Description

Technical Field

[0001] This utility model belongs to the field of steel cabinet manufacturing technology, specifically relating to a corner bending device for producing steel cabinets. Background Technology

[0002] Steel cabinets are used to store documents and materials. They are commonly used in offices, archives, document rooms, storage rooms, or personal studies. File cabinets are mainly classified by material into plastic file cabinets, steel file cabinets, and wooden file cabinets. Steel file cabinets are made of cold-rolled steel plates through a complete and precise manufacturing process. During the steel plate processing, corner bending devices are usually used to bend the plates to improve processing efficiency.

[0003] In existing related technologies, during the bending process, the steel plate needs to be loaded and positioned before it can be bent by hydraulic cylinders, and then the next steel plate can be processed after bending. This makes it impossible to effectively and quickly bend and adjust the steel plate. Therefore, there is an urgent need to design a corner bending device for producing steel cabinets to solve these problems. Utility Model Content
