Description

Technical Field

[0001] The utility model relates to the technical field of steel coil production, in particular to a side material coiling device for steel coil production. Background Art

[0002] Steel coils are shipped from the factory in specific widths, such as 600mm or 900mm. To be further processed into steel products, these coils must be cut to the desired width. This process inevitably produces scraps. To ensure stable and efficient operation of coil cutting equipment, specialized equipment is required to collect these scraps. Currently, the industry typically uses coilers to organize the scraps into coils, effectively and neatly collecting them.

[0003] The Chinese utility model patent application number is 201420733949.8, and the name is "Vertical Edge Material Winder for Slitting Machine". It discloses a wire arrangement device, which consists of two horizontal rollers and a neutral roller. The wire arrangement device moves up and down along the screw rod, so that the edge material is evenly wound on the winder. However, this technology still has the following technical problems during use: as the use time goes by, the diameter of the edge material roll wound on the coiler becomes larger and larger, so that the angle between the edge material and the steel strip gradually increases. On the one hand, this causes the edge material to gradually break away from the constraint of the neutral roller, resulting in the neutral roller's guiding effect on the edge material becoming worse, causing the edge material to be unable to move to the coiler accurately and timely, making the edge material prone to looseness and chaos, and thus making it impossible for the edge material to be wound on the coiler very evenly and tightly, thereby affecting the subsequent conveying and stacking of edge material rolls and reducing the working energy efficiency of the coiler; on the other hand, as the angle between the edge material and the steel strip increases, the pulling force of the edge material on the steel strip in the width direction also gradually increases, so that the shear force borne by the shear blade on the longitudinal shearing machine during the steel strip shearing process loses balance, which not only easily leads to the shear blade breaking and shortening its service life, but also causes burrs on the edge of the steel strip, affecting the quality of the steel strip.

[0004] In view of the above technical problems still existing in the prior art, the applicant believes that it is very necessary to make technical improvements thereto in order to provide a side material winding device that operates more stably and efficiently and does not affect the normal operation of the steel strip shearing device. Utility Model Content

[0005] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings, and to provide a scrap material winding device for steel coil production, which forms a rectangular channel by two vertical rollers and two longitudinal rollers, so that the rollers and the scrap material can always be in close contact, thereby generating appropriate friction, to produce a stable and reliable guiding effect, so that the scrap material can be wound very tightly on the scrap material winding machine; and the angle between the scrap material and the steel strip is stable, which is beneficial to extending the service life of the steel strip shearing tool and improving the quality of the steel strip product.

[0006] The technical solution of the present utility model is implemented as follows: a side material winding device for steel coil production includes a side material winding machine and a lifting guide mechanism arranged side by side, and its characteristics are: a transverse rectangular channel, two longitudinal rollers, and two vertical rollers are provided on the lifting end of the lifting guide mechanism, the two longitudinal rollers are arranged side by side above and below the rectangular channel, and the two vertical rollers are arranged side by side front and back in front of the rectangular channel.

[0007] Furthermore, the lifting guide mechanism also includes a hydraulic cylinder, a guide box, and a roller shell. The longitudinal roller and the vertical roller are installed in the roller shell. The hydraulic cylinder drives the roller shell to slide up and down in the guide box.

[0008] Furthermore, a slider embedded in the guide box is provided on the back of the roller housing, and the slider is connected to the hydraulic cylinder so that the hydraulic cylinder drives the slider to slide up and down in the guide box and drives the roller housing to slide up and down at the same time.

[0009] Furthermore, the roller shell is arranged to extend out of the guide box.

[0010] Furthermore, it also includes a guide wheel mechanism, which is arranged in the material incoming direction of the lifting guide mechanism.

[0011] Furthermore, the guide wheel mechanism includes a bracket, and a longitudinal guide wheel and a vertical guide wheel installed side by side on the bracket.

[0012] Beneficial effects of the utility model:

[0013] First of all, the present application forms a rectangular channel by combining two vertical rollers and two longitudinal rollers, and the edge material passes through the rectangular channel so that the edge material is constrained by the rollers in four directions of up, down, left and right. In this way, even if the diameter of the edge material roll becomes larger, due to the constraint of the outer vertical rollers, the edge material can be guided to the edge material winder, so that the edge material is evenly wound along the height direction of the edge material winder, thereby obtaining an evenly distributed and tightly wound edge material roll, which is beneficial to the transportation and stacking of the edge material roll, and is also beneficial to the stable operation of the edge material winder.

