Forging machinery industry gathered casting machine image upgrade

The China Machine Tool Industry Association Foundry Machinery and Forging Machinery held the 2011 Annual Meeting and the Fifth Session of the Fifth Session of the Board of Directors. Nearly 100 representatives gathered in the Jinan Casting and Forging Institute, summed up the "Eleventh Five-Year" development gains and losses and discuss the decline in the industry growth. The countermeasures. Liu Jiaxu, chairman of the two branches and chairman and general manager of Jinan Casting and Forging Co., Ltd., made a systematic summary of the achievements made by the industry during the “Eleventh Five-Year Plan”.

Industrial Agglomerations have their own characteristics. Liu Jiaxu said that during the “11th Five-Year Plan” period, China’s forging and pressing machinery industry has developed rapidly. Forging and other equal-volume forming equipment and sheet metal processing equipment have developed in parallel. It has a full range of specifications, rapid number growth, and new products and technologies. With the application and other views, the overall technical level and numerical control rate of the product continued to increase, and a large number of exports were realized, which met the needs of China's economic development.

According to the statistics and analysis of the club, in 2010, the total output value of China's forging machinery industry was about 40 billion yuan, a year-on-year increase of over 42%, a record high. According to statistics reported by the 40 forging machinery companies in the branch, numerical control products account for 6% of all products, and output value accounts for 40% of the total output value. The number of CNC products has grown slowly. In 2010, the forging machinery industry produced more than 200,000 forging presses, an increase of 18.0% year-on-year.

In 2010, China exported 569 million US dollars worth of forging machine tools, an increase of 24.48% year-on-year; CNC forging machine tools exports 110 million US dollars, an increase of 34.4%; forging machine tools imported 1,900 million US dollars, an increase of 42.4%; among them, CNC forging machine tools imported 1,010 million US dollars , an increase of 43.0%.

During the “Eleventh Five-Year Plan” period, the scale of enterprises in China's forging and rolling machinery industry has been continuously expanding, and many companies have emerged in the market competition. This has also formed some forging industry clusters. For example, Jiangsu Province has a prominent position in the forging and pressing machinery industry in China and its regional output accounts for 1/3 of the country's total. Mainly distributed in Yangzhou, Nantong and Wuxi.

The size of forging enterprises in Jiangsu Province is about 1,000, and the total output value is estimated to exceed 10 billion yuan (in 2010, only 12 key contact enterprises in Jiangsu had sales of 7 billion yuan). Among them, Jiangsu Yangli alone contributed 2 billion yuan.

Another example is Bowang Town, Maanshan City, Anhui Province. It is estimated that there are 200 enterprises in the forging and pressing industries, mainly for sheet metal cutting, with a total size of more than 3 billion yuan. The largest company's annual production value has reached more than 100 million yuan.

Jinan and its surrounding areas have also formed a gathering area for forging products, represented by Jinan No. 2 Machine Tool Group and Jinan Casting & Forging Co., Ltd., with a total scale of approximately RMB 5 billion. Among them, Jinan No. 2 Machine Tool Group ranks first in the scale of forging and sub-branches with 2.4 billion yuan.

In addition, Qingdao and surrounding areas have more than 2 billion yuan in friction presses and sheet metal processing equipment clusters; precision machinery presses and high-speed presses in Ningbo, Zhejiang Province have already formed scale and characteristics.

In terms of sheet metal processing equipment, due to the surge in coil usage in China, coil pretreatment equipment such as uncoiled straightening and slitting rolling production lines and uncoiled horizontal and horizontal sheared sheet metal palletizing production lines have grown in terms of specifications, varieties, and quantities. Rapidly, the level of technology has rapidly increased to basically meet the needs of the domestic market. In addition to end-user purchases, these equipments supply a large number of plate distribution centers. The plate thickness can be processed from 0.3mm to 25mm.

Mechanical presses, hydraulic presses, high-speed presses, coiling presses, numerical control turret punch presses, shear folding machine tools, roll bending forming lines, and other sheet metal processing equipment in terms of processing accuracy, reliability, technical specifications, energy saving, emission reduction, human friendliness, etc. All have made significant progress, and new product development capabilities and market competitiveness have greatly increased.

In particular, thin sheet processing equipment, many companies can provide composite processing machines, processing units, automated production lines and flexible production lines; a large amount of sheet metal three major parts - CNC turret punch press, bending machine, shears, its performance Both reached the international advanced level. In 2010, the annual sales volume of CNC turret punch press exceeded 2,000 units, an annual increase of more than 20%.

China's oil pipeline construction, large-scale construction machinery, shipbuilding, and vehicle manufacturing have promoted a large number of large-scale CNC shearing equipment, bending equipment, heavy-duty coiling machines, shipboard presses, large multi-station presses, etc. The advent of advanced, new, special, and large forging presses.

The new technology of sheet metal processing equipment - CNC laser Cutting Machine growth is rapid, China's slightly larger sheet metal machinery manufacturers have developed a laser cutting machine. In 2010, China produced over 1,000 kilowatts of high-power laser cutting machines and became a bright spot for the rapid growth of sheet metal machinery in China. The main structure of the laser cutting machine, auxiliary equipment, machining workpieces, and the use of the occasion are the same as the CNC punching and cutting machine. Therefore, the laser cutting machine is classified into forging equipment to manage it.

