Abstract
The utility model discloses a disc spring stamping die with a centering ring groove. The disc spring stamping die with the centering ring groove comprises a lower die plate, a lower die, a positioning pin, an upper die and connection nuts. A center hole is arranged in a lower die body and a die head hole is arranged in an end face of the lower die body. A disc spring-shaped cavity with a slant-faced bottom is arranged in an end face of the bottom of the die head hole and an angle (a1) of the slant face is identical with an angle (a3) of a disc spring. A ring of bosses with arc cross sections are arranged on the slant face of the disc spring-shaped cavity. Three threaded holes and a positioning pin installation hole are arranged in the lower die body. The lower die is installed on the lower die plate through the positioning pin and the connection nuts. A die head is arranged on an upper die body and the die head is matched with the die head hole of the end face of the lower die body in a motion mode. The end portion of the die head is a slant plane. An angle (a2) of the slant plane is identical with an angle (a1) of the slant plane of the end portion of the bottom of the die head hole on the lower die body. A frustum of a cone is arranged on an end portion of the die head.
Description
Technical field
The utility model relates to a kind of punch-forming mold, particularly a kind of punch-forming mold for processing engine valve actuating mechanism valve rotating mechanism disk spring.
Background technology
Valve rotating mechanism is a significant components in the engine valve actuating mechanism, if valve produces uniformly in the course of the work, rotatablely moves slowly, can make the valve temperature even, also the carbon distribution on the conical surface and the valve stem can be wiped, like this, not only can improve the lubricating condition of valve stem but also also all very favourable for the thermal conductivity of improving valve seating and conduit.Therefore valve-face just is difficult for producing the bad phenomenon such as corrosive wear and wearing and tearing are inhomogeneous.Adopt valve rotating mechanism often can make the useful life of valve improve 2～5 times, and belong to environmentally friendly machine.
Tradition is used for the disk spring of valve rotating mechanism when work, in the process by dish → pressing → dish, because not centering, the phenomenon of center appears departing from easily, cause the inhomogeneous and serious wear of disk spring wearing and tearing, even stuck, and then cause the inefficacy of valve rotating mechanism, can not drive valve spring and valve and rotate.
Can overcome the above-mentioned deficiency of prior art with the engine valve rotating mechanism disk spring of centering annular groove.With centering annular groove engine valve rotating mechanism disk spring shown in accompanying drawing 6,7, being provided with a ring cross-section on the outer inclined-plane of disk spring 6 is the centering annular groove 6-1 of circular arc, the angle on inclined-plane is a3.During work, slide in the centering annular groove of steel ball on the valve rotating mechanism on disk spring, disk spring is played certralizing ability, avoided disk spring to depart from center and stuck phenomenon, and even wearing is consistent, has improved the service life of disk spring.
Summary of the invention
The purpose of this utility model provides a kind of processing with the punch-forming mold of the engine valve rotating mechanism disk spring of centering ring groove.
The technical solution of the utility model is: a kind of punch forming module with centering annular groove disk spring comprises lower bolster, counterdie, alignment pin, patrix and attachment screw.
Described lower mould body is provided with centre bore, and the diameter of centre bore is the same with the aperture of disk spring.The end face of lower mould body is provided with die holes, being provided with the bottom at the bottom end face of die holes is the disk spring die cavity on inclined-plane, the angle a1 on inclined-plane is the same with the angle a3 of disk spring, the inclined-plane of disk spring die cavity is provided with the boss that a ring cross-section is circular arc, and die holes, disk spring die cavity and boss are on the same axis.Also be provided with three screwed holes and an alignment pin installing hole on the lower mould body, screwed hole is evenly distributed on the lower mould body, the alignment pin installing hole be located at two screwed holes between.Counterdie is installed on the lower bolster by alignment pin and attachment screw.
The body of described patrix is provided with die head, the diameter of die head is the same with the diameter in counterdie body end face upper die head hole, adopt movingly between die head and the counterdie body end face upper die head hole, the end of die head is the inclined-plane, and bevel angle a2 is the same with the bottom end face ramp angle a1 in lower mould body upper die head hole.The end of die head is provided with a taper round platform, and taper round platform and die head are on the same axis, and the outside diameter of taper round platform is the same with the diameter in the upper heart of lower mould body hole, and adopts movingly between the upper heart of the lower mould body hole.
During punch process, the semi-finished product disk spring that processes is put into the disk spring die cavity of counterdie, and the forcing press running drives patrix and moves downward, under the effect of pressure, patrix is pressed into the semi-finished product disk spring that processes in the disk spring die cavity of counterdie fully, finishes punch forming.
The utility model compared with prior art has following features:
Centering annular groove on the disk spring is with whole disk spring punch forming, and stamping forming disk spring precision is high, the cycle is short, cost is low.
Below in conjunction with the drawings and specific embodiments detailed construction of the present utility model is further described.
