Construction began in 1958 and was completed and put into production in 1960. In the past 60 years, the Baoding Transformer Factory of the year has been transformed into Baoding Tianwei Baobian Electric Co., Ltd. In the tide of reform and opening up, the company actively responded to the national call and insisted on innovation. Nowadays, it has not only realized a huge leap from the initial production capacity of 10 kV to a maximum of 1000 kV transformers, but also independently researched and developed more than 30 'China's first set' technological innovations, becoming the only one in China that can develop large-scale shifts. Phase transformer manufacturer.
The development and growth of the enterprise is inseparable from people. In Baoding Tianwei Baobian Electric Co., Ltd., there is a team called the cut iron group. Their job is to process the core pieces for the core components of the transformer. They call them 'steel tailors'.
Crimson is one of them. In 29 years, more than 500 million pieces of iron core pieces, zero accidents, and continuous technological innovation, she has accumulated more than 10 million yuan for the company's cost reduction.
In September 1989, Yan Hong was assigned to the work of the cut iron group from the technical school of Baoding Transformer Factory. In the men's group, she worked for many years.
The work of cutting iron is very common, and it does not require special advanced techniques. But cutting iron is a fine work. It is simple to say. It is not easy to do well. The requirements for size and burrs are almost harsh. The raw material of iron core is Silicon steel sheet, hard and brittle, very difficult to handle. 0.5 mm is the maximum tolerance that can be tolerated by the core piece, and 0.02 mm is the maximum limit of the knife edge burr. 'Even if the maximum error that can be tolerated is only 0.1 mm, it cannot be placed. If you put the unqualified product on the transformer, it will have disastrous consequences. ' 戚红 said.
In the workshop, how does the master teach, how the apprentice does it, this is the habit. At the beginning, the blush also cut the iron for 10 years in a step-by-step manner. Until 2000, the cut iron group ushered in the first automation equipment. The blush that had never touched the automatic production line was so excited. However, after a short time, she would not be happy.
Due to the structure of the equipment, the production line can't cut all the rolls at once, and each piece of material will produce a tail of more than ten meters. If the finished product is not used for more than ten meters, it will cause a lot of waste; reuse these materials. At the end, it is necessary to manually pull the material for feeding, and the labor intensity of the staff is too large. In the winter, when the team members operate, the close-fitting fleece will be soaked with sweat.
'I was distressed at the time, it was too hard. Can you think of ways to reduce the labor intensity of employees, but also to ensure quality and quantity, improve efficiency? ' 戚红 believes that technological innovation must be carried out, so I found the company's technology minister Zhang Jianghui. Several trials, blush and Zhang Jianghui made a small curved trailer together, installed a number of light bars on the arc, and assisted feeding through the light bar rotation. But the first innovation worker in the blush life did not buy it. An old employee in the group especially resisted: I have done this for so many years. How do I change it? I don’t worry about it. The soft and hard foam makes the workers use their own inventions. After the trial, the opposition The coworkers applauded, the small trailer not only reduced the labor intensity of the employees, but also avoided the damage to the core tablets, ensuring the quality of the products. The affirmation and support of the workers, and the confidence that the blush went down the road of innovation.
The cutting iron group has always used the traditional processing method 'trapezoidal material method'. The disadvantage of this working method is that the refilling personnel need to repeatedly turn over the sheet, and the repeated turning will not only increase the labor intensity of the workers, but also make the inside of the silicon steel sheet. The crystal lattice is distorted, deformed, and vacant, thereby reducing the magnetic permeability. The blush creatively proposes the 'parallelogram' breaking method, which removes the rewinding of the refiller and reduces the influence on the magnetic permeability of the silicon steel sheet. In this case, the raw material utilization rate has increased by 10%.
Over the years, Blush has creatively developed new methods of tailoring, cutting schemes, and tailoring shearing procedures to overcome multiple technical difficulties. Someone asked, has it been calculated how much labor intensity has been reduced by innovative workers? How much does it cost? She said frankly: 'No, the workers are their own partners. The company is the platform for their own struggle. How can they settle with the family?' But the data provided by the Tianwei Group’s finance department indicates that the blush The innovation has increased the efficiency of the company by more than 10 million yuan.
In the 40 years of reform and opening up, from the fast-moving Chinese high-speed rail to the magnificent Three Gorges Dam, the footprints made in China never stopped; from the 'Made in China' in full swing to the 'China's creation' of the first-time test, the core technology of domestic R&D has become a big country. As the most complete transformer product category and core technology in China, the largest power transmission and transformation industry base in the enterprise, Baoding Tianwei Baobian Electric Co., Ltd. continues to be the Three Gorges Hydropower, West-East Power Transmission, UHV AC and DC transmission, 100 Wanhuo Electric Power Group and other national major power projects have made outstanding contributions.
Synchronized with the country, when the 17-year-old cut-off team leader’s blush has never stopped the pace of innovation, she said: 'Only we can redouble our efforts and innovate and create, in order to practice the craftsmanship and cultivate more for the company. Manufacture talents and 'big craftsmen' to produce more quality products, so that more people fall in love with the change manufacturing, and the world is called China-made.'
