[0003] When using the current composite beam forming tool, the composite beam sheet is placed inside the forming tool mold, and the composite material is heated and softened using a heating device.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0020] During the use of traditional composite beam forming tooling, the composite material sheet is placed inside the mold, and the composite material sheet is heated by a heating device to soften the composite material. The composite material sheet is then plasticized by the top mold and the bottom mold. The composite material needs to cool before it can be demoulded. During the cooling process of the composite material, the heat generated by the heating device is slowly dissipated to the outside. This method does not fully utilize the heat generated by the heating device, resulting in high molding costs for composite beams.

[0021] In view of this, the utility model provides a composite beam forming tool, which uses a heating plate to heat and soften the composite plate, moves the softened plate to the mold through a displacement device, and plasticizes the softened plate through the mold. After the heating plate softens the composite plate, the plate is transferred to another place for plasticization, and the heating plate can continue to soften the composite plate. This method fully utilizes the heat generated by the heating device and reduces the forming cost of the composite beam.

[0022] Example 1: By Figure 1 、 2 , 3 and 4 show that a composite beam forming tool comprises a tool body 1, a vertical cylinder 3 is installed inside the tool body 1, a bottom mold 6 is installed on the top of the vertical cylinder 3, an outer frame 7 is installed on the outer wall of the tool body 1, a cylinder 8 is installed inside the outer frame 7, an upper mold 9 is installed on the output end of the cylinder 8, and a plurality of heating plates 11 are installed on the outer wall of the tool body 1. The composite beam forming tool further comprises: a transposition device 2, which is installed inside the tool body 1; a demoulding device 4 is installed inside the vertical cylinder 3; and a cooling device 5, which is installed on the outer wall of the bottom mold 6; wherein the transposition device 2 can adjust the position of the composite material plate after heating and softening, the demoulding device 4 can demould the cooled composite material beam, and the cooling device 5 can accelerate the cooling speed of the composite material beam;

[0023] During the specific implementation process, it is worth noting that the model of the cylinder 8 is SCA2-CB-100B-300-T0H3-DY, the model of the heating plate 11 is YK-3, the composite material sheet is placed inside the transposition device 2, the heating plate 11 heats and softens the composite material sheet, the softened composite material sheet is transferred to the bottom of the upper mold 9, the cylinder 8 is used to drive the upper mold 9 to move downward, the upper mold 9 cooperates with the bottom mold 6 to plasticize the composite material sheet, the cooling device 5 is used to cool and shape the plastic composite material beam, and the composite material beam is demolded from the bottom mold 6 by the demolding device 4;

[0024] Furthermore, a control panel 10 is installed on the outer wall of the tooling body 1, and the control panel 10 is electrically connected to the cylinder 8 and the heating plate 11;

[0025] In the specific implementation process, it is worth noting that the control panel 10 controls whether the cylinder 8 and the heating plate 11 are working;

[0026] Specifically, when using the composite beam forming tooling, the control panel 10 controls the temperature of the heating plate 11 by controlling the magnitude of the current. When the heating plate 11 is working, the composite plate is heated and softened. The displacement device 2 displaces the plate, and the cylinder 8 drives the upper mold 9 to move. The upper mold 9 cooperates with the bottom mold 6 to reduce the plasticity of the composite plate into a composite beam. The cooling device 5 is used to accelerate the cooling speed of the composite plate. After the composite beam is cooled, the demolding device 4 is used to demold the composite beam.

[0027] Example 2: By Figure 1 、 2 , 3 and 4 show that the transposition device 2 includes: a gear 201, which is rotatably connected to the inside of the tooling body 1 through a bearing; a cone plate 202, which is installed on the front of the gear 201; a round rod 203, which is arranged on one side of the cone plate 202; a tooth plate 204, which is rotatably connected to the inside of the tooling body 1 through a bearing and is fixedly connected to the outer wall of the round rod 203; a first servo motor 205, which is detachably connected to the inside of the tooling body 1 and is detachably connected to the front of the tooth plate 204, and the first servo motor 205 is electrically connected to the control panel 10; a placement slot 206, which is installed on the outer wall of the gear 201; wherein, when the first servo motor 205 is working, it drives the round rod 203 to rotate through the tooth plate 204, and the round rod 203 drives the gear 201 to rotate 180 degrees by shifting the cone plate 202, thereby driving the placement slot 206 to rotate 180 degrees;

