Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a sizing horizontal roller. Background Technology

[0002] The sizing horizontal roller frame is a core component in roll forming machines used to control the lateral dimensions of the profile. It consists of multiple rollers arranged symmetrically, with grooves machined on their surfaces to match the target profile. The sizing horizontal roller frame is equipped with hydraulic or screw lifting mechanisms for adjusting the roller spacing and pressure. However, in existing technologies, producing steel pipes of different specifications requires changing the corresponding rollers. Each roller change consumes time for operation and adjustment, leading to production interruptions and reducing overall production efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a sizing horizontal roller frame to solve the problem in the prior art that when producing steel pipes of different specifications, it is necessary to change the corresponding rollers. Each time the rollers are changed, a certain amount of time is required for operation and adjustment, which leads to interruption of the production process and reduces the overall production efficiency.

[0004] To achieve the above objectives, this utility model provides a sizing horizontal roll frame, including a frame and two rolls;

[0005] Two rollers are mounted side by side and rotate on the frame. The two rollers are respectively connected to lifting components for moving them along the height direction of the frame.

[0006] Each roll includes a rotating shaft and a sleeve. The two ends of the rotating shaft are rotatably mounted on the frame, and the sleeve is fixedly mounted on the rotating shaft. The outer ring wall of the sleeve has multiple semi-circular grooves of different diameters along its axial direction.

[0007] The semi-circular grooves of the two rolls form multiple circular channels of different diameters arranged along their axial direction for the steel pipes to pass through.

[0008] Preferably, the sleeve includes multiple roller sections;

[0009] A semi-circular annular groove is formed on the outer circumference of the roller. A limiting block is fixedly provided on the inner ring of the roller along its axial direction, and a first threaded hole is formed on its radial direction. The first threaded hole is located on one side of the semi-circular annular groove.

[0010] A limiting disc is fixedly sleeved on one side of the rotating shaft, and a second threaded hole is opened at the other end along its radial direction. A limiting groove is opened on the annular wall of the rotating shaft along its axial direction, and a limiting block is slidably inserted into the limiting groove.

[0011] Multiple rollers are mounted side by side on a rotating shaft. The side wall of the roller at the head of the multiple rollers abuts against the limiting disc. A bolt is threaded into the first threaded hole of the roller at the tail of the multiple rollers, and the bolt is threaded into the second threaded hole.

[0012] Preferably, multiple insert rods are fixedly arranged on one side wall circumference of each roller, and multiple insertion holes are opened on the other side wall circumference. Multiple insert rods on one roller are inserted into multiple insertion holes on adjacent rollers.

[0013] The insertion rods and insertion holes correspond one-to-one.

[0014] Preferably, a blind hole is formed in the outer ring wall of the roller along its radial direction. The blind hole is coaxially arranged with the first threaded hole, and the diameter of the blind hole is larger than the diameter of the first threaded hole.

[0015] Preferably, the bolt is a slotted bolt or a cross bolt.

[0016] Preferably, each rotating shaft is equipped with an adjusting seat at both ends, the adjusting seat slides along the height of the frame, and the adjusting seat has an embedding groove into which the driving block is embedded;

[0017] The lifting component includes a guide rod, both ends of which are rotatably mounted on the frame, and one end is connected to a motor. The motor base is fixedly connected to the frame. Two spur gears are fixedly sleeved on the guide rod, and each spur gear meshes with a rack. One end of the rack is fixedly connected to the frame and slides along the height direction of the frame. The two racks correspond one-to-one with two driving blocks.

[0018] Preferably, one end of the shaft is connected to a drive mechanism for rotating it via a coupling.

[0019] Preferably, the motor is connected to the guide rod via a speed reducer.

[0020] The beneficial effects of the above scheme are:

