Abstract
A combined mold for casting a ultra-large double-row centering roller bearing holder rough barrel comprises casting water drums, a sand box, a soleplate, upper core iron, lower core iron, a casting rough barrel and a casting water gap. Both the upper core iron and the lower core iron are respectively and relatively machined into an obliquity about 5.17 DEG, the sand box is arranged on the soleplate, the inside of the sand box is produced into a casting rough barrel sand mold, and two sides of the casting rough barrel sand mold are respectively provided with a bottom inverse-casting water gap. The upper core iron and the lower core iron, which are pre-heated to 200 DEG C before the casting, are combined together to be placed inside the casting rough barrel sand mold. The two casting water drums are simultaneously filled with molten copper, the molten copper is inversely cast into the casting rough barrel from the bottom of the casting water gap, after the molten copper is solidified, the upper core iron, the lower core iron and the sand box are opened, and the holder rough barrel is molded in a casting way. Due to adopting the combined mold, the potential danger that insecurity exists when the holder rough barrel is cast in a centrifugal way can be avoided, convenience, safety and reliability in manual operation can be realized; and the core iron can be used for multiple times, so that economy can be achieved.
Description
Technical field
The utility model relates to bearing parts manufacturing technology field, particularly relates to a kind of super-huge double-row self-aligning roller bearing retainer hair cylinder sand casting combination mold.
Background technology
Present super-huge double-row self-aligning roller bearing extensively model is used for cement machinery and mine mechanism; wherein a part of cement machinery and mine mechanism rotating ratio are higher; load also larger; during the large load operation of the high rotating speed of super-huge double-row self-aligning roller bearing; easily produce moment unbalance loading phenomenon; stressed difference during the work of two row rollers, retainer easily weares and teares and breaks down, and causes equipment downtime to safeguard.Therefore, select there are three kinds for the retainer material of design bearing; (brass. steel. spheroidal graphite cast-iron .), brass material has superior property, example: 232/850CA retainer material is selected brass material, size and weight for the super-huge retainer hair cylinder size that weighs wide series, the hair cylinder is cast with difficulty by mechanical centrifugal, because its about 1.8 tons ranges of work that exceed centrifugal machine of hair cylinder weight are all dangerous for equipment and the person.
The utility model content
The technical problems to be solved in the utility model is that a kind of easy to operate and safe and reliable super-huge double-row self-aligning roller bearing retainer hair cylinder sand casting combination mold is provided.
The technical scheme that adopts is:
A kind of super-huge double-row self-aligning roller bearing retainer hair cylinder casting combination mold comprises casting water bag, sandbox, base plate, upper core iron, lower core iron, casting hair cylinder, the casting mouth of a river.Described upper core iron all becomes 10 minutes gradient of 5 degree with respect to car with lower core iron, puts sandbox on the base plate, makes casting hair cylinder sand mold in its sandbox, and casting hair cylinder sand mold both sides are respectively equipped with the uphill running casting mouth of a river, the end.The upper core iron of 200 ℃ of preheatings before the casting and lower core iron combined be placed in the middle of the casting hair cylinder sand mold, form retainer hair cylinder sand casting combination mold.
The utility model can be avoided retainer hair cylinder mechanical centrifugal casting hidden danger, and operation is very easy and safe and reliable for the workman, and core iron can repeatedly use, and is economical and practical.

The specific embodiment
A kind of super-huge double-row self-aligning roller bearing retainer hair cylinder casting combination mold comprises casting water bag 5, sandbox 6, base plate 7, upper core iron 1, lower core iron 2, casting hair cylinder 3, the casting mouth of a river 4.Described upper core iron 1 all becomes 10 minutes gradient (seeing Fig. 2, Fig. 3) of 5 degree with respect to car with lower core iron 2.Put sandbox 6 on the base plate 7, make casting hair cylinder 3 sand molds in its sandbox 6, casting hair cylinder 3 sand mold both sides are respectively equipped with the anti-casting mouth of a river 4, the end.The upper core iron 1 of 200 ℃ of preheatings before the casting and lower core iron 2 combined be placed in the middle of the casting hair cylinder sand mold, two casting water bags 5 water copper water simultaneously, the copper water anti-copper water that makes progress from casting 4 bottoms, the mouth of a river is cast into casting hair cylinder 3, core iron and sandbox are opened retainer hair cylinder casting about after solidifying.A kind of super-huge double-row self-aligning roller bearing retainer hair cylinder casting combination mold of described formation.
