Homeowners looking for ceiling fans will be spoilt for choice, from finishes of the motor housing to fan blades (microfiber, wooden, acrylic, metal or rattan blades). 1. 1, 3 and 4 is carried out in the following manner. From blade tip to blade tip. (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. is simultaneously provided with a longitudinally running rib and a flat pad portion by stamping. The workpiece of FIG. 2 and 4. Work stations are ergonomically designed for ease of operation. 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. The term cylindrical, as used in the claims, is intended to embrace conical shapes as well as cylindrical shapes. PLC controlled time cycle for transporter movement during pre-treatment process in each tank. If your blades have begun to warp you will want to replace them. 1 of the drawings, the numeral 10 denotes generally a fan blade of this invention adapted to be attached to a flat spider arm of a fan hub. The final blanking step with such prior-art procedures has involved the removal of portions 24 and 26. State-of-the-art winding process using CNC programmed winding machines. Make sure the fan blades are attached firmly to the brackets by tightening the screws. 5, an illustration is offered of the usual distortion which accompanies the formation of the mounting pad by typical prior-art methods. 1.5K views View 1 Upvoter Assembly process equipped for manufacturing 2 lac fans per month. 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. 1 with the practice of a prior method. Inclined portion 18 connects the radially outermost section of the blade with the mounting pad. Feasibility study on Ceiling fan Manufacturing Plant.
