Abstract
Description
Technical Field
[0001] This application relates to the field of plate rolling technology, specifically to a plate rolling machine. Background Technology
[0002] A plate rolling machine is a processing device that rolls metal sheets into the desired circular shape. It operates on the principle of three points forming a circle. A three-roll plate rolling machine consists of two lower rollers rotating in the same direction and an upper roller with adjustable height. During operation, the steel plate is manually placed into the gap between the upper and lower rollers, and is rolled in by friction, thus completing the rolling process. However, in actual operation, it has been found that when the steel plate is rolled into a cylindrical shape, misalignment of the seams affects subsequent welding or even prevents welding, resulting in scrap. This phenomenon occurs because the steel plate is laterally skewed during loading, and manual operation makes it difficult to ensure complete alignment of the steel plate during loading. Furthermore, the alignment adjustment process is time-consuming and labor-intensive, resulting in low work efficiency, and urgently needs improvement. Utility Model Content

[0021] See attached document Figure 1This application provides a plate rolling machine, including a plate rolling machine body 100, a feeding platform 200, a first centering mechanism 300, a second centering mechanism 400, and a pushing mechanism 700. The plate rolling machine body 100 is used to complete the rolling and forming of plates. The feeding platform 200 is disposed on the feeding side of the plate rolling machine body 100 and is used to transport the steel plate to be rolled to the plate rolling machine body 100. The first centering mechanism 300 is fixedly disposed on the feeding platform 200, and the second centering mechanism 400 is slidably disposed on the feeding platform 200. The distance between the first centering mechanism 300 and the second centering mechanism 400 is adjustable so as to center and align steel plates of different lengths on the feeding platform 200. The pushing mechanism 700 is disposed on the feeding platform 200 and is used to push the aligned steel plate into the plate rolling machine body 100.
[0022] In the above embodiments, it can be understood that the first centering mechanism 300 and the second centering structure are used to center and align plates of different lengths on the feeding platform 200, and then the aligning plates are fed between the upper roller 101 and the lower roller 102 by the pushing mechanism 700. Thus, the steel plate is in an upright state when feeding, and no lateral tilting occurs during the feeding process, reducing the risk of the steel plate rolling out a protruding tip and the seam misalignment, which helps to facilitate the direct welding of the steel plate in the later stage.
[0023] In the above, the main body 100 of the plate rolling machine adopts an innovative design. Figure 3 The roller universal plate rolling machine includes a pair of lower rollers 102 and an upper roller 101. The steel plate is placed between the upper roller 101 and the lower roller 102. The steel plate is rolled between the upper roller 101 and the lower roller 102 by the rotation of the rollers and the friction. The tube plate machine is an existing mature equipment and will not be described in detail here.
[0024] In one embodiment, such as Figures 1 to 5 As shown, the feeding platform 200 includes a platform support 201 and a feeding roller 202 disposed on the platform support 201. The platform support 201 is supported on the bottom surface by support legs, and the feeding roller 202 is rotatably mounted on the platform support 201.
[0025] In the above embodiment, the steel plate to be rolled is conveyed by a rotating feeding roller 202, which has low friction and makes feeding more labor-saving.
[0026] like Figure 1 and Figure 4As shown, the first centering mechanism 300 is fixedly installed on one end of the feeding platform 200 near the main body 100 of the plate rolling machine. The first centering mechanism 300 includes a first bracket 301, a first centering motor 302, a first lead screw shaft 303, a first guide rod shaft, a first centering slider 304, and a first centering lever 305. The first bracket 301 is a U-shaped frame, which is fixedly installed across the bottom of the platform bracket 201 along the radial direction of the platform bracket 201. The first centering motor 302 is fixedly installed on one side of the outer surface of the first bracket 301. The first lead screw shaft 303... 03 and the first guide rod shaft are rotatably mounted in the first bracket 301 along the radial direction via bearings, and the two are arranged parallel to each other. The first lead screw shaft 303 is connected to the first centering motor 302 via a coupling, and the first lead screw shaft 303 has threads in opposite directions symmetrically arranged on both sides of its center. The first centering sliders 304 are respectively arranged at both ends of the first lead screw shaft 303 in a threaded manner, and the first centering sliders 304 are provided with first centering levers 305. There are multiple first centering levers 305, which are arranged between adjacent feeding rollers 202.
