Abstract
The utility model discloses the hammer head of hammer crusher of a kind of improvement, it includes hammer body and hammer handle, and described hammer handle is welded by connecting rod and the sleeve pipe being positioned at two ends；Described hammer body is integral with two ends sleeve pipe castingin；Described hammer end facial contour is octagon, and inscribed circle or the circumscribed circle center of circle of this octagon are concentric with collar aperture.Owing to using said structure, not only make the impact force action line acting on hammer body can be essentially by the sleeve pipe center of circle being equivalent to center of impact, reduce vibration and noise, Extending Rotor bearing service life, and avoid the phenomenon of hammer body fracture, can safety turn around use, compare with single pin-and-hole tup, postpone service life one times.
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 hammer body and hammer handle, described hammer handle is welded by connecting rod and the sleeve pipe being positioned at two ends；Described hammer body and two ends sleeve pipe edge
Cast solid；Described hammer end facial contour is octagon, and the inscribed circle of this octagon or the circumscribed circle center of circle are same with collar aperture
The heart.
Further, the cross section of described connecting rod is rectangle.
Further, the thickness of described connecting rod is less than or equal to the length of sleeve pipe.
Further, the length of described sleeve pipe and the thickness of hammer body are equal.
Further, the wall thickness of described sleeve pipe is between 10～20mm.
The beneficial effects of the utility model are: owing to using said structure, not only make the impact masterpiece acting on hammer body
Vibration and noise can be reduced essentially by being equivalent to the sleeve pipe center of circle of center of impact with line, Extending Rotor bearing service life,
And avoid hammer body fracture phenomenon, can safety turn around use, compare with single pin-and-hole tup, postpone service life one
Times.The hammer body of tup uses potassium steel, and work surface has enough wearabilities, and the shank of tup uses medium carbon steel, has foot
Enough obdurabilities, reach coordinate good with toughness of hardness, overcome homogenous material and make the shortcoming of tup, improve material profit
By rate.
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 hammer body 1 and hammer handle, described hammer handle is by connecting rod 3 He
The sleeve pipe 2 being positioned at two ends is welded；Described hammer body 1 is integral with two ends sleeve pipe 2 castingin；Described hammer body 1 end profile is just
Octagon, inscribed circle or the circumscribed circle center of circle of this octagon are concentric with sleeve pipe 2 hole.The cross section of described connecting rod 3 is rectangle,
Bigger moment of flexure can be born.According to structural requirement, the thickness of described connecting rod 3 is less than or equal to the length of sleeve pipe, described sleeve pipe 2
Length equal with the thickness of hammer body 1.Being learnt by calculating, in order to ensure the intensity of sleeve pipe 2, the wall thickness of sleeve pipe 2 is 10～20mm
Between.
Hammer body 1 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.Connecting rod
3 and sleeve pipe 2 select intensity high, the preferable medium carbon steel of plasticity, toughness, both are welded.Hammer handle after welding puts into disappearance
In mould, pouring 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.
