Came 6 days on June 5, 2014, group of 2 machine tools assumes Jinan ” machine tool of high-grade numerical control and foundation make equipment ” national science and technology is great and special, ” large servo compressor ” the project is mixed through checking and accept at the same time in Dalian appraisal. This project relies on the home that provides for factory of Dalian of strange luck car compressor of first 25000KN large servo, achieved the new breakthrough of homebred punch technology, to breaking monopoly of market of foreign high end, drive indigenous auto industry to equip to be changed independently have important sense.
Punch is first technology that the car makes. Make rapid progress of the technology as contemporary car, new-style material, composite material is applied extensively, what equip to punch is flexible change and intelligence changes a requirement taller and taller. Technology of large servo punch broke through the concept of traditional and mechanical compressor completely, use technology of servo motor drive, cancelled flywheel, clutch, brake, provide punch energy directly by servo electric machinery, can ask according to different material, different technology in punch process, the stepless that achieves traversal speed and figuration power adjusts, can get used to thin plate to pull deep punch spare parts and high strenth armor plate, aluminium alloy board the form cutting that waits for new material, have the characteristic such as high quality, efficient, energy-saving environmental protection, it is the another innovation of punch technology and leap. Before, this one technology has the state such as day, heart only a few enterprise masters, the product line of large servo compressor that domestic car company uses also counts an import entirely.
Country of have the aid of urges action specially greatly again, the research that 2 machine tools took the lead in developing servo compressor technology in home mixes Jinan application. This acceptable compressor of 25000kN large servo, in advocate emulation imitate of curve of motion of drive of analyse of credit of transmission system motivation, servo and control system design, servo is optimized, mat of numerical control model develops malfunction of design, equipment to be diagnosed oneself reach the key such as long-range monitoring significant progress was obtained on the technology. Its development is successful, it is 2 machine tools are in Jinan to master and apply thin double arm to send makings punch technology, large multitask quickly on the foundation of compressor technology, in the another new breakthrough of punch technology domain, also indicate a technology of homebred car punch and international latest technology came true to conform to develop with synchronism in the round at the same time.
Check and accept meeting and appraisal to be able to believe ministry and organization of union of Chinese machinist trade to hold by labour respectively. Nearly 20 when come from labour to believe user of place of courtyard of ministry, mechanical federation, scientific research, car each expert attended the meeting. The member that the expert is comprised was listening to project finance affairs report of final accounting of revenue and expenditure and report of technical work summary, examined relevant check and accept a data, saw the moving case that the product is in factory of Dalian of strange luck car on the spot, after to the task medium concerned problem has inquiry, agree consistently to pass check and accept. Made following appraisal conclusion to the project at the same time: Main specifications index achieves this large servo compressor congener product international is advanced level. Project success development equips to improving our country the competitive actual strength of manufacturing industry, have important sense, have wide applied perspective.
