Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, specifically to a multi-mold pultrusion device for composite material frames. Background Technology

[0002] Composite material frames are widely used in aerospace, rail transportation, and construction due to their lightweight, high strength, and corrosion resistance. In their manufacturing process, pultrusion technology relies on the continuous traction of resin-impregnated reinforcing materials, allowing them to rapidly cure and solidify through a heated mold. The traction device, as the core component of the pultrusion system, needs to apply stable traction force to the semi-formed frame during the high-temperature curing stage. Chinese Patent CN115071172B discloses a multi-layer pultrusion production line suitable for photovoltaic fiber composite material frames, including a multi-layer yarn rack, fiber distribution plate, glue injection box, multi-layer curing mold, traction machine, and traction force compensation mechanism. The traction machine includes a main traction machine and a circulating traction machine with identical structures and sequentially arranged production stations. Two sets of reciprocating traction machines alternately clamp and pull the frame, achieving stable movement of the frame through cyclic operation. The traction machine includes a support frame and clamping and pressure-bearing components mounted on the support frame.

[0003] However, during the traction process, when the upper clamping assembly of one traction machine is lifted and disengaged, its corresponding lower pressure-bearing assembly remains in contact with the bottom of the composite material. As the composite material moves with another traction machine, the released pressure-bearing assembly adheres to the surface of the composite material, resulting in continuous friction. This can easily cause scratches and dents, affecting the smoothness and appearance of the composite material surface. Furthermore, the continuous contact and long-term friction of the pressure-bearing assembly with the composite material can cause wear on its working surface, affecting the adhesion between the pressure-bearing assembly and the lower surface of the composite material, thus reducing clamping stability. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a multi-mold pultrusion device for composite material frames.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-mold pultrusion device for composite material frames, including a traction machine, the traction machine including a support base and a clamping device, and also including an upper clamp, a lower clamp and a lifting device. The upper clamp is fixedly installed at the bottom moving end of the support base, and the lower clamp is slidably installed at the bottom of the support base. The upper clamp and the lower clamp are arranged in a corresponding manner. The composite material passes through the gap between the upper clamp and the lower clamp. The lifting device is fixedly installed at the bottom of the inner side of the support base. The lifting component includes a rotating seat, a rotating plate, a pressure plate, and a lifting rod. The rotating seat is fixedly installed on the inner bottom of the support base. The rotating plate is rotatably installed inside the rotating seat. The pressure plate is fixedly installed at one end of the rotating plate, and the lifting rod is fixedly installed at the other end of the rotating plate. The pressure plate is located below the pressing ends on both sides of the upper clamp, and the lifting rod is set to fit against the bottom surface of the lower clamp.

[0006] The support base includes a main board, a base, and a tray. The base is fixedly installed on the bottom of the main board, and the tray is fixedly installed inside the main board. The rotating seat is fixedly installed on the inner bottom of the main board.

[0007] The clamping device includes an electric push rod, a pressure column, a pressure plate, and a guide column. The electric push rod is fixedly installed on the top of the tray. The output end of the electric push rod passes through the top of the tray and is fixedly connected to the pressure column. The pressure plate is fixedly installed at the bottom end of the pressure column. The guide column is slidably inserted into the top of the tray, and the bottom end of the guide column is connected to the top of the pressure plate.

[0008] The upper clamp includes an upper fixing plate, a pressing module, side plates, a screw, and a pressure block. The upper fixing plate is fixedly installed at the bottom of the pressure plate. The pressing module is fixedly installed at the bottom of the upper fixing plate. Side plates are fixedly installed on both sides of the upper fixing plate. The side plates have through grooves inside. The pressure block is slidably sleeved on the bottom of the side plates. The pressure plate is located below the pressure block.

[0009] The screw is rotatably installed inside the through groove of the side plate, and a dial is fixedly installed on the top of the screw. The screw and the pressure block are threaded together.

[0010] The lower clamp includes a lower fixed plate, a support module, and a sliding column. The support module is fixedly installed on the top of the lower fixed plate, and a vertically arranged sliding column is fixedly installed on the bottom of the lower fixed plate. The sliding column is slidably inserted into the bottom of the main board.

