Description
Technical Field
[0001] The utility model relates to the field of rolling steel transfer production, in particular to an anti-scratching device for a rolling high-quality steel guide groove. Background Art
[0002] In the high-speed wire rod workshop of iron and steel enterprises, the guide groove is an essential and important device in the rolling process, and is a common accessory that plays a guiding and positioning role when the rolled piece enters or exits the rolling mill in the rolling process. Due to direct contact and friction with the rolled piece, the guide groove is extremely prone to wear and deformation. When the wear or deformation reaches a certain degree, a steel piling accident is likely to occur during the progress of the rolled piece, resulting in production interruption. When rolling high-quality special steel, scratch lines will appear on the surface of the rolled piece after the guide groove is worn. Especially when producing cold heading quality steel, some defects of the product cannot be detected visually, affecting the quality of high-quality special steel products.
[0003] When producing high-quality rolled steel, surface scratches of the rolled steel are one of the main defects, which greatly affect product quality and production cost. Research shows that the scratches on the surface of the rolled piece are mainly caused by the friction between the equipment and the rolled piece during the rolling process. Especially, there are defects in the guide grooves between some stands during the rolling process, which are prone to generate scratches.
[0004] The specific reasons for these defective guide grooves to generate scratches are mainly that the sliding contact surface between the rolled piece and the guide groove is large, the frictional force during sliding is too large, and there are knocks, etc. In addition, the product specification range of the straight bar round steel and large-diameter wire rod production line can reach Φ (diameter) 14mm - 50mm, and the product specification span is relatively large. Therefore, for the application of the anti-scratching guide groove device on the production line, in addition to the anti-scratching requirement, it is also necessary to be able to adapt to rolled pieces of different specifications. Content of the Utility Model

[0027] To make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in combination with specific embodiments.

[0029] In the first aspect of the present utility model, as Figure 1 and Figure 2As shown in the figure, the present utility model mainly processes and improves the conventional guide groove 101, and applies an anti-scratching device to the guide groove 101 to improve the scratching condition of the surface of the rolled piece.
[0030] Specifically, first, a horizontal roller groove 104 is opened at the bottom of the guide groove 101. A horizontal roller 102 is horizontally rotatably connected in the horizontal roller groove 104. It is necessary to ensure that the upper end of the horizontal roller 102 is located above the horizontal roller groove 104, and the height difference between the upper end of the horizontal roller 102 and the bottom of the guide groove 101 is between 5 and 12 mm. Then, left and right through grooves for the vertical roller bracket 105 to pass through are opened on both side walls of the guide groove 101. The vertical roller bracket 105 passes through the side wall of the guide groove 101 through this groove and is fixed by a positioning plate 108. A vertical roller 103 is rotatably connected at the port of the vertical roller bracket 105 located inside the side wall of the guide groove 101. The vertical roller 103 is rotatably connected to the vertical roller bracket 105 through a roller 109.
[0031] A number of horizontal rollers 102 and vertical rollers 103 are provided, and they are arranged in a row at equal intervals, and the rotation directions of the horizontal rollers 102 and the vertical rollers 103 are the same as the length direction of the guide groove 101. By providing the horizontal rollers 102 and the vertical rollers 103 at the bottom and both sides of the guide groove 101 to support the rolled steel, rolling friction is used instead of sliding friction to reduce the frictional force, which not only facilitates the movement of the rolled steel in the guide groove 101, but also avoids the scratching that is prone to occur between the rolled steel and the guide groove 101 due to sliding friction. Moreover, the edges of the horizontal rollers 102 and the vertical rollers 103 are chamfered into an arc surface to further avoid scratching the rolled steel.
[0032] The key point is that, as Figure 3 and Figure 4 shown, an activity groove 110 is provided inside the vertical roller bracket 105, and a limiting groove 112 with a front end communicating with the activity groove 110 is also provided inside the vertical roller bracket 105. The roller 109 and the buffer spring 113 are movably connected in the activity groove 110, and the limiting rod 111 is slidably connected in the limiting groove 112. The roller 109 is slidably connected to the activity groove 110 and cannot perform relative rolling, while the vertical roller 103 is rotatably connected to the roller 109. The buffer spring 113 can only perform telescopic activities in the activity groove 110 and cannot perform other activities. One end of the buffer spring 113 is fixedly connected to the roller 109, and the other end is fixedly connected to the activity groove 110.
[0033] In order to ensure the stability of the roller 109 and the buffer spring 113 during activities, a limiting rod 111 is also provided in the activity groove 110 and the limiting groove 112. The outside of the limiting rod 111 is located in the activity groove 110, while the inside is located in the limiting groove 112. The limiting groove 112 is adapted to the limiting rod 111, and the limiting rod 111 can only perform telescopic sliding in the limiting groove 112.
