Abstract
The invention relates to the axle manufacturing industry. A driving axle housing feeding technology is characterized in that when pouring and feeding are carried out by utilizing iron liquids, an axle housing is only provided with a high heating dead head. Metal easily cut sheets are adopted for the high heating dead head, and the dead head is knocked off, and surface residue of a cast element is less; the cleaning and grinding working amount is lowered; the iron liquid utilization ratio and the technology product yield are improved; and the production cost is saved.
Description
Technical field
The present invention relates to the vehicle bridge manufacturing industry, relate generally to a kind of axle housing processing technology.
Background technology
At present, cold riser feeding technique is mainly adopted in the production of domestic driving axle housing, for guaranteeing Internal Quality of Cast, internal flaw do not occur, and general cold rising head setting is all larger, and the molten iron utilization rate is low.Use cold rising head that axle housing is carried out feeding, quantity is more and the rising head volume is larger because rising head is offered, and dead head is removed difficulty, needs 8 minutes by one case running gate system of equipment cleaning.Pouring technology adopts molten iron to enter side riser by running channel, then enters the foundry goods die cavity by riser neck foundry goods is carried out feeding, and cold rising head utilization rate only has about 15%.
Summary of the invention
In order to solve the existing problem of background technology, the present invention has adopted following technical scheme: a kind of driving axle housing feeding technology is only offered a high hot riser on axle housing when utilizing molten iron to water feeding.
Above-mentioned high hot riser is opened in the fixed point position that axle housing easily produces defective.
The intensity of high exothermic riser own is high, put and be applicable to flexibly various formative technologies, solving in the past high pressure moulding can not directly place rising head because rising head intensity is low and get defective in moulding, high exothermic riser adopts the metal cameron core, the abate rising head is residual little at cast(ing) surface, reduce cleaning polishing workload, improved molten iron utilization rate, product yield, saved production cost.
Specific embodiment
Use cold rising head that axle housing is carried out feeding, because rising head offers that quantity is more and the rising head volume is larger, dead head is removed difficulty, needs 8 minutes by one case running gate system of equipment cleaning, adopt high exothermic riser after, remove running gate system and only need 3 minutes.Use common cold rising head that axle housing is carried out feeding, former running gate system weight about 137kg, molten iron utilization rate 62.3%, and after using high exothermic riser, running gate system no longer is provided with cold rising head and is directly introduced by ingate, running gate system weight 39kg, molten iron utilization rate 85.5%.Use high exothermic riser, avoided owing to using cold rising head to prick drop, cinder hole defective that steam vent causes; The fixed point feeding has guaranteed the inherent quality of axle housing.
The intensity of high exothermic riser own is high, puts to be applicable to flexibly various formative technologies, solves in the past high pressure moulding and can not directly place rising head in moulding because rising head intensity is low and get defective; Use high exothermic riser to adopt the metal cameron core, the abate rising head is residual little at cast(ing) surface, has reduced cleaning polishing workload; Use high exothermic riser, improved molten iron utilization rate, product yield, saved production cost.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
Claims (2)
