摘要： When a sheet metal is sandwiched between a punch held by a punch holder and a die held by a die holder to bend the sheet metal at a set bending angle by moving the punch toward the die, a stroke calculation unit calculates a stroke of the punch for bending the sheet metal at the bending angle in consideration of a spring back amount of the bent sheet metal. A bending load calculation unit calculates a bending load required to bend the sheet metal at the bending angle. A punch deflection amount calculation unit calculates a punch deflection amount according to the bending load. A punch holder deflection amount calculation unit calculates a punch holder deflection amount according to the bending load. A depth value calculation unit calculates a depth value by adding at least the punch deflection amount and the punch holder deflection amount to the stroke.

摘要： A breakage prevention mechanism is configured to prevent deformation or breakage of a crossbar and transfer the work even in the condition where a pair of left and right arm supporting the both end of the cross bar is displaced beyond assumption. The breakage prevention mechanism is equipped with a pair of arms which is synchronized and moves approximately parallel, and a crossbar bridged between the top end of the arms. Both end of the crossbar and the arm are connected pivotably around two axis. Both end of the crossbar are configured to be slidable against the arm in X axis direction. The plunger is placed between both end of the crossbar and arm, in which protects the crossbar by restraining the pivoting and the sliding of both in the normal condition and releasing the restraint when the unintended force is given.

摘要： A safety device for a machine, in which machine a first machine part having a leading edge performs a working movement towards a second machine part, comprises a plurality of optical safety barriers and an evaluation unit. The optical safety barriers move in the working movement simultaneously with the first machine part in such a manner that the safety barriers move in advance of the leading edge at various spaced dispositions. The optical safety barriers span a protective field that has a two-dimensional cross section. The evaluation unit is designed for generating a stop signal to stop the first machine part in dependence upon the optical safety barriers. Towards the end of the working movement, the optical safety barriers are held substantially stationary in the region of the second machine part. The optical safety barriers are deactivated one following the other before they are interrupted by the first machine part.
