Abstract
653,660. Punching; metal-sheet feeds. HALLER, J. April 27, 1948, No. 11513. [Class 83 (iv)] A step-by-step feeding device for feeding sheet-metal 81 to a cutting, punching, or stamping machine 10 comprises means for moving a work-support 29 towards and away from a stationary support 26, and a pressurefluid distributer synchronized with the movement of the support 29 for supplying pressurefluid alternately to a fluid-actuated workclamp 11, 12 mounted adjacent each support so as to clamp the work-piece against the respective support. The work-piece 81 is operated upon by a punch 16 and die 20 mounted on a base 14 which also supports by means of bolts 22 a pair of rails 24 between which the movablesupport 29 is slidably received in V-recesses. The support 29 is reciprocated by a doubleacting ram 34, which may have an adjustable stroke, and cylinder 36 connected by pressurefluid pipes 41, 42 to a cylinder 13 and doubleheaded piston 48 forming the distributer. The head of a lever 53 provided with projections 55, 56 and stroke-adjusting stop-screws 57, 58 to co-operate with a projection 59 on a lever 60. The latter is attached to a bracket 63 on the press 10 by a pin 61 bearing in a slot 62 in the bracket so that as the press is fed downwardly the lever 60 is operated to actuate the piston 48. As the piston is moved to the right, pressure-fluid in the pipe 42 causes the ram 34 and support 29 to move to the right and pressure-fluid to pass along a branch pipe 68 into the clamp 11 mounted on the support 26 which extends between the rails 24. The clamp 11 and the clamp 12, which is attached to the movable support 29, each comprise a block 65 having a wedge-shaped recess 78 housing a roller 76. Pressure-fluid acting behind one or more spring-pressed pistons which bear on the roller 76 and are housed in the block 65, forces the roller 76 against the inclined wall of the recess 78 and into binding engagement with the work-piece 81. During the downward movement of the press the workpiece is held stationary by the clamp 11 as the support 29 and clamp 12, which has been exhausted of pressure-fluid by a flexible pipe 69 connected to the pipe 41, are moved to the right. As the punch is raised from the die 20, the piston 48 is moved to the left to force pressure-fluid into the pipes 41, 69 and withdraw it from the pipes 42, 68 in order that the clamp 12 may grip the work-piece 81 and feed it towards the press, the gripping pressure of the stationary clamp 11 being released by suction in the pipe 68. The work-piece 81 is guided between adjustable rollers 84 which are mounted in T -slots 88 adjacent the cylinder 36.
