The history of outsourcing of Valin Auto Axle ended in 2007, and the establishment of the Axle Project Team marked that Hualing’s road to independent innovation has risen to a new level. Chairman Liu Hanru once said on the Hualing Axle Project that Chinese companies need control over the industrial value chain, and that companies that value the value of security are ultimately subject to human control. They lack the right to speak in controlling the general trend of industrial development. In the long run, Valin car to develop, we must extend the value chain, cut into parts is the choice to do what best interpretation of the axle Valin development strategy.

When talking about the development of Hualing Axle, Lu Jun, Minister of Technology of Hualing Axle Co., Ltd. mentioned that prior to the independent R&D of Hualing Axle, he was in charge of material procurement and he really realized that the pain caused by being controlled by others was in the blowout market after heavy snowfall in early 2008. The main reason why the customer could not mention the car was that the axle was not yet in place. Another reason that Hualing independently researches and develops axles is that the quality problems of outsourcing bridges are many, which is a fatal injury to the development of the quality of Hualing Auto. Valin's heart has accelerated the development of the axles. From the initial axle project team to the current Foma axle company, the development of Valin has succeeded in getting rid of the bitterness.

Technological innovation

In recent years, the pace of development of Hualing Axle has followed the market situation, and it has continuously introduced new products. Product R&D and production work are in full swing. According to Lu Jun, the Director of the Technical Department of Axle Bridge, a total of 13 varieties of new axle products were developed in 2011. A total of 6,1995 kinds of axles were produced, including 27,273 front axles and 34,722 drive axles, which effectively protected the production of Valin. The products that can satisfy the market are truly good products. Axle Technology Department developed a new lightweight HLD4/E4 series single-stage reduction bridge (460 drive axle) to meet the company's product strategy, including 4.30, 4.10, and 3.73 speed ratios. It has entered the mass production phase and the development of the 460 bridge. It laid a solid foundation for the lightweighting of Hualing. It is understood that this year, Valin's main trolley-type lightweight Xingkaima is equipped with 460 bridges.

For the Steyr and Mercedes-Benz technologies that lead the world of heavy-duty truck technology, the axle technology department also developed a new drive axle last year. At present, the mining trapezoidal suspension series HLF1/G1 drive axle (Steyr Drive axle) has been developed and put into production in batches; the development of the widened bearing of the HLF2/G2 series drive axle (Benz drive axle) has been completed and has been mass produced. In response to market feedback, in order to improve the bearing capacity of the product, the axle technology department developed HLD series disc brake front axle (5.5-ton front axle) and has completed the road test. Lu Jun told the author that the axle technology department had obtained 29 national patents in 2011, stably and steadily advancing the patent work; successfully declared 7.5-ton steering front axle, HLF1/G1 cast steel wheel side deceleration drive axle, two provincial high-tech products . In the product information platform construction, the axle technology department has implemented the PTC IntraLink data management project. This project plays an important role in preventing data loss and improving the standardized management of enterprise product design.

This year, the work of the axle technology department is to complete the R&D, test work and mass production of the front and rear axles of the dump trucks at the Valin Mine, and to accelerate the construction of an information platform to improve the TCPLM data management project. Then it completed the development work of the 9-ton series front axle and the Steyr front axle series of Valin, and achieved mass production, completed the development trials of the front and rear axles of the disc brakes, and promoted 1 million kilometers of maintenance-free hub bearings.

Strict control of quality

As for the quality of axles, Yang Xuanxin, the director of the company's quality management department, proposed that it is necessary to strictly control the axle parts and eliminate the entry of unqualified products. The quality of the axle components is a key part of the axle quality control. To this end, the axle quality department must carry out systematic inspections on the parts and components provided by the supplier, and can enter the factory only after passing the inspection; And to measure its shape and size, to ensure that the size of the parts meet the requirements of technical drawings; the Ministry of Quality will irregularly send parts and components to third-party testing agencies. Once unqualified products are found, they will report in a timely manner and fill in the non-conforming items. , And according to the warranty agreement to the supplier to make quality penalties.

Second, unqualified products in axle assembly inspections are not put into production, are not forwarded, and are not released. During this period, line inspections, no-load test stand inspections, paint inspections, factory inspections, etc. will be carried out. It is worth mentioning that the test of the empty test stand is a test procedure for testing the overall performance of the finished product bridge, including abnormal noise, Oil temperature, noise, differential speed and other testing links are in time to be reworked and will not be released. Yang Xuanxin mentioned that the running time of the running platform has been increased to 3 minutes, and the total rotation time is 6 minutes, further strengthening the axle quality control and upgrading. Axle quality. In addition to rigorous testing and inspection of products, the quality department also regularly conducts training and assessment of inspectors, and enhances the quality of the axle products by improving the quality and skill level of the quality inspection team. Then collect feedback on quality information and quickly provide quality rectification services. Yang Xuanxin said: "For the factory-built axles, we follow-up in real time and timely analyze the problems of Hualing's final assembly and after-sales feedback and come up with solutions."

According to Yang Xuanxin introduction, this year's axle quality management will implement the ISO/TS16949 quality management system, from product planning, design and development, manufacturing process design, production process confirmation, analysis and control of non-conforming products, corrective measures, and preventive measures. Process control. ISO/TS16949 is the latest and recognized quality management system in the global automotive industry. It implements and implements the ISO/TS16949 quality management system. While improving product quality and the market competitiveness of Valin Automotive, it also reduces multiple audit certifications. It lays a solid foundation for the internationalization of Valin Auto.

Hualing Axle has become a new bright spot for upgrading the quality of Hualing.
