With the rapid development of socialism in our country, the development of all walks of life in our country has made great progress. In the context of this era, my country's agriculture, industry, and service industries continue to develop in the direction of high technology and automation. Especially in the Internet era, people are becoming more and more dependent on the convenience that high-tech terminals bring to life, and they increasingly hope to continuously improve the mechanical equipment commonly used in life through advanced technology to improve the quality of life of contemporary residents in our country. Therefore, it can be found that under the background of this era, the development of my country's machinery manufacturing automation industry will effectively promote the improvement of people's quality of life. The urgent demand of Chinese residents to improve their quality of life has become the main contradiction in my country's socio-economic development level in the new era. Therefore, in order to better promote the resolution of this contradiction and improve the relationship between our country's national government, society and our residents, it has become very important and necessary to conduct research on the machinery manufacturing automation industry.
1. Characteristics of mechanical manufacturing technology
1.1 System Engineering
Nowadays, in modern machinery manufacturing technology, computer technology, automation technology, new material development technology, etc. have been gradually used. Among them, the product design and sales network of system engineering have been very mature in applying modern metals. Compared with the traditional machinery manufacturing industry, machinery manufacturing can use high-paying technology as a basis and is a high-paying industry, and the use of new technologies can also be used throughout the entire production process.
1.2 Comprehensive technology
The use of advanced manufacturing technology can effectively improve the competitiveness of enterprises, and can also effectively enhance the country's economic strength. Therefore, the machinery manufacturing industry involves various aspects such as market research and sales methods, and is not simply limited to manufacturing products themselves. The machinery manufacturing industry needs to effectively integrate these links and develop these links in a centralized manner, while manufacturing The integration of sales and marketing can effectively improve the competitiveness of enterprises and ultimately improve the economic benefits of enterprises.
1.3 Reflects the factors of market competition
In order to improve the competitiveness of enterprises in the market, machinery manufacturing enterprises must improve their production efficiency of products. Nowadays, with the continuous development of economies around the world, global economic integration has accelerated. After the 1990s, if the manufacturing industry wants to improve its market competitiveness, it must comprehensively consider time, quality and cost. Nowadays, what we think of as advanced manufacturing technology is that it can simultaneously improve product quality and reduce production costs on the premise of ensuring efficient production, and organically combine the three.
2. Development status of machinery manufacturing technology
2.1 The design scheme is backward
Judging from the development history of Western developed countries, they have all experienced the reforms of the steam age and the electric age, so they have very mature craftsmanship. In addition, the manufacturing development period of Western developed countries is also higher than that of our country. Compared with Western industrial powers, my country's manufacturing technology is relatively rough and lacks a certain level of modernization. Many cutting-edge technologies are still in the development stage. Among many manufacturing companies in my country, their working model is still Although some enterprises in farm workshops already have certain mechanical technology, they are still very lacking in high and new technologies.
2.2 The manufacturing industry system is backward
In the process of developing original capital, Western industrial powers have scientifically established and continuously improved industry systems. In addition, manufacturing enterprises within the systems of Western industrial powers also have certain standards. In the management process of the enterprise, computer management is mainly used, and the operation of the production system is also very efficient, with an update cycle for delivering orders. Compared with Western industrial powers, many enterprises in our country are still in the exploratory stage of management models, and only a small number of enterprises can use computer management models to manage enterprises.
2.3 Low degree of automation
Nowadays, among enterprises in Western developed countries, fully automatic machinery such as computer integrated systems has been effectively popularized. The popularization of these computer systems has enabled manufacturing enterprises to conduct automated and intelligent production, which has greatly improved The production efficiency of the enterprise can be effectively guaranteed, and the production quality can be effectively guaranteed. In our country, many machinery manufacturing companies still use flexible manufacturing systems, and some private companies even use rigid automation and rely heavily on manual management.
3. Development trends of my country’s machinery manufacturing technology
Advanced manufacturing technology is the latest development stage of manufacturing technology. It is developed from traditional manufacturing technology. It not only maintains the effective elements of past manufacturing technology, but also continuously absorbs various high-tech achievements and penetrates into all areas of product production. and its entire process. In the 1980s, with the invention and use of scanning microscopes, humankind's ability to understand and transform the world entered the nanoscale. Nanotechnology refers to the realization of nanoscale precision, and is a method of studying atomic and molecular structures and material properties at the nanoscale. and interaction and movement, and use this technology to serve human beings. Nanotechnology has had a great impact on manufacturing. Its application scope will be very wide, including nanomaterial technology, nanoprocessing technology, nanoassembly technology and Nano-measurement technology, etc.
The processing accuracy of ultra-precision machining has reached the nanometer level in 2000. The molecular beam growth technology, ion implantation technology, material synthesis, and scanning tunneling engineering (STE) developed in the early 21st century can enable the processing accuracy to reach 0.0003-0.0001μm. Now precision Engineering is approaching its ultimate goal—processing with atomic-level precision, that is, processing at the moving atomic level can be achieved.
The development of modern machinery manufacturing technology is mainly reflected in two directions: first, precision engineering technology, represented by the cutting-edge parts of ultra-precision machining, micro-machining, and nanotechnology, will enter the era of micro-mechanical electronics technology and micro-robots; second, The high degree of automation in mechanical manufacturing is represented by the further development of CIMS and agile manufacturing.
3.1 Precision forming technology Forming manufacturing technology includes casting, welding, plastic processing, etc. Precision forming technologies include: precision casting (wet film precision forming casting, rigid precision forming casting, high-precision core making), precision forging (cold wet precision forming, precision blanking), precision thermoplastic forming, precision welding and cutting, etc.
3.2 Intangible cutting processing The main application field of cutting fluid-free machining is the machining industry. Cutting fluid-free machining simplifies the process, reduces costs and eliminates a series of problems caused by coolant, such as waste liquid discharge and recycling.
3.3 Rapid prototyping technology Rapid prototyping part manufacturing technology (RPM), its design breaks through the principle of material removal used in traditional processing technology, and adopts the principle of addition and accumulation. Its representative technologies include layered solid manufacturing (LOM), fused deposition manufacturing (FDM) and so on.
Because the above processes and technologies not only reduce the consumption of raw materials and energy, shorten the development cycle, and reduce costs, but also some process improvements protect the environment, they are called green manufacturing processes. Green manufacturing is the embodiment of the sustainable development of human society in the manufacturing industry.
