Abstract
Abstract A punching machine with multiple fixed work stations, comprising a series of different punches disposed one after the other along common plane of alignment and opposite which the striking hammer can be displaced along this plane to be brought above the selected punch. This machine comprises a device for setting the position provided for the article to be punched, which comprises a setting templet and a control member, one of these members being fixed and the other associated with the movable support for the article to be punched, and the fixed member of this device is mounted on the frame of the machine in such a manner as to be able to be displaced parallel to the plane of alignment of the punches. This member is coupled to the movable striking hammer, or to the means for controlling the displacement of the same, along the plane of alignment of the punches, in such a manner that the displacement of this hammer in this direction causes an identical displacement of the fixed reference member of the setting device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
214 words
A punching machine comprising a frame; a platen above said frame movable in two directions which are normal to each other; means connected to said frame and said platen for guiding the latter movable in said directions; means on said platen for holding a workpiece to be punched and a templet in fixed position and laterally spaced from each other for movement with said platen in said directions; a series of punches of different cross-sections having parallel axes located spaced from each other in a common plane substantially normal to said platen; means fixed to said frame for guiding each of said punches movable from a rest to an operating position for punching a hole in a workpiece carried by said platen; striking means movable in said common plane for alignment with a respective one of said punches and cooperating with a respective punch for moving the same from said rest to said working position; a stylus cooperating with said templet and mounted for movement in said common plane; and means for connecting said stylus with said striking means for adjusting the position of the latter in said plane in accordance with the position of said stylus, said connecting means maintaining said stylus and said striking means at a fixed distance from each other.
Claim 2
Dependent Claim
214 words
A punching machine comprising a frame; a platen above said frame movable in two directions which are normal to each other; means connected to said frame and said platen for guiding the latter movable in said directions; means on said platen for holding a workpiece to be punched and a templet in fixed position and laterally spaced from each other for movement with said platen in said directions; a series of punches of different cross-sections having parallel axes located spaced from each other in a common plane substantially normal to said platen; means fixed to said frame for guiding each of said punches movable from a rest to an operating position for punching a hole in a workpiece carried by said platen; striking means movable in said common plane for alignment with a respective one of said punches and cooperating with a respective punch for moving the same from said rest to said working position; a stylus cooperating with said templet and mounted for movement in said common plane; and means for connecting said stylus with said striking means for adjusting the position of the latter in said plane in accordance with the position of said stylus, said connecting means maintaining said stylus and said striking means at a fixed distance from each other.
Claim 3
Dependent Claim
66 words
A punching machine as defined in claim 1, wherein said striking means comprise a striking hammer, a guide block for guiding said striking hammer in said plane for alignment with one of said punches, and means cooperating with said guide block for moving the same in the direction of the axis of said one punch for moving the latter from said rest to said operating position.
Claim 4
Dependent Claim
46 words
A punching machine as defined in claim 2 wherein said block has a surface inclined to the axes of said punches and wherein said means for moving said guide block comprises a wedge movable in a direction transverse to said axes and engaging said inclined surface.
Claim 5
Dependent Claim
81 words
A punching machine as defined in claim 1, and including a block having an upper and a lower arm substantially parallel to said platen and arranged to accommodate a workpiece held by said platen between said arms, said upper arm being provided with a plurality of guide bores for guiding said punches movable between said rest and said operating positions and said lower arm being provided with bores respectively aligned with said guide bores and constituting die openings for said punches.
Claim 6
Dependent Claim
26 words
A punching machine as defined in claim 2, wherein said connecting means extend between said stylus and said striking hammer and are constituted by a rod.
Claim 7
Dependent Claim
19 words
A punching machine as defined in claim 1, wherein said common plane is parallel to one of said directions.
