Description
Technical field
The utility model relates to a kind of aluminum-alloy wheel production unit, i.e. a kind of wheel heat treating castings conformal support.
Background technology
Automotive wheel wheel hub mostly is aluminum alloy casting, after casting, also will, through Overheating Treatment, be commonly called as tempering.In actual production, find, through heat treated foundry goods, fraction defective is up to 4-5%.Bad reason mostly is casting deformation to transfinite.Research discovery, the major cause that causes casting deformation is that hang is unreasonable.Current thermal treatment kiln is furnished with support, the pillar for erectting in the middle of support, and the steel pipe of multiple horizontal is stretched out in both sides, and steel pipe inserts the through hole of foundry goods and foundry goods is brought into thermal treatment kiln.Because temperature in kiln is up to 540 DEG C, approach the fusing point of aluminium alloy, casting weight is larger in addition, and a steel pipe support causes foundry goods to be subject to force unbalance, must cause certain deformation.
Summary of the invention
The purpose of this utility model is to provide one and can carries aluminum-alloy wheel foundry goods and heat-treat process, and can not cause significantly deformation, significantly reduces the wheel heat treating castings conformal support of fraction defective.
Above-mentioned purpose is realized by following technical scheme: develop a kind of wheel heat treating castings conformal support, be characterized in: described support is the cube frame being formed by connecting by column and crossbeam, be provided with the bearing surface of multilayer horizontal in framework.
The plane that described bearing surface is made up of the pressure pin of branched horizontal, the distance between adjacent two bearing surfaces is greater than the axial height of wheel foundry goods.
On described bearing surface, having many transverse section is the groove of semicircle shape, and the cell wall of groove is to be less than or equal to wheel foundry goods periphery the Round Porous cambered surface that the surface of half matches, and the distance between upper and lower two-layer groove is greater than the diameter of wheel foundry goods.
The screen cloth face that described Round Porous cambered surface is porous.
The top of described many grooves is provided with partition rod branched and that recess axis is perpendicular, and the distance between adjacent two partition rods is greater than the axial width of wheel foundry goods.
Described partition rod two ends are stuck in the draw-in groove of two decks, and deck is arranged on the crossbeam of both sides.
The beneficial effects of the utility model are: the end face of wheel foundry goods or rim faces and support big area are coincide, in heat treatment process, can not there is not bad deformation because of unbalance stress, product fraction defective significantly reduces, and have simple in structure, with low cost, the feature such as easy to operate, is expected to promote rapidly in the same industry.

Embodiment
The total design of the utility model is in thermal treatment kiln, to adopt the support identical with wheel foundry goods big area to carry out support wheel foundry goods, prevents foundry goods unbalance stress, avoids distortion.Introduce two kinds of embodiment below in conjunction with accompanying drawing:
The first embodiment: as shown in Fig. 1 Fig. 2, this wheel heat treating castings conformal support is the cube frame being formed by connecting by column 1 and crossbeam 2, is provided with the bearing surface 3 of multilayer horizontal in framework.The form of bearing surface 3 can have multiple, and this example only exemplifies one wherein.The plane that this bearing surface 3 is made up of the pressure pin 4 of branched horizontal, the distance between two neighbouring bearing surfaces is greater than the axial height of wheel foundry goods 5.
When use, as shown in Fig. 3 Fig. 4, the end face of wheel foundry goods 5 is lain in above the pressure pin 4 of bearing surface 3, on a bearing surface 3, can place multiple wheel foundry goods 5.Foundry goods pushes whole support in thermal treatment kiln after putting again, can carry out annealing process.
Obviously, compared with the form hanging with an original steel pipe, wheel foundry goods 5 stressed areas of this mode are very large, in heat treatment process, can not deform.Contrast experiment through multiple order of classes or grades at school proves, adopts in this way, and product fraction defective drops to below 1% by original 4-5%, and economic benefit is very considerable.
The second embodiment: as shown in Fig. 5 Fig. 6, this support is also the cube frame being formed by connecting by column 1 and crossbeam 2, is provided with the bearing surface 3 of multilayer horizontal in framework.Embodiment is different from the first: on bearing surface 3, having many transverse section is the groove 6 of semicircle shape, and the cell wall of groove 6 is the Round Porous cambered surfaces 9 that match with the surface of the nearly half of periphery of wheel foundry goods 5.The Round Porous cambered surface 9 here can adopt screen cloth face.The Round Porous cambered surface 9 that also can adopt other materials to form.Vertical distance between upper and lower two-layer groove 6 Round Porous cambered surfaces 9 is greater than the diameter of wheel foundry goods 5.
When use, as shown in Fig. 7 Fig. 8, the both sides end face of wheel foundry goods 5 is erect and is put into groove 6, and wheel rim and the groove 6 of wheel foundry goods 5 nearly half match, stressed more even, there will not be bad deformation in heat treatment process.In the case of the dimensional precision of groove is higher, the out of roundness error that even also can correct wheel foundry goods 5.
The mode that wheel foundry goods 5 enters groove 6 has multiple, for example enter from rolling in the middle of groove 6, because of wheel foundry goods compared with wide can not arrival slot at the bottom of, be equivalent to carry on foundry goods, gap is left in foundry goods and groove both sides suitable for reading, to the torsion of specified location appropriateness.Also can above the crossbeam 2 between two grooves 6, push, slip into groove 6 to specified location.In order to prevent that wheel foundry goods 5 from colliding mutually, the top of groove 6 is provided with partition rod 7 branched and that groove 6 axis are perpendicular, distance between adjacent two partition rods 7 is greater than the axial width of wheel foundry goods 5, partition rod 7 can not fixed, also can be at the crossbeam of both sides 2 installed cassettes 8, deck 8 has draw-in groove above, and partition rod 7 two ends are stuck in the draw-in groove of two decks 8, can prevent that like this wheel foundry goods from colliding mutually, also can prevent that wheel foundry goods from coming off.
Contrast experiment through multiple order of classes or grades at school proves, adopts in this way, and product fraction defective drops to 0.5% by original 4-5%, and economic benefit is very considerable.
