Description

Technical Field

[0001] This utility model belongs to the technical field of straightening devices, and more specifically, it relates to a special straightening roller device for π-shaped steel. Background Technology

[0002] In the production of π-shaped steel, in order to avoid the bending phenomenon of π-shaped steel affecting its subsequent normal application, straightening rollers are often used to squeeze the π-shaped steel to change its original bending state, thereby achieving the purpose of straightening.

[0003] Based on the above, in the actual application of the straightening roller device, iron oxide scale and dirt on the surface of π-shaped steel are very easy to adhere to the surface of the straightening roller. In order to avoid the impact of dirt residue on the straightening roller on the straightening effect of π-shaped steel, operators often need to manually clean multiple straightening rollers regularly. This not only increases the workload of operators, but also takes a lot of time, affecting the cleaning efficiency of the straightening roller device. Utility Model Content

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figures 1-4 As shown:

[0025] This utility model provides a special straightening roller device for π-shaped steel, including a support frame 1, a drive shaft 2, straightening rollers 3, cleaning rollers 4, movable brackets 5, and a cleaning auxiliary mechanism. There are two drive shafts 2, which are rotatably connected to the upper and lower sides of the inner end of the support frame 1, respectively. The outer side of the upper drive shaft 2 is coaxially and fixedly connected to the rotating shaft of the drive motor. There are multiple straightening rollers 3, which are vertically rotatably arranged on the outer side of two drive shafts 2, with the positions of adjacent straightening rollers 3 staggered vertically. There are multiple cleaning rollers 4, which are slidably arranged on the outer side of multiple straightening rollers 3. There are multiple movable brackets 5, which are slidably arranged on the inner end face of the straightening rollers 3. Movable brackets 5 on the same side are rotatably connected to cleaning rollers 4. The cleaning auxiliary mechanism is arranged between the straightening rollers 3, movable brackets 5, and cleaning rollers 4.

[0026] Among them, the outer sides of the left and right end faces of the drive shaft 2 are provided with the first belt pulley transmission assembly 201. The drive shaft 2 on the same side above and below is connected to the straightening roller 3 by a bevel gear transmission assembly 202.

[0027] Among them, the straightening roller 3 has a straightening auxiliary component 301 coaxially fixedly connected to the outer side of the front and rear end faces; the straightening auxiliary component 301 is a conical structure that is inclined from the outside to the inside; straightening auxiliary grooves 302 are opened on the front and rear sides of the lower straightening roller 3.

[0028] The front and rear ends of the cleaning roller 4 are coaxially fixedly connected with tapered auxiliary parts 401; the tapered auxiliary parts 401 on the same side are in contact with the correction auxiliary parts 301; the outer end of the lower cleaning roller 4 is concentrically fixedly connected with the alignment position of the straightening auxiliary groove 302 with a cleaning compensation part 402.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In use, this invention employs a correction auxiliary component 301 to assist in the correction of the π-shaped steel when it is placed, ensuring that the π-shaped steel is positioned in the center of the straightening roller 3. When the drive motor is started, the first pulley transmission assembly 201 drives the two drive shafts 2 to rotate synchronously. During the synchronous rotation of the two drive shafts 2, the bevel gear transmission assembly 202 drives the upper and lower straightening rollers 3 to rotate relative to each other. The relative rotation of the upper and lower straightening rollers 3 achieves the straightening process of the π-shaped steel. The cooperation of the conical auxiliary component 401 and the cleaning compensation component 402 ensures comprehensive cleaning of the contact surface between the straightening roller 3 and the π-shaped steel, improving the cleaning effect of the straightening roller 3.

[0031] Example 2: Based on Example 1, such as Figures 3-5 As shown:

[0032] Among them, the inner end face of the movable bracket 5 is fixedly connected to the limiting auxiliary frame 501, which is a T-shaped frame structure; a T-shaped limiting guide groove is opened on the inner side of the support frame 1 at the position aligned with the limiting auxiliary frame 501; the T-shaped limiting guide groove is fixedly connected to the limiting auxiliary frame 501; and an elastic connector 502 is fixedly connected between the limiting auxiliary frame 501 and the support frame 1.

[0033] The cleaning auxiliary mechanism includes: a drive gear 6 and a drive rack 601. There are multiple drive gears 6, which are coaxially fixedly connected to the inner end faces of multiple straightening rollers 3. There are multiple drive racks 601, which are fixedly connected to the outer ends of multiple movable supports 5. The drive racks 601 on the same side mesh with the drive gears 6.

[0034] The cleaning auxiliary mechanism also includes: a transmission shaft 602, a transmission gear 603, and a second pulley transmission assembly 604. There are multiple transmission shafts 602, which are rotatably connected to the upper ends of multiple movable supports 5. There are multiple transmission gears 603, which are coaxially fixedly connected to the outer ends of multiple transmission shafts 602. The transmission gears 603 on the same side mesh with the drive gear 6. There are multiple second pulley transmission assemblies 604, which are respectively arranged between multiple cleaning rollers 4 and transmission shafts 602.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When this utility model is in use, after the π-shaped steel is straightened, the drive motor rotates in the reverse direction. The drive gear 6 pushes the drive rack 601 and the movable bracket 5 to slide inward synchronously. The limiting auxiliary frame 501 and the elastic connector 502 guide and limit the sliding of the movable bracket 5. After the movable bracket 5 slides inward synchronously, the transmission gear 603 on the same side meshes with the drive gear 6. During the rotation of the drive gear 6, the transmission gear 603 is pushed synchronously. During the rotation of the transmission gear 603, the second pulley transmission assembly 604 pushes the cleaning roller 4 to rotate. During the relative rotation of the cleaning roller 4 and the straightening roller 3, the surface dirt of the straightening roller 3 is automatically cleaned. When the drive motor rotates in the forward direction to straighten the π-shaped steel, the drive gear 6 pushes the drive rack 601 to make the movable bracket 5 slide outward. At this time, the cleaning roller 4 moves away from the straightening roller 3.
