Description

Technical Field

[0001] The present application relates to the technical field of fiber winding equipment, and particularly relates to a mold for cylindrical fiber winding products and a rotary winding machine. Background Art

[0002] A winding product mold is a special mold for manufacturing winding products. Winding products are usually made by winding materials (such as fibers, wires, etc.) around the mold in a specific manner and then through processes such as curing and demolding. The design of this kind of mold needs to consider factors such as the shape, size, and material of the product to ensure the quality and performance of the product.

[0003] The prior art discloses a mold tooling and a fiber winding curing system, which includes a support frame, a driving motor, and a mold component provided on the support frame; the mold component includes a hollow cylindrical body, end caps are respectively arranged at both ends of the cylindrical body, a rotating shaft is coaxially arranged on the end face of the end cap, and a through hole communicating with the inside of the cylindrical body is opened on the rotating shaft; and a plurality of annular windshields are arranged at intervals along the axial direction on the inner peripheral wall surface of the cylindrical body; at least one ventilation hole penetrating through both end faces of the plate body is opened in the circumferential direction of at least one of the windshields.

[0004] In view of the above related technologies, during the fiber winding process, the nozzle on the machine reciprocates along the axial direction of the cylindrical body and simultaneously spits out fibers. However, due to the relatively smooth surface of the cylindrical body, after the fibers are wound onto the cylindrical body, they will be driven by the fibers pulled out during the reciprocating movement of the nozzle, resulting in uneven distribution of the fiber thickness along the axial direction of the cylindrical body, causing the thickness of the cured product not to meet the requirements and affecting the quality of the fiber winding product. Content of the Utility Model

[0005] In order to reduce the possibility that the fibers wound on the cylindrical body are driven by the fibers spit out by the nozzle before curing, resulting in uneven fiber thickness distribution, the present application provides a mold for cylindrical fiber winding products and a rotary winding machine.

[0006] The mold for cylindrical fiber winding products and the rotary winding machine provided by the present application adopt the following technical solutions:

[0007] In a first aspect, the present application provides a mold for cylindrical fiber winding products.

[0008] A mold for cylindrical fiber winding products includes:

[0009] A cylindrical body;

[0010] Two mounting end caps, the two mounting end caps are respectively connected to the axial ends of the cylindrical body, and an inclined surface locking body is connected between the mounting end cap and the cylindrical body, and the outer diameter of the inclined surface locking body gradually increases toward the cylindrical body side;

[0011] A rotating shaft, which is connected to the mounting end cover, and the rotating shaft is coaxially arranged with the cylinder body.

[0012] By adopting the above technical solution, the rotating shaft is fixed to the rotating output end of the winding machine. The winding machine drives the mounting end cover to rotate through the rotating shaft. While the mounting end cover rotates, it drives the cylinder body to rotate through the inclined surface locking body. At the same time, the nozzle on the winding machine reciprocates axially along the rotating shaft and spits out fiber filaments to wind around the cylinder body and the inclined surface locking body. Due to the existence of the inclined surface locking body, when the fiber filaments are wound onto the inclined surface locking body, it will impose a certain position limitation on the fiber filaments, thereby reducing the possibility that the reciprocating movement of the nozzle pulls the fiber filaments that have already been wound onto the cylinder body, resulting in uneven fiber distribution on the outer peripheral side of the cylinder body, and thus ensuring the quality of the fiber-wound product after curing.

[0013] In a specific feasible embodiment, a cutting groove is recessed on the side of the inclined surface locking body close to the cylinder body, and the cutting groove is coaxially arranged with the rotating shaft.

[0014] By adopting the above technical solution, before curing after the fiber winding is completed, the fiber filaments wound around the cylinder body and the inclined surface locking body are cut along the cutting groove by a tool, then the fiber filaments on the outer peripheral side of the inclined surface locking body are removed, and then the fiber filaments on the outer side of the cylinder body are cured. Thus, the fiber filaments that play a position-limiting role are separated from the product blank fiber filaments, and the damage to the outer peripheral side of the cylinder body by the tool can be reduced.

[0015] In a specific feasible embodiment, the cylinder body is hollow.

[0016] By adopting the above technical solution, the designed hollow cylinder body can reduce the self-weight of the mold on the premise of realizing the function of the fiber winding mandrel, which is convenient for handling and installation.

