Extrusion die of shoulder hole barrier part, including the template, install at the last terrace die of template lower part, the die holder under lieing in the terrace die, install die on the die holder, lie in the lower punch of the vertical setting of die die cavity and be used for the annular backing -out punch of the ejection of compact, the lower punch be the axle column structure of multistage ladder, and the diameter of lower punch scales up step by step, its characterized in that, the upper end of lower punch has 5 -8o's fillet, the middle ladder of lower punch all has 45o's cone angle, the lower extreme of lower punch is tapering axle construction, and its cone angle is 10o.
Description
Technical field
The utility model relates to the extrusion forming technology of barrier part, is specially a kind of extrusion die of shoulder hole barrier part.
Background technology
The characteristic feature of trapezoidal hole barrier part is that in it, blind hole becomes stepped, and its molding mode usually adopted is cold extrusion, cold extrusion shaped employing be horizontal extruder, forward extrusion mould installed by horizontal extruder, for the processing and forming of this barrier part.The existing forward extrusion mould shaping for shoulder hole barrier part, its primary structure comprises upper male mould, the die be arranged on die holder, be positioned at the lower punch of die die cavity and the annular backing-out punch for discharging, in order to mold the shoulder hole of barrier part inside, ladder shaft-like made by lower punch, but existing mould often has the following disadvantages: due to the structure of lower punch ladder shaft-like, it can increase the resistance of metal flow, and destroys the continuity of extruded layer surface lubricant.
Utility model content
The utility model is intended to the extrusion die providing a kind of shoulder hole barrier part, easily hinders metal flow with the lower punch solving existing mold, destroys the successional problem of lubricant flowing.
The extrusion die of the shoulder hole barrier part in this programme, comprise template, be arranged on the upper male mould of template bottom, be positioned at the die holder immediately below upper male mould, the die be arranged on die holder, be positioned at the die die cavity vertically lower punch of setting and the annular backing-out punch for discharging, described lower punch is the shaft-like structure of multistage ladder, and the diameter of lower punch increases progressively step by step, it is characterized in that, the upper end of lower punch has 5-8
ofillet, the middle ladder of lower punch all has 45
ocone angle, the lower end of lower punch is taper shaft structure, and its cone angle is 10
o.
The beneficial effects of the utility model are as follows: make 5-8 by the upper end of lower punch
ofillet, the middle ladder of lower punch all makes 45
ocone angle, and the lower end of lower punch is taper shaft structure, and its cone angle is 10
o, can ensure the smoothness of metal flow, be out of shape evenly and reduce resistance, lubricant also continuously can add in newborn compressive surface and not be cut off, and guarantees carrying out smoothly of extrusion process.
Further, die holder top has mounting groove, and be provided with the second cushion block, the second fixed cover of ring-type and the supporting seat of ring-type in mounting groove from top to bottom successively, die is bearing on supporting seat.The extruding force be subject in extrusion process due to die is comparatively large, adopts the structure of this transmitting force step by step, can effectively reduce the crimp of die, improve die rigidity.
Further, die stretches out described mounting groove, and die holder upper periphery has been threaded the second nut, and inner face and an annular sleeve of the second nut offset, and the inner circle of annular sleeve pushes against the cylindrical of die.By arranging annular sleeve and the second nut, effectively ensure the intensity of stretching out the die of mount pad part.
Further, the bottom of template is provided with integrated annular mount pad with it, the first fixed cover of ring-type is provided with in mount pad, the cylindrical of mount pad is threaded the first nut, the lower end of the first nut bends inwards, its inner face and upper male mould offset, and the lower surface of the first fixed cover and the inner face of nut offset.By arranging the first nut, the not only installation of expediently punch and the first fixed cover, and the lower surface of the first fixed cover and the inner face of nut offset, and can strengthen the intensity of the first nut end face.
