A Road to Prosperity: A Record of Technical Innovation Work of Xuanhua Construction Machinery Group Co., Ltd.
1 Revolving around improving quality Innovation 1 is the life of an enterprise and a magic weapon for companies to occupy the market.
The bulldozer loader and other products produced by Xuangong are used as the mechanical construction equipment to perform ten stone operations instead of manual work. The user's most important quality requirement is to use the blade with high efficiency and fewer faults. In order to meet the quality requirements of users, Xuangong directly focuses on technological innovation to improve product quality. Through the adoption of various advanced technologies, the quality of products has been continuously improved. The Ding 1401 crawler bulldozer is the leading product of Xuangong, and it has entered the ranks of international mechanical drive bulldozers as a result of its timely replacement. In order to continuously improve its quality and enhance its competitiveness, Xuangong focused its attention on improving the level of technological equipment of enterprises. In the past, due to the backwardness of the technical equipment of Ding, when the hole of the rear axle box of the bulldozer was processed, the coaxiality could not be guaranteed, and the unqualified or waste products were often caused. In order to solve this quality problem, the company has spared no expense and has purchased two horizontal machining centers with international advanced level from Japan, dedicated to processing the rear axle box, thus fundamentally solving the problem of coaxiality of the rear axle box holes. To ensure the processing quality of the rear axle box; In order to continuously improve the manufacturing technology and process level of the product and ensure the processing quality of parts and components, it has also purchased the Japan-made photoelectric tracking cutting machine Italy's CNC profiling milling Swiss automatic production Arc welding machines Austrian welding robots American heat treatment furnaces. Highly sophisticated equipment; In addition, it also produced a multi-headed CNC flame cutting machine, using CNC technology to transform more than 40 old equipment, enabling it to achieve simple numerical control, raising the processing precision. The company also successively built the largest fully enclosed air-conditioning assembly plant in the nation's push-up machine industry, realized assembly line assembly operations, established a new steel pretreatment production line and resin sand molding production line, and fully implemented computer-aided design. The comprehensive improvement of the level of production technology, equipment and technology has enabled the production process of the company's products to go from blanking and forging to heat treatment, from the welding of riveting machines to the assembly of components and complete machines, all based on a reliable technical foundation, and quality has been achieved. A tangible guarantee.
It is a mountain stone that can attack jade. Adopting international advanced level push-on technology to continuously improve and improve the overall performance of our products is a way for Xuangong to open up new technological innovations that focus on improving product quality. For example, replacing the original balance beam of the old product with a balance beam with a buffer structure with the introduction of a bulldozer greatly improves the condition of the impact load of the entire machine; with the introduction of a push-pull machine, a device replaces the roll device of the old product, significantly improving The production performance of the old product; the simple structure of the introduction of the bulldozer walking buffer device replaces the complex structure of the old product, extending the life of the walking buffer device. In addition, the imported bulldozer manufacturing technology was used to process gears with a heavy load of people's displacement coefficients, which increased the strength of the final transmission gear of old products, and so on. All these have achieved good results in improving the reliability and service life of the Ding 1401 crawler pusher of the old product. Due to the continuous improvement of quality, the 1401 bulldozer has continuously maintained the industry's only other products and won the title of high-quality products. It has been repeatedly rated as the National Customer Satisfaction Product and China Machinery Industry Famous Brand Products.
2Innovation in product development In accordance with the general principles of development and production of what is required by the user and the development trend of international construction machinery products, the company has gradually formed a series of similar products in practice, and diversified products with different standards and new standards with high standard of development. Development strategy.
The serialization of similar products means that in the vertical direction, a series of 140150165220330 products have been formed on the basis of the horsepower that is pushed onto the machine; this means that the horsepower and the basic models remain unchanged, but it is to satisfy the users. Cheng Machinery, 2000 quality management marketing machine as the company's leading products to meet the needs of most users of the construction, but some users of the mountain operating conditions, put forward some new special requirements, the company according to the various companies in various industries push Ten machine tracks were changed to angular shape and widened in size to produce a low specific pressure bulldozer for Ding 8140 Wetland adapted to the soft earthwork operation in the marshland; by changing the shape of the bulldozer's man shovel, the cattle. Output Ding 140 push-pullers adapted to port clearance operations and push-pullers adapted to coal mining operations; through the addition of a winch device behind the pusher, a bulldozer adapted to the logging and push-up operation of tropical forests was produced. Winch and so on. Among them, Ding 5140 wetland crawler bulldozer has undergone several improvements and improvements, becoming the second leading product of the Dinggong second only to the Ding 1401 crawler bulldozer.
