Background technology
Along with economic fast development, people's living standard constantly improves, and automobile use amount is also increasing.Automobile is when being convenient for people to daily life, and the noise producing in its exhaust process also becomes the Main Noise Sources in now noise pollution.The noise pollution producing in order to reduce automobile, is all provided with silencer on automobile now, so the output of silencer increases severely.
For the ease of cored, the silencing pot of auto car rear silencer comprises upper and lower two-layer housing, and the mode by pressing after cored completes makes upper and lower two-layer housing crimping complete the sealing of shell rim.Now when the silencing pot of pressing auto car rear silencer, on exert pressure mould and lower pressure-bearing mould be separately fixed on a connecting plate, the connecting plate location of fixing lower pressure-bearing mould, the connecting plate of mould of exerting pressure on fixing is connected with power-driven mechanism, lower floor's housing of silencing pot is placed on lower pressure-bearing mould and by lower pressure-bearing mould and positions, the upper strata housing of silencing pot is placed on its lower floor's housing, by the mould of exerting pressure on driving, make the upper and lower two-layer housing interlock crimping of silencing pot again, and then complete the connection of silencing pot housing.The silencing pot of auto car rear silencer is being carried out in the process of pressing now, when the mould of exerting pressure on it contacts with lower pressure-bearing mould, interaction force is between the two larger, this just easily cause exerting pressure mould and lower pressure-bearing mould damage, and it is high to change die cost, and can expend a large amount of time and efforts.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art; a kind of active force of exerting pressure between mould and lower pressure-bearing mould on can cushion pressing auto car rear silencer housing time is provided, and then the pressure buffer device in the auto car rear silencer housing diel that can protect mould.
Object of the present invention is achieved through the following technical solutions: the pressure buffer device in the diel of auto car rear silencer housing, comprise positioning seat, lower positioning seat and cylindric upper plunger, described lower positioning seat is arranged on positioning seat below, the upper surface of lower reservation is provided with positioning pipe, the lower surface of upper positioning seat is provided with the tube connector corresponding with positioning pipe position, tube connector and positioning pipe are pipe, the upper end of described upper plunger embeds in tube connector and with tube connector and forms interference fit, the lower end of upper plunger is arranged with cylindric drift, the lateral wall of drift forms a plurality of granular projections, drift is corresponding with positioning pipe position, and the radius of drift cross section is less than the radius of positioning pipe circular open, on described upper plunger, be wound with the spring that two ends act on respectively tube connector and drift.
Tube connector of the present invention and upper positioning seat and positioning pipe and lower positioning seat all can independently exist, mode by welding connects again, in order to strengthen the bonding strength between tube connector and upper positioning seat and positioning pipe and lower positioning seat, and be convenient to manufacture, as preferably, described tube connector and upper positioning seat become one, and described positioning pipe and lower positioning seat become one.
Described drift adopts carbide alloy to make.
Compared with prior art, the present invention has following beneficial effect: (1) the present invention includes positioning seat, lower positioning seat and upper plunger, wherein, the upper surface of lower reservation is provided with positioning pipe, the lower surface of upper positioning seat is provided with the tube connector corresponding with positioning pipe position, the upper end of upper plunger embeds in tube connector, the lower end of upper plunger is provided with the drift being set on upper plunger, drift is corresponding with positioning pipe position, on upper plunger, be wound with the spring that two ends act on respectively tube connector and drift, overall structure of the present invention is simple, be convenient to realize, and when the present invention applies, above positioning seat is connected on the connecting plate of fixing the mould of exerting pressure, lower positioning seat is connected on the connecting plate of fixing lower pressure-bearing mould, when on exert pressure mould during near lower pressure-bearing mould, drift of the present invention embeds in positioning pipe, and the active force of exerting pressure between mould and lower pressure-bearing mould in buffering under the effect of spring, and then the active force of exerting pressure between mould and lower pressure-bearing mould is declined gradually, and then can effectively protect exert pressure mould and lower pressure-bearing mould.
(2) in the present invention, the radius of drift cross section is less than the radius of positioning pipe circular open, the lateral wall of drift forms a plurality of granular projections, the present invention is by the protruding role of graininess, be convenient in undershoot process gas in positioning pipe and leak by the gap between projection, and can avoid drift to be close to positioning pipe inwall and affect and drift is come off from upper plunger.
