It is commonly used in steel structure fabrication and has advantages such as low energy consumption, high efficiency, and minimal impact on material properties. However, traditionally, cold bending of U-shaped steel arches requires the use of a crane for the entire lifting process, which presents three main problems: First, it results in low precision and efficiency, as the crane needs to be constantly adjusted to match the movement of the equipment and the U-shaped steel, but it cannot be precisely positioned to follow the movement of the steel. Second, it poses safety hazards, including the risk of oblique pulling and dragging from the crane's perspective, and the risk of injury from the components during operation. Third, it requires high labor input, as in addition to the cold bending personnel, a crane operator and an overhead crane operator are needed to assist in the operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-5 ;
[0023] A U-shaped steel cold bending auxiliary fixture includes a base 1, with casters 11 installed at the bottom of the base 1 and a support mechanism 2 provided at the top of the base 1 for auxiliary support of the U-shaped steel; a fixing mechanism 3 is provided on the support mechanism 2 for auxiliary positioning of the U-shaped steel.
[0024] Support mechanism 2 includes a first support component 28, a second support component 29, and a fifth U-shaped steel 23. The first support component 28 and the second support component 29 are respectively fixedly installed on the top of the base 1. The first support component 28 and the second support component 29 are used to support the installation of the fifth U-shaped steel 23. The fifth U-shaped steel 23 is installed on the top of the first support component 28 and the second support component 29. The top of the fifth U-shaped steel 23 is used to support the U-shaped steel. The first support component 28 includes a first U-shaped steel 21 and a third U-shaped steel 22. The first U-shaped steel 21 is fixedly installed on the top of the base 1, and the third U-shaped steel 22 is slidably installed on... The first U-shaped steel 21 is fixed inside and bolted together. The first U-shaped steel 21 and the third U-shaped steel 22 are used to support the installation of the fifth U-shaped steel 23. The installation height of the third U-shaped steel 22 is adjustable, thereby adjusting the support height of the fifth U-shaped steel 23. The second support assembly 29 includes a second U-shaped steel 211 and a fourth U-shaped steel 221. The second U-shaped steel 211 is fixedly installed on the top of the base 1. The fourth U-shaped steel 221 is slidably installed inside the second U-shaped steel 211 and fixed together with bolts. The second U-shaped steel 211 and the fourth U-shaped steel 221 are used to support the installation of the fifth U-shaped steel 23. The fourth U-shaped steel 221... The installation height is adjustable, thus allowing for adjustment of the support height of the fifth U-shaped steel 23. The fifth U-shaped steel 23 is welded to the top of the third U-shaped steel 22 and the fourth U-shaped steel 221. The fifth U-shaped steel 23 is fixedly installed on the upper end of the third U-shaped steel 22 and the fourth U-shaped steel 221, with its opening facing upwards. Slots 24 are provided on the inner walls of both the third U-shaped steel 22 and the fourth U-shaped steel 221. The slots 24 are used to guide the insertion and sliding of the insert 25, thereby allowing the third U-shaped steel 22 and the fourth U-shaped steel 221 to slide smoothly and preventing them from interfering with the first U-shaped steel 221 during sliding. 1. The second U-shaped steel 211 is detached to facilitate the installation of bolts to fix the third U-shaped steel 22 and the fourth U-shaped steel 221 after sliding. T-shaped inserts 25 are welded to the inner sides of the first U-shaped steel 21 and the second U-shaped steel 211. The inserts 25 are slidably inserted into the slots 24. First connecting holes 26 are opened on both sides of the first U-shaped steel 21 and the second U-shaped steel 211. Second connecting holes 27 are opened on both sides of the third U-shaped steel 22 and the fourth U-shaped steel 221. After the first connecting holes 26 and the second connecting holes 27 are aligned, bolts are installed to fix the position of the third U-shaped steel 22 and the fourth U-shaped steel 221 after height adjustment.
[0025] Furthermore, the fixing mechanism 3 includes a welded pipe 31, a U-shaped rod 32, and a nut 33. The welded pipe 31 is welded to the side wall of the fifth U-shaped steel 23, and the welded pipe 31 is used to guide the insertion of the U-shaped rod 32, such as... Figure 3As shown, after the U-shaped steel arch frame is placed on top of the fifth U-shaped steel 23, the U-shaped rod 32 is inserted into the welded pipe 31, and then nuts 33 are threaded on both ends of the U-shaped rod 32 to position the fifth U-shaped steel 23, thereby stably supporting the U-shaped steel arch frame on the fifth U-shaped steel 23 and preventing the U-shaped steel arch frame from tilting during the subsequent cold bending process.
[0026] The working principle of this utility model is as follows: Simultaneously, the third U-shaped steel 22 and the fourth U-shaped steel 221 slide to adjust the height of the fifth U-shaped steel 23. Then, the third U-shaped steel 22 is bolted to the first U-shaped steel 21, and the fourth U-shaped steel 221 is bolted to the second U-shaped steel 211. One end of the hoisted U-shaped steel arch material is placed on top of the fifth U-shaped steel 23, and the other end is assembled into the cold bending machine. Then, the crane and the hoisting personnel withdraw, and the U-shaped rod 32 is inserted into the welded pipe 31. Nuts 33 are then threaded onto both ends of the U-shaped rod 32 and tightened. The fifth U-shaped steel 23 is positioned to stably support the U-shaped steel arch frame, preventing it from tilting during subsequent cold bending. The cold bending equipment is used to process the U-shaped steel arch frame material. The U-shaped steel arch frame material is supported by the U-shaped steel cold bending auxiliary fixture. The bottom of the device is equipped with casters 11 for support and movement. The auxiliary fixture as a whole is adjusted in position by the casters 11 and can move in any direction. The direction of movement of the U-shaped steel arch frame material and the auxiliary fixture depends on the force exerted by the auxiliary fixture during cold bending. After bending is completed, the U-shaped rod 32 is released, and the U-shaped steel arch frame material is lifted away.
[0027] In summary, by setting up auxiliary tooling for cold bending of U-shaped steel, the continuous lifting operation of the crane during the operation can be eliminated, reducing manual labor input. The components can be automatically fed and adjusted, eliminating the safety hazards of the crane pulling at an angle and the components breaking off and injuring people during the operation, and improving the overall operation efficiency.
[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
