The reference numbers illustrate: 1. a shell punching cylinder; 2. an exhaust pipe; 3. a sound-deadening tube; 4. a control air valve; 5. silencing cotton; 6. an upper cover; 7. the lower cavity.

Detailed Description

Please refer to fig. 1-2, the utility model discloses a disappointing amortization structure of cylinder of towards shell device, including hush pipe 3, control air valve 4, blast pipe 2 and be used for towards shell cylinder 1 for towards shell device provides power, it is equipped with disappointing mouthful on the shell cylinder 1 to dash, disappointing mouthful is connected with the air inlet of control air valve 4 through blast pipe 2, hush pipe 3's both ends are equipped with inlet port and exhaust hole respectively, the gas outlet of control air valve 4 is connected with hush pipe 3's inlet port through blast pipe 2, hush pipe 3 intussuseption is filled with amortization cotton 5.

Compare in prior art, the gas that dashes the mouth of losing air of shell cylinder 1 among the embodiment gets into through blast pipe 2 and gets into by air inlet entering control pneumatic valve 4, carry out transient storage by the control pneumatic valve, again by control pneumatic valve 4 control gas pass through the inlet port that the blast pipe got into the hush pipe by the gas outlet, gas in the hush pipe carries out amortization by the amortization cotton, later discharge by the venthole again, and then avoid being used for the cylinder of punching press directly to the noise pollution that the gas brought in the air of discharging, improve operational environment, effectively protect staff's in the workshop physical and mental health.

Specifically, the silencing tube 3 comprises a lower cavity 7 and an upper cover 6 which is covered with the lower cavity 7, wherein the lower cavity 7 is a cylinder, and the upper cover 6 is screwed with the lower cavity.

By adopting the scheme, the upper cover 6 and the lower cavity 7 are mutually covered to form the silencing tube 3 in the embodiment, so that the silencing cotton 5 in the silencing tube 3 can be conveniently replaced, the maintenance cost is reduced, the cylindrical lower cavity 7 is adopted, the carrying is more convenient, and the occupied space is smaller than that of silencing tubes in other shapes while the same purpose is achieved.

Specifically, the silencing tube 3 is made of plastic.

Adopt above-mentioned scheme, the material of muffler pipe 3 is the plastics material in this embodiment, and the manufacturing and use of being convenient for reduces manufacturing cost.

Specifically, the upper surface of the upper cover 6 is provided with an air inlet, and the lower end of the lower cavity 7 is provided with an air outlet.

Adopt above-mentioned scheme, locate the upper surface of upper cover 6 with the inlet port in this embodiment, locate cavity 7's lower extreme down with the venthole, furthest's improvement inlet port and venthole between the distance is favorable to gas to carry out amortization through the amortization cotton in the muffler, improves the noise cancelling effect.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
