Description

Technical Field

[0001] This utility model relates to the field of hot-rolled coil slitting technology, specifically a cutting mechanism for hot-rolled coils. Background Technology

[0002] Hot-rolled coils are thin sheet metal products manufactured by pressing and deforming metal billets at high temperatures using a rolling mill. Due to their excellent mechanical properties, processing performance, and stability, they are widely used in various fields such as automobile manufacturing, aerospace, shipbuilding, construction, machinery, and pressure vessels. Hot-rolled coils are produced by cooling hot steel strip from the last stand of the finishing mill to a set temperature using laminar flow cooling, then coiling them into steel strip coils by a coiler. After cooling, the steel strip coils undergo different finishing processes (leveling, straightening, cross-cutting or longitudinal cutting, inspection, weighing, packaging, and marking, etc.) according to different user requirements to become steel plates, leveled coils, and longitudinally cut steel strip products. Hot-rolled coils can also be cut into coils of different widths according to customer needs.

[0003] In the application of hot-rolled coils, it is often necessary to cut the coiled hot-rolled coils into flat steel plates of a certain length. During the cutting process, the hot-rolled coils need to be uncoiled and leveled by a leveling machine, and the leveled plates are then transported to a shearing machine. The shearing machine then cuts the leveled plates into steel plates of the target length, and finally the cut steel plates are transported away by a conveying mechanism.

[0004] The travel length of the sheet metal is one of the main factors affecting cutting accuracy. Between two cuts, the travel length of the sheet metal should be exactly equal to the preset cutting length. However, in actual operation, the travel length of the sheet metal is prone to deviation due to fluctuations in conveyor speed, wear of transmission components, instrument malfunctions, and other reasons. This deviation will cause the length of the cut steel plate to not match the preset length, leading to material waste, product defects, and other adverse consequences. Therefore, there is an urgent need for a cutting mechanism for hot-rolled sheet metal to solve this problem. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution for a cutting mechanism for hot-rolled coils:

[0023] A cutting mechanism for hot-rolled coil includes a support frame 1. A positioning plate 2 is fixedly installed on the left side of the upper end face of the support frame 1, and an mounting plate 3 is slidably installed on the right side of the upper end face of the support frame 1. A top platform 4 is fixedly installed on the upper end face of both the positioning plate 2 and the mounting plate 3. A collecting frame 5 is fixedly installed on the side wall of the top platform 4. A cutting mechanism 6 is provided on the side wall of the top platform 4. A conveying mechanism 7 is provided on the inner cavity side wall of the collecting frame 5. An adjusting mechanism 8 is provided on the inner cavity side wall of the support frame 1.

[0024] Furthermore, the cutting mechanism 6 includes a frame plate 61 fixedly installed on the lower end face of the positioning plate 2 and the mounting plate 3, and a cutting motor 62 fixedly installed on the side wall of the frame plate 61. A first pulley 63 is fixedly installed on the output shaft end of the cutting motor 62. A rotating column 64 is rotatably installed in the middle of the side wall of the top platform 4. A second pulley 65 is fixedly installed on one end of the rotating column 64, and a cutting blade 66 is fixedly installed on the other end of the rotating column 64.

[0025] The first pulley 63 and the second pulley 65 are connected by a belt drive, and the cutting blade 66 is connected through the top platform 4.

[0026] It should be noted that when the hot-rolled coil is conveyed backward, the cutting motor 62 is started simultaneously, causing the first pulley 63 to rotate. With the help of the belt, the second pulley 65 will also rotate. Since the second pulley 65 is fixedly connected to the cutting blade 66 through the rotating column 64, the cutting blade 66 will rotate at high speed to cut the continuously feeding hot-rolled coil, thereby improving the cutting efficiency and quality of the entire device.

[0027] Furthermore, the conveying mechanism 7 includes a drive wheel 71 rotatably mounted on the rear side of the inner cavity of the top platform 4, and an auxiliary wheel 72 rotatably mounted on the front side of the inner cavity of the top platform 4. A guide wheel 73 is also rotatably mounted in the middle of the inner cavity of the top platform 4. A chain belt 74 is installed between the drive wheel 71, the auxiliary wheel 72 and the guide wheel 73 for transmission. A toggle block 75 is fixedly installed on the side wall of the chain belt 74.

