[0019] The present invention will be further described in detail below with reference to embodiments:

[0020] This utility model discloses a novel bending device for the channel steel of a civil defense door frame. (Refer to...) Figure 1-4 It includes a base plate 1, three support rods 2 for support are installed at the top of the base plate 1, and a top plate 3 is installed at the top of the support rods 2. A first movable groove 4 and a disassembly groove 5 are respectively opened on one side of the base plate 1 and the top plate 3. A second movable groove 6 is opened on the other side of the base plate 1 and the top plate 3. A clamping mechanism for clamping the channel steel is installed in the first movable groove 4, and a bending mechanism for bending the channel steel is installed in the second movable groove 6.

[0021] By adopting the above technical solution, this utility model, through its clamping and bending mechanisms, facilitates the rotation of two first lead screws 10 driven by the first motor 11, thereby driving two movable blocks 7 to move in opposite directions within the first movable groove 4, thus clamping and fixing the channel steel. Subsequently, the two third lead screws 19 driven by the second motor 20 drive the bending plate 17 to move between the bottom plate 1 and the top plate 3, causing the bending plate 17 to push against the channel steel on one side of the two isolation cylinders 14, bending the channel steel. This facilitates the clamping and fixing of channel steel of various sizes, thus making it convenient to bend channel steel of various sizes.

[0022] Reference Figure 1-4 The clamping mechanism includes two movable blocks 7, both of which are movably installed in the first movable groove 4. A first limiting block 8 is fixedly installed on both sides of the two movable blocks 7. A limiting groove 9 is opened on both sides of the first movable groove 4, and the two first limiting blocks 8 are movably installed in the two limiting grooves 9 respectively.

[0023] By adopting the above technical solution, the limiting groove 9 can be set so that when the movable block 7 moves in the first movable groove 4, the first limiting block 8 is fixed in the limiting groove 9, thereby maintaining the stability of the movable block 7 during movement.

[0024] Reference Figure 1-4 Each of the two limiting grooves 9 has a first lead screw 10 rotatably installed in it. The two first lead screws 10 are threadedly connected to the first limiting block 8 respectively, and the threads on both sides of the two first lead screws 10 are set in opposite directions.

[0025] By adopting the above technical solution, and by setting the threads on both sides of the first lead screw 10 in opposite directions, it is convenient for the two first lead screws 10 to rotate and drive the two movable blocks 7 to move in opposite directions, thereby facilitating the clamping of the channel steel between the two movable blocks 7.

[0026] Reference Figure 1-4A first motor 11 is fixedly installed on one side of the base plate 1. The output shaft of the first motor 11 is driven and connected to a first lead screw 10. The other ends of the two first lead screws 10 are each equipped with a first rotating wheel 12, and the two first rotating wheels 12 are connected by a transmission belt.

[0027] By adopting the above technical solution, the first rotating wheel 12 facilitates the driving of one first lead screw 10 by the first motor 11, and the two first rotating wheels 12 can drive the two first lead screws 10 to rotate in the same direction, thereby maintaining the stability of the movement of the two movable blocks 7.

[0028] Reference Figure 1-4 Each of the two movable blocks 7 is threaded with a second lead screw 13. The top of the second lead screw 13 is threaded with an isolation cylinder 14. The top two sides of the isolation cylinder 14 are fixedly installed with second limit blocks 15. The top of the isolation cylinder 14 is matched with two second limit blocks 15 and a drive block 16 is installed.

[0029] By adopting the above technical solution, the isolation cylinder 14 can be easily rotated by rotating the drive block 16, which makes it easy to remove the isolation cylinder 14 from the second lead screw 13. This facilitates the replacement of the isolation cylinder 14 after long-term use, thereby extending the service life of the device.

[0030] Reference Figure 1-4 The bending mechanism includes a bending plate 17, which is movably installed between the bottom plate 1 and the top plate 3. A third limiting block 18 is fixedly installed on both sides of the bending plate 17. A third lead screw 19 is rotatably installed in each of the two second movable slots 6. The two third lead screws 19 are threadedly connected to the two third limiting blocks 18 respectively.

[0031] By adopting the above technical solution, the third limiting block 18 can be used to drive the bending plate 17 to move, thereby enabling the bending plate 17 to push the channel steel on one side of the two isolation cylinders 14 and bend the channel steel.

[0032] Reference Figure 1-4 A second motor 20 is fixedly installed on one side of the top plate 3. The output shaft of the second motor 20 is driven and connected to a third lead screw 19. The other ends of the two third lead screws 19 are fixedly installed with second rotating wheels 21. The two second rotating wheels 21 are connected by a transmission belt. One end of the bending plate 17 is located on the same plane as one side of the two isolation cylinders 14.

[0033] By adopting the above technical solution, the second rotating wheel 21 facilitates the driving of a third lead screw 19 by the second motor 20, thereby enabling the second rotating wheel 21 to drive another third lead screw 19 to rotate in the same direction, and thus enabling the two third limit blocks 18 to move in the same direction.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
