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 ).

First claim

What is claimed is:

1 . 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 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 ).

2 . The punching device of claim 1 , further comprising: a height adjusting support ( 400 ) for adjusting a height of the moving unit ( 300 ).

3 . The punching device of claim 1 , wherein the pressing part ( 210 ) has a conic shape, a diameter of which is decreased downwardly.

4 . The punching device of claim 1 , wherein a slope angle (a) of the pressing part ( 210 ) is one of 60 degrees, 90 degrees, and 120 degrees.

5 . The punching device of claim 1 , wherein the pressing part ( 210 ) has a distal end, a sectional surface of which is hexagonal or polygonal.

6 . 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.

7 . 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 ).

8 . The punching pattern ( 20 ) of claim 7 , comprising:
a first section ( 21 ) which is formed along an outer periphery of the discharge hole ( 11 ) and the intake hole ( 11 ) and does not have the line (L) formed therein; a second section ( 22 ) which is formed on an outer side of the first section and has the plurality of lines (L) formed therein; and a third section ( 23 ) which is formed on at outer side of the second section ( 22 ) and has the plurality of lines (L) formed therein, wherein an interval between the lines (L) and an interval between the dots ( 12 ) are larger than those of the second section ( 22 ).
