On February 5, the twenty-sixth day of the lunar calendar, many enterprises in Shijiazhuang Economic and Technological Development Zone have hung red lanterns at the door.
I'm here to greet you with an early life! "Early in the morning, Su Ru, deputy dean of the Graduate School of Hebei University of Science and Technology, rushed to Heye Science and Technology Co., Ltd. I sent the analysis report to see what the company's research and development needs. ”
Heye Technology is a specialized and new "little giant" enterprise in Shijiazhuang that produces high-speed tool steel, and Su Ru is the head of the science and technology mission in the enterprise. In the past half a month, Su Ru gave up his vacation and worked overtime to complete an analysis report on the punch. This report contains a variety of punch failure case analysis, which can help users standardize the operation and extend the service life of the punch.
Next to the scanning electron microscope in the testing room, there is a row of punches of different types. "These punches are all molds made of special steel materials, which are used for stamping and shaping. Su Ru said.
The reporter carefully observed and found that these punches were damaged to varying degrees, or cracked, or deformed.
High-speed tool steels have extremely high requirements for steel strength and toughness. Su Ru told reporters that these are the preparation or use of the most problematic punch, through the detection of residual stress on the surface of the punch, you can analyze the cause of punch damage, help users find solutions, and then improve production efficiency.
Let a professor who is engaged in the research of the service damage mechanism of special steel to analyze the cause of damage to the small punch, isn't this overkill?
Don't underestimate this work. In the face of reporters' questions, You Xiaodong, director of the R&D Department of Heye Science and Technology, said, "Relying on residual stress and tissue analysis, Mr. Su helped us improve the heat treatment process, so that the average service life of the punch increased from 3,000 times to 30,000 times." ”
In October 2022, Su Ru and 5 colleagues were stationed at Heye Technology. At the first technical docking meeting, You Xiaodong raised the problem of short service life of punches.
The needs of enterprises are the direction of our research. Su Ru claimed the problem on the spot.
In the following year, Su Ru used high-end precision testing equipment such as microbeam X-ray diffractometer to analyze the residual stress distribution law on the punch surface through dozens of micron spots, find out the causes of cracking and deformation, and then track the whole process from steel inspection to blank blanking, from pre-processing to top forming, from product heat treatment to finished product testing, and find a breakthrough in improving the process.
We have carried out hundreds of experiments, not only to optimize the formula of alloying elements in smelting, but also to adjust the tempering temperature of heat treatment, which greatly improves the strength and toughness of the material, increases the processing rate of the punch by a large margin, and makes the service performance of the punch more stable. Su Ru introduced.
It is precisely because of the help of "capable people" that the pace of independent innovation of Heye Technology has become more and more firm, not only establishing the key laboratory of high-quality tool and mold materials in Hebei Province, participating in the establishment of the first batch of provincial advanced metal materials industry colleges, but also achieving a new breakthrough in the sales of high-speed tool steel, and the current international market share of products has exceeded 17%.
Mr. Su, I would like to give you a New Year's greeting in advance! The company's R&D and innovation are thanks to your help. You will continue to lead us to carry out key projects and strive for greater breakthroughs this year! When parting, You Xiaodong held Su Ru's hand tightly. (Hebei ** reporter Dong Chang).
