Team card
China Aerospace Science and Technology Corporation six homes in 7103 Factory 34 workshop process group is mainly responsible for the routine carrying liquid coal, model castings delivery task team total crew of 11, has been advanced team of six good team of China Aerospace Science and Technology Corporation, the plant level, as well as hospital level the honorary title of an exemplary team.
11 members of this team, in addition to the three 60, all 80, is one such team to the "high-quality, low cost, high yield and efficient" production goal to promote the aerospace fluid power industry casting process and technology are rapidly developments. The unique spirit of this team are concise, as they personally designed the production of engine castings, stand firm and trustworthy.
Playing time: to challenge the fundamental strength
June 20, 2011, 7103 Factory 34 workshop for the technology group, is a memorable day.
That day, the exciting news came from the courtyard: six homes passed Group Company, a heavy launch vehicle engine program review. At the moment, the casting process members of the group as a whole have a long sigh of relief, successful project which is also full of a pay and sweat a day in December 2010, the head of the high-Huai Sheng received a UG model diagram from the courtyard the hope that he and his team can not affect the existing work under the premise, drawing on the engine manufacturing into the wood look like machines, to make early preparations for the follow-up to carry engine development work.
Expand a look, I suddenly was scary monster of several meters high, it can be said to build factories so far, we have not done such a great project to have to make two complex we are not afraid of the most important is that it is beyond the our processing capacity, which was a huge challenge. "
The brain is rapid rotation, apart from emergency to a group of technology "big get" - call Wang Hai, the national super technician. Frantically rushed to Hai facing the drawings was silent for a moment, and two in the front line has 20 years of work experience, veteran, well aware of the exploration to undertake this work is to cross the river by feeling the stones, the process is inevitably difficult and tortuous. The results also full of uncertainty. Hai payable to the statement: "As long as the courtyard there is a need, factory support, technical details to do the overall coordination to run, hard to have to do!" Sure enough, his thoughts and Huai Sheng own thinking. They so no idea the problem back to a process group.
34 workshop as 7103 plants the only foundry in recent years to produce rapid rise in assignments, and then free up the manpower to do such a huge project, so this workshop have been restricting production capacity due to lack of staff even more stretched. " .
When they took the drawings, his face filled with private access "military order" will give a workshop to bring more heavy tasks whereabouts of apology expressions Workshop Director Yang Huanqing report, Yang Huanqing immediate support: "Our shop people, is the need for such good challenge, and the courage to bear the self-confidence and boldness - "He changed the subject, enthusiasm alone is not enough, we want to test it as a test of our basic work to do done pretty!"
Yang Huanqing of fear is not without reason, in addition to this UG diagram, they even a drawing, there is no similar experience in the past, technical reserves are very limited. This enormous project, we must first split the "anatomical" drawings of the parts, engines of various types of pipe are angled, not enough raw materials, design drawings can not be converted to production, then, do not have the wood material the strength of the metal material, to ensure the safe use of the connection is difficult to solve using ordinary adhesive. The spate of problems so that early deadlock.
Hai, with rich wood mold development experts with experience as a prototype developed by the project technical director, to lead this 80 young technology research team. Initiated by the impact.
Tao go Yunfei, winter to spring, time flies. Problems on the production capacity of the technical difficulties we are not afraid, really a headache, in March 2011 during the days of the processing engine nozzle, seeing the delivery date approaching day by day, we all ready, but the processing of parking spaces Teng out kept coordinate kept waiting, and even torture I kind of regret taking the task. "recall the original, high Wye wins still deep emotion.
Throughout the prototype development process, in addition to the nozzle, all other parts are casting workshop to design, manufacture, assembly, because the nozzle is too great, the overall curvature of manual operation is simply no way to control, you must first machine lathe on the first grinding out polished by hand in order to continue.
But they encountered a small part of the many problems later to rough statistics, throughout the prototype development process, design decomposition of 58 bends, the use of 20 cubic meters of wood, design and manufacture of various parts one thousand, the day officially assembled prototype, these parts are covered with a full three large trucks.
During the president Tan Yonghua came to the assembly site, our work is certainly the next day, many experts its Kuiran great momentum shocked, were full of praise. "GAO Huai Sheng smiled," in 2012 the focus of our work or return to nature, back to the basics, but this time from the process point of view of the task is completed, we have a clear conscience, even if the role played by only a little, Zaikuzailei value! "
Playing information: based on technology Heights
Not for the constraints of the traditional model, not for the limitations of conventional vision, not the fetters of existing experience, this is the best platform for innovation in the technology group for every member. New group of young people, our ideas are not hard-irrigation technology, allow them to work immediately, but to encourage breakthrough thinking caps, concerned about the cutting-edge theory and the experience gained from practice, to seek consensus from the exchange and to foster a new, forward-looking way of thinking, so as to achieve inner mutual recognition, and behavior influence each other a good atmosphere. "high Huai Sheng confident that the workshop this new way of management education.
In addition to the conventional carriage, liquid coal, models casting delivery task 34 workshop also bears the load characteristics of the engine simulation of the production tasks. The general requirements in accordance with a particular model of carrier rockets, the old product engine load characteristics of the test and control loop simulation. Components of the small number of old products, unable to meet the delivery task group from the process to achieve the degree of difficulty, the processing cost point of view considered to determine the main casting process, manufacturing load characteristics of the engine simulation program.
After repeated communication workshop leadership and technology group, the final decision to take a leading role by just attended one year of the young man Ji Yanqing, composed of a casting technology backbone constituted entirely by the 80 after tackling team. "We did not worry about whether to complete the task, backward technology and equipment, scarcity of resources is not hindered, because the critical moment, there is always help and support of leading chefs, we are steadfast in our work, all difficulties will be solved." This is the Ji Yanqing this emerging technology backbone on behalf of process group points to the aspirations of young people. This to be delivered 80% of the total task of casting the load characteristics of the engine simulation, casting it is necessary to guarantee the appearance but also to ensure the center of mass unchanged, on the basis of ensuring the existing workload, but also reduce costs and improve efficiency, work One can imagine the great difficulty. Solid technical foundation for the rich discipline theory of practical experience coupled with continuous temper, this youthful team gradually emit bright light: the successful completion of the delivery of eight sets of engine goals.
