Description

Technical Field

[0001] This utility model belongs to the field of pressing and spreading technology, specifically relating to a pressing and spreading device for rolling strip steel. Background Technology

[0002] With the rapid development of modern industry, the demand for strip steel products is constantly increasing. As a material with high strength and good corrosion resistance, strip steel is widely used in many fields, including but not limited to automobile manufacturing, aerospace, electronic equipment, shipbuilding, bridge construction, building, instrument manufacturing, and household appliances.

[0003] After processing, steel strip is usually bent into coils for easy transport and storage. To facilitate the use of steel strip, it is usually necessary to unroll the steel strip coil and flatten the steel strip for subsequent cutting and processing. Traditional steel strip stretching operations generally adopt a structure in which the head end of the steel strip is squeezed through the stretching rollers. However, in the initial stage, after the head end of the steel strip is unrolled from the steel strip coil, it is difficult to directly squeeze through the extrusion rollers due to the structural strength limitation of the steel strip itself. Therefore, this application proposes a stretching device for rolling steel strip. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressing and spreading device for rolling strip steel, which aims to solve the technical problem of inconvenient operation in the strip steel spreading under the existing technology.

A hydraulic push rod for pushing the auxiliary roller to move downward is installed at the top end of the second vertical arm.

[0007] Preferably, each of the pair of second vertical arms has a vertical groove, in which a slider is slidably embedded. The auxiliary roller is rotatably installed between the pair of sliders, and the telescopic end of the hydraulic push rod extends into the groove and connects with the slider.

[0008] Preferably, the slider is configured as a rectangular structure, and the sidewall of the slider slides in contact with the inner sidewall of the groove.

[0009] Preferably, a guide groove is vertically formed on the side wall of the second vertical arm, the guide groove is connected to the sliding groove, a guide block is slidably embedded in the guide groove, and the guide block is fixedly connected to the slider.

[0010] Preferably, the first vertical arm, the second vertical arm, and the bottom of the side plate are all provided with mounting ear plates, which are bolted to the base plate.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes auxiliary rollers and power rollers. A shaft passing through the core of a steel strip coil is suspended at the top of a pair of first vertical arms. The end of the steel strip passes between the auxiliary rollers and the power rollers. A hydraulic pusher is activated to push the auxiliary rollers downwards, pressing the end of the steel strip against the auxiliary rollers and the power rollers. A first motor is activated to rotate the power rollers, causing the end of the steel strip to move towards the calendering rollers, forcing it through the space between the two rows of calendering rollers. A second motor is then activated to rotate the corresponding calendering rollers, allowing the steel strip to be conveyed again. Thus, under the combined action of the rotating power rollers and the pressing action of the auxiliary rollers, the steel strip continuously unfolds from the steel strip coil towards the two rows of calendering rollers. The steel strip is conveyed and flattened by two rows of calendering rollers, achieving the purpose of stretching the steel strip and facilitating its subsequent processing. During the process, the auxiliary roller is moved upward by the retraction of the hydraulic push rod, which increases the distance between the auxiliary roller and the power roller. This facilitates the steel strip end to pass between the auxiliary roller and the power roller for conveying and stretching. Through the rotation of the power roller, the pressing action of the auxiliary roller, and the rotation of the corresponding calendering roller driven by the second motor, the steel strip is conveyed smoothly, ensuring the smoothness of the steel strip stretching process. Compared to directly passing the steel strip end through the two rows of calendering rollers, this method reduces the difficulty of operation and is more practical. Attached image description:

[0023] 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.

[0024] This embodiment provides a rolling device for rolled strip steel, the structural schematic diagram of which is shown below. Figures 1-4As shown, the device includes a base plate 1. A pair of first vertical arms 2 are vertically fixed to one end of the upper surface of the base plate 1. A shaft 3 for supporting a steel strip coil is rotatably mounted between the top ends of the pair of first vertical arms 2. Specifically, a shaft groove 18 is provided at the top end of the first vertical arm 2, and the end of the shaft 3 is fitted into the shaft groove 18. A bearing bush 16 is provided at the top end of the first vertical arm 2 and fastens to the shaft 3. The two ends of the bearing bush 16 are bolted to the first vertical arm 2. The shaft 3 is passed through the core of the steel strip coil and then hoisted to the top end of the pair of first vertical arms 2. The bearing bush 16 and the shaft groove 18 are used to fasten and limit the two ends of the shaft 3. Thus, the steel strip coil can be assembled at the top end of the pair of first vertical arms 2, and the rotation of the shaft 3 facilitates the unfolding of the steel strip on the steel strip coil. A retaining ring 17 is provided on the outer wall of the shaft 3 near both ends. A pair of retaining rings 17 are located between the pair of first vertical arms 2 to limit the shaft 3 and prevent the shaft 3 from moving between the top ends of the pair of first vertical arms 2.

