On June 22, the reporter visited the Xugong Mixing Machinery Manufacturing Base in Xuzhou Economic and Technological Development Zone. The factory area and the workshop were very tidy. In the workshop, due to the implementation of rustless production, coupled with sound ventilation facilities, an automated production line is pleasing to the eye. This new base is also equipped with a modern electrical branch dedicated to providing XMG's pumping and mixing machinery with "neuronal" control cabinets for equipment operation.
With the completion and production of the two bases for base pumping machinery and mixing machinery, the industrialization pattern of “three-vehicle and two-station†concrete construction of Xugong Concrete Machinery was formally formed, and the industrial structure and production capacity were upgraded. XCMG is in the field of concrete machinery. years of experience and hard work will be a full-blown energy <br> <br> highest level of intelligent industry
The new base project covers an area of ​​360 mu, a new factory building of 100,000 square meters, and a total investment of 2 billion yuan in technical innovation. The project started construction on May 6 last year. The entire project adopts the principle of "concurrent engineering". Each subproject cooperates in design and construction in parallel. It is the construction project with the fastest progress and the shortest construction period for similar projects in the industry. According to the on-site assembly characteristics of the mixing machinery products, the process routes are properly divided according to the technical characteristics of the parts, a new concept of "shortest logistics" is proposed, and the "'E' layout" of the logistics is planned for the manufacture of the mixing machinery products, thereby resulting in a The closed production process realizes the rapid diversion from one raw material processing unit to multiple types of concrete mixing product manufacturing lines, and realizes the lean logistics of the concrete mixing product manufacturing process.
In Xugong’s many sections, the concrete construction machinery segment is a rising star, but it is undoubtedly a “potential shareâ€. Two new bases for pumping and mixing stations were completed and put into operation simultaneously. The world’s concrete giant Shi Weiying “joined†Xugong Group, and Xugong Concrete Machinery. The goal has been to lead the industry. The new base has adopted advanced laser cutting machines, precision plasma cutting machines, robotic steel cutting machines, angle steel joints and other advanced and efficient sheet and profile blanking equipment, and has applied high efficiency such as co-edge, continuous cutting, automatic pre-punching and common holes. Nesting process technology, to achieve cutting "high efficiency, high quality, low consumption" and improve machining accuracy and efficiency. The use of domestic advanced dry roller hydraulic group for automatic seam, straight seam welding technology and automatic welding technology such as mixing robot robot welding workstation, improve the automatic welding rate and welding efficiency. The use of high-precision equipment such as double-faced counterweight machining centers and gantry drilling and milling machining centers ensures the processing quality. Install advanced and efficient board chain assembly lines in the industry, configure pneumatic and electric tools across the line, reduce labor intensity and increase production efficiency.
No rust production welding lean manufacturing
Production and mixing machinery requires a large number of steel plates, angle irons, etc. In order to achieve rustless production and improve product quality, the new base must perform blasting and other procedures for rust removal and drying after processing steel materials that require bending and welding. Achieve rustless welding. The new base will introduce large-scale steel plate and profile pretreatment equipment to achieve rust-free welding, and the weld will be tighter and stronger. For a large number of sheet materials that need to be painted, rust removal is also required.
The new base was the first in the industry to design and form three welding lines for concrete drums and one sub-frame welding line, which improved the welding efficiency of the product. Designed to form 3 component spraying lines, applying a large-scale water spinner spray booth, greatly improving the spraying quality and spraying efficiency. The new base also designed and completed a concrete mixer truck assembly line and a mixing host assembly line, which greatly increased the assembly efficiency of the mixing machine.
In order to ensure the stability of the quality, the detection equipment such as the articulated arm coordinate measuring machine is used in the processing to ensure the accuracy of the manufacturing process. During the assembly process, an on-line test station was set up to carry out the no-load test of the mixer truck. In the commissioning field, a simulation test and test field was built, and the loading test of the mixer truck could be carried out.
The new base also comprehensively promotes the implementation of lean manufacturing. According to the short welding procedure of the structural parts of the concrete mixing plant and the fact that most of the workpieces do not need to be assembled, the short-span, multi-span process layout scheme is adopted to form large, medium, and small pieces of welding zone. And corresponding to the coating line, and sent to the shipping yard nearest to ensure that the process is reasonable, professional and orderly.
Whoever has mastered the research and development and manufacturing technologies of core and key components will master the future of the development of construction machinery industry. In the planning process of the Xugong Concrete Mixing Machinery Industrial Base, the process design of the core and key components was particularly highlighted, and the core manufacturing technology advantages of the XCMG concrete machinery industry were formed. Focusing on the future of intelligent manufacturing and intelligent control technology, Xugong Mixing Machinery Manufacturing Co., Ltd. has independently set up an electrical professional branch mainly supplying concrete machinery.
The control system and the mixing master are the “brains†and “hearts†of the concrete machinery and equipment, and their importance is evident from the title. Xugong Construction Machinery set up the first “electric branch factory†in the industry, which has completely changed the current status of the stall-style production of the current electrical system in the industry. The factory building of the electric branch factory is designed and designed according to the industrialization, process, and information standards. The design completed one control system harness assembly line and two control system control cabinet assembly lines to achieve professional production of electrical systems and formed an advanced, reliable, and efficient control system manufacturing technology.
The new base's electrical assembly line is controlled by a modern MES control system. The host's online and offline plans and workstation anomalies are visualized through LED display screens, enabling the production management information to be dynamically updated and real-time mastered. The commissioning station is equipped with a visual automatic detection and control system, which reduces measurement errors caused by personnel operations.
