Description

Technical Field

[0001] The present application relates to the field of rapid bending, and in particular to a rapid bending device for thermoplastic composite reinforcement. Background Art

[0002] The rapid bending device can bend profiles quickly to a fixed angle, making them more convenient to use. Existing Zhewai devices can bend materials such as steel bars and thermoplastic composite bars. Because thermoplastic composite bars are relatively hard when unheated, they are usually heated and then bent using the rapid bending device. After being bent, the thermoplastic composite bars are cooled, allowing them to solidify and complete the bending process.

[0003] In the prior art, a rapid bending device for thermoplastic composite reinforcement includes a machine base, a fixed heating block and a sliding heating block are provided on the machine base, the fixed heating block and the sliding heating block cooperate to clamp the thermoplastic composite reinforcement, the machine base is provided with a driving member for driving the sliding heating block to move close to the fixed heating block, a bending block is provided on the machine base, a bending groove is provided on the outer wall of the bending block, a rotating rod is rotatably connected to the bending block, and a bending wheel is rotatably connected to the rotating rod, and the bending wheel cooperates with the bending groove to bend the heated thermoplastic composite reinforcement; the fixed heating block and the sliding heating block are heated by the fixed heating block and the sliding heating block, and the heated part is extended after the heating is completed, and under the action of the bending wheel and the bending groove, and in cooperation with the fixed heating block and the sliding heating block, the other parts of the thermoplastic composite reinforcement are clamped, so that the thermoplastic composite reinforcement can be quickly bent into a fixed angle.

[0004] With respect to the above-mentioned prior art, when the thermoplastic composite reinforcement is bent, the fixed heating block and the sliding heating block need to heat the thermoplastic composite reinforcement at the same time, and also need to be fixed when the thermoplastic composite reinforcement is bent. Since the thermoplastic composite reinforcement needs a certain amount of time to cool after bending, if the thermoplastic composite reinforcement is directly taken out for cooling after bending, it is easy to affect the bending angle of the thermoplastic composite reinforcement. If the thermoplastic composite reinforcement is heated for a long time, the softness of other parts will be affected. When the thermoplastic composite reinforcement is taken out, the shape of other parts of the thermoplastic composite reinforcement will be affected, reducing the effect of bending the thermoplastic composite reinforcement, which urgently needs to be improved. Summary of the Invention

[0005] In order to enable the fixed heating block and the sliding heating block to heat and clamp the thermoplastic composite reinforcement, reduce the impact on the thermoplastic composite reinforcement, and better ensure the bending effect of the thermoplastic composite reinforcement, the present application provides a rapid bending device for thermoplastic composite reinforcement.

[0006] The present application provides a rapid bending device for thermoplastic composite reinforcement using the following technical solutions:

[0007] The heating unit is equipped with a heating element for heating the thermoplastic composite material, and the heating element is installed in the heating element to heat the thermoplastic composite material.

[0008] By adopting the above technical solution, when working, the thermoplastic composite bar is clamped by two clamping pieces, and the driving member is used to drive the sliding heating block to press and fix the heating block, thereby achieving the purpose of clamping the thermoplastic composite bar, and the heating device is used to heat the thermoplastic composite bar; after the thermoplastic composite bar is heated for a period of time, the thermoplastic composite bar becomes soft, and then the thermoplastic composite bar is taken out and the heated thermoplastic composite bar is pushed out, and the clamping piece is inserted into the clamping groove at the same time, thereby achieving the function of heat insulation and fixing the thermoplastic composite bar, so that the thermoplastic composite bar can be fixed more stably, and then the rotating rod is rotated, and under the action of the bending wheel and the bending groove, the thermoplastic composite bar can be bent more conveniently, and a fan is used to accelerate the cooling of the thermoplastic composite bar. After cooling for a certain period of time, the thermoplastic composite bar is shaped, so that the thermoplastic composite bar can be better bent. Such a design can reduce the contact between the fixed heating block and the sliding heating block and other positions of the thermoplastic composite reinforcement, so that the fixed heating block and the sliding heating block can both heat and clamp the thermoplastic composite reinforcement, and reduce the impact on the thermoplastic composite reinforcement, thereby better ensuring the bending effect of the thermoplastic composite reinforcement.

[0009] Preferably, a sliding block is slidably connected to the machine base, and the sliding block moves along the sliding direction of the clamping plate. The bending block is detachably installed on the sliding block, and the fan is fixed to one end of the bending block that slides away from the fixed heating block. When the bending block moves away from the fixed heating block, the clamping plate moves closer to the fan.

