Distinguish and analyze the difference between CNC bending machine and sheet metal bending machine

by:WORLD     2022-08-05

There are still many types of products on the market, and at the same time, the replacement of products is relatively fast. Therefore, many people will be dazzled by these products that look very similar, and do not know how to choose. Today, we will tell you the difference between CNC bending machine and sheet metal bending machine!

a Features of CNC bending machine:


1. Direct angle programming, with angle compensation function.


2. The real-time detection and feedback correction of the grating ruler, the full closed-loop control, the positioning accuracy of the back gauge and the dead gauge of the slider are:±0.02mm.


3. The upper die adopts a quick clamping device, and the lower die adopts a wedge deformation compensation mechanism.


4. With multi-step programming function, it can realize multi-automatic operation, complete one-time processing of multi-step parts, and improve production efficiency.


5. According to user needs, the imported hydraulic system with stable performance and compact structure can be selected, and the back gauge can be driven by ball screw and synchronous belt.


b The full name of the sheet metal bending machine is the hydraulic sheet metal bending machine, and its characteristics are:


1. It adopts all-steel welded structure with sufficient strength and rigidity.


2. Hydraulic upper transmission, the oil cylinders at both ends of the machine tool are placed on the slider to directly drive the sliding work.


3. The slider synchronization mechanism adopts torsion shaft forced synchronization.


4. The mechanical stopper structure is adopted, which is stable and reliable.


5. The slider stroke is motorized and quickly adjusted, manually fine-tuned, and the counter is displayed.


6. Wedge-type deflection compensation mechanism to ensure high bending accuracy.

The difference between hydraulic press brake and CNC press brake


The CNC bending machine is a CNC operating system added to the ordinary hydraulic bending machine. It is an upgraded product of the ordinary bending machine. Frequent process changes can reduce the labor intensity of the operator. However, the operating skills of the operators are higher than those of ordinary hydraulic press brakes.


Compared with the hydraulic bending machine, the most characteristic feature of the CNC bending machine is its CNC operating system, which is an upgrade of the ordinary bending machine, which reduces the labor force of the operator and enhances the processing efficiency. But at the same time, the operation requirements and skills of CNC bending machine are much higher than that of hydraulic bending machine, and it is relatively complicated.


The CNC bending machine has the function of multi-step programming, which can realize multi-automatic operation and complete one-time processing of multi-step parts. The hydraulic bending machine is energized by the wire to the coil, and after the electricity is energized, the pressure plate is gravitational, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into various workpiece requirements, and the workpiece with side walls can be processed.


The hydraulic bending machine includes a bracket, a worktable and a clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil It is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by the wire, and after the electricity is energized, the pressure plate is gravitationalized, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into various workpiece requirements, and the workpiece with side walls can be processed.
