Present Status and Development of Electro – hydraulic Servo Control
China’s electro-hydraulic servo development level is still in a stage of development, although the conventional electro-hydraulic servo control technology, we have a certain development. But in the electro-hydraulic servo high-end products and application technology, we are from the developed countries of the technical angle shear level there is a big gap. Electro-hydraulic servo technology is a set of mechanical, hydraulic and automatic control in an integrated technology, to develop the domestic electro-hydraulic servo technology must be from the mechanical, hydraulic, automatic control and computer and other technical fields simultaneously.
control system
Measurement and control system With the maturity of digital control theory and the development of high-speed DSP technology. All-digital measurement and control system has become the future direction of the development of measurement and control systems. Dynamic electro-hydraulic servo digital measurement and control system, not only requires the hardware operation speed, high precision, but also requires software and digital control custom metal fabrication theory to a new breakthrough. So as to meet the electro-hydraulic servo control system, fast response, precise control, stable and reliable requirements. At present, the United States MTS TeststarII all-digital controller, the operating frequency can reach 5000 times / second, the control characteristics of the traditional PID control, based on the feed forward control, frequency reverse compensation control, amplitude control and differential pressure and other auxiliary Control characteristics. Therefore, the digital controller because of its rich computing capabilities, its control is very flexible, analog control system is unmatched. The current domestic technology mature digital dynamic controller has not yet entered the stage of industrialization, but also need to have a development process. Multi-channel, digital, multi-degree of freedom coordination technology is the key technical link in the development of simulation test technology of electro-hydraulic servo technology. Only master the multi-channel control technology, multi-degree of freedom to coordinate coupling and dual technology, in order to make our electro-hydraulic servo technology to a higher level ahead, in order to narrow the gap between foreign counterparts. To achieve this goal requires a number of high-quality technical team, from the software, hardware, digital control theory and practice, and other integrated technology to promote simultaneously.

Hydraulic parts
The overall level of domestic hydraulic parts is still relatively backward, mainly using rubber seal structure, easy to aging leakage, bulky, low integration. With the mechanical precision machining technology matures, most of the foreign seal with spherical and conical surface with the seal, simple structure, reliable sealing performance. In the future to improve the structure of the domestic hydraulic  hydraulic hole punch machine parts also need to work hard in the process, the need for a systematic improvement process. As the key element of electro-hydraulic conversion “electro-hydraulic servo valve”, is the electro-hydraulic servo control technology to enhance the future of the key link. Electro-hydraulic servo technology industry and electro-hydraulic servo valve manufacturers lack of communication and discussion, only a simple application of its ready-made products. In a sense, this also limits the domestic electro-hydraulic servo technology. In the future, we need to strengthen cooperation with the servo valve manufacturers to jointly develop servo valve products suitable for testing machine applications, and comprehensively enhance the domestic electro-hydraulic servo technology. The development and application of computer technology has promoted the improvement of electro-hydraulic drill machine for flange servo technology. It is the use of computer technology to make the electro-hydraulic servo system in the field of dynamic simulation and simulation experiments have been widely used. The application and development of multi-degree-of-freedom coordinated control and computer simulation decoupling technology have further improved the performance of multi-channel coordinated loading system and road simulation test system and promoted the wide application of electro-hydraulic servo system. It can be said that the development of electro-hydraulic servo technology and the development of computer technology are closely linked.

The rapid development of machinery industry The general situation of the machinery manufacturing industry In recent years, China’s manufacturing industry has been sustained and high-speed development, China is a manufacturing country: the world in a large number of imports of Chinese products, and China’s exports, mechanical and electrical products accounted for the majority. In the current economic cold wave and crisis, the mechanical industry has been greatly affected angle iron shear, but the total size and total output after the United States, more than Japan, ranking second in the world, exports have surpassed Germany to reach the world’s first in 2009, China Car production has surpassed the United States and ranks first in the world. China has become a real world manufacturing power. But this year the world top 500 mechanical 500, none of China selected; world machinery 100, China was selected only 9. It should be recognized that China’s manufacturing industry is big and not strong, though it is a big manufacturing country, but can not be called a manufacturing power.

Last year, China’s production of machine tools ranked first in the world, imported machine tools 5.9 billion US dollars, 1.41 billion US dollars export machine tools, machine tools import and export of over 4.49 billion US dollars, import and consumption of machine tools for 8 years ranked first in the world. In 2007, China’s CNC machine tool production 123,257 units, an increase of 32.6% over 2006. 2008 China’s CNC machine tools affected by the world economic crisis, production 122,211 units, compared with 2007 was essentially flat. China’s exports are cheap middle and low machine tools, while the import is expensive CNC and precision machine tools. Now the international economic development situation is not clear CNC beam steel drilling machine, in the face of complex and volatile domestic and international situation bevelling machine, although the first half of 2011, China’s machinery industry is in good shape, but the trend is not optimistic. China and the international manufacturing power compared to the technology there is still a big gap, to study and improve product quality, increase the high-end products, improve the manufacturing process, and strive to innovate in the post-crisis era, China’s machine tool industry and strive to achieve from the machine tool Power to the powerful transformation of the machine. If China’s hardware machinery industry in 2012 to achieve further development, must be technically hard, research and development to a more sophisticated high-quality high-tech products.

Precision punch press equipment and noise reduction function of the introduction

Dec 09
2016

Most of the existing precision punch press equipment is punched in the punch body installed on the beam installation hole, hit the material beam pierced in the mounting hole and its both ends of the extension hole, fixed in the top of the fight beam The punching bar can be moved up and down in the mounting hole and hit the stripper bar; the punching die equipped with the feeding rod is fixed on the slide block and the pressing mold can be pushed up by the slider to move upwardly against the striking material beam; The two ends of the striking beam are respectively impacted by the striker to produce the impact force.

The impact force is transmitted to the feeding rod on the punching die through the striking material beam and the slider, and the feeding rod is moved under the action of the impact force, The material in the mold is ejected. Just hit the material during the operation, hit the material hit the beam bar hit the feed bar material will have a great ‘bang’ impact sound busbar punching machine, and so the material down, hit the beam back to the punch when the punch body, resulting in very Large ‘bang’ impact sound, often in this great ‘bang bang’ noise, it will inevitably lead to stamping workers produce irritable mood. Moreover, the punch is now precision punching punch and fuselage body are manufactured separately CNC angle mark, while the punch body fuselage tolerance is relatively large Marking on Metals, resulting in punching machine body installation hole and hit the beam with the error is quite large, single-sided gap Can reach 5mm, when the press work, even if the feeding device can not afford to play the role of material, playing the beam will be in the precision punch under the vibration of non-stop and collision with the punch body noise, and some stamping workers in order to avoid Noise, then put the beam to break down the material, often demolished, hard time and effort, but also damage the beam. In order to solve the problem of excessive striking impact of the material feeding device, Shore Machinery improved the original punching device, and the improved stripping device hit the striking beam at both ends of the material beam The elastic block is made of rubber with the hardness of Shore; at the same time, in order to reduce the pressure of the striker against the impact piece of the first elastic piece, The cross section of the disc is larger than the cross section of the stripper bar; when the feeding device can not afford the material feeding effect, in order to make the striking material beam not in the punch press The second elastic block is made of the rubber with the hardness of Shore, and the second elastic piece is fixed by the rubber elasticity of the Shore, A fundamental solution to the feeding device when the use of excessive noise problems.
