In the past 10 years, my country's fastener manufacturing technology has been intangible in the process of cooperation with foreign equipment. my country's fasteners occupy a pivotal position in the global fastener industry. However, there is still a big gap between the product types, quality levels, technical standards, resources and environmental efforts within the industry and foreign advanced levels. , mainly manifested in the double pressure of "surplus" and "shortage" in my country's fastener production, but in addition to representing advanced technology hardware equipment can be bought, the "technical time difference" outside the hardware equipment is China's fastener manufacturing technology Invisible factors and keys behind.
Although there are powerful fastener manufacturing enterprises in China, why is the utilization rate of equipment and products in use very different when foreign equipment arrives in Chinese enterprises? Where is the gap? This is what we call "technical time difference", That is, the technology gap between the technology, usage, production management and other aspects other than hardware equipment and foreign countries. According to the evaluation of the average domestic fastener manufacturing level, especially in the areas involving complex process special-shaped parts and process matching, the overall level of domestic and foreign advanced levels exists "technical time difference" of about 10 to 20 years.
"Technical jet lag" has certain background reasons.
Educational background and development experience of China's fastener industry.
One is the source of education; the other is work experience. China's current fastener professional and technical personnel, from the post-60s to the post-80s, basically "introduce, digest, absorb and improve" mode of education and work experience, it is difficult to stimulate original innovative thinking, most people do things based on "" Actionable experience”, I know it, I don’t know why, many feasible experiences are wrong or have no theoretical basis. Would it be better to do this?
In the drawing workshop of domestic fastener companies, when it comes to the "die matching plan" of the wire drawing machine, no one seems to understand it, but a very common phenomenon is when foreign experts review the "die matching plan" on the spot, they will be very Surprisingly, they found that most of the wire drawing "die matching process" of Chinese fasteners (all based on the existing rich practical experience) are logically "very confusing and unreasonable", and some of them are even completely inconsistent with the theory of metal material processing deformation , the result is of course "not necessarily infeasible but resource consumption or poor product quality", which is one of the reasons why foreign equipment is not so good in the hands of domestic users.
Disagree with the existing "technical jet lag".
Domestic fastener experts usually disagree that their technology is not advanced enough, especially large-scale fastener companies. They have worked in this industry for more than 30 years, and their full experience has become an obstacle to accepting new thinking. Denying oneself is often attributed to the fact that the equipment is not advanced enough. In fact, every scientific and technological breakthrough is a process of denying the existing existence again and again, and denying or questioning is the premise of innovation.
That is to say, if we let the current technical experts "travel" to China in the next 20 years, will they still be the industry experts of "that era"? The answer is no. This proves that the "technical jet lag" we mentioned above exists.
How to accelerate the shortening of "technical jet lag".
First of all, we should acknowledge the existence of "technical jet lag". How can we speed up the shortening of "technical jet lag"? Some people say that we have to wait for the post-90s or post-00s to become the backbone of the era, and they have innovative thinking in cultivating and educating them since childhood. What should we do now? ?Wait?
Usually, "advanced foreign technology" in our understanding refers to "advanced equipment". Although many domestic technicians have many years of experience in using foreign equipment for many years, this does not mean that they understand the design principles of equipment, and may not be able to copy Or very good absorption and improvement. During the use of the equipment, the personnel of foreign companies who are frequently contacted are basically "after-sales service" rather than technical designers, so they cannot learn the core technology.
In addition, technology and equipment are inseparable, and advanced equipment only represents a part of "advanced". Here, our understanding of technology should refer to all aspects of the product manufacturing process, including the use of equipment, conditions, material pretreatment, configuration. It is a comprehensive macro process such as programs, daily maintenance management, etc., rather than the work scope of the "technical process department" within the enterprise.
The hardware equipment representing advanced technology can be bought, but the "craft" representing software is hard to buy, and it can only be learned and accelerated!
"Technical jet lag" is not enough to catch up.
"Technical jet lag" is an objective existence. First of all, you must clear your own inherent concept, that is, the "empty cup principle", especially to recognize that you have a gap. Create learning opportunities. Fortunately, today's Industry 4.0 and "2025" made in China complement each other. Many foreign experts are standing on the "side of the jet lag". They are in the same era with us without crossing them. Four-dimensional (time) It can become three-dimensional. If we can create opportunities or take advantage of opportunities, learn every bit of technical details, get to the bottom of things, know why, and why, it is not impossible to shorten the "technical jet lag" from now on. Manufactures a surplus of low-end fasteners.
Facing the opening year of the 13th Five-Year Plan in 2016, the development and wide application of some revolutionary technologies have made the change of fastener technology an irreversible trend, which requires the improvement of the system, the role of the market, and the change of our consciousness. And the cultivation of core technology, the development and brilliance of the fastener industry is inseparable from the efforts of every industry personnel.
