Abstract
512,631. Metal-working presses. GLASNER, R. W. March 9, 1938, No. 7327. [Class 83 (iv)] Cupping.-A double acting press has the driving mechanism for both the top and bottom dies located in a base chamber 46 and comprises' a motor driven shaft 28 actuating both mechanisms, the bottom slide 25 being driven by a pair of eccentrics 22 through gears 19, 29, and the top die actuated by connecting rods 51 driven through cranks and toggles 57, 58 operated by eccentrics 62, 64 and a shaft 61 carrying gear wheels 66 driven by pinion 67 on the shaft 28. The driven shaft 28 is rotated in. one direction through a clutch 33 driven by belt. 32 coupled to the driving motor 31. The dies. operate with a comparatively short stroke in relation to the depth of the draw. The stroke position of the top die can be altered by the screws 41. The work is placed on the work holder 15 which by means of fluid-pressurepistons 26b in the lower slide and fluid valve 26d hold its edges but allowing it to slip during cupping. An ejector 68 actuated by fluid pressure cylinders 70 is also provided. The chamber 46 for the mechanism acts as an oil chamber for the lower working parts.
