are applicable, and the applicable range is improved.

[0033] Specifically, the telescopic mechanism includes a groove disk 2 and a plurality of support rods 3. The center of the groove disk 2 is fixedly connected to the rotating shaft 1 by a key. At the same time, a plurality of arc-shaped chutes 21 are arranged on the groove disk 2, and the plurality of arc-shaped chutes 21 are arranged around the center of the groove disk 2. The distance between the trajectory of the arc-shaped chute 21 from the end to the head and the center of the groove disk 2 gradually increases, that is, the trajectory of the arc-shaped chute 21 from the end to the head gradually moves away from the center of the groove disk 2. A pin 31 is arranged at the inner end of the support rod 3, and the pin 31 is embedded in the corresponding arc-shaped chute 21, so that the inner end of the support rod 3 is slidably connected to the corresponding arc-shaped chute 21. A boss is arranged at the outer end of the support rod 3, and the boss is fixedly embedded in the inner side surface of the cylinder piece, so that the outer end of the support rod 3 is fixedly connected to the inner side surface of the cylinder piece.

[0034] Further, in order to avoid interference between multiple cylinder pieces, a plurality of outer cylinder pieces 5 and a plurality of inner cylinder pieces 6 can be provided. Among them, the plurality of outer cylinder pieces 5 and the plurality of inner cylinder pieces 6 are arranged alternately. The outer side surface of the outer cylinder piece 5 is an arc surface, the inner side surface of the outer cylinder piece 5 is a plane, the outer side surface of the inner cylinder piece 6 is an arc surface, the inner side surface of the inner cylinder piece 6 is a plane, and inclined surfaces are arranged on both sides of the inner cylinder piece 6. The inner and outer edges of the inclined surfaces are respectively connected to the edges of the inner side surface and the outer side surface of the inner cylinder piece 6, so that the two inclined surfaces of the inner cylinder piece 6 are respectively attached to the inner side surfaces of two adjacent outer cylinder pieces 5. At the same time, the arc-shaped chute 21 connecting the inner cylinder piece 6 is closer to the center of the groove disk 2, and the arc-shaped chute 21 connecting the outer cylinder piece 5 is closer to the outer edge of the groove disk 2, so that the arc-shaped chute 21 connecting the inner cylinder piece 6 is located inside the arc-shaped chute 21 connecting the outer cylinder piece 5. Specifically, it includes three outer cylinder pieces 5 and three inner cylinder pieces 6, and three outer arc-shaped chutes 21 and three inner arc-shaped chutes 21 are correspondingly arranged, and six support rods 3 are provided. When the cylindrical mold is in the unfolded state, the outer wall forms a cylinder, and the inner wall forms a hexagonal prism. When the cylindrical mold is in the folded state, both the outer cylinder piece 5 and the inner cylinder piece 6 will contract inward, but the inner cylinder piece 6 contracts a greater distance, ensuring that the inner cylinder piece 6 contracts to the inside of the outer cylinder piece 5, and at the same time, two adjacent outer cylinder pieces 5 remain in contact with the inclined surfaces on both sides of the inner cylinder piece 6 and clamp the inner cylinder piece 6.

[0035] Among them, the outer diameter of the preset cylindrical mold is ф600mm, the outer diameter of the groove plate 2 is ф300mm. The diameter of the arc at the end of the inner arc-shaped chute 21 is ф50mm, and the diameter of the arc at the beginning is ф200mm. The diameter of the arc at the end of the outer arc-shaped chute 21 is ф210mm, and the diameter of the arc at the beginning is ф280mm. All parts are smoothly transitioned, so that when the inner end of the support rod 3 moves along the arc-shaped chute 21, it can drive the telescopic movement of the cylinder piece. That is, when the outer cylinder piece 5 contracts, the inner end of the corresponding support rod 3 moves from the position of ф280mm to the position of ф210mm, and the movement distance is 35mm. When the inner cylinder piece 6 contracts, the inner movement of the corresponding support rod 3 moves from the position of ф200mm to the position of ф50mm, and the movement distance is 37.5mm. That is to say, when the cylindrical mold with a complete outer circle changes its shape and contracts inward, the maximum movement distance of the inner cylinder piece 6 will be greater than that of the outer cylinder piece 5. As long as it is ensured that the movement speeds of the outer cylinder piece 5 and the inner cylinder piece 6 are uniform during the entire shape transformation process, the outer cylinder piece 5 and the inner cylinder piece 6 will not interfere during the contraction of the cylindrical mold, and the distance between them will become larger and larger.

[0036] Further, the center of the groove plate 2 is point O, the beginning of the outer arc-shaped chute 21 is point A, the end of the outer arc-shaped chute 21 is point B, the beginning of the inner arc-shaped chute 21 is point C, and the end of the inner arc-shaped chute 21 is point D. Then OA = 140mm, OB = 105mm, OC = 100mm, OD = 25mm. The included angle between OA and OB is 150°, and the included angle between OC and OD is 150°. If it is necessary to ensure that the movement speed of the outer cylinder piece 5 is uniform during the shape transformation of the cylindrical mold, the arc-shaped chute curve function of the outer cylinder piece 5 should enable the radius r of the pin 31 relative to the center O to decrease uniformly as the included angle θ between OA and OB decreases during the process of the pin 31 moving from point A to point B. The same applies to the inner cylinder piece 6. Figure 3 The vertical direction is the X-axis, and the horizontal direction is the Y-axis.

