数控转塔冲床的发展历史

Since the United States Wiedemann (WIEDEMANN) since the company invented the R2 manual punch press in 1932, CNC turret punch (foreign referred to as NCT) has been widely used in the field of sheet metal processing, continuous development in structure and performance.

1984 by technical experts Ji'nan Kaifeng CNC company developed the first mechanical CNC turret punch press. 1998 by the development of the first domestic hydraulic drive CNC turret punch. 2007 by technical experts Ji'nan Kaifeng CNC Machinery Co., FANUC company, Japan Federation of Estun company jointly developed CNC servo turret punch press, the first Taiwan has been used for 11 years, running well.

Early CNC turret punch automatic programming software in NC system, only manual programming, and now the CNC turret punch basically equipped with automatic programming software, the working efficiency and the complex parts processing capacity than before are leap improvement. On the sheet metal industry development situation, there should be a lot of room for development. But now engaged in sheet metal industry personnel, the performance of various types of CNC punch and the structure is sometimes not very well understood, the following is a brief introduction to all kinds of CNC turret punch.

According to the work principle of the driver striking head for CNC turret punch can be divided into three categories:

1 mechanical driven CNC turret punch press

This is one of the earliest development of machine tool CNC turret punch press, there are still some manufacturers in the production and use. Typical eshisamoto (MURATEC) C series, Amada (AMADA) ARIES series, PEGA series, COMA series, etc.. The numerical control turret punch press is driven by a main motor to drive the flywheel to rotate, and the inertia of the flywheel is used for stamping. This kind of machine tool has the advantages of simple structure, low price and stable performance. But the disadvantages of this type of machine tool is also obvious. First of all, the CNC turret punch press must wait for the flywheel to turn a circle, only to conduct a stamping, stamping stroke is fixed, so the stamping speed can not be improved, the current maximum of only 180 times / minute. This is now many manufacturers are no longer the main reason for the production of such a number of Chong (AMADA2013 ARIES production in Japan has long been discontinued). Secondly, because the stroke struck the head can not control the molding, stamping is not easy to control. Like this type of machine tools must be adjusted by the number of stamping die in order to achieve the ideal shape, adjustment is difficult. In addition, this type of machine tools and power consumption, large noise and other shortcomings.

2 hydraulic driven CNC turret punch press

With the development of technology, the hydraulic NC turret punch. This kind of machine tool has been widely used because of its many advantages. A typical representative of this kind of machine tool with Muratec (MURATEC) V series, Amada (AMADA) VIPROS series, TRUMPF (TRUMPF) TC series. This machine is driven by hydraulic cylinder controlled by stamping hammer head, electro-hydraulic servo valve. So in the stamping speed has a leap type of ascension. Up to 1000 times / min. Secondly, the hydraulic cylinder can be controlled, so it can control the striking head of the stroke adjusting mold, easy to use. Control of hammer head of the pressing mould at work, stamping noise can be reduced. In addition, through the communication with the manufacturer, you can carry out the rolling, rolling and other mold processing (mechanical type not). However, this type of machine tools are also a variety of shortcomings, first of all, this type of machine tool for the higher environmental requirements, the temperature is too high or too