[0010] By adopting the above technical solution, the clamping piece and the bending block move synchronously toward the fan, thereby ensuring that the bent thermoplastic composite bar moves in a fixed shape. The use of the fan to cool the thermoplastic composite bar can enable the thermoplastic composite bar to be cooled more quickly. In addition, the fan is set away from the fixed heating block to reduce the cooling effect of the fan on the fixed heating block, so that the fixed heating block and the sliding heating plate can better keep warm and reduce heat loss.

[0011] Preferably, a plug-in rod is provided on one side of the bending block close to the fixed heating block, and a plug-in groove for plugging with the plug-in rod is provided on the side wall of the fixed heating block.

[0012] By adopting the above technical solution, the plug-in rod cooperates with the plug-in groove, which can, on the one hand, guide the sliding of the bending block and improve the stability of the bending block. On the other hand, the plug-in rod is inserted into the fixed heating block, and the heat of the fixed heating block can heat the bending block through heat conduction, thereby increasing the surface temperature of the bending block and preventing the thermoplastic composite reinforcement from dropping in temperature suddenly during bending, so that the thermoplastic composite reinforcement can be bent better, ensuring the bending effect of the bending device on the thermoplastic composite reinforcement.

[0013] Preferably, the bending block is rotatably connected to one end away from the fixed heating block with a locking block, and a limiting cavity for plugging and cooperating with the thermoplastic composite reinforcement is provided on the bottom side of the locking block, and the thermoplastic composite reinforcement is stuck in the limiting cavity after being bent.

[0014] By adopting the above technical solution, after the thermoplastic composite bar is bent, the locking block is rotated to make the thermoplastic composite bar snap into the limiting cavity, thereby locking the thermoplastic composite bar. When the thermoplastic composite bar is relatively soft, the thermoplastic composite bar can be better fixed, thereby improving the stability of the thermoplastic composite bar in shaping.

[0015] Preferably, a pressing groove is provided on the bending block, and a rotating block is rotatably connected in the pressing groove. The rotating block consists of a limit block and a switch block. When the rotating rod bends the thermoplastic composite reinforcement, the rotating rod pushes the switch block to rotate close to the bending block, and at the same time, the limit block rises upward to limit the rotating rod. The side wall of the limit block is provided with a positioning protrusion, and the side wall of the pressing groove is provided with a plurality of positioning grooves that engage with the positioning protrusion. A switch part for controlling the fan switch is provided at the bottom of the pressing groove, and the rotating block is used to control the switch part to turn on and off.

[0016] By adopting the above technical solution, the rotating rod and the rotating block can cooperate to control the switch of the fan. When the rotating rod is rotated out, the fan can be turned on at the same time, which improves the convenience of using the fan, saves electricity, and improves the convenience of cooling the thermoplastic composite reinforcement. Under the action of the limit block and the rotating rod, the limit rod can be locked, which improves the convenience of using the rotating rod.

[0017] Preferably, a water trough is provided on the fan, and a plurality of drip holes connected to the water trough are provided at the bottom of the fan.

[0018] By adopting the above technical solution, water is injected into the water tank, and then used in conjunction with the drip holes, the water can be dripped onto the thermoplastic composite reinforcement, thereby better accelerating the cooling of the thermoplastic composite reinforcement and ensuring the molding effect of the thermoplastic composite reinforcement.

[0019] Preferably, the heating device comprises a heating plate fixed in the clamping groove, and a soft heat-conducting plate is provided on the heating plate.

[0020] By adopting the above technical solution, the soft thermal conductive sheet is used to conduct heat to the heating sheet, so that the thermoplastic composite reinforcement can be heated more conveniently. In addition, the soft thermal conductive sheet can be better adapted to the changes in thermoplastic composite reinforcements of different sizes, thereby improving the versatility of the bending device.

[0022] By adopting the above technical solution, when in use, the thermoplastic composite reinforcement can be placed between the two clamping pieces more conveniently, thereby improving the convenience of fixing the thermoplastic composite reinforcement. The sliding heating block can push the extrusion piece and drive the two clamping pieces to clamp each other, thereby pushing the two clamping pieces to hold the thermoplastic composite reinforcement tightly, thereby improving the stability of the thermoplastic composite reinforcement fixation.

[0023] Preferably, a tension spring is connected between the two extrusion pieces, and the tension spring is used to drive the two clamping pieces to move closer to each other.

[0024] By adopting the above technical solution, the stretching tool can be used to pull the two clamping pieces closer to each other and clamp the thermoplastic composite reinforcement, thereby improving the convenience of fixing the thermoplastic composite reinforcement.

[0025] Preferably, a friction groove is provided on the inner wall of the clamping piece, and a heat-resistant piece is provided on the outer wall of the clamping piece.