[0037] Calculation of the arc-shaped chute function of the outer cylinder piece 5:

[0038] Angle θ = α

[0039] Radius r = 140 - 35·α / 150°

[0040] X-axis coordinate x = (140 - 35·α / 150°)·sin(60° - α)

[0041] Y-axis coordinate y = (140 - 35·α / 150°)·cos(60° - α)

[0042] Calculation of the arc-shaped chute function of the inner cylinder piece 6:

[0043] Angle θ = α

[0044] Radius r = 100 - 75·α / 150°

[0045] The X-axis coordinate x = -(100 - 75·α / 150°)·sinα

[0046] The Y-axis coordinate y = (100 - 75·α / 150°)·cosα

[0047] The parameters and calculation methods of each structure can also be adjusted according to the situation, all within the protection scope of the present invention.

[0048] In the carbon-carbon composite material barrel demoulding mechanism provided by the specific embodiment of the present invention, two groove plates 2 are respectively arranged at both ends of the rotating shaft 1. A side plate 4 is arranged outside each groove plate 2. The inner side of the side plate 4 is detachably connected to the groove plate 2 through an inner positioning member, and the outer side of the side plate 4 is detachably connected to the machine frame through an outer positioning member. Specifically, both the inner positioning member and the outer positioning member include a spring lock 7 and a locking tongue 8. Blind holes are arranged at corresponding positions. When locking is required, the spring lock 7 is inserted into the blind hole. When unlocking is required, the spring lock 7 is pulled out of the blind hole, and at the same time, the locking tongue 8 catches the spring lock 7, making the spring lock 7 unable to be inserted into the blind hole.

[0049] Preferably, the driver is specifically a motor 9, and the output shaft of the motor 9 is connected to one end of the rotating shaft 1 through a coupling 10. Other types of drivers and connection methods can also be used, all within the protection scope of the present invention.

[0050] Based on the carbon-carbon composite material barrel demoulding mechanism provided by the above specific embodiments, the machine frame includes a tooling frame 12 and a driving frame 11 arranged in parallel. The rotating shaft 1 is installed above the tooling frame 12, and the driver is installed above the driving frame 11. Specifically, side frames are arranged at both ends of the tooling piece, the rotating shaft 1 is installed between the two side frames, an installation plate is arranged above the driving frame 11, and the driver is installed above the installation plate. Rollers can also be arranged below both the tooling frame 12 and the driving frame 11 to facilitate movement.

[0051] The specific working process is as follows:

[0052] Prepare raw material rolls (soft felt, carbon cloth, mesh tire, non-woven fabric, etc.) of appropriate sizes according to needs, select a cylindrical mold of appropriate size, and by default, the inner spring lock 7 is locked, and the groove plate 2 and the side plate 4 are locked. Place the cylindrical mold on the tooling frame 12.

[0053] Connect the motor 9 to the rotating shaft 1 through the coupling 10, and connect the tooling frame 12 to the driving frame 11, so that the power of the motor 9 can be transmitted to the cylindrical mold through the rotating shaft 1.

[0054] Place the raw materials (soft felt, carbon cloth, mesh tire, non-woven fabric, etc.) on the cylindrical mold, start the motor 9 to rotate the cylindrical mold to wrap the raw materials, and spray resin while wrapping.

[0055] After wrapping according to the process requirements, it needs to be sent to the oven for drying. If there is no empty space in the oven, the cylindrical mold needs to continue rotating continuously to ensure that the sprayed resin is evenly distributed in the carbon-carbon composite material barrel, and the resin will not flow to one side due to gravity when the rotation stops, ensuring the uniformity of the material. When there is an empty space in the oven, stop the operation of the motor 9, separate the drive frame 11, and send the tooling rack 12 into the oven for drying. There should be a corresponding motor in the oven to dock with the cylindrical mold to make it rotate continuously in the oven.

[0056] After the oven drying process is completed, push the tooling rack 12 out of the oven, reconnect the motor 9 and the rotating shaft 1 with the coupling 10, and at the same time lock the outer spring lock 7 to lock the rotational freedom between the side plate 4 and the tooling rack 12.

[0057] Then unlock the inner spring lock 7 to release the rotational freedom between the side plate 4 and the groove plate 2, and start the motor 9. The motor 9 drives the rotating shaft 1 to rotate through the coupling 10, the rotating shaft 1 drives the groove plate 2 to rotate through the key, and the arc-shaped chute 21 on the groove plate 2 drives the support rod 3 to change the shape of the outer cylinder piece 5 and the inner cylinder piece 6, and they fold inward.

[0058] At this time, separate the motor 9 and unlock the outer spring lock 7, then the cylindrical mold can be directly lifted to take off the baked carbon-carbon composite material barrel and transfer it to the warehouse.

[0059] After taking off the carbon-carbon composite material barrel, put the cylindrical mold back on the tooling rack 12, lock the outer spring lock 7, and connect the motor 9. Start the motor 9 to change the shape of the outer cylinder piece 5 and the inner cylinder piece 6 to expand outward, and finally lock the inner spring lock 7 to fix the cylindrical mold in the expanded state.

[0060] Unlock the outer spring lock 7, and it will return to the initial state. You can choose to continue wrapping the carbon-carbon composite material barrel, or you can choose to separate the motor 9 and remove the cylindrical mold to end the work.

[0061] The demoulding mechanism of the carbon-carbon composite material barrel provided by the present invention has been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