[0025] In a further embodiment, a pair of side plates 5 are vertically fixed to the other end of the upper surface of the base plate 1. Two rows of stretching rollers 6 are rotatably mounted between the pair of side plates 5. The two rows of stretching rollers 6 are distributed vertically. The steel strip is pulled and squeezed through the two rows of stretching rollers 6 and conveyed between them. After being rolled by the two rows of stretching rollers 6, the steel strip can be flattened, achieving the purpose of stretching the steel strip. A second motor 20 is mounted on one of the side plates 5. The output shaft of the second motor 20 is connected to one of the stretching rollers 6. Starting the second motor 20 drives the corresponding stretching roller 6 to rotate, which can squeeze and convey the steel strip.

[0026] In a further embodiment, a conveying mechanism 4 is provided between the first vertical arm 2 and the side plate 5. The conveying mechanism 4 includes a pair of second vertical arms 7 vertically fixed to the upper surface of the base plate 1. A power roller 8 is rotatably mounted between the bottoms of the pair of second vertical arms 7, and an auxiliary roller 10 is rotatably mounted between the tops of the pair of second vertical arms 7. A first motor 9 for driving the power roller 8 to rotate is mounted on one of the second vertical arms 7, and a hydraulic push rod 11 for pushing the auxiliary roller 10 downward is mounted on the top of the second vertical arm 7. The end of the steel strip is passed between the auxiliary roller 10 and the power roller 8. The hydraulic push rod 11 is activated to push the slider 13 down along the slide groove 12, pushing the auxiliary roller 10 down and pressing the end of the steel strip against the auxiliary roller. Between the power roller 8 and the auxiliary roller 10, the first motor 9 is started to drive the power roller 8 to rotate, which can drive the steel strip end towards the stretching roller 6, so that the steel strip end is squeezed through the two rows of stretching rollers 6 for stretching. When the hydraulic push rod 11 retracts and drives the auxiliary roller 10 to move upward, it can widen the distance between the auxiliary roller 10 and the power roller 8, which is conducive to the steel strip end passing through the auxiliary roller 10 and the power roller 8 for conveying and stretching processing. Through the rotation of the power roller 8 and the pressing cooperation of the auxiliary roller 10, as well as the second motor 20 driving the corresponding stretching roller 6 to rotate, the steel strip can be conveyed, ensuring the smoothness of the steel strip stretching process. Compared with directly passing the steel strip end through the two rows of stretching rollers 6, the operation difficulty is reduced.

[0027] In this embodiment, each of the pair of second vertical arms 7 has a vertically formed groove 12, and a slider 13 is slidably embedded in the groove 12. An auxiliary roller 10 is rotatably mounted between the pair of sliders 13. The telescopic end of the hydraulic push rod 11 extends into the groove 12 and connects with the slider 13. The slider 13 is a rectangular structure, and its sidewall is slidably fitted with the inner sidewall of the groove 12. A guide groove 14 is vertically formed on the sidewall of the second vertical arm 7, and the guide groove 14 communicates with the groove 12. A guide block 15 is slidably embedded in the guide groove 14, and the guide block 15 is fixedly connected to the slider 13 to guide the lifting and lowering of the auxiliary roller 10.

[0028] In this embodiment, mounting ear plates 19 are provided at the bottom of the first vertical arm 2, the second vertical arm 7, and the side plate 5, and the mounting ear plates 19 are bolted to the base plate 1.

[0029] Working principle: In use, the shaft 3 is passed through the core of the steel strip coil and then hoisted to the top of a pair of first vertical arms 2. The bearing bush 16 and the shaft groove 18 are used to fasten and limit the two ends of the shaft 3. The head end of the steel strip is passed between the auxiliary roller 10 and the power roller 8. Then, the hydraulic push rod 11 is activated to push the slider 13 down along the slide groove 12, pushing the auxiliary roller 10 down and pressing the head end of the steel strip against the auxiliary roller 10 and the power roller 8. Then, the first motor 9 is activated to drive the power roller 8 to rotate, driving the head end of the steel strip towards the calendering roller 6 until the head end of the steel strip is squeezed through the two rows of calendering rollers 6. Then, the second motor 20 is activated to drive the corresponding calendering roller 6 to rotate, and the steel strip is conveyed again. Thus, the steel strip is conveyed by the rotation of the power roller 8 and the auxiliary roller 10. Under the pressure of the 0, the steel strip is continuously unfolded from the coil and conveyed to the two rows of calendering rollers 6. After being pressed by the two rows of calendering rollers 6, the steel strip is flattened, achieving the purpose of extending the steel strip, so as to facilitate the subsequent cutting of the steel strip. During the whole process, when the hydraulic push rod 11 retracts and drives the auxiliary roller 10 to move upward, it can widen the distance between the auxiliary roller 10 and the power roller 8, which is conducive to the steel strip end passing through the space between the auxiliary roller 10 and the power roller 8 for preparation for conveying and extending processing. Through the rotation of the power roller 8 and the pressure of the auxiliary roller 10, as well as the second motor 20 driving the corresponding calendering roller 6 to rotate, the steel strip can be conveyed, ensuring the smoothness of the steel strip extension process. Compared with directly passing the steel strip end through the two rows of calendering rollers 6, the operation difficulty is reduced and it is more practical.
