发明名称 PERFORATOR
摘要 PURPOSE: A perforator is provided, in which moving inclination angle of cam slider is controlled according to operation conditions so that holes of panel processed by perforating punch are standardized per respective parts. CONSTITUTION: The perforator comprises a lower mold driver(10) an upper part of which is formed in an opened box shape, on one surface of length direction of which screw hole(11) is formed, and on the bottom surface of the inside of which guiding groove(12) having certain width and length is longitudinally formed; a lower mold cover plate(20) the front end of which rotationally is installed at the upper side of the lower mold driver(10) as the lower mold cover plate(20) is being connected to the other side part oppositely directed to one surface on which the screw hole(11) is formed by means of a hinge(21); a fluid pocket(30) which is positioned inside the lower mold driver(10) so that shape of the fluid pocket(30) is changed quite freely according to magnitude of external force as supporting the bottom surface of the lower mold cover plate(20); an angle adjusting means(40) which is installed in such a way that the angle adjusting means(40) is straight line moved along the screw hole(11), and in which one end of the angle adjusting means(40) positioned inside the lower mold driver(10) supports the bottom surface of the lower mold cover plate(20) and presses the fluid pocket(30) to adjust inclination angle of the lower mold cover plate(20); a cam slider(50) on oppositely directed both surfaces of which inclination plane(51) and punch connection surface(52) are respectively formed, and which is installed on the upper surface of the lower mold cover plate(20) with compression spring(60) interposed between the cam slider(50) and the lower mold cover plate(20); a perforating punch(70) mounted on the punch connection surface(52) of the cam slider(50) by means of a plurality of connection members; and an upper mold driver(80) for coercively slidingly moving the cam slider(50) along the inclination plane of the lower mold cover plate(20) by selectively pressing the inclination plane(51) of the cam slider(50).