The diversification of different types of products refers to the development of bulldozers as the main business, and actively develops other products with large consumer demand and promising market prospects. In the early 1990s, the company successively developed the ZL60FZL50ZL30E model tire loader, and quickly formed a batch production capacity and put it on the market. In addition, the company also actively marched into the field of road rollers and developed a 88-vibration vibratory roller in cooperation with Xi'an Highway College, filling the gap in the 8-ton combined roller of China.
The development of a high level of standardization means that there is a gap between the current technological development capability and manufacturing level of the enterprise and the developed countries such as the United States and Japan, and it is impossible to immediately eliminate the gap and implement the leapfrogging stage of technological development, closely following the international leading enterprises. Strategy. In the United States Caterpillar cattle. Based on the digestion and absorption of similar products produced by the company, the company proceeded from the actual conditions of the company and boldly innovated. In 1993, it developed China's first 8,7220 hp high-powered bulldozer. The product changed the design method and structure of traditional bulldozers, abandoned the traditional bulldozer belts arranged on the line model, using drive wheels off the walking frame, high placed in the final drive of the central transmission steering clutch on the coaxial line, so that the track New technologies such as angular enveloping and modular assembly have the irreplaceable superior performance of conventional bulldozers. The product was awarded the Science and Technology Progress Award from the Ministry of Machinery and was listed as a national new product. In 1995, the company also focused on the development of the 8,8330-hp high-powered bulldozer. Due to the use of computer-aided design, the development speed was artificially accelerated, and the first prototype was successfully implemented in less than a year. In the month of 1999, at the Beijing International Construction Machinery Products Exhibition and Technology Exchange Conference, the prototype received much attention and praise from relevant experts and users.
Since the reform and opening up, according to the market demand, Xuangong has cumulatively developed 3 new products. The speed of developing new products has been developed from the past 45 years and has been increased to an average of 2 years and 3 developments, which is 6 times before the reform and opening up. many.
3 In order to reduce consumption, the important content of innovative market competition is price competition. To make products have price advantages, it is necessary to reduce various consumptions and reduce manufacturing costs. To this end, Xuangong also unremittingly vigorously carried out technological innovation activities that focused on energy conservation and raw material conservation.
First of all, the company has focused its work on energy conservation. In the past, I had to save energy to save energy. In addition to strengthening energy management, we have invested more than RMB 4.5 million in the company’s major energy-consuming equipment and facilities. Various forms of technological transformation. The main item 0 has invested RMB 250,000 in 1991 to transform 4 industrial boilers and realized the automatic monitoring and regulation of the microcomputer. The annual coal saving is over 700 tons and the electricity saving is 150,000 kilowatt-hours. In 1993, the investment was over 230,000 yuan. The air compressor station was reconstructed to achieve variable frequency speed control and joint control, with a power saving rate of over 30. In the same year, it also invested 40,000 yuan to build a self-provided water supply system, and afterwards invested 500,000 yuan in successive major water consumption processes. The water-saving technological transformation was carried out. The annual water saving was up to 750,000 tons and the electricity saving was 100,000 kilowatt-hours. As a result, the company could spend less of the total cost of utilities and water resources of RMB 360,000 per year.
Since 1994, it has successively invested 800,000 yuan, will use more than 30 years of steam forging hammer into a hammer, energy-saving rate of 95 or more, annual energy savings of more than 600,000 yuan. In 1997, the company invested 540,000 yuan to transform the hot gas furnaces that have been used for many years to use city stairs.
