Description

Technical Field

[0001] This invention relates to the field of cold-rolled sheet processing equipment, and particularly to a rolling equipment for cold-rolled sheet processing. Background Technology

[0002] Metal sheet processing is divided into two methods: hot processing and cold rolling. When cold rolling metal sheets, rolling equipment is used to perform cold rolling. The processing is completed by repeatedly coiling and cold rolling the cold rolled sheet. Rolling equipment is very profitable, so it is widely used.

[0003] Chinese patent document CN115945520B discloses a rolling equipment for cold-rolled sheet processing. This equipment drives the rotating body to rotate by pushing the rack and the first drive gear, thereby switching the position of the idle take-up roller. The take-up roller switching effect can be achieved simultaneously during the unloading process of the displacement frame, eliminating a take-up roller switching step and drive structure, and improving the processing efficiency of cold-rolled sheet. However, in actual use, the device does not clean the surface of the cold-rolled sheet to be rolled. Impurities on the surface of the cold-rolled sheet may be embedded in the surface of the cold-rolled sheet during the rolling process, affecting the rolling quality of the cold-rolled sheet.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this invention, by providing a cleaning device, the surface of the cold-rolled sheet can be cleaned before rolling, so as to prevent impurities on the surface of the cold-rolled sheet from embedding into the surface of the cold-rolled sheet during the rolling process and affecting the rolling quality of the cold-rolled sheet.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1

[0038] like Figure 1 As shown in the figure, this embodiment discloses a rolling equipment for cold-rolled sheet processing, including two support seats 1, and a cleaning device 2 is provided on one side of the upper end of the two support seats 1.

[0039] Before rolling cold-rolled steel sheets, their surfaces need to be cleaned to prevent impurities from embedding into the surface and affecting the rolling quality. Figure 2 and Figure 4 As shown, the cleaning device 2 includes a centering clamping mechanism 21 and a hydraulic cylinder 22. The centering clamping mechanism 21 is fixedly installed on the upper end of two support bases 1. The hydraulic cylinder 22 is fixedly installed on one side of the outer surface of the centering clamping mechanism 21. Support plates 211 are slidably installed on both sides of the upper end of the centering clamping mechanism 21. The output end of the hydraulic cylinder 22 is fixedly connected to the middle of the support plate 211 located on one side. A hydraulic pusher 23 is provided in the middle of the lower end of the centering clamping mechanism 21. A protective plate 24 for protection is provided in the middle of the upper end of the centering clamping mechanism 21. A driven mechanism 25 is provided at the upper end of both support plates 211. Two brooms 26 are provided between the two driven mechanisms 25.

[0040] Specifically, before rolling the cold-rolled sheet, the cold-rolled sheet needs to pass between two brooms 26. Then, the hydraulic cylinder 22 pushes the support plate 211 to move. Under the action of the centering clamping mechanism 21, the support plates 211 on both sides move simultaneously. When the two support plates 211 move, they will also drive the driven mechanisms 25 on both sides to move, thereby causing the driven mechanisms 25 on both sides to move closer to each other or further away from each other. After moving a certain distance, the worker uses the hydraulic pusher 23 to drive the driven mechanism 25 to make close contact with the surface of the cold-rolled sheet.

[0041] Furthermore, when the surface of the driven mechanism 25 is in close contact with the surface of the cold-rolled plate, the movement of the cold-rolled plate will drive the driven mechanism 25 to move, thereby causing the driven mechanisms 25 on both sides to drive the two brooms 26 to reciprocate, so that the two brooms 26 clean the outer surface of the cold-rolled plate.

[0042] Furthermore, the protective plate 24 can prevent dust from falling on the upper part of the centering clamping mechanism 21 and affecting the normal operation of the centering clamping mechanism 21.

