Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a protective shaping tool for coiled steel. Background Technology

[0002] The coiled steel protection and shaping tool is a device specifically designed for the processing of reinforcing bars. It is used to protect and shape coiled steel. It mainly consists of a frame structure and auxiliary components, possessing a certain strength and stability. During the straightening and transportation of coiled steel, through its specific shape design and internal structure, it guides the coiled steel into the subsequent processing equipment in a stable and orderly manner. This ensures that the coiled steel maintains the correct orientation during the processing flow, providing a good foundation for straightening and other processing steps. It comprehensively protects the safety and quality of the coiled steel processing, significantly improving the overall efficiency and quality of reinforcing bar processing.

[0003] Currently, Chinese utility model patent CN215845409U discloses a standardized protective device for straightening coiled steel bars. It includes a large-end support frame, a small-end support frame, a large upright ring welded to the large-end support frame, a small ring welded to the small-end support frame parallel to the large ring, a set of longitudinal rods evenly distributed around the large and small rings and welded to both ends respectively, and a stiffening hoop welded to the inner or outer perimeter of the longitudinal rods and located between the large and small rings. The large ring, small ring, and longitudinal rods form a conical cage. This utility model has a simple structure, is easy to use, and prevents the coiled steel bars from tangling or being thrown out and causing injury during forward pulling within the conical cage, ensuring safety and reliability.

[0004] Even when the coiled steel passes through the protective shaping tool, it may still exhibit irregular swaying. This interferes with the precise entry of the coiled steel into the straightening machine, reducing straightening efficiency and accuracy. This can lead to quality defects such as bending and twisting in the straightened steel bars. Furthermore, the violent swaying may impact the inner wall of the protective shaping tool, accelerating tool wear, shortening its service life, and increasing equipment maintenance costs. The swaying coiled steel also poses a risk of derailment and ejection, significantly threatening the personal safety of surrounding operators. This greatly restricts the efficient and safe processing of steel bars. In addition, the coiled steel may accumulate dust before entering the straightening machine. If this dust is not cleaned, it will increase friction between components, accelerating the wear of rollers and cutters, reducing their service life, increasing the cost of equipment maintenance and replacement, and easily causing scratches and other defects on the surface of the coiled steel, affecting its appearance quality. Utility Model Content

[0005] The purpose of this utility model is to provide a protective shaping tool for coiled steel, which has the advantages of reducing the swaying of the coiled steel when passing through the protective shaping tool and cleaning the dust on the surface of the coiled steel.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel coil protective shaping tool, including a first support and a second support, a first ring welded to the inner side of the first support, a second ring welded to the inner side of the second support, longitudinal rods welded to the surfaces of the first and second rings, and the longitudinal rods are distributed in a ring on the surfaces of the first and second rings, a stiffening hoop is provided at intervals between the first and second rings, and the surface of the stiffening hoop is welded to the longitudinal rod, a connecting plate is symmetrically welded to the surface of each stiffening hoop, a rack is slidably connected to the middle of the top of the connecting plate, a vertical plate is welded to the left side of the top of the connecting plate, a rotating rod is rotatably connected to the right side of the vertical plate through a bearing, a gear meshing with the rack is sleeved on the surface of the rotating rod, a handle is fixedly connected to the other end of the rotating rod, a rectangular groove is opened on the surface of the stiffening hoop, a push plate is welded to the side of the rack near the rectangular groove, a connecting rod is provided on the side of the push plate away from the rectangular groove, a roller is rotatably connected between the two connecting rods, and a dust removal mechanism is provided at intervals on the surface of one of the longitudinal rods.

[0007] The above technical solution reduces irregular swaying of the coiled steel when passing through the protective tool, allowing the coiled steel to enter the straightening machine more accurately. It avoids injury to workers caused by the swaying of the coiled steel when passing through the protective tool, and can adapt to coiled steel of different sizes. At the same time, it can remove dust from the surface of the coiled steel, reducing the impact of the coiled steel on the internal components of the straightening machine, increasing the service life of the components, and improving processing efficiency.

[0008] The present invention is further configured such that the dust removal mechanism includes a fixed block, the interior of the fixed block is welded to the surface of the longitudinal rod, an electric rod is fixedly connected to the bottom of the fixed block, a threaded rotating rod is fixedly connected to the telescopic end of the electric rod, and a brush is provided at the bottom of the threaded rotating rod.

[0009] The above technical solution, by setting a fixed block, an electric rod and a brush, can adjust the distance between the brush and the coiled steel, thereby adapting to coiled steel of different sizes and removing dust from the surface of the coiled steel. This reduces damage to internal components after the coiled steel enters the straightening machine and extends the service life of the internal components of the straightening machine.

[0010] The present invention is further configured such that a first threaded hole is provided at the top of the brush, and the surface of the threaded rotating rod is threadedly connected to the first threaded hole.

[0011] The above technical solution facilitates the replacement and installation of the brush by setting a threaded rotating rod and a first threaded hole.

[0012] The present invention is further configured such that a groove is provided in the middle of the top of the connecting plate, and the inner wall of the groove is slidably connected to the bottom of the rack.

[0013] By adopting the above technical solution, the movement of the rack can be made horizontal by setting the slide groove, which can prevent the rack from deviating from the direction and also reduce friction, thus facilitating the movement of the rack.

[0014] The present invention is further configured such that a support plate is welded to the right side of the top of the connecting plate, a limiting plate is welded to the top of the support plate, a plurality of limiting holes are provided on the surface of the limiting plate, a first spring is fixedly connected to the right side of the handle, and a pull rod is fixedly connected to the other end of the first spring, the pull rod being used in conjunction with the limiting holes.

