[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type ones, with the treads mounted on the tracks and running continuously, commonly known as escalators or moving walkways. A fixed lifting device that serves specified floors. A vertical lift has a car that runs between at least two rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car facilitate passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving mode. According to speed, they can be divided into low-speed elevators, fast elevators and high-speed elevators. With the development of science and technology, elevators are also constantly improving and developing. Now elevators are mainly composed of traction systems, guide systems, cars, door systems, weight balance systems, electric traction systems, electrical control systems and safety protection systems. The door panels of elevators are usually made of stainless steel plates bent by a bending mechanism. However, there are more or less some problems in the application of current elevator bending machines.
