Description

Technical Field

[0001] The utility model relates to the field of steel structure processing equipment, in particular to an automated rolling device for assembled building steel structures. Background Art

[0002] The automated rolling device for prefabricated building steel structures is a key equipment for forming steel structure components. It has the advantages of high production efficiency and stable forming quality. It is widely used in the processing of prefabricated building steel structures, helping to improve the level of industrialized production of components and shorten the construction period.

[0003] A Chinese patent discloses an embossed steel roller group (authorization announcement number CN220594230U), which includes a base, a first motor and a second motor. A concave support roller frame is provided on the top of the base, and the top and bottom of the inner side of the concave support roller frame are respectively connected to the pressure roller and the embossing roller through a rotating shaft. The outer surface of both sides of the embossing roller is evenly provided with first disassembly screw holes, and the outer surface of the embossing roller is surrounded by a first printing sheet. Second disassembly screw holes are provided on both sides of the surface of the first printing sheet corresponding to the position of the first disassembly screw holes. This patented technology can facilitate disassembly and replacement, thereby improving the convenience of replacing the pressure roller. However, when the device rolls the metal profile, the metal profile is subjected to extrusion and friction, which causes stress concentration and cracks in the metal profile, making it easy for debris to appear on its surface. In the process of mutual friction with the pressure roller, the debris is transferred and adhered to the surface of the pressure roller, which will cause pits and scratches on the surface of the metal profile rolled subsequently, affecting product quality and mechanical properties, and accelerating the wear of the pressure roller and key components of the equipment, increasing the risk of failure.

[0004] Therefore, the present invention provides an automated rolling device for assembled building steel structures to solve the above-mentioned problems. Utility Model Content

[0010] As a further solution of the present invention, there are multiple adsorption plates that are symmetrically and evenly distributed on the outside of the rotating tube. The inner cavity of the rotating tube is fixedly installed with multiple driving structures for promoting the expansion of the adsorption plates. The driving structures drive the multiple adsorption plates to move synchronously to ensure that the adsorption plates are always in contact with the pressure rollers to adapt to pressure rollers of different sizes.

[0011] As a further solution of the present invention, each of the driving structures includes an airbag, which is fixedly installed in the inner cavity of the rotating tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When the utility model is in use, the cleaning structure adopts a combination of airbag drive and electromagnetic adsorption, so that the adsorption plate and the expansion plate can adapt to the different sizes of pressure rollers, and can also achieve comprehensive and efficient adsorption of metal debris.

[0027] The inner cavities of the two sets of pressure rollers 5 are rotatably connected with the rotating shafts 4 for supporting the pressure rollers 5. The two ends of the two sets of rotating shafts 4 are respectively passed through the rolling mill frame 2 and the lifting roller frame 3, and the two sets of rotating shafts 4 are installed and fixed by bolts. The two sets of pressure rollers 5 are both attached to the side away from each other with a cleaning structure 8, which is used to remove metal debris generated during the rolling process.

[0028] Specifically, a main control box 9 for controlling the overall automatic operation of the control device is fixedly installed on the top surface of the rolling mill frame 2, and fixed plates 10 are fixedly installed on both sides of the rolling mill frame 2 and the lifting roller frame 3. An electric rod 11 for controlling the up and down movement of the lifting roller frame 3 is fixedly installed between the two sets of fixed plates 10, and a sliding rod 12 is fixedly installed at the bottom end of the lifting roller frame 3, and the bottom end of the sliding rod 12 is slidably inserted into the inner cavity of the rolling mill frame 2. When working, the electric rod 11 drives the lifting roller frame 3 to rise and fall smoothly through precise telescopic movements, and flexibly adjusts the spacing between the two sets of pressure rollers 5 to adapt to metal profiles of different thicknesses and specifications, meet diversified production needs, and improve the versatility of equipment. At the same time, the cooperation of the sliding rod 12 and the rolling mill frame 2 effectively limits the shaking and deviation of the lifting roller frame 3, ensures the accuracy and stability of the adjustment of the spacing between the pressure rollers 5, avoids problems such as uneven rolling surface and dimensional deviation of the metal profile due to the shaking of the lifting roller frame 3, and ensures product quality.

