Abstract
The utility model discloses a kind of pillow of the powder metallurgy forming for steelmaking feed, is two spherical crown cylinder pillows, the spherical crown section at column body segment and its two ends in the middle of comprising, the equal diameters of column body segment and spherical crown section.Above-mentioned shape of the present utility model can guarantee that the make peace contact surface area that falls with any direction of the weight one of each pillow is consistent, thereby all directions stressed that guarantee pillow are made peace, intensity is consistent, make each pillow broken probability that jumps identical, guarantee security when steel mill feeds intake.Solved prior art because of pillow outside surface be plane while causing falling because the contact surface area of different landing grounds is different, cause its stressed difference different with intensity,, while finally causing steel mill to feed intake, there is the defect of potential safety hazard in the probability difference that makes pillow jump broken.
Description
Technical field
The utility model relates to a kind of powder metallurgy forming part, is specifically related to a kind of shape of the pillow of the powder metallurgy forming for steelmaking feed.
Background technology
The mould molding that each manufacturer is used at present pillow is out generally rectangular parallelepiped, cubes or prismatic body, when above-mentioned pillow all cannot guarantee that it falls, the surface-area of landing instant contact is consistent, can not guarantee stressed consistent, can not proof strength consistent, cannot assess intensity, also just cannot guarantee the broken probability that jumps identical when pillow falls, make steelworks when feeding intake, have potential safety hazard.
Utility model content
The purpose of this utility model lands while being to provide a kind of falling that area is consistent, stressed consistent, the moulding pillow that intensity is consistent of all directions, the potential safety hazard when overcoming steelworks and feeding intake.
This pillow of the powder metallurgy forming for steelmaking feed that the utility model provides is two spherical crown cylinder pillows, the spherical crown section at column body segment and its two ends in the middle of comprising.
The equal diameters of described column body segment and spherical crown section.
Above-mentioned shape of the present utility model can guarantee the weight one of each pillow make peace while falling with any direction surface area consistent, thereby all directions stressed that guarantee pillow are made peace, intensity is consistent, make each pillow broken probability that jumps identical, guarantee security when steel mill feeds intake.Solved prior art because of pillow outside surface be plane while causing falling because the contact surface area of different landing grounds is different, cause its stressed difference different with intensity,, while finally causing steel mill to feed intake, there is the defect of potential safety hazard in the probability difference that makes pillow jump broken.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, this pillow of the powder metallurgy forming for steelmaking feed that the utility model provides, the spherical crown section 2 at column body segment 1 and its two ends in the middle of comprising.The equal diameters of column body segment 1 and spherical crown section 2.
Moulding pillow outside surface of the present utility model is the circular arc camber that bending radius is consistent, can guarantee that contact area when each pillow lands is consistent, thereby guarantee that the stressed intensity consistent, each pillow of all directions is consistent, make each pillow broken probability that jumps identical, guarantee security when steel mill feeds intake.Solved prior art because of pillow outside surface be plane while causing falling because the contact area of different landing grounds is different, cause its stressed difference different with intensity,, while finally causing steel mill to feed intake, there is the defect of potential safety hazard in the probability difference that makes pillow jump broken.
Claims (2)
1. the pillow of the powder metallurgy forming for steelmaking feed, is characterized in that: this pillow is two spherical crown cylinder pillows, the spherical crown section at column body segment and its two ends in the middle of comprising.
2. the pillow of the powder metallurgy forming for steelmaking feed as claimed in claim 1, is characterized in that: the equal diameters of described column body segment and spherical crown section.