[0043] Before cleaning the surface of the cold-rolled sheet, the hydraulic pusher 23 needs to drive the driven mechanisms 25 on both sides to clamp the cold-rolled sheet, so that the two driven mechanisms 25 can move with the cold-rolled sheet. Figure 3 As shown, the hydraulic pusher 23 includes a hydraulic cylinder 231, which is fixedly installed at the lower middle of the centering clamping mechanism 21. A threaded rod 233 is provided on one side of the outer surface of the hydraulic cylinder 231 and is threadedly connected to the lower end of the centering clamping mechanism 21. Two hydraulic pipes 232 are provided on the other side of the outer surface of the hydraulic cylinder 231. The end of the threaded rod 233 near the hydraulic pipe 232 is rotatably connected to the piston end face in the inner cavity of the hydraulic cylinder 231. The inner cavities of the two hydraulic pipes 232 are connected to the inner cavity of the hydraulic cylinder 231.

[0044] Specifically, since the threaded rod 233 is threadedly connected to the lower end of the centering clamping mechanism 21, when the operator rotates the threaded rod 233, the threaded rod 233 will pull the piston in the inner cavity of the hydraulic cylinder 231 to move, thereby allowing the hydraulic oil in the inner cavities of the two hydraulic pipes 232 to enter the inner cavity of the hydraulic cylinder 231.

[0045] During the operation of the cold-rolled sheet, the force of the cold-rolled sheet's movement drives the broom 26 to clean the surface of the cold-rolled sheet, such as... Figure 4As shown, the driven mechanism 25 includes two double-headed telescopic rods 251, which are fixedly installed on the upper end of the support plate 211. Positioning plates for fixing the double-headed telescopic rods 251 are installed through the upper sides of the protective plate 24 between the two double-headed telescopic rods 251 and the support plate 211, and the positioning plates are slidably connected to the inner wall of the protective plate 24. Fixed plates are provided at the ends of the upper and lower extension rods of the two double-headed telescopic rods 251 that are far apart from each other. A driven member 252 is provided on the side of the four fixed plates near the hydraulic cylinder 231. Two pushing mechanisms 253 are provided between the four fixed plates, and the two pushing mechanisms 253 are vertically distributed. The outer surfaces of the upper and lower pushing mechanisms 253 are fixedly connected to the fixed plates located at the upper and lower parts, respectively.

[0046] Furthermore, the four double-headed telescopic rods 251 in the two driven mechanisms 25 are respectively connected to the inner cavity of the hydraulic cylinder 231 through two hydraulic pipes 232.

[0047] Specifically, when the rotating threaded rod 233 drives the hydraulic oil in the inner cavity of the hydraulic pipe 232 into the inner cavity of the hydraulic cylinder 231, the two hydraulic pipes 232 will draw the hydraulic oil in the inner cavities of the four double-headed telescopic rods 251 in the driven mechanisms 25 on both sides into the inner cavity of the hydraulic cylinder 231. This causes the extension rods on the upper and lower sides of the double-headed telescopic rods 251 to move closer to each other. In turn, the double-headed telescopic rods 251 drive the two driven members 252 to move closer to each other through the two fixed plates, thereby making the two driven members 252 in close contact with the surface of the cold-rolled plate.

[0048] Furthermore, when the two driven members 252 are in close contact with the surface of the cold-rolled plate, the movement of the cold-rolled plate will cause the driven members 252 to rotate, which in turn causes the driven members 252 to drive the push mechanism 253 to move, thereby causing the four push mechanisms 253 on both sides to drive the two brooms 26 to move respectively.

[0049] During the operation of the cold-rolled sheet, in order for the driven member 252 to drive the pushing mechanism 253 to move, and in turn, the pushing mechanism 253 drives the broom 26 to reciprocate, thereby cleaning the surface of the cold-rolled sheet, such as... Figure 5 and Figure 6 As shown, the driven member 252 includes an elastic telescopic rod 2521, which is mounted on a fixed plate. A positioning wheel 2522 is provided at the extended end of the elastic telescopic rod 2521. A driven rod 2523 is provided in the middle of the positioning wheel 2522. The driven rod 2523 is fixedly connected to the end face of the central axis of the positioning wheel 2522. A crank rocker mechanism 2524 is provided on the outer surface of the driven rod 2523 away from the hydraulic cylinder 231.

