The wall thickness of the column is about 1--2mm, and the sheet is formed by cold bending and cold rolling. The utility model has the advantages of simple structure, regular semi-elliptical shape and convenient installation. Palisade Fence Making Machine hook on the cylinder is divided into several parts by the notch and evenly distributed on both sides of the cylinder along the longitudinal direction of the cylinder. The curved plate in the hook plate is tangent to the straight edge of the elliptical cylinder, which effectively prevents the split from being opened and ensures the safety of the guardrail.

It is understood that in recent years, due to the depressed economic environment and slower growth rate, almost all industries have been affected, and the machine tool industry as an upstream equipment manufacturing industry has also been dragged into the "winter." As for the machine tool industry, which has continued its technical and strategic continuation of the old road and has not sought to change its development ideas from the root, it has become a general trend through transformation, upgrading and development of composite products.
Nowadays, China has become the world's largest machine tool country. After more than 30 years of development, the domestic CNC machine tools have basically matured in terms of industrial technology. The product range is complete, and the performance and quality have been recognized by various countries in the world. As the "master" of industrial manufacturing, machine tools have a very important significance for the development of the national industry.
Since the beginning of this year, orders for domestic machine tool products have decreased significantly. In a stagnant market environment, the increase in production costs has caused the profits of machine tool companies to decline, and machine tool companies have also shouldered tremendous pressure to enter the transition period. China Machine Tool Network believes that the main reason is that "some Chinese companies are apt to greed for perfection, and they always want to achieve a large scale, rather than first consider how strong the company can be, which in turn leads to a greater impact on companies when the economy is depressed."
The downturn in the market has caused domestic companies eager to develop large-scale developments to suffer, but the bigger impact is not limited to this. According to the “Twelfth Five-Year†development plan of the machine tool industry announced by the state, it is estimated that by 2015, China's machine tool industry will achieve a total industrial output value of 800 billion yuan, and the annual output of CNC machine tools will exceed 250,000 units, and the domestic market share will reach over 70%. .
When the global market was sluggish, the huge gap in the Chinese market was particularly valuable. Many foreign companies seemed to have seen business opportunities and marched into the Chinese market. It is understood that European companies such as TRUMPF, Emma, ​​INDEX, GF, etc. have all set a clear Chinese market strategy and increase investment to seize market share.
In fact, in today’s increasingly competitive industrial end-products, in the industrial production chain, the competition in the upstream industrial chain of unknown parts such as machinery parts, metal processing, and parts and components is even more fierce. In the industrial machinery, electronic products, and aerospace industries, the parts processing and casting technologies at the source are sophisticated, and compared with the international manufacturers that provide key technologies for them, most companies active in the upstream are also hidden. After numerous auras.
The decrease in product orders for domestic machine tool companies appears to be due to the sluggish global manufacturing industry. More reasons are due to the impact of foreign countries on the domestic market, especially the weakness of domestic companies in key technology fields, which have made domestic companies in a depressed environment. Hidden competition. According to official data from the TRUMPF Group, as of now, it has 60 branches and offices in all countries in Europe, as well as in North and South America and Asia. In 2011, its sales amounted to EUR 2.33 billion, a year-on-year increase of 15%, which exceeded its highest sales record before the financial crisis. The rapid sales growth proves the above conclusions.
In recent years, the pace of upgrading domestic machine tool products has accelerated, technological research and development efforts have continued to increase, and innovation results have been frequent. However, compared with the international market, domestic machine tools still have a large gap in terms of reliability and density stability. This has nothing to do with the domestic machine hardware, but the key lies in the CNC system.
It is understood that the numerical control system has been known as the central nervous system of CNC systems, has always been the key to hinder the development of China's CNC field. After many years of market competition, the survival of the fittest has formed a monopoly by Japanese Fanuc companies that monopolize the world market by 50% and Germany’s Siemens by 25%. Therefore, there are serious irrational phenomena in the industrial chain industrial structure of the domestic industry. The numerical control system, functional components and tools show a serious lag with respect to the development of the host. Compared to the host, the numerical control system, functional components and tools are The "strong" and "great" aspects are unsatisfactory, and there is still a big gap between the current world level and even the companies in Taiwan.
