The spiral blade cold rolling mill is an advanced equipment for continuously rolling blades with strip steel. It can roll out various specifications by adjusting the adjustment positions (roll offset, feeding height, rolling pressure, guide wheels, etc.) Leaves. At present, the methods of manufacturing blades in China include: single-piece stamping and welding forming, extrusion forming, winding forming, cold rolling forming and other methods. Among them, the cold rolling forming method has the advantages of high production efficiency, saving raw materials, good blade quality, high hardness, and good wear resistance. The factors that affect the rolling shape include the material and thickness of the strip, the offset size of the roll, the feeding height, the rolling pressure of the roll, the difference in the specifications of the guide wheel and the blade, and the increase in the temperature of the roll during the rolling process, etc. Many factors. After years of unremitting efforts, our company has developed this continuous cold-rolled spiral blade, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
The continuous rolling type spiral blade effectively changes the traditional manual welding blade processing technology, which is domestic. It is the main part of the screw conveyor, which can be widely used in flour mills, food factories, cigar, oil mills, rice fields in the grain and oil processing industry; agricultural machinery, corn threshers, wheat harvesters, and rice harvesters in the harvest industry And chemical, building materials, light industry and other industries. The rolled spiral blade has good technical performance after cold rolling and hardening, and the surface is flat and smooth, wear-resistant and durable.
The material is rotated together with the spiral tube to realize the forward movement of the material, just as the non-rotating screw moves in translation along the rotating nut, so as to achieve the purpose of conveying the material. The machine has low energy consumption and low maintenance costs; when feeding at the end, it can meet the requirements of uneven feeding, and can complete various process requirements such as conveying, mixing and mixing at the same time. When the material enters too much, it will not cause jamming; it is convenient for more Point loading and unloading can transport materials with higher temperature. It is suitable for horizontal conveying of high-temperature materials; it has good adaptability to materials with high temperature, uneven feeding, anti-breaking requirements, anti-pollution requirements, and processes that require multiple points of loading and unloading. Practice has proved that it is effective in conveying materials such as cement clinker, dry limestone, phosphate rock, ilmenite powder, coal and slag. The particle size of the material added from the end feed port should not be greater than 1/4 of the spiral diameter; the particle size of the material fed from the middle feed port should not be greater than 30 mm. To ensure that the cylinder does not deform.
The surface of the blade has solid surface, belt surface, blade surface and other types according to the different materials to be conveyed. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the axial reaction force of the screw with the material. When the length of the machine is long, an intermediate suspension bearing should be added. Screw conveyor, commonly known as auger, is a widely used conveying equipment in the mineral, feed, grain and oil, and construction industries. It is divided from the perspective of the displacement direction of the conveying material. Screw conveyors are divided into horizontal screw conveyors and vertical screw conveyors. There are two types of machines, mainly used for horizontal conveying and vertical lifting of various powder, granular and small lumps and other loose materials. The spiral body of this product has small diameter, high speed, large conveying capacity, high precision and good conveying conditions. Simple operation and easy maintenance; for a conveyor, it can be loaded or unloaded at multiple points on the conveying line; during the process of conveying materials, materials can be mixed, stirred or cooled at the same time, and the rigidity of the shell can bear a certain amount External force.
Rinse with clean water, repeat this once, and clean the cooling system with clean water. The above is a brief introduction to the processing and cleaning process of the spiral blade. As the main part of the mechanical equipment, the spiral blade must be cleaned in time and regularly inspected during use, so as to ensure the normal use of the spiral blade. The spiral blade harvester is a common agricultural machine that can complete the threshing operation as soon as possible, which is convenient for the production of agricultural products. The use of the harvester can achieve a more user-friendly effect. The harvester will adjust the unbalanced, linked element of the spiral blade. The position of the paddle wheel is too far from the cutting table to enter the spiral blade, the cut crop cannot be disturbed in real time, and the integrated group may also be unbalanced. Improper adjustment, such as cutting machine feed spiral blade 10 mm from the plate gap. Because of the unbalanced wear of the spiral blades of countless binder augers, it depends on the poorer edge wear of both sides in the middle of the feed inlet. At that time, the loss of mediation was that the distance between the spiral blade and the bottom plate was too poor.
The spiral blade has three forms: solid spiral surface, ribbon spiral surface and blade spiral surface. Among them, the blade spiral surface is relatively less used, and is mainly used for conveying materials with high viscosity and compressibility. This spiral suspension surface type is used in In the process of completing the conveying operation, it has and completes the functions of mixing and mixing materials at the same time.
