Investment project machinery key parts area best time
Globally, the annexation and reorganization of enterprises increased, the degree of concentration of production and production specialization of degree rise ceaselessly, more and more enterprises become the assembly plant, engine, drive system, hydraulic system, control system basically to professional factory production. Such as the production of engine of American CUMMINS company, DEULTS company of Germany, the production of transmission parts of the German company ZF, American ALLISON company, the production of hydraulic parts of the German REXROTH company, American companies such as SAUER increasingly rapid development; is in the giant enterprises in integrated.
China's engineering machinery parts and components industry exists all the time " large enterprises are unwilling to do, small businesses do not" features. In order to solve parts backward current situation, Xugong, willow worker, Zoomlion and other well-known engineering machinery leading enterprises started to increase the intensity of research and development components. Engineering machinery parts engineering machinery product development is the key foundation, support and restrict bottleneck, when the project machine develops to a certain stage, industry of high technology research gathered in the main engine, hydraulic, transmission and control technology of key parts. Master and rely on high quality, unique key components manufacturers seeking to become" one branch alone beautiful" strategy of. Luo Baihui said the association, the industry enterprises should lead the formation of the alliance, the key parts to undertake the technology tackles key problem. Usually, the mechanical parts of the path of development has the following three.
One, Chinese enterprises through the master overseas factories holding power, in order to enhance technical ability this kind of example is Zoomlion acquisition of Italy CIFA company, the first Beijing machine tool plant acquired the German Wade West Coburg company, Shenyang machine tool group and Germany such as heath. But to acquire Chinese companies, must after years of development, with the corresponding financial and management experience can take place.
Two joint venture joint venture, but not necessarily able to obtain key technology, foreign companies have many years of concentrated study of mechanical technology, surrendered to the Chinese situation very rare. Moreover, in many techniques have been a monopoly situation, overseas enterprises not to enter China technology.
Three, rely on independent R & D at present, focus on mining equipment manufacturing of Taiyuan heavy industry, development of engine parts and components production Jianghuai force, bearing the Pegasus shares, axis Institute of science and technology, are in constant input technology content of foundation research. In addition to some do parts of the enterprise, machine manufacturing enterprises will focus on the core components of the production. Because of the basic components in the development, not only related to the whole enterprise to reduce procurement costs, but also in other aspects.
China Construction Machinery Industry Association Secretary-General Su Meng in the" Summit Forum on China Construction Machinery Market during the" disclosed, two sets of support scheme will be 20 MPa boundaries, above 20 MPa and the following parts will adopt different policies to support the. MPA refers to engineering machinery parts can bear the pressure of work. China Construction Machinery Industry in 10 years to obtain rapid development, production value of entire 2010 industry is expected to exceed 400000000000 yuan. According to industry program, to 2015, engineering machinery industry output value will exceed 900000000000 yuan. So, industry of machinery of our country project further development is constrained by the key parts. It includes hydraulic parts, transmission system and other key components most need to be imported from abroad, this causes the domestic enterprises high production costs, lack of international competitiveness.
The basis of the high-end technology in domestic, the supporting parts of large quantities of equipment and technologies will gradually mature. For example, willow worker from abroad in the" transmission" of joint-stock production, as the gearbox supporting domestic casting and heat treatment technology also obtained the full development. The enterprises supporting base to keep up with, can help the company to reduce inventory and occupation of funds.
While there are dozens of companies like caterpillar engineering machinery factory, but the power shift gearbox was concentrated in the East Peoria company owned factory production. In this way, the box processing the widespread use of flexible production line, flexible processing unit, processing gear, a planetary wheel frame processing, clutch shell processing and heat treatment of gear, adopt high performance equipment. The plant hydraulic cylinder in Julius factories, drive axle is concentrated in the Austrian Rolland factory. Therefore, Luo Baihui thought that the domestic person association of construction machinery spare parts manufacturers to seek a breakthrough in the following aspects:
1, pay attention to the key components and host integration design, and further enhance the components standardization and generalization rate, maximally simplified repair.
In 2, local production, shorten the ordering and delivery time, production is close to the user, through specialized production to make the key parts and components manufacturing form a reasonable economic dimensions at the same time ensure parts quality and relies on components to realize the enterprises technological characteristics.
In China, the current construction machinery spare parts manufacturers still only a respective busy staking, if two parties fight. While in traditional models, such as loaders, bulldozers and other key components, using its own size and means of marketing, have the absolute competitive advantage; but in such as the paver, concrete machinery used imported components, combined with many years of the introduction of technology on the basis of the assimilation and innovation. Produce path dependence; in some large products, high intelligent level products and the emerging professional products, such as more than 220 horsepower bulldozer, engineering drill and so on, is not competitive; especially in the typical earthmoving equipment -- excavator, since the control technology and key parts and components manufacturing technology of scarcity, market share almost.
Industry of machinery of our country project through the gold for ten years, has now developed for engineering machinery manufacturing industry big country, many enterprises in overseas markets occupy a space for one person in our country in succession, leading enterprises merger and acquisition of overseas well-known enterprises, but also can not cover up barrier China from manufacturing to made in malpractice -- engineering machine parts. Suzi Meng said, during the 12th five-year plan, project machinery industry will focus on resolving the problem of key parts in short board. He said, at present is the investment of engineering machinery key parts area best time.
