Description

TECHNICAL FIELD

[0001] The present application relates to the field of door panel processing, in particular to a door panel production line. BACKGROUND

[0002] The elevator door panel is a key component in the elevator system that directly faces passengers or goods and constitutes the entrance and exit of the elevator. It not only serves as a physical barrier between the elevator car and the landing (floor platform), but also plays multiple roles such as safety protection, space separation, aesthetic decoration, and functional integration. The elevator door panel is a movable panel installed at the entrance of the elevator car and the landing, usually composed of two or more doors, which can be opened and closed through a mechanical or electric drive system. Its core functions include safety isolation to prevent passengers or goods from accidentally falling into the shaft during elevator operation, space control to connect the car and the landing by opening the door panel when the elevator stops at a floor, and functional carrier to integrate sensors, indicator lights, locks, and other devices to support safety protection and intelligent operation.

[0003] The door panel production line is a production line for producing elevator door panels, which is a key link in elevator manufacturing.

The plate is fed from the feeding to the punching, bending, welding, spot welding, and material receiving, making the entire production process of the elevator door panel automated, which greatly improves the work efficiency and eliminates the need for manual handling of obstacles. However, the above-mentioned application only uses a mechanical hand to transfer the door panel in the punching machine and bending machine, etc. to realize the production and processing of the door panel. However, the punching machine and bending machine are existing technologies, and the door panel single hole relies on a punching device for single punching forming in the existing technology, which takes a long time and has low punching quality, and is prone to deviation and other situations. At the same time, the bending angle of the existing technology is fixed, and different bending angles of the door panel require different bending machines or bending heads, which reduces the bending efficiency and affects the overall production and processing efficiency of the door panel.
