Abstract
The embodiment of the utility model discloses an upper die of a divergent die; and an arc-shaped transition surface is arranged between the first side and the upper surface, between the second side and the upper surface, between the first side and the lower surface and between the second side and the lower surface of a bridge of the upper die respectively. In the upper die of the divergent die, the arc-shaped transition surface is arranged between the first side and the upper surface, between the second side and the upper surface, between the first side and the lower surface and between the second side and the lower surface of the bridge of the upper die, so that the contact area between the two ends of the bridge and a cast ingot in the extruding process of the cast ingot can be enlarged, and the bearing area of the bridge can be enlarged; and meanwhile, the acting force of the cast ingot applied on the bridge can be better resolved by the arc-shaped transition surfaces, so that the bearing strength of the bridge is reduced, and the service life of the bridge is prolonged. The utility model also discloses the divergent die.
Description
Technical field
The utility model relates to hollow aluminum profile extrusion die manufacturing technology field, more particularly, relates to a kind of patrix of divergent die, and the utility model also relates to a kind of divergent die that includes above-mentioned patrix.
Background technology
The hollow aluminum section bar is that ingot casting carries out passing through divergent die and moulding after the hot extrusion.Divergent die is divided into upper die and lower die, please refer to accompanying drawing 1, the production process of hollow aluminum section bar is as follows: ingot casting 5 is placed in the recipient 1, be arranged in the die sleeve 2 of recipient 1 one ends divergent die is installed, the patrix 6 and the counterdie 7 of divergent die achieve a fixed connection by screw rod 3, the pressed end of extrusion axis 4 is provided with dummy block 41, under the extruding of extrusion axis 4 (among Fig. 1, pressure F), ingot casting 5 enters into seam chamber 8 from the tap hole 71 of divergent die patrix, and, form hollow aluminum section bar 9 (concrete structure please refer to Fig. 2) by counterdie 7 derivation.
From the production process of above-mentioned hollow aluminum section bar as can be seen, divergent die is when producing the hollow aluminum section bar, when ingot casting passes the tap hole of patrix, the squeeze pressure of extrusion axis mainly concentrates on the bridge of patrix, because ingot casting has flowability in the process of hot extrusion, for the ease of flowing of ingot casting in the extruding, in the design process of patrix, the edge of bridge generally is designed to the shape of chamfering.
Please refer to accompanying drawing 3-4, wherein, Fig. 4 is the schematic cross-section of the bridge of existing a kind of divergent die patrix, the upper surface of bridge becomes chamfering with following edge designs, please refer to accompanying drawing 4, between first side 721 of bridge 72 and upper surface 727, be provided with to be provided with between chamfering 725, first side 721 and the lower surface 728 to be provided with between chamfering 726, second side 722 and the lower surface 728 between chamfering 723, second side 722 and the upper surface 727 and be provided with chamfering 724.Above-mentioned chamfering is generally 30 °.Above-mentioned divergent die chamfering is suitable for pushing mild alloy, as section bars such as 6063T1,6061T5,6005T5,6001H112, when the extruding hard alloy, during as section bars such as 7004T5,7005T5, LF2R, because this alloy rigidity height needs the bigger pressure that reaches during extruding, the ingot casting made of the alloy of high rigidity mobile relatively poor in mould when extruding simultaneously, so the huge pressure that the bridge of the patrix of divergent die bears in extrusion process causes the bridge fracture of patrix, the life-span of having reduced divergent die easily.According to the relevant data statistics, the every mold extruding of our the normal divergent die that uses is less than behind 1 ton of section bar, and mould will be scrapped, and has directly increased production cost, has reduced the profit of product.
The utility model content
In view of this, the utility model provides a kind of patrix of divergent die, improves by the structure to patrix, has strengthened the ability to bear of patrix, has prolonged the service life of patrix.
In order to achieve the above object, the utility model embodiment provides following technical scheme:
A kind of patrix of divergent die is provided with arc transiting surface between first side of the bridge of this patrix and upper surface, second side and upper surface, first side and lower surface and second side and the lower surface.
Preferably, in the patrix of above-mentioned divergent die, described arc transiting surface is the evagination arc transiting surface.
Preferably, in the patrix of above-mentioned divergent die, described arcwall face is the indent arc transiting surface.
Based on the patrix of the above-mentioned divergent die that provides, the utility model embodiment also provides a kind of divergent die, and this divergent die comprises counterdie and foregoing patrix.
As shown from the above technical solution, the utility model embodiment provides in the patrix of divergent die, between first side of the bridge of patrix and upper surface, second side and upper surface, first side and lower surface, second side and lower surface, arc transiting surface is set all, arc transiting surface has improved the two ends of bridge in the process of ingot casting extruding, contact area with ingot casting, improve bridge and born the area of extruding, by arc transiting surface the active force that ingot casting imposes on bridge is realized decomposing better simultaneously, reduce the bearing strength of bridge, prolonged the service life of bridge.
