Description
Technical field
The utility model relates to auto parts and components mould field, a kind of muffler pipe joint of specific design mould.
Background technology
Automotive muffler hinders sound transmission and allows special equipment that air-flow passes through, control air flow power noise, thus reduce the exhaust noise of engine, and high-temp waste gas can be discharged safely and effectively.To be exactly its automobile exhaust pipe be its principle is made up of the pipeline that two length is different, and these two pipelines first separately cross again.Silencer is as a part for discharge duct, should ensure that its exhaust is unimpeded, resistance is little and sufficient intensity, not damage when ensureing that 500 DEG C ~ 700 DEG C of high-temperature exhaust airs are stood in the distance travelled inherence of automotive regulations, do not lose soundproof effect, therefore, the necessary level and smooth no concave-convex of muffler tail pipe joint inner surface, pipe joint place must seal and produce without gas leak phenomenon.At present, mainly directly utilize ready-made seamless pipe through machined finished product by traditional handicraft processing tube jointing method, although the product that this method processes also has certain soundproof effect when synthesizing target product product, but the pipe joint processed like this is often because Technology design is unreasonable, cause interior tubular smooth round and smooth degree inadequate, easily cause sound and air-flow communication portion smooth and increase the exhaust noise of engine, high-temp waste gas can not be discharged safely and effectively, not only reduce the service life of product, have impact on the normal traveling of automobile, also create production efficiency low, indirectly add enterprise's production cost.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of muffler pipe joint mould, and this mould is easy to maintenance, safe and reliablely improve production efficiency, can ensure that high-temp waste gas is discharged safely, can noise be reduced simultaneously, reduce enterprise's production cost.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of muffler pipe joint mould, comprise mould body and lower mould body, the center, top of described upper mould body is provided with die shank, bottom center place is provided with punch, the center of described lower mould body is provided with die, described die and punch are mutually corresponding, two groups of symmetrical guidance sets are provided with between upper mould body and lower mould body, often organize guide pin bushing and guide pillar that guidance set comprises socket cooperation, the diameter of guide pillar is less than the internal diameter of guide pin bushing, described guide pin bushing is fixed on mould body, described guide pillar is fixed on lower mould body, hanger is provided with in the both sides of upper mould body and lower mould body, described hanger is stepped cylindrical structure, the center of described punch is provided with ejector beam, die shank is stretched out in the upper end of ejector beam, described ejector beam is in T shape, described lower mould body is provided with multiple equally distributed die holder feet.
Further, described die shank by soket head cap screw and upper mould body fastening.
Further, described punch adopts soket head cap screw and upper mould body fastening, described die employing soket head cap screw and lower mould body fastening.
A kind of muffler pipe joint of the utility model mould, processed by mould punching form, solve in prior art the deficiency adopting seamless pipe machine-tooled method, this mould is easy to maintenance, safe and reliable simultaneously, improve production efficiency, after product seam after shaping, sealing is strong, and high life, can ensure that high-temp waste gas is discharged safely, can noise be reduced simultaneously, reduce enterprise's production cost.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of muffler pipe joint of the utility model mould;
Fig. 2 is the left view of Fig. 1.
In figure: the upper mould body of 1-; Mould body under 2-; 3-die shank; 4-punch; 5-die; 6-guide pin bushing; 7-guide pillar; 8-hanger; 9-ejector beam; 10-die holder feet.
Detailed description of the invention
As shown in Figure 1-2, a kind of muffler pipe joint mould described in the utility model embodiment, comprise mould body 1 and lower mould body 2, the center, top of upper mould body 1 is provided with die shank 3, bottom center place is provided with punch 4, the center of lower mould body 2 is provided with die 5, die 5 is mutually corresponding with punch 4, two groups of symmetrical guidance sets are provided with between upper mould body 1 and lower mould body 2, often organize guide pin bushing 6 and guide pillar 7 that guidance set comprises socket cooperation, the diameter of guide pillar 7 is less than the internal diameter of guide pin bushing 6, guide pillar 7 can be plugged in guide pin bushing 6, guide pin bushing 6 is fixed on mould body 1, guide pillar 7 is fixed on lower mould body 2, hanger 8 is provided with in the both sides of upper mould body 1 and lower mould body 2, hanger 8 is stepped cylindrical structure, the center of punch 4 is provided with ejector beam 9, be convenient to the finished product after roof fall processing, the upper end of ejector beam 9 is stretched out die shank 3 and end is provided with positive stop lug boss, ejector beam 9 is overall in T shape, lower mould body 2 is provided with multiple equally distributed die holder feet 10, mainly play certain carrying effect at upper mould body 1 with during lower mould body 2 Operating In Persistent Current Mode, the fracture that the antifatigue degree avoiding lower mould body 2 to cause because external force is excessive occurs not, improve the mold use life-span.
One preferred embodiment, die shank 3 by soket head cap screw and upper mould body 1 fastening, punch 4 adopt soket head cap screw and upper mould body 1 fastening, die 5 adopt soket head cap screw and lower mould body 3 fastening, die shank 3, upper mould body 1 and lower mould body 2 adopt above-mentioned fixed form, be convenient to mounting or dismounting and maintenance, cost-saving while guarantee instructions for use.