[0028] In the specific implementation process, it is worth noting that the composite sheet is placed inside the placement groove 206 near the side of the heating plate 11, and the first servo motor 205 drives the gear plate 204 to rotate. After the gear plate 204 engages with the gear 201, it drives the gear 201 to rotate 180 degrees. The gear 201 drives the composite sheet inside the placement groove 206 to rotate 180 degrees. The model of the first servo motor 205 is SM80-D601930;

[0029] Specifically, based on the above-mentioned embodiment 1, the control panel controls the operation of the first servo motor 205, the first servo motor 205 drives the tooth plate 204 to rotate, the tooth plate 204 drives the round rod 203 to rotate, and the round rod 203 adjusts the angle of the gear 201 by toggling the cone plate 202. When the tooth plate 204 is engaged with the gear 201, the tooth plate 204 drives the gear 201 to rotate 180 degrees, and the gear 201 drives the placement groove 206 to rotate 180 degrees. The placement groove 206 moves the heated and softened composite sheet to the bottom of the upper mold 9, and adds the composite sheet to the other groove of the placement groove 206 for softening. This method can continuously soften the composite sheet and reduce the heat waste of the heating plate 11. When the tooth plate 204 is not engaged with the gear 201, the gear 201 limits the tooth plate 204 to prevent the placement groove 206 from rotating.

[0030] Example 3: By Figure 1 and 4 It can be seen that the demoulding device 4 includes: a second servo motor 401, which is detachably mounted inside the vertical cylinder 3 and electrically connected to the control panel 10; a threaded rod 402, which is detachably connected to the output end of the second servo motor 401; a slide 403, which is threadedly connected to the outer wall of the threaded rod 402 and is slidably engaged with the interior of the vertical cylinder 3; a stripping module 404, which is mounted above the slide 403 and is movably connected to the interior of the bottom mold 6; wherein, when the second servo motor 401 is in operation, the stripping module 404 on the slide 403 is driven to move upward via the threaded rod 402;

[0031] In the specific implementation process, it is worth noting that the model of the second servo motor 401 is SM80-D601930. When the second servo motor 401 is working, it drives the slide 403 to move upward through the threaded rod 402, and the slide 403 drives the stripping module 404 to move upward;

[0032] Specifically, based on the above-mentioned embodiment 1, the control panel 10 controls the operation of the second servo motor 401, the second servo motor 401 drives the threaded rod 402 to rotate, the threaded rod 402 drives the slide 403 to move upward, the slide 403 drives the stripping module 404 to move upward, and the stripping module 404 pushes out the composite material beam cooled and formed inside the bottom mold 6 to complete the demolding.

[0033] Example 4: By Figure 1 and 4 As can be seen, the cooling device 5 includes: two curved rods 501, both mounted on the outer wall of the vertical tube 3; two cooling fans 502, respectively mounted above the two curved rods 501 and electrically connected to the control panel 10; and two heat sinks 503, both mounted on the outer wall of the bottom mold 6. When the cooling fans 502 are in operation, they speed up the circulation of air around the heat sinks 503, thereby cooling the bottom mold 6.

[0034] During the specific implementation, it is worth noting that the cooling fan 502 is of model DBF-6.3Q6, and the heat sink 503 is made of metal with good thermal conductivity. The dispersed areas of the heat sink 503 increase the contact area with the air, thereby improving the heat dissipation effect. When the cooling fan 502 is in operation, the air circulation speed around the heat sink 503 is accelerated, and the bottom mold 6 transfers heat to the heat sink 503, thereby cooling the composite beam inside the mold 6.

[0035] Specifically, based on the above-mentioned embodiment 1, the control panel 10 controls the operation of the cooling fan 502, and the cooling fan 502 blows wind toward the heat sink 503. The air circulation speed around the heat sink 503 is fast, so that the temperature of the heat sink 503 is relatively low. The bottom mold 6 transfers heat to the heat sink 503, thereby cooling the composite material beam inside the mold 6.