[0050] Driven by the driven component 252, the driving mechanism 253 can drive the broom 26 to reciprocate, such as... Figure 5As shown, the pushing mechanism 253 includes a limiting frame 2531, which is fixedly installed on the outer surface of two fixed plates located on one side. A slide rod 2532 is slidably installed in the middle of the inner cavity of the limiting frame 2531. The slide rod 2532 is rotatably installed on the outer surface of two crank rocker mechanisms 2524 located on one side. A connecting block 2533 is provided in the middle of the outer surface of the slide rod 2532.

[0051] Furthermore, the two connecting blocks 2533 located at the upper part and the two connecting blocks 2533 located at the lower part of the two driven mechanisms 25 are slidably connected to the outer surfaces of the two brooms 26, respectively.

[0052] Specifically, when the hydraulic pusher 23 drives the driven parts 252 on both sides to move through the double-headed telescopic rod 251, the elastic telescopic rod 2521 fixed by the fixed plate will drive the positioning wheel 2522 to move until the surface of the positioning wheel 2522 is in close contact with the surface of the cold-rolled plate. When the elastic telescopic rod 2521 and the positioning wheel 2522 move, the limit frame 2531 fixed on the fixed plate also moves accordingly.

[0053] Furthermore, when the cold-rolled plate moves, the positioning wheel 2522 can be driven to rotate by the friction between the positioning wheel 2522 and the cold-rolled plate. When the positioning wheel 2522 rotates, it can drive the crank rocker mechanism 2524 to run through the driven rod 2523, thereby causing the crank rocker mechanism 2524 to push the slide rod 2532 to slide in the inner cavity of the limit frame 2531.

[0054] Furthermore, when the four slide rods 2532 in the driven mechanisms 25 on both sides slide in the inner cavities of the four limit frames 2531 respectively, the four slide rods 2532 drive the two brooms 26 to reciprocate through the connecting block 2533, thereby enabling the brooms 26 to clean the surface of the cold-rolled plate.

[0055] Furthermore, when the hydraulic cylinder 22 pushes the driven mechanisms 25 on both sides to move towards each other through the support plate 211 and the centering clamping mechanism 21, the connecting block 2533 will slide on the outer surface of the broom 26, so that the broom 26 will not obstruct the operation of the driven mechanisms 25 on both sides.

[0056] Furthermore, since the driven mechanisms 25 on both sides can move under the drive of the centering clamping mechanism 21 and the support plate 211, the cleaning device 2 can clean the surface of cold-rolled plates of different widths.

[0057] Example 2

[0058] This embodiment further improves the winding device 4 based on Embodiment 1, such as... Figure 1 As shown, a winding device 4 is provided on the other side of the upper end of the two support bases 1, and a rolling mechanism 3 is provided in the middle of the upper end of the two support bases 1.

[0059] Specifically, such as Figure 7 As shown, the rolling mechanism 3 consists of two lower rolls, one upper roll, two hydraulic cylinders for lifting and lowering the upper roll, and a transmission mechanism for driving the two lower rolls. When the cold-rolled sheet passes through the upper and lower rolls, the upper and lower rolls can roll the cold-rolled sheet. This is prior art and will not be described in detail in this specification.

