[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-4 As shown, this utility model provides a quick bending device for angle steel, including an operating table 1. A support plate 2 is fixedly connected to the top of the operating table 1. Two fixing rods 3 are fixedly connected to the top of the support plate 2. Static molds 4 are movably fitted on the outer walls of the two fixing rods 3. First fixing seats 5 are fixedly connected to one side of the outer walls of the two static molds 4. Connecting rods 6 are movably fitted on the outer walls of the two first fixing seats 5. Second fixing seats 7 are movably inserted into the inner walls of the two connecting rods 6. Two bearing seats 8 are fixedly installed on the top of the operating table 1. A bidirectional lead screw 9 is fixedly inserted between the interiors of the two bearing seats 8. A drive motor 10 is fixedly connected to one side of the outer wall of the bidirectional lead screw 9. Two threaded blocks 11 are threadedly connected to the outer walls of the bidirectional lead screw 9. The outer walls of the two second fixing seats 7 are fixedly connected to the outer walls of the two threaded blocks 11.

[0026] The overall effect of Embodiment 1 is as follows: First, according to the specific angle that the angle steel needs to be bent, the drive motor 10 is started. The output end of the drive motor 10 drives the bidirectional lead screw 9 to rotate. Since the threads on both sides of the bidirectional lead screw 9 are opposite, and the outer wall of the bidirectional lead screw 9 is threadedly connected to the inner wall of the two threaded blocks 11, the rotation of the bidirectional lead screw 9 will cause the two threaded blocks 11 to move synchronously in opposite directions. The movement of these two threaded blocks 11 will further change the angle of the two connecting rods 6, thereby pushing the two stationary molds 4 to rotate about the corresponding fixed rod 3 as the axis. This rotation will cause the relative angle between the two stationary molds 4 to change, thereby changing the angle of the bending groove formed between them. When the angle steel is placed between the two stationary molds 4 and bent, its bending angle will accurately meet the preset value, thereby significantly improving the flexibility of the device. In addition, with this bending method, there is no need to frequently change the stationary molds 4, thereby reducing processing costs and time costs and improving production efficiency.

[0027] Example 2, as Figures 2-4 As shown, two slide rails 12 are fixedly installed on the top of the operating table 1. A push plate 13 is movably sleeved between the outer walls of the two slide rails 12. A hydraulic cylinder 14 is fixedly connected to one side of the outer wall of the push plate 13. A slot 15 is opened on the other side of the outer wall of the push plate 13. A locking block 16 is movably inserted into the inner wall of the slot 15. A moving mold 17 is fixedly connected to one side of the outer wall of the locking block 16. A limit groove 18 is opened on the top of the locking block 16. A limit block 19 is movably inserted into the inner wall of the limit groove 18. A pull plate 20 is fixedly connected to the top of the limit block 19. Two return springs 21 are fixedly connected to the bottom of the pull plate 20.

[0028] The overall effect of Embodiment 2 is that when the moving mold 17 needs to be replaced or repaired due to wear or damage caused by long-term use, the first operation is to pull the pull plate 20. The movement of the pull plate 20 will drive the limit block 19 to move upward until the limit block 19 is completely disengaged from the limit groove 18, thereby releasing the fixing effect on the locking block 16, so that the moving mold 17 can be easily removed from the device. During this process, the movement of the pull plate 20 will also stretch the two return springs 21 at the same time, storing potential energy for subsequent reset operations. When the moving mold 17 is replaced or repaired and needs to be reinstalled, simply align the locking block 16 on one side of the outer wall of the moving mold 17 and insert it into the slot 15. Then, using the elastic potential energy stored in the two return springs 21, push the limit block 19 to re-lock into the limit groove 18, thereby realizing the quick and stable reinstallation of the moving mold 17. In this way, not only is the disassembly and assembly process of the moving mold 17 simplified, but the maintenance efficiency and flexibility of the device are also improved, thereby ensuring the continuity and stability of the production process.

[0029] Working principle: in use, first, according to the angle of the angle steel required to bend the specific angle, start the driving motor 10, the output end of the driving motor 10 drives the bidirectional screw rod 9 to rotate, because the two sides of the bidirectional screw rod 9 adopt opposite thread design, and its outer wall is connected with two threaded blocks 11, therefore the rotation of the bidirectional screw rod 9 can ensure that the two threaded blocks 11 move synchronously and accurately in opposite directions, the movement of the two threaded blocks 11 further through the mechanical linkage of connecting rod 6, two static dies 4 are respectively adjusted in angle with corresponding fixed rod 3 as the rotation axis, so as to realize the flexible adjustment of the relative angle between the two static dies 4, to adapt to the demand of different bending angle, then, by starting the hydraulic cylinder 14, its telescopic end can smoothly and powerfully drive the push plate 13 and the movable die 17 to move, so as to accurately bend the angle steel, when the movable die 17 needs to be replaced or repaired due to wear or damage caused by long-term use, first, pull the pull plate 20, the pull plate 20 will drive the limiting block 19 to move upwards, until the limiting block 19 is completely separated from the limiting groove 18, so as to release the fixing effect of the clamping block 16, at this time, the movable die 17 can be easily disassembled from the device, convenient for replacement or repair operation, and the movement of the pull plate 20 also stretches two return springs 21, reserves necessary elastic potential energy for subsequent reset operation, when the movable die 17 is replaced or repaired, only need to insert the clamping block 16 of the movable die 17 into the clamping groove 15, then use the elastic potential energy reserved by the two return springs 21, push the limiting block 19 to reinsert into the limiting groove 18, so as to realize the quick and stable reinstallation of the movable die 17.

[0030] The above is only the preferred embodiment of the present application, not other forms of the present application, any skilled in the art may use the above disclosed technical content to change or modify equivalent examples applied to other fields, but any simple modification, equivalent change and modification of the above examples according to the technical essence of the present application still belongs to the protection scope of the present application technical scheme.
