A punching device for forming a predetermined pattern (20) on a surface near a discharge hole (11) and an intake hole (11) of a valve plate for a compressor comprises: a seating jig (100) to which the valve plate (10) is fixed; a processing pin (200) in which a pressing part (210) for pressing the valve plate (10) is formed at a distal end thereof; and a moving unit (300) which is disposed on an upper portion of the seating jig (100), horizontally moves the processing pin (200) at a constant speed while allowing the processing pin (200) to vertically reciprocate at a constant speed, so as to form the pattern (20) on the valve plate (10).
A punching device for improving surface roughness and forming a predetermined pattern (20) on a surface near a discharge hole (11) and an intake hole (11) of a valve plate for a compressor, the punching device comprising:
A pattern processing method for horizontally and vertically moving a processing pin (200) having a processing part formed at a distal end thereof so as to form a predetermined pattern (20) on a surface near a discharge hole (11) and an intake hole (11) of a valve plate (10) for a compressor, wherein the processing pin (200) vertically reciprocates at a constant speed while horizontally moving along an outer periphery of the discharge hole (11) and the intake hole (11) so as to perform punching, and as being farther from the discharge hole (11) and the intake hole (11), a vertical moving speed is identical and a horizontal moving speed of the processing pin (200) is identical or increased.
A punching pattern (20) formed on a surface near a discharge hole (11) and an intake hole (11) of a valve plate (10) of a compressor, wherein a plurality of lines (L), in which a dot (12) having a predetermined shape is formed to be spaced apart from each other at a predetermined interval along an outer periphery of the discharge hole (11) and the intake hole (11), are formed to be spaced apart from each other to become father from the discharge hole (11) and the intake hole (11), and an interval between the lines (L) becomes larger as being farther from the discharge hole (11) and the intake hole (11).
