Twist-axis synchronous CNC press brake and electro-hydraulic synchronous CNC press brake are semi-automatic synchronizations that have evolved from pure mechanical synchronization to mechanical-hydraulic synchronization. Twist-axis synchronization can be divided into two forms: digital display and numerical control .
Digital display refers to the addition of a grating ruler to a conventional machine tool, which can digitally display the current position and displacement but cannot be programmed.
Numerical control refers to the ability to program on a computer and then control the machine through the program on the computer. In other words, it involves digitally controlling the machining process.
The difference between twist-axis synchronous digital display press brake and twist-axis synchronous numerical control press brake is evident. Digital display still requires manual operation and cannot achieve automatic control. On the other hand, numerical control uses computer programs to control the operation of electric motors, enabling program linkage control and rotational speed of multiple motors. It can also process complex curved trajectories, achieving automation and unmanned operation.
The main difference between electro-hydraulic servo CNC press brake and ordinary CNC press brake lies in whether they have feedback loops and whether they have electro-hydraulic bending machine compensation. It is important to differentiate between the two. Electro-hydraulic synchronous servo press brake combines the advantages of electrical and hydraulic aspects, offering high control precision, fast response speed, high output power, flexible signal processing, and the ability to implement feedback of various parameters.
In summary, Wuxi Shenchong selects press brakes based on actual processing needs. Electro-hydraulic servo synchronous press brakes offer high precision, real-time error feedback, and strong resistance to off-center loads. Twist-axis synchronous press brakes have lower precision, no error feedback, and poor resistance to off-center loads. Electro-hydraulic servo press brakes are more complex and have higher prices than twist-axis synchronous press brakes.
There are many types of CNC press brakes, and some content is applicable to various types of press brakes, meaning it is not specific. Now let's discuss the aspects to consider when using CNC press brakes:
1. Bending precision of the press brake
Bending precision is a parameter that needs careful consideration as it determines which type of press brake to use. Generally, if the bending precision requirement is within ±1°, it is best to choose a CNC press brake because its slide repeatability is around ±0.0004mm, which is quite accurate.
2. Lifting and installation of hydraulic press brake
(1) When lifting and moving the hydraulic press brake, attention should be paid to the center of gravity to avoid accidents such as the machine flipping over.
(2) It should be installed on a foundation and securely fastened with anchor bolts before performing alignment.
3. Hydraulic control system of the hydraulic press brake
The hydraulic control system is a crucial and important part of the hydraulic press brake, requiring standardization and automation. The control methods generally include:
Central control block: Combining three control blocks into one, usually located in the center of the machine.
Three-block control: Consisting of three control blocks, mainly proportional directional valves, position monitoring directional valves, and backpressure components.