[0011] The beneficial effects of this utility model are as follows: This invention uses a clamping fastener to move the upper clamping fixture downwards, causing the pressing module to approach the top surface of the composite material. Simultaneously, the upper fixing plate moves the pressure block at the bottom of the side plate downwards, bringing it into contact with the pressure plate. This causes the rotating plate to flip along the rotating seat, and the lifting rod rotates upwards, pushing the lower clamping fixture upwards. This brings the support module closer to the bottom surface of the composite material. The pressing module and support module clamp and fix the composite material tightly against its upper and lower sides. When the pressing module and support module release their fixation of the composite material, the pressing module moves upwards with the moving end of the clamping fastener, separating from the composite material. At this point, the pressure block no longer applies pressure to the pressure plate, and the lifting rod loses its supporting force on the lower fixing plate. The lower fixing plate falls freely under the guidance of the sliding column, separating from the composite material. This avoids incomplete separation between the clamping fixture and the composite material, which could lead to continuous friction during the traction of the composite material and affect product quality. By turning the dial, the screw is rotated, which in turn causes the pressure block to make fine adjustments to its vertical position at the bottom of the side plate. This allows for clamping and fixing of composite materials by pressing modules and support modules of different sizes. Attached Figure Description

[0015] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 5 The present invention will be further described below.

[0016] A multi-mold pultrusion device for composite material frames includes a traction machine, which includes a support base 1 and a clamping device 2, as well as an upper clamp 3, a lower clamp 4 and a lifting device 5. The clamping device 2 is provided on the inner top of the support base 1, and the upper clamp 3 is fixedly installed on the bottom movable end of the clamping device 2. The lower clamp 4 is slidably installed on the inner bottom of the support base 1. The upper clamp 3 and the lower clamp 4 are arranged correspondingly. The composite material passes through the gap between the upper clamp 3 and the lower clamp 4. The lifting device 5 is fixedly installed on the inner bottom of the support base 1. One side of the rotating end of the lifting device 5 is located below the two pressing ends of the upper clamp 3, and the other side of the rotating end of the lifting device 5 is attached to the bottom surface of the lower clamp 4. There are two sets of lifting devices 5, and the two sets of lifting devices 5 are arranged symmetrically about the pressing end of the upper clamp 3 on its front and rear sides. Specifically, the support base 1 moves horizontally in the front-to-back direction, thereby driving the composite material fibers connected to the device to move and pull, and stably perform pultrusion processing. The clamping fastener 2 pushes the upper clamp 3 to move up and down, so that the upper clamp 3 and the lower clamp 4 clamp and fix the composite material fibers. The pressing end of the upper clamp 3 contacts the lifting member 5, so that the lifting member 5 pushes the lower clamp 4 to lift slightly, keeping the top of the lower clamp 4 in contact with the bottom of the composite material.

[0017] The support base 1 includes a main board 101, a base 102 and a tray 103. The base 102 is fixedly installed on the bottom of the main board 101, and the tray 103 is fixedly installed inside the main board 101. Specifically, the base 102 is connected to the drive assembly of the pultrusion production line. The drive assembly drives the support 1 to move back and forth. The drive assembly can use a lead screw and nut to drive the base 102. In this method, the base 102 has an internal thread. Alternatively, other existing linear drive structures can be used to drive the support 1.

[0018] The clamping component 2 includes an electric push rod 201, a pressure column 202, a pressure plate 203, and a guide column 204. The electric push rod 201 is fixedly installed on the top of the support plate 103. The output end of the electric push rod 201 passes through the support plate 103 and is fixedly connected to the pressure column 202. The pressure plate 203 is fixedly installed at the bottom end of the pressure column 202. The left and right sides of the pressure plate 203 are in contact with the inner wall of the main plate 101. The guide column 204 is slidably inserted into the surface of the support plate 103, and the bottom end of the guide column 204 is connected to the top of the pressure plate 203. There are two sets of guide columns 204, which are symmetrically arranged on the left and right sides of the electric push rod 201. Specifically, the electric push rod 201 pushes the pressure column 202 to move up and down, which drives the upper clamp 3 at the bottom of the pressure plate 203 to perform clamping and loosening operations. The guide column 204 guides the vertical movement of the pressure plate 203 to be more stable.

