Abstract
The utility model discloses the hammer head of hammer crusher of a kind of improvement, it includes double end suspension ring and hammer body, described double end suspension ring are generally aligned in the same plane by round bar and two ends and the annulus that is parallel to each other is forged to one, and described hammer body is with potassium steel as matrix, by integral for two ends annulus castingin；Described hammer end facial contour is circular, and the center of circle of this circle is concentric with annulus.Owing to using said structure, make the impact force action line acting on hammer body can reduce vibration and noise essentially by being equivalent to the annulus center of circle of center of impact, Extending Rotor bearing service life.The phenomenon that hammer body will can be avoided in annulus castingin to potassium steel matrix to rupture, compares with single pin-and-hole tup, postpones service life one times.The size reference standard part lifting bolt design of double end suspension ring, by the manufacturer production of production lifting bolt, so greatly reduces manufacturing cost.
Description
Technical field
This utility model relates to the hammer head of hammer crusher of a kind of improvement.
Background technology
Currently available technology hammer head of hammer crusher one end is pin-and-hole, on the hinged bearing pin being suspended on rotor block, and the other end
Hitting Ore as tup, when tup may wear to a certain degree, i.e. entirety is scrapped, general potassium steel tup only has several service life
My god, waste is serious, and stock utilization is low.Patent No. 200520115486.X, entitled " a kind of hammer head of hammer crusher "
Utility model patent disclose a kind of can the tup that uses of double end, two ends are provided with pin-and-hole, can turn around to use another after the abrasion of one end
End, can extend one times service life in theory, but this tup problems with occurs on probation: owing to tup is whole by potassium steel
Body casting forms, and high manganese steel material hardness is high, poor toughness, gradually wears out with the scope of attack of Ore collision, the most ring-type hammer
Body wall thickness is thinning, is easy to fracture under greater impact power effect, and the tup after fragmentation enters between rotor block and screen cloth, can lead
Cause parts destroy, and cause security incident.
Summary of the invention
This utility model is in order to solve the problems referred to above, it is provided that the hammer head of hammer crusher of a kind of improvement.
This utility model solves its technical problem and be the technical scheme is that the hammer head of hammer crusher of a kind of improvement,
Including double end suspension ring and hammer body, described double end suspension ring are generally aligned in the same plane by round bar and two ends and the annulus that is parallel to each other is forged to
Integrally, described hammer body is with potassium steel as matrix, by integral for two ends annulus castingin；Described hammer end facial contour is circular, this circle
The center of circle of shape is concentric with annulus.
The beneficial effects of the utility model are: owing to using said structure, make the impact force action line acting on hammer body
Vibration and noise can be reduced, Extending Rotor bearing service life essentially by being equivalent to the annulus center of circle of center of impact.Will circle
Ring castingin, to the phenomenon that hammer body can be avoided in potassium steel matrix to rupture, is compared with single pin-and-hole tup, postpones service life one
Times.The size reference standard part lifting bolt design of double end suspension ring, by the manufacturer production of production lifting bolt, so greatly reduces
Manufacturing cost.
Accompanying drawing explanation
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing is this utility model structural representation.
Detailed description of the invention
As it can be seen, the hammer head of hammer crusher of a kind of improvement, including double end suspension ring 1 and hammer body 2, described double end suspension ring 1
The annulus being generally aligned in the same plane by round bar and two ends and be parallel to each other is forged to one, and described hammer body 2, will with potassium steel as matrix
Two ends annulus castingin is integral；Described hammer body 2 end profile is circular, and the center of circle of this circle is concentric with annulus.
Hammer body 2 selects hardness high, has again the high manganese steel material of certain wearability, the chemical composition of its design potassium steel
Mass fraction: 1.16%～1.27%C, 13.06%～14.28%Mn, 0.52%～0.84%Si, 1.91%～2.43%
Cr, 0.03%～0.05%S, 0.04%～0.06%P, 0.19%～0.25%Re, 80.82%～83.09%Fe.
The size reference standard part lifting bolt design of double end suspension ring 1, by the manufacturer production of production lifting bolt, such pole
Reduce greatly manufacturing cost.Double end suspension ring material is that intensity is high, and the preferable medium carbon steel of plasticity, toughness, its coupling part round bar can
To bear bigger moment of flexure, will not fracture, after being cast in the potassium steel abrasion that annulus is peripheral, annulus will not rupture, and such double end is hung
Ring can recycle.
Putting in evaporative pattern by double end suspension ring 1, pour into a mould potassium steel solution, making both is metallurgical binding.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
