Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
The string of Automobile flywheel waters a casting processing technology, and its step is as follows:
A, shell processed: utilize precoated sand on core shooter, make arenaceous shell 1 and lower arenaceous shell 2, belong to common process, main improve in the structure of upper arenaceous shell 1 and lower arenaceous shell 2.Shown in composition graphs 2-Fig. 4, upper arenaceous shell 1 and lower arenaceous shell 2 snap together formation two separate and with the die cavity of flywheel outline, two die cavities are symmetrical.Upper and lower arenaceous shell 1,2 is respectively arranged with cast rising head 4, and the cast rising head 4 on upper arenaceous shell 1 flows into for molten steel, and the cast rising head 4 on lower arenaceous shell 2 flows out for molten steel.Cast rising head 4 is between two die cavities and in the outer center ofthe setting of die cavity, the cast rising head 4 of upper and lower arenaceous shell 1,2 is coaxially arranged.
In the inner chamber of upper arenaceous shell 1, be provided with short slot 5 will pour into a mould rising head 4 and be communicated with two die cavities, short slot 5, in "eight" shape, ensures that the molten steel of cast can flow in two die cavities through cast rising head 4 simultaneously.Certainly, short slot 5 also can be arranged in the inner chamber of lower arenaceous shell 2.The outer wall of upper arenaceous shell 1 is provided with two symmetrical upper locating dowel 1a, the outer wall of lower arenaceous shell 2 is provided with two symmetrical lower locating dowel 1b, in upper locating dowel 1a and lower locating dowel 1b, one of them is solid, another is hollow, hollow internal diameter mates with solid external diameter, to ensure that hollow locating dowel can be inserted in solid locating dowel.Two lower locating dowel 1b are coaxially arranged with each self-corresponding upper locating dowel 1a respectively.
B, making cast gate: utilize precoated sand to make cast gate on core shooter, also belong to common process.Cast gate 3 comprises a charging aperture and a discharging opening, and charging aperture is funnel-form.
C, in tandem: as shown in Figure 1, upper arenaceous shell 1 and lower arenaceous shell 2 form one group of casting moulds, some groups of casting moulds to be together in series all through casting moulds of formation one row die cavity successively by cast rising head 4.Located by upper locating dowel 1a and lower locating dowel 1b between adjacent casting moulds, the discharging opening of cast gate 3 connects first group casting moulds.Between the discharging opening of cast gate 3 and the first cast rising head 4 organizing casting moulds, again by bonding leakproof after splicing between the cast rising head 4 of adjacent each group of casting moulds, a cast rising head 4 idle on the group casting moulds of end is sealed by plug 6, leaks to prevent molten steel.
D, string water: good casting moulds in tandem is put into the container of open top and the charging aperture ensureing cast gate 3 upward, facilitate pour steel.Pour in container by shot or shot again, whole container is placed on shake table, utilizes shake table by shot or shot jolt ramming, thus utilize shot or shot to be compressed by casting moulds, prevent casting moulds to be out of shape, ensure product quality, and ensure that the charging aperture of cast gate 3 is outside exposed.Be preferably, the micro-vibration frequency of shaking of steps d medium and low frequency is less than or equal to 15Hz, and amplitude is less than or equal to 1mm.Finally poured into from the charging aperture of cast gate 3 by the molten iron after heating and pour into a mould, molten iron is flowed in each die cavity of all casting moulds successively by the discharging opening of cast gate 3.
Cool in e, type: after casting complete, allow shot or shot, and casting moulds rests in container, utilize shot or shot to absorb the heat of casting moulds; Cool time in step e is 20 ~ 30min, and the endothermic effect of shot or shot is good, shortens half than traditional cool time.
F, knockout: by shot or shot, and casting moulds all falls from container introversion and goes out, the flywheel blank after shaping drops out in casting moulds, and dead head on flywheel blank is because of the gravity Automatic-falling of self, and the wall thickness of flywheel blank dead head is 3 ~ 4mm.
G, foundry goods cool: the flywheel blank temperature after knockout completes is still high, and flywheel blank cools naturally, is allowed for access next step, to avoid scalding workman, are also to ensure the too high damage equipment of flywheel blank temperature in subsequent technique simultaneously.
H, cleaning foundry goods: utilize shot-blast cleaning machine to clear up the scab on flywheel blank surface; Apron type airless shot blasting machine is adopted in step h.
I, machine add rear warehouse-in.
Step h and i is traditional handicraft, does not repeat them here.
The foregoing is only preferred embodiment of the present invention, is not restriction with the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
