What is the trend of the application domain of bending machine? The following is a brief introduction to the trend of mould application in bending machine, many users now tend to use CNC bending machines, however, the market of ordinary bending machine tool is still very large, which is mainly used for the processing of sheet metal bending with various sizes. There is a wide market in the processing industry of large electrical control cabinet, which can also be used in other high-volume sheet metal stainless steel processing.
CNC sheet metal bending machine system presents three aspects of development trend.
Hydraulic sheet metal bending machine is a machine that can bend the thin plate, its structure mainly includes the bracket, table and clamping plate, the table is placed on a bracket and the workbench is made of base and press plate. The base is connected to the clamping plate by hinges, the base is made up of the shell, coil and cover, the coil is placed in the hollow of the shell, and the top of the depression is covered with a cover. When used, the wire is electrically charged to the coil, and the power is generated to generate gravity to the pressure plate, so as to realize the clamping between the laminated plate and the base. Because of the electric magnetic clamping, it can be used to make a variety of workpiece requirements, and it can be processed to the workpiece of the side wall, and it is very simple to operate. At present, the development trend of CNC bending machine system is mainly reflected in the three aspects: performance, function and architecture. The specific expression is:
1. The performance
1). High speed and efficiency
Efficiency and quality are the key performance indicators of advanced manufacturing technology and the main body of advanced manufacturing technology. If adopting high speed CPU chip, RISC chip, CPU control system, high resolution detecting element, ac digital servo system, form a complete set of motorized spindle, linear motor technology, it can greatly increase efficiency, and improve the quality and grade of products, shorten production cycle and improve the market competition ability. In the next few years, the ultra-precision CNC bending machine presses the new generation of CNC bending machine machine with the development of precision, high speed, intelligentization and nanometer development.
2). Flexibility
The CNC bending machine system adopts a new generation of modular design, with wider function coverage and stronger reliability, which can meet the needs of different users. The same group control system can dynamically adjust the information flow according to different production processes, and play the function of group control system.
3). Multi-axis
The multi-axis linkage machining, after the last loading of a CNC bending machine, the machine can be used for automatic knife changing, rotating spindle head, rotating table, etc. This can complete the multi-process, multi-surface compound processing, not only the finish is high, and the efficiency also greatly increases.
4). The opening of hardware and software
Users can make the second development of CNC bending machine system software according to their own needs, and the user's use scope is no longer restricted by the manufacturer.
5). Intelligence
In the field of CNC sheet bending machine technology, research and application of real-time intelligent control is developed along the adaptive control, fuzzy control, neural network control, expert control, learning control, feedforward control, etc. Such as programming expert system and troubleshooting expert system, when the system fails, the diagnosis, maintenance and other realization become intelligent.
2. The function
1). Graphical user interface
User interface is the interface between the CNC metal bending machine system and the user. The graphical user interface should be suitable for the use of a variety of users including non-professional, through the window and the single operation, dynamic tracking, which can realize graphic simulation and rapid programming, and other functions.
2). Visualization of scientific calculation
Information communication is no longer limited to words, but can be used directly in visual information such as graphics, images and animation. Visualization techniques can be used for CAD/CAM, parameter automatic setting, tool compensation, display and visual simulation of machining process.
3). Diversification of interpolation and compensation
The interpolation method has linear interpolation, circular interpolation, cylindrical interpolation, space elliptical surface interpolation, thread interpolation, polar coordinate interpolation, polynomial interpolation, etc. The compensation function has vertical compensation, gap compensation, arc interpolation error compensation, pitch and measurement system error compensation, tool radius compensation, temperature compensation, etc.
4). High performance built-in
High performance PLC in the bending system can be programmed directly with ladder or advanced language, and can be adjusted online and edited online to build up its own application.
3. The system structure
1). Integration
It can use highly integrated CPU, RISC chip and large scale programmable integrated circuit, and application-specific integrated circuit chips to improve the integrated circuit density of CNC plate bending machine system and the running speed and the reliability of the system hardware and software.
2). Modularity
To realize the integration and standardization of CNC bending machine system, the CPU, memory, position servo, PLC, input and output interface, communication module, etc. are used as standard series products to form the numerical control bending machine system of different grades.
