Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to an automatic centering and straightening device for round steel billets. Background Technology

[0002] Round steel billets are a type of steel product with a circular cross-section. They are semi-finished products obtained by casting or rolling molten steel produced in a steelmaking furnace. They are widely used in many fields such as construction, machinery manufacturing, automobile manufacturing, shipbuilding, and petrochemicals. As a raw material, the quality of round steel billets directly affects the performance and quality of subsequent processed products.

[0003] However, during the traditional production process of round steel billets, factors such as temperature, material, and processing technology can cause bending, which not only affects the appearance quality of the billets but, more importantly, reduces their mechanical and processing properties. Currently, the straightening process for round steel billets is mostly semi-automated. Due to the large size of the billets, manual operation of the machinery is required for loading and unloading, which involves tedious adjustments and reduces production efficiency. Furthermore, the straightening clamps cannot be replaced with those for different billet sizes, making it difficult to achieve optimal contact between the billet and its lower part when straightening billets of different diameters. This results in poor stability and suboptimal straightening results. Utility Model Content

[0004] To address the issues that round steel billet straightening is mostly semi-automatic, with cumbersome loading and unloading processes and inconvenient straightening clamps that cannot be easily replaced according to the diameter of the round steel billet, the purpose of this utility model is to provide an automatic centering and straightening device for round steel billets.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an automatic centering and straightening device for round steel billets, comprising a base plate, a frame fixedly installed on one side of the top of the base plate, two symmetrically distributed movable grippers slidably installed on the upper surface of the middle part of the frame, two symmetrically distributed support frames fixedly installed on one side of the top of the base plate, a first synchronous wheel rotatably installed in the middle of each of the two support frames, a second synchronous wheel rotatably installed on the upper part of each of the two support frames, a synchronous belt sleeved on the middle of the first and second synchronous wheels, a cam fixedly installed on one side of each of the multiple second synchronous wheels, a movable frame movably installed on one side of each of the two sets of cams, a rotating shaft fixedly installed in the middle of the two first synchronous wheels, a drive assembly provided on one side of the rotating shaft, a limit plate fixedly installed on the top of each of the two support frames, four evenly distributed support legs fixedly installed on one side of the top of the base plate, a placement plate fixedly installed on the top of the four support legs, two symmetrically distributed limit frames fixedly installed on the top of the base plate, and a straightening device fixedly installed on the upper surface of the middle part of the frame.

[0006] Preferably, a movable plate is slidably installed in the middle of the base plate, and two symmetrically distributed support rods are fixedly installed at the top of the movable plate. Each support rod has a retainer at its top, and two symmetrically distributed limiting blocks are fixedly installed at the bottom of each retainer. Bolts are slidably inserted through the upper part of each support rod, and nuts that cooperate with each other are threaded on one side of each bolt.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application can drive the moving frame to move through the first motor, pick up the round steel billets placed on the placement plate one by one, and then clamp and load them through the moving gripper, thereby solving the problem of difficulty in loading round steel billets that need to be corrected in the existing equipment, and greatly improving the work efficiency and convenience of operation.

[0009] 2. This application enables better contact and positioning of the lower part of the billet when straightening round steel billets of different thicknesses by replacing the card holder. This not only improves the stability of the straightening process but also enhances the straightening efficiency and quality, ensuring that each straightening operation achieves the best results.

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.

