Combination punch press and laser machine
First Claim
1. A combination punch press and laser machine, comprising:
- at least one pair of coacting punch and die mounted to one frame;
a worktable;
clamping means for holding and moving a worksheet on said worktable;
an other frame positioned adjacent said one frame and having a cantilever member extending over said worktable;
a laser cutting system mounted to said other frame;
a laser cutting head of said laser cutting system mounted to said cantilever member so as to be in alignment with and superposed over a particular location on said worktable; and
cushioning means with the amount of cushion provided thereby being regulated for supporting said other frame, preventing uneven loading conditions of said other frame, and isolating said other frame from said one frame to thereby ensure that said laser cutting head remains in alignment with said particular location irrespective of the amount of impact and critical vibrations occurring at said one frame resulting from at least the fabrication of said worksheet by said pair of punch and die at said one frame.

Abstract
A combination punch press and laser machine has its punch press system and worktable mounted to one frame while its laser system mounted to another frame. The two frames are not in contact with each other, but are positioned such that a cantilever member of the frame whereon the laser system is mounted extends over the worktable so that the laser cutting head which is mounted to the end of the cantilever member superposes over a particular location of the worktable whereat the cutting of the worksheet by the laser beam is to be effected. This particular laser cutting location is positioned relative to the location of the worktable whereat the punching of the worksheet is to be effected by the pair of coacting upper tool and lower die of the punch press system. To prevent vibrations, be it resulting from impacts of the tool and die to the worksheet at the punching station or environmental vibrations, from affecting the accuracy of the positioning of the laser cutting head and damaging the laser cutting system, the frame on which the laser system is mounted is isolated from the floor by a number of rubber air springs which pressure is adjustably controlled by regulators. A number of safety supports that work in conjunction with the air springs prevent any collapse of the laser system frame in the unlikely event that the appropriate pressure is not maintained in the air pressure springs.

10. A method of isolating a laser cutting system from a punching system in a combination laser and punch press machine, comprising the steps of:
-
a) mounting at least one pair of coacting punch and die to one frame; b) movably coupling clamping means to a worktable, said clamping means holding and moving a worksheet on said worktable; c) positioning an other frame adjacent said one frame, said other frame having a cantilever member extending over said worktable; d) mounting a laser cutting system to said other frame; e) mounting a laser cutting head of said laser cutting system to said cantilever member to be in alignment with and superposed over a particular location on said worktable; and f) providing cushioning means with the amount of cushion provided thereby being regulated to the underside of said other frame for supporting said other frame and preventing uneven loading of said other frame so as to ensure that said laser cutting head remains in alignment with said particular location irrespective of the amount of impact and vibrations occurring at said one frame. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
