Spinning technology1. Spinning technology basic conceptsMetal spinning the basic principles of technology similar to the ancient pottery production technology. Spiral forming of the general axially symmetrical parts for cylindrical thing or a disc, the spinning semifinished product usually thick wall cylinder a round or sheet metal. Spinning machine the principle and structure similar to metal cutting lathes. In the lathe big dragging plate position, the design becomes a axial movement with the power of the rotary wheel frame, secure in the spin on the shelf wheel spin round can make radial motion； And the spindle of coaxial connecting a mandrel (axis), spinning semifinished product set in the core mold (axis)； Spin round through and set in the core mold (axis) of the blank of contact, generate friction reverse passive rotation； At the same time, and the wheel frame in axial thrust large under the action of oil cylinder, axial movement. Rotary wheel frame in axial, rotary wheel in radial force under the common function of, point by point blank surface implementation of continuous plastic deformation. In the end the position of the top bracket lathe, the design with the same axis of the main shaft into the top hydraulic cylinder, hydraulic cylinder to set in the core mold (axis) of the blank on end axial thrust.Spinning moulding common spinning and powerful spinning moulding two kinds. Dont change the blank thickness, change the shape of a blank spinning that ordinary spinning molding； That is blank thickness change, and change the shape of the blank spinning that powerful spinning moulding. Powerful spinning moulding pressure great need spin, spinning machine structure in general is more complex. Powerful spinning and spinning wheel in forming mobile direction and the metal flow direction, divided into is the spin and spin. Spin round the direction of the mobile metal flow in the same direction, that is spinning； Conversely, called reverse spin. The same kind of material, the spin the larger pressure molding spin. Use which kinds of spinning mode forming, according to the shape of the parts and technology requirements for sure.Spinning machine selection by spinning craft and various molding process conditions required. Spinning machine points of powerful spinning machine and ordinary spinning machine two types. Powerful spinning machine again points two rollers and three spinning wheel. And used for special parts of spinning spinning machine, such as hot spinning machine, steel ball spinning machine, etc.Chinas metal spinning moulding technology development history nearly forty years, and in the defence industry application is extensive research, the application level is high, especially in spinning production process and equipment, has been a leading domestic status. Spinning machine design and manufacturing capability is strong.2. Spinning technology introductionWhat is called a spinning technology, also called metal spinning forming technology, through the rotation to force a point by point to the line by line to the face, and in a certain direction to give certain pressure makes the metal material along the direction deformation and flow and forming a shape of the technology. Here, metal materials must have plastic deformation or flow properties, spinning forming not equal plastic deformation, it is the collection plastic deformation and flow deformation complex process, especially need to point out is, What we call spinning forming technology is not a single powerful spinning and spinning common, it is a combination of both； Powerful spinning used for various tube, the cone, different form of spinning forming shell processing techniques, it is a more old mature method and process, also called rolling method.In the area of mechanical products in how to save raw materials but it can improve product quality, reduce the weight of the product but can prolong service life, reduce the production cost and energy consumption but you can reduce processing time has been paid attention.For example V type pulley (films V type belt wheel) is very versatile one of the mechanical transmission parts, if can by steel plate molding is of great significance. Ban system with the traditional pulley than cast iron pulley, raw materials can save more than 70%. Ban metal material by the spinning