High-impact portable riveting apparatus
Abstract
Abstract A HIGH-IMPACT TOOL IS DISCLOSED AS PART OF A RAM COMPONENT OF AN ELECTRO-MECHANICAL GUN, AS SHOWN IN FIG. 1, WHICH CONVERTS A RAPIDLY CHANGING ELECTRIC CURRENT PASSING THROUGH ITS COIL INTO A MECHANICAL FORCE ACTING BETWEEN A CONDUCTOR PLATE ON THE RAM AND THE COIL TO PROPEL THE RAM AND ITS FORMING SURFACE AGAINST A WORKPIECE TO FORM IT. A PAIR OF PORTABLE ELECTRO-MECHANICAL RIVERTING FUNS, AS SHOWN IN FIGS. 3-7, IS DESCRIBED ALONG WITH AN ELECTRICAL SYSTEM, SHOWN IN FIG. 8, WHICH INTERLOCKS THEIR OPERATION TO INSURE A SIMULTANEOUS RAM IMPACT ON EACH END OF THE RIVET. THE POWER SUPPLY, FOR OPERATOR SAFETY, IS ISOLATED FROM GROUND AS IT DISCHARGES THROUGH THE COILS. A SYSTEM, SHOWN IN FIGS. 5-7, FOR PROPER GUN ALIGNMENT IS DISCLOSED WHEREIN INCREASED BACK-PRESSURE OF FLUID OR GAS OUTLETS, BLOCKED BY PROPER GUN POSITIONING AGAINST THE WORKPIECE, OPERATES CONTROL SWITCHES PERMITTING FIRING OF THE GUNS.
