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.旋壓技術(shù)基本概念金屬旋壓技術(shù)的基本原理相似于古代的制陶生產(chǎn)技術(shù)。旋壓成型的零件一般為回轉(zhuǎn)體筒形件或碟形件，旋壓件毛坯通常為厚壁筒形件或圓形板料。旋壓機的原理與結(jié)構(gòu)類似于金屬切削車床。在車床大拖板的位置，設(shè)計成帶有有軸向運動動力的旋輪架，固定在旋輪架上的旋輪可作徑向移動；與主軸同軸聯(lián)接的是一芯模(軸)，旋壓毛坯套在芯模(軸)上；旋輪通過與套在芯模(軸)上的毛坯接觸產(chǎn)生的摩擦力反向被動旋轉(zhuǎn)；與此同時，旋輪架在軸向大推力油缸的作用下，作軸向運動。旋輪架在軸向、旋輪在徑向力的共同作用下，對坯料表面實施逐點連續(xù)塑性變形。在車床尾頂支架的位置上，設(shè)計成與主軸同一軸線的尾頂液壓缸，液壓缸對套在芯模(軸)上的坯料端面施加軸向推力。 旋壓成型有普通旋壓和強力旋壓成型 。變坯料厚 ， 變坯料形 的旋壓 普通旋壓成型； 變坯料厚 , 變坯料形 的旋壓 強力旋壓成型。強力旋壓成型 的旋壓力 大,旋壓機的結(jié)構(gòu)一般 。強力旋壓成型 旋輪移動的 向與金屬 動的 向， 為旋和反旋。旋輪移動的 向與金屬 動的 向相同， 旋；反 ， 為反旋。同一 料，反旋成型 的旋壓力 大。 用 旋壓 成型, 零件的形 和 定。 旋壓機的型旋壓 成型 件 定。旋壓機 強力旋壓機和普通旋壓機大類型。強力旋壓機 旋輪和currency1旋輪。有用于“零件旋壓的旋壓機， 旋壓機、fifl旋壓機 。 金屬旋壓成型技術(shù)的 ”，在 的 用 為， 用 ，“是在旋壓成型 面， 于 位。旋壓機的設(shè)計和制 力強。旋壓技術(shù) 旋壓技術(shù)， 金屬旋壓成形技術(shù)，通過旋轉(zhuǎn) 力點點 線線 面，同時在 向 一定的壓力 金屬 料 一 向變形和 動成型一形 的技術(shù)。 ，金屬 料 有塑性變形或 動性 ，旋壓成形 同塑性變形， 是 塑性變形和 動變形的 過，“ 的是，的旋壓成形技術(shù) 是 一的強力旋壓和普通旋壓， 是 的結(jié) ；強力旋壓用于 筒、體 形體的旋壓成型 體的加 技術(shù)，是一 的成 的和 ， 壓 。 在機產(chǎn) 原 料 提產(chǎn)質(zhì)量，減輕產(chǎn)的重量
