Abstract
The utility model discloses the hammer head of hammer crusher of a kind of improvement, it includes hammer body and hammer handle, described hammer handle is welded by connecting rod and the sleeve pipe being positioned at two ends, and described sleeve pipe cylindrical is also welded with several hard alloy bars, and described hard alloy bar radially distributes；Described hard alloy bar is coniform, and its microcephaly welds with sleeve pipe；Described hammer body is integral with two ends sleeve pipe castingin；Described hammer end facial contour is circular, and the center of circle of this circle is 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.The hammer body of castingin hardness alloy rod, its wearability is greatly improved, and about service life is three times of potassium steel, and is more suitable for crash high temperature material.
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, and described sleeve pipe cylindrical is also welded with
Several hard alloy bars, described hard alloy bar radially distributes；Described hard alloy bar is coniform, its microcephaly and set
Sealing of tube；Described hammer body is integral with two ends sleeve pipe castingin；Described hammer end facial contour is circular, the center of circle of this circle and sleeve pipe
Hole is concentric.
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；The hammer body of castingin hardness alloy rod, its wearability has obtained greatly
Raising, about service life are three times of potassium steel, and are more suitable for crash high temperature material.
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, and described sleeve pipe 2 cylindrical is also welded with several hard alloy bars 4, described hard alloy bar
4 radially distribute；Described hard alloy bar 4 is coniform, and its microcephaly welds with sleeve pipe 2；Described hammer body 1 and two ends sleeve pipe 2
Castingin is integral；Described hammer body 1 end profile is circular, and the center of circle of this circle is concentric with sleeve pipe 2 hole.The horizontal stroke of described connecting rod 3
Cross section is rectangle, can bear bigger moment of flexure.According to structural requirement, the thickness of described connecting rod 3 is less than or equal to the length of sleeve pipe
Degree, the length of described sleeve pipe 2 is equal with the thickness of hammer body 1.Learnt by calculating, in order to ensure the intensity of sleeve pipe 2, the wall of sleeve pipe 2
Thick between 10～20mm.
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.
The one that hard alloy is made up by powder metallurgical technique of hard compounds and the binding metal of refractory metal
Alloy material.Hard alloy has a series of premium properties such as hardness is high, intensity is good, wear-resisting, heat-resisting, corrosion-resistant, particularly it
High rigidity and wearability, even if being also held essentially constant at a temperature of 500 DEG C, still have the highest hardness when 1000 DEG C.
The hammer body 1 of imbedding hard alloy bars substantially increases hardness and heat resistance, is more suitable for crash high temperature material.
Connecting rod 3 and sleeve pipe 2 select intensity high, and both are welded by the preferable medium carbon steel of plasticity, toughness.After welding
Hammer handle put in evaporative pattern, 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.
