CNC Press Brake is an automated equipment used for bending metal sheets. It uses CNC technology to accurately control the bending angle, length, speed and other parameters. The following is a detailed introduction
Working principle: CNC Press Brake use computer control systems (CNC) to control servo motors or hydraulic systems, which in turn drive the workbench and bending molds to move. The metal sheet to be processed is placed on the workbench, and its position is determined by the positioning device. Then the upper die descends and cooperates with the lower die to apply pressure to the sheet, causing it to bend and deform according to the preset program, thereby obtaining the required bending shape and size.
Structural composition:
Body: usually adopts high-strength cast iron or steel plate welding structure, with good rigidity and stability, and can withstand the huge pressure during the bending process.
Workbench: used to place the metal sheet to be bent, with positioning devices and clamping devices on the table to ensure that the sheet is accurately positioned and will not move during the bending process.
Bending mold: including upper mold and lower mold, molds of different shapes and sizes can be replaced according to different bending requirements. The material of the mold is usually high-hardness, high-strength alloy steel to ensure its wear resistance and service life.
CNC system: It is the core control part of the bending machine. The operator inputs the bending parameters such as bending angle, length, speed, etc. through programming or using the human-machine interface. The CNC system controls the movement of the motor or hydraulic system according to these parameters to achieve precise bending operations.
Drive system: It is divided into two types: hydraulic drive and electric drive. The hydraulic drive system has the advantages of large output force and smooth operation; the electric drive system has the characteristics of high precision, fast response speed, energy saving and environmental protection.
advantage:
High precision: It can achieve very high bending accuracy. The general angle error can be controlled within ±0.1°, and the length error can be controlled within ±0.1mm, meeting the needs of various high-precision sheet metal processing.
High efficiency: The CNC system can quickly and accurately execute the preset program, automatically complete multiple bending steps, and greatly improve the processing efficiency. Compared with traditional manual bending machines, the production efficiency of CNC bending machines can be increased several times or even dozens of times.
High flexibility: Just change the program in the CNC system, you can easily achieve bending processing of different shapes and sizes. There is no need to frequently change molds and adjust equipment like traditional bending machines, and it can quickly adapt to small batches and multi-variety production needs.
Easy operation: The operating interface of the CNC Press Brake usually adopts a graphical programming method. The operator only needs to enter the relevant parameters according to the prompts on the screen to complete programming and operation, without the need for complex professional knowledge and rich experience.
Application Areas:
Sheet metal processing: In the production of various metal products, such as chassis cabinets, power distribution cabinets, elevator cars, air conditioning shells, etc., CNC Press Brake are widely used to bend sheet metal into various shapes, and are indispensable key equipment in sheet metal processing.
Automobile manufacturing: Many parts of automobile bodies, such as doors, engine hoods, trunk lids, etc., require CNC Press Brake to bend metal sheets to achieve complex body shapes and high-precision assembly requirements.
Aerospace: In the field of aerospace, the precision and quality requirements for parts are extremely high. CNC bending machines can meet the needs of high-precision bending of metal sheets in the manufacturing of aerospace parts, such as aircraft wings and fuselage structural parts.
Electronic equipment: The shells, radiators and other parts of electronic equipment usually also need to be processed by CNC bending machines to ensure their dimensional accuracy and appearance quality, and meet the development trend of miniaturization and high precision of electronic equipment.