[0029] See also Figures 2 to 6 The cleaning structure 8 includes a fixed shaft 801. There are two groups of fixed shafts 801, and the two groups of fixed shafts 801 are fixedly connected to the inner walls of the rolling mill frame 2 and the lifting roller frame 3 respectively. The outer walls of the two groups of fixed shafts 801 are provided with a rotating tube 802 through a bearing rotation sleeve. The outer wall of the rotating tube 802 is installed with an adsorption plate 803 for adsorbing metal debris, and the adsorption plate 803 is in contact with the outer wall of the pressure roller 5.

[0030] There are multiple adsorption plates 803 that are symmetrically and evenly distributed on the outside of the rotating tube 802. The inner cavity of the rotating tube 802 is fixedly installed with multiple driving structures for pushing the adsorption plates 803 to expand. The driving structures drive the multiple adsorption plates 803 to move synchronously, ensuring that the adsorption plates 803 always fit the pressure roller 5 to adapt to pressure rollers 5 of different sizes.

[0031] See also Figure 6 Each driving structure includes an airbag 804, which is fixedly installed in the inner cavity of the rotating tube 802. The upper and lower ends of the airbag 804 are fixedly connected to moving parts 805. The outer wall of each moving part 805 is fixedly connected to multiple transmission rods 806 for pushing the adsorption plate 803 to move through a pin, and the transmission rods 806 are rotatably connected to the adsorption plate 803 through a pin.

[0032] Specifically, the inner cavity of the rotating tube 802 is provided with a moving groove for providing a moving member 805 to move up and down, and the moving member 805 is slidably located in the moving groove. A fixing ring 807 for fixing the airbag 804 is fixedly installed on the inner wall of the rotating tube 802. The fixing ring 807 is fixedly sleeved on the outer wall of the airbag 804, and the fixing ring 807 is located at the center of the airbag 804, so that when the airbag 804 expands or contracts, the two groups of moving members 805 are driven to achieve a synchronous movement effect.

[0033] More specifically, a plurality of fixed rods 808 are fixedly installed on the outside of the airbag 804, and the upper and lower ends of the fixed rods 808 are fixedly connected to the inner wall of the rotating tube 802. A storage spring 809 is fixedly installed between the two groups of moving parts 805, and the storage spring 809 is sleeved on the outside of the fixed rod 808. The storage spring 809 pulls the two groups of moving parts 805 closer to each other, driving the transmission rod 806 to drive the adsorption plate 803 to expand outward to fit the outer surface of the pressure roller 5. When the pressure roller 5 rotates, the adsorption plate 803 can promptly remove debris and impurities adhered to the surface, preventing the debris from scratching the metal profile or aggravating the wear of the pressure roller 5, thereby ensuring the surface quality of the metal profile rolling and the stability of the equipment operation. At the same time, the elastic characteristics of the storage spring 809 provide the adsorption plate 803 with a certain buffering capacity, which can adapt to pressure rollers 5 of different diameters, thereby improving the versatility and reliability of the cleaning structure.

[0034] More specifically, the inner cavity of the rotating tube 802 is fixedly connected to the gas pipe 810, and the gas pipe 810 passes through each air bag 804 in turn and is connected to the inner cavity of the air bag 804. The outer wall of the rolling mill frame 2 is fixedly installed with an air pump 811 for providing gas, and the gas delivery end of the air pump 811 is fixedly connected to the gas pipe 810.

[0035] See also Figure 5An expansion plate 812 is slidably connected between each two adsorption plates 803, and is used to ensure full coverage of the cleaning structure 8. Each two expansion plates 812 are fixedly connected by a tension spring 817. The adsorption plates 803 and the expansion plates 812 are fixedly connected to an electromagnetic tube 813 for providing adsorption force on one side close to the rotating tube 802 through a connector.

