Abstract
The utility model discloses a kind of hammer head of hammer crusher, including three suspension ring and hammer body, described three suspension ring include three uniform annulus being generally aligned in the same plane, and three annulus are connected as a single entity by connecting rod；Described hammer body is with potassium steel as matrix, respectively by integral for three annulus castingins；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；Using three suspension ring, each suspension ring when for reversible hammer mill, Ore all can be hit in hammer body both sides, can quite extend six times as pin-and-hole and rotor block hinge its service life.
Description
Technical field
This utility model relates to a kind of hammer head of hammer crusher.
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.Additionally tup two uses, and its function does not give full play to.
Summary of the invention
This utility model is in order to solve the problems referred to above, it is provided that a kind of hammer head of hammer crusher.
This utility model solves its technical problem and be the technical scheme is that a kind of hammer head of hammer crusher, including three
Head suspension ring and hammer body, described three suspension ring include three uniform annulus being generally aligned in the same plane, and three annulus are by connecting rod even
It is integrated；Described hammer body is with potassium steel as matrix, respectively by integral for three annulus castingins；Described hammer end facial contour is circle
Shape, the center of circle of this circle is concentric with annulus.
Further, the cross section of described connecting rod is circular.
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 is to the phenomenon that hammer body can be avoided in potassium steel matrix to rupture；Using three suspension ring, each suspension ring can be as pin-and-hole
With rotor block hinge, when for reversible hammer mill, Ore all can be hit in hammer body both sides, and its service life is suitable
Extend six times.The size reference standard part lifting bolt design of three suspension ring, by the manufacturer production of production lifting bolt, such pole
Reduce greatly 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, a kind of hammer head of hammer crusher, including three suspension ring 1 and hammer body 2, described three suspension ring 1 include three
The individual uniform annulus being generally aligned in the same plane, three annulus are connected as a single entity by connecting rod；The cross section of described connecting rod is circular.
Described hammer body 2 is with potassium steel as matrix, respectively by integral for three annulus castingins；Described hammer body 2 end profile is circular, this circle
The center of circle of shape 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 three suspension ring 1, by the manufacturer production of production lifting bolt, such pole
Reduce greatly manufacturing cost.Three suspension ring materials are that intensity is high, and the preferable medium carbon steel of plasticity, toughness, its connecting rod can be born
Bigger moment of flexure, will not fracture, and after the potassium steel abrasion that annulus is peripheral, annulus will not rupture, and such three suspension ring can circulate and make
With.
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.
Claims (2)
1. a hammer head of hammer crusher, it is characterised in that: include that three suspension ring and hammer body, described three suspension ring include three positions
In conplane uniform annulus, three annulus are connected as a single entity by connecting rod；Described hammer body, with potassium steel as matrix, respectively will
Three annulus castingins are integral；Described hammer end facial contour is circular, and the center of circle of this circle is concentric with annulus.
A kind of hammer head of hammer crusher the most according to claim 1, it is characterised in that: the cross section of described connecting rod is circle
Shape.
