Description

Technical Field

[0001] This utility model relates to the field of steel bar feeding, specifically a feeding device for cold-rolled ribbed steel bar production. Background Technology

[0002] The feeding device for cold-rolled ribbed steel bar production is mainly used to feed the steel bar coils, ensuring a stable and efficient production process. It mainly provides stable support and guidance, and accurately transports the steel bar coils to the cold rolling equipment by setting up support frames, guide wheels and other structures.

[0003] In the existing technology, traditional feeding devices mainly consist of a support frame, guide wheels, and mounting components. The support frame is used to fix the entire device and bear the steel coil, ensuring its stability during the feeding process. The guide wheels are responsible for guiding the running direction of the steel bars, reducing friction and bending deformation, and ensuring smooth feeding. The mounting components are used to connect and fix other components, such as installing the guide wheels onto the support frame, and adjusting their position to accommodate steel coils of different specifications. These components work together to achieve stable conveying of the steel bars.

[0004] However, in the traditional feeding device, the guide wheel is fixed in position, and the steel bar exerts a large direct force on the guide wheel during the feeding process. If this force is too large, the guide wheel will be damaged or jammed, which is not conducive to the overall production efficiency. To solve the above-mentioned technical problems, this utility model proposes a feeding device for cold-rolled ribbed steel bar production. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a feeding device for cold-rolled ribbed steel bar production, comprising: a support frame 1, a first guide wheel 2 installed on the upper end of the support frame 1, a second guide wheel 3 installed inside the support frame 1, a feeding frame 4 installed directly below the support frame 1, the first guide wheel 2 being located directly above the feeding frame 4, and a buffer spring 5 connected below the second guide wheel 3;

[0024] In use, the steel bar coil can be placed on the feeding rack 4 below the support frame 1. Then, one end of the steel bar coil is passed through the first guide wheel 2 at the upper end of the support frame 1, and then through the second guide wheel 3 inside the support frame 1. A buffer spring 5 is installed below the second guide wheel 3. When the steel bar is fed, the steel bar will exert a large force on the second guide wheel 3. At this time, the buffer spring 5 will be stretched and contracted to absorb the excess force, thereby effectively reducing the force on the second guide wheel 3. This avoids the problem of the guide wheel being damaged or jammed due to excessive force when feeding the steel bar.

[0025] Example 2: Based on Example 1, a triangular support frame 10 is provided for stable feeding. A feeding hole 13 is formed on the upper surface of the triangular support frame 10 away from the support frame 1. A feeding frame 14 is fixedly installed directly below the feeding hole 13. The feeding frame 14 has an inverted funnel-shaped structure. Two sets of symmetrical holes are formed on the inner wall of the upper end of the feeding frame 14. A first bearing 15 is fixedly installed in the holes, and the outer ring surface of the first bearing 15 is fixedly connected to the inner wall of the hole. A first guide wheel 2 is inserted into the triangular support frame 10. Rotating rollers are fixedly installed at both ends of the first guide wheel 2, and the outer wall of the rotating rollers is fixedly connected to the inner ring surface of the first bearing 15. Feeding rack 4 Several internal reinforcing plates are fixedly installed inside. A feeding plate 6 is fixedly installed at the lower end of the feeding rack 4. A support platform 8 is fixedly installed below the feeding plate 6. Several reinforcing ribs 7 are provided between the support platform 8 and the feeding plate 6. The reinforcing ribs 7 are arranged in a linear array between the support platform 8 and the feeding plate 6. Several processing grooves 9 are opened on the side wall of the support frame 1. A feeding rack 4 is fixedly installed on one side of the side wall of the support frame 1. A triangular support frame 10 is fixedly installed on the upper end of the side wall of the support frame 1 near the feeding rack 4. An installation slot 11 is opened on the side wall of the support frame 1 directly below the triangular support frame 10. An installation plate 12 is fixedly installed on the surface of the end of the installation slot 11 away from the feeding rack 4.

[0026] To ensure stable feeding, the entire steel bar coil can be placed on the feeding rack 4. Then, one end of the steel bar coil is passed through the feeding frame 14 installed at the lower end of the triangular support frame 10. The feeding frame 14 is funnel-shaped, which can automatically center and guide the steel bar smoothly, avoiding jamming or bending caused by positional deviation. Next, it is passed through the feeding hole 13, and then the steel bar is attached to the outer surface of the first guide wheel 2. One end of the steel bar is passed through the mounting slot 11, so that the steel bar passes through the gap between the rotating frame 18 and the second guide wheel 3. Finally, one end of the steel bar is inserted into the processing chamber, making the overall feeding more stable.

[0027] Example 3: Based on Example 2, to avoid excessive force on the guide wheel from the reinforcing bars during the feeding process, a buffer spring 5 is provided. Two sets of buffer springs 5 ​​are provided, and the two sets of buffer springs 5 ​​are symmetrically fixedly installed at both ends of the support horizontal plate. The upper end of the buffer spring 5 is fixedly connected to the bottom surface of the rotating frame 18. The rotating frame 18 has an overall "U" shape structure. Rotating rollers are fixedly installed on both sides of the rotating frame 18. The outer wall of the rotating rollers is fixedly connected to the inner ring surface of the second bearing 16. The rotating frame 18 can rotate between the fixed plates. The inner wall of the end of the rotating frame 18 away from the mounting plate 12 has an opening. The inner wall of the hole is fixedly connected to a third bearing 19. A second guide wheel 3 is inserted into one end of the rotating frame 18. Rotating rollers are fixedly installed at both ends of the second guide wheel 3. The outer wall of the rotating rollers is fixedly connected to the inner ring surface of the third bearing 19. The second guide wheel 3 can rotate within the rotating frame 18. The mounting plate 12 is in the shape of an inverted "well". Fixed plates are fixedly installed at both ends of the surface of the mounting plate 12. The rotating frame 18 is inserted between the fixed plates. Holes are opened on the surface of the fixed plates. A second bearing 16 is fixedly installed on the inner wall of the holes. Two sets of symmetrical support vertical plates 17 are fixedly installed on the lower surface of the mounting plate 12.

[0028] To prevent excessive force exerted by the reinforcing bars on the second guide wheel 3, one end of a buffer spring 5 is fixedly connected to the bottom of the rotating frame 18, and the other end of the buffer spring 5 is fixedly installed on the surface of the support horizontal plate. The support vertical plate 17 supports the rotating frame 18 to keep it horizontal. During feeding, the reinforcing bars pass through the gap between the rotating frame 18 and the second guide wheel 3 and are discharged from below the second guide wheel 3. During the feeding process, the reinforcing bars will exert an upward force on the second guide wheel 3. At this time, the buffer spring 5 located below will be stretched and contracted, and its elasticity will offset part of the force, thereby effectively reducing the force borne by the second guide wheel 3. This not only protects the second guide wheel 3 from damage, but also ensures a smoother and more stable reinforcing bar conveying process.

[0029] In actual use, the steel bar coil can be placed on the feeding rack 4 below the support frame 1. Then, one end of the steel bar coil is passed through the first guide wheel 2 at the upper end of the support frame 1, and then through the second guide wheel 3 inside the support frame 1. A buffer spring 5 is installed below the second guide wheel 3. When the steel bar is fed, the steel bar will exert a large force on the second guide wheel 3. At this time, the buffer spring 5 will be stretched and contracted to absorb the excess force, thereby effectively reducing the force on the second guide wheel 3. This avoids the problem of the guide wheel being damaged or jammed due to excessive force when feeding the steel bar.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
