Qin Maohua, a senior technician of Guangxi Yuchai Machinery Co., Ltd. He studied the 3D printing technology, formed a unique rapid manufacturing of new technologies, the use of 3D printing technology in a relatively short period of time to create a large complex diesel engine cylinder blocks and other key parts in the country Is a leading position, the company for each year to save the cost of more than 600 million.He launched the innovative project "new heavy machine body advanced rapid manufacturing technology" won the Guangxi advanced tooling technology achievement award, "large-scale engine key parts rapid manufacturing process "He won the China Machinery Manufacturing Technology Award for scientific and technological achievements. He has won the 'Guangxi labor model' 'Guangxi May 1 Labor Medal' 'Guangxi technical experts' 'Guangxi outstanding high-skilled talent'.
An ordinary job, the first step of precision, he will file cutting, shoveling, grinding out the accuracy, into their own life scale.When the diesel engine and his team innovation technology to shorten the production cycle at the same time, a superb technology To create a new industry history of the craftsmen, life is more thickness.He is Guangxi Yuchai Machinery Co., Ltd. mold industry skills master, senior technician - Qin Maohua.
Hard training into 3D rapid manufacturing production experts
In 1999, from the Liuzhou senior technical school mold fitter professional Qin Maohua, became a worker of Yuchai.Then assigned to the post of Qin Maohua, see the mold drawings are very difficult, but fortunately he met 'Bole' master Chen Jinyuan.
'Small Tan do not be afraid, you are much stronger than me, I only read junior high school graduation, and now do not do well?' Master's words to Qin Maohua great confidence in order to break the drawings off, Qin Maohua became master and Workshop technician 'sturgeon.' In the master and technical staff when drawing, Qin Maohua looked at the side, do not know, slowly, he not only learn to see the map, but also learned the mapping.
In order to grasp the skills of the fitter, Qin Maohua will be in the master of the time to concentrate on every step of the observation of the steps, in order to grasp the skills of the fitter, Qin Maohua hand will be scratched by the file, so far his hands still have a lot of old scars. Every detail, and then recorded in the notebook, go back and then slowly pondering their own. Soon, Qin Maohua learned the master Chen Jinyuan 'three law a fine' unique skills.
In 2008 to 2012 just a few years, Qin Maohua with the kind of hard study of the tenacity, from a young juvenile, rapid growth for the company's technical backbone.
In recent years, due to the development needs of the company, Qin Maohua into the field of 3D printing work, responsible for the company's rapid manufacturing of new products. 'Equipment feeding is not normal, easy to offset laser beam, parts size accuracy is not compliance, easy to deformation parts ...' 3D Printing in the new materials, new technology, new technology applications can no reference can be learned.However, the beginning of the technical research from the beginning, Qin Maohua from the beginning did not fear.
Qin Maohua led his team staff day and night to amend the various parameters set, adjust the material process, and constantly sum up and improve the processing of 3D printing technology processing methods.After several years of technology accumulation, 3D printing technology in the production of efficient use, and ultimately formed The industry's unique rapid manufacturing of new technology to produce a 6-cylinder diesel engine body blank, for example, the use of rapid prototyping technology only 20 days, and the traditional way to produce molds need 3 months, time speed 3 times, not only for the enterprise Saving costs, but also for new products to quickly enter the market to save time.
From solo to collective innovation
After 10 years of 'fought,' Qin Maohua not only the type of file cutting, scraping scraping, grinding and other fitter technology using skilled, but also master a variety of operating equipment, such as 3D printing, digital moldless precision molding machine, welder , Liquid sandblasting machine, airway test bed, forklift, ground control crane, etc. So far, Yuchai application of 3D technology produced by the diesel engine body weight of 4 tons.Using 3D printing fast manufacturing, you can develop for the company's mold And manufacturing savings of more than 600 million cost.
2012 to 2015, Qin Maohua led the team to use 'moldless casting precision forming technology' has developed the engine block, cylinder head, tube, shell and other types of different types and types of castings more than 300 pieces, the application of the technology for the enterprise Saving mold development costs about 40 million yuan, bringing about 20 million yuan of new profits, enterprises to obtain indirect economic benefits of about 200 million yuan.
Qin Maohua is the eyes of the invention of the 'invented king', he not only has a wealth of work experience and superb technology, can independently solve the mold manufacturing debugging process of various technical problems, but also the use of years of accumulated experience to participate in the innovation of many advanced Such as 'precision mold assembly precision positioning technology' 'mold narrow slot processing technology' 'a special chisel blade grinding used in the angle of technology' and other advanced technology operation method of promotion and application, greatly reduced The labor intensity of workers, a substantial increase in work efficiency and product quality.
'A person's strength is weak after all, only to everyone's wisdom together in order to more effectively solve a variety of technical problems, to achieve technological innovation.' Everyone pick firewood high 'Well, this reason we all understand!' Tan Maohua No longer confined to their own in the process of technological innovation 'alone', but led the team for collective innovation.
In 2013, the "Qin Maohua Laomao Innovation Studio", which was named after Tan Maohua, was promoted to the autonomous region-level labor innovation studio in 2014. Since 2013, the studio has carried out more than 100 technical quality problems, such as "diesel engine complex Body automation casting method "by the 2013 China Machinery Manufacturing Technology Science and Technology Achievement Award;" large-scale diesel engine wood-plastic composite mold technology innovation and industrialization "by the China Machinery Industry Science and Technology Award for technical innovation achievements second prize.
Is willing to do the inheritance of the 'lead the way'
Today, Qin Maohua's apprentice has more than 10, often receive an apprentice, he will encourage the apprentice said: 'Everything should be like a craftsman, like to live fine, but also to do the same thing, Doing so hard, you can live a wonderful life.
Whether it is in the work or usually, once in the technological innovation with a 'whimsy', Qin Maohua always in time with colleagues to share the exchange, or to some technical backbone humbly ask for advice.
27 years old He Shengwei is Tan Maohua apprentice, 'master is a zealous! I was still fitter, several times encountered problems can not be resolved, all to his help. Master every time will be very patient, very detailed to explain to me, If the teacher has been able to follow the master to learn that the good ah! At that time He Shengwei extremely eager to work with Qin Maohua.One day, He Shengwei chance finally come. Technology Department of the news of a release, He Shengwei Immediately reported on the name, but also successfully passed the assessment, since he and Qin Maohua also became a teacher and friends of the mentoring relationship.
There are 8 members, including 50% of the members in Yuchai won the master and above the technical positions of the appointment.Qin Maohua has also been committed to the studio to build a platform for the training of skilled personnel, through the development of fitter Skills level training, division with only training, technical exchange research, skills contest and other forms of skills to 'pass with the band' in the form of better pass down.
From the eternal to the teacher, Qin Maohua with the accuracy of each part, inscribed an ordinary post on the era of craftsmen scale.Perhaps he is only a small screw in the engine, but it has the responsibility of Taishan and the insistence of the owner.