[0017] In a specific feasible embodiment, the cylinder body includes at least three arc-shaped pieces, the arc-shaped pieces are coaxially arranged with the rotating shaft, and a hollow inner cavity is formed after splicing of multiple arc-shaped pieces. The inclined surface locking body includes at least three locking segments, the locking segments are coaxially arranged with the rotating shaft, and the locking segments are connected to the arc-shaped pieces, and the locking segments are detachably and fixedly connected to the mounting end cover.

[0018] By adopting the above technical solution, the rotating shaft is fixed to the rotating output end of the winding machine, and the winding machine drives the installation end cover to rotate through the rotating shaft. While the installation end cover rotates, the barrel is driven to rotate through the inclined locking body. At the same time, the nozzle on the winding machine reciprocates along the axial direction of the rotating shaft and spits out fiber filaments to be wound around the barrel and the inclined locking body. Due to the existence of the inclined locking body, when the fiber filaments are wound around the inclined locking body, a certain position limitation is caused to the fiber filaments, so that the thickness of the fiber filaments on the outer peripheral side of the barrel is evenly distributed until the thickness of the fiber filaments on the outer peripheral side of the barrel reaches the requirement. , and then use a tool to cut off the fibers on the outer periphery of the inclined locking body, and then solidify the fibers on the outer periphery of the cylinder to obtain the product. At this time, first remove the installation end cover on one side, and then apply force to the product to make the installation axis in a vertical state, and then remove the installation end cover on the other side, and then apply force to the arc piece to make the arc piece move toward one side of the rotating shaft until the arc piece is separated from the product, thereby avoiding damage to the product during demolding, and multiple arc pieces are spliced together to form a cylinder, which can also reduce the maintenance cost when the cylinder is damaged, and only the damaged arc piece needs to be replaced.

[0019] In a specific possible implementation mode, an inner groove is provided on the sub-locking segment, and the inner grooves on two adjacent sub-locking segments cooperate to form a through hole.

[0020] By adopting the above technical solution, the designed inner groove can form a through hole for operation after splicing, thereby facilitating the application of force to the arc piece or the locking segment to separate the arc piece from the product.

[0021] In a specific possible implementation mode, a joint gap between at least one of the arc-shaped pieces and an adjacent arc-shaped piece is staggered with respect to the axis of the rotating shaft.

[0022] By adopting the above technical solution, it is convenient to apply force to the arc-shaped piece so that the arc-shaped piece moves toward one side of the rotating shaft to achieve separation from the product.

[0023] In a second aspect, the present application provides a rotary winding machine.

[0024] A rotary winding machine comprises a winding machine body and a cylindrical fiber winding product mold, wherein the rotating shaft is rotatably connected to the winding machine body.

[0025] By adopting the above technical solution, the rotating shaft is fixed to the rotating output end of the winding machine. The winding machine drives the cylinder body and the mounting end cover to rotate through the rotating shaft. At the same time, the nozzle on the winding machine reciprocates axially along the rotating shaft and spits out fiber filaments to wind around the cylinder body and the mounting end cover. Due to the existence of the inclined surface of the mounting end cover, when the fiber filaments wind around the mounting end cover, it will impose a certain position limitation on the fiber filaments, thereby reducing the possibility that the reciprocating movement of the nozzle pulls the fiber filaments that have already been wound around the cylinder body, resulting in uneven fiber distribution on the outer peripheral side of the cylinder body, and thus ensuring the quality of the fiber-wound product after curing.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. For the designed mold for cylindrical fiber-wound products, the rotating shaft is fixed to the rotating output end of the winding machine. The winding machine drives the mounting end cover to rotate through the rotating shaft. While the mounting end cover rotates, it drives the cylinder body to rotate through the inclined surface locking body. At the same time, the nozzle on the winding machine reciprocates axially along the rotating shaft and spits out fiber filaments to wind around the cylinder body and the inclined surface locking body. Due to the existence of the inclined surface locking body, when the fiber filaments wind around the inclined surface locking body, it will impose a certain position limitation on the fiber filaments, thereby reducing the possibility that the reciprocating movement of the nozzle pulls the fiber filaments that have already been wound around the cylinder body, resulting in uneven fiber distribution on the outer peripheral side of the cylinder body, and thus ensuring the quality of the fiber-wound product after curing.