[0060] In daily production, after a certain length of cold-rolled sheet is wound around the surface of a take-up roll 44, it needs to be removed first, and then a new take-up roll 44 needs to be installed. This process is time-consuming. To facilitate the replacement of the take-up roll 44 by workers and to improve production efficiency, such as... Figure 8 As shown, the winding device 4 includes two support frames 41, both of which are fixedly installed on the upper end of the support base 1. Support rods 42 are provided on the upper part of the two support frames 41. Positioning pins 411 for fixing the support rods 42 are provided on the upper part of the outer surface of each support frame 41. Connecting rods are provided on both sides of the outer surface of the support rods 42. Limiting mechanisms 43 are provided at both ends of the two connecting rods. Winding rollers 44 are provided in the middle of the two limiting mechanisms 43 located on the same side. Limiting rods 441 are provided at both ends of the two winding rollers 44. A transmission component 45 is provided on one side of the two support frames 41.

[0061] Specifically, after a certain length of cold-rolled sheet is wound around the surface of the take-up roll 44 near the rolling mechanism 3, the transmission component 45 exits the output position, and then the two positioning pins 411 are pulled out. At this time, the positioning pins 411 will not restrict the rotation of the support rod 42. Then the operator rotates the support rod 42, causing the support rod 42 to drive the take-up roll 44 near the rolling mechanism 3 to rotate to the side away from the rolling mechanism 3. The take-up roll 44 that was originally away from the rolling mechanism 3 rotates to the side near the rolling mechanism 3. The transmission component 45 returns to the output position and drives it to rotate, so that the cold-rolled sheet is wound around its surface.

[0062] Furthermore, after completing the above actions, the worker can remove the take-up roller 44 with a certain length of cold-rolled sheet wound around it from inside the two limiting mechanisms 43. Finally, the worker places another take-up roller 44 without cold-rolled sheet wound around it into the inner cavity of the two limiting mechanisms 43, and repeats this process.

[0063] To facilitate the placement of the take-up roller 44, and simultaneously, when the transmission member 45 is not driving the take-up roller 44, the limiting mechanism 43 can restrict the take-up roller 44, such as... Figure 9 and Figure 10As shown, the limiting mechanism 43 includes two limiting members 431. The outer surface of the limiting member 431 located near the support rod 42 is fixedly connected to the end face of the connecting rod. Both the upper and lower ends of the two limiting members 431 are provided with fixing members 432 for fixing. Two supporting members 434 are provided between the two limiting members 431.

[0064] Furthermore, both support members 434 include support blocks 4341, and springs 4342 are provided on the outer surfaces of the two support blocks 4341 that are far apart from each other. The ends of the springs 4342 located on the upper and lower sides that are far apart from each other are respectively fixedly connected to the ends of the two fixing members 432 that are close to each other.

[0065] Specifically, before placing the take-up roller 44 inside the limiting mechanism 43, the upper fixing member 432 needs to be removed from the upper part of the two limiting members 431. Then, the take-up roller 44 is placed between the two limiting members 431. When the take-up roller 44 is placed between the two limiting members 431, the surface of the take-up roller 44 will contact the surface of the lower support block 4341 and be supported by the two springs 4342 at its lower end. After that, the upper fixing member 432 is re-fixed to the upper end of the two limiting members 431.

[0066] Furthermore, since the upper spring 4342 is fixedly connected to the surface of the fixing member 432, when the upper fixing member 432 is removed from the upper end of the limiting member 431, the upper support member 434 will be removed from between the two limiting members 431 along with the fixing member 432. Therefore, when the upper fixing member 432 is re-fixed to the upper end of the two limiting members 431, the upper support member 434 will also restrict the winding roller 44.

[0067] In order to restrict the winding roller 44 without hindering the transmission of the transmission component 45 to the winding roller 44, such as Figure 10 As shown, the limiting member 431 includes a limiting plate 4311. The upper and lower sides of the limiting plate 4311 are provided with fixing grooves that are adapted to the fixing member 432. A connecting groove 4312 is provided on one side of the outer surface of the limiting plate 4311, and a limiting groove 4313 is provided on the other side of the outer surface of the limiting plate 4311. A rotating groove 4314 is provided through the upper and lower sides of the limiting groove 4313.