[0034] Specifically, the inner end of the limiting rod 111 is slidably connected in the limiting groove 112, and the outer end of the limiting rod 111 is fixedly connected to the roller 109. The buffer spring 113 is sleeved on the limiting rod 111, and both ends of the buffer spring 113 are respectively connected to the roller 109 and the vertical roller bracket 105. The limiting rod 111 and the buffer spring 113 together form a buffer assembly. The buffer assembly reduces the collision force that may occur when the rolled steel enters the guide groove 101 due to an incorrect angle, and improves the scratching condition of the rolled steel caused thereby.
[0035] On the other hand, as Figure 1 , Figure 2 and Figure 3 shown, the vertical roller bracket 105 passes through the side wall of the guide groove 101 and is slidably connected thereto. A plurality of positioning grooves 106 penetrating up and down are provided on the outer vertical roller bracket 105. An opening groove matching with the positioning groove 106 is provided on the side wall of the guide groove 101. A positioning plate 108 is slidably connected in the opening groove and the positioning groove 106. Through the cooperation of the positioning plate 108, the positioning groove 106 and the opening groove on the side wall of the guide groove 101, the vertical roller bracket 105 can be fixed to the side wall of the guide groove 101. In addition, a cover plate 107 larger than the opening of the opening groove is fixedly connected to the upper end of the positioning plate 108.
[0036] Therefore, by pulling out the positioning plate 108 through the cover plate 107, the vertical roller bracket 105 can slide relative to the side wall of the guide groove 101, and thus the position of the vertical roller bracket 105 can be adjusted. Also, because a plurality of positioning grooves 106 penetrating up and down are provided on the outer vertical roller bracket 105, by selecting different positioning grooves 106, the position between the vertical roller bracket 105 and the guide groove 101 can be adjusted, and thus the distance between the two sets of opposite vertical rollers 103 is adjustable. Therefore, it can adapt to rolled steel of different sizes, making the application range of the present utility model wider. Detailed implementation manner
[0037] First, adjust the distance between the two sets of opposite vertical rollers 103 according to the size of the transported rolled steel. Pull out the positioning plate 108 through the cover plate 107 so that the vertical roller bracket 105 can slide relative to the side wall of the guide groove 101. Then, select the most suitable positioning groove 106 as needed so that the positioning groove 106 is exactly on the same vertical plane as the opening groove on the side wall of the guide groove 101. Then insert the positioning plate 108. Through the cooperation of the positioning plate 108, the positioning groove 106 and the opening groove on the side wall of the guide groove 101, the vertical roller bracket 105 is fixed to the side wall of the guide groove 101.
[0038] After the above preparatory work is completed, place the rolled steel into the guide groove 101. First, the rolled steel will fall on the horizontal roller 102, and both sides will be in contact with the vertical rollers 103. During the forward movement of the rolled steel, the horizontal roller 102 and the vertical rollers 103 will rotate in the forward direction of the rolled steel, replacing sliding friction with rolling friction to reduce the frictional force. This not only facilitates the movement of the rolled steel in the guide groove 101 but also avoids scratches that are likely to occur between the rolled steel and the guide groove 101 due to sliding friction.
[0039] Due to the intermittent arrangement of the positioning grooves 106, the adjustment of the distance between the two groups of vertical rollers 103 is not linear. In order to prevent the rolled steel from being knocked or collided when moving in the guide groove 101, a buffer device is provided between the vertical rollers 103 and the vertical roller bracket 105. The buffer device is composed of a limit rod 111 and a buffer spring 113. When the rolled steel presses against the vertical rollers 103, the vertical rollers 103 are pressed, causing the roller 109 to move in the movable groove 110, thereby squeezing the buffer spring 113. The elastic force of the buffer spring 113 provides a buffering force to reduce the impact force that may occur when the rolled steel enters the guide groove 101 due to an incorrect angle, and improves the scratching situation of the rolled steel caused thereby.
[0040] Based on the above, the present utility model supports the rolled steel by arranging a horizontal roller 102 at the bottom of the guide groove 101 and vertical rollers 103 on both sides, replacing sliding friction with rolling friction to reduce the frictional force. The edges of the horizontal roller 102 and the vertical rollers 103 are arc-shaped, which not only facilitates the movement of the rolled steel in the guide groove 101 but also effectively avoids scratches caused by sliding friction between the rolled steel and the guide groove 101. In addition, a buffer assembly is provided between the vertical rollers 103 and the vertical roller bracket 105 to reduce the impact force that may occur when the rolled steel enters the guide groove 101 due to an incorrect angle, and improves the scratching situation of the rolled steel caused thereby. The position between the vertical roller bracket 105 and the guide groove 101 is adjustable, so the distance between the two groups of opposite vertical rollers 103 is adjustable, which can adapt to rolled steel of different sizes, making the application range of the present utility model wider.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
