Abstract
The utility model discloses a shape extruding die of an aluminum tube. The shape extruding die comprises an upper die and a lower die, wherein a feeding duct which penetrates through the two sides of the lower die is formed in the center of the lower die; a connecting bridge is fixedly arranged on the inner wall of the feeding duct in a spanning manner; a lower die shaft is fixedly arranged on the connecting bridge; an upper die hole is formed in the center of the upper die; and when the upper die and the lower die are combined, a material extruding shaping seam is formed between the lower die shaft and the upper die hole, the connecting bridge is straight, the thickness of the connecting bridge is gradually enlarged from outside to inside, and the whole connecting bridge is of a bilateral symmetry structure. The shape extruding die has the advantages that the integration degree of aluminum is high, and the molding quality of aluminum tubes is good.
Description
Technical field
The utility model relates to a kind of metal processing mold, specifically refers to a kind of extrusion die tool of aluminum pipe.
Background technology
Existing aluminum pipe generally all is to adopt the preparation of hot extrusion molding technique, and the parts of its core are exactly the extrusion die tool.The structure of the type mould of existing aluminum pipe has generally comprised upper die and lower die, the center of counterdie is provided with lower mold shaft, and the center of patrix is provided with nib, behind the upper die and lower die matched moulds, be formed into groove part between this time mold shaft and the upper nib, the aluminium material claims counterdie to carry out by becoming groove part to form aluminum pipe.In order to locate fixing lower mold shaft, on counterdie, also be provided with connecting bridge.The connecting bridge of the counterdie of the extrusion die tool of existing aluminum pipe is generally the central cross structure, and the shortcoming of its existence is: the aluminium material is divided into 4 sections and then merge and to be squeezed into pipe, and the aluminium material is relatively poor in the fusion degree that becomes groove part, the quality of serious aluminum pipe.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and provides a kind of aluminium material fusion degree that can allow good, and improves the extrusion die tool of the aluminum pipe of aluminum pipe quality.
For achieving the above object, the technical solution of the utility model is to include counterdie and patrix, the center of described counterdie is provided with the charging duct that connects both sides, the vertical connecting bridge that is provided with of fixed span on the inwall in described charging duct, be fixedly installed lower mold shaft on this connecting bridge, described patrix center is provided with nib, under the upper die and lower die matched moulds state, consist of material extrusion between this time mold shaft and the upper nib and become groove part, described connecting bridge is yi word pattern, it is large consistent after crossing the diameter that narrows down to lower mold shaft that the thickness of this connecting bridge becomes from outside to inside gradually, and integral body is the left-right symmetry structure.The utility model adopts connecting bridge is designed to yi word pattern, stride and stand on the inwall of charging duct, the preparation of aluminium material is divided into two sections, then by merging after the connecting bridge, and then become to extrude the formation aluminum pipe in the groove part in material extrusion, merging again than traditional 4 sections, the utility model merging point is a half, therefore can put forward preferably the fusion degree of high aluminium material, improve the quality of aluminum pipe moulding.In addition, the utility model becomes large from outside to inside gradually by the thickness with connecting bridge, and integral body is the left-right symmetry structure, the aluminium material is in passing through the process of connecting bridge, because the outer end thickness of connecting bridge is less, the aluminium material can be cut open fast, then enters in the charging duct, and in fill process, have in the thickness of connecting bridge and become gradually from outside to inside large, can prevent that the aluminium material is flattened cutting, and cause the aluminium material to be difficult to the fine and close defective that merges, by this setting, change the direction of advance of aluminium material, the aluminium material at rear can apply to the aluminium material that the place ahead will be merged one towards its active force that merges face, therefore, can greatly improve the fusion performance of aluminium material.
The both sides of two junctions are provided with level and smooth indent crank slot along feedstock direction about further described connecting bridge being set and charging duct inwall contacts.By this setting, one has 4 indent crank slots, enter in the process at the aluminium material, play the effect of 4 locating slots, allow the aluminium material everywhere the direct of travel of position be consistent, therefore, the aluminium material at rear is consistent to the active force that is applied on its fusion face of the aluminium material to be merged in the place ahead, can greatly improve the fusion performance of aluminium material.
Further arranging is that a described lower mold shaft end corresponding with upper nib is round table-like.
The bottom surface periphery that further setting is described patrix is provided with annular convex shoulder, is provided with the annular groove that cooperates with the annular convex shoulder location on the described counterdie.
The utility model has the advantages that the aluminium material merges degree good, the aluminum pipe Forming Quality is good.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.

The specific embodiment
Below by embodiment the utility model is carried out concrete description; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned utility model.
The specific embodiment of the present utility model shown in Fig. 1-5, include counterdie 1 and patrix 2, the center of described counterdie 1 is provided with the charging duct 11 that connects both sides, the vertical connecting bridge 12 that is provided with of fixed span on the inwall in described charging duct 11, be fixedly installed lower mold shaft 13 on this connecting bridge 12, described patrix 2 centers are provided with nib 21, under patrix 2 and the counterdie 1 matched moulds state, consist of material extrusion between this time mold shaft 13 and the upper nib 21 and become groove part 14, the described described lower mold shaft 13 of the present embodiment and upper nib 21 corresponding ends 131 are round table-like, with this, can form above-mentioned material extrusion and become groove part 14, in addition, the diameter that also can adopt nib 21 can realize also that greater than the modes such as diameter of lower mold shaft 13 material extrusion becomes groove part 14, and the aluminium material becomes groove part 14 to extrude the formation aluminum pipe from this material extrusion.
In addition, the described connecting bridge 12 of the present embodiment is yi word pattern, and it is large that the thickness of this connecting bridge becomes from outside to inside gradually, and the diameter that narrows down to lower mold shaft is consistent after crossing, and referring to Fig. 3 and Fig. 4, and integral body is the left-right symmetry structure.In addition, the described connecting bridge 12 of the present embodiment contact with charging duct 11 inwalls about the both sides 121 of two junctions be provided with level and smooth indent crank slot 122 along feedstock direction.This setting can greatly improve the fusion degree of aluminium material, improves the Forming Quality of aluminum pipe.
