Especially in sheet metal processing equipment, many companies can provide composite machining, processing unit, automated production lines and flexible production lines; wide range of large sheet metal three-piece - CNC turret punching machine, bending machine., Shearing machine, its performance have reached the international advanced level. CNC turret punch annual sales in 2010 over 2000, the annual growth of more than 20%.
Of pipeline construction, large-scale construction machinery, shipbuilding, and vehicle manufacturers to promote China\\ s large heavy-duty CNC cutting and folding equipment, profile bending equipment, heavy-duty rolling machine, ship plate presses, large multi-station presses such as a large number of international advanced level of new, unique, and the advent of the forging equipment.
New te chnology and equipment for sheet metal processing - CNC laser cutting machines is growing rapidly, China\\ s slightly the size of sheet metal machinery manufacturers have developed a laser cutting machine. In 2010, China\\ s production of kilowatt high power laser cutting machine of more than 1000 units, the rapid growth of the highlights of our sheet metal machinery. Laser cutting machine host morphology, auxiliary equipment, the workpiece, the use of the occasion and CNC punching and shearing machine, laser cutting machine is classified as forging equipment to the centralized management.
Currently, Jinan, Shandong, Jiangsu Yangzhou has become a gathering area of ??sheet metal machinery industry in China, Overall, the ability to innovate, the leading domestic level, have good development prospects.
\"Eleventh Five-Year\" since the new process-oriented to meet the special struc ture of the new process requirements, the special features of the forging equipment are also emerging. For example, isothermal forging equipment, hot stamping equipment, electromagnetic forming machine, special materials forging equipment and so on.
The rapid development of power generation equipment, aircraft, ships, military aircraft, aerospace vehicles, have greatly promoted the big heavy forging, extrusion equipment advances, making China owns heavy-duty free forging hydraulic press, heavy forging hydraulic press tonnage, the largest number of countries. Moreover, the forging hydraulic press tonnage will continue to refresh.
Program-controlled hydraulic hammer, and equipment in energy saving, environmental protection, NC on the development direction of the tremendous progress of the forging hammer class. Similarly, the screw press with CNC technology, combined with advanced switched reluctance motor technology, the fight against energy, lower dead point positio n is precisely controlled electric screw press. At the same time, China has been able to manufacture heavy-duty automatic control of the laser measurement grind Rolling ring rolling machine, grind rolling diameter of 10m ring. In addition, CNC bending machine, riveting machine, spinning machine, swing mill, radial forging machines and other small categories of products have a large number of business development, product level has reached international advanced level.
Beginning to bear results of industrial upgrading
For foundry machinery industry, Liu Jiaxu concluded that the \"Eleventh Five-Year\" period, the industry maintained a rapid development momentum, technological advances have made the foundry machinery industry changed in the past the lower end of the \"stupid thick black\" image.
Association statistics show that in 2010 the industrial output value of foundry machinery industry in China hit a record high, but the casting machine ry NC is still small. From an export point of view, foundry machinery industry exports about $ 100,000,000, the export volume of 1500 units, including numerical control products accounted for less than 20%. The view from our entire machine tool industry, foundry machinery exports accounted for a very small, the overall technical level of the industry to develop a long way to go. From the import situation, foundry machinery industry imports more than two hundred million U.S. dollars, and imports about 500. \"Eleventh Five-Year\" period, the import and export of foundry machinery industry presents the unstable situation, the situation had appeared for three consecutive years of substantial decline in imports and exports fell sharply. Foundry machinery industry by the national policy and industry situation is very obvious.
\"Eleventh Five-Year\" period, foundry machinery industry enterprises have developed rapidly, leading level the Jinan traditional st rengths such as casting and forging of the enterprises to maintain, the Baoding Virgin, Tianjin Hunter caster enterprise progress, the strong momentum of development. The Baoding Virgin, for example, the \"Eleventh Five-Year\" period has become the fastest growing five years, its output value of the development from the beginning of the period about 200 million yuan to 700 million yuan.
The information shows that the casting output in China reached 39.6 million tons in 2010, the output value of more than 400 billion yuan, casting production for 11 consecutive years, ranking first in the world. Most of the casting has been independent production, only a handful of high-end castings need to be imported. At the same time, domestic casting scrap rate decreased significantly, casting dimensional accuracy, surface roughness, and other key indicators have reached international advanced level, the technical level of the export of castings has been greatly improved. \& quot;Eleventh Five-Year\" since the country has a number of casting enterprises in the scale and technical level to approach and reach the world advanced level, and a significant advantage in international competition.
Domestic castings able to achieve gratifying results, and behind them is inseparable from the continuous improvement of the level of casting machinery, as well as market share continues to improve support and protection. \"Eleventh Five-Year\" period, China\\ s foundry machinery industry enterprises through technology introduction, digestion and absorption, independent innovation, and constantly develop cost-effective foundry machinery, basically meet the demand of the domestic high-end casting production enterprises. In this process, the professional level of continuous improvement, which bring about the improvement of the rate of raising the level of product technology and product NC, specialized production superiority has been further re flected. At the same time, energy conservation, safety and environmental protection concept of \"green cast\" in the foundry industry is increasingly strengthened.
Since the \"Eleventh Five-Year\", through the tireless efforts of the industries and enterprises, China\\ s level of casting machinery has been greatly improved with a high level of foundry machinery products, have developed a Chinese foundry machinery industry in the future further development has laid a good foundation. The production of complete sets of equipment such as large resin sand casting has been basically meet domestic market demand, the situation changed in the past mainly relied on imports; have been able to produce a casting automatic production line with a high level, reaching the level of partial substitution of imports, partly change The car engine cylinder block, cylinder head castings to be imported; In a ddition, the high level of automatic core making machine, automatic fettling machines, automatic sand processing machines, automatic die-casting machine and precision casting equipment, and other casting machinery, domestic caster basic can be manufactured.
