Idler mandrel is the rubber conveyor belt
with the most consumption is also a very key (interpretation: an important part of the metaphor) rotating parts, its processing quality, service cycle on the belt conveyor operation efficiency, service life and reliability have a great impact. The sandwich canvas between nylon conveyor belt is nylon canvas. Nylon CONVEYOR BELT has the characteristics of thin belt body, high strength, impact resistance, good slotting, large interlayer adhesion, excellent flexion and long service life, etc. It is suitable for conveying materials in medium and long distance, high load and high speed, widely used in mining, coal yard, chemical industry, metallurgy, construction, port and other departments. Through the design of the combined drilling and milling machine in the production line of the idler mandrel, the automatic manufacturing of the production process is realized. It has high practical value: reduce the use of manpower, reduce the labor intensity of workers, reduce the area of equipment layout, shorten the production cycle, reduce auxiliary transportation tools, reduce the workload of non-production, reduce energy consumption, save raw materials; Improve the production efficiency, manshaft processing quality, accuracy, service life and processing efficiency, so as to improve the rubber conveyor belt product quality and work efficiency, and the conveyor belt speed liquidity and reduce the cost of finished products, so that the production efficiency of enterprises significantly improved. It can better meet the demand of social mass mandrel.
In general, it has high theoretical value and social practical value for the design and transformation of drilling and milling combined machine tools in idler mandrel production line.
Conveyor belt is used for belt conveyor belt bearing and transporting materials in the role of rubber and fiber, metal composite products, or plastic and fabric composite products. Conveyor belt is widely used in cement, coking, metallurgy, chemical industry, steel and other industries in the conveying distance is short, small throughput occasions. Belt conveyor in the agricultural, industrial and mining enterprises, and transportation is widely used for conveying of various solid block and powder materials or items, conveyor belt can be continuous, high efficiency, the transport of large dip Angle, conveyor operation safety, conveyor belt use is simple, easy maintenance, low freight rates, and can reduce the engineering cost, shorten the transportation distance, economically. It is worth further study. Drilling and milling combined machine tool is a kind of special and efficient (refers to the high efficiency) automation technical equipment, is the domestic special processing roller mandrel machine tool. This machine tool has the characteristics of multi parts processing, which can improve the precision of parts processing and improve the working efficiency. The idler mandrel is one of the important parts of belt conveyor, its structural parameters and processing technology level greatly affect the conveyor belt dependability and life of the whole machine. Of course, there are many ways to process roller shaft, but the shape and position accuracy of rubber conveyor belt is difficult to ensure, and the drilling and milling machining combination machine tool can not only ensure several accuracy requirements. And can ensure the accuracy of the requirements. It is still the key equipment to achieve high efficiency, high quality and economic production of large quantities of mechanical products.
Some important technical problems of drilling and milling combined machine tools have been studied continuously from the 1950s to the 1980s, and many achievements have been made. However, many problems have not been studied deeply because of their strong specificity, special characteristics, difficulties in research, and the research funds are related to economic benefits. Large inclination conveyor belt in the use of general first empty machine to start, so as to avoid motor overload and large inclination conveyor belt skid, stop before all the material should be unloaded. 5. In the use of tension should not be too large, should not slip with the transmission roller and the material is not transitional premise, to ensure the minimum tension work. White conveyor belt manufacturers according to the different use environment, divided into ordinary conveyor belt including (common type, heat resistant type, flame resistant type, burn resistant type, acid and alkali resistant type, oil resistant type), heat resistant conveyor belt, cold resistant conveyor belt, acid and alkali resistant conveyor belt, oil resistant conveyor belt, food conveyor belt and other models. Among them, the minimum thickness of glue covering the ordinary conveyor belt and food conveyor belt is 3.0mm, and the minimum thickness of glue covering the bottom is 1.5mm. Heat resistant conveyor belt, cold resistant conveyor belt, acid and alkali resistant conveyor belt, oil resistant conveyor belt covered with rubber minimum thickness of 4.5mm, the bottom covered with rubber minimum 2.0mm. According to the specific conditions of environmental use, The thickness of the upper and lower covering glued is increased by 1.5mm.. At present, the design of modular machine tools is more or less based on experience and not completely based on science.
