In recent years, China's punch press industry has achieved certain results, but we should also see the bottleneck problems encountered in the development of our country. Technological innovation has always been a flaw in the domestic press industry. Compared with the punch press bed industry in foreign countries, the punch press industry in China lags behind in the manufacturing process, and there are serious deficiencies in the technical level and operating speed. If you want to solve this problem, you must take strong countermeasures.
After the 18th National Congress was convened, with the smooth transfer of power, policies became more stable, and economic development was the last resort. The focus of the central decision-making level will shift to domestic economic growth. To achieve economic growth must first be driven by our equipment manufacturing industry, then CNC punch press will achieve rapid growth.
The market demand for domestic high-end CNC machine tools has increased, and new types of CNC machine tools have become frequent. CNC punching machine has a CNC control system, which can arbitrarily set the motion mode and speed of the slider according to the processing method. According to market changes, the future direction of domestic CNC punch press is expected to have the following models.
1. Screw type CNC punching machine is suitable for the high-precision and high-function non-cutting forming screw type servo punch press. The hydraulic motor and accumulator are used for torque control. The bottom dead point position control can reach micron level, which is energy saving and has Environmental protection requirements.
2. Crankshaft Servo Press This type of press has the characteristics of the servo press which can be arbitrarily set in the slider motion mode. At the same time, it has the torque characteristics of the ordinary mechanical press, but its working energy will not be reduced in the low speed zone.
3. Double-action forming Press multi-action forming is a powerful tool for no-cut forming. Forging forging in cold forging is an example of controlling the plastic flow of a material by controlling the motion and time diagram of multiple punches and dies. The precision and formability of the product can be improved and even the number of processes can be shortened.
4. Occlusion forging presses have a occlusive function and a coordinated function in the die structure. Other occlusion forging presses that can save piping time during mold assembly can be divided into two categories: these functions are all in the press and the upper and lower cylinders are on the punch and the coordinating mechanism is on the mold base in two forms.
5. Plate forging presses With the popularization of plate forging and forming, it is required that the forging presses can perform deep drawing or shorten the number of works. Therefore, sliders and table must be provided with cylinders.
6, gear forming punch with this method processed products, processing pressure is only 1300Mpa, tooth-shaped part of the collapse of the corners and small hair. The gears that control the formation of the material flow through the compounding process can reach JIS Class 3~4, which is very close to the high value-added non-cutting forming.
At present, the technological development of China's CNC machine tools is still not very mature, but our country has been advancing in the exploration and development in innovation. In this case, there will be better opportunities for development, thus improving their own prospects.
In recent years, China's punch press industry has achieved certain results, but we should also see the bottleneck problems encountered in the development of our country. Technological innovation has always been a flaw in the domestic press industry. Compared with the punch press bed industry in foreign countries, the punch press industry in China lags behind in the manufacturing process, and there are serious deficiencies in the technical level and operating speed. If you want to solve this problem, you must take strong countermeasures.
At present, most punching companies in China lack the awareness of independent innovation. Can't do deeper technology research and development. This restricts the development of the press. If you want to solve this phenomenon, innovation is the key, companies should increase technical support, in the punch industry to achieve the combination of development and innovation, clear future development goals, while ensuring product quality, while accelerating the development of punch technology. Because China is currently in an economically underdeveloped state, most companies have short-sighted development strategies, and technological innovation is particularly slow. Therefore, relevant government departments should give support to jointly promote the development of the punch press industry.
As an important processing tool, the punch press has an important role in the development of China's future high-tech industries. Therefore, both the enterprise and the government should do their utmost to promote the development of the punch industry in China.
The power of ordinary household electric iron is generally 300W, 400W ,500W,800W and 1000W .
Its power specifications are 300W, 400W,500W, 800W and 1000W, and the temperature control range is 60-230 ℃. The electric iron is internally equipped with a bimetallic temperature regulating switch, which automatically cuts off the power supply when the specified temperature is reached; When the temperature is lower than the specified temperature, the power supply is automatically turned on for heating. The names of various ironed fabrics are marked on the temperature control knob. When the knob stops pointing to the name of a fabric, the iron will control the temperature within the appropriate greenhouse range for ironing the fabric, which can meet the ironing requirements of nylon, synthetic fiber, silk, wool, cotton, hemp and other fiber fabrics.
