Patent number: 8506361Abstract: A fixture for facilitating sandblasting of a generally cylindrical object includes a frame, a rotary table mounted on the frame, and a moveable blast head which can direct a flow of grit onto a cylindrical object mounted on the rotary table. The blast head may be movable vertically so that it can be extended down into the interior of a cylindrical object. The blast head may also be movable in a rotational fashion. Further the blast head may be movable in horizontal directions so that the blast head can be moved relative to a vertically extending cylindrical surface of a cylindrical object mounted on the rotary table. Controlled movements of the rotary table and the blast head allow uniform sandblasting of the cylindrical object.Type: GrantFiled: August 25, 2011Date of Patent: August 13, 2013Assignee: General Electric CompanyInventor: Stephen Michael Deak

Publication number: 20130203320Abstract: A sensor may be used to determine the presence of burrs on a workpiece, and a blasting media may be applied to the workpiece to lessen or eliminate burrs. The blasting media may be applied to the workpiece using a nozzle. The sensor may be scanned over the workpiece, and one or more burr metrics may be determined to qualify or quantify the presence of burrs. Based on the one or more burr metrics, a blasting schedule may be determined and performed. One or more characteristics of the workpiece may be checked after deburring to determine the extent of alteration, if any, of the workpiece caused by deburring.Type: ApplicationFiled: February 6, 2012Publication date: August 8, 2013Inventor: Hamid R. Ghalambor

Publication number: 20130115853Abstract: 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.Type: ApplicationFiled: March 1, 2011Publication date: May 9, 2013Inventors: Shigeru Yamamoto, Tadanobu Oyama

Patent number: 8414354Abstract: A glass manufacturing device includes a working container, a loading device, a sand blower, a shielding device, and a supporting device. The loading device is received in the working container and configured for loading a glass substrate in place. The sand blower is arranged opposite to the loading device and configured for sandblasting the glass substrate. The supporting device is used for supporting the shielding device and pressing the shielding device onto the glass substrate during the process of sandblasting. The shielding device includes a shielding cover having a number of shielding units. The shielding units are configured to shield portions of the glass substrate and prevent the portions of the glass substrate from being cut during sandblasting.Type: GrantFiled: September 29, 2010Date of Patent: April 9, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Shao-Kai Pei
