The introduction of this press process, WTB is called "by Dream Tour", from the selection argument to the procurement tenders, to the transportation and installation of production, 35,500 tons of high-energy screw press construction project lasted for nearly four years, which is fraught the hardships and challenges, but also carries the WTB's dream and hope. The company has organized a strategic development by the two power stations and aviation industry experts to participate in the selection of equipment and key expert consultation, we have conducted forging technology development and research activities, there are more than 30 units of more than 60 scholars, experts involved in helping WTB constantly optimize and improve the strategic development plan; WTB inspection team also repeatedly went to Germany, Austria and other places Investigagion equipment suppliers. The company ultimately chose SMSMeer SPK22400 new clutch screw press and the corresponding auxiliary equipment, and 20 008 in August officially signed import contracts.   35,500 tons of high-energy screw press includes a base including a total weight of 5800 tons, of which the largest single part of the weight of 340 tons, nearly 10 monomeric components weighing more than 100 tons. German SMSMEER company experts, WTB project team and related personnel, the machine five construction companies to install equipment nearly 100 people participated in the construction project.   From since October 8, 2010 the first batch of press parts approach, to May 31, 2011 trial forging products, which lasted 236 days. After the construction of large transport equipment presses, lifting 307 tons bench 345-ton beams and other large pieces of precision hoisting key nodes 590 tons heavy flywheel clutch assembly, electrical system, hydraulic system debugging; in solve special installation tool manufacturing 345 ton beam stand, the overall framework after installation and load prestressed laser measurement and other technical problems. From May 31 to formally put into trial wrought product in just 10 days, 10 days, WTB engineering and technical personnel and forging workers around the clock, hard work, overcoming difficulties, has completed more than one product of the process in the press development and trial production.   The world's most advanced forging equipment lead   commissioning ceremony June 11, and Professor Liu Dong from SMSMeer (China) Co., Ltd.韩剑锋manager and Northwestern Polytechnical University, introduced to the guests the 35,500 tons of high-energy screw press equipment features and technology advantages.   35,500 tons of high-energy screw press is by far the world's most advanced, one of the two largest screw press, can brief contact with the workpiece to force huge blow molding of metal products, the maximum impact force up to 35,500 tons. Its technology combines hammers and hydraulic advantages of both the electrical and aircraft owners blade, ideal for high-performance aircraft engines, special steels, titanium and nickel-based superalloy class structure of the product.   Compared with the traditional screw press, this new piece of equipment used in the clutch not only a significant increase in energy press forming, and can reduce about 87% of energy consumption, it is a veritable efficient "high-energy" equipment.   It is worth mentioning that the impact of this press speeds between 0.25 to 0.5 m / sec adjustable, controllable stroke forging, hammering energy variable; compared with conventional presses and hammers, to produce metallurgical quality more excellent organizational performance is more uniform, more precise size of a large overall forgings.
