PDF Metal Spinning- Design Consideration and parameter of spinning process.
Hot spinning refers to the process of spinning a piece of metal on a lathe while a high beam of heat is directed to the workpiece. After the workpiece is heated, the subject metal is then shaped whereby the lathe is pressed against the heated surface. Necking or reduction of the diameter can still be achieved through the hot spinning technique. Here, the spinning process is considered as a plane strain process, and the deformations are expressed by the diameter of the workpiece, and the spinnability is evaluated by the forming limit.

For this paper, spinning is taken as a rotational forming process that does not set out to change the wall thickness. Both the blank and the finished product have roughly the same thickness. The objective of changing the shape of the blank to a new desired product shape is common to spinning and deep drawing. The general spinning process is as follows: Before spinning, the spindle fixes core by a fixture. and, the top of the tail exerts certain clamping force. Meanwhile, The blank fixes on the core die, to clamp the blank with the tail top. The spinning process frequently requires a series of passes to complete the formed part. As each pass is made the metal is stretched, thinning out the material as a result. Thinning out is typical of the conventional spinning process but it can be minimized when required. Shear Spinning.

4 Shapes Made through Metal Spinning. Spin forming is the process of creating shaped metal pieces, usually rounded in shape, on a lathe or with other metal spinning tools. Spun metal has surprising strength and can be made into a variety of shapes. Although many factories use molds, rollers, or presses to create metal objects, many factories still use the process of spin forming aluminum.

The process accurately controls the profile of the neck while delivering controlled wall thickness and repeatability. Hot spinning produces seamless, high-precision, rotationally symmetrical shapes with very accurate profiles and wall thicknesses. Parts formed by hot spinning are: cylindrical conical contoured. The spinning process of thermotropic LC polymers is typically carried out through conventional melt-spinning extrusion. During extrusion through very small holes, the shear flow induces an alignment of the LC domains in the flow direction: in this way, the extruded fiber is characterized by a highly oriented structure as depicted in Fig. 17.49. The internal diameter of parts formed by metal spinning should be controlled within 2.5m Spinning Process Step 1: Fix the cut circular metal plate on the machine mandrel.

Spinning process is an initial step to produce textile layout such as garments, fabric, home textile and so on. People used to convert fibers into yarn i.e. the spinning process by hand before a couple of decades which has now been mostly replaced by advanced technology of mechanical spinning carried in textile mills. Different spinning methods are available in making yarns, including ring-spun, rotor-spun, twistless, wrap-spun and core-spun yarns.. Ring-spun yarns: This is the most widely used method of staple-fibre yarn production. The fibres are twisted around each other to give strength to the yarn. Rotor-spun yarns: These are similar to ring-spun yarns and usually made from short staple fibres. Power spinning is a single-point high-pressure forming process which is usually studied with ideal regular blank. However, in some cases, the blank adopted in this process is from conventional spinning process with non-uniform wall thickness and springback. Therefore, the forming accuracy cannot be guaranteed because of the irregular blank. In this paper, cone, step, and arc rollers are.

In fact, flow forming can be considered to be a specialized kind of spinning process. Both metal spinning and flow forming can make workpieces from just a few inches in diameter up to several feet in diameter and lengths. Flow forming today produces parts for the nuclear, oil and gas, chemical, and medical industries, among others. Steps in Spinning Process. Step 1Metal Forming. This step involves the laying down of the material onto the mandrel. It is accomplished with short inside to outside moves.Material gets easier to form as the part is closer to completion. Steps In Sheet Metal Forming Process. Step 2Trimming. Parts having been spun are trimmed at the end to. Blank thickness is nothing but thickness of blank.The process of metal spinning is capable of forming workpiece with thickness of 0.5 mm to 30mm. To obtain uniform thickness during a spinning it required high speed ratio but this will reduce the geometrical accuracy which applicable for shear spinning.
Metal Sheet Spinning process | Sheetmetal Forming.
Spinning is a process used to produce an axis-symmetric hollow shape by the application of lateral pressure from a forming tool, to a rapidly revolving circular blank of sheet material, causing it to assume the shape of a former that is rotating with it. The principles of flow turning. Spinning is a sheet metal forming process in which a metal blank is pressed over a rotating chuck or form mandrel with the help pressing tool to obtain axisymmetric hollow shell. The sheet metal parts that have circular cross-section can be made by this process.

Spinning than in press forming. Manual metal spinning and power spinning are generally in competition with pressing and deep drawing. Equipment for Manual SpinningLathes and Tooling. A simple tool and sheet preform setup for manual metal spinning is shown in Fig. 5a. The forming mandrel is mounted on the headstock of a lathe. The circular. The typical spinning process heats the preform to provide the required ductility and often distorts the final part during cooling. Flow forming is a cold forming process, which ensures the final part#x27;s controlled characteristics are to design with no distortion. Metal spinning and flow forming are similar processes. The metal spinning process is a forming process used to produce circular hollow metal parts. To produce a part, a metal disc is revolved on a specialized lathe, while held against a spinning block, or mandrel, with a follower. As the disc rotates, spinning tools or rollers are used to force the disc onto the spinning block or mandrel.

Spinning is a manufacturing technique for obtaining revolution metal parts. The part is obtained from a disc. The material is function of the use domain. The disk is formed gradually on a tooling having the specific shape of the part to get. The assembly is rotated by clamping of the disc against the tooling by means of a tailstock. According to [3], the traditional term #x27;spinning#x27; encompasses, as a general concept, a group of forming processes for the production of rotationally symmetrical hollow shapes. Essentially, all spinning techniques involve rotating a workpiece clamped onto a chuck while the spinning tools approach the workpiece and deform it to the required shape. Spinning is manufacturing process for creating polymer fibers. It is a specialized form of extrusion that uses a spinneret to form multiple continuous filaments. There are four types of spinning for polymer; wet, dry, melt, and gel spinning. First, the polymer being spun must be converted into a fluid state.
