Description

Technical Field

[0001] The invention relates to the technical field of steel rolling production, in particular to a steel rolling production equipment. Background Art

[0002] Steel rolling production equipment, namely rolling mill, is a mechanical equipment used to plastically deform metal billets. According to the different rolling temperatures, rolling mills can also be divided into hot rolling mills and cold rolling mills. Hot rolling mills are mainly used to heat billets to a certain temperature before rolling to obtain a larger deformation amount; while cold rolling mills are used to roll steel at room temperature or lower temperatures to obtain higher dimensional accuracy and surface quality.

[0003] The working principle of a rolling mill is to use a rolling system to continuously plastically deform the metal billet. During operation, the metal billet is first fed into the rolling system of the rolling mill through the feeding system, and then undergoes a series of rolling deformations in the rolling system to finally obtain the required metal sheet or profile, which is then output through the discharging system. The rolling roller is one of the most critical components in the rolling system of a rolling mill. Its working principle is to use the uneven surface of the rolling roller to extrude and stretch the metal billet, thereby causing it to undergo plastic deformation.

[0004] At present, when the steel rolling production equipment on the market is in use, the steel may be offset or skewed during transmission due to the lack of positioning and limiting components on both sides when the steel is transmitted inside the rolling mill. At the same time, the nozzles on the existing steel rolling production equipment will be blocked by scale after long-term use, making it impossible for water to be sprayed smoothly on the steel plate. As a result, the existing steel rolling production equipment is unable to perform the functions of limiting the transmission of steel and simultaneously cleaning the nozzles and steel plates.

[0025] like Fig. 9 The synchronization device 8 includes an extended front frame 28, a supporting vertical shaft 31, a worm gear 32, a rotating wheel 33 and a cam 34.

The first piston rod 30 passes through the convex plate 36 through the cam 34, so that the first piston rod 30 can drive the scraper 15 to move intermittently to the front end. When the worm 19 rotates, it can drive the worm wheel 32 to rotate, so that the rotating wheel 33 can drive the cam 34 to intermittently contact the convex plate 36.

[0026] The hydraulic cylinder 4 is fixedly mounted on the top of the equipment housing 25, the end of the support sleeve 13 away from the connecting bracket 11 is connected to the front top of the equipment housing 25, a connecting shaft is fixedly installed between the dual-axis motor 3 and the first gear 21, a threaded hole is provided inside the displacement support plate 17, a bracket base plate is fixedly mounted on the bottom of the interior of the equipment housing 25, and the end of the screw rod 18 away from the second gear 23 is rotatably connected to the supporting base plate, the front end of the connecting bracket 11 is connected to the rear end of the special-shaped extension rod 35, the extension front frame 28 is fixedly mounted on the front ends of both sides of the equipment housing 25, and the extension front frame 28 is located below the first bevel gear 20, the worm wheel 32 is meshed with the worm 19, and the steel roller 6 is connected to the electric roller 26. Vertically aligned, both ends of the dual-axis motor 3 are connected to the first gear 21, the top of the scraper strip 15 is flush with the bottom end of the nozzle 14, the second bevel gear 24 is meshed with the first bevel gear 20, the two ends of the displacement support plate 17 are slidably sleeved on the transverse bracket 16, the interior of the special-shaped air cylinder 29 is set in a hollow state, and the first piston rod 30, the special-shaped air cylinder 29 and the second piston rod 37 are set in a closed state, the cam 34 is horizontally aligned with the convex plate 36, and the convex plate 36 is inclined at 45° away from the side end of the second piston rod 37, the bottom end of the rotating wheel 33 is flush with the top of the electric roller 26, a square hole is opened inside the front end of the support sleeve 13, and the square rod is fixedly installed on the top of the rear end of the connecting bracket 11.

[0027] The working principle of the equipment provided in Example 1 is: the rear end of the equipment housing 25 is connected to the external conveying equipment so that the steel plate can be conveyed to the inside of the equipment housing 25. At the same time, the steel plate is overlapped on the electric roller 26, and the electric roller 26 can be started, so that the electric roller 26 can drive the steel plate to be conveyed to the front end. At the same time, the hydraulic cylinder 4 can be opened to drive the support base 5 to move downward until the steel roller 6 contacts the surface of the steel plate, so that the pressing can be limited, and the steel plate can be shaped by the rolling system inside the equipment housing 25 to complete the rolling work of the steel plate.

