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 ribs. Background Art

[0002] A rapid bending device can bend profiles and quickly bend the profiles into fixed angles for more convenient use. Existing external Zhejiang devices can bend materials such as steel bars and thermoplastic composite ribs. Since the thermoplastic composite ribs are relatively hard when not heated, the thermoplastic composite ribs are usually heated and then bent with the cooperation of a rapid bending device. After the bent thermoplastic composite ribs are cooled, the profiling of the profiles can be completed.

[0003] In the prior art, a rapid bending device for thermoplastic composite ribs includes a machine base. A fixed heating block and a sliding heating block are arranged on the machine base. The fixed heating block and the sliding heating block cooperate to clamp the thermoplastic composite ribs. A driving member for driving the sliding heating block to move closer to the fixed heating block is arranged on the machine base. A bending block is arranged on the machine base. A bending groove is formed on the outer wall of the bending block. A rotating rod is rotatably connected to the bending block. A pressing wheel is rotatably connected to the rotating rod. The pressing wheel and the bending groove cooperate to bend the heated thermoplastic composite ribs. The fixed heating block and the sliding heating block are heated, and after the heating is completed, the heated part is extended. Under the action of the pressing wheel and the bending groove, and in cooperation with the fixed heating block and the sliding heating block clamping other parts of the thermoplastic composite ribs, the thermoplastic composite ribs can be quickly bent into fixed angles.

[0004] In view of the above prior art, when bending thermoplastic composite ribs, the fixed heating block and the sliding heating block need to heat the thermoplastic composite ribs at the same time and also need to fix the thermoplastic composite ribs during bending. Since the thermoplastic composite ribs need a certain time to cool after bending, if the thermoplastic composite ribs are directly taken out for cooling after bending, it is easy to affect the bending angle of the thermoplastic composite ribs. If the thermoplastic composite ribs are heated for a long time, it will affect the softness of other parts. When the thermoplastic composite ribs are taken out, it will affect the shape of other positions of the thermoplastic composite ribs, reducing the bending effect of the thermoplastic composite ribs, and there is an urgent need for improvement. Summary of the Invention

[0005] In order to enable the fixed heating block and the sliding heating block to take into account heating and clamping the thermoplastic composite ribs, reduce the influence on the thermoplastic composite ribs, and better ensure the bending effect of the thermoplastic composite ribs, the present application provides a rapid bending device for thermoplastic composite ribs.

[0006] The rapid bending device for thermoplastic composite ribs provided by the present application adopts the following technical solutions: It includes a machine base, on which a fixed heating block and a sliding heating block are arranged. A driving member is arranged on the machine base for driving the sliding heating block to approach the fixed heating block. A clamping groove for clamping a thermoplastic composite rib is formed between the fixed heating block and the sliding heating block. A heating device for heating the thermoplastic composite rib is arranged in the clamping groove. Two clamping pieces for clamping the thermoplastic composite rib are slidably connected to the machine base. When the clamping pieces slide between the fixed heating block and the sliding heating block, the two clamping pieces clamp the thermoplastic composite rib. A bending block is arranged on the machine base. A bending groove is formed on the side wall of the bending block. A rotating rod is rotatably connected to the bending block. A bending wheel is rotatably connected to the rotating rod. The side wall of the bending wheel cooperates with the bending groove to bend the thermoplastic composite rib. A fan is arranged on the machine base for accelerating the cooling of the thermoplastic composite rib.

[0007] By adopting the above technical solution, during operation, the thermoplastic composite rib is clamped by two clamping pieces, and the driving member is used to drive the sliding heating block to press against the fixed heating block, so as to achieve the purpose of clamping the thermoplastic composite rib. The heating device is used to heat the thermoplastic composite rib. After the thermoplastic composite rib is heated for a period of time, the thermoplastic composite rib becomes soft. Then the thermoplastic composite rib is taken out and the heated thermoplastic composite rib is pushed out. At the same time, the clamping pieces are inserted into the clamping groove, so as to achieve the functions of heat insulation and fixing the thermoplastic composite rib, making the thermoplastic composite rib more stably fixed. Then the rotating rod is rotated. Under the action of the bending wheel and the bending groove, the thermoplastic composite rib can be bent more conveniently. The fan is used to accelerate the cooling of the thermoplastic composite rib. After cooling for a certain time, the thermoplastic composite rib is shaped, so that the thermoplastic composite rib can be bent better. Adopting such a design can reduce the contact between the fixed heating block and the sliding heating block and other positions of the thermoplastic composite rib, enable the fixed heating block and the sliding heating block to both heat and clamp the thermoplastic composite rib, reduce the influence on the thermoplastic composite rib, and better ensure the bending effect of the thermoplastic composite rib.

The bending block is detachably installed on the sliding block. The fan is fixed at 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 piece moves towards the fan.

[0009] By adopting the above technical solution, the clamping piece and the bending block move towards the fan synchronously, so as to ensure the shaping and movement of the bent thermoplastic composite rib. The fan is used to cool the thermoplastic composite rib, which can make the thermoplastic composite rib cool down more quickly.

On the one hand, the sliding of the bending block can be guided to improve the stability of the use of the bending block. On the other hand, the heat of the fixed heating block can raise the temperature of the bending block through heat conduction by inserting the plugging rod into the fixed heating block, so that the surface temperature of the bending block can be increased, and the sudden temperature drop can be avoided when the thermoplastic composite rib is bent, so that the thermoplastic composite rib can be bent better, and the bending effect of the bending device on the thermoplastic composite rib can be ensured.

[0013] By adopting the above technical scheme, after the thermoplastic composite rib is bent, the locking block is rotated to clamp the thermoplastic composite rib into the limiting cavity, so that the thermoplastic composite rib can be locked. When the thermoplastic composite rib is relatively soft, the thermoplastic composite rib can be fixed better, and the stability of the shaping of the thermoplastic composite rib is improved.

[0014] Preferably, a pressing groove is formed in the bending block, a rotating block is rotatably connected in the pressing groove, the rotating block is composed of a limiting block and a switch block.

[0018] Preferably, the heating device includes a heating sheet fixed in the clamping groove, and a soft heat-conducting sheet is arranged on the heating sheet.
