| Forging industry on the future development of domestic form 2008-02-14 16:37:13 (Has been accessed 16 times) Forging industry on the future development of domestic form I want to print my briefcase IE Favorites Add to Message Show Message In recent years, China's enormous production forging Tremendous progress has been made to achieve a certain scale and level of production, technology and equipment and management still can not meet the needs of the market, the Chinese forging industry is still forging hammer and Double-old friction for the press Lord, and the world still a large gap compared with developed countries, is far from satisfying the demand of the market at home and abroad forging urgent need to transform and upgrade. So far only about 150 built near the hot forging press production lines, and began developing precision forging hot, warm forging and cold forging process. 2002 output of the forgings nearly 400,000 tons, and production in the forging of about 2 million tons. Forging these fine (including cold, warm forgings) with nearly 100,000 tons. In Forging, cars forging nearly 300,000 tons. With the rapid development of China's auto industry, auto forgings in the future might reach 1.5 million tons, of which cars will account for 70 per cent of forgings. Forging owned by the domestic technology and production equipment is far from satisfying the needs of forgings, according to forecasts, China's future need for the forging technology are as follows: 1. Precision cold, a mild hot forming technology and non-ferrous metals forging technology. 2. Forging processing intelligent technology. 3. Composite forging technology. 4. Hydroforming technology and laser forming technology. 5. Other special forming technology. China's future need for the forging equipment as follows: 1. Alternative five tons of free high-speed hydraulic forging hammer machine, the forging of the existing hydraulic machine to transform or replaced. 2. Hot forging press line about 1600-6300 tons need 100 (2). 3.50-100KJ electro-hydraulic hammer about 50 (2). 4.1600-4000 tons screw press 30 (2). 5. Less than 1,600 tons of hot forging press some. 6.1200-1600 tons of the Multi-Position cold, warm forging for precision forging press about Taiwan 10-15. 7. Wedge mill, bar shear, the band sawing machine, the machine placed Zhan peace forging machine will be increased. 8. Heating equipment due to the increase in forging line will simultaneously increase. 9. Upsetting machine with high-speed machinery industry and the automobile industry's development will certainly be a big growth. 10. Forging auxiliary equipment, in particular the automation system will be increased. Since forging technological progress, mold manufacturing technology it will be a big development. To this end, China needs to mold the future equipment and technology are as follows: 1. High-speed machining center (vertical, horizontal, Gantry), in particular to more than 30,000 high-speed CNC milling machine. Foreign ordinary hot forging die processing, heat treatment has been introduced in the module 3-4 CNC machining center of Taiwan's high-speed production line from milling, EDM and grinding without amendment, dimensional accuracy and finish in full compliance with the technical requirements, good quality, high life expectancy, low cost. 2. Precision EDM machine. 3. Precision WEDM. |
