Description
Technical field
The utility model relates to a kind of extrusion die, is specially a kind of metal cylindrical member indirect-extrusion mould, belongs to metallic extrusion molding field.
Background technology
The backward extrusion of metal cylindrical member, the mould conventionally adopting is planar base surface.There is larger stretching class distortion in barrel part in the time that backward extrusion is out of shape, and cylinder bottom point deflection deficiency.The plastic deformation of metal is the essential condition of improving product intensity.Therefore the strengthening effect that cylinder bottom point is brought by plastic deformation is weaker than barrel part, causes the bulk strength of finished product not high.In order to overcome the deficiency of above-mentioned mold mechanism, according to Design and manufacture experience for many years, the utility model provides following a kind of mould structure to solve this difficult problem.
Utility model content
The purpose of this utility model is to provide a kind of metal indirect-extrusion mould, is weaker than barrel part to overcome the strengthening effect being brought by plastic deformation cylinder bottom point, causes the not high problem of bulk strength of finished product.
In order to realize the purpose of this utility model, the utility model is taked following technical scheme:
A kind of metal cylindrical member indirect-extrusion mould, this mould comprises mandrel, mandrel termination, recipient and baffle plate, described mandrel and mandrel termination constitute punch, described recipient and baffle combination form die, described mandrel termination has circular arc convex surface, and described baffle plate has arc-shaped concave.
Between described mandrel and mandrel termination, for being fixedly connected with, described mandrel termination can be threaded connection and be fixed on mandrel, and mandrel and mandrel termination constitute punch.
Described recipient is fixed on extruder moving beam, and described baffle plate is fixed on the forebay of extruder, and between described recipient and baffle plate, face contact, constitutes die.Active force between recipient and baffle plate, is controlled by the active force between crossbeam and forebay.
Between the circular arc convex surface of mandrel termination and the arc-shaped concave of baffle plate, there is certain matching relationship, at the bottom of both coordinate and are shaped tin.
Metal cylindrical member indirect-extrusion mould of the present utility model, mandrel can axially repeatedly move in recipient, and mandrel termination has semi arch convex configuration, and the baffle plate with circular arc concave surface and recipient form die jointly.The utility model coordinates by indirect-extrusion mould inner spindle termination circular arc convex surface and baffle plate arc-shaped concave, makes the outer surface of cylinder body bottom be configured as outer lug boss structure, has increased the deflection of cylinder body bottom.
Mandrel, mandrel termination, recipient and the baffle plate of mould of the present utility model are replaceable, can the difform extrusion of extrusion molding.Mould structure is simple, is applicable to not requiring the cylindrical member backward extrusion of planar base surface.Can realize the different distortion amount of recipient bottom by changing the arc profile size of mandrel termination and baffle plate.A kind of metal indirect-extrusion mould has solved the lower problem of intensity that cylindrical member backward extrusion deformation of bottom deficiency causes.

Detailed description of the invention
As shown in Figure 1, the utility model metal cylindrical member indirect-extrusion mould, is the mould that extrusion metal has bottomless drum shape part, and punch and the die of mould are combined type.This mould comprises mandrel 1, mandrel termination 2, recipient 3 and baffle plate 5, and mandrel 1 constitutes punch with mandrel termination 2, and recipient 3 constitutes die with baffle plate 5, and mandrel termination 2 has circular arc convex surface, and baffle plate 5 has arc-shaped concave.
Between mandrel 1 and mandrel termination 2, for being fixedly connected with, mandrel termination 2 can be threaded connection and be fixed on mandrel 1, and mandrel 1 and mandrel termination 2 constitute punch.Mandrel 1 is fixed on the main piston of extruder, and mandrel termination 2 is fixed on mandrel 1.
Recipient 3 is fixed on extruder moving beam, and baffle plate 6 is fixed on the forebay of extruder, and recipient 3 contacts with 5, baffle plate, constitutes die.Active force between recipient 3 and baffle plate 5, is controlled by the active force between crossbeam and forebay.
Between the circular arc convex surface of mandrel termination 2 and the arc-shaped concave of baffle plate 5, there is certain matching relationship, at the bottom of both coordinate and are shaped tin.
Blank 4 is placed between the die that punch that mandrel 1 and mandrel termination 2 form and recipient 3 and baffle plate 5 form, mandrel 1 can be in the interior axially motion repeatedly of recipient 3, mandrel termination 2 has semi arch convex configuration, baffle plate 5 has circular arc concave surface, at the bottom of cooperatively interacting between the circular arc convex surface of mandrel termination 2 and the arc-shaped concave of baffle plate 5 and being shaped tin, by adjusting the geomery of two fit circular arc, the different distortion amount of bottom can realize cylindrical member backward extrusion time.
The utility model coordinates by indirect-extrusion mould inner spindle termination circular arc convex surface and baffle plate arc-shaped concave, makes the outer surface of cylinder body bottom be configured as outer lug boss structure, has increased the deflection of cylinder body bottom.Mandrel termination, recipient and baffle plate are replaceable, can the different extrusions of backward extrusion.
