Liugong Loader Bucket tooth new development
Since 2020, Liugong has launched two new bucket teeth, Liugong piece No. : 72A2985 and 72A2499, which are suitable for Liugong CLG877, CLG888 and CLG890 large loaders. The service life of this new tooth with high performance is 290 hours, while the service life of the customer's matching teeth in the mine is about 170 hours.
Willow tooling teeth: Iron teeth that can chew "hard bones"!
In 2012, the feedback rate of early wear of bucket teeth of Liugong loader was slightly higher, and customers were not satisfied with the quality of teeth. In 2013, under the leadership and organization of Liugong, the Materials Group of the Institute of New Materials of Liugong Research Institute and the Structural Parts Institute of Joint Loader Research Institute formed the bucket Teeth Project team to collect the early failure cases of bucket teeth, systematically analyze the types and characteristics of tooth failure, and improve the bucket teeth of the loader by using CAE simulation and analysis technology. Minimize the feedback rate of early failure of Loader Bucket Teeth.
Although some improvements have been made, the Bucket Teeth project team has realized that it is not enough to solve the problem of early fracture failure of bucket teeth. Compared with the benchmarking teeth, the teeth of Liugong bucket teeth have not been solved. In 2014, the project team conducted research on the chemical composition, mechanical properties and wear resistance of materials. Under the leadership of senior technical expert Meng Qiuhong, the project team established school-enterprise cooperation with Sichuan University to jointly fight against bucket teeth materials. Grinding has carried on the thorough fundamental theory research.
Through many tests and comparisons, the tooth project team has applied microalloying technology to the development of tooth shape materials, successfully developed a multi-component composite microalloying tooth shape wear-resistant material formula and provided a matching heat treatment process. After the successful trial production of the new material teeth, the service life test will be carried out on the same stage with the competitors' bucket teeth. The wear life of the new material bucket teeth has reached the level of the top teeth in the industry. However, the top teeth in the industry are actually sold at 8-10 times the price of Liugong teeth. It's fair to say that the Tooth project team has achieved a milestone.
The development of new dental materials has strengthened the idea and determination of the dental materials project team to develop a new series of Liugong teeth. From 2015 to 2016, the bucket tooth project team visited more than 10 operation sites such as quarry, sand mining, tunnel, cement mine and iron mine, and found that the bucket tooth life difference was as much as 20 times. Different working conditions. The gear project team collected and analyzed the force characteristics and wear characteristics of loader teeth under different working conditions, and developed universal teeth, heavy load teeth and penetration pieces suitable for different working conditions. Type in the tooth.
The new Wanxiang teeth, installed at Liusteel Mining Company, will last 2.8 times longer than the existing teeth. The heavy new teeth were installed in Fufeng Heidelberg Cement Mine in Shaanxi Province, and their service life is 2.34 times longer than that of the existing teeth. In the installation test of Zhangchangchang Railway tunnel of Hunan Railway 18th Bureau, the new teeth have been used for 1500 hours, and the performance is good, while the existing bucket teeth in this service life is only 600 hours.
The SUCCESSFUL DEVELOPMENT OF THE NEW HIGH PERFORMANCE TEETH INDICATES THAT THE "IRON TEETH" OF LIUGONG LOADER CAN MEET THE CHALLENGES OF VARIOUS HARSH WORKING conditions, and THE working life is greatly improved.
Liugong's new teeth have won the trust of customers even before they hit the market. Customers have scales in mind. As the main wearing part of the working device, the application of the new high performance bucket teeth can directly reduce the maintenance cost of the bucket teeth by more than 50%, and create real profits. Liugong new teeth show excellent wear resistance in the test stage. In the minds of customers, LIugong brand's high performance brand building has left a deep impression on them.
The new high performance gear transmission devices suitable for various working conditions have entered the application and promotion stage in Liugong. This year will take the lead in the CLG877, CLG888, CLG890 large loader promotion, and gradually to other series of loaders and accessories market promotion. Liugong New Teeth has excellent cost performance and strong market competitiveness, and will provide strong support for Liugong's high quality products.
