[0002] Use bending methods to make products and enhance the strength of products. Improve the durability of products, reduce product processing time, and make products more solid, including but not limited to door panels, back panels, filing cabinets, kitchen utensils and other products. Electro-hydraulic bending machines and bending centers are commonly used for bending. Bending is often used in steel products industries, such as furniture, kitchen utensils, hardware and other industries.

[0003] When bending a sheet, the sheet is usually placed in a bending machine for bending. The rear stop finger is required to position the sheet at each bending position of the sheet to ensure the flatness and levelness of the bending surface. The rear stop finger of a conventional bending machine is only for a single type of bending product. For example, if the size of the sheet is changed or the bending product is changed, the lateral position of the rear stop finger needs to be manually adjusted, and the conventional rear stop finger has only a one-way fine-tuning function and only has the function of front and rear fine-tuning. During installation, due to the limitation of fine-tuning, the rear stop effect is not ideal, resulting in the sheet bending effect not meeting the requirements, and serious phenomena such as skewed bending surface occur. In order to achieve a stable parallel state between the sheet, the knife groove and the stop finger after the rear stop device is installed, the repeated replacement of the stop finger position, the re-calibration of the stop finger levelness, and the diversity of sheet bending are avoided, and a new type of rear stop device for a bending machine is proposed to improve this problem.