[0036] Specifically, the inner cavity of each adsorption plate 803 is provided with a sliding groove for providing sliding for the expansion plate 812, and the expansion plate 812 is located in the sliding groove. Both sides of each adsorption plate 803 are provided with inclined surfaces to guide the metal debris to slide down and avoid accumulation. The inclined angle allows the adsorbed metal debris to flow in a directional manner under the action of gravity, which is convenient for centralized collection.

[0037] More specifically, the adsorption plate 803 and the expansion plate 812 are both made of low-carbon steel, which utilizes its own magnetic conductivity to efficiently conduct the magnetic field of the electromagnetic tube 813. The surface of the pressure roller 5 is coated with a non-magnetic conductive layer to reduce interference with the magnetic field.

[0038] See also Figure 3 、 Figure 7 A collection box 814 for collecting metal debris is installed on one side of the adsorption plate 803. A cleaning brush 815 is fixedly connected to the top of the collection box 814. The cleaning brush 815 is in contact with the surface of the adsorption plate 803 and is used to scrape off the metal debris adsorbed on the surface of the adsorption plate 803.

[0039] Specifically, an extension plate is provided at one end of the collection box 814 close to the adsorption plate 803, and the extension plate has a certain inclination angle, which is used to collect and guide metal debris into the collection box 814. Both ends of the collection box 814 are fixedly connected with moving blocks 816 for driving the movement thereof, and the inner walls of the rolling mill frame 2 and the lifting roller frame 3 are provided with moving grooves for providing movement of the moving block 816, and the moving block 816 is located in the moving groove. A telescopic spring 818 is fixedly connected to one side of the moving block 816, and the telescopic spring 818 pushes the moving block 816 to drive the collection box 814 to move, so that the collection box 814 is close to and close to the adsorption plate 803.

[0040] More specifically, conductive plates 819 are fixedly installed on the inner walls of the rolling mill frame 2 and the lifting roller frame 3, and both ends of the electromagnetic tube 813 are in contact with the conductive plates 819. The conductive plates 819 are set to be semi-arc-shaped. When the electromagnetic tube 813 continues to rotate around the rotating tube 802, when the electromagnetic tube 813 is separated from the conductive plate 819, it can be disconnected in time to energize the electromagnetic tube 813, thereby causing the corresponding set of adsorption plates 803 or expansion plates 812 to lose their adsorption force, allowing the metal debris on their surface to fall into the collection box 814.

[0041] The working principle of this utility model is:

[0042] When the device of the present invention is in use, the metal profile is fed into the device via the feed roller 7, and the main control box 9 controls the electric rod 11 to extend and retract, driving the lifting roller frame 3 to move up and down along the sliding rod 12 on the rolling mill frame 2, and adjusting the distance between the two sets of pressure rollers 5 to adapt to the thickness of the metal profile. During the movement of the metal profile, the pressure rollers 5 are driven to rotate, and the roll forming is completed under the extrusion of the pressure rollers 5;

[0043] At the same time, the air pump 811 pumps air into the air pipe 810, causing the airbag 804 to contract, driving the two sets of moving parts 805 to move closer together. The transmission rod 806 drives the adsorption plate 803 to expand and fit the pressure roller 5. Moreover, the adsorption plate 803 and the expansion plate 812 absorb the metal debris on the surface of the pressure roller 5 under the action of the magnetic force generated by the electromagnetic tube 813.

[0044] When the adsorption plate 803 and the expansion plate 812 rotate with the rotating tube 802, and the electromagnetic tube 813 is separated from the conductive plate 819, the electromagnetic tube 813 is powered off and loses its magnetism, and the metal debris falls into the collection box 814 under gravity. The cleaning brush 815 on the top of the collection box 814 simultaneously scrapes off the residual metal debris on the surface of the adsorption plate 803, realizing a metal debris cleaning cycle, effectively ensuring the quality of the rolled metal profile, and extending the service life of the pressure roller 5.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
