Abstract
The invention is concerned with the fission module cavity of the metal extrusion press, includes: the nose beset block, the cavity, the feed opening set in the middle of the nose beset block, the opening sets at the feed end of the cavity, the nose beset block sets in the opening of the cavity. It is: sets position concave table on the outer wall of the nose beset block, sets the position protruding table at the corresponding position of the inner wall of the opening that assorts with the position concave table. The invention is: during the producing process, the nose beset block can change when it is broken, but the cavity can use repeatedly, which can reduce cost and extend the using life.
Description
Technical field:
Technical field of metal extrusion of the present invention is refered in particular to a kind of split type die cavity of metal extrusion press.
Background technology:
The continuously extruded technology of present copper material, the die cavity of its use is all-in-one-piece, as shown in Figure 1.Because the deformation temperature height of copper material, resistance of deformation is big, and thermal fluidity is poor, in the partly very easily deformation failure of process high temperature, high pressure effect lower mode cavity feeding mouth and nose of extruding.The overall performance of die cavity is relatively poor, and when nose partly is out of shape or cavity cracking, feeding mouth distortion, subsides, whole die cavity just lost efficacy, and especially the anti-red heat poor stability of nose very easily lost efficacy.In addition, monoblock type mold cavity configuration complexity, volume is little, and difficulty of processing is big, and the process-cycle is long, the manufacturing cost height.Die cavity is the crucial mould of continuous extrusion production, because its low life-span, expensively becomes the bottleneck that restriction is enhanced productivity and continuously extruded technology is applied.
Summary of the invention:
The objective of the invention is provides a kind of split type die cavity of metal extrusion press in order to solve the shortcoming of above-mentioned prior art.
For achieving the above object, technical scheme provided by the invention is: a kind of split type die cavity of metal extrusion press, and it includes, and nose is inserted and cavity, has feeding mouth in the middle part of nose is inserted, feeding end at cavity offers opening, and nose is inserted and is movably set in the opening of cavity.
On the outer wall that nose is inserted, offer the location concave station, and the corresponding position of the inwall of opening is provided with and locate the positioning boss that concave station cooperates.
After adopting technique scheme, in the process of producing, the inefficacy of die cavity just concentrates on nose inserts, and nose is inserted and lost efficacy, and change to get final product, and cavity can be reused.So just reduce production costs greatly, prolong the service life of cavity, and the processing of this split type die cavity becomes also simply, effectively cuts down finished cost.
Description of drawings:
Fig. 1 is the structure chart of prior art monoblock type die cavity;
Fig. 2 is the installation diagram of the split type die cavity of the present invention;
Fig. 3 is the split figure of the split type die cavity of the present invention;
Fig. 4 is Fig. 3 A partial enlarged drawing partly;
Fig. 5 is Fig. 3 B partial enlarged drawing partly.
The specific embodiment:
Now elaborate the present invention in conjunction with the accompanying drawings:
Shown in accompanying drawing 2～accompanying drawing 5, the split type die cavity of present embodiment includes nose and inserts 1 and cavity 2, and nose 1 middle part of inserting has feeding mouth 3, at an end of cavity 2 opening 4 is arranged, and nose is inserted and 1 is movably set in the opening 4 of cavity 2.Be provided with location concave station 5 in the insert bottom of 1 outer wall of nose, and the inwall relevant position of opening 4 is provided with the positioning boss 6 that cooperates with it, the effect of location is played in the cooperation of two steps when mounted.Calculate according to the combination die optimum theory, its bulk strength of die cavity of the present invention improves twice than traditional integral formula die cavity.Simultaneously nose is inserted and adopted the specific aim Technology for Heating Processing, make it obtain best performance, make the combination property of die cavity reach best.
Nose of the present invention is inserted and 1 is used common hot die steel, adopts said structure, improves three to five times the service life of die cavity.Combined type die cavity processing cost of the present invention is original 1/3rd, and fabrication cycle shortens greatly.