[0028] 2. For the designed mold for cylindrical fiber-wound products, before curing after fiber winding is completed, the fiber filaments wound around the cylinder body and the inclined surface locking body are cut along the cutting groove by a tool, then the fiber filaments on the outer peripheral side of the inclined surface locking body are removed, and then the fiber filaments on the outer side of the cylinder body are cured, thereby separating the fiber filaments that play a position-limiting role from the product blank fibers and being able to reduce the damage of the tool to the outer peripheral side of the cylinder body.

[0029] 3. For the designed cylindrical fiber winding product mold, the rotating shaft is fixed to the rotating output end of the winding machine. The winding machine drives the installation end cover to rotate through the rotating shaft. While the installation end cover rotates, it drives the cylinder to rotate through the inclined plane locking body. At the same time, the nozzle on the winding machine reciprocates axially along the rotating shaft and spits out fiber filaments to wind around the cylinder and the inclined plane locking body. Due to the existence of the inclined plane locking body, when the fiber filaments wind onto the inclined plane locking body, it will impose a certain position limitation on the fiber filaments, making the thickness distribution of the fiber filaments on the outer peripheral side of the cylinder uniform. Until the thickness of the fiber filaments on the outer peripheral side of the cylinder meets the requirements, then the fiber on the outer peripheral side of the inclined plane locking body is cut off by a tool, and then the fiber on the outer peripheral side of the cylinder is cured to obtain the product. At this time, first remove the installation end cover on one side, then apply force to the product to make the installation shaft in a vertical state, then remove the installation end cover on the other side, and then apply force to the arc-shaped piece to make the arc-shaped piece move toward the rotating shaft side until the arc-shaped piece is separated from the product, thus avoiding damage during product demolding. And multiple arc-shaped pieces are spliced together to form the cylinder, which can also reduce the maintenance cost when the cylinder is damaged. Only the damaged arc-shaped piece needs to be replaced. Brief Description of the Drawings

A bevel locking body 3 is connected between the mounting end cap 2 and the cylinder body 1. The outer diameter of the bevel locking body 3 gradually increases towards the side of the cylinder body 1. The rotating shaft 4 is coaxially arranged with the cylinder body 1, and the rotating shaft 4 is connected to the mounting end cap 2; in this application, the rotating shaft 4 can be one, and the rotating shaft 4 passes through the cylinder body 1, or the rotating shaft 4 can be two, and the two rotating shafts 4 are respectively connected to the two ends of the cylinder body 1. As long as it can cooperate with the winding machine to realize the rotation of the cylinder body 1. In this embodiment, the rotating shaft 4 is one and passes through the cylinder body 1. Due to the existence of the bevel locking body 3, when the fiber filament winds onto the bevel locking body 3, it will impose a certain position limitation on the fiber filament, thereby reducing the possibility that the nozzle moves back and forth to pull the fiber that has already wound onto the cylinder body 1, resulting in uneven fiber distribution on the outer peripheral side of the cylinder body 1, and thus ensuring the quality of the fiber-wound product after curing.

[0038] Refer to Figure 1 and Figure 2 , Before curing the fiber, it is necessary to cut the fiber on the outer peripheral side of the cylinder body 1 and the fiber on the outer peripheral side of the mounting end cap 2. In order to reduce the damage to the outer peripheral side of the cylinder body 1 during cutting, a cutting groove 31 is recessed on the side of the bevel locking body 3 close to the cylinder body 1, and the cutting groove 31 is coaxially arranged with the rotating shaft 4.

The sub-locking segments 32 are coaxially arranged with the rotating shaft 4, and the sub-locking segments 32 are integrally connected to the arc-shaped pieces 11. The sub-locking segments 32 and the mounting end cap 2 are detachably fixedly connected by bolts; in this application, the number of arc-shaped pieces 11 and sub-locking segments 32 is the same, which can be three, four, five, or other numbers. As long as it can meet the use requirements of the cylinder body 1. In this embodiment, the number of arc-shaped pieces 11 is five.

[0040] Refer to Figure 2 and Figure 3In order to facilitate the detachment of the fibers wound on the inclined locking body 3, an inner groove 33 is formed on the locking segment 32, and the inner grooves 33 close to each other on two adjacent locking segments 32 cooperate to form a through hole. The number of through holes in the present application can be one, two, or three. In the present embodiment, the number of through holes is four, and the four through holes are evenly distributed around the circumference of the rotating shaft 4.

