摘要： PURPOSE:To improve the quality of a press product by constraining a 1st constraint point of the part where a blank holder face is corresponding to on the outer peripheral edge of a punch pressing face and 2nd constraint point where the punch pressing face comes into contact with a work initially at a specified position and making the shape of the pressing face optimum. CONSTITUTION:The outer peripheral edge part V of a work W is pinched by the supporting face 12 of a die 11 and the bland holder face 14 of a blank holder member 13. The work W is press-formed in the necessary shape by the pressing face 16 of a punch. The 1st constraint point 21 located on the visible outline J corresponding to the outer peripheral edge of the punch pressing face 16 and the 2nd constraint point 22 located at the inner part of the visible outline J are selected and the depth position of the respective constraint point 21, 22 is set. the shape of the curved face K stipulated for by a finite element method is found by constraining the constraint points 21, 22 at the depth position and a blank holder face 14a and inner push face (m) are then obtd. With this die, the quality of a press forming product can be increased and the time spent for the design manufacture of a die can be curtailed.

摘要： PURPOSE: To prevent a laser optical system from being broken by the combustion or explosion of a hydrocarbon gas in the laser carbonizing and quenching treatment using the hydrocarbon gas. CONSTITUTION: A steel member 3 is irradiated with the laser beam 10 to melt a part thereof, and the molten part is carbonized by feeding the hydrocarbon gas 11 to the laser irradiation part (a) to form a bead-shaped carbonized and quenched part. A passage 9 to feed the hydrocarbon to the laser beam irradiation part (a) or in the vicinity thereof, and a passage 8 through which the laser beam passes are provided separately to achieve the laser beam carbonizing and quenching treatment without feeding the hydrocarbon gas in the laser beam optical system. When the treatment is completed, the hydrocarbon gas left in the passage through which the laser beam passes is discharged to the carbonizing and quenching treatment part side by providing a hydrocarbon gas feeding means and an inert gas feeding means to respectively feed the hydrocarbon and an inert gas to the passage through which the laser beam passes to discharge the remained hydrocarbon gas by feeding the inert gas.

摘要： PURPOSE: To prevent the exhaust gas containing hydrocarbon gas from getting ignited/combusted by adding incombustible gas to the air flowing-in in the laser beam irradiating direction and hydrocarbon gas flowing out from laser beam irradiating part. CONSTITUTION: A steel 11 is irradiated with a laser beam 8 through a nozzle hole 71 of nozzle 7 so as to melt part of the steel 11 and a hydrocarbon gas 9 is supplied to laser irradiating part, carburization is executed to melted part. At this time, for the air flowing-in in the laser beam irradiating direction (a) and the hydrocarbon flowing out from the laser irradiated part (a), incombustible gas (CO, etc.) is added to make an exhaust gas incombustible and then to be exhausted from an exhaust path 12a. By this method, the combustible hydrocarbon gas is safely treated.
