Abstract
The utility model discloses an extrusion die for a deep tapered part. The extrusion die comprises a sliding block of a press machine, an upper die base, a convex die, a concave die, a material pressing cylinder, a press screw and a spring, wherein the upper end of the convex die is connected with the upper die base in a positioning way through a bolt; the upper die base is connected with the sliding block of the press machine in a positioning way through a bolt; the material pressing cylinder is sleeved on the convex die; the upper end of the material pressing cylinder is connected with the upper die base in an axial moving manner through the press screw and is sleeved by the press screw for axial limitation; the spring is axially arranged between the material pressing cylinder and the upper die base and is used for pressing the material pressing cylinder downwards; the material pressing cylinder and the concave die are in clearance fit; and the lower end of the material pressing cylinder is in a cone shape. During the extruding of the extrusion die, the material pressing cylinder exerts the effects of guiding and positioning, so that the problem of instability during extruding can be effectively solved.
Description
Technical field
The utility model relates to the pressure processing field, relates to a kind of structure of extrusion of dark Tapered Cup in particular.
Background technology
Because the draw ratio of dark Tapered Cup is bigger, so add repeatedly extrusion modling of needs usually in man-hour.Because the frictional resistance of male cone (strobilus masculinus) is inhomogeneous in extrusion process; Cause punch summit and workpiece contact point to produce the skew of sliding; And then the extruding unstability appears, profile decentraction in the workpiece after the extruding appears, wall thickness is inhomogeneous, oral area is crooked and problem such as punch cone tip part bending.In order to address the above problem, be the pressing method of platform with the taper hole top usually, but platform can limit the extruding degree of depth of Tapered Cup when big; Platform is little and be easy to generate the skew of sliding, and therefore need progressively reduce the taper hole top platform, increases the extruding degree of depth through repeatedly pushing; In addition; Also need machined with the taper hole of the method extruding is follow-up, this method manufacturing procedure is many, and production efficiency is low.Therefore, some producer directly takes machined to this type of dark Tapered Cup, but the turning amount is very big, and stock utilization is low.
Summary of the invention
The purpose of the utility model is to provide a kind of extrusion die of dark Tapered Cup, and this structure has the function of guiding, workpiece pressing location and the extruding back demoulding, can solve the deep processing part and push unsettled technical problem.
In order to achieve the above object, the solution of the utility model is:
A kind of extrusion die of dark Tapered Cup comprises press ram, upper bolster, punch and die.The punch upper end is located by connecting through bolt and upper bolster, and upper bolster is located by connecting through bolt and press ram.
On punch, be with the binder tube, but the upper end of said binder tube realizes that through pressing spiral shell and upper bolster axial displacement is connected, and by pressing swivel nut to live in capable axial limiting; Between binder tube and upper bolster, axially be provided with spring, spring with the binder tube to pressing down.It is conical that binder tube and die matched in clearance, its lower end are, more than or equal to the tapering of dark Tapered Cup.
Particularly, there is a cavity said upper bolster lower end around the installed position of punch, and said binder tube upper end outer wall has convex shoulder, and said convex shoulder puts in the cavity, carries out axial limiting by pressing spiral shell to entangle from below.
On the lower inner wall of said binder tube boss being arranged, conflicts on said boss in the lower end of said spring, and upper end and upper bolster are inconsistent.
The utility model is through being provided with the binder tube on punch; The binder tube plays the effect of guiding and location in extrusion process; Prevent the instability problem that occurs in the extrusion process effectively; The binder tube is released punch under the effect of spring from workpiece when punch upwards returns, and accomplishes an extrusion process.
The utility model is simple and reliable for structure, and low cost of manufacture, has reduced the extruding and the aided process of dark tapered squeezing part, and need not to carry out machined after the internal taper hole shaping again, and production efficiency is high, the saving raw material.

Fig. 2 is extruding back mould structure sketch map figure.
Wherein: the 1-die, the 2-blank, 3-binder tube, the 4-punch, the 5-spring, 6-presses spiral shell, 7-upper bolster, 8-cavity.
The specific embodiment
Come in conjunction with the drawings below the utility model is set forth in detail.
As shown in Figure 1, a kind of structure of extrusion of dark Tapered Cup comprises press ram, upper bolster 7, punch 4, die 1, binder tube 3, spring 5 and presses spiral shell 6.Punch 4 is located by connecting through bolt and upper bolster 7, and upper bolster 7 is located by connecting through bolt and press ram.There is a cavity 8 upper bolster 7 lower ends around the installed position of punch 4.On punch 4, be arranged with binder tube 3, the external diameter of said binder tube 3 is consistent with the internal diameter of die 1, and binder tube 3 upper end outer walls are provided with a convex shoulder, and binder tube 3 cooperates with the recess of die 1, and it is conical that its lower end is, more than or equal to the tapering of dark Tapered Cup.The lower end inwall of binder tube 3 is provided with a boss, and the internal diameter of boss is consistent with the diameter of punch 4.Spring 5 is between binder tube 3 and punch 4, and the roof of the cavity of upper end and upper bolster 7 is inconsistent, and the boss of lower end and binder tube lower end inwall is inconsistent.Press spiral shell 6 to be and cover shape, be enclosed within binder tube 3 upper ends, and be spirally connected with upper bolster 7 lower ends.The convex shoulder of binder tube 3 upper ends puts in the cavity 8 of upper bolster, carries out axial limiting by pressing spiral shell 6 to entangle from below.
The course of work:
As shown in Figure 2, under the drive of press ram, punch 4 moves downward with binder tube 3; Binder tube 3 cylindricals and die 1 endoporus oral area automatic guiding mould; Binder tube 3 at first contacts blank 2 and under the effect of spring 5, blank 2 is compressed the location, punch 4 descending beginning extrusion billets 2, and binder tube 3 is pushed down blank 2 always in this process; Binder tube 3 is directly released punch 4 under the effect of spring 5 from workpiece when punch 4 upwards returns, and accomplishes an extrusion process.
