Abstract
The utility model discloses a precision punching die for the upper shell of the air intake and exhaust manifold of the engine of an automobile, which comprises an upper fixed plate arranged on a top plate and a lower fixed plate arranged on the bottom plate, wherein the lower end face of the upper fixed plate has a male die matched with the upper surface of the upper shell; a plurality of guide posts are fixed on the upper fixed plate at the edge of the male die; and a female die matched with the male die is fixed in a groove in the lower fixed plate, an insert matched with the lower surface of the upper shell is arranged on the female die, and a plurality of guide holes matched with the plurality of guide posts are formed on the lower fixed plate on the outer side of the female die. The manifold upper shell manufactured by the punching die delivers low gas flowability due to lower thermal stability and welding performance; and the manifold upper shell is susceptible to produce internal defects, which facilitates the realization of adopting tightly coupled catalyst device on the entire front drive transverse engine.
Description
Technical field:
The utility model relates to mould applications, relates in particular to a kind of automobile engine intake and exhaust manifold upper shell precise punching die.
Background technology:
In the market, engine for automobile air inlet-outlet pipe major part all cylinder iron material cast out.Though casting can be made complicated shape; But relatively heavier, thermostable type and weldability are poor slightly, and inside is smooth inadequately, causes gas fluidity bad; Be easy to generate internal flaw; Adopt the cast type exhaust manifold to reach state III discharging and have no problem; When reaching state IV,, adopt the casting exhaust manifold to be unfavorable for being implemented in forerunner's transverse engine simultaneously and on complete machine, adopt the close coupling catalyst converter because its thermal conductivity and stainless exhaust manifold are far short of what is expected.
Automobile engine intake and exhaust manifold precise punch forming method relates to a kind of cast moulding manifold and changes the punching type manifold into; Be specifically related to a kind of selecting for use of automobile punching type manifold upper and lower casing material that be used for; The punching Technology Analysis of sheet material, the selecting for use of diel structure Design and mold materials.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of automobile engine intake and exhaust manifold upper shell precise punching die, has improved the overall performance of engine breathing manifold upper shell.
The technical scheme of the utility model is following:
Automobile engine intake and exhaust manifold upper shell precise punching die; Comprise the upper and lower fixing plate that is installed on top board, the base plate; It is characterized in that: the upper mounted plate lower surface is equipped with the punch that matches with the upper shell upper surface, is positioned at the punch edge on the upper mounted plate and is fixed with several guide pillars; Be fixed with the die that matches with punch in the groove of described bottom plate, die is provided with the mold insert that matches with the upper shell lower surface, is positioned at the die outside on the described bottom plate and has the pilot hole that matches with described several guide pillars.
Described automobile engine intake and exhaust manifold upper shell precise punching die, it is characterized in that: described top board upper surface is fixed with die shank.
Described automobile engine intake and exhaust manifold upper shell precise punching die, it is characterized in that: described base plate lower surface is fixed with the cushion pad of polyurethane material.
The utility model has the advantages that:
Manifold upper shell thermostable type and weldability that the utility model is made are poor slightly, and inside is smooth inadequately, causes gas fluidity bad; Be easy to generate internal flaw, help being implemented in forerunner's transverse engine and on complete machine, adopt the close coupling catalyst converter.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Automobile engine intake and exhaust manifold upper shell precise punching die; Comprise the upper and lower fixing plate 3,4 that is installed on top board 1, the base plate 2; Upper mounted plate 3 lower surfaces are equipped with the punch 5 that matches with the upper shell upper surface, are positioned at the punch edge on the upper mounted plate 3 and are fixed with several guide pillars 6; Be fixed with the die 7 that matches with punch in the groove of bottom plate 4, die 7 is provided with the mold insert 8 that matches with the upper shell lower surface, is positioned at the die outside on the bottom plate 4 and has the pilot hole 9 that matches with several guide pillars 6.
The material of manifold upper shell adopts the SUS441 material, gas shielded arc welding, and row's temperature reaches about 900 ℃; Soldering reliability is also no problem; After 500 hours stand reliability tests, cracking phenomena can not appear, and the smooth degree that can increase inwall reduces and gas between friction; Improve gas flow speed, make discharging can satisfy state IV laws and regulations requirement.
The utility model material uses SKD11, and mould adopts vacuum hardening, and hardness reaches: 55-61HRC; The surface is carried out TD again and is handled; To increase mold surface finish, abrasion resistance, avoid the long-pending knurl of stainless steel to stick to working portion of die, influence product appearance, cause the product problem that ftractures when serious.