[0021] Two horizontally positioned rollers are connected to a lifting mechanism that moves them along the height of the frame. The lifting mechanism adjusts the roller spacing. One end of a rotating shaft is connected to a drive mechanism used in existing technology to drive the shaft. The two shafts rotate, causing the two sleeves to rotate. Steel pipes of different specifications are pressed through circular channels of different diameters. This new design has advantages over existing technologies: steel pipes of different specifications are pressed through circular channels of different diameters, each channel designed for a specific specification, ensuring accurate dimensions and shape during pressing. Furthermore, the semi-circular grooves of the two rollers form multiple circular channels of different diameters along their axial direction for the steel pipes to pass through, allowing the structure to flexibly adapt to the production needs of different specifications of steel pipes. By simply changing the circular channels or adjusting the roller spacing, it is easy to switch to producing steel pipes of different specifications. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0035] like Figures 1-5As shown, this embodiment provides a sizing horizontal roll frame, including a frame 1 and two rolls 2. The two horizontally arranged rolls 2 are side-by-side on the frame 1 along its height direction, and both are connected to lifting components 3 for moving them along the height direction of the frame 1. Figure 1As shown, the roll 2 includes a rotating shaft 21 and a sleeve 22. The two ends of the rotating shaft 21 are rotatably mounted on the frame 1. The sleeve 22 is fixedly fitted onto the rotating shaft 21. Multiple semi-circular annular grooves 23 of different diameters are formed on the outer annular wall of the sleeve 22 along its axial direction. The semi-circular annular grooves 23 of the two rolls 2 form multiple circular channels 24 of different diameters arranged along their axial direction for steel pipes to pass through. One end of the rotating shaft 21 is connected to a drive mechanism (not shown) for rotating it via a coupling 5. The drive mechanism and coupling 5 are based on existing technology and will not be described in detail. The drive mechanism only needs to be able to drive the rotating shaft 21 to rotate. Adjusting seats 4 are installed at both ends of each rotating shaft 21. The adjusting seats 4 can be considered as bearing seats. The adjusting seats 4 are slidably mounted on the frame 1 along the height of the frame 1. The adjusting seats 4 have an embedding groove 41, into which a driving block 42 is embedded. The lifting component 3 includes a guide rod 31, with both ends of the guide rod 31 rotatably mounted on the frame 1. One end of the guide rod 31 is connected to a motor 35 via a prior art reducer 34. The reducer 34 is prior art and will not be described in detail. The base of the motor 35 is fixedly connected to the frame 1. Two spur gears 32 are fixedly mounted on the guide rod 31, meshing with racks 33. One end of the vertically arranged racks 33 is fixedly connected to a drive block 42. Each rack is slidably mounted on the frame along its height. The two racks 33 correspond one-to-one with the two drive blocks 42. When the drive motor 35 operates, it rotates the guide rod 31, which in turn rotates the two spur gears 32 on its rod. The spur gears 32 drive the racks 33 to move up and down, and the racks 33, through the drive blocks 42, drive the two adjusting seats 4 to rise and fall synchronously. Two horizontally positioned rollers 2 are connected to lifting components 3 for moving them along the height of the frame 1. The operation of the two lifting components 3 adjusts the spacing between the rollers 2. One end of a rotating shaft 21 is connected to a drive mechanism in the prior art for rotating the shaft 21. When the two shafts 21 begin to rotate, the two sleeves rotate, and steel pipes of different specifications pass through circular channels 24 of different diameters for pressing. The advantages of this new invention over the prior art are: steel pipes of different specifications pass through circular channels 24 of different diameters for pressing. Each circular channel 24 is designed for a specific specification of steel pipe to ensure accurate dimensions and shape during pressing. Furthermore, the semi-circular grooves 23 of the two rollers 2 form multiple circular channels 24 of different diameters arranged along their axial direction for steel pipes to pass through, allowing the system to flexibly adapt to the production needs of different specifications of steel pipes. By simply changing the circular channels 24 or adjusting the spacing of the rollers 2, it is easy to switch to the production of steel pipes of different specifications. It should be noted that the steel pipe described above is a pipe with a long notch, and the steel pipe is formed by bending a blank into a pipe.

[0036] like Figures 3-5As shown, the sleeve 22 includes multiple rollers 220. A semi-circular annular groove 23 is formed on the outer circumference of the roller 220. A limiting block 221 is fixedly installed on the inner ring of the roller 220 along its axial direction, and a first threaded hole 222 is formed on the roller 220 along its radial direction, located on one side of the semi-circular annular groove 23. A limiting disk 223 is fixedly sleeved on one side of the rotating shaft 21, and a second threaded hole (not shown) is formed on the other end of the rotating shaft 21 along its radial direction. A limiting groove 210 is formed on the annular wall of the rotating shaft 21 along its axial direction, and the limiting block 221 is slidably inserted into the limiting groove 210. The multiple rollers 220 are arranged side-by-side on the rotating shaft 21. One side wall of the roller 220 at the head of the multiple rollers 220 abuts against the limiting disk 223. A bolt 224 is threaded into the first threaded hole 222 on the roller 220 at the tail of the multiple rollers 220, and the bolt 224 is threaded into the second threaded hole.

[0037] like Figures 3-5 As shown, multiple roller sections 220 are arranged side-by-side on the rotating shaft 21. Bolts 224 are threaded into the first threaded hole 222 of the roller section 220 located at the tail of the roller section 220. Bolts 224 are threaded into the second threaded hole, facilitating quick and easy assembly of the sleeve 22. Multiple insert rods 225 are fixedly arranged on one side wall of each roller section 220, and multiple insertion holes 226 are opened on the other side wall of each roller section 220. Multiple insert rods 225 on one roller section 220 are inserted into the multiple insertion holes 226 on adjacent roller sections 220. Since the limiting block 221 is inserted into the limiting groove 210, the rotating shaft 21 drives the limiting block 221 to rotate. The outer ring wall of the roller section 220 has a blind hole 227 along its radial direction. The blind hole 227 is coaxial with the first threaded hole 222, and the diameter of the blind hole 227 is larger than the diameter of the first threaded hole 222. Bolt 224 is either a slotted bolt 224 or a cross bolt 224.

[0038] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
