| This invention resolves the problem in which a robot of the existing method cannot efficiently carry coarse aluminum castings to a first and a second machining unit.A robot holds an untreated coarse aluminum casting that is located at a predetermined carrying-in corner with the holding means and carries it to the first machining unit. Then, at the first machining unit it holds the treated coarse aluminum casting that has been treated by the first machining unit with the holding means as well as transferring the untreated coarse aluminum casting from the holding means to the first machining unit. Then it carries the treated coarse aluminum casting that has been treated by the first machining unit to the second machining unit. Then, at the second machining unit it holds a treated coarse aluminum casting that has been treated by the second machining unit with the holding means as well as transferring the treated coarse aluminum casting that has been treated by the first machining unit from the holding means to the second machining unit. Then it carries the treated coarse aluminum casting that has been treated by the second machining unit to a predetermined carrying-out corner. | ||||||

| 186 | Shock absorbing valve for a pneumatic tool | US11183587 | 2005-07-18 | US20050247467A1 | 2005-11-10 | Paul Kirsch |
| A pneumatic tool (20) for impacting a workpiece (22) is provided. The tool (20) comprises a casing (42) defining a chamber (48). A piston (54) is slidable within the chamber (48) along an operational axis (A). An exhaust valve (100), controlled by a pilot valve (200), slides the piston (54) by selectively introducing and releasing pressurized fluid into and out from the chamber (48). A tool bit (24) is slidable within the chamber (48) to impact the workpiece (22). Kinetic energy is transferred to the tool bit (24) from the piston (54) via an impact from the piston (54) as the piston (54) slides within the chamber (48). A shock absorbing valve (500) includes a floating collar (502) that is slidable along the casing (42) between two seal rings (504). A handle (34) is mounted to the floating collar (502). The floating collar (502) reciprocates along the casing (42) as fluid envelopes (506, 508) are exposed to atmosphere in an alternating manner through exhaust ports (530, 532) in the floating collar (502) to reduce pressure in the fluid envelopes (506, 508) thereby reducing shock to a user grasping the handle (34). | ||||||
| 187 | Self-centering trim punch | US10032738 | 2001-12-28 | US06772667B2 | 2004-08-10 | Mark Phlipot |
| Cast metal parts are created for use in making machinery. When these parts are formed, unwanted material remains in the openings of the parts. This material, called flash, must be removed. In the method of the present invention, the cast parts are placed on a platen of a trim press that has multi-part punches attached thereto that are configured to self-align with the openings in the cast part and operative to evenly remove the flash. The invention also relates to a punch that initially breaks through the flash with a stationary punch that removes a majority of the flash inside the opening of the cast part. Next, a moving or self-centering punch self-aligns to the opening in the cast part and operates to remove the remaining flash. The inventive punch may also include a mounting base for attachment of the multi-part punches to the plate or platen of the press. | ||||||
| 188 | Apparatus and method of forming battery parts | US10106613 | 2002-03-26 | US06499530B2 | 2002-12-31 | Robert W. Ratte |
| An apparatus and method for pressure casting a battery part wherein the state of molten lead is monitored so that when the molten lead enters a liquid-to-solid transformation stage, the volume of the mold available for the lead to solidify therein is quickly reduced through a volume contraction step to thereby cause the molten lead to flow into the remaining volume at the same time one maintains pressure on the molten lead. As the molten lead solidifies under the reduced volume and high pressure it produces a battery part that is substantially free of both tears and cracks. In an alternate method, the lead is allowed to solidify and at least a portion of the lead is mechanically deformed through a volume contraction step to cause cracks or tears in the battery part to be eliminated thereby providing a battery part free of cracks or tears. In another method of forming a pressure cast battery part free of cracks a molten lead under pressure is flowed into a battery part cavity and the pressure of the molten lead is increased to sufficiently high pressure so that when the molten lead solidifies it forms a battery part free of cracks and voids. | ||||||

A shut-off valve, having an open position to allow a charge of molten lead to flow into the mold cavity and a closed position to prevent molten lead from flowing out of the runner as the molten lead in mold cavity solidifies with the shut-off valve configurable to intensify the pressure of the lead in the mold cavity. | ||||||

| 200 | Lead acid battery grid casting system installation and technique | US770600 | 1977-02-22 | US4090550A | 1978-05-23 | Bela Szakacs; Frank Scrattish |
| A lead melting furnace or pot, large enough to provide molten metal for 6-18 grid casting machines, is isolated from the casting machines in a separate, remote, room or chamber. The automatically fed, electrically heated, covered and insulated furnace is positioned at a level above the inlet to the casting machines, so that the molten metal is gravity fed from one or more bottom discharge outlets whereby conventional pumps are eliminated and agitation of the molten metal in the furnace minimized. An impedance heated feed line system connects the furnace and casting machines and elevates the molten metal from the relatively low 700.degree.-800.degree. F. temperatures achieved in the furnace to the required 850.degree.-1100.degree. F. casting temperature. A specially designed exhaust hood covers each group (preferably 3) of casting machines to exhaust contaminated gases and simultaneously provide make-up air to minimize the effect on the casting room atmosphere. A scrap conveyor continuously collects excess lead trimmed from the finished grids and returns the reusable metal immediately to the furnace. | ||||||
