Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, specifically a steel plate bending device that facilitates adjustment of the bending angle. Background Technology

[0002] Bending machines are important equipment in the sheet metal industry for bending and forming workpieces. Their function is to press steel plates into parts of various shapes according to process requirements. Bending machines are divided into manual bending machines, hydraulic bending machines, and CNC bending machines. Manual bending machines are further divided into mechanical manual bending machines and electric manual bending machines.

[0003] According to Chinese patent document CN220970436U, a bending structure that facilitates adjustment of bending angle is disclosed. By setting the adjustment components, when it is necessary to adjust the angle of the sheet metal during bending, the screws in all the worm gears can rotate synchronously through the worm gear. The screw sleeve can then drive the support plate to move, thereby pushing and pulling the limit plate through the slide bar on the support rod to adjust the included angle between the rotating seats. This allows the pressure head to form different angles when pressing the sheet metal, which helps to improve the application range of the equipment.

[0004] However, in the aforementioned device, the ends of the two rotating seats that are close to each other are semi-circular, which results in an irregular indentation at the bottom of the angle formed by the two rotating seats. This indentation affects the bending of the steel plate, causing the bending position of the steel plate to deform downwards along this irregular indentation. Therefore, a steel plate bending device that facilitates adjustment of the bending angle is proposed. Utility Model Content
