After the industry development seminar on November 10-11, the association drafted the document “Inclusion of the super-hard materials and products industry in the “Proposals for High-tech Fields Supported by the State†(hereinafter referred to as “Recommendationsâ€). Chairman Zhu Feng and Secretary-General Li Zhihong gave a speech to the National People's Congress and Chairman of Henan Huanghe Cyclone Company Qiao Qiusheng, and submitted the "Proposal" document, asking them to explicitly include superhard materials and products in the national key as a deputy to the National People's Congress. In support of the high-tech field proposal, Chairman Qiao Qiusheng happily accepted the "Proposal" and contacted potential representatives to write a proposal to the Standing Committee of the National People's Congress. Secretary-General Li Zhihong also invited Professor Zou Guangtian, an academician of the Chinese Academy of Sciences and a key laboratory of the National Superhard Materials, to report to the Ministry of Science and Technology of Beijing on December 15 and to organize the 4th Zhengzhou International Superhard Materials and Products. Shao Liqin, former director of the Ministry of Science and Technology of the Ministry of Science and Technology, made a detailed report and submitted the "Proposal". Director Shao not only strongly supported our proposal, but also promised to help the industry urge the relevant leaders of the Ministry of Science and Technology to consider adopting our proposal as soon as possible. During his stay in Beijing, on December 16, Secretary Zou and Secretary-General Li Zhihong also paid a special visit to the Director General of the Machine Tool Industry Association, Wu Bolin, to explain the situation to the Director-General Wu, submit the proposal and ask the "Proposal" to be published in the name of the General Conference. Send it to relevant government agencies such as the Ministry of Science and Technology. Director-General Wu accepted our proposal very happily. The "Proposal" is now submitted to the relevant government agencies such as the Ministry of Science and Technology in the name of the General Conference. On December 16th, Secretary-General Li Zhihong also made a special trip to the vice president unit, the Beijing Institute of Artificial Crystals, to report to the National Committee of the Chinese People's Political Consultative Conference, the Chinese Academy of Engineering, Shen Dezhong, and the dean, vice president and secretary of the institute, and submitted the report. The proposal, with the strong support of Academician Shen and the leaders of the hospital, Academician Shen has happily signed the "Proposal".
Under the active efforts and personal activities of the Vice President of the Crystal Institute, Zhou Lianke, we have repeatedly tried to pass the national “973†project chief scientist, the 16th National Congress, the 17th Party Congress, the Chinese Academy of Engineering, and the South China Institute from December 17th to 24th. Professor Huang Boyun, the assistant of the university president, Professor Xiong Xiang reported the situation to the academician Huang in detail, got the affirmation and support of the academician Huang, and solemnly signed the "Proposal"!
The "Recommendations" signed by the chief scientist Huang Boyun, Academician Zou Guangtian and Academician Shen Dezhong have been submitted to the relevant leaders of the Ministry of Science and Technology.
On December 17, when the director of the Torch Center of the Ministry of Science and Technology, Liang Gui and his entourage, went to Henan to investigate the identification of high-tech enterprises, the director of the board of directors immediately contacted the deputy director of the high-tech enterprise of Henan Science and Technology Department to report to him. I have participated in the "High-tech Enterprise Certification Management Work Symposium" and the opportunity to report to Director Liang. The chairman of the board of directors and the secretary-general attended the meeting and reported the situation to Director Liang and submitted the "Proposal." At the meeting, Secretary-General Li Zhihong introduced the technical development of the super-hard materials industry, its status and influence in the international arena to the leaders of the party, the director of the Yellow River and the leaders of the science and technology bureaus of various cities, and should be included in the high-tech field to give priority support. Waiting for the situation. During the speech of Secretary-General Li Zhihong, Director Liang interjected: "It seems that the "except for the six-sided diamond" should be deleted!
In his concluding remarks at the end of the meeting, Director Liang pointed out: "I can say responsibly, the problems that everyone will reflect, we will study and solve as soon as possible after returning to Beijing!..."
The association is still paying close attention to the development of the situation, and is still working hard to urge the country to formally include super-hard materials and products in the high-tech fields supported by the state as soon as possible: to solve the urgent need for the enterprises in the industry to encounter difficulties in applying for high-tech enterprises! Strive for a more relaxed policy environment for industry enterprises, and accelerate the pace of achieving a super-hard material power!
Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
