Abstract
The utility model discloses an inner ball cage cavity cold-extrusion mold which comprises an upper mold plate, a lower mold plate and a lower mold base, wherein the lower mode base is fixedly installed on the lower mold plate, the cold-extrusion mold comprises a concave mold, and an inner embracing mold and an outer embracing mold are respectively arranged around the concave mold; screw rods are respectively and fixedly installed on both sides of the lower mold base, a radial step hole is arranged on the side wall of the lower mold base, a pawl is arranged in the step hole, and the front end of the pawl stretches to a lower port of the concave mold; and the cold-extrusion mold also comprises a spring, wherein one end of the spring is connected with the tail end of the pawl, and the other end of the spring is abutted against the step face of the step hole; and the lower surface of the upper mold plate is fixedly provided with a base, and a punch facing toward the concave mold is fixed on the base through a connecting block. The inner ball cage cavity mold-extrusion mold has reasonable and reliable structure and high working efficiency, the demolding of a work piece can be automatically carried out through the pawl elastically installed on the mold, automatic working is realized, the deformation of the work piece is avoided, the forming quality is ensured, the product has high precision, and the machined product has long service life.
Description
Technical field
The utility model relates to mould applications, specifically is a kind of internal spherical cage inner chamber cold extrusion die.
Background technology
Internal spherical cage and ectosphere generally are called the ball cage, are to be called " constant velocity cardan joint ", are the vitals in the car drivetrain system, and its effect is that the power with engine is delivered to two front vehicle wheels from speed changer, drives car and runs at high speed.
Internal spherical cage embryo spare obtains semi-finished product through after tentatively forging, and after saponification is handled, needs further process again, makes its inner chamber moulding, finally obtains finished product.The inner chamber of internal spherical cage generally adopts the cold-extrusion technology moulding, is placed on internal spherical cage in the die cavity exactly, at room temperature, exerts pressure to internal spherical cage through drift fixing on the forcing press, makes internal spherical cage generation plastic deformation and makes its inner chamber moulding.Owing to the axial pressure that receives of internal spherical cage, if on mould, internal spherical cage is carried out axial restraint, internal spherical cage is squeezed and deformity takes place and changes so, can not get final product.
The utility model content
The purpose of the utility model provides a kind of internal spherical cage inner chamber cold extrusion die, and the ratchet that is installed on the mould through elasticity carries out automatic demoulding to workpiece, realizes operation automation.
The technical scheme of the utility model is following:
A kind of internal spherical cage inner chamber cold extrusion die includes upper and lower template and die shoe, and described die shoe is fixedly mounted on the lower bolster; It is characterized in that: include die, around die, be respectively equipped with inside and outside armful of mould, the both sides of said die shoe are installed with screw rod respectively; Screwed togather gland on the described screw rod, described gland is provided with through hole, and gland is pressed and put on the end face of embracing mould outside; Described inside and outside armful of mould and gland are fixed on die on the die shoe; The sidewall of said die shoe is provided with radially stepped hole, is provided with ratchet in the stepped hole, and the front end of said ratchet extends to the lower port of die; Include spring, an end of said spring links to each other with the end of ratchet, and the other end of spring leans on the step surface of stepped hole; The lower surface of said cope match-plate pattern is installed with base, is fixed with the drift towards die through contiguous block on the described base.
Described internal spherical cage inner chamber cold extrusion die is characterized in that: be placed with workpiece in the described die, said drift moves down, and passes on the gland through hole and extend into extruding workpiece in the die, and the end of said ratchet leans the bottom at workpiece.
The beneficial effect of the utility model:
The utility model is rational in infrastructure, reliable, high efficiency, and the ratchet that is installed on the mould through elasticity carries out automatic demoulding to workpiece; Realize operation automation, avoided workpiece to deform, guaranteed Forming Quality; The product precision is high, and the finished product long service life of processing.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of internal spherical cage inner chamber cold extrusion die includes upper and lower template 1,2 and die shoe 3; Die shoe 3 is fixedly mounted on the lower bolster 2, includes die 4, around die 4, is respectively equipped with inside and outside armful of mould 5,6; The both sides of die shoe 3 are installed with screw rod 7 respectively, have screwed togather gland 8 on the screw rod 7, and gland 8 is provided with through hole 15; Gland 8 is pressed and is put on the end face of embracing mould 6 outside, and inside and outside armful of mould 5,6 and gland 8 are fixed on die 4 on the die shoe 3, and the sidewall of die shoe 3 is provided with radially stepped hole; Be provided with ratchet 9 in the stepped hole, the front end of ratchet 9 extends to the lower port of die 4; Include spring 10, an end of spring 10 links to each other with the end of ratchet 9, and the other end of spring 10 leans on the step surface of stepped hole; The lower surface of cope match-plate pattern 1 is installed with base 11, is fixed with the drift 13 towards die 4 through contiguous block 12 on the base 11.
Be placed with workpiece 14 in the die 4, drift 13 moves down, and passes on the gland 8 through hole 15 and extend into extruding workpiece 14 in the die 4; This moment workpiece 14 pressurizeds and in die 4, moving down, when workpiece 14 moves down into the end of ratchet 9, because the elastic force effect of spring 10; Ratchet 9 retainings are at workpiece 14 oral areas; Guarantee that workpiece 14 can be with not moving on the drift 13, make workpiece 14 automatic demouldings, finally make the inner chamber moulding of workpiece 14.