[0019] The upper clamp 3 includes an upper fixed plate 301, a pressing module 302, a side plate 303, a screw 304, and a pressure block 305. The upper fixed plate 301 is fixedly installed on the bottom of the pressure plate 203. The pressing module 302 is fixedly installed on the bottom of the upper fixed plate 301. The side plates 303 are fixedly installed on both sides of the upper fixed plate 301. The side plates 303 have through slots inside. The screw 304 is rotatably installed in the through slots of the side plates 303. A dial is fixedly installed on the top of the screw 304. The pressure block 305 is slidably sleeved on the bottom of the side plates 303. The screw 304 and the pressure block 305 are threadedly connected. There are two sets of side plates 303, screws 304, and pressure blocks 305, which are symmetrically arranged on the left and right sides of the upper fixed plate 301. Specifically, the pressing module 302 contacts the top surface of the composite material to clamp and fix it, and the screw 304 rotates inside the through groove of the side plate 303, thereby driving the pressing block 305 to move up and down along the bottom surface of the side plate 303.

[0020] The lower clamp 4 includes a lower fixing plate 401, a support module 402 and a sliding column 403. The support module 402 is fixedly installed on the top of the lower fixing plate 401, and the vertically arranged sliding column 403 is fixedly installed on the bottom of the lower fixing plate 401. The sliding column 403 is slidably inserted into the bottom of the main board 101. Specifically, the support module 402 contacts the bottom surface of the composite material to clamp and fix it, and the sliding column 403 allows the lower fixing plate 401 to slide up and down at the bottom of the main board 101.

[0021] The lifting component 5 includes a rotating seat 501, a rotating plate 502, a pressure plate 503, and a lifting rod 504. The rotating seat 501 is fixedly installed on the inner bottom of the main board 101. The rotating plate 502 is rotatably installed inside the rotating seat 501. The pressure plate 503 is fixedly installed at one end of the rotating plate 502 and is located below the pressure block 305. The lifting rod 504 is fixedly installed at the other end of the rotating plate 502 and fits against the bottom of the lower fixed plate 401. There are two sets of rotating seats 501, rotating plates 502, and pressure plates 503, which are symmetrically arranged on the left and right sides of the lower fixed plate 401. The other end of both sets of rotating plates 502 is connected to the lifting rod 504. Specifically, the rotating plate 502 is supported by the rotating seat 501 to rotate inside it, so that the pressure plate 503 and lifting rod 504 at both ends of the rotating plate 502 are pressed by the upper clamp 3 to lift the lower clamp 4. The pressure plate 503 contacts the pressure block 305 to control the rotation of the rotating plate 502. The lifting rod 504 is attached to the bottom of the lower fixed plate 401 to push the lower fixed plate 401 to move upward.

[0022] In summary: When using this utility model, during the pultrusion molding of composite material frames, the operator drives two sets of this device to clamp, pull, release, and reset the composite material in an alternating manner. When fixing the composite material, the electric push rod 201 drives the pressure column 202 downwards. Guided by the guide column 204, the pressure plate 203 at its bottom drives the upper clamp 3 to move stably downwards. As the pressing module 302 at the bottom of the upper fixing plate 301 approaches the top surface of the composite material, the pressure block 305 at the bottom of the side plate 303 contacts the pressure plate 503, thereby pushing the rotating plate 502 to flip along the rotating seat 501. One end of the pressure plate 503 descends, and one end of the lifting rod 504 rises, causing the lifting rod 504 to drive the lower fixing plate 401 to move stably upwards under the guidance of the sliding column 403. The top surface of the support module 402 approaches the bottom surface of the composite material until the pressing module 302 and the support module 402 adhere to the upper and lower sides of the composite material to complete the clamping and fixing. The external drive assembly drives the traction machine to move, thereby fixing the composite material. During the pulling process, when the composite material is released and reset, the drive electric push rod 201 moves the upper clamp 3 upward, causing the pressing module 302 to separate from the top surface of the composite material. Simultaneously, due to the loss of pressure from the pressure block 305 on the pressure plate 503, under the gravity of the lower fixed plate 401, one end of the lifting rod 504 descends, the rotating plate 502 flips in the opposite direction, and one end of the pressure plate 503 rises, causing the support module 402 to separate from the bottom surface of the composite material. This ensures that during the pulling process of the composite material, the traction machine and its... Fully separate to avoid continuous friction between the two, which would affect product quality. The external drive component moves the device, thereby resetting it. For composite materials of different sizes, different models of pressing module 302 and support module 402 need to be selected. As needed, the dial can be turned to drive the screw 304 to rotate inside the through groove of the side plate 303, so that the screw 304 controls the pressure block 305 to make slight up and down adjustments on the bottom surface of the side plate 303, changing the contact timing between the pressure block 305 and the pressure plate 503.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