At present, Jinan, Shandong, Yangzhou, Jiangsu and other places have become China's sheet metal machinery industry gathering area. As a whole, innovation ability and product technology level are leading domestically and have a good development prospect.

Since the “Eleventh Five-Year Plan”, forging equipment with special structures and special functions, which are guided by new processes and meet the requirements of new processes, have also emerged. For example, isothermal forging equipment, hot stamping equipment, electromagnetic forming machines, special materials forging equipment, etc.

The rapid development of power generation equipment, large aircraft, ships, military aircraft, aerospace, and vehicles has greatly promoted the progress of large-heavy forging and extrusion equipment, making China the largest tonnage of heavy-duty forging hydraulic presses and heavy-duty forging hydraulic presses with the largest tonnage. s country. Moreover, the tonnage of the forging hydraulic press will continue to be refreshed.

Taking the program-controlled hydraulic hammer as the representative, great progress has been made in the development direction of energy saving, environmental protection, and numerical control for the forging hammer equipment. In the same way, the screw press adopts numerical control technology combined with advanced switched reluctance motor technology to become an electric screw press that can accurately control the energy and position of the bottom dead point. At the same time, China has been able to manufacture a heavy-duty ring mill that automatically measures the rolling process of the laser and can roll 10m diameter rings. In addition, CNC pipe bending machines, riveting machines, spinning machines, pendulum mills, radial forging machines, and other small door products have also been developed by a large number of enterprises, and their product levels have reached advanced foreign standards.

The effect of industrial upgrading has begun to appear. For the foundry machinery industry, Liu Jiaxu concluded that during the "11th Five-Year Plan" period, the industry maintained a momentum of rapid development, and technological progress made the foundry machinery industry change its low-end image of "stupidity and darkness."

According to statistics from the association, although the total industrial output value of China's foundry machinery industry hit another record high in 2010, the numerical control rate of foundry machinery products is still relatively small. From the point of view of export, the annual export value of the foundry machinery industry is about 100 million U.S. dollars, and the export volume is 1,500 units, of which the numerical control products account for less than 20%. From the perspective of China's entire machine tool industry, the export of foundry machinery accounts for a very small proportion, and the overall technical level of the industry is a long way to go. According to the import situation, the annual import value of the foundry machinery industry is more than 200 million U.S. dollars and the import volume is about 500 units. During the "Eleventh Five-Year Plan" period, the import and export of the foundry machinery industry showed an unstable trend. There was a situation where imports fell sharply and exports fell sharply for three consecutive years. Foundry machinery industry is affected by the national policy and industry situation.

During the “Eleventh Five-Year Plan” period, enterprises in the foundry machinery industry developed rapidly, traditional competitive enterprises such as the Jinan Casting and Forging Company maintained the leading position, and Baodingville, Tianjin Hunter and other foundry companies made remarkable progress and their development momentum was strong. Take Baodingville as an example. During the “Eleventh Five-Year Plan” period, it has become the fastest-growing five-year period. Its output value has grown from around RMB 200 million at the beginning to the present RMB 700 million.

Relevant data show that in 2010 China's total output of castings reached 39.6 million tons, and the output value exceeded 400 billion yuan. The output of castings ranks first in the world for 11 consecutive years. At present, most castings have been independently manufactured, and only a few high-end castings need to be imported. At the same time, the scrap rate of domestic castings has decreased significantly. Some key indicators such as dimensional accuracy and surface roughness of castings have reached the international advanced level, and the technical grades of export castings have also been greatly improved. Since the “Eleventh Five-Year Plan” period, there have been a number of foundry companies in China that are close to and have reached world advanced level in scale and technology, and have achieved obvious advantages in international competition.

The domestically produced castings can achieve the above-mentioned gratifying results, which can not be separated from the continuous improvement of the level of China's foundry machinery and the continuous increase in market share as a support and guarantee. During the "Eleventh Five-Year Plan" period, China's foundry machinery industry enterprises have continuously developed cost-effective casting machines through technology introduction, digestion and absorption, and independent innovation, which have basically met the needs of domestic mid-to-high-end casting manufacturers. In this process, the professional level of the company has been continuously improved, which has led to an increase in the level of product technology and an increase in the rate of product numerical control. The superiority of specialized production is further reflected. At the same time, the concept of “green casting” such as energy saving and emission reduction, safety and environmental protection has been increasingly strengthened in the foundry industry.

Since the “Eleventh Five-Year Plan”, through the unremitting efforts of industry enterprises, the level of China's foundry machinery has greatly improved, and many successively developed casting machinery products have been developed, which has laid a good foundation for the further development of China's foundry machinery industry. basis. Such as large-scale resin sand casting production equipment, has basically been able to meet the needs of the domestic market, changed the situation in the past mainly dependent on imports; has been able to produce a high level of automatic casting production line, to partially replace the import level, partially changed Car engine block, cylinder head and other casting blanks need to be imported; in addition, high-level automatic core machine, automatic casting machine, automatic sand processing machine, large automatic die casting machine and casting equipment such as precision casting equipment, domestic casting machine manufacturers Basically, it can be manufactured.
