Abstract
The utility model relates to a device for centrifugal casting of a roller shell, belonging to the technical field of casting equipment; the device is used for reducing the casting cost of the roller shell of a roller press or a vertical roller mill. According to the technical scheme, an upper cover of the device is blocked at the upper part of a cold type, and a bottom plate of the device is blocked at the lower end of the cold type; a cylindrical lower inner sleeve is arranged between the bottom plate and the upper cover; the outer wall of the lower inner sleeve is closely matched with the inner wall of the cold type, and the shape of the inner wall of the lower inner sleeve is matched with that of the outer wall of a workpiece to be cast; a cylindrical upper inner sleeve is arranged above the upper cover; the outer wall of the upper inner sleeve is closely matched with the inner wall of the cold type; the upper inner sleeve is fixed with the cold type by a locating pin. The inner sleeve is additionally arranged into the cold type, so that only the proper lower inner sleeve is needed to be replaced when the cylindrical or conical roller shells with different circumference shapes and different specifications are cast, and the cold type is not needed to be replaced; the working excircle is not needed to be processed, so that the production cost of the roller shell is greatly lowered. The device is simple in structure, convenient to use and good in effect, has remarkable economic benefit, and can be popularized and applied in the industry.
Description
Technical field
The utility model relates to a kind of device that adopts vertical centrifugal-casting machine to produce the roller shell of different circumference profiles, belongs to Casting Equipment technical field.
Background technology
In the time using vertical centrifugal-casting machine to produce workpiece, centrifugal casting outer surface of workpiece has various shapes, if the profile of foundry goods is circular, and can be by casting cold mould directly to shape molding, if the profile of foundry goods is other shapes, just need to be realized by machined after casting.Use the roller sleeve of roller press of vertical centrifugal-casting machine production and the profile of vertical grinder roller shell to be circle, can directly use cold mould moulding.But, because roller sleeve of roller press appearance has the fin of axially spaced-apart, vertical grinder roller shell appearance is conical, two kinds all belong to special-shaped workpiece, general employing is directly made into by cold mould the shape matching with roller shell profile, and because specification is more, need to make multiple cold moulds, greatly increase production cost.Therefore the device of, developing a kind of roller shell of centrifugal casting is cheaply very necessary.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device of centrifugal casting roller shell, and this device can reduce the casting cost of roller sleeve of roller press, vertical grinder roller shell.
The technical scheme solving the problems of the technologies described above is:
A kind of device of centrifugal casting roller shell, its formation comprises cast cover plate, ground cover plate, centrifugal basket, cold mould, upper cover, base plate, centrifugal basket base, upper cover shutoff is on cold mould top, base plate shutoff is in cold mould lower end, its improvements are, columnar lower inner sleeve is set between base plate and upper cover, the outer wall of lower inner sleeve and the inwall of cold mould closely cooperate, the inner wall shape of lower inner sleeve matches with workpiece outer wall to be cast, above upper cover, there iing inner sleeve in cylindrical shape, the outer wall of upper inner sleeve and the inwall of cold mould closely cooperate, upper inner sleeve is fixed by alignment pin and cold mould.
The device of above-mentioned centrifugal casting roller shell, the inwall circumferential shapes of described lower inner sleeve and the peripheral shape of roller sleeve of roller press match.
The device of above-mentioned centrifugal casting roller shell, the inwall circumferential shapes of described lower inner sleeve and the peripheral shape of vertical grinder roller shell match.
The beneficial effects of the utility model are:
The utility model has been set up inner sleeve in cold mould, in the time of the different circumferential shapes of casting, the cylindrical shape of different size, conical roller shell, only need to change suitable lower inner sleeve, and cold mould is without replacing, and work cylindrical, without processing, so just greatly reduces the production cost of roller shell.The utility model is simple in structure, easy to use, respond well, has significant economic benefit, can in industry apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
In figure, mark is as follows: cast cover plate 1, ground cover plate 2, upper inner sleeve 3, centrifugal basket 4, cold mould 5, upper cover 6, lower inner sleeve 7, base plate 8, alignment pin 9, centrifugal basket base 10.
The specific embodiment
The utility model forms by pouring into a mould cover plate 1, ground cover plate 2, upper inner sleeve 3, centrifugal basket 4, cold mould 5, upper cover 6, lower inner sleeve 7, base plate 8, alignment pin 9, centrifugal basket base 10, upper cover 6 shutoff on cold mould 5 tops, base plate 8 shutoff are in cold mould 5 lower ends, upper inner sleeve 3 and lower inner sleeve 7 are parts that the utility model increases in existing centrifugal casting structure.
Fig. 1 or 2 demonstrations, lower inner sleeve 7 is arranged between base plate 8 and upper cover 6, and the inwall of the outer wall of lower inner sleeve 7 and cold mould 5 closely cooperates, and the inner wall shape of lower inner sleeve 7 matches with workpiece outer wall to be cast.
Fig. 1 or 2 demonstrations have inner sleeve 3 in cylindrical shape above upper cover 6, and the inwall of the outer wall of upper inner sleeve 3 and cold mould 5 closely cooperates, and upper inner sleeve 3 is fixing with cold mould 5 by alignment pin 9.Upper inner sleeve 3 is used in conjunction with lower inner sleeve 7, and the height of upper inner sleeve 3 is determined according to the height of lower inner sleeve 7.
In Fig. 1, show, in the time producing roller sleeve of roller press, the inwall circumferential shapes of lower inner sleeve 7 and the peripheral shape of roller sleeve of roller press match.Roller sleeve of roller press cylindrical fin, in the time making the roller shell of different size, only needs lower inner sleeve 7 adjust according to roller sleeve of roller press profile, and adjusts the height of upper inner sleeve 3, guarantee like this work off-type after cylindrical need not process.
In Fig. 2, show, in the time producing vertical grinder roller shell, the inwall circumferential shapes of lower inner sleeve 7 and the peripheral shape of vertical grinder roller shell match.In the time making the vertical grinder roller shell of different size, only need lower inner sleeve 7 adjust according to vertical grinder roller shell profile, and adjust the height of upper inner sleeve 3, guarantee like this work off-type after cylindrical need not process.
Production process of the present utility model is:
First, base plate 8 and cold mould 5 are installed, be fixed with alignment pin 9, then lower inner sleeve 7 is packed in cold mould 5, after upper cover 6 is installed, after upper inner sleeve 3 is in place, be fixed with alignment pin 9.Frock is carried out being installed in centrifuge after preheating, spray paint, matches with the boss of centrifugal basket base 10 in the bottom of base plate 8, and cold mould 5 matches with centrifugal basket 4, will pour into a mould cover plate 1 and cover on ground cover plate 2, puts gate spool and gets final product etc. to be cast.