[0028] While the steel plate is being transmitted, the second bevel gear 24 is connected to the driving component inside the electric roller 26, so that when the electric roller 26 rotates, it can drive the second bevel gear 24 and the first bevel gear 20 to rotate simultaneously, and when the first bevel gear 20 rotates, it can drive the worm 19 to rotate, and when the worm 19 rotates, it can drive the worm wheel 32 to rotate, and when the worm wheel 32 rotates, it can drive the rotating wheel 33 to rotate simultaneously, and the bottom end of the rotating wheel 33 is in contact with the surface of the steel plate, so that when the rotating wheel 33 rotates, it can scrape off impurities and residual water stains attached to the surface of the steel plate.

[0029] At the same time, when the rotating wheel 33 is rotating, it can also drive the raised part of the cam 34 to rotate until it contacts the convex plate 36. The convex plate 36 is inclined at 45° away from the side end of the second piston rod 37, so that the docking smoothness of the cam 34 and the convex plate 36 can be improved. Subsequently, when the raised part of the cam 34 is rotated to be aligned with the convex plate 36, the second piston rod 37 can be driven to be completely inserted into the interior of the special-shaped air cylinder 29, so that the first piston rod 30 can drive the scraper 15 to move to the extreme position toward the front end through the special-shaped extension rod 35, and the scraper 15 can pass through the bottom end of the nozzle 14 when it moves toward the front end, so that the scale attached to the bottom end of the nozzle 14 can be removed, ensuring the smoothness of the nozzle 14 when spraying water. Subsequently, when the raised part of the cam 34 rotates and passes through the convex plate 36, the convex plate 36 will lose its extrusion force.

[0030] At this time, the elasticity of the reset spring 12 will drive the scraper 15 to reset, and the scraper 15 can pass through the bottom end of the nozzle 14 again when resetting, so that the bottom end of the nozzle 14 can be cleaned again. While the scraper 15 is resetting, the connecting bracket 11 can drive the first piston rod 30 to insert into the interior of the special-shaped air cylinder 29 through the special-shaped extension rod 35, so that the convex plate 36 and the second piston rod 37 can be reset at the same time, so that the cam 34 contacts the convex plate 36 again, completing the cleaning of the steel plate and the water outlet at the bottom end of the nozzle 14. When the device is in use, it is connected to the external water valve through the nozzle 14. When the steel plate is being transported, the water valve can be opened so that water can be sprayed on the steel plate through the nozzle 14, thereby cooling the steel plate.

[0031] At the same time, when the steel plate is being transmitted, the dual-axis motor 3 can be started to drive the first gear 21 to rotate. When the first gear 21 rotates, the transmission belt 22 can drive the second gear 23 and the screw rod 18 to rotate at the same time. The displacement support plate 17 is threadedly sleeved on the screw rod 18. Therefore, when the screw rod 18 rotates, the displacement support plate 17 can be driven to displace inside the equipment housing 25. At the same time, when the displacement support plate 17 is displaced, the guide wheel 27 can be driven to displace at the same time until the guide wheel 27 contacts the edge of the steel plate, thereby preventing the steel plate from being skewed during transmission.

[0032] Moreover, while the guide wheel 27 is displaced, the displacement support plate 17 is slidably sleeved on the transverse bracket 16, so that the displacement support plate 17 can be supported to move in a straight line, thereby improving the docking accuracy between the guide wheel 27 and the steel plate. When the device is in use, the two second gears 23 are driven to rotate simultaneously by turning on the dual-axis motor 3, so that the two displacement support plates 17 can be displaced at the same time, so that the guide wheel 27 can contact the edges of steel plates of different widths, thereby ensuring that the steel plates are transmitted in a straight line. At the same time, when the electric roller 26 is started, the rotating wheel 33 can be driven to rotate, and when the rotating wheel 33 rotates, the cam 34 can contact the convex plate 36 to drive the scraper 15 to move to the front end, so that the water stains and impurities on the surface of the steel plate and the scale accumulated at the bottom of the nozzle 14 can be removed to complete the work. Example 2

[0033] On the basis of Example 1, Fig.10 As shown, the guide wheel 27 also includes a threaded rod 38, a nut 39 and a limiting ring 40. The threaded rod 38 is fixedly mounted on the top of the guide wheel 27, the limiting ring 40 is slidably sleeved on the outer ring of the threaded rod 38, the nut 39 is threadedly sleeved on the outer ring of the threaded rod 38, and the nut 39 is located above the limiting ring 40.

[0034] When implementing this embodiment, the limiting ring 40 is slidably sleeved on the outer ring of the threaded rod 38. When the steel plate is transmitted from the side end of the guide wheel 27, the limiting ring 40 can be slidably sleeved on the threaded rod 38 until the bottom end of the limiting ring 40 contacts the top of the steel plate, and then the nut 39 is screwed on the threaded rod 38 until it contacts the top of the limiting ring 40, thereby preventing the limiting ring 40 from moving upward and completing the adaptation work with steel plates of different thicknesses.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
