Fig. 2 is the structural representation of the utility model tapering core rod;
Fig. 3 is the internal structure schematic diagram of the utility model stereoscopic-state.
The implication of number in the figure: 1-top die head; 2-die sleeve trim ring; 3-workpiece; 4-tapering core rod; 5-die sleeve; 6-fixed jacket; 7-core rod seat; 8-die holder; 9-forcing press lower table; 10-backform bar.
The specific embodiment
Below in conjunction with drawings and Examples, to the specific embodiment of the present utility model as preferred detailed description.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1-Fig. 3, the easy material returned cold extrusion mould of a kind of major axis device, comprise forcing press lower table 9 and backform bar 10, on forcing press lower table 9, be provided with die holder 8, on die holder 8, be provided with core rod seat 7, on core rod seat 7, be provided with die sleeve 5, in the inside of die sleeve 5, be provided with tapering core rod 4, outer setting at die sleeve 5 has fixed jacket 6, and be provided with die sleeve trim ring 2 (not being ejected while making die sleeve 5 in the material returned) in die sleeve 5 and the upper surface of fixed jacket 6, described fixed jacket 6 is arranged on die holder 8, above described tapering core rod 4, be provided with top die head 1, in tapering core rod 4, be provided with workpiece 3, described core rod seat 7, the centre of die holder 8 and forcing press lower table 9 all offers through hole, (backform bar 10 is material returned push rod to described backform bar 10, the workpiece processing 3 is ejected to tapering core rod 4) run through this through hole.
As preferably, above-mentioned tapering core rod 4 is comprised of the module of four equal portions that (endoporus of tapering core rod 4 can be by workpiece and the geomery that will extrude requirement processing; Tapering core rod 4 reaches this and requires laggard line cutting quarter, in order quarter is put into die sleeve 5).
As preferably, the vertical cross-section of above-mentioned tapering core rod 4 is shaped as isosceles trapezoid, and wherein the length of trapezoidal upper base is greater than the length of going to the bottom.
As preferably, the outer surface of above-mentioned tapering core rod 4 and the inner surface of die sleeve 5 are suitable, and the through hole of core rod seat 7 is inserted in the bottom of tapering core rod 4.
