Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of punch bending integrated machine, in particular to a plate punch bending integrated forming device based on mechanical arm transfer. BACKGROUND

[0002] In the manufacturing industry, the processing of plate material usually involves multiple processes such as punching and bending, which are often carried out on different equipment. Manual or simple conveying devices are needed to transport the plate material to the punching equipment for punching forming, and then the punched plate material is transferred to the bending equipment for bending processing by manual or other transportation methods. This makes the plate processing time-consuming, resulting in low production efficiency.

[0003] Because the connection between different processes requires manual participation, the plate material is placed on the conveying mechanism or manually transported, and the plate material is transferred from the punching processing equipment to the bending processing equipment. This results in many breakpoints in the production process, and when the plate material is transferred between different equipment, there is a long waiting time, which reduces the smoothness and continuity of the entire production process. These devices need to be operated, supervised and adjusted manually, which greatly increases the labor cost. The speed and efficiency of manual operation are limited, and it is difficult to meet the production needs of large-scale and high efficiency. When the plate material is transferred to the punching equipment or the bending equipment, the instability of personnel operation and individual differences make it difficult for manual operation to ensure the accurate placement of the plate material, which may cause position deviation and affect the processing quality and production progress, and may also produce defective products.
