Abstract
The utility model relates to a promote extrusion tooling of aluminum alloy side pipe surface finish by a wide margin, including last mould and lower mould, wherein go up to make on the mould four aluminum product that are even symmetric distribution and extrude the hole, the square mold core of fillet has still been made at the middle part of these four extrusion holes, the lower mould is made correspondingly has fillet side pipe extrusion hole, and its characteristics lie in it has still been made to go up between mould and the lower mould and has welded the room, and the high H of this welding room is 30mm-60 mm. Make the mould can increase the aluminum product raw materials extrusion pressure by the crowded mould in through this seam room to this density that can increase substantially the aluminum product raw materials makes aluminum alloy side's pipe just have extremely smooth and bright surface by extrusion moulding back, and then has saved the post treatment process of square pipe, has saved the production and management cost of enterprise.
Description
Technical field
The utility model relates to a kind of fillet aluminum alloy square tube extrusion die structure.
Background technology
At present, aluminium alloy pipe is after being extruded moulding, and the fineness of tube surfaces, brightness are mostly relatively poor, mostly also will carry out the surface finish in later stage and handle.So, the production process that not only makes aluminium alloy pipe is comparatively complicated, and has directly increased the weight of the production and operation cost of enterprise, and makes the inferior quality, of low grade of tubing that enterprise produces, and on market, has no advantage and can say.
The utility model content
The purpose of the utility model is to provide a kind of can promote aluminum alloy square tube surface smoothness, brightness significantly; And need not carry out the polishing in later stage; Favourable saving production process reduces the production and operation cost of enterprise, improves the extrusion die of the market competition advantage of product.
The technical scheme of the utility model is achieved in that
A kind of extrusion die that promotes the aluminum alloy square tube surface smoothness significantly; Comprise patrix and counterdie; Wherein make four aluminiums that are distribution symmetrically on the patrix and clamp-on the hole, also made the rounded square core rod at these four middle parts of clamp-oning the hole, said counterdie has been made fillet square tube extrusion cavities accordingly; Its characteristics are also to have made between said patrix and the counterdie seam chamber, and the height H of this seam chamber is 30mm-60mm.
In order further to promote the space of seam chamber again, above-mentioned per two tops of clamp-oning the hole wall between the hole become the cone-shaped top.
The technique effect of the utility model:
The utility model is through being provided with the structure of seam chamber in mould; Make mould can increase the aluminium raw material nip pressure that is squeezed in the mould through this seam chamber; With this density that can increase substantially the aluminium raw material, make aluminum alloy square tube be extruded moulding after, just have dead smooth with the light the surface; And then saved square tube post-processed operation, saved the production and operation cost of enterprise.In addition, can also compress the joint close between per share aluminium raw material and the aluminium raw material indirectly, thereby promote the quality of aluminum alloy square tube further, improve the market competition advantage of product.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
Fig. 2 is the Facad structure sketch map of the patrix of the utility model.
Fig. 3 is the broken section structural representation of the hole wall of the utility model.
The specific embodiment
Like Fig. 1 and shown in Figure 2; The described a kind of improvement fillet aluminum alloy square tube extrusion die of the utility model comprises patrix 1 and counterdie 2, wherein makes four aluminiums that are distribution symmetrically on the patrix 1 and clamp-ons hole 11; Also made rounded square core rod 12 at these four middle parts of clamp-oning hole 11; Said counterdie 2 has been made fillet square tube extrusion cavities 21 accordingly, and is in order to realize the purpose of the utility model, as shown in Figure 1; Also made seam chamber 13 between above-mentioned patrix 1 and the counterdie 2, this seam chamber 13 is to be made up of after the half seam chamber butt joint in a left side of counterdie 2 half seam chamber, the right side of patrix 1.And half seam chamber, the right side of said patrix 1 is opened between the side and per two hole walls of clamp-oning between the hole 11 14 of square core rod 12.The preferred height H of this seam chamber 13 is 30mm-60mm.Mainly can increase the aluminium raw material nip pressure that is squeezed in the mould through this seam chamber 13; Can increase substantially the density of aluminium raw material with this; After making aluminum alloy square tube be extruded moulding; Just have the surface of dead smooth and light, and then saved square tube post-processed operation, saved the production and operation cost.In addition, can also compress the joint close between per share aluminium raw material and the aluminium raw material indirectly, thereby further improve the quality of square tube, improve the market competition advantage of product.Simultaneously; In order further to promote the space of seam chamber 13 again; As shown in Figure 3, can also adopt per two tops of clamp-oning the hole wall 14 between the hole 11 are become the cone-shaped top, come to promote further again the space of seam chamber 13 with this; Accomplish to increase further again the pressure of the aluminium raw material extruding that is squeezed in the mould, promote the quality of product.
On the basis of aforementioned schemes; In order to ensure square tube in the punching press application process in later stage; Can not go out the phenomenon of crackle, slight crack; Like Fig. 1 and shown in Figure 2, four fillets and four Kong Xincheng that clamp-on hole 11 of said square core rod 12 are symmetrical set, four filleted corners of said extrusion cavities 21 are also corresponding be arranged to identical with the orientation of 12 4 fillets of square core rod.The utility model is through overcome the technological prejudice of this area simply, dexterously; Four fillets and four Kong Xincheng that clamp-on the hole of the square core rod of extrusion die are symmetrical set, also are arranged to identically with four filleted corners of extrusion cavities are also corresponding simultaneously, make square tube when extrusion modling with the orientation of four fillets of square core rod; Clamp-on four strands of aluminium raw materials that the hole enters into mould from four; Joint close has been moved on to four sides of square tube simply, dexterously between per share aluminium raw material and the aluminium raw material, and this four side just is in the stressed position of non-positive facial disfigurement in the punching press deformation processing in later stage; Being in stress deformation position, front is four bights of square tube; Thereby just can guarantee that square tube in punching press deformation processing process, the phenomenon in crackle, crack can not occur, and then just guarantee the later stage application quality of square tube.
