Abstract
Description
Technical Field
[0001] This utility model relates to the field of straightening technology, and in particular to a device for straightening coiled steel bars. Background Technology
[0002] Coiled steel bars are typically manufactured in coil form with a spiral surface, requiring straightening before use. Straightened coiled steel bars have a smooth surface without localized bends or sharp turns, which facilitates subsequent processing operations such as cutting, bending, and welding, ensuring construction quality. Furthermore, straightening reduces the risk of deformation during use, improving the overall stability of the structure.
[0003] In the existing technology, before entering the straightening machine, the coiled steel bars are usually stored in a coiled form. They are relatively long and, if not fixed, are prone to swaying due to gravity or mechanical traction. This swaying not only affects the smooth entry of the coiled steel bars but also poses a significant safety hazard. Therefore, we propose a coiled steel bar straightening device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for straightening coiled steel bars.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A straightening device for coiled rebar includes a straightening machine body and a wire feeding frame. Two mounting seats are fixedly connected to the outer wall of the straightening machine body. Each mounting seat has a circular hole on its outer wall. The inner wall of the two circular holes is fixedly connected to the same wire-feeding cylinder. One end of the wire-feeding cylinder is fixedly connected to a first horn-shaped cylinder. An installation plate is fixedly connected to the outer wall of the straightening machine body. Two threaded rods are fixedly connected to the outer wall of the installation plate. The outer wall of the two threaded rods is slidably fitted with the same moving plate. The outer wall of the moving plate is provided with a cutting component. The outer wall of the moving plate is fixedly connected to a second horn-shaped cylinder.
[0007] Preferably, the cutting assembly includes an L-shaped plate, the outer wall of the movable plate is fixedly connected to the outer wall of the L-shaped plate, a cylinder is fixedly connected to the top of the L-shaped plate, a cutting blade is fixedly connected to the bottom of the cylinder output end, and a ring is fixedly connected to the outer wall of the L-shaped plate.
[0008] Preferably, the outer wall of the wire feeding frame is fitted with a coiled steel bar body.
[0009] Preferably, each of the two threaded rods has two locking caps threaded onto its outer wall, and one end of each of the four locking caps is pressed against the outer wall of the moving plate.
[0010] Preferably, the outer wall of the L-shaped plate is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the cylinder output end.
[0011] Preferably, the outer wall of the ring is slidably connected to the outer wall of the cutting blade.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] This solution uses a multi-stage guide consisting of a second horn, a ring, and a first horn, and the position of the second horn can be adjusted to increase applicability. It effectively constrains the swing amplitude of the steel bar before it enters the straightening machine, significantly reducing the initial degree of twisting. The cutting component prevents machine jamming accidents. The overall design achieves coordinated operation of the wire feeding, guiding, and straightening processes, ensuring processing safety and improving production efficiency.

[0021] Depend on Figures 1-3 As shown, a device for straightening coiled steel bars is disclosed, comprising a straightening machine body 1 and a wire feeding frame 2. The outer wall of the wire feeding frame 2 is fitted with a coiled steel bar body 3. Two mounting seats 4 are fixedly connected to the outer wall of the straightening machine body 1. The outer wall of each mounting seat 4 is provided with a round hole. The inner wall of the two round holes is fixedly connected to the same wire threading cylinder 5. The two mounting seats 4 support the wire threading cylinder 5.
[0022] One end of the threading drum 5 is fixedly connected to the first horn tube 6. The outer wall of the straightening machine body 1 is fixedly connected to the mounting plate 7. The outer wall of the mounting plate 7 is fixedly connected to two threaded rods 8. The outer wall of the two threaded rods 8 is slidably fitted with the same moving plate 9. The moving plate 9 is supported by the two threaded rods 8. The outer wall of each of the two threaded rods 8 is threaded with two locking caps 10. One end of each of the four locking caps 10 is pressed against the outer wall of the moving plate 9. Through the cooperation of the double threaded rods 8 and the locking caps 10, the moving plate 9 can move linearly to adjust the position of the second horn tube 15, which is convenient to adapt to the processing requirements of different specifications of steel bars.
[0023] The outer wall of the movable plate 9 is fixedly connected to the second horn 15. Through the first horn 6 and the second horn 15, the coiled steel bar body 3 is effectively guided to smoothly enter the straightening machine body 1, which significantly reduces the phenomenon of steel bar jamming and wear.
[0024] The second horn tube 15, the ring 12, the first horn tube 6, and the threading tube 5 are all in the same horizontal direction.
[0025] The outer wall of the movable plate 9 is provided with a cutting assembly, which includes an L-shaped plate 11. The outer wall of the movable plate 9 is fixedly connected to the outer wall of the L-shaped plate 11. A cylinder 13 is fixedly connected to the top of the L-shaped plate 11. A sliding hole is opened on the outer wall of the L-shaped plate 11. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the cylinder 13. A cutting blade 14 is fixedly connected to the bottom of the output end of the cylinder 13. A ring 12 is fixedly connected to the outer wall of the L-shaped plate 11. The outer wall of the ring 12 is slidably connected to the outer wall of the cutting blade 14. The cutting blade 14, in conjunction with the guiding structure of the L-shaped plate 11 and the ring 12, ensures a smooth and precise cutting process. The sliding cooperation between the cutting blade 14 and the ring 12 effectively avoids the deviation of the reinforcing bar during cutting.
[0026] Working principle: In use, one end of the coiled steel bar body 3 is passed through the interior of the second horn cylinder 15, the ring 12, the first horn cylinder 6, and the threading drum 5, and then enters the entry end on the right side of the straightening machine body 1. Under the traction of the straightening machine body 1 and the initial threading of the wire feeding frame 2, the coiled steel bar body 3 is unwound. During the unwinding process, the coiled steel bar is guided to move through the progressive guide channel of the second horn cylinder 15, the first horn cylinder 6, and the threading drum 5, avoiding large swings at the entrance of the straightening machine body 1 and reducing the degree of twisting. At the same time, if the coiled steel bar is twisted due to the excessive speed of the straightening machine body 1, the cylinder 13 can drive the cutting blade 14 to move downward. The cutting blade 14 moves downward to cut off the twisted part, so that the part of the coiled steel bar body 3 that has entered the straightening machine body 1 can be taken out and straightened again.
