Abstract
The utility model discloses a centrifugal casting tool for a roller ring of a perforating machine. The centrifugal casting tool includes a conical barrel-shaped cold forming device, as well as an upper end cover and a lower end cover which are made of gray cast iron, take the shapes of circular plates and are arranged at the two ends of the conical barrel of the cold forming device, wherein a casting hole for centrifugal casting is formed at the center of the upper end cover; annular support platforms matched with the outer diameters of the upper end cover and the lower end cover respectively are arranged at the two ends of the cold forming device; pins are arranged on the inner side of the support platform at the parts having the thickness corresponding to the thicknesses of the upper end cover and the lower end cover; and footings used for fixing centrifugal equipment is arranged at the lower end of the cold forming device. The centrifugal casting tool for the roller ring of the perforating machine has a reasonable structure, and with respect to the use, the product produced through the centrifugal casting tool has the characteristics of low manufacturing cost, small casting defect on the roller face, high density and excellent mechanical property.
Description
Technical field
The utility model relates to a kind of frock of using when carrying out metal casting, specifically is employed frock when casting the punch collars with centrifugation technique.
Background technology
The punch collars is the critical component that makes rolled piece produce plastic deformation and obtain the ideal design shape, also is the parts of lot of consumption during steel rolling is produced, and requires its top layer to have good wearability and red hardness usually.So the quality of its quality directly influences the quality of rolled piece.But in the prior art, forging or static casting are generally adopted in the production of punch collars, and the forging production cost is high, and nipping property of milling train is poor; Casting flaw is many on the collars roll surface of static casting, and this will directly influence the surface quality of rolled piece.In order to solve the deficiency of above-mentioned two kinds of casting methods, the applicant proposes to use the idea of centrifugation technique casting punch collars, but does not also have corresponding centrifugal casting frock at present.On the one hand this frock should guarantee the quality of centrifugal casting, makes the crystal grain on surface of punch collars of centrifugal casting enough meticulous, has certain wearability; To be convenient to following process when on the other hand, also will keep certain surplus; At last, this frock can also play the processing of the centre bore of being convenient to the punch collars through certain designed.
The utility model content
The utility model technical issues that need to address provide a kind of employed frock when being used for centrifugal casting punch collars.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The punch collars is used the centrifugal casting frock; Comprise the circular cone tubular cold mould, be arranged on the circular tabular upper end cover and the bottom end cover of casting pig material at the circular cone tube two ends of cold mould; The center of upper end cover is provided with the plug hole of centrifugal casting; Said cold mould two ends are provided with the annular brace table that cooperates with the external diameter of upper end cover and bottom end cover respectively, are provided with pin in the brace table inboard with upper end cover, the corresponding position of bottom end cover thickness, and the lower end setting of said cold mould and centrifugation apparatus be the footing of usefulness fixedly.
The further improvement of the utility model is: the side setting circular groove corresponding with foundry goods of said upper end cover, the corresponding foundry goods of bottom end cover; Lay the high-temperature-resistant layer of being filled by high-temperature material in the circular groove, the center of the high-temperature-resistant layer of bottom end cover also is provided with the round boss corresponding with the centre bore of punch collars.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model has designed and has been exclusively used in the frock that the centrifugal casting of punch collars is used, and not only production cost is low to use centrifugation technique casting punch collars, and the product roll surface casting flaw of manufacturing is few, serviceability is good.The utility model does not adopt and the on all four cold mould of punch collars shape, but cold mould is approximated to the awl tubular structure, and the molten steel during cast in the centrifugal frock solidifies under the acting in conjunction of centrifugal force and metal mold cooling; Field trash in the molten steel in the centrifugal frock moves to the internal layer of molten steel, and finally solidifies at internal layer under action of centrifugal force; The casting flaw of the punch collars of being produced is few; The roll surface of punch collars has the tiny chill crystal grain of the cold mould cooling generation of metal, and the density of product is high, improves the wearability of punch collars greatly; The hair that reduces the punch collars only than, also guaranteeing simultaneously has certain surplus to be convenient to processing.Upper end cover and the bottom end cover of the utility model design all are provided with high-temperature-resistant layer, prevent the burn into damage to frock of molten iron and the molten steel of high-temperature.
To sum up, the utility model is rational in infrastructure, the use aspect, and the product of being produced has that production cost is low, roll surface casting flaw is few, density is high, the characteristics of good mechanical property.

Wherein, 1, upper end cover, 2, bottom end cover, 3, cold mould, 4, pin, 5, high-temperature-resistant layer, 6, boss, 7, punch collars product, 8, punch collars product blank, 9, the platform of centrifugation apparatus.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is explained further details:
The punch collars is used the centrifugal casting frock, and is as depicted in figs. 1 and 2, comprises cold mould 3, upper end cover 1, bottom end cover 2.Said cold mould 3 is cone barrel shapes, and upper end cover 1 and bottom end cover 2 are the circular platy structure that cooperates with the two ends of the circular cone tube of cold mould, and upper end cover 1 all adopts the making of casting pig material with bottom end cover 2, and the center of upper end cover 1 is provided with plug hole.On the circumference of the madial wall at cold mould 3 two ends the annular brace table is set, the external diameter and the annular brace table of upper end cover 1 and bottom end cover 2 match each other.The madial wall of annular brace table is on the sidewall of cold mould and is uniformly distributed with some pin-and-holes with upper end cover 1, the corresponding position of bottom end cover 2 thickness, and upper end cover is fixedly connected with cold mould 3 with the pin 4 of bottom end cover through No. 45 steel.The lower end setting of said cold mould 3 and centrifugation apparatus be the footing of usefulness fixedly.One side of said upper end cover, the corresponding foundry goods of bottom end cover is provided with circular groove; The size of circular groove is corresponding with the size of foundry goods; Be provided with by high-temperature material in the circular groove and fill the high-temperature-resistant layer of laying 5, the center of the high-temperature-resistant layer of bottom end cover also is provided with the round boss corresponding with the centre bore of punch collars 6.Add man-hour; The punch collars of centrifugation apparatus rotation drive top is with the rotation of centrifugal casting frock, and molten steel gets into from the plug hole of upper end cover 1, and molten steel solidifies under the acting in conjunction of the cold mould cooling of centrifugal force that rotates at a high speed and metal; Final formation product as shown in Figure 3; Remove allowance in the following process again, institute's product processed density is than higher, and anti-wear performance is good.