[0028] A column 76 is fixedly installed on the rear part of the upper end face of the support frame 1. An extension seat 77 is fixedly installed on the upper part of the rear end face of the column 76 on the right side. A hexagonal column 78 is rotatably installed in the inner cavity of the extension seat 77. A conveyor motor 79 is fixedly installed on the side wall of the column 76 on the left side through the frame. The output shaft end of the conveyor motor 79 is fixedly connected to the hexagonal column 78. The hexagonal column 78 is slidably connected to the drive wheel 71.

[0029] It should be noted that after the worker places the hot-rolled coil on the top platform 4 and positions it behind the actuating block 75, the hot-rolled coil can be limited by the actuating block 75. Then, the hexagonal column 78 can be rotated by starting the conveyor motor 79. The hexagonal column 78 will drive the drive wheel 71 to rotate. At this time, under the cooperation of the auxiliary wheel 72 and the guide wheel 73, the actuating block 75 on the chain belt 74 will continuously move to achieve uniform and stable backward conveying of the hot-rolled coil.

[0030] Furthermore, the adjustment mechanism 8 includes an adjustment motor 81 fixedly installed on the lower end face of the mounting plate 3, and ear plates 82 fixedly installed on the front and rear sides of the lower end face of the mounting plate 3. A connecting rod 83 is rotatably installed in the inner cavity of the ear plate 82, and an adjustment gear 84 is fixedly installed at the front and rear ends of the connecting rod 83. A fixed rack 85 is fixedly installed on the front and rear side walls of the inner cavity of the mounting plate 3.

[0031] The output shaft of the adjusting motor 81 is fixedly connected to the connecting rod 83. The adjusting gear 84 is meshed with the fixed rack 85. The upper end of the mounting plate 3 is fixedly installed with a pulley 31. The upper end of the support frame 1 is fixedly installed with slide rails 11 on both the front and rear sides. The pulley 31 slides on the slide rails 11.

[0032] It should be noted that the worker can start the adjusting motor 81 to rotate the connecting rod 83. The adjusting gears 84 are fixedly installed at the front and rear ends of the connecting rod 83. Under the limiting constraint of the fixed rack 85, the adjusting gears 84 will roll along the fixed rack 85 in the left and right directions, so as to change the distance between the mounting plate 3 and the positioning plate 2. This enables the hot-rolled coil to be cut to different lengths, which greatly improves the practicality of the whole device.

[0033] Working principle: After the worker places the hot-rolled coil on the top platform 4, positioned behind the actuating block 75, the actuating block 75 limits the movement of the hot-rolled coil. Then, by starting the conveyor motor 79, the hexagonal column 78 rotates, driving the drive wheel 71. Simultaneously, with the cooperation of the auxiliary wheel 72 and guide wheel 73, the actuating block 75 on the chain belt 74 continuously shifts, achieving uniform and stable backward conveying of the hot-rolled coil. While conveying the hot-rolled coil backward, the cutting motor 62 is simultaneously started, causing the first pulley 63 to rotate. With the assistance of the belt, the second pulley 65 also rotates accordingly. Since the second pulley 65 is fixedly connected to the cutting blade 66 via the rotating column 64, the cutting blade 66 will rotate at high speed to cut the continuously feeding hot-rolled coil, thus improving the cutting efficiency and quality of the entire device. The operator can start the adjusting motor 81 to rotate the connecting rod 83. Adjusting gears 84 are fixedly installed at both ends of the connecting rod 83. Under the limiting constraint of the fixed rack 85, the adjusting gears 84 will roll along the fixed rack 85 in the left and right directions, so that the distance between the mounting plate 3 and the positioning plate 2 changes, enabling the cutting of hot-rolled coils of different lengths, which greatly improves the practicality of the entire device.

[0034] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
