Moreover, each structural part is made by sheet metal bending, which is also convenient for connecting each structural part to each other, saving the assembly time of the interlocking device 1000, thereby improving the efficiency of producing the interlocking device 1000.

[0035] Sheet metal bending, that is, the bending and forming of metal sheets is carried out on a plate bending machine. The workpiece to be formed is placed on the plate bending machine, the brake shoe is lifted by a lifting lever, the workpiece slides to the appropriate position, and then the brake shoe is lowered onto the workpiece to be formed. The bending of the metal is achieved by applying force to the bending lever on the plate bending machine. Sheet metal bending can reduce material waste, save energy, reduce pollution emissions, optimize the production process, and improve product quality.

[0036] Sheet metal bending is the process of bending metal sheets into the desired shape. It can minimize the waste of materials such as cutting and welding while ensuring the quality of the workpiece. This can not only reduce the procurement cost of materials, but also shorten the production process and reduce the scrap rate, contributing to environmental protection. Sheet metal bending can complete the processing of metal plates with less energy consumption, thereby reducing the waste of energy resources. At the same time, the optimized production process of sheet metal bending can help enterprises reduce production costs and improve efficiency, which is also a way to save energy and resources. Compared with traditional metal processing methods, sheet metal bending does not require the use of a large amount of liquid or gas, thereby reducing the emission of various chemicals during the processing process, effectively reducing environmental pollution and health hazards. The sheet metal bending process requires the use of digital equipment or computer control systems for programming and operation, which makes the production process more intelligent and efficient. The optimized production process of sheet metal bending can realize the automation, rapid transformation and employee operation comfort of the production line, thereby improving production efficiency and quality and reducing resource waste. The accuracy and consistency of the workpiece can be guaranteed during the sheet metal bending process, so that higher quality metal products can be produced. Compared with traditional metal processing methods, sheet metal bending can not only reduce machine friction, but also avoid some heating and stretching processes that may cause damage to the material.