[0041] Reference Figure 2 and Figure 3 , fix the rotating shaft 4 to the rotating output end of the winding machine, the winding machine drives the mounting end cover 2 to rotate through the rotating shaft 4, and the mounting end cover 2 drives the cylinder 1 to rotate through the inclined locking body 3. At the same time, the nozzle on the winding machine reciprocates along the axial direction of the rotating shaft 4 and spits out fiber filaments to be wound on the cylinder 1 and the inclined locking body 3. Due to the existence of the inclined locking body 3, when the fiber filaments are wound on the inclined locking body 3, a certain position limitation will be caused to the fiber filaments, so that the thickness of the fiber filaments on the outer peripheral side of the cylinder 1 is evenly distributed until the thickness of the fiber filaments on the outer peripheral side of the cylinder 1 meets the requirements, and then the fibers on the outer peripheral side of the inclined locking body 3 are cut off by a tool, and then the fibers on the outer peripheral side of the cylinder 1 are solidified to obtain the product. At this time, first remove the mounting end cover 2 on one side, and then apply force to the product to make the mounting shaft in a vertical state, and then remove the mounting end cover 2 on the other side, and then apply force to the arc piece 11, so that the arc piece 11 moves toward one side of the rotating shaft 4 until the arc piece 11 is separated from the product, thereby avoiding damage to the product during demolding.

[0042] Reference Figure 2 and Figure 3 In order to facilitate the application of force to the arc-shaped piece 11 so that the arc-shaped piece 11 moves toward the side of the rotating shaft 4 to achieve separation from the product, the splicing gap between at least one arc-shaped piece 11 and the adjacent arc-shaped piece 11 is staggered from the axis of the rotating shaft 4; in the present application, the number of arc-shaped pieces 11 that are staggered from the splicing gap between the adjacent arc-shaped pieces 11 and the axis of the rotating shaft 4 can be one or two, and in the present embodiment, it is one piece.

[0043] The implementation principle of a cylindrical fiber winding product mold in an embodiment of the present application is as follows: The rotating shaft 4 is fixed to the rotating output end of the winding machine. The winding machine drives the mounting end cover 2 to rotate through the rotating shaft 4. While the mounting end cover 2 rotates, it drives the cylinder body 1 to rotate through the inclined surface locking body 3. At the same time, the nozzle on the winding machine reciprocates along the axial direction of the rotating shaft 4 and spits out fiber filaments to wind around the cylinder body 1 and the inclined surface locking body 3. Due to the existence of the inclined surface locking body 3, when the fiber filaments wind around the inclined surface locking body 3, it will impose a certain position limitation on the fiber filaments, making the thickness distribution of the fiber filaments on the outer peripheral side of the cylinder body 1 uniform. Until the thickness of the fiber filaments on the outer peripheral side of the cylinder body 1 meets the requirements, then the fibers on the outer peripheral side of the inclined surface locking body 3 are cut off by a tool, and then the fibers on the outer peripheral side of the cylinder body 1 are cured to obtain the product. At this time, first remove the mounting end cover 2 on one side, then apply force to the product to make the mounting shaft in a vertical state, then remove the mounting end cover 2 on the other side, and then apply force to the arc-shaped piece 11 to make the arc-shaped piece 11 move towards the side of the rotating shaft 4 until the arc-shaped piece 11 is separated from the product, thereby avoiding damage to the product during demolding. And multiple arc-shaped pieces 11 are spliced together to form the cylinder body 1, which can also reduce the maintenance cost when the cylinder body 1 is damaged.

While the mounting end cover 2 rotates, it drives the cylinder body 1 to rotate through the inclined surface locking body 3. At the same time, the nozzle on the winding machine reciprocates along the axial direction of the rotating shaft 4 and spits out fiber filaments to wind around the cylinder body 1 and the inclined surface locking body 3. Due to the existence of the inclined surface locking body 3, when the fiber filaments wind around the inclined surface locking body 3, it will impose a certain position limitation on the fiber filaments, thereby reducing the possibility that the reciprocating movement of the nozzle pulls the fibers that have already wound around the cylinder body 1, resulting in uneven fiber distribution on the outer peripheral side of the cylinder body 1, and thus ensuring the quality of the fiber winding product after curing.
