The Linxi bearing industry experienced four stages of development, manufacturing and assembly, large-scale production, and branded manufacturing. It successfully achieved two shifts from the production of low-speed carbon steel bearings to the production of high-speed precision bearings; Occupy the transition from low-end markets such as domestic and agricultural bearings to the general industrial market, and the internal driving force for these changes is the implementation of the genetic restructuring of the bearing industry in Linxi.

Gene recombination 1: Linxi Manufacturing began in the Lin Xixian bearing industry in the 1970s. Initially, it was home-based small workshops. The industrial genes of that time were extensive, disorderly, and disordered. In order to speed up the upgrading of the bearing industry, Linxi actively guided the entire industry to carry out genetic reorganization and create its own industrial genes. First of all, rely on scientific and technological innovation to create Linxi to make genes. The proposal made by Linxi to manufacture genes originated from the benchmarking with foreign advanced products. According to a statistics from the former Ministry of Railways, some of China's truck-specific bearings rely on imports, which is a far cry from the world's advanced level, and Guo Shoujing, the originator of the world's bearings, is a Xingtai man. To this end, Linxi County has accelerated the pace of independent innovation by local bearing companies, increased the technological content and competitiveness of products, and achieved new births in the bearing industry. Up to now, the county has invested more than 2.5 billion yuan in technical reforms, and injected 1.2 million yuan to establish a provincial rolling bearing inspection station, in the supervision, quality, measurement, standardization, special equipment and other related businesses, for the company to establish product quality files.

In the interview with Linxi, the reporter learned that this year, Hengtai Ruixin Bearing Co., Ltd. cooperated with Tsinghua University, and had a lot of brains in bearing design, fine grinding and other links. They jointly developed special bearings for trains and applied for national patents. The product can increase the load of a single truck wagon to 80 tons - 100 tons, and has the characteristics of long service life, strong stability, etc., and can completely replace similar imported products. At present, Linxi has targeted the research and manufacturing fields of higher-standard passenger cars and high-speed rail bearings, and continues to hold the core technology of the bearing industry firmly in their hands. According to statistics, the bearing production enterprise of the county declared 18 national patents last year, and achieved 325 types of technological innovations. Bearing products relying on imports will soon be replaced by Linxi Manufacturing.

Gene recombination II: Equipment consciously upgraded The second industrial gene that created Linxi Bearing was the conscious upgrade of equipment. Linxi County Party Committee Secretary Zhang Xijun introduced that, of the annual sales revenue of Linxi Bearing, more than 25% were sales revenue of foreign products in Linxi. The reason that this kind of strong industry is not strong is the relative lag in the production of bearings, and the reason for the relative lag in bearing production is the backwardness of technical equipment. Before the company's equipment can not meet the production requirements before considering replacement, is completely a spontaneous state. Nowadays, everyone regards equipment upgrade as a weapon for market competition. It is already a state of self-consciousness. Lin Bingxiang, deputy director of the Bureau of Industry and Commerce of Linxi County, said.

The reporter felt this conscious state when interviewed by Hebei Baoxin Bearing Manufacturing Company. Qi Xiuhui, general manager assistant of the company, pointed to a lathe and told reporters: This is a semi-automatic machine tool, which is already more advanced than the average lathe, but we still eliminated it. Why? Processing a single part requires 7 machines and 7 processes. Now with the introduction of automated inline equipment, two machine tools will be able to complete the above process with higher accuracy. He picks up a semi-finished part from the processing table. This is the 7518 bearing used by the car. The original production line of 10 workers can only produce 2,000 products per day, and now the two workers can produce 5,000 sets of production efficiency. A lot more.

In the past, it was to fight resources and fight for low costs. Now it is fighting for innovation and high value-added. This will depend on the introduction of advanced and applicable technologies and equipment to extend the industrial chain. Qi Xiuhui said. It is understood that since last year, the 386 large-scale bearing enterprises in Linxi County have updated 1082 sets of production equipment, and over 85% of the scale bearing enterprises have achieved automation through equipment upgrades.

Zhang Xijun told reporters that from the spontaneous upgrade of equipment to consciously upgrading, it reflects the change in the value orientation of the entire bearing industry. That is to say, Linxi Bearing is moving away from the primary and low-end conditions to the general and high-end transition.

Gene recombination three: Green technology reform A few days ago, the reporter saw in the workshop of Hengtai Ruixin Bearing Co., Ltd. that a fully automatic cooling water circulation pump was constantly running, and the grinding liquid that flowed out of the workshop was precipitated and filtered, and then it was recycled through the pipeline. Inflow into the production workshop is used again, and the precipitated solid grinding slag and iron pin can also be directly recycled by the steel mill for secondary smelting. The company's responsible person Li Weifu introduced that the company has invested more than 20 million yuan, the original hydraulic machine for green technology, the establishment of a large circulating fluid grinding system, to achieve zero discharge of the grinding fluid, zero pollution, water and electricity savings reached 90%, respectively More than 70%.

The reporter learned that the waste grinding fluid discharged from the bearing processing stage is the largest source of pollution to the external environment. In recent years, the scale bearing enterprises in Linxi County have resorted to equipment renewal and adopted the centralized circulation liquid supply mode, which has solved this problem.

Previously, the bearings were cleaned with kerosene. Last year, we invested more than RMB 1 million in new bearing cleaning lines and switched to professional cleaning fluids. In Runhe Bearing Co., Ltd., Chief Engineer Yang Guang picked up bright bearings and told reporters that the price per ton of cleaning fluid is 20% cheaper than that of kerosene. Calculating at 50 tons per year, it can save nearly 400,000 yuan annually. At the same time, the cleaning liquid is odorless, non-polluting, and the waste liquid can be recycled.

In order to reduce energy consumption, the county actively implemented technological transformation. Since last year, the county's 386 bearing enterprises above designated size have independently invested 1.085 billion yuan in technical reforms and completed 21 technological transformation projects. Among them, 15 new bearing cleaning production lines, driven by technological changes, the annual energy saving and consumption reduction of bearing enterprises was 8.57 percentage points, and the income increased by more than 3 million yuan.
