Domestic high-end bearing development needs multiple channels in parallel

In the era of economic globalization, China's auto, aerospace, and medical industries are also booming. This virtually provides a broad development platform for the domestic machinery foundry industry, while China's hardware bearing industry also has a steady upward trend. In recent years, the production scale of bearings in our country has expanded rapidly. The number of bearing enterprises has approached 2,000, of which nearly half belong to large enterprises and sales revenue exceeds 5 million.

At present, China's hardware bearings have constituted a large economic scale, but with the development of the market, users have increasingly higher requirements on the accuracy, performance, and types of bearing products. This has also evolved into a market demand for high-grade bearings. increased. This also requires China's bearing companies to actively develop high-end products that meet the market demand, in order to reach domestic demand through independent innovation and brand building, and drive the basic machinery foundry industry to the international field.

Not only that, under the guidance of the "Twelfth Five-Year Plan", China's high-end bearing casting industry has formulated an industry development plan. Formulated guidelines for the development of the domestic mold industry with projects and exporting two carriages. It is believed that under the drive of development in various fields such as rail transit, medical equipment, new energy, aerospace, and automotive lightweight, the level of China's bearing foundry industry has been significantly improved.

The mechanical casting industry has made steady progress in the traditional market and is actively exploring new channels. Today, China's mechanical casting industry is moving in the direction of high product quality and lowering manufacturing costs, and strives to bring it to or near the international advanced level. It is expected that with the support of the policy, by 2015, the sales volume of the high-end bearing foundry industry will reach 222 billion yuan.

The hydraulic machine mostly uses a liquid as a working medium, and a machine made according to the Pascal principle for transferring energy to realize various processes. The hydraulic machine is generally composed of three parts: the machine (main unit), the power system and the hydraulic control system. Hydraulic machines are classified into valve hydraulic machines, liquid hydraulic machines, and engineering hydraulic machines.

Different designers from different companies have different design concepts, resulting in different quality and basic differences.

The hydraulic machine is divided into four columns: single column type (C type), horizontal type, vertical frame, universal hydraulic machine, etc. according to the structure.
Hydraulic presses are mainly divided into metal forming, bending, stretching, punching, powder (metal, non-metal) forming, press fitting, and extrusion.
