Abstract
Description
Technical Field
[0001] The utility model relates to a coiler pressure roll device, belonging to the technical field of auxiliary equipment in the steel rolling workshop of the metallurgical industry. Background Technique
[0002] A coiler is an auxiliary equipment in the steel rolling workshop that winds hot-rolled or cold-rolled steel into a reel shape. Generally, a coiler consists of core equipment such as a reel, a coiling roll, and a pressure roll. During the product coiling process, the product is mainly formed on the reel. The reel is generally driven by a motor, and the auxiliary coiling equipment, the coiling roll, generally rotates by being driven by a motor. A fluid hydraulic cylinder drives the coiling roll to move to assist in smooth coiling. The main function of the pressure roll is to flatten the steel strip. The traditional coiler pressure roll device for hot rolling only flattens the steel strip and cannot limit the two sides of the steel strip, which easily leads to uneven sides of the steel coil, affecting aesthetics and safe transportation.
[0003] Therefore, to solve the above problems, we propose a coiler pressure roll device. Content of the Utility Model
[0004] The purpose of the utility model is to provide a coiler pressure roll device that can not only flatten the steel strip but also limit the two sides of the steel strip, which is beneficial for the coiler to wind out neat and beautiful steel coils and solve the problems in the background technique.
[0005] The technical solution of the utility model is as follows:
[0006] A coiler pressure roll device includes a base, vertical support plates, a lower pressure roll, an upper pressure roll, outer rings, inner rings, positioning screws, and return springs. There are two vertical support plates, and the two vertical support plates are respectively vertically fixed on the base. The two ends of the lower pressure roll and the upper pressure roll are respectively rotatably connected to the two vertical support plates. The lower pressure roll is connected to a driving mechanism. One outer ring and one inner ring are provided at both ends of the upper pressure roll. The outer ring is fixed on the upper pressure roll, and the inner ring is slidably connected to the upper pressure roll. The outer ring and the inner ring are connected by a positioning screw, and a return spring is provided on the positioning screw.
[0007] The distance between the inner rings at both ends of the upper pressure roll matches the width of the steel strip coiled by the coiler.
[0008] The distance between the outer rings at both ends of the upper pressure roll is greater than the roll body length of the lower pressure roll.
[0009] The inner diameters of the outer ring and the inner ring match the diameter of the upper pressure roll.
[0010] The outer diameter of the inner ring is greater than the diameter of the upper pressure roll, and the outer diameter of the outer ring is greater than the outer diameter of the inner ring.
[0011] There are four positioning screws evenly arranged in the circumferential direction between the outer ring and the inner ring.
[0012] The outer ring is provided with threaded holes that cooperate with the positioning screw, and the inner ring is provided with blind holes that cooperate with the positioning screw.
[0013] The return spring on the positioning screw is located between the outer ring and the inner ring.
[0014] The beneficial effects of the present utility model are as follows: When the upper pressure roller and the lower pressure roller press and wind the steel strip, the two inner rings are used to squeeze and limit both sides of the steel strip, ensuring that the edges of the steel coil are conveyed in a straight line, which is beneficial for the coiler to wind out a neat and beautiful steel coil.

Detailed Embodiment
[0020] The following further illustrates the present utility model through examples in conjunction with the drawings.
[0021] Referring to the attached Figures 1-4 , a coiling machine pressure roller device includes a base 1, vertical support plates 2, a lower pressure roller 3, an upper pressure roller 4, an outer ring 7, an inner ring 8, a positioning screw 9, and a return spring 10. There are two vertical support plates 2, and the two vertical support plates 2 are respectively vertically fixed on the base 1. The two ends of the lower pressure roller 3 and the upper pressure roller 4 are respectively rotatably connected to the two vertical support plates 2. The lower pressure roller 3 is connected to a driving mechanism. One outer ring 7 and one inner ring 8 are provided at both ends of the upper pressure roller 4. The outer ring 7 is fixed on the upper pressure roller 4, and the inner ring 8 is slidably connected to the upper pressure roller 4. The outer ring 7 and the inner ring 8 are connected by a positioning screw 9, and a return spring 10 is provided on the positioning screw 9.
[0022] In this embodiment, referring to the attached Figures 1-4, The coiler pressure roll device includes a base 1, vertical support plates 2, a lower pressure roll 3, and an upper pressure roll 4. The two vertical support plates 2 are respectively welded vertically on the base 1. A rotatable lower pressure roll 3 and upper pressure roll 4 are arranged between the two vertical support plates 2. At the center of both ends of the lower pressure roll 3, a first rotating shaft 5 is welded and fixed. The outer end of the first rotating shaft 5 is rotatably connected to the vertical support plate 2. At the center of both ends of the upper pressure roll 4, a second rotating shaft 6 is welded and fixed, and the outer end of the second rotating shaft 6 is rotatably connected to the vertical support plate 2. Bearings 14 are arranged at the connection positions of the first rotating shaft 5 and the second rotating shaft 6 with the vertical support plate 2 to facilitate fixation and rotation. The outer end of the first rotating shaft 5 extends to the outside of the vertical support plate 2 and is fixedly connected with a belt pulley 11, which is convenient for connecting with the driving motor and helps to convey the steel strip.
[0023] The upper pressure roll 4 is located directly above the lower pressure roll 3, and there is a gap between them for placing the steel strip to flatten it. At both ends of the upper pressure roll 4, an outer ring 7 is sleeved and fixed. The outer diameter of the outer ring 7 is larger than the diameter of the upper pressure roll 4. The length of the lower pressure roll 3 is less than the distance between the two outer rings 7 to prevent the lower pressure roll 3 from contacting the outer ring 7 and ensure that the inner ring 8 can extrude and limit steel strips of different widths.
[0024] At both ends of the upper pressure roll 4, inner rings 8 that can move horizontally along it are also sleeved. The distance between the two inner rings 8 matches the width of the steel strip.
[0025] Four threaded holes 12 are evenly opened on the outer ring 7. Blind holes 13 directly facing the threaded holes 12 are opened on the outer side surface of the inner ring 8. Four positioning screws 9 are respectively screwed into the four threaded holes 12, and their ends are abutted in the blind holes 13. The inner ring 8 is pushed by squeezing the positioning screws 9 to limit both sides of the steel strip, which is beneficial for the coiler to wind out neat and beautiful steel coils. At the same time, the inner ring 8 can also be limited by the positioning screws 9 to prevent it from rotating on the upper pressure roll 4 and improve the stability of the overall structure.
[0026] Four positioning screws 9 are respectively sleeved with return springs 10. The two ends of the return springs 10 are respectively fixed on the outer ring 7 and the inner ring 8 and are used to pull the inner ring 8 outwards. After the positioning screws 9 are rotated outwards, the inner ring 8 can be pulled outwards to make it automatically reset, which helps to limit steel strips of different widths.
[0027] Principle and advantages of the present utility model: The steel strip processed by the hot rolling process is passed through the gap between the lower pressure roll 3 and the upper pressure roll 4, and its end is then connected to the coiler. The coiler pulls the steel strip and winds it into a cylindrical shape. Then, the positioning screws 9 are rotated inwards in sequence to push the inner rings 8 inwards, so that the two inner rings 8 are attached to the edges on both sides of the steel strip to limit both sides of the steel strip. When pulling the steel strip, its edges are kept in transportation to ensure that the side of the wound steel coil is neat and on the same plane, greatly improving the aesthetics.