[0026] By adopting the above technical solution, the friction groove can be used to increase the friction between the clamping plate and the thermoplastic composite reinforcement, so that the clamping plate can lock the thermoplastic composite reinforcement more stably, thereby improving the stability of the locking of the thermoplastic composite reinforcement; and the use of the heat-blocking sheet can reduce the heat conduction to the clamping plate, thereby improving the convenience of using the clamping plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

Two clamping pieces are used to clamp the thermoplastic composite bar, and a driving member is used to drive the sliding heating block to press and fix the heating block, thereby achieving the purpose of clamping the thermoplastic composite bar, and the heating device is used to heat the thermoplastic composite bar; after the thermoplastic composite bar is heated for a period of time, the thermoplastic composite bar becomes soft, and then the thermoplastic composite bar is taken out and the heated thermoplastic composite bar is pushed out, and at the same time, the clamping piece is inserted into the clamping groove, thereby achieving the functions of heat insulation and fixing the thermoplastic composite bar, so that the thermoplastic composite bar can be fixed more stably, and then the rotating rod is rotated. Under the action of the bending wheel and the bending groove, the thermoplastic composite bar can be bent more conveniently, and a fan is used to accelerate the cooling of the thermoplastic composite bar. After cooling for a certain period of time, the thermoplastic composite bar is shaped, so that the thermoplastic composite bar can be bent better. This design can reduce the contact between the fixed heating block and the sliding heating block and other parts of the thermoplastic composite reinforcement, so that the fixed heating block and the sliding heating block can both heat and clamp the thermoplastic composite reinforcement, and reduce the impact on the thermoplastic composite reinforcement, thereby better ensuring the bending effect of the thermoplastic composite reinforcement.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1 - Figure 8 further explains this application in detail.

[0041] The embodiments of the present application disclose a rapid bending device for thermoplastic composite reinforcement.

[0042] Reference Figure 1A rapid bending device for thermoplastic composite reinforcement includes a machine base 1, on which are mounted a fixed heating block 2 and a sliding heating block 4. The fixed heating block 2 is fixed to the machine base 1, and the sliding heating block 4 is slidably mounted on the machine base 1. The sliding heating block 4 slides toward the fixed heating block 2. A clamping groove 6 for clamping the thermoplastic composite reinforcement is defined between the fixed heating block 2 and the sliding heating block 4. A heating device for heating the thermoplastic composite reinforcement is mounted within the clamping groove 6. A driving member 5, which is a pneumatic cylinder, is fixed to the machine base 1 and is used to drive the sliding heating block 4 toward the fixed heating block 2. Two clamping plates 3 for clamping the thermoplastic composite reinforcement are slidably connected to the machine base 1. When the clamping plates 3 slide between the fixed heating block 2 and the sliding heating block 4, the two clamping plates 3 clamp the thermoplastic composite reinforcement. A bending block 9 is installed on the machine base 1. The side wall of the bending block 9 is C-shaped, and the C-shaped side wall of the bending block 9 is provided with a bending groove 10. The bending block 9 is rotatably connected to a rotating rod 7, and the rotating rod 7 is rotatably connected to a bending wheel 8. The side wall of the bending wheel 8 is provided with a C-shaped side wall. The side wall of the bending wheel 8 cooperates with the bending groove 10 to bend the thermoplastic composite reinforcement, thereby making it easier to bend the thermoplastic composite reinforcement. A fan 11 is fixed to the machine base 1 for accelerating the cooling of the thermoplastic composite reinforcement. The fan 11 can accelerate the air flow around the thermoplastic composite reinforcement, thereby accelerating the reduction of the temperature. A rotating handle is provided on the side of the rotating rod 7 away from the bending block 9. The operator can rotate the rotating rod 7 more conveniently by turning the handle. The thermoplastic composite reinforcement is clamped by two clamping pieces 3, and the driving member 5 is used to drive the sliding heating block 4 to press the fixed heating block 2, so as to achieve the purpose of clamping the thermoplastic composite reinforcement, so that the fixed heating block 2 and the sliding heating block 4 can both heat and clamp the thermoplastic composite reinforcement, and reduce the impact on the thermoplastic composite reinforcement, thereby better ensuring the bending effect of the thermoplastic composite reinforcement.

[0043] A sliding block 36 is slidably connected to the machine base 1. The sliding block 36 moves along the sliding direction of the clamping plate 3. The bending block 9 is detachably mounted on the sliding block 36. A connecting screw 14 is provided on the sliding block 36. The connecting screw 14 passes through the bending block 9 and the rotating rod 7. A connecting nut 15 is threadedly connected to the connecting screw 14, and the bending block 9 is fixed by the connecting nut 15. The fan 11 is fixed to one end of the bending block 9 that slides away from the fixed heating block 2. When the bending block 9 moves away from the fixed heating block 2, the clamping plate 3 moves closer to the fan 11. Through such a design, the thermoplastic composite reinforcement can be lowered more quickly, and setting the fan 11 away from the fixed heating block 2 can reduce the cooling of the fixed heating block 2 by the fan 11, so that the fixed heating block 2 and the sliding heating plate 22 can be better insulated and reduce heat loss.

