<p>The present invention relates to a cam shaft type press apparatus capable of selectively operating a press, which comprises: a press main body (10) composed of a lower plate (11) and an upper plate (12) which have a plate shape and are placed in the upper and the lower parts thereof respectively, and a pair of side plates (13) which is connected to between the lower plate (11) and the upper plate (12); a pressurization operating unit (20) composed of multiple moving rods (21) which penetrate the upper plate (12) and vertically move, a press mold (22) which is connected to the upper part of the moving rod (21) and pressurizes the top surface of a workpiece (P), and a pressurization base unit (23) which is connected to the lower part of the moving rod (21); and a pressurization driving unit (30) composed of a driving shaft (31) which is placed in the upper part of the pressurization base unit (23) and is connected to the pair of side plates (13), a driving motor (M) which is connected to one end unit of the driving shaft (31) in order to transmits driving force, and multiple operating cams (32) which are eccentrically formed on the outer circumference of the inner side of the driving shaft (31). In addition, the cam shaft type press apparatus includes a cylinder which horizontally moves a pressure transmitting unit in contact with the eccentrically rotating driving cam, in order to selectively operate a mold to be vertically moved among multiple molds. A pressurization slope surface is formed on the top surface of the pressure transmitting unit where the driving cam in contact with the driving cam in order to easily change the height of the vertical movement of the mold.</p> |