[0014] Secondly, no matter the diameter of the edge material coil formed on the edge material coiler, the relative angle formed between the edge material and the steel strip through the rectangular channel is always maintained in a relatively fixed range, that is, within the range limited by the width of the rectangular channel. In this way, the stretching angle of the edge material on the steel strip can also be kept in a reasonable range, thereby preventing the edge material from exerting excessive tension on the steel strip in the width direction, which is conducive to ensuring that the force on the blade of the edge material cutting tool is balanced, reducing the probability of chipping, and greatly improving the service life of the tool; at the same time, it can also ensure that the edge of the steel strip is sheared smoothly, greatly improving the quality of the steel strip.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0021] like Figures 1 to 4As shown, a scrap winding device for steel coil production includes a scrap winding machine 1 and a lifting guide mechanism 2 arranged side by side. In order to achieve the purpose proposed by the utility model, a transverse rectangular channel 23, two longitudinal rollers 21, and two vertical rollers 22 are provided on the lifting end of the lifting guide mechanism 2. The two longitudinal rollers 21 are arranged side by side above and below the rectangular channel 23, and the two vertical rollers 22 are arranged side by side front and back in front of the rectangular channel 23. In this way, the lifting guide mechanism 2 can constrain the edge material in the four directions of up, down, left and right, thereby preventing the edge material from escaping from the lifting guide mechanism 2 during the winding process, thereby ensuring that the edge material can always be evenly and tightly wound on the edge material coiler under the guidance of the lifting guide mechanism 2 during the production process, and at the same time it is also beneficial for the edge material coiler to be able to coil and collect the edge material in a timely and stable manner. The edge material coiling device of the present application is arranged on both sides of the steel strip shearing machine. It is preferred to fix the edge material coiling device on both sides of the frame of the steel strip shearing machine, which can save space and run synchronously with the steel strip shearing machine, so that the entire steel coil production device has high working efficiency, stable operation and reliability. In addition, the rectangular channel 23 can also prevent the edge material from generating an excessively large angle between the edge material and the steel strip, thereby avoiding the edge material from causing excessive pulling on the blade of the steel strip shearing machine, thereby preventing the blade from breaking.

[0022] like Figure 2-4 As shown, the lifting and guiding mechanism 2 further includes a hydraulic cylinder 24, a guide box 25, and a roller housing 27. The longitudinal roller 21 and the vertical roller 22 are mounted in the roller housing 27. The hydraulic cylinder 24 drives the roller housing 27 to slide up and down in the guide box 25. Compared to motor drive, the hydraulic cylinder 24 is more stable and reliable during operation, thereby better driving the roller housing 27 to slide up and down in the guide box 25, ensuring that the edge material can be wound very evenly and tightly on the edge material coiler 1.

[0023] like Figure 2 、 Figure 4 As shown, the back of the roller housing 27 is provided with a slider 26 embedded in the guide box 25. The slider 26 is connected to the hydraulic cylinder 24, so that the hydraulic cylinder 24 drives the slider 26 to slide up and down within the guide box 25, and at the same time drives the roller housing 27 to slide up and down. The slider 26 is not only simple in structure and easy to manufacture, but also embedded in the guide box 25, making the structure of the lifting guide mechanism 2 more compact, thereby saving space and reducing site costs.

[0024] like Figure 2 、 Figure 4As shown, the roller housing 27 is arranged to extend longitudinally out of the guide box 25. In this way, both the vertical roller and the longitudinal roller are placed outside the guide groove. On the one hand, there is no need to provide a through slot for the edge material to pass through the guide groove, thereby simplifying the guide groove structure and reducing processing costs. On the other hand, it is convenient to pass the edge material through the rectangular channel 23 during the initial operation. It is also convenient for workers to observe during machine operation, so that any malfunction can be discovered and handled in a timely manner.

[0025] like Figure 1 、 Figure 5 As shown, the system further includes a guide wheel mechanism 3, which is arranged in the material feeding direction of the lifting guide mechanism 2. This allows the edge material to pass through the guide wheel mechanism 3 before entering the lifting guide mechanism 2. This can further mitigate the impact of the coil shearing machine's vibration on the edge material's movement, thereby improving the stability and accuracy of the lifting guide mechanism 2 in guiding the edge material. Furthermore, it can further limit the change in the angle between the edge material and the steel strip, thereby reducing the pulling of the edge material on the steel strip in the width direction, thereby helping to extend the tool life and improve the smoothness of the steel strip product edge.

[0026] like Figure 5 As shown, the guide wheel mechanism 3 includes a bracket 31, and longitudinal guide wheels 32 and vertical guide wheels 33 mounted side by side on the bracket 31. The longitudinal guide wheels 32 and vertical guide wheels 33 are mounted side by side on the bracket 31 in sequence, thereby guiding the edge in both the longitudinal and vertical directions, reducing the impact of machine vibration on the edge material movement direction, and further improving the stability and accuracy of edge material movement.
