Description

Technical Field

[0001] The utility model relates to the technical field of metal plate shearing devices, and more specifically to a metal plate shearing and straightening device. Background Art

[0002] During the production process of metal sheets, some industries have certain requirements for the thickness and length of the metal sheets used. In order to meet the supply requirements of such metal sheet products, the produced metal sheets need to be cut to size. After processing and cutting, the metal sheets may tilt when transported along the conveyor belt. When the tilted metal sheet is unloaded, it will be stuck with the blanking roller due to its tilt angle and cannot fall smoothly. It needs to be manually adjusted. Even if the tilted metal sheet falls successfully, its blanking position is very crooked and needs to be manually rearranged and adjusted, which affects the processing efficiency.

[0003] After searching, it was found that the document with announcement number CN217913914U involves a straightening device for shearing metal plates. The device in the document can correct the metal plates that are transported after shearing. However, the device can only correct the inclination of the metal plates on the conveyor belt. However, when the metal plates are sheared, due to the residual stress of the metal plates in the manufacturing process, the stress will be released to a certain extent during shearing, resulting in curling of the cross section, causing one end of the metal plate to be slightly bent, which needs to be corrected. For this reason, we propose a metal plate shearing and straightening device. Utility Model Content
