Abstract
The invention discloses a kind of reversible formula hammer head of hammer crusher, it includes the inner ring and outer ring for the rolling bearing being distributed on circumference, and castingin potassium steel between the outer ring and inner ring, the outer ring is coated with the hammer body using potassium steel as matrix；The hammer body end profile is circle, and the circular center of circle and inner ring are concentric；Three hammer bodies are linked together by the gusset also using potassium steel as matrix, and the outer profile of the gusset is circular curve, and tangent with hammer body.Using the bearing that potassium steel is waste and old as castingin in the hammer body of matrix, the phenomenon that hammer body is broken not only was effectively prevented, but also extend service life；The waste and old bearing of castingin greatly reduces manufacturing cost, meets the theory of circular economy；Three inner rings all can be used as pin hole and are hinged with rotor block axis pin, and when for reversible hammer mill, hammer body both sides can all hit ore, service life quite extends six times, greatly reduces use cost, improve economic benefit.
Description
Technical field
The present invention relates to a kind of reversible formula hammer head of hammer crusher.
Background technology
Reversible hammer mill be lime stone fine crushing in the industrial departments such as metallurgy, building materials, chemical industry and water power, coal or other
One of the capital equipment of the following brittle material of medium hardness.It is big with reduction ratio, production capacity is high, advanced structure, dependable performance,
Stable working, the features such as low energy consumption and epigranular.Hammer mill is divided to two kinds of reversible and unidirectional type, reversible hammer broken
The rotor of broken machine is reversible, is generally used for fine crushing；The rotor of unidirectional type hammer mill is irreversible, broken in being generally used for.Machine
In use for some time, what tup worked has worn out on one side, and the liner plate and grid section of rotor side also have certain abrasion, this
When can stop a motor reversal connection, at this moment rotor reverses, and tup is unworn to reform into working face on one side, and utilizes the other side
Unworn grid section and liner plate.Tup of installation can two sides use, reduce the set-up time, improve working efficiency.
Currently available technology hammer head of hammer crusher one end is pin hole, is hingedly suspended on the axis pin of rotor block, the other end
Ore is hit as tup, when tup is worn to a certain extent, i.e., whole to scrap, stock utilization is low.
Invention content
The present invention to solve the above-mentioned problems, provides a kind of reversible formula hammer head of hammer crusher.
The technical solution adopted by the present invention to solve the technical problems is：A kind of reversible formula hammer head of hammer crusher,
Inner ring and outer ring including being distributed in the rolling bearing on circumference, castingin potassium steel between the outer ring and inner ring, the outer ring
It is coated with the hammer body using potassium steel as matrix；The hammer body end profile is circle, and the circular center of circle and inner ring are concentric；It is described
Three hammer bodies are linked together by gusset also using potassium steel as matrix, and the outer profile of the gusset is circular curve, and with hammer body phase
It cuts.
Further, the thickness of the gusset is less than the thickness of hammer body.
Further, the thickness of the hammer body is equal to the thickness of outer ring.
Further, the wall thickness of the inner ring is between 10~15mm.
The beneficial effects of the invention are as follows：It can be with due to, making to act on using the above structure impact force action line on hammer body
Essentially by the bearing inner race center of circle for being equivalent to center of impact, vibration and noise, Extending Rotor bearing service life are reduced；With height
Manganese steel is the bearing that castingin is waste and old in the hammer body of matrix, has not only effectively prevented the phenomenon that hammer body is broken, but also extend service life；
The waste and old bearing of castingin greatly reduces manufacturing cost, meets the theory of circular economy；Three inner rings all can be used as pin hole and rotor
Body axis pin is hinged, and when for reversible hammer mill, hammer body both sides can all hit ore, service life quite extends six
Times, use cost is greatly reduced, economic benefit is improved.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the sectional view of Figure 1A-A.
Specific implementation mode
As depicted in figs. 1 and 2, a kind of reversible formula hammer head of hammer crusher, including the axis of rolling that is distributed on circumference
The inner ring 2 held and outer ring 3, castingin potassium steel between the outer ring 3 and inner ring 2, the outer ring 3 is coated with using potassium steel as matrix
Hammer body 1；1 end profile of the hammer body is circle, and the circular center of circle and inner ring 2 are concentric；The gusset 4 is also with potassium steel
Three hammer bodies 1 are linked together by matrix, and the outer profile of the gusset 4 is circular curve, and tangent with hammer body 1.
For the ease of casting, the thickness of the gusset 4 is less than the thickness of hammer body 1, and the thickness of the hammer body 1 is equal to outer ring 3
Thickness.
For proof strength requirement, the wall thickness of the inner ring 2 is between 10~15mm.
Hammer body 1 selects hardness high, and the high manganese steel material with certain wearability, designs the chemical composition of 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.
Outer ring and inner ring are waste and old bearing, are put into evaporative pattern after removing cleaning, and potassium steel solution is poured into a mould, both make be in
Metallurgical binding.
Bearing steel has high and uniform hardness and wearability and high elastic limit, and it is wear-resisting tup can be greatly improved
Property, improve service life.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
