Abstract

The invention discloses a silencer pipe joint forming die which comprises an upper die body and a lower die body. A die handle is arranged in the center of the top end of the upper die body. A male die is arranged in the center of the bottom end of the upper die body. A female die is arranged in the center of the lower die body and corresponds to the male die. Two symmetrically-distributed guide assemblies are arranged between the upper die body and the lower die body. Each guide assembly comprises a guide sleeve and a guide column which are matched and connected in a sleeved mode, wherein the guide sleeve is fixed to the upper die body, and the guide column is fixed to the lower die body. The two sides of the upper die body and the two sides of the lower die body are each provided with a lifting lug. An ejector rod is arranged in the center of the male die. The lower die body is provided with a plurality of evenly-distributed die holder foot pads. The silencer pipe joint forming die overcomes defects of a seamless pipe machining method in the prior art, is convenient to maintain, safe and reliable, and improves production efficiency. The formed products are high in sealing performance after being welded, and the enterprise production cost is lowered.

Description

A kind of muffler pipe joint mould
Technical field
The present invention 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.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of muffler pipe joint mould, this mould is easy to maintenance, safe and reliablely improves production efficiency, can ensure that high-temp waste gas is discharged safely, can reduce noise simultaneously, reduces enterprise's production cost.
Object of the present invention 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 present invention 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 present invention is described in further detail below.
