How to make the CNC mold industry develop the technical foundation

As we all know, the improvement of technology in industrial development is the most important part. How to make the development of the industry better on the basis of technology is a problem that all parties should pay attention to.

At present, numerical control is the focus of industrial development in the industrial field and the inevitable trend of industrial development. With the continuous improvement of technology, CNC technology will gradually become popular in mold machinery and equipment.

The NC generation equipment innovation project is to promote the application of digital control technology in various types of equipment, integrate and innovate a batch of numerical control equipment, and realize the upgrading of equipment performance and function, and then promote the transformation and upgrading of the equipment manufacturing industry. As early as the beginning of 2011, eight academicians put forward proposals for the implementation of the “Digital Generation First Generation Machinery Product Innovation Application Demonstration Project”, which was highly valued by relevant state departments. In the first half of 2012, the “Digital Generation First Generation Machinery Product Innovation Application Demonstration Project” was released and implemented. In this context, the "CNC Generation Equipment Innovation Engineering Action Plan" was released soon. The development of CNC generation equipment manufacturing has been clearly visible. In the past, the importance of numerical control in 2013 has become more and more important. In the future industrial development, CNC machinery is inevitably the most important aspect.

The "Plan" shows that in order to achieve the goal, five major actions will be organized and implemented: CNC technology development and promotion service platform construction, CNC technology development and industrialization, CNC equipment integration innovation, CNC equipment demonstration and promotion, CNC equipment technical specifications and standard system construction. . Among them, PLC, man-machine interface, control software, inverter, servo drive, energy-saving motor and other automation technologies are the key development targets, and will enjoy the policy rain.

Among them, we must first improve the quality and reliability of a wide range of general-purpose programmable controllers, human-machine interface devices, integrated controllers and software packages.

Secondly, it is necessary to strengthen the development of professional application software and hardware combined with the manufacturing process of typical industries to meet the needs of the development of CNC equipment in the industry.

Focus on the development of servo drives and motors required for various CNC devices, such as digital servo control systems, network distributed servo systems and other servo drives, energy-saving motors and variable-frequency motors.

Focus on the development of high-power, high-performance variable frequency speed control system, traction frequency control device and special speed control frequency control device.

Focus on textile machinery, plastics and rubber processing machinery, small and medium-sized machine tools and basic manufacturing equipment, printing machinery, packaging machinery, food processing machinery, pharmaceutical machinery, energy-efficient products, etc., to achieve numerical control integrated development.

The numerical control of equipment has become an important development trend. Industrial developed countries attach great importance to the development of high-tech equipment. After more than a decade of development in China's equipment manufacturing industry, the proportion of CNC equipment in the domestic market has been continuously improved, and has formed a strong innovation capability. a more solid foundation. The release and implementation of the Plan will further advance the numerical control of equipment. Luo Baihui said that China's equipment manufacturing can achieve mold manufacturing, metal processing and other typical industries in 2020 equipment numerical control rate reached 70%. The realization of numerical control equipment development and extension services capabilities significantly enhanced, continue to train a large number of can operate on CNC equipment and Maintenance skills. Achieve the wide application of numerical control equipment, increase the production efficiency of key application areas by more than 20%, and reduce energy and resource consumption by more than 30%.

Why is the air dry in winter?

What we call humidity is divided into two kinds, absolute humidity and relative humidity.

Absolute humidity refers to the amount of water molecules per cubic meter of air.

Relative humidity refers to the ratio between "absolute humidity" and "saturation humidity".

"Saturation humidity" refers to the absolute humidity required for the water vapor in the atmosphere to reach saturation at a certain temperature. Saturation humidity is also closely related to temperature. The higher the temperature, the greater its value.

The drying or wetting we usually feel does not have a great relationship with absolute humidity, but mainly depends on relative humidity. Therefore, this issue should be discussed as follows:

On the one hand, when the temperature is low in winter and the saturated vapor pressure is small, the absolute humidity of the air is small.

On the other hand, when the temperature is low in winter, the value of saturated humidity is also small. When the absolute humidity is the same, the relative humidity is greater.

Generally speaking, there are positive and negative effects of temperature on humidity. Which role plays a major role should be discussed according to the actual situation.

In some areas it gets dry in winter, while in others it may get wet. The temperature is low in winter. Even if the relative humidity is 100%, the water vapor content is still very low. After we inhale air, the air is heated to body temperature, and the relative humidity will become very low, so we will feel dry. The air we exhale is basically saturated steam at body temperature, so we consume a lot of water when we breathe.

The air near the skin will also be heated, so the moisture of the skin is also easy to evaporate

The doctor suggested that an Aroma Diffuser should be placed indoors, which can effectively and immediately solve the problem of indoor air drying, humidify the air and solve the problem of air drying. The ultrasonic aroma diffuser should be used, and the fog should be sprayed out through vibration
