Description

Technical Field

[0001] This utility model relates to the field of steel bar processing equipment, and in particular to an environmentally friendly steel bar recycling and reprocessing equipment. Background Technology

[0002] With the rapid development of the construction industry, reinforced concrete structures are widely used in various projects, resulting in a large amount of scrap steel bars. As an important building material, the recycling of steel bars has significant environmental and economic benefits: on the one hand, recycling steel bars can reduce dependence on primary mineral resources, lower energy consumption and carbon dioxide emissions, and implement the concept of green and sustainable development; on the other hand, the reprocessing of scrap steel bars can reduce construction costs, improve resource utilization, and reduce environmental pollution from waste. During the steel bar recycling process, scrap steel bars often have problems such as bending and deformation, requiring straightening before reuse.

[0003] In existing technologies, mechanical reaction devices are commonly used to straighten steel bars by applying a reverse force to the bent parts. However, this method has obvious drawbacks when dealing with steel bars with excessively large bending angles: due to the large plastic deformation of steel bars, directly applying high-strength reaction forces will cause the equipment to bear extremely high stress and impact loads, which can easily lead to premature wear, fatigue fracture or deformation of the straightening components, thereby reducing the service life of the equipment and increasing maintenance costs and downtime. Utility Model Content

[0004] To address the aforementioned deficiencies in the existing technology, this utility model provides an environmentally friendly steel bar recycling and reprocessing equipment that can efficiently and with low damage process steel bars with excessive bending angles, aiming to improve the durability of the equipment and the recycling efficiency of steel bars.

[0005] The technical solution of this utility model is as follows: an environmentally friendly steel bar recycling and reprocessing equipment, comprising: a frame shell; a first motor fixedly connected inside the frame shell; a first gear fixedly connected to the output end of the first motor; an installation cylinder rotatably connected to the middle of the frame shell; a first gear ring fixedly connected to the circumferential surface of the installation cylinder, which meshes with the first gear, so that the first motor provides driving force for the rotation of the installation cylinder; and straightening shafts arranged around the circumference of the installation cylinder, with at least three shafts arranged in each ring, and at least three rings in total; along the axial direction of the installation cylinder from front to back, the diameter of the circle enclosed by each ring of straightening shafts decreases sequentially, wherein the diameter of the circle enclosed by the last ring of straightening shafts matches the axial section diameter of the steel bar to be processed.

[0006] As a preferred embodiment of this utility model, the straightening shaft bracket is slidably connected to the mounting cylinder; it also includes: a spring sleeved on the straightening shaft bracket, with its two ends fixedly connected to the mounting cylinder and the straightening shaft bracket respectively; a second motor fixedly connected inside the mounting cylinder, the output end of the second motor being coaxially fixed to the connecting shaft; a second gear fixedly connected to the connecting shaft inside the mounting cylinder, the number and position of which match the number and position of the straightening shaft brackets; a second gear ring rotatably connected to the mounting cylinder, the number and position of which match the number and position of the straightening shaft brackets, each second gear ring meshing with the corresponding second gear; an inclined surface fixedly connected to each second gear ring, the number and circumferential position of the inclined surface of each second gear ring matching the number and position of the ring straightening shaft brackets at the corresponding position of the second gear ring; and a slot provided at the tail of each straightening shaft bracket, which slides with the corresponding second gear ring through the slot and maintains contact with the inclined surface on the corresponding second gear ring.

[0007] As a preferred technical solution of this utility model, it also includes: a cleaning brush roller rotatably connected inside the frame shell, used to remove rust spots attached to the surface of the reinforcing bars.

[0008] As a preferred technical solution of this utility model, it further includes: a cleaning frame fixedly connected inside the frame shell, which is inserted between the bristles of the cleaning brush roller.

[0009] As a preferred technical solution of this utility model, it also includes: a collection box slidably connected to the bottom of the frame shell, used to receive and collect the rust that falls off during the cleaning process.

[0010] As a preferred technical solution of this utility model, it also includes: a fan fixedly connected to the top of the frame shell, with its air outlet facing downward.

[0011] Beneficial effects: This utility model disperses the straightening force through a dynamic, multi-point, and gradual impact method, avoiding the problem of strong and continuous static reaction force between the straightening shaft and the reinforcing bar. This allows the impact force to be reasonably dispersed and absorbed, significantly reducing premature wear of the straightening components due to excessive stress, thus improving the overall durability of this utility model. The gradually narrowing straightening channel design can adapt to reinforcing bars with different degrees of curvature, and the straightening force is gentler, which can more efficiently eliminate residual stress inside the reinforcing bar. This ensures the straightening effect while minimizing damage to the reinforcing bar material, protecting the original mechanical properties of the reinforcing bar. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0017] Example: An environmentally friendly steel bar recycling and reprocessing equipment, see reference. Figures 1-3 The system includes: a frame housing 1; a first motor 2 fixedly installed at the bottom of the frame housing 1; a first gear 3 fixedly installed on the output end of the first motor 2; a mounting cylinder 5 rotatably installed in the middle of the frame housing 1; a first gear ring 4 fixedly installed on the circumferential surface of the mounting cylinder 5, which meshes with the first gear 3, so that the first motor 2 provides driving force for the rotation of the mounting cylinder 5; a straightening shaft bracket 6 arranged around the circumference of the mounting cylinder 5, which has six rings per ring, for a total of four rings; along the axial direction of the mounting cylinder 5 from front to back, the circular diameter of each ring of the straightening shaft bracket 6 decreases sequentially, wherein the circular diameter of the last ring of the straightening shaft bracket 6 matches the axial section diameter of the steel bar to be processed.

