Abstract:
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).