[0018] Example: Figure 1-5 As shown, this utility model provides an automatic centering and straightening device for round steel billets, including a base plate 1. A frame 2 is fixedly installed on one side of the top of the base plate 1. Two symmetrically distributed movable grippers 22 are slidably installed on the upper surface of the middle part of the frame 2. Two symmetrically distributed support frames 31 are fixedly installed on one side of the top of the base plate 1. A first synchronous wheel 32 is rotatably installed in the middle of each of the two support frames 31. A second synchronous wheel 33 is rotatably installed on the upper part of each of the two support frames 31. A synchronous belt 34 is sleeved on the middle of the first synchronous wheel 32 and the second synchronous wheel 33. A cam 36 is fixedly installed on one side of each of the multiple second synchronous wheels 33. One side of each of the two sets of cams 36 is movably mounted on... The frame is equipped with a movable frame 37. A rotating shaft 35 is fixedly installed in the middle of the two first synchronous wheels 32. A drive assembly is provided on one side of the rotating shaft 35. Limit plates 38 are fixedly installed at the top of the two support frames 31. Four evenly distributed support legs 4 are fixedly installed on one side of the top of the base plate 1. A placement plate 41 is fixedly installed at the top of the four support legs 4. The placement plate 41 is used to place the round steel billet that needs to be straightened. At the same time, the placement plate 41 is inclined to facilitate the removal of the round steel billet by the material handling equipment. Two symmetrically distributed limit frames 51 are fixedly installed at the top of the base plate 1. A straightening device 5 is fixedly installed on the upper surface of the middle part of the frame 2.

[0019] A movable plate 11 is slidably installed in the middle of the base plate 1. Two symmetrically distributed support rods 12 are fixedly installed at the top of the movable plate 11. Each of the two support rods 12 has a retainer 13 at its top. Each of the two retainers 13 has two symmetrically distributed limit blocks 14 fixedly installed at its bottom. Each of the two support rods 12 has a bolt 17 slidably passing through its upper part. Each of the two bolts 17 has a nut 18 threaded on one side for mutual use.

[0020] The drive assembly includes a first motor 3, which is fixedly mounted on the lower side of the frame 2, and one end of the rotating shaft 35 is fixedly mounted on the drive end of the first motor 3.

[0021] Two inclined limiting rods 42 are fixedly installed on the top of the placement plate 41. By setting the limiting rods 42, the round steel billet placed on the placement plate 41 can be limited, and the inclined setting ensures that the round steel billet can be smoothly removed from the top of the placement plate 41 by the moving frame 37.

[0022] Two symmetrically distributed grooves 43 are provided on one side of the placement plate 41. By setting the grooves 43, the moving frame 37 moves the round steel billet that needs to be corrected by moving in the middle of the grooves 43.

[0023] Two symmetrically distributed slots 16 are provided on the upper part of each of the two support rods 12. Multiple limiting blocks 14 are slidably locked inside the slots 16. By setting the slots 16, the limiting blocks 14 are slidably locked inside the slots 16, which facilitates the subsequent limiting of the limiting blocks 14 by bolts 17.

[0024] Each of the multiple limiting blocks 14 has a limiting hole 15, and two bolts 17 slide through the limiting hole 15. By setting the limiting hole 15, the limiting block 14 can be limited and fixed after the bolts 17 slide through the limiting hole 15.

[0025] A conveyor belt 21 is installed in the middle of one side of the frame 2. By setting the conveyor belt 21, the conveyor belt 21 can be rotated under the drive of the servo motor to transport the straightened round steel billet.

[0026] Working principle: In actual use, by placing the round steel billet on the placement plate 41, the first motor 3 is started, which drives the rotating shaft 35 to rotate, causing the two first synchronous pulleys 32 to rotate. Through the transmission of the synchronous belt 34, the second synchronous pulley 33 rotates, thereby driving the cam 36 to rotate, which in turn drives the moving frame 37 to move, thus removing the round steel billets placed on the placement plate 41 one by one. After the moving frame 37 moves to the side of the limiting plate 38, it moves downwards, placing the round steel billet on the limiting plate 38. 8. At the upper part, since one side of the limiting plate 38 is inclined, the round steel billet rolls to one side of the limiting plate 38. The moving gripper 22 moves to the upper part of the round steel billet to clamp it, thereby transferring it to the upper part of the limiting frame 51. The straightening device 5 and the moving plate 11 move simultaneously to cooperate with each other to straighten it. After straightening, the moving gripper 22 clamps and transfers it to the upper part of the conveyor belt 21. At the same time, the servo motor drives the conveyor belt 21 to move, thereby conveying the straightened round steel billet.

[0027] By rotating the nut 18, the nut 18 can be removed from one side of the bolt 17, allowing the bolt 17 to be removed from the upper side of the support rod 12, thereby enabling the disassembly and replacement of the card holder 13.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