[0018] After the first motor 2 is started, power is transmitted to the mounting cylinder 5 via the first gear 3 and the first gear ring 4, driving the mounting cylinder 5 and the straightening shaft 6 on it to rotate. The bent steel bar to be processed is fed into the mounting cylinder 5 at a uniform and stable speed. At this time, because the diameter of the circle formed by the four straightening shafts 6 decreases from front to back, it will form a gradually narrowing straightening channel. Therefore, during the feeding process of the steel bar from front to back, its bent part will first come into contact with the high-speed rotating straightening shaft 6. The high-speed rotating straightening shaft 6 will generate a collision force on the bent part of the steel bar. As the steel bar is continuously delivered, the direction of the force exerted by the straightening shaft 6 on the steel bar will gradually move closer to the original axis of the steel bar, and finally achieve progressive straightening. This multi-point, progressive straightening mode can decompose the plastic bending deformation of the steel bar into multiple small and dispersed micro-straightening processes, and gradually eliminate the bending deformation of the steel bar through step-by-step correction. When the steel bar passes through the last straightening shaft 6 that is precisely matched with its own diameter, the shaping calibration will be completed and the output will be stable.

[0019] Therefore, this equipment disperses the straightening force through dynamic, multi-point, and gradual impact, avoiding the problem of strong and continuous static reaction force between the straightening shaft 6 and the reinforcing bar. This allows the impact force to be reasonably dispersed and absorbed, significantly reducing premature wear of the straightening components due to excessive stress and improving the overall durability of the equipment. The tapered straightening channel design can adapt to reinforcing bars with different degrees of curvature, and the straightening force is gentler, which can more efficiently eliminate residual stress inside the reinforcing bar. This ensures the straightening effect while minimizing damage to the reinforcing bar material and protecting the original mechanical properties of the reinforcing bar.

[0020] See Figure 2 and Figure 3 The system includes: a straightening shaft bracket 6 slidably mounted on the mounting cylinder 5; a spring 7 sleeved on the straightening shaft bracket 6, with its two ends fixedly connected to the mounting cylinder 5 and the straightening shaft bracket 6 respectively; a second motor 8 fixedly mounted inside the mounting cylinder 5; a connecting shaft also provided inside the mounting cylinder 5, with the output end of the second motor 8 coaxially fixed to the connecting shaft; four second gears 9 fixedly mounted on the connecting shaft inside the mounting cylinder 5, their positions corresponding to the four rings of straightening shaft bracket 6; four second gear rings 10 rotatably mounted on the mounting cylinder 5, each corresponding to the position of a ring of straightening shaft bracket 6, with each second gear ring 10 meshing with the corresponding second gear 9; inclined surfaces 11 fixedly mounted on each second gear ring 10, the number and circumferential position of the inclined surfaces 11 on each second gear ring 10 matching the number and position of the rings of straightening shaft bracket 6 at the corresponding position of the second gear ring 10; and a slot at the tail of each straightening shaft bracket 6, through which it slides into the corresponding second gear ring 10 and maintains contact with the inclined surface 11 on the corresponding second gear ring 10.

[0021] The second motor 8 is started, and the power is transmitted to the inclined plane 11 through the second gear 9 and the second gear ring 10. This controls the displacement of the inclined plane 11 relative to the straightening shaft 6. The inclined plane 11 then exerts a thrust on the straightening shaft 6 along its installation direction through contact with the tail of the straightening shaft 6, causing the straightening shaft 6 to slide synchronously toward the center of the mounting cylinder 5, thus changing the size of the circle enclosed by the straightening shaft 6. By adjusting the size of the circle enclosed by the straightening shaft 6 located in the last ring layer to accurately match the actual diameter of the steel bar to be processed, the adaptability of this equipment to steel bars of different specifications is improved, effectively expanding the versatility of this equipment, and ensuring that steel bars of all sizes can obtain stable and qualified straightening results during processing.

[0022] See Figures 1-3The equipment also includes: a cleaning brush roller 12 rotatably installed inside the frame 1, made of a metal material with a hardness higher than that of the reinforcing steel, and arranged on the rear side of the straightening shaft frame 6, used to remove rust spots attached to the surface of the reinforcing steel. Setting the cleaning process after straightening helps the cleaning brush roller 12 to make full contact with the reinforcing steel, thereby improving the cleaning effect. A drive component is provided inside the frame 1 to drive the cleaning brush roller 12 to rotate at high speed; a cleaning frame 13 fixedly installed inside the frame 1, which is inserted between the bristles of the cleaning brush roller 12. When the cleaning brush roller 12 rotates, it moves relative to the cleaning frame 13 to effectively remove the impurities accumulated between the bristles of the cleaning brush roller 12, which helps to maintain the cleaning ability of the cleaning brush roller 12 and extend its effective service life; a collection box 14 slidably installed at the bottom of the frame 1, used to receive and concentrate the rust that falls off during the cleaning process, which facilitates unified cleaning and keeps the operating environment of the equipment clean; and a fan 15 fixedly installed at the top of the frame 1, with its air outlet facing downwards, which can help enhance the peeling effect of rust spots from the surface of the reinforcing steel and further improve the overall quality of the reinforcing steel treatment.
