  • Patent number: 9156132
    Abstract: Disclosed herein is a surface treatment machine that enables the inhibition or reduction of residual abrasives that remain on a workpiece that has been surface treated. An H steel (a workpiece to be treated) 12 is conveyed by means of a conveying device 20. Blasting devices 24A, 24B are then projected abrasives on to the conveying H steel such that it is surface treated. In the downstream of the blasting devices 24A, 24B along the conveying direction, a blowing port 30A of an air blower 30 is located above a conveying path to blow gas to the upper surface 112A of the H steel 12 such that the abrasives on the H steel 12 are blown off and removed therefrom.

  • Patent number: 8328603
    Abstract: An apparatus for stress shot peening of a coil spring is disclosed. The apparatus of the present invention is constructed such that coil springs, which are compressed and clamped by corresponding spring clamping units (20) facing each other, are rotated on their own axes and are simultaneously supplied into the shot room (10) for shot peening. Therefore, the present invention can markedly enhance the internal stress of the coil spring, compared to a coil spring treated by the conventional shot peening apparatus. Furthermore, in the present invention, because the coil springs are clamped by the corresponding spring clamping units facing each other and are simultaneously rotated and moved into the shot room for shot peening, various kinds of side load coil springs, as well as a typical cylindrical coil spring, can be evenly treated throughout the entire surface thereof by shot peening.

    Abstract: In a method for estimating an entrance angle of a V-ribbed belt from a flat pulley to a V-ribbed pulley, the entrance angle is estimated easily at a stage of pulley layout design. The V-ribbed belt 10 forms a track which enters at an entrance angle of approximately zero degree (substantially perpendicular to a plane that includes an axis 3a of rotation) into the flat pulley 3, is wound along the outer peripheral face of the flat pulley 3 without deviating in the axial direction thereof, and extends substantially linearly from a winding end point c at the flat pulley 3 to a winding start point d at a drive pulley 1. The entrance angle ? of the V-ribbed belt 10 from the flat pulley 3 to the drive pulley 1 is obtained on the basis of the track of the V-ribbed belt by, for example, a three-dimensional CAD or the like.

  • Patent number: 6656017
    Abstract: The present invention is a method and apparatus for providing a low-cost and less complex micro-environment for treating a substrate using an impingement cryogenic or steam spray jet. A substrate and fixture is contained within an open-architecture prophylactic or cleaning cell whereupon the substrate and fixture is continuously bathed in a regenerated and re-circulating stream of filtered, inert, dry, heated and ionized atmosphere which bathes both the entire substrate and fixture. This prevents the intrusion of contaminating ambient atmospheres onto critical surfaces. The cleaning cavity is constantly regenerated and re-circulated through the cleaning cell to maintain a majority of the clean atmosphere wherein the clean cavity is pressurized slightly with a small volume of clean dry air or inert gas to prevent the intrusion of ambient atmosphere into the cleaning cell.
