Axialization of printing machinery look forward to CNC system industry support

Under the premise of ensuring the safety and environmental protection of mechanical products, the equipment's ability to achieve high productivity, high quality, and reduced labor intensity has always been the three goals that people pursue. The continuous innovation, development, improvement, and replacement of any mechanical product always accompanied the development of printing machinery.

Shaft, shaftless, CNC

In order to maintain the synchronization and regular movement between the units, the basic features of the drive are: the power source drives the transmission components of each unit through a long axis, and then drives the device's actuator to complete the equipment's input through the transmission components. , Output tasks, which is the traditional "axis driven" printing machinery, is also the most basic transmission principles. With the development and application of contemporary digital control technology, the conditions for canceling this long axis have been fully matured. This means that each printing (or function) unit has one or more servo motor drives, which can also meet the printing requirements. Printing machinery This concept is often referred to in the industry as "shaftless technology," "shaftless drive," "electronic shaft drive," or "independent drive."

From the standpoint of standards and regulations, the reference to "shaftless" from the transmission of shafts is not scientific enough. People in the circle understand that while other industries may sound confused about Zhang Shi and the monk. Therefore, I suggest to call "CNC Technology" as well.

As we all know, China's largest machinery manufacturing industry is the automobile manufacturing industry, which reflects the comprehensive technological level of the machinery manufacturing industry, large-scale production programs and the pursuit of maximum profits, and the production process has been highly automated. At present, a large proportion of CNC machine tools, machining centers, and FMS (flexible processing systems) are geared to the automotive market. The state-supported machinery manufacturing industry also includes key equipment and machine tool industries. It reflects China’s ability and technical capacity to provide equipment for key industries such as defense, aviation, shipbuilding, automobiles, and power generation. These DC servo motors are the development process of an AC servo motor. The contemporary machine tool has already gone through the programming to realize the automatic processing of the three coordinate axes of the CNC machine tool. A machining center The automatic tool change machining A first-generation FMS (adopting the exchange workbench to realize the automatic flexible processing of multiple machines) A ​​second generation FMS (automated stereo library and multiple devices for automatic flexible processing) a third-generation FMS (elimination of the autostereoscopic library, the use of industrial robots to achieve the automation of the entire process), the common characteristics of these three generations of FMS flexible systems. The human ideal of an unmanned chemical plant has been realized. At the same time that CNC technology is widely used, another trend in the development of CNC machine tools is the emergence of compound machine tools. The machining scope of the machine tool has been further expanded, resulting in turning, milling, boring, and grinding. In the center, the process flow of parts processing is greatly shortened. Some entrepreneurs boldly proposed: a person, a composite machine tool, is a factory, a car engine box assembly, in a car, milling center can complete all milling, boring, drilling, expansion, tapping, Cars and other processes, a flame CNC cutting machine can create a small bridge.

The technological development of printing machinery and equipment will inevitably follow this path. From the earliest invented engravings of humans, to the invention of movable type printing, to Germany's Konebigbauer inventing the metal movable type letterpress printing presses, it has also undergone several hundred years of improvement to reach the advanced level of modern printing presses. Take the web press as an example to review the history of modern science and technology development. A similar conclusion can be drawn. At the beginning of the 30's, sheetfed letterpress printers have become the main force in the printing industry. Since the printing process is not continuous, the increase in printing speed is limited by the structure of the equipment, the speed is restricted, and a continuous printing press appears. , to greatly increase the speed of printing. The power source of the sheet-fed printing press is a mechanical inorganic speed-changing mechanism. Most of the devices use a slip motor. The power source of the power source of the web printing press is powerful, and the stepless speed regulation requires the use of a new power source. DC motor and SCR speed control. After the automation of the printing process, this equipment has solved the automation of paper control, folding, transfer, collection, registration, printing, and cleaning. However, web presses still rely on one or two parallel sources of power to drive the entire machine's various motions and functions through a long axis.
