China Machinery Industry Federation predicts that the growth rate of the major economic indicators of the machinery industry will continue to decline in 2012, the growth rate of production and sales is expected to be about 18%, and the profit growth rate is expected to be about 12%.
National Bureau of Statistics data show that in 2011 the total industrial output value of machinery industry reached 16.89 trillion yuan, an increase of 25.06% year-on-year. The monthly growth rate of the output value of machinery industry has fallen rapidly. Among them, the production and sales of automobiles were 18.42 million and 18.51 million, respectively, an increase of 0.84% ​​and 2.45% year-on-year respectively, and the growth rate of production and sales was the lowest in nearly 13 years.
"The fall in growth rate is not only reflected in the industrial output value, but the growth rate of profits has fallen even further." Cai Weici, vice president of the China Federation of Machinery Industry, said that the profit growth rate fell rapidly in the first 11 months of 2011, a substantial increase over the previous year Falling 34%, despite the rebound in December, the industry's efficiency is still declining.
In 2012, influenced by the economic environment at home and abroad, the unstable and uncertain factors in the economic operation of China's machinery industry are still numerous, and the problems and difficulties faced continue to gather.
Dong Yang, secretary-general of the China Association of Automobile Manufacturers, said that profits have fallen significantly faster than production and sales, which is a point worth paying attention to. Deterioration of efficiency and difficulty in operation reflect that the industrial structure of China's machinery industry cannot adapt to changes in demand. Overcapacity occurs at the low end of the industry chain, and there is still a huge gap between the high-end equipment and the world's advanced level.
According to the data from the China Federation of Machinery Industry, the import value of China's machinery industry reached 309.4 billion U.S. dollars in 2011, an increase of 21.18% over the previous year. Although the machinery industry’s foreign trade achieved a surplus of about 12.4 billion U.S. dollars, it is mainly due to the low value of the industry chain. End of the processing trade.
“China's machinery industry has a serious excess of processing capacity, and the upgrading of its industrial structure is imminent.†Cai Weici said that in 2012, he will be committed to promoting the adjustment and upgrading of the industrial structure of the machinery industry, transforming the general processing capacity that has been seriously oversupplied, and upgrading into a supply that is still in short supply. High-end production capacity enhances the long-term development of the industry.
China Federation of Machinery Industry said that in 2012, it will vigorously increase the high-end equipment independent innovation capability and market share, improve the energy efficiency index of the product, accelerate the bottleneck of breakthroughs in key basic parts, basic processes and basic materials, and expand investment from general production capacity to Cultivate the direction of innovation.
It is expected that the growth rate of major economic indicators of China's machinery industry will continue to decline in 2012, and the major economic indicators of the machinery industry will show a trend of low level before and after the end of the first quarter or second quarter. The growth rate will be renewed thereafter. Stabilize. The annual production and sales growth rate is expected to be around 18%, and the profit growth rate is about 12%, which is lower than the growth rate of production and sales; the export growth rate is around 15%.
Turning rolls refers to the use of welding pieces and the friction between the active roller to drive the cylindrical welding device rotation device. Self-adjusting turning roller for circular tube welding, the distance between the rollers can be adjusted according to the size of the cylinder, a variety of specifications for the user to choose the turning roller.
As per the market demanding, we have developed and designed kinds series of turning rolls to satisfy the customer`s requests, such as KT series adjustable turning rolls, KTS serise manual adjustable turning rolls, KTD series electric adjustable turning rolls, KTF series heavy duty anti-creep adjustable turning rolls and ZT series self-aligning turning rolls. As per the customer`s requests, we can design ang manufacture non-standard turning rolls, such as turning rolls with trolley, inclining turning rolls, hydrulic elevation turning rolls and assembly turning rolls and so on.
KT Series Adjustable Welding Turning Rolls
Composition and characteristics of the welding turning roller
1 The KT adjustable turning rolls include one power bed and one idle bed.The turning rolls below 40T adopt helical-worm &cycloidal pin wheel decelerator,and over 40T adopt cycloidal pin wheel or helical-worm decelerator.
2 The series turning rolls adopts screw to adjust,available for changes of workpiece diameter,simple structure and economy
3 The wheels are new combination style ,one rubber wheel and two steel wheels,with big load capacity ,big friction,strong drive and glue force
4 Imported transducer realized the stepless regulation with wide speed range ,high precision and big starting moment
5 The control system has the synchronized linkage interface with manipopulator and has remote controller ,easy and reliable.
