Abstract
The torch of a machine for progressive contour bevel cutting of flat plates is mounted for controlled positioning and movement on an arcuate sector, the radius of which has a center lying in the horizontal plane of the plate. The torch is mounted for movement between adjustable stops which delineate two torch angles for cutting. A device is provided for substantially instantaneously moving the torch along the sector from adjacent one stop to the other stop. In the embodiment disclosed herein, the said device comprises a fluid-operated piston connected to the torch.
Claims7
In a device for progressively cutting a flat workpiece, the combination comprising:
- (a) a frame,
- (b) an arcuate sector mounted on said frame,
- (c) a cutting torch connected to said sector and movable arcuately relative to said frame,
- (d) a plurality of arcuately spaced stop members disposed on said frame and in the path of arcuate movement of said torch and engageable thereby, said stop members defining a plurality of spaced fixed descrete arcuate positions of said torch with said positions being translatable into the respective angles of cut on the workpiece,
- (e) and fluid pressure actuated means to substantially instantaneously move said torch arcuately between said spaced discrete positions to provide a resultant instant change of cutting angle on the workpiece as said torch cuts the workpiece.
In a device for progressively cutting a flat workpiece, the combination comprising:
- (a) a frame,
- (b) an arcuate sector mounted on said frame and with said sector having a radius, the center of which is disposed in the plane of the workpiece,
- (c) a cutting torch,
- (d) means suspending said cutting torch from said sector so that said torch is arcuately movable relative to said frame,
- (e) means disposed on said frame and defining a plurality of spaced fixed discrete arcuate positions of said torch and with said positions being translatable into the respective angles of cut on the workpiece,
- (f) said last-named means (e) comprising a plurality of arcuately spaced stop members disposed in the path of arcuate movement of said torch and engageable thereby,
- (g) said stop members being adjustable to selectively vary the angular engaged stop positions of said torch and the resultant angles of cut,
- (h) and means to substantially instantaneously move said torch arcuately between said spaced discrete positions to provide a resultant instant change of cutting angle on the workpiece as said torch cuts the workpiece,
- (i) said last-named means (h) comprising:
- a fluid cylinder having a shiftable ram connected to said torch, and means to shift said ram substantially instantaneously.