[0015] By adopting the above technical solution, the rack can be limited by setting a support plate, a limiting plate, a limiting hole, a first spring, and a pull rod, thus preventing the rack from moving on its own.

[0016] The present invention is further configured such that a second spring is fixedly connected to the side of the push plate away from the rectangular groove, the other end of the second spring is fixedly connected to the side of the connecting rod near the push plate, and an anti-slip pad is adhered to the surface of the roller.

[0017] The above technical solution is adopted as follows: by setting a second spring, the distance between the coiled steel and the roller can be finely adjusted according to its own size when passing through the protective shaping tool, so as to better contact the roller with the surface of the coiled steel. By setting an anti-slip pad, the contact between the coiled steel and the roller can be better, and the impact of the coiled steel on the roller can be reduced, thus avoiding frequent replacement of the roller.

[0018] The present invention is further configured such that a second threaded hole is provided at the bottom of the first bracket and the second bracket, and a third threaded hole is provided on the left side of the second bracket.

[0019] By adopting the above technical solution, the second and third threaded holes can be set to facilitate the fixation of the entire protective shaping tool, thus avoiding instability of the protective shaping tool during operation.

[0020] The present invention is further configured such that the first support, the second support, and the longitudinal rod together form a conical grid frame, and the inner diameter of the first ring is larger than the inner diameter of the second ring.

[0021] The above technical solution utilizes a tapered space frame of a specific shape to facilitate the protection of the coiled steel.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. Before use, the operator pulls the lever according to the size of the coiled steel, pulls the handle out of the limiting hole, and rotates the handle to drive the gear to rotate. The rotation of the gear will drive the rack to move in the slide groove. At the same time as the rack moves, the push plate and roller will move together. After moving to the appropriate position, the handle is released, and the lever will enter the limiting hole under the action of the first spring to limit the rack. This can reduce the irregular swing of the coiled steel when passing through the protective tool, so that the coiled steel can enter the straightening machine more accurately and avoid injury to the operator caused by the swing of the coiled steel when passing through the protective tool. It can also adapt to coiled steel of different sizes.

[0024] 2. In this invention, when the coiled steel passes the protective tool, the electric rod is activated. The telescopic end of the electric rod drives the brush to descend and contact the surface of the coiled steel. The brush removes dust from the surface of the coiled steel. However, prolonged use of the brush can easily cause damage. To replace the brush, simply rotate it to remove it, and rotate it in the opposite direction to install a new brush. This method effectively removes dust from the surface of the coiled steel, reduces the impact of the coiled steel on the internal components of the straightening machine, increases the service life of the components, and improves processing efficiency.

A rectangular groove 13 is opened on the surface of the stiffening hoop 6. The rack 8 is close to the rectangular groove 12. A push plate 14 is welded to one side of the rectangular groove 13. A connecting rod 15 is provided on the side of the push plate 14 away from the rectangular groove 13. A roller 16 is rotatably connected between the two connecting rods 15. Before use, the operator pulls the pull rod 24 according to the size of the coiled steel and pulls the handle 12 out of the limiting hole 22. Turning the handle 12 drives the gear 11 to rotate. The rotation of the gear 11 will drive the rack 8 to move in the slide groove 19. When the rack 8 moves, the push plate 14 and the roller 16 will move together. After moving to the appropriate position, the handle 12 is released. The pull rod 24 will enter the limiting hole 22 under the action of the first spring 23 to limit the rack 8.

After moving to the appropriate position, release the handle 12, and the lever 24 will enter the limiting hole 22 under the action of the first spring 23 to limit the rack 8.

[0039] Example 2:

[0040] refer to Figure 1 and Figure 2 A protective and shaping tool for coiled steel includes a longitudinal rod 5 with a dust removal mechanism 17 spaced along its surface. When the coiled steel passes through the protective tool, an electric rod 1702 is activated. The telescopic end of the electric rod 1702 drives a brush 1704 to descend and contact the surface of the coiled steel. Dust on the surface of the coiled steel is removed by the bottom of the brush 1704. Prolonged use of the brush 1704 can easily cause damage. To replace the brush 1704, simply rotate it to remove it, and rotate it in the opposite direction to install a new brush. This method effectively removes dust from the surface of the coiled steel, reducing the impact of the coiled steel on the internal components of the straightening machine, increasing the service life of the components, and improving processing efficiency.

An electric rod 1702 is fixedly connected to the bottom of the fixed block 1701. A threaded rotating rod 1703 is fixedly connected to the telescopic end of the electric rod 1702. A brush 1704 is provided at the bottom of the threaded rotating rod 1703. By setting the fixed block 1701, the electric rod 1702 and the brush 1704, the distance between the brush 1704 and the coiled steel can be adjusted, thereby adapting to coiled steel of different sizes and removing dust from the surface of the coiled steel. This reduces the damage to the internal parts of the straightening machine after the coiled steel enters the straightening machine and extends the service life of the internal parts of the straightening machine.

[0042] refer to Figure 2 The brush 1704 has a first threaded hole 18 at its top, and the surface of the threaded rod 1703 is threadedly connected to the first threaded hole 18. By setting the threaded rod 1703 and the first threaded hole 18, it is easy to replace and install the brush 1704.

[0043] Brief description of usage: When the coiled steel passes the protective tool, start the electric rod 1702. The telescopic end of the electric rod 1702 drives the brush 1704 to descend and contact the surface of the coiled steel. The dust on the surface of the coiled steel is removed by the bottom of the brush 1704. With prolonged use, the brush 1704 is prone to damage. When replacing the brush 1704, rotate the brush 1704 to remove it, and rotate the brush 1704 in the opposite direction to install the new brush 1704.
