Precautions for purchasing CNC press brake bending machine and system development trend

Reading Time: 5 minutes

When choosing a CNC press brake bending machine, it is mainly to consider the length and thickness of the workpiece to be processed, which is relatively easy to understand. Of course, this refers to the situation of processing items by yourself. It is best to be able to make accurate choices. Only in this way can It can reduce the cost, and whether the selection of the bending machine is appropriate or not can be directly related to the cost.

Because the problem that everyone has to consider is the parts of the bending machine. If it is a small workpiece, the machine with a small tonnage is just right. If the processing of low carbon steel is engaged in a large range of concave models, it is appropriate to choose a machine tool with more than 100 tons in the purchase of CNC press brake bending machine. This can also greatly improve the efficiency of work and cut costs in half. Because the specific length of the workpiece is the most important reference standard for machine purchase.

Under different loads of the machine, the variation between the work surface and the slider of the CNC press brake bending machine may be four to five times that of the machine. Moreover, the adjustment parameters for various machines are also raised to the qualified parts coefficient. Because the short machine does not require many gaskets. It also makes it possible to shorten the overall time used in the production process. This also needs to be an important indicator of reference from the specific aspects of stainless steel.

Of course, the choice of CNC press brake bending machine is mainly based on its own situation, which is certain and the biggest direct factor in reducing production costs. NANJING PRIMA CNC MACHINERY co., LTD. formulates the best solution according to the needs of customers, so as to maximize the interests of customers.

Analysis of the three major development trends of CNC press brake bending machine system

The CNC press brake bending machine is a machine that can bend thin plates. Its structure mainly 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 plates are connected, the base is composed of a seat shell, a coil and a cover plate, the coil is placed in a 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, and the operation is also very simple. From the current point of view, the development trend of CNC press brake bending machine system is mainly reflected in three aspects: performance, function and architecture, which are specifically expressed as:

Performance

1. High precision, high speed and high efficiency

Efficiency and quality are the key performance indicators of advanced manufacturing technology and the main body of advanced manufacturing technology. If high-speed CPU chips, RISC chips, multi-CPU control systems, high-resolution detection components, AC digital servo systems, supporting electric spindles, linear motors and other technologies are used, the efficiency can be greatly improved, the quality and grade of products can be improved, and the production cycle can be shortened. Improve market competitiveness. In the next few years, the ultra-precision CNC press brake bending machine punching machine is developing towards precision, high speed, intelligence and nanotechnology, and it is a new generation of CNC press brake bending machine tool that converges.

2. Flexibility

The CNC press brake bending machine system adopts a new generation of modular design, with wider functional coverage and stronger reliability, which can meet the needs of different users. The same group control system can automatically adjust the information flow dynamically according to different production processes, and play the function of the group control system.

3. Multi-axis

Multi-axis linkage processing, after the parts are clamped on a CNC press brake bending machine machine tool, automatic tool change, rotating spindle head, rotating table and other operations can be performed to complete multi-process and multi-surface composite processing, not only high finish, And the efficiency is also greatly improved.

4. Open software and hardware

The user can carry out the secondary development of the CNC press brake bending machine system software according to their own needs, and the user’s scope of use is no longer restricted by the manufacturer.

5. Intelligent

In the field of CNC press brake bending machine technology, the research and application of real-time intelligent control are developing along: adaptive control, fuzzy control, neural network control, expert control, learning control, feedforward control, etc. Such as programming expert system fault diagnosis expert system, when the system fails, the diagnosis and maintenance are realized intelligently.

Function

1. Graphical user interface

The user interface is the dialogue interface between the CNC press brake bending machine system and the user. The graphical user interface should be suitable for all kinds of users including non-professional users. It can be operated through the window and the sheet, which can realize graphic simulation, graphic dynamic tracking and simulation. and fast programming.

2. Visualization of scientific computing

Information exchange is no longer limited to expressing in words and language, and can directly use visual information such as graphics, images, and animations. Visualization technology can be used for CAD/CAM, automatic parameter setting, tool compensation, display and visual simulation of machining process.

3. Diversification of interpolation and compensation

The interpolation methods include linear interpolation, circular interpolation, cylindrical interpolation, spatial elliptic surface interpolation, thread interpolation, polar coordinate interpolation, polynomial interpolation, etc. Compensation functions include verticality compensation, clearance compensation, error compensation of quadrant crossing during circular interpolation, error compensation of pitch and measurement system, tool radius compensation, temperature compensation, etc.

4. High-performance built-in

The CNC press brake bending machine system is equipped with a high-performance PLC, which can be programmed directly with ladder diagrams or high-level languages, and can be debugged and edited online to establish its own application program.

Architecture

1. Integration

Adopt highly integrated CPU, RISC chips, large-scale programmable integrated circuits, and special-purpose integrated circuit chips to improve the integrated circuit density, software and hardware running speed and system reliability of the CNC press brake bending machine system.

2. Modular

Realize the integration and standardization of CNC press brake bending machine system, and make CPU, memory, position servo, PLC, input and output interface, communication and other modules into standard serial products to form different grades of CNC press brake bending machine systems.