of tensile-forming Ban system spinning pulley is the latest of the best with round structure. This not only with round with Syria on advantages, and no environmental pollution, especially in automobiles, tractors, harvester, air compressor and so on many kinds of mechanical product is used widely. The steel Ban blank in special pulley spinning machine that produced by point blank line by line to, to the plastic deformation and manufactured. Spinning wheel with general have three basic types: the folding belt wheel, split type belt wheel and rolling type V belt round more (also referred to as many wedge with wheel).Spinning wheel and cast iron compared with the advantages of the pulley is made of spinning craft (a chipless machining), structure light, province materials, and inertia small, is a quarter of new material and energy saving products. High production efficiency (every minute 2 4 pieces processing), balance performance is good, general no balance. The materials streamline dont have been cut off, surface production cold hardening, improve theCDC-S60 vertical CNC spinning machine toolsBelt wheel spinning into form technology and equipment is a advanced technology, with wheels spinning craft has been made on the folding pulleys, the split type pulleys, rolling type V belt wheel and more combined with a series of scientific research achievements wheel, in theory and practice to solve the two aspects of the spinning forming various technical problems, and successfully used for production. But with Germanys spinning technology in China still needs to chase dare, because, in many products also need to be imported, especially in some parts of the car.Spinning product introductionCDC-S series CNC spinning machine is the production of spinning the pulley of special equipment. Spinning a pulley is a new technology products, has been widely used in automobile engine, such as motor wheel, water pump wheels, air conditioning wheel and fan wheel etc. According to the slot of pulley type and processing technology can be divided into three categories: split wheel, folding round and round wedge. As the three categories of spinning the structure characteristics of the pulley is different, its processing technology is not the same.The long the selection of material thickness of 2 6 mm, generally are 3 mm. The deep drawing and pressing method blocking, in spinning machine processing forming. Due to the tooth shape in the wall thickness of the material is used on the way to squeeze produce metal flow and plastic deformation and form, so the influence factors on the quality of the final product is many, including lower die, rotary wheel, process parameters, materials, etc. After the analysis of the technology of and die design will be detailed in the introduction.Fold the the selection of material thickness of 1.5 2.5 mm, also is the deep drawing and pressing method blocking, and in spinning machine processing forming. Because the forming process in folding round metal flow didnt happen, so the process is simple, the influence factors on the quality of the little.Split wheel thickness of the material for 2 4 mm, generally USES a cutting blocking, in the spinning wheel with spin on the material from the thickness of the split in half after plastic and forming. Due to its processing technology is simple, the influence factors on the quality of the little also, the most is the plane of blank itself by the influence degree. So hedge to stamping mould request is higher.旋压技术基本概念金属旋压技术的基本原理相似于古代的制陶生产技术。旋压成型的零件一般为回转体筒形件或碟形件，旋压件毛坯通常为厚壁筒形件或圆形板料。旋压机的原理与结构类似于金属切削车床。在车床大拖板的位置，设计成带有有轴向运动动力的旋轮架，固定在旋轮架上的旋轮可作径向移动；与主轴同轴联接的是一芯模(轴)，旋压毛坯套在芯模(轴)上；旋轮通过与套在芯模(轴)上的毛坯接触产生的摩擦力反向被动旋转；与此同时，旋轮架在轴向大推力油缸的作用下，作轴向运动。旋轮架在轴向、旋轮在径向力的共同作用下，对坯料表面实施逐点连续塑性变形。在车床尾顶支架的位置上，设计成与主轴同一轴线的尾顶液压缸，液压缸对套在芯模(轴)上的坯料端面施加轴向推力。 旋压成型有普通旋压和强力旋压成型 。变坯料厚 ， 变坯料形 的旋压 普通旋压成型； 变坯料厚 , 变坯料形 的旋压 强力旋压成型。强力旋压成型 的旋压力 大,旋压机的结构一般 。强力旋压成型 旋轮移动的 向与金属 动的 向， 为旋和反旋。旋轮移动的 向与金属 动的 向相同， 旋；反 ， 为反旋。同一 料，反旋成型 的旋压力 大。 用 旋压 成型, 零件的形 和 定。 旋压机的型旋压 成型 件 定。旋压机 强力旋压机和普通旋压机大类型。强力旋压机 旋轮和currency1旋轮。有用于“零件旋压的旋压机， 旋压机、fifl旋压机 。 金属旋压成型技术的 ”，在 的 用 为， 用 ，“是在旋压成型 面， 于 位。旋压机的设计和制 力强。旋压技术 旋压技术， 金属旋压成形技术，通过旋转 力点点 线线 面，同时在 向 一定的压力 金属 料 一 向变形和 动成型一形 的技术。 ，金属 料 有塑性变形或 动性 ，旋压成形 同塑性变形， 是 塑性变形和 动变形的 过，“ 的是，的旋压成形技术 是 一的强力旋压和普通旋压， 是 的结 ；强力旋压用于 筒、体 形体的旋压成型 体的加 技术，是一 的成 的和 ， 压 。 在机产 原 料 提产质量，减轻产的重量
