1. general situation of forging and pressing machinery industry
In recent years, China's Forging Machinery volume forming equipment and sheet metal processing equipment have developed in parallel. All kinds of small and medium sized forging machinery have complete specifications, increased quantity, the overall level and the numerical control rate have been improved quickly, which meet the needs of the national economic development and have been exported.
2. industry macro data
In 2010, 261488 sets of domestic forging machine tools were increased by 18%, and the gross output value of the forging machinery was 40 billion 750 million yuan, with a year-on-year increase of 42.2% for 30% of the total output value of the machine tool industry. In 2010, 12207 CNC forging machine tools were produced. The growth rate was 8.1% according to the statistics of the product data reported by the domestic 40 forging machinery. The number of numerical control products accounted for 6% of the total products, and the output value accounted for 40% of the total product. The number of numerical control products is increasing slowly.
In 2010, the export of the forging machine tool was 569 million dollars, up 24.48% from the same year, the export of CNC forging machine tool was 110 million US dollars, up 34.4%, and the import of the forging machine tool was 1 billion 900 million US dollars, up 42.4% from the same year, and the import of CNC machine tool was 1 billion 10 million US dollars, up 43% compared to the same period.
The number of all kinds of forging machinery production enterprises has increased rapidly. By the year of 2010, the annual output value of the enterprises is more than 5 million yuan, and more than 460 enterprises. There are about 100 thousand employees in the whole industry.
3. sheet metal machine
Sheet metal machinery can be divided into coil pretreatment equipment and processing equipment. The coil pretreatment equipment mainly refers to the open coil leveling and longitudinal shear winding production line, the open coil leveling horizontal shear sheet stacking production line. In recent years, because of the rapid increase in the use of coils in China, the specifications, varieties and quantities of the pretreatment equipment have increased rapidly, and the technical level has been rapidly improved, which basically meet the demand of the domestic market. In addition to end user procurement, the equipment supplies a large number of distribution centers. The thickness of the sheet can be processed by 03mm~25mm.
Mechanical press, hydraulic press, high speed press, rolling machine, CNC turret punch, shearing machine, roll forming production line have made obvious progress in processing precision, reliability, technical index, energy saving and agreeable, and the new product development ability and market competitiveness are greatly improved. In particular, thin plate processing equipment, many enterprises can provide compound processing machine, processing unit, automatic production line and flexible production line, large scale sheet metal three large parts CNC turret punch press, bending machine, shear plate machine performance reached the international advanced level.
The construction of oil pipeline, large engineering machinery, shipbuilding and vehicle manufacturing in China have promoted the advent of a large number of new, special and large forging equipment with international advanced levels, such as large numerical control shear equipment, profile bending equipment, heavy roll board machine, ship board press, large multi position press and so on. The new technology and equipment of sheet metal processing and laser cutting machine have been growing rapidly. In 2010, more than 1000 high-power laser cutting machines with over kilowatt production in China became the highlight of the rapid growth of sheet metal machinery in China. The structure, auxiliary equipment, workpiece and application of the laser cutting machine are the same as that of the CNC punching cutting machine. At least, it is reasonable at least to manage the forging equipment at present.
At present, Ji'nan of Shandong and Yangzhou of Jiangsu have become the agglomeration areas of China's sheet metal machinery industry. The overall view of its innovation ability and product technology level is in the lead in China, and has good prospects for development.
4. forging machinery
In recent years, the forging equipment with special functions of special structure, which is guided by new technology, has been constantly appearing, such as isothermal forging equipment, hot stamping equipment, electromagnetic forming machine, special material forging equipment and so on.
The rapid development of power generation equipment, large aircraft, ships, military aircraft, space and vehicles has greatly promoted the progress of heavy forging and extrusion equipment in our country. China has become the country with the largest and largest heavy duty forging hydraulic press and heavy die forging hydraulic press in the world. Moreover, the tonnage of the die forging hydraulic press will be renewed again.
Represented by the programmable hydraulic hammer, the forging hammer equipment has made great progress in the development direction of energy saving, environmental protection and numerical control. In the same way, the screw press adopts numerical control technology and combines the advanced switched reluctance motor technology to become an electric spiral press which can strike the energy and the position of the lower dead point. Qingdao green forging and Forging Machinery Co., Ltd. is manufacturing 80000kN electric screw press for domestic customers.
China has been able to manufacture a heavy rolling ring machine with automatic laser control for rolling process, and can roll 10m rings. The forging equipment of hot die forging press, flat forging machine, automatic cold heading machine, roll forging machine, rolling mill and other forging equipment adopt new control technology, testing technology, specification expansion and product technical level greatly. The user has a lot of room for equipment selection.
5. other
At present, the CNC pipe bending machine, riveting machine, spinning machine, rotary forging machine, radial forging machine and other small door products also have more manufacturing enterprises, the product level can also reach the advanced level of foreign countries. In the past, there were only straightening and cutting machines and bending machines used for building construction sites. In 2006, a complete set of steel processing equipment was developed in China. It is used for the factory production of steel building components and can be used to distribute steel bars for construction sites.
