Description

Technical Field

[0001] The present invention relates to the technical field of plate rolling machines, and particularly relates to a plate rolling machine with a unilateral pre-bending function. Background Art

[0002] A plate rolling machine is a device that uses working rolls to bend sheet materials. When a steel plate is bent into an unclosed steel ring by a plate rolling machine, in order to facilitate unloading, it is necessary to withdraw the rolling rolls from inside the ring, and then smoothly unload the steel ring. At the same time, the steel ring is heavy, and it is difficult to unload it manually. It is necessary to use a unloading structure to unload the steel ring. For example, the Chinese utility model patent with the patent publication number CN218798374U solves the problem that it is difficult to unload manually and it is necessary to use a unloading structure to unload the steel ring.

[0037] Embodiment Three

[0038] Please refer to Figure 1 - Figure 2 As shown, on the basis of the first embodiment and the second embodiment, the blanking assembly 6 includes a second cleaning brush 73 slidably mounted on the inner bottom of the base 1. A pull rod 76 is fixedly installed on the side of the second cleaning brush 73 away from the base 1. The engagement of the pull rod 76 on the conveying table 51 plays a role in limiting and stabilizing the second cleaning brush 73. A groove is formed on the side of the conveying table 51 away from the base 1. The pull rod 76 is installed in the groove, which plays a role in limiting and stabilizing the second cleaning brush 73. A telescopic rod 74 and a spring 75 are fixedly installed on the side of the conveying table 51 close to the fixing plate 55. The telescopic rod 74 is fixedly installed with a mounting plate 71 on the side away from the conveying table 51. A first cleaning brush 72 is fixedly installed on the side of the mounting plate 71 close to the second cleaning brush 73. The cooperation of the second cleaning brush 73 and the first cleaning brush 72 plays a role in cleaning the steel plate. The other end of the spring 75 is fixedly installed on the mounting plate 71. The spring 75 is nested on the outer surface of the telescopic rod 74, which plays a role in driving the mounting plate 71 to elastically reset, facilitating the mounting plate 71 to drive the first cleaning brush 72 to elastically reset and facilitating the cleaning operation. Pulling the pull rod 76 to drive the second cleaning brush 73 facilitates scraping out the dust after cleaning, facilitating the cleaning of the dust, and is beneficial to improving the cleaning ability of the device.

[0039] Working principle of the present invention: When using the device, first start the adjusting cylinder 9, so that the adjusting cylinder 9 drives the slider 10 to slide in the chute 8, and at the same time the slider 10 drives the upper curling roller 3 to adjust the distance between the upper curling roller 3 and the lower curling roller 2. Then start the first motor 12 and the second motor 13, so that the output ends of the first motor 12 and the second motor 13 drive the upper curling roller 3 and the lower curling roller 2 to rotate, and at the same time the rotation directions of the upper curling roller 3 and the lower curling roller 2 are opposite, which is convenient for rotating the rolled plate. Place the steel plate on the conveying roller 57 and convey it to the pre-bending roller 56. Then start the first electric telescopic rod 52, so that the first electric telescopic rod 52 drives the pre-bending roller 56 and the steel plate to move upward through the mounting block 53 towards the two limiting rollers 54, which is convenient for bending. After bending, contract the first electric telescopic rod 52, so that the steel plate is conveyed on the pre-bending roller 56 towards the lower curling roller 2, and at the same time the steel plate passes through between the first cleaning brush 72 and the second cleaning brush 73 to clean the dust. At the same time, the steel plate drives the mounting plate 71 to move upward through the first cleaning brush 72, and at the same time the mounting plate 71 stretches the telescopic rod 74 and the spring 75, so that the telescopic rod 74 and the spring 75 are in a stretched state. When the steel plate leaves the second cleaning brush 73 and the first cleaning brush 72 and enters between the lower curling roller 2 and the upper curling roller 3, the spring 75 drives the mounting plate 71 to elastically reset, so that the steel plate timely adjusts the rotation direction of the steel plate under the action of the rotating column 63 and the guide plate 64 for the curling operation. After the curling is completed, contract the adjusting cylinder 9 to make the upper curling roller 3 move upward. Then start the electric telescopic plate to rotate and contract the limiting plate 4 from the base 1. Then start the second electric telescopic rod 61, so that the second electric telescopic rod 61 drives the guide block 62 to lift the rolled plate. Then start the driving motor 68, so that the output end of the driving motor 68 drives the reciprocating screw 65 to rotate, so that the reciprocating screw 65 drives the moving block 66 to slide in the moving through hole 610. At the same time, start the blanking column 67 to move upward to fit with the steel plate, and at the same time the blanking column 67 drives the rolled plate on the guide block 62 under the drive of the moving block 66, and at the same time the curling has a sliding efficiency on the rotating column 63 and the pulley 14, which is convenient for the blanking operation.
