The method of claim 1 wherein the mounting pad formed by stamping is made of a width less than the width of the workpiece. (d) whereby step (c) will not cause departure from the initial workpiece outline. NATIONSBANK OF TEXAS, N.A. Though these days the manufacturers make the ceiling fan buying process way easier by making multiple color and size variations of one single ceiling fan model, still the below-discussed points are necessary as well. FIG. A method of making a curved sheet metal fan blade from a sheet metal workpiece which is to be flattened over a portion thereof for subsequent superposed attachment to a flat mounting arm, including the steps of: (a) forming a workpiece of generally cylindrical contour and of a desired outline. This is done by simultaneously stamping the cylindrical blank or workpiece with a longitudinally running rib while the flat portion is formed. Make sure the fan blades are attached firmly to the brackets by tightening the screws. High-quality ceiling fan blades, on the other hand, are made from furniture-grade, real hardwood, many with hand-carved intricate designs. Owner name: Haiku’s superior design and technology has garnered praise and awards from publications and organizations like Popular Science, red dot, Inc. and IDSA. A ceiling fan blade includes a foamed layer, two paper layers, and two cover layers. Then, a stamping die set is formed which has a configuration similar to that shown at FIG. LPG operated ovens for baking ensures high heat transfer efficiency & pollution-free environment. 3. According to the practice of this invention such a final step is eliminated.

Free format text: Modern testing facilities for 100% motor & blade verification before packing. If your blades have begun to warp you will want to replace them. 4 is a view taken along section 4--4 of FIG. Internal product audit system at each stage of manufacturing to enhance customer delight. The term cylindrical, as used in the claims, is intended to embrace conical shapes as well as cylindrical shapes. Gangways/passages are wide and clearly demarcated for easy/free movement of materials. 2 is a perspective view of a cylindrical workpiece from which the fan blade of FIG. FIG. In the manufacturing procedure, such a blade needs to go through many processing steps such as cutting, planing, multi polishing, finishing, painting and printing or covering with printed paper, etc. It would be easy to go into great detail about how th… The ceiling fan in various models, sizes and designs which can also customized as per customer's requirement. SCHWITZER U.S. INC., NORTH CAROLINA, Free format text: Products. On line gauging with automation for monitoring SPC. Do the same thing with the fan brackets where they are attached to the fan motor. ;REEL/FRAME:008153/0249, Free format text: The first electrically powered ceiling fan was introduced in … 1.5K views View 1 Upvoter The steel used for making the blade is purchased from HINDALCO . The mounting pad 14 is attached to the end of a flat spider arm, not illustrated, by passing the fasteners through the apertures 20 to thereby secure the blade to the spider arm. About Us |
FIG. First of all the the steel wrap is unwinded and than it is cut in the desired shape depending upon the style. 2 is now placed between the stamping dies and the stamping operation carried out by bringing the dies together. ... engineering and manufacturing of ceiling fans. This invention relates to a process for forming a sheet metal fan blade of a type particularly adapted to be employed in conjunction with the fan in an automotive cooling system. Modern testing facilities for 100% motor & blade verification before packing. The blade is to be attached to a flat spider arm of a fan hub. It is best for all ceiling fan blades to be at the same height from the ceiling. The effectiveness of a fan can fairly simply be evaluated in terms of how good a job it does of circulating air through a room. 1 is a plan view of a completed fan blade formed in accordance with the practice of this invention. The fan blades themselves being of cylindrical form and the spider arms being flat, workers in this art have had to devise some method of further shaping of the fan blades in order that a portion thereof may be flat to thereby facilitate attachment to the spider arms. Fully integrated automation system air delivery measurement for ceiling fans. Ceiling fan consists of electric motor and blades.

This is because of the growing presence of organized retail outlets, increasing spending power and rising preference for online sales platform and modular homes are expected to boost demand for electric fans in Bangladesh over the coming years. In addition, energy to rotate the ceiling fan is reduced. As the hot air rises up, the blades of the fan slice this air and push it down. Buying a ceiling fan is also not that much tricky and complicated and needs only some very few considerations only. 5, an illustration is offered of the usual distortion which accompanies the formation of the mounting pad by typical prior-art methods. High precision & consistency in machining system ensures zero defect. (c) simultaneously flattening the workpiece by stamping at portions laterally of the rib to thereby form a flat mounting pad, the mounting pad adapted to be attached to a flat spider arm of a fan hub. FIG. This stamping has resulted in a distortion of the outline of the blank and accordingly a final blanking step has been required. They cool people effectively by introducing slow movement into the otherwise still, hot air of a room. Portions 24 and 26 denote the distortion which often accompanies such deformation. ... not available please call 1-877-332-6700 to talk with a live ceiling fan specialist who can walk you through the set up process. Similarly, the height of the rib 16 is the vertical distance between surface 25 and the lower surface of the rib, and is designated by the letter H at FIG. 3) and the numeral 25 denoting the lower surface of the pad 14, the depth of the pad is the difference in vertical height between surfaces 22 and 25.
