Using large hydraulic machine Germany and Improvement Published: 2012.08.11 News Sources: Hebei Horse Hydraulic Co. FAW Qingdao Automobile Factory, China FAW Group Corporation, a wholly owned subsidiary of large state enterprises. 1995 began mass production of diesel flathead Jiefang truck and its products, and has developed into a flat truck and most all varieties, the widest range of the manufacturer, the product has entered the international market. In the card by the National Quality Inspection Bureau of Technical Supervision in 1997 conducted the second, the same year passed the ISO9001 international quality system certification. Usage: 5100T press is my factory introduction of Germany's SMS-HASENCLEVER a fully automatic control of large hydraulic machine, the host and the upper and lower mold used in all SIEMENS-SIMATIC-S7 automatic control system, hydraulic control system which is accurate and reliable, balanced section mechanical hydraulic double protection, high precision parts, simple operation control, high security and stability, and its span is the most similar equipment, this is still a world-class production of automotive equipment stringer. Mold using modular assembly structure, thickness of the red drop 10mm, length of 12m steel material, the use of advanced quick-change punch, stable pressure-type quality, and I only domestic plant pioneered the joint pressure type (stringers, lined plate forming a thickness of up to 14mm). But beginning use, 5000T press due to the strong pressure, span, often resulting in some minor quality issues, such as the partial pressure of the hole dislocation, scratches, burrs, etc. And some time ago, 5100T press blanking when the stringer plate punching unstable operating conditions, often greater shock and vibration, seriously affecting their life. With the continuous development of new products, stringer board length models more than 11m, stringer plate material also gradually develop high strength, super-stringers for these long, even by their punching power optimization full travel distribution, equipment already close to the rated load state, so the impact of any link punching power will inevitably lead to the deviation of the instantaneous overload devices, causing vibration. I plant the existing structure and main stringers blanking standard punching die basically retains the original mold of the German model, to adapt to the new products have done some improvements, the main structure and equipment, large-mold package. But blanking force likely to cause uneven edge blanking dies in cut pile lows around punching force feeding, in fact, the scene observed severe vibration of the mold is also present in this region. In view of this, our factory technicians to modify some of the standard improved punching force distribution. The main idea is to improve and strive to make stringer plate blanking punching force evenly distributed in all the work trip, but there are special circumstances are easy to adjust.
