Description

Technical Field

[0001] This utility model belongs to the field of metal rolling technology, specifically a metal plate rolling device. Background Technology

[0002] Metal rolling is a metal processing technology that uses external force to compress and stretch metal materials between two rotating rolls, thereby changing their shape and size. The rotation of the rolls feeds the metal billet between them, and under the pressure of the rolls, the metal billet undergoes plastic deformation, reducing its thickness and increasing its length and width. During rolling, the internal grain structure of the metal changes, making its microstructure denser, thus improving its strength, toughness, and other mechanical properties. In existing metal rolling processes, rolling with a single roll easily leads to the metal sheet bending into an arc shape, making subsequent rolling difficult. Therefore, we propose a metal sheet rolling device. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4A metal sheet rolling apparatus includes two sets of auxiliary devices 100 and multiple sets of rolling devices 200. The left and right auxiliary devices 100 are arranged in a mirror image, and the upper and lower rolling devices 200 are arranged in a mirror image. Each auxiliary device 100 includes a first U-shaped plate 110. Two sets of first cylinders 120 are fixedly connected to the front and rear side walls of the first U-shaped plate 110. The telescopic ends of the two sets of first cylinders 120 are fixedly connected to second U-shaped plates 130. The opposite sides of the two sets of second U-shaped plates 130 rotate evenly. Multiple sets of first rotating rods 140 are connected, and a chain belt 150 is connected to the rear side of each set of first rotating rods 140. A sprocket is provided on the outer side of each first rotating rod 140, and the chain belt 150 is located outside the sprocket. A first motor 160 is fixedly installed on the front side of the second U-shaped plate 130. The transmission end of the first motor 160 is fixedly connected to the left first rotating rod 140. When the first cylinder 120 is activated, the second U-shaped plate 130 is driven to rise and fall through the first cylinder 120, and the first U-shaped plate 130 is driven to rise and fall through the second U-shaped plate 130. The height of the rotating rod 140 is adjusted to better coordinate with the rolling devices 200 on both sides when the workpiece is reciprocating and rolling. The first motor 160 is started, which drives the left first rotating rod 140 to rotate. The rotation of the left first rotating rod 140 drives the chain belt 150 to rotate, which in turn drives the other first rotating rods 140 to rotate. The rotation of the first rotating rods 140 causes the metal plate to move left and right for reciprocating edge rolling. The height of the first rotating rod 140 can be adjusted by the auxiliary device 100, which allows for better coordination with the rolling devices 200 on both sides when the workpiece is reciprocating and rolling. The upper side of the second U-shaped plate 130 is fixedly connected to the first auxiliary plate 131. The body of the first rotating rod 140 is provided with a groove. The upper side of the first auxiliary plate 131 is rotatably connected to the first rotating rod 140. The first auxiliary plate 131 provides auxiliary support for the first rotating rod 140, improving the stability of the device.

[0024] The lower rolling device 200 includes two sets of second cylinders 210. A third U-shaped plate 220 is fixedly connected to the telescopic ends of the two sets of second cylinders 210. A rolling roller 230 is rotatably connected to the upper side of the third U-shaped plate 220, and a second rotating rod 240 is rotatably connected to the lower side of the third U-shaped plate 220. A second motor 250 is fixedly connected to the rear side of the third U-shaped plate 220. The transmission end of the second motor 250 is fixedly connected to the second rotating rod 240. Starting the second motor 250 drives the second rotating rod 240 to rotate, which in turn compresses the rolling roller 230, causing it to rotate. The rotation of the rolling roller 230 then rolls the metal sheet. The second cylinders are then activated. 210, the second cylinder 210 drives the third U-shaped plate 220, and the height of the third U-shaped plate 220 is adjusted to adjust the height of the second rotating rod 240 and the calendering roller 230. This causes the distance between the two sets of calendering rollers 230 to be reduced in turn by the multiple calendering devices 200, thereby calendering the metal plate in turn. At the same time, the multiple calendering devices 200 calender the metal plate, reducing the possibility of the metal plate tilting as a whole and improving the stability of the device. By setting multiple calendering devices 200, the metal plate can be subjected to force at multiple points during the calendering process, thereby reducing the possibility of the metal plate tilting as a whole and making the reciprocating calendering process of the metal plate more stable, thus improving the stability of the device.

[0025] The third U-shaped plate 220 has grooves on both its front and rear sides. The calendering roller 230 has first connecting blocks 231 rotatably connected to both its front and rear sides. Fixed plates 221 are fixedly connected to both its front and rear sides. A spring 222 is fixedly connected to the lower side of the fixed plate 221, and the lower side of the spring 222 is connected to the first connecting block 231. A guide rod 232 is fixedly connected to the upper side of the first connecting block 231, and the upper side of the guide rod 232 passes through the body of the fixed plate 221. During use, the fixed plate 221 presses against the spring 222, causing the spring 222 to deform and generate elastic force that drives the first connecting block 231 to move forward. This causes the first connecting block 231 to move the calendering roller 230 closer to the second rotating rod 240, thereby allowing the second rotating rod 240 to... The calendering roller 230 is stably driven to rotate. The first connecting block 231 is limited by the guide rod 232, which improves the stability of the calendering roller 230. The calendering roller 230 has adjustable space by the cooperation of the fixing plate 221, spring 222 and the first connecting block 231. This allows the calendering roller 230 to always be close to the first rotating rod 140, while not generating much wear when not calendering, thus improving the stability of the device. Two sets of second auxiliary plates 223 are fixedly connected to the upper side of the third U-shaped plate 220. The second auxiliary plates 223 are provided with a guide angle on the side away from the third U-shaped plate 220. The second auxiliary plates 223 can be used to assist in limiting the metal plate, thus improving the stability of the device.

[0026] A lubricating fluid tank 300 is provided on the lower side of the lower rolling device 200. Multiple sets of water pumps 310 are installed on the upper side of the lubricating fluid tank 300. The water outlet of the water pump 310 is fixedly connected to multiple sets of first nozzles 320 and second nozzles 330 through metal hoses. The first nozzles 320 are installed on the lower side of the second auxiliary plate 223, and the second nozzles 330 are installed on the upper side of the upper second auxiliary plate 223. When the water pump 310 is started, it absorbs lubricating fluid and sprays it onto the upper and lower sides of the metal plate through the first nozzles 320 and the second nozzles 330, thereby improving the efficiency of subsequent rolling. The lubricating fluid that falls off the metal plate falls into the lubricating fluid tank 300 for collection. By setting up the lubricating fluid tank 300 and the water pump 310 to spray the lubricating fluid, the efficiency of subsequent rolling of the metal plate is improved.