[0044] A plug-in rod 30 is integrally formed on one side of the bending block 9 close to the fixed heating block 2. The plug-in rod 30 is cylindrical, and its diameter direction is set along the sliding direction of the bending block 9. The side wall of the fixed heating block 2 is provided with a plug-in groove 29 that is plugged into the plug-in rod 30, so that the bending block 9 can slide more smoothly.

[0045] The end of the bending block 9 away from the fixed heating block 2 is rotatably connected to a locking block 13. The locking block 13 is a rectangular block. The bottom side of the locking block 13 is provided with a limiting cavity 37 for plugging and cooperating with the thermoplastic composite bar. The limiting cavity 37 is U-shaped, and the thermoplastic composite bar is snapped into the limiting cavity 37 after being bent. This allows the thermoplastic composite bar to be locked after bending, improving the convenience of cooling and forming the thermoplastic composite bar.

[0046] The bending block 9 is provided with a pressing groove 18, in which a rotating block is rotatably connected. The rotating block is composed of a limit block 17 and a switch block 16. When the rotating rod 7 bends the thermoplastic composite reinforcement, the rotating rod 7 pushes the switch block 16 to rotate closer to the bending block 9. At the same time, the limit block 17 rises upward to limit the rotating rod 7. The side wall of the limit block 17 is integrally formed with a positioning protrusion 33. The side wall of the pressing groove 18 is provided with a plurality of positioning grooves 35 that engage with the positioning protrusions 33. The bottom of the pressing groove 18 is fixed with a switch member 34 for controlling the switch of the fan 11. The switch member 34 is a push-type electric switch. By pressing the switch member 34 through the rotating block, the fan 11 can be turned on and off. The rotating rod 7 and the rotating block can control the switch of the fan 11. When the rotating rod 7 is rotated out, the fan 11 can be turned on at the same time, improving the convenience of using the fan 11.

[0047] The heating device includes a heating plate 22 fixed within the clamping groove 6. A soft thermally conductive sheet 21 is fixed to the heating plate 22. The soft thermally conductive sheet 21 is made of a soft thermally conductive silicone sheet. The soft thermally conductive silicone sheet allows for a more convenient and secure fixation of the thermoplastic composite bar. A sliding seat 24 is slidably connected to the base 1. The clamping plate 3 near the fixed heating block 2 is fixed to the sliding seat 24, while the clamping plate 3 near the sliding heating block 4 is rotatably connected to the sliding seat 24. An extrusion sheet 27 is integrally formed on the side of the clamping plate 3 facing away from the sliding seat 24. The fixed heating block 2 and the sliding heating block 4 abut against the extrusion sheet 27, allowing the two clamping plates 3 to better grip the thermoplastic composite bar and improve the stability of the fixation. A tension spring 26 is connected between the two extrusion plates 27. The tension spring 26 is used to drive the two clamping plates 3 towards each other, thereby ensuring a more stable fixation of the thermoplastic composite bar.

[0048] A water trough 12 is fixed to the fan 11. Multiple drip holes 23 are installed at the bottom of the fan 11, connected to the water trough 12. These drip holes 23 are arranged in a C-shape, allowing water in the drip holes 23 to drip onto the thermoplastic composite reinforcement. Friction grooves 25 are staggered on the inner wall of the clamping plate 3. A heat barrier 28 made of asbestos is installed on the outer wall of the clamping plate 3 to reduce heat conduction to the clamping plate 3.

[0049] The implementation principle of a rapid bending device for thermoplastic composite bars in an embodiment of the present application is as follows: during operation, the thermoplastic composite bar is inserted between two clamping plates 3 and simultaneously inserted between the clamping grooves 6, and the heating plate 22 is used to heat the thermoplastic composite bar. After heating is completed, the clamping plates 3 are driven to slide into the clamping grooves 6, and the driving member 5 is used to clamp the thermoplastic composite bar, thereby improving the stability of the thermoplastic composite bar. The staff rotates the rotating rod 7, and under the action of the bending wheel 8 and the bending block 9, the thermoplastic composite bar is bent. The locking block 13 is then used to limit the position of the thermoplastic composite bar, thereby improving the convenience of bending the thermoplastic composite bar. After bending, the switch 34 turns on the fan 11, pushing the bending block 9 to move closer to the fan 11, so that the thermoplastic composite bar can be cooled quickly, thereby improving the convenience of bending the thermoplastic composite bar.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