[0068] Furthermore, the limiting groove 4313 on the surface of the limiting member 431 in the same limiting mechanism 43 is adapted to the support block 4341, and the two limiting grooves 4313 are also adapted to the limiting rod 441.

[0069] Specifically, fasteners such as buckles are provided on both sides of the end of the fastener 432 closest to the support 434. Figure 10As shown, the button in the middle can drive the two buckles to move. When the two buckles on the fixing member 432 enter the inner cavity of the fixing groove, they can be firmly fixed to the upper end of the two limiting members 431. This is the prior art, and this specification will not describe it in detail.

[0070] In order to drive the take-up roll 44 to rotate, so that the take-up roll 44 can take up the rolled cold-rolled sheet, such as Figure 11 and Figure 12 As shown, the transmission component 45 includes a support plate 451, a motor 452, and two hydraulic cylinders 453. The two hydraulic cylinders 453 are fixedly installed on the upper end of the support base 1. The output ends of the two hydraulic cylinders 453 are fixedly connected to the lower ends of the support plate 451 on both sides. The motor 452 is fixedly installed on one side of the upper end of the support plate 451. A transmission rod 454 is provided in the middle of the upper end of the support plate 451. The middle of the outer surface of the transmission rod 454 is connected to the output end of the motor 452 through a bevel gear set. Transmission blocks 456 are rotatably installed on both sides of the lower end of the support plate 451. The two transmission blocks 456 are connected to the transmission rod 454 through a belt transmission mechanism. The two transmission blocks 456 are provided with positioning grooves 4561 at their close ends, and the positioning grooves 4561 are adapted to the limit rods 441.

[0071] Specifically, when the take-up roller 44 is placed between the two limiting members 431, the plane on the limiting rod 441 will contact the surface of the limiting groove 4313 on the two limiting members 431, so that the two limiting members 431 restrict the limiting rod 441 and the take-up roller 44.

[0072] Furthermore, after the take-up roll 44 on the side near the rolling mechanism 3 winds a certain length of cold-rolled sheet, the hydraulic cylinders 453 on both sides push the support plate 451 upward, thereby causing the transmission components fixed at the upper and lower ends of the support plate 451 to move upward. During this process, the positioning groove 4561 on the end face of the transmission block 456 will gradually disengage from the limit rod 441. Then, the support rod 42 is rotated to make the take-up roll 44 on the other side rotate to the side near the rolling mechanism 3. At this time, the hydraulic cylinders 453 on both sides drive the transmission blocks 456 on both sides to move downward through the support plate 451, and make the inner surface of the positioning groove 4561 on the end face of the transmission block 456 contact the surface of the limit rod 441 located on the side near the rolling mechanism 3.

[0073] Furthermore, when the positioning groove 4561 on the transmission block 456 is in complete contact with the surface of the limiting rod 441, the hydraulic cylinder 453 will continue to drive the transmission block 456 downward, causing the transmission block 456 to drive the take-up roller 44 downward. This causes the take-up roller 44 to compress the spring 4342 located at the bottom. During the downward movement of the take-up roller 44, the surface of the limiting rod 441 will gradually disengage from the surface of the limiting groove 4313, allowing the limiting rod 441 to enter the inner cavity of the rotating groove 4314. The rotating groove 4314 will not restrict the limiting rod 441. Therefore, the motor 452 can drive the transmission block 456 to rotate through the transmission rod 454 and the belt drive mechanism, thereby causing the transmission block 456 to drive the take-up roller 44 to rotate through the limiting rod 441, thus enabling the take-up roller 44 to take up the cold-rolled sheet.

[0074] Furthermore, the connecting grooves 4312 in the two limiting mechanisms 43 that contact the two side surfaces of the take-up roller 44 will contact the end face of the take-up roller 44, which can restrict the take-up roller 44. At the same time, the transmission block 456 will also restrict the limiting rod 441. Through double restriction, the take-up roller 44 can be prevented from slipping between the two limiting members 431.
