A steel plate shearing device and method for metal rolling processing

Abstract

The present invention relates to the technical field of shearing devices, and in particular to a steel plate shearing device and method for metal rolling processing. An auxiliary pressing plate portion is provided, which positions the steel plate to be cut by enabling a pressing block to be tightly pressed against the upper end of the steel plate. Uniform point pressure can be provided by evenly arranged point pressure components to ensure that the steel plate will not shift when being cut, and the cutting knife seam is ensured to be neat, thereby ensuring the cutting quality of the cut steel plate. The cut small piece of steel plate will be conveyed to the right as the transmission roller runs again, and the debris generated during cutting will fall onto the inclined slide during the process of conveying to the right. When the device is stopped for rest, the electrically controlled mounting slider slides to the left along the mounting slot, so that the sweeping portion scrapes and sweeps the debris on the inclined slide, and the debris falls into the containing portion through the blanking through hole for temporary collection. The automated chip cleaning process can centrally clean the debris dropped during the conveying process and then completely remove it to avoid contaminating the device.

Description

Technical Field

[0001] The invention relates to the technical field of shearing devices, and in particular to a steel plate shearing device and method for metal rolling processing. Background Art

[0002] The steel plates generally used for metal rolling processing are obtained by uncoiling and leveling the metal coils and then cutting them.

[0003] The existing technology has the following main problems when cutting long steel plates after leveling: 1. The shearing device uses a hydraulic system to push the blade to cut quickly to achieve plate cutting, but the blade has a large shear force at the action part, which will cause the steel plate to move during the cutting process, resulting in uneven incisions, and the impact of the cutting will cause the plate to stretch to a certain extent, affecting the quality of the plate.

[0004] 2. Metal debris will be generated when cutting steel plates. As the steel plates move, some debris adhering to the cut edges of the steel plates will fall off. The debris falling on the moving device will contaminate the machine. It is inconvenient and difficult to clean them manually.

After pushing, the mounting slide block 66 is at the leftmost side in the mounting slide slot 65, and the mounting connecting rod 671 is rotated by the motor 2 672 to make the mounting connecting rod 671 rotate 90° first, and then the mounting slide block 66 quickly slides to the upper right to the initial position along the mounting slide slot 65, and then continues to rotate 90° to make the brush bristles 676 face the end face of the inclined slide table 64, and then moves to the lower left to thoroughly sweep away the fine debris, and the debris swept into the loading frame 622 can be moved out and dumped out by the push-pull handle 623; the spring 2 677 is connected to the sliding brush plate 675, so that the bristles 676 can adaptively fit and brush the inclined slide table 64 to ensure thorough cleaning.

[0053] In addition, the present invention also provides a steel plate shearing method for metal rolling processing, comprising the following steps:

[0054] S1. Flattening coils: Unroll and flatten the metal coils used for metal rolling processing to obtain horizontal steel plates to be cut.

[0055] S2. Calibration and positioning: The leveled steel plate enters the conveying unit 5, is intermittently positioned and transported by the conveying unit 5, and is centered and calibrated before being sent to the cutting unit 4.

[0056] S3. Precision cutting: The steel plate is first pressed and positioned by the cutting unit 4, and then quickly cut to ensure a smooth cut.

[0057] S4, debris collection: The debris dropped during transportation is centrally processed by the debris cleaning unit 6.

[0058] S5, collecting plates: the cut small pieces of steel plates are intermittently transported to the right by the conveying unit 5 for sorting and standby use.

[0059] The working principle of the present invention is as follows: the rotational force is provided by the motor 54, and then the rotational force is synchronously transmitted to each transmission roller 51 through the pulley member 52 by the transmission belt 53, so that the transmission roller 51 rotates synchronously at a uniform speed, and the steel plate transmitted from the left is transported to the right by the rotating transmission roller 51. When the steel plate enters above the roller group on the left, the steel plate is adjusted to the center front and back by the centering calibration part 55, so that the steel plate that is then transported to the upper end of the carrying cutting table 44 for cutting remains straight and centered. When the right end of the steel plate contacts the intermittent stop part 56, the motor 54 stops rotating intermittently. At this time, the steel plate below is firmly pressed by the auxiliary pressure plate part 43, so that the steel plate will not move when subjected to a sudden downward cutting force. At the same time, the steel plate is cut. Keeping it in a straight state makes it easier to cut it off in one go, so as to obtain a neater incision. The small piece of steel plate cut off will be transported to the right as the transmission roller 51 runs again; the above cutting work is carried out continuously to ensure cutting efficiency; the debris generated during cutting will fall onto the inclined slide 64 during the process of being transported to the right, and when the device is shut down for rest, the electrically controlled mounting slider 66 slides to the left along the mounting slide groove 65, so that the sweeping part 67 scrapes and sweeps the debris on the inclined slide 64, and the debris will fall from the blanking hole 61 into the containing part 62 for temporary collection and storage; the inclined slide 64 is arranged to facilitate sweeping away the debris, and the matching guide plate 68 can prevent the debris from entering the mounting slide groove 65, and can also guide the debris to fall on the inclined slide 64 or the blanking hole 61.