As the saying goes, saving is earned. Through the implementation of energy-saving technological transformation, the total energy consumption of the company has not substantially increased since 1991 when the output of products and the total industrial output value have increased year by year. It is estimated that by the end of the 9th period, with the improvement of major power-consumption and water-consuming facilities, the total energy consumption of the entire company will also decrease by a certain amount.
In terms of saving raw materials, the company actively adopts advanced and reasonable technologies to minimize the consumption of raw materials. In terms of value engineering principles, from optimizing the product design structure, according to the principles of economically favorable technology, scientifically determine the product's structural shape and size, and prioritize the use of low-cost new materials, replacing high-cost old materials to reduce consumption. cost. Such as the quality of the technical center. The bridge box rear cover water tank replaced bulldozer blade materials, etc., to save more than 100 million. On the other hand, from the optimization of process improvement methods and the use of domestic tool cutting tools instead of imported knife blade and other people in order to achieve savings. The following material plants adopt the method of using kit materials to make full use of the corner materials, saving more than 70 tons of steel annually; the steel casting factory adopts the multi-casting method of the box, which not only improves the work efficiency, but also reduces the The sand-steel ratio saves many million yuan each year. The production technology department saves more than 100,000 yuan a year by using domestic tools instead of the horizontal cutters used in the center.
In a word, Xuanhua Construction Machinery Group Co., Ltd. actively develops technological innovation by focusing on improving product quality and developing new products, saving energy and reducing consumption, and enables companies to grow from small to large and from weak to strong. The development momentum is growing.
Looking back at the path we have travelled, we deeply feel that in the fierce competition of the socialist market economy, if a company wants to survive and develop, it must continue to innovate breakthroughs in technology, and whoever seizes the technological system, Anyone will seize the initiative of the market and will be able to win the water in the ocean of market economy.

What adaptability improvements are needed and what new products are required for the large-scale development of the western region? Leaders of the Xugong Group led the team to investigate and visit the cities of Xi’an, Shaanxi Province, Urumqi, Xinjiang, Xining, Qinghai Province, Qinghai Province, Gansu Province, and Lanzhou City, and took the form of opening talks. , Fully communicated with the scientific research institutions and the leaders of major construction units of the railway bureaus of Luqiao City Road and Bridge Bureau mentioned above and reached the expected 0.
1 At present, the policies and conditions for the development of the western region can feel the positive atmosphere of the western development boom. Domestic research institutions of construction machinery manufacturers have started investigations and have taken actions such as Liugong. Xiamen Shangchaishan pushing has already started investigations or plans to start investigations, and there are also initiatives in market development. The advance marketing research activities of foreign-funded enterprises and joint ventures have also begun. For example, almost all of the excavator joint ventures in the country have sent staff to visit the northwest. The local people are also talking about how to make good use of this opportunity for development and embrace a bright future.
The key points for the construction of various regions in the northwest are different. The goal is to build Xi’an into a cultural and transportation center, Lanzhou as a financial center, and Urumqi as a border trade center.
The two major ideas developed in Shaanxi are the implementation of the Shan Xiumei project, which is mainly a systematic project for the treatment of sediments; it is a railway network that has built two horizontal and vertical junctions in Shaanxi in a few years time, and has been increased on the basis of the main skeleton of the “M†shaped roads. Density, increase in rank, and the formation of a radial, graded highway network centering on Xi'an as the main 9 lines of the 9-nation highway.
The development of Xinjiang will mainly focus on rich underground resources, especially the development of oil and natural gas. Xinjiang's highway construction will invest 15.7 billion yuan during the tenth period. This year, the company has invested RMB 4.7 billion in advance, and it has completed the goal of highways in the townships as soon as possible. There are still five townships failing to pass this year.
Qinghai will protect the ecological environment, strengthen ecological and environmental protection at the source of rivers, and vigorously develop the characteristic economy of the pillars of non-ferrous metal hydropower resources in oil and gas and salt chemical industry. For this purpose, the expansion of the Tibet Railway and reconstruction of the provincial roads of the national highways will also be implemented in the near future. Aviation networks in the province will be established to accelerate infrastructure construction such as water conservancy and town development.
