Description

Technical Field

[0001] This utility model relates to the technical field of profiles, and in particular to the technical field of hexagonal steel straightening. Background Technology

[0002] Hexagonal steel may be bent during the production process for various reasons, which will affect its performance and appearance quality. Therefore, it is necessary to straighten the hexagonal steel.

[0003] Existing patent CN119635284A discloses a hexagonal steel straightening and polishing device, which straightens the hexagonal steel through a straightening sleeve. However, since the straightening sleeve is a rigid sleeve, it will generate a lot of friction with the hexagonal steel when straightening it. This will make both the hexagonal steel and the straightening sleeve easy to wear, which will not only affect the product quality of the hexagonal steel, but also reduce the service life of the straightening sleeve. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a hexagonal steel straightening device that makes both the hexagonal steel and the straightening cylinder less prone to wear, thus ensuring the product quality of the hexagonal steel and the service life of the straightening cylinder.

[0005] To achieve the above objectives, this utility model proposes a hexagonal steel straightening device, including a frame, a straightening cylinder, and a pulling mechanism. A straightening cylinder is mounted on the frame and is used to pass through the hexagonal steel. The straightening cylinder consists of a hexagonal tube, straightening components, and a base. The hexagonal tube is horizontally positioned with openings at both ends, allowing the hexagonal steel to pass horizontally through it. Three straightening components are provided on the hexagonal tube, arranged sequentially along its length. Each straightening component consists of two straightening rollers, with the two rollers within the same straightening component positioned separately. The straightening rollers are installed on two opposite side walls of the hexagonal cylinder. The central axes of the two straightening rollers in the same straightening assembly are located on a vertical plane perpendicular to the central axis of the hexagonal cylinder. The two straightening rollers in the same straightening assembly clamp the hexagonal steel. A straightening roller is installed on each side wall of the hexagonal cylinder. The six faces of the hexagonal steel are respectively in contact with the six straightening rollers. A base is installed at the bottom of the hexagonal cylinder. The base is fixed to the frame. A pulling mechanism for pulling the hexagonal steel is installed on the frame. The pulling mechanism is located on the discharge side of the straightening cylinder.

[0006] Preferably, the hexagonal cylinder has a mounting groove on its side wall, the mounting groove penetrating the side wall of the hexagonal cylinder, and the straightening roller is installed in the mounting groove.

[0007] Preferably, the length of the straightening roller is greater than the width of the hexagonal steel end face that contacts the straightening roller.

[0008] Preferably, the lower end face of the hexagonal cylinder is a horizontal plane.

[0009] Preferably, the frame is equipped with several lifting rollers located on the feed side of the straightening cylinder, and the lifting rollers support the hexagonal steel.

[0010] Preferably, the lifting roller is provided with two limiting rings, and the limiting rings and the lifting roller together form a lifting groove adapted to the hexagonal steel.

[0011] The beneficial effects of this utility model are as follows: By installing six straightening rollers on the six side walls of the hexagonal cylinder respectively, and with the straightening rollers clamping the hexagonal steel in pairs, the hexagonal steel is not easily worn while being straightened, thus effectively ensuring the quality of the product; since the friction between the hexagonal steel and the straightening rollers is rolling friction, the straightening rollers are not easily worn, thus ensuring the service life of the straightening cylinder.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0017] Example 1:

[0018] See Figure 1 and Figure 2 The present invention relates to a hexagonal steel straightening device, comprising a frame 1, a straightening cylinder, and a pulling mechanism 10. A straightening cylinder is installed on the frame 1 and is used to pass through the hexagonal steel 3. The straightening cylinder is composed of a hexagonal cylinder 2, a straightening component, and a base 25.

[0019] The hexagonal cylinder 2 is horizontally positioned with openings at both ends. The hexagonal steel 3 passes horizontally through the hexagonal cylinder 2. The hexagonal cylinder 2 is equipped with three straightening components, which are arranged sequentially along the length of the hexagonal cylinder 2. Each straightening component consists of two straightening rollers 21. The two straightening rollers 21 in the same straightening component are respectively installed on two opposite side walls of the hexagonal cylinder 2. The central axis of the two straightening rollers 21 in the same straightening component is located on a vertical plane perpendicular to the central axis of the hexagonal cylinder 2. The two straightening rollers 21 in the same straightening component clamp the hexagonal steel 3. Each side wall of the hexagonal cylinder 2 is equipped with a straightening roller 21, and the six faces of the hexagonal steel 3 are respectively in contact with the six straightening rollers 21.

[0020] A base 25 is installed at the bottom of the hexagonal cylinder 2, and the base 25 is fixed to the frame 1.

[0021] A pulling mechanism 10 for pulling hexagonal steel 3 is installed on the frame 1. The pulling mechanism 10 is located on the discharge side of the straightening cylinder.

[0022] To facilitate the installation of the straightening roller 21, the hexagonal cylinder 2 has a mounting groove 20 on its side wall. The mounting groove 20 penetrates the side wall of the hexagonal cylinder 2, and the straightening roller 21 is installed in the mounting groove 20.

[0023] To ensure the straightening effect, the length of the straightening roller 21 is greater than the width of the end face of the hexagonal steel 3 that contacts the straightening roller 21.

[0024] Example 2:

[0025] In order to allow the hexagonal steel 3 to easily enter the straightening cylinder without twisting, the lower end face of the hexagonal cylinder 2 is a horizontal plane.

[0026] Example 3:

[0027] In order to prevent the hexagonal steel 3 from bending due to its own weight during feeding, several lifting rollers 11 are installed on the frame 1. The lifting rollers 11 are located on the feeding side of the straightening cylinder and support the hexagonal steel 3.

[0028] To prevent the hexagonal steel 3 from swaying during feeding, the lifting roller 11 is provided with two limiting rings 12. The limiting rings 12 and the lifting roller 11 together form a lifting groove 13 adapted to the hexagonal steel 3.

[0029] The working process of this utility model:

[0030] In the operation of this utility model hexagonal steel straightening device, the hexagonal steel 3 passes through the hexagonal cylinder 2, and the pulling mechanism 10 drives the hexagonal steel 3 to move. When the hexagonal steel 3 passes through the hexagonal cylinder 2, the three straightening components on the hexagonal cylinder 2 straighten the hexagonal steel 3 in three directions respectively. After leaving the hexagonal cylinder 2, the hexagonal steel 3 is straightened and has good straightness.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
