Abstract
The utility model discloses a simple press machine exhaust silencer which comprises an inner pipe and an outer pipe sleeved on the inner pipe. An annular exhaust cavity is formed between the inner pipe and the outer pipe, a sealing cover plate with a central hole is arranged at one end of the outer pipe, one end of the inner pipe is sealed while the other end of the inner pipe is open, the open end of the inner pipe extends out of the outer pipe from the central hole of the sealing cover plate, a plurality of through holes are formed in the side wall of the inner pipe positioned inside the outer pipe, the open end of the inner pipe is connected with a bent joint, a cushion collar is arranged at the other end of the outer pipe, and a plurality of exhaust holes are formed in the cushion collar. Therefore, the simple press machine exhaust silencer has the advantages that exhaust noise of a press machine is effectively reduced and weakened, so that noise pollution of a working environment is reduced, and a fine operating environment is provided for staff.
Description
Technical field
The utility model relates to a kind of gas damping technical field, relates in particular to the simple and easy silencer of a kind of press machine exhaust.
Background technique
Cold stamping for automobile industry, pressure mechanism, very large from the bivalve noise that the pressurized air of producing emits in punching production process, environmental pollution is very large, operator works for a long time in being full of the environment of noise pollution, be more prone to tired, vexed gas is hot-tempered, have a strong impact on work mood and mood, of long duration also can cause the generation of occupation disease, working environment noise great Ye does not meet human factor engineering's requirement simultaneously, should reduce as much as possible press machine exhaust noise, and at present a lot of muffling device complex structures, cost is very high, be difficult to promote the popularization use.
Chinese patent notice of authorization number: CN202348396U, July 25 2012 notice of authorization day, a kind of outlet pipe baffler is disclosed, comprise upper shell and with the lower shell body of upper shell brazing, on lower shell body, offer air outlet, air outlet and the flow-guiding mouth of lower shell body are bolted, and are provided with outlet pipe on flow-guiding mouth, are provided with dismountable fire extinguishing net between flow-guiding mouth and air outlet.The outlet pipe baffler of this kind of structure arranges outlet pipe at air outlet place, protected machine when controlling the direction that waste gas discharges.Its deficiency is that this kind of outlet pipe baffler erasure effect is poor, is not suitable for being used on press machine.
Model utility content
The utility model for the gas noise that overcomes press machine outlet pipe of the prior art and discharge large, affect the deficiency of employee's normal operation, a kind of noise that can effectively slow down, weaken press machine exhaust is provided, thereby has reduced the simple and easy silencer of press machine exhaust that ambient noise pollutes.
To achieve these goals, the utility model adopts following technological scheme:
The simple and easy silencer of a kind of press machine exhaust, it is characterized in that, comprise inner tube and sheathed outer tube on inner pipe, between described inner and outer tubes, be provided with annular row air cavity, one end of described outer tube is provided with the sealed cover with center hole, one end sealing the other end opening of inner tube, the opening end of inner tube stretches out outer tube from the central hole of sealed cover, and the sidewall that described inner tube is positioned at outer tube inside is provided with some through holes.The opening end of the inner tube of this kind of silencer is connected on press machine outlet pipe, the gas that outlet pipe is discharged enters after inner tube, while passing through the through hole on inner tube sidewall, there is resonant silencing, thereby weaken, reduced gas noise, also can cushion the flow velocity that weakens air-flow simultaneously, gas enters in annular row air cavity from through hole, finally from one end of outer end, discharge, processing through this kind of silencer, the gas noise that press machine outlet pipe is discharged has reduced significantly, thereby reduce the noise pollution of environment, for operator provide a working environment relatively preferably.
As preferably, the other end of described outer tube is provided with cushion collar, and cushion collar is provided with some exhaust ports, between described cushion collar and outer tube, is threaded.Because the gas velocity that press machine outlet pipe is discharged is fast, although alleviated a part during through inner tube, the gas of then discharging from one end of outer tube is still very anxious, therefore cushion collar is set to gas secondary buffer, exhaust port plays peptizaiton to gas, make the gas uniform of discharging, soft, noise is also little.
As preferably, the opening end of inner tube is connected with elbow connection.When press machine outlet pipe Exhaust Gas, while first entering elbow connection, change gas direction, make the kinetic energy rejection of gas, play buffer gas sound deadening.
As preferably, between the central hole of described sealed cover and the outer wall of described inner tube, be welded to connect.The join strength being welded to connect is large, passes through welded seal, good sealing effect between the center hole of sealed cover and the outer wall of inner tube simultaneously.
Therefore, the utlity model has effectively the noise that slows down, weakens press machine exhaust, thereby lower the noise pollution of working environment, for employee provides the beneficial effect of a good operating environment.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: inner tube 1 outer tube 2 annular row air cavity 3 sealed cover 4 through hole 5 cushion collar 6 exhaust port 7 elbow connections 8.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
The simple and easy silencer of a kind of press machine exhaust as shown in Figure 1, comprise inner tube 1 and sheathed outer tube 2 on inner pipe, between inner tube 1 and outer tube 2, be provided with annular row air cavity 3, the upper end of outer tube 2 is provided with the sealed cover 4 with center hole, the lower end closed upper end open of inner tube 1, the opening end of inner tube 1 stretches out outer tube 2 from the central hole of sealed cover 4, the opening end of inner tube 1 is connected with elbow connection 8, the other end of elbow connection 8 is connected with press machine outlet pipe, between the outer wall of the central hole of sealed cover 4 and inner tube 1, be welded to connect, the sidewall (being that sealed cover is to the sidewall between inner tube closed end) that inner tube 1 is positioned at outer tube 2 inside is provided with some through holes 5, mutual dislocation between adjacent two row through holes, thereby it is more even that gas is entered, the lower end of outer tube 2 is provided with cushion collar 6, between cushion collar 6 and outer tube 2, be threaded, cushion collar 6 is provided with some exhaust ports 7, between cushion collar 6 and the closed end of inner tube, be provided with exhaust clearance.When the gas at press machine outlet pipe place passes through elbow connection, direction changes, and gas kinetic energy rejection, is cushioned for the first time; Then gas enters inner tube from the other end of elbow connection, from the pupil of inner tube sidewall, goes out to enter in annular row air cavity, and the direction of gas changes again, kinetic energy rejection, resonant silencing while simultaneously passing through through hole, reducing noise; The exhaust port that gas in last annular row air cavity puts from buffering is discharged to the external world, and gas direction changes again, kinetic energy rejection, and gas flow rate slows down, and gas is discharged also very even, and overall noise reduces significantly.Therefore, the utlity model has effectively the noise that slows down, weakens press machine exhaust, thereby lower the noise pollution of working environment, for employee provides the beneficial effect of a good operating environment.
