Since the elevator manufacturing process involves a large amount of metal sheet processing, including door panels, frames, shells, brackets, etc., the quality, precision and production efficiency of sheet metal parts directly affect the overall performance and safety of the elevator. Through the flexible manufacturing system, it is possible to flexibly respond to different batches and diversified product requirements, greatly improving production efficiency and flexibility.

 

The acceleration of urbanization and the increase in high-rise buildings, coupled with updates and maintenance, have provided impetus for the stable growth of elevator demand. The continuous growth of market demand has also driven the sheet metal processing industry for components such as elevator cars, door panels, and control cabinets.

 

The elevator industry, as a typical representative of discrete manufacturing, highly relies on fine division of labor and collaboration in its production process. CNC, with its profound industry insights and technological innovation, has created a flexible production line for elevator door panels in the elevator industry, solving the pain points in traditional production models.

 

In the production process of sheet metal products, the wall and door panel, as key components, need to go through a series of complex and rigorous processes: from the initial stamping and cutting, to bending and forming, and then to the unique processing of the door panel, each step directly affects the final performance and appearance of the product.

  

2. Comparison: elevator flexible production and traditional production mode


Under the traditional production mode, these processes are often dispersed in different work areas and carried out using assembly line operations. This model has improved production efficiency to some extent, but there are also drawbacks.

 

The circulation of raw materials, semi-finished products, and finished products on the production line occupies a large amount of space, increasing warehousing and logistics costs

 

High human involvement and potential safety hazards, such as injury accidents caused by improper operation and scattered operations affecting product quality

 

The variety of products, large batch sizes, and frequent switching of production lines have reduced production efficiency and increased management difficulty and costs

 

The CNC flexible processing production line integrates a three-dimensional sheet metal storage system, laser cutting, sheet metal bending, etc., realizing automatic loading of raw materials to the exchange table and automatic stacking of finished products to the pallet, digital operation, saving time and safe handling. Effectively solves the problem of wasting time on manual loading or driving, forklift loading, etc., greatly saving labor costs and reducing safety hazards.
