Abstract
A cold circular saw has a saw blade displaceable in a substantially vertical feeding direction and also swingable, a clamping device including at least one stationary abutment member and operative for laterally abutting against and holding a workpiece, and an adjustment element for adjusting the saw blade in its plane and in a direction which is transverse to the workpiece feeding direction and to the saw blade feeding direction, as well as relative to the stationary abutment of the clamping device.
Claims25
A cold circular saw for cutting a workpiece displaceable in a workpiece feeding direction, the cold circular saw comprising a machine support;
- a saw blade extending in a predetermined plane, said saw blade being displaceable in a substantially vertical saw blade feeding direction and also being swingable;
- means for clamping a workpiece and operative for laterally abutting against and holding the workpiece, said clamping means including at least one stationary abutment member;
- a swingable supporting arm arranged to support said saw blade and having one free end portion provided with a hinge for swinging said supporting arm;
- said supporting arm has another free end portion which is opposite to said one free end portion and further comprising a displacing element articulately connected with said other free end portion of said supporting arm and with said machine support and a carriage on which said hinge of said supporting arm is mounted, said carriage being displaceable in an adjusting direction on said plane of said saw blade and transverse to a workpiece feeding direction, relative to said machine support and said workpiece clamping means.
A cold circular saw as defined in claim 19, wherein said displacing element turning during the displacement of said saw blade, said switching means further including curved actuating member provided on said machine support, said actuating member being connected with said displacing element and movable relative to said end switch so as to actuate the latter, said end switch being operative for adjusting the turning of the displacement element so as to provide a minimum passage of said saw blade outwardly beyond the sawn workpiece.
