[0003] The patent application CN201676881U, which was authorized and announced, discloses a reducing-rolling anchor rod roller wheel, characterized in that: the roller wheel is a conical structure with a gradually expanding diameter from front to back; the front part of the roller wheel corresponds to the reduced-diameter part of the rolled rough pipe, and its outer wall is a smooth structure with a gradually expanding diameter from front to back; the rear end of the roller wheel corresponds to the threaded forming part of the rolled rough pipe, and its outer wall is a threaded structure; the internal cavity of the roller wheel constitutes a cooling water chamber.
[0004] However, during the continuous rolling process of the reducing rolled anchor rod, the rollers wear out very quickly, making the anchor rods prone to bending and jamming, resulting in reduced production efficiency and excessively high roller use costs. Utility Model Content
[0005] In order to overcome the defects in the prior art of roller wear caused by continuous rolling, which makes the anchor rod easily bend and jam, resulting in reduced production efficiency and excessively high roller use costs, the utility model provides a crescent rib anchor rod roller device.
[0006] The technical solution adopted by the utility model to solve its technical problems is: a crescent rib anchor rod roller device, comprising a roller shaft, an entrance section roller and a crescent rib roller are fixed on the roller shaft, and a shaping section roller fixed to the roller shaft is provided between the entrance section roller and the crescent rib roller.
[0007] As a further improvement of the utility model, the entrance section roller, the shaping section roller and the crescent rib roller have keyways therein, and the entrance section roller, the shaping section roller and the crescent rib roller are fixedly connected to the roller shaft via pin keys.
[0008] As a further improvement of the utility model, an outlet section roller fixed to the roller shaft is provided between the shaping section roller and the crescent rib roller.
[0009] As a further improvement of the utility model, a keyway is provided in the outlet section roller, and the outlet section roller is fixedly connected to the roller shaft via a key.
[0010] As a further improvement of the utility model, the inlet section roller, the shaping section roller, the outlet section roller and the crescent rib roller are sequentially connected as a whole through pin keys.
[0011] As a further improvement of the utility model, the outer sides of the entrance section roller and the crescent rib roller are provided with limiting nuts that enable the entrance section roller, the shaping section roller, the exit section roller and the crescent rib roller to be in close contact.
[0012] Compared with the prior art, the utility model has the following beneficial effects: in this scheme, the roller shaft is connected to the driving motor through a coupling and a reducer, and is directly driven by the driving motor; the entrance section roller is a conical section along the moving direction of the anchor rod; the entrance section roller is a reduced diameter section of the roller; the shaping section roller is a cylindrical section along the moving direction of the anchor rod; the shaping section roller is a uniform section of the roller; there is no crescent rib pattern on the surface of the crescent rib roller; the roller forming section is used to roll the crescent rib of the anchor rod; the roller is shaped by the shaping section roller to reduce roller wear and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0014] Figure 1 The utility model is a structural schematic diagram of a crescent rib anchor roller device.
[0015] In the figure: 1. Roller shaft; 2. Entrance section roller; 3. Shaping section roller; 4. Exit section roller; 5. Crescent rib roller; 6. Limit nut. DETAILED DESCRIPTION
[0016] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.
[0017] Reference Figure 1 The utility model embodiment discloses a crescent rib anchor roller device, including a roller shaft 1, an entrance section roller 2 and a crescent rib roller 5 are fixed on the roller shaft 1, and a shaping section roller 3 fixed to the roller shaft 1 is provided between the entrance section roller 2 and the crescent rib roller 5.
[0018] Among them, the entrance section roller 2, the shaping section roller 3 and the crescent rib roller 5 have keyways therein, and the entrance section roller 2, the shaping section roller 3 and the crescent rib roller 5 are fixedly connected to the roller shaft 1 through pin keys.
[0019] When in use, the roller shaft 1 is connected to the drive motor through a coupling and a reducer, and is directly driven by the drive motor. The entrance section roller 2 is a conical section along the moving direction of the anchor rod, the entrance section roller 2 is a roller diameter reduction section, the shaping section roller 3 is a cylindrical section along the moving direction of the anchor rod, the shaping section roller 3 is a roller leveling section, and the crescent rib roller 5 has no crescent rib pattern on its surface, and is used to roll the roller forming section of the crescent rib of the anchor rod. The shaping of the shaping section roller 3 reduces roller wear and improves production efficiency.
[0020] An outlet section roller 4 fixed to the roller shaft 1 is provided between the shaping section roller 3 and the crescent rib roller 5. The outlet section roller 4 has a keyway therein and is fixedly connected to the roller shaft 1 through a key. The outlet section roller 4 is a secondary diameter reduction section of the roller, which reduces roller wear by reducing the diameter step by step, so that the anchor rod is not prone to bending and jamming.
[0021] The entrance section roller 2, the shaping section roller 3, the exit section roller 4 and the crescent rib roller 5 are connected as a whole in sequence through pin keys, making the overall connection more stable.
