The down-moving bending machine is a common sheet metal processing equipment, also known as the down-stroke bending machine or the pendulum bending machine. It is mainly composed of fuselage, workbench, upper mold, lower mold, control system and so on.
The working principle of the down-moving bending machine is: put the metal sheet on the workbench, the upper mold presses the metal sheet, and the lower mold moves downward, so that the metal sheet is bent between the upper mold and the lower mold, and finally forms the desired shape. desired shape. The advantages of the down-moving bending machine are simple operation, high bending precision, wide application range and high production efficiency.
Down-moving bending machines are widely used in various sheet metal processing industries, such as machinery manufacturing, aerospace, automobile manufacturing, electronic communications, etc. It can be used to produce various parts, such as chassis, racks, frames, brackets, etc.
The down-moving bending machine has the following advantages and characteristics:
1. Simple operation: The operation of the down-moving bending machine is relatively simple, and does not require too much technical experience and professional knowledge. Operators only need simple training to start operation.
2. High bending precision: The bottom-moving bending machine uses the pressure of the upper and lower molds to complete the bending, which can ensure the accuracy of the bending angle and bending lines, thereby ensuring the quality of the processed parts.
Wide range of application: The down-moving bending machine can process various metal plates, such as steel plates, stainless steel plates, aluminum plates, etc., and has a wide range of applications.
3. High production efficiency: The down-moving bending machine adopts electro-hydraulic servo system, which can realize high-speed and high-precision bending processing and improve production efficiency.
