Lower edge can contact with punch table 1, and because punching portion 5 is also constantly moving downward, therefore pressing plate 51 can be in rubber cover 52
Air is extruded, and the air in rubber cover 52 is entered in escape pipe 53, is then squeezed into inside outer sleeve 211, gas
The gap entered between sliding bar 2122 and supporting table 2, with air gradually increase, just promote sliding bar 2122 towards
Polishing chamber 12 is moved, and last sliding bar 2122 is extend into the hole of stamping parts, and the hole wall of polishing 213 pairs of stamping parts of layer is beaten
Mill.
When punching portion 5 after the punching for the stamping parts that completion liquidates in vestibule 11, power part 4 drives punching portion 5 to move upwards；
Now, rubber cover 52 gradually leaves punch table 1, and rubber cover 52 restores to the original state, and the air inside outer sleeve 211 is from the row of escape pipe 53
Go out, elastic component 214 causes sliding bar 2122 to move and then set back upwards；Stamping parts after polishing is taken out of polishing chamber 12
Go out；Then the stamping parts in punching chamber 11, having completed punching is taken out, and be put into polishing chamber 12；Take new stamping parts
It is put into polishing chamber 12, repeats above-mentioned action and continue to be punched out next stamping parts and next stamping parts with holes is entered
Row polishing.
