3rd purpose of the present utility model is to provide upsetting of the above-mentioned continuous cone upsetting die to super large ratio of height to diameter bar
Thick method.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of continuous cone upsetting die of super large ratio of height to diameter bar, including cooperate cavity plate and punch-pin, cavity plate and
The shaping wall of punch-pin has identical taper, and its cone angle is 4~30 °；If the cavity plate is removable by axially distributed dried layer
The cavity plate module unloaded is installed and formed, if the punch-pin is installed by the dismountable punch-pin module of axially distributed dried layer form, and
The jumping-up number of times of the number of plies of cavity plate and the number of plies of punch-pin with setting is equal, the height of punch-pin module and the height pair of cavity plate module
Should set.
The shaping wall of cavity plate and punch-pin is respectively provided with certain taper, wherein, taper refers to the basal diameter and cone of circular cone
The ratio between height, is then upper and lower two bottom diameter of a circle difference and the ratio of frustum cone height if round platform.Cone angle cuts for the axle of circular cone
Angle between two buses in face.
Shaping wall, refers to the interior sidewall surface of cavity plate and the outer side surface of punch-pin.
Refer at least two-layer if dried layer, can be three layers, four layers, five layers and more layers, the ratio of height to diameter of original blank is got over
Greatly, the number of plies is more.
It can be seen from the relation that punch-pin and cavity plate coordinate, the outer surface of punch-pin should be truncated cone-shaped, and the inner cavity of cavity plate is same
It is truncated cone-shaped, when punch-pin inserts cavity plate certain depth, the lateral surface of punch-pin should be completely attached to the internal face of cavity plate.According to
Normal mounting means explains that punch-pin is arranged on upper bolster, now, the area of the lower surface of the truncated cone-shaped of punch-pin is less than upper
The area of end face, is inverted truncated cone-shaped.Cavity plate is arranged on die shoe, and the inner cavity of cavity plate is also inverted truncated cone-shaped.Institute
So that in order to realize coordinating, the structure of punch-pin and cavity plate at this is clearly.

Bar deforms, because the ratio of height to diameter of bar is larger, although a certain degree of unstable phenomenon can occur, due to cavity plate inwall
Taper it is smaller, less, even if bar unstability and bending, but the bar of bending can contact quickly in the inwall gap of bar and cavity plate
To cavity plate inwall, and under the effect of contraction of cavity plate inwall, slight bending is corrected quickly, its unstability and bend and
When suppress, be not in because of fold defect caused by slight unstability.When punch-pin reaches the depression stroke of regulation, blank is full of mould
Tool die cavity, the jumping-up part lower end diameter of acquisition is held essentially constant, and upper end diameter increase, average ratio of height to diameter is obviously reduced.
