With the rapid development of electronic communications,
electrical appliances, automobiles and home appliances and other products, the growing
demand for precision stampings, technical requirements are also increasing, and
the application surface more and more widely, so a large number of ordinary
presses can not meet the production and super mass production, production and
technical requirements. High-speed precision press
high speed, automation and continuous punching is an effective way to improve
press productivity. Due to the number of times per
minute than the tonnage of high-speed precision presses slide stroke similar to
the ordinary presses more than five times higher, so high-speed precision presses not only high
precision stamping parts, surface quality, and long mold life.
In recent years, the stamping technology to keep the speed, precision and intelligent direction, the momentum of development of advanced high-speed presses, and therefore the emergence of a number of high-speed precision press and ultra-high-speed precision presses, such as Germany Las special company, Münster, Switzerland nbsp, Schuler, Germany, Japan, the rate of energy and electricity production companies, the development of small-tonnage high-speed precision presses, Number of strokes up to 2,000 times / minute, 3,000 beats / minute, 4,000 times / minute. In the load state, but also up to the standard super precision requirements. This indicates that high-speed precision press technology has developed to the ultra-high-speed ultra-precision stage.
Some foreign companies of small tonnage of high-speed precision presses Number of strokes divided into four speed grades: normal speed ≦ 250 beats / min, times high speed> 250 to 400 beats / min, high-speed> 400 to 1,000 times / min, super- speed ≧ 1,000 times / minute. Large tonnage of high-speed precision press slide the relatively low number of trips, such as 300 tons of large-scale high-speed precision presses, the number of slide stroke range is only about 160 to 400 beats / min, 100 tons of fin dedicated high-speed precision presses The slide stroke number range is generally about 150 to 250 beats / min.
Punching speed presses tonnage, slide stroke length and the number of products, process structure and materials process performance, automatic feeding speed and precision of many different elements, it is difficult to use simple numbers as the divided each grade boundaries, Therefore, the international high-speed precision presses range of rapid change is still yet to make a clear definition, usually the punching speed of 5 to 10 times higher than ordinary presses speed collectively referred to as high-speed precision stamping. From the situation of most enterprises in China's high-speed precision press, Chong times speed according to the the average slider minimum and maximum number of strokes or greater than the mean of 10 to 20% of the impulse rate is more reasonable and reference significance standards. Because the maximum number of strokes of the high-speed precision presses slider generally refers to the number of load-stroke. Imbalance presses running significantly increased when the number of trips up to a certain value, the dynamic changes of the dead under the slider, must be resolved so that the quality of the coil material feeding speed, mold performance and life equipment strength, stiffness and precision, the failure of automatic monitoring and stability, vibration and noise as well as lubrication and cooling system and a series of technical problems. Therefore, the application of high-speed precision presses the red times speed is critical.
