Abstract
The utility model relates to an improvement fillet aluminum alloy side pipe extrusion tooling, 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 fillet side pipe correspondingly and is extruded the hole, and its characteristics lie in four fillets of square mold core are the symmetry setting with the hole center of four extrusion holes, four interior fillets of extruding the hole also correspond to set up to the position the same with four fillets of square mold core. The utility model discloses a simple, overcome technical bias in this field ingeniously, make the square pipe that extrusion obtained, in the stamping deformation course of working in the later stage, crackle, cracked phenomenon can not appear, and then just guaranteed the later stage application quality of square pipe.
Description
Technical field
The utility model relates to a kind of fillet aluminum alloy square tube extrusion die structure.
Background technology
As shown in Figure 4; Be engaged in the technical staff of mould development at present; When the mould of exploitation aluminum alloy square tube or fillet square tube; All be four bights of the square core rod 10 of mold 40 to be designed to habitually and four hole walls of clamp-oning between the hole 20 30 of this mold are symmetrical perhaps unalterablely, and little by little formed a kind of comparatively obstinate technological prejudice, and be difficult in good time, corrigendum is come neatly.Yet, adopt the aluminum alloy square tube of the mould institute extrusion molding of this structural design, when the end face to square tube carried out punch process, crackle very easily appearred in its four bights, and then had greatly influenced the later stage application quality of square tube.And after the square tube extrusion molding, before processing, be to can't see any joint close or crackle, slight crack on the position, angle of square tube or the surface.Why can be after punch process; The basic reason that crackle, slight crack occur is: square tube adds man-hour extruding; Clamp-on four strands of aluminium raw materials that the hole gets into from four; Joint close just is on four bights that are extruded the square tube after the moulding between per share aluminium raw material and the aluminium raw material, and this four bight of square tube just in time is positive stressed when carrying out the punch process distortion later stage.Be exactly in addition; Between per share aluminium raw material and the aluminium raw material in the mould of uniform temperature; Under certain external force effect, though from the physical arrangement aspect of macroscopic view, they are well to be combined as a whole; But from the physical arrangement aspect of microcosmic, their combination is that not reach the combination that kind of melt casting type far away perfect.Thereby the joint close between per share aluminium raw material and the aluminium raw material also exists in being extruded the square tube of moulding.Therefore, square tube received under the external force effect in later stage during punch process, and the force part will inevitably crackle, slight crack occur along joint close.
The utility model content
The purpose of the utility model is to address the above problem; A kind of technological prejudice that has overcome this area simply, dexterously is provided; The square tube of producing can not be cracked when post-production is used, help guaranteeing the improvement fillet aluminum alloy square tube extrusion die of square tube quality.
The technical scheme of the utility model is achieved in that
A kind of improvement fillet aluminum alloy square tube extrusion die; Comprise patrix and counterdie; Wherein make four aluminiums that are distribution symmetrically on the patrix and clamp-on the hole; Also make the square core rod of fillet at these four middle parts of clamp-oning the hole; Said counterdie has been made fillet square tube extrusion cavities accordingly, and its characteristics are that four fillets and four Kong Xincheng that clamp-on the hole of said square core rod are symmetrical set, four filleted corners of said extrusion cavities are also corresponding be arranged to identical with the orientation of four fillets of square core rod.
On the basis of aforementioned schemes; In order to improve the quality of the aluminum alloy square tube of being produced further; After aluminum alloy square tube is produced, need not carry out the polishing in later stage, just have the surface of dead smooth, light; Also made the seam chamber between above-mentioned patrix and the counterdie, the preferred height H of this seam chamber is 30mm-60mm.
The technique effect of the utility model:
The utility model is through overcome the technological prejudice of this area simply, dexterously; Four fillets and four hole hearts of clamp-oning the hole of the square core rod of extrusion die are symmetrically arranged structure; Simultaneously also with the also corresponding identical structure of being arranged to four fillets of square core rod in orientation of four filleted corners of extrusion cavities; Make square tube when extrusion modling, clamp-on four strands of aluminium raw materials that the hole enters into mould from four, joint close has been transferred to four sides of square tube simply, dexterously between per share aluminium raw material and the aluminium raw material; And this four side is in the punching press deformation processing in later stage; Just be in the stressed position of non-positive facial disfigurement, being in stress deformation position, front is four bights of square tube, thereby just can guarantee that square tube is 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.
Below in conjunction with accompanying drawing the utility model is further described:

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 make the square core rod 12 of fillet 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 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.
On the basis of aforementioned schemes; In order to improve the quality of the aluminum alloy square tube produced further, aluminum alloy square tube is produced after, need not carry out the polishing in later stage; The surface that just has dead smooth, light; As shown in Figure 1, also made seam chamber 13 between said 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; Improve 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 enterprise production and management 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.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 further to promote again the space of seam chamber 13 with this; Further increase the pressure of the aluminium raw material extruding that is squeezed in the mould again, promote the quality of product.