[0027] Continue as Figures 1 to 3 As shown, the second centering mechanism 400 is slidably disposed on the side of the feeding platform 200 away from the main body 100 of the plate rolling machine. The second centering mechanism 400 includes a second bracket 401, a second centering motor 402, a second centering lead screw shaft 403, a second centering guide shaft 404, a second centering slider 405, and a second centering lever 406. The outer surface of the platform bracket 201 is axially provided with a T-shaped guide rail 500. The second bracket 401 is radially spanned across the bottom of the platform bracket 201 and maintains a sliding fit with the T-shaped guide rail 500. Bolts 408 are provided on the outer surface of the second bracket 401. By screwing the bolts 408 outwards, the second bracket 401 is tightened to any position on the T-shaped guide rail 500. The second centering motor 402 is fixedly disposed on the outer surface of the second bracket 401. The two centering lead screw shafts 403 and the second guide shaft are radially rotatably mounted in the second bracket 401, and the two remain parallel. The second centering lead screw shaft 403 is connected to the second centering motor 402 through a coupling. The second lead screw shaft has symmetrical threads in opposite directions on both sides of its center. The second centering sliders 405 are respectively mounted at both ends of the second lead screw shaft. The second centering sliders 405 are equipped with retractable second centering levers 406. There are multiple second centering levers 406, which are arranged between adjacent feeding rollers 202.
[0028] It is conceivable that after placing the steel plate to be rolled on the feeding platform 200, it is difficult to ensure that the steel plate to be rolled is accurately positioned on the central axis of the feeding platform 200 every time. Therefore, in the above embodiment, according to the length of the steel plate to be rolled, the second centering mechanism 400 is moved closer to the tail of the steel plate to be rolled, while the first centering mechanism 300 is located at the head of the steel plate to be rolled. Then, by activating the first centering motor 302 and the second centering motor 402 respectively, the first centering slider 304 and the second centering slider 405 are moved closer along the first centering screw shaft and the second centering screw shaft 403 respectively. Thus, the head and tail of the steel plate to be rolled are aligned by the centering lever, so that the steel plate to be rolled is accurately positioned on the central axis of the feeding platform 200, ensuring that the steel plate to be rolled is not skewed during feeding.
[0029] To prevent the second centering lever 406 from being blocked by the feeding roller 202, thus preventing the second centering mechanism 400 from moving, in a preferred embodiment, such as... Figure 2 and Figure 6 As shown, the second centering lever 406 includes multiple interlocking rods, which are locked together by spring pins 407.
[0030] It can be imagined that by retracting the second centering lever 406 through the telescopic structure, the second centering lever 406 is lower than the bottom of the feeding roller 202, thereby enabling the second support 401 to move over the obstruction of the feeding roller 202. This allows the distance between the first centering mechanism 300 and the second centering mechanism 400 to be adjusted according to the length of the steel plate to be rolled.
[0031] In a preferred embodiment, such as Figure 1 and Figure 5 As shown, the pushing mechanism 700 includes a sliding bracket 701, a top-pressing cylinder 702, a fixed bracket 704, and a booster cylinder 705. Guide rails 600 are provided on both outer sides of the platform bracket 201. The sliding bracket 701 is radially mounted across the top of the platform bracket 201 and maintains a sliding fit with it. The top-pressing cylinder 702 is vertically mounted on the sliding bracket 701, with its output end facing towards the feeding roller 202 and having a pressure plate 703 at its end. The fixed bracket 704 is radially mounted across the top of the platform bracket 201 and is fixedly mounted thereon, further away from the main body 100 of the plate rolling machine than the movable bracket. The booster cylinder 705 is mounted on the fixed bracket 704, and its output end is fixedly connected to the sliding bracket 701.
[0032] As can be imagined, in this embodiment, after the steel plate is aligned by the first alignment mechanism 300 and the second alignment mechanism 400, the top pressure cylinder 702 extends to drive the pressure plate 703 to press down on the steel plate, and the booster cylinder 705 pushes the moving bracket to move along the feeding platform 200. Thus, the friction causes the steel plate to move along the surface of the feeding roller 202 and be fed between the upper roller 101 and the lower roller 102. Therefore, it is not necessary to manually place the steel plate between the upper roller 101 and the lower roller 102, ensuring that the steel plate is not skewed when feeding.
[0033] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
