Abstract
The utility model discloses a kind of hammer head of hammer crusher, it comprises connection handle, and the two ends of described connection handle are symmetrically arranged with hammer body, and described hammer body is the assembly of cuboid and prismatoid, is provided with connecting hole in the middle of it; In the cuboid of two described hammer bodies, both sides castingin has several abrasion-proof sticks longitudinally arranged.Because hammer handle two ends are provided with connecting hole, tup can reverse end for end to use, and service life is 2 times of single connection hole; The abrasion-proof stick that tup both sides hammer body castingin is made by carbide alloy, greatly improves wear resistence, extends tup service life; Press-fit the good protective metal shell of plasticity in connecting hole, improve the stress of impact, tup can be avoided to rupture, alleviate the wearing and tearing to bearing pin.
Description
Technical field
The utility model relates to a kind of for hammer head of hammer crusher.
Background technology
Hammer mill can be divided into directional type (rotor rotates towards a direction) and reversible (rotor can rotate towards both direction) hammer mill by rotor gyratory directions.Reversible hammer mill generally adopts the integrated symmetric formula tup cast by potassium steel, tup two sides all will be collided with material, and tup working end, because collide with material, requires high rigidity, high-wearing feature, hammer handle is because by alternating bending stress effect, require that toughness is better.And be difficult to reach this requirement with the tup of homogenous material potassium steel casting at present.
Utility model content
In order to solve prior art Problems existing, the utility model provides a kind of high strength hammer head of hammer crusher for reversible hammer mill.
The technical scheme that the utility model adopts is: a kind of hammer head of hammer crusher, comprises connection handle, and the two ends of described connection handle are symmetrically arranged with hammer body, and described hammer body is the assembly of cuboid and prismatoid, is provided with connecting hole in the middle of it; In the cuboid of two described hammer bodies, both sides castingin has several abrasion-proof sticks longitudinally arranged.
Further, described abrasion-proof stick is cylinder.
Further, the circular section diameter of described abrasion-proof stick is between 8 ~ 12mm.
Further, the length of described abrasion-proof stick is between 20 ~ 40mm.
Further, the cross section of described connection handle is rectangle.
Further, sheath is provided with in the connecting hole of described hammer body.
The beneficial effects of the utility model are: (1) is provided with connecting hole due to hammer handle two ends, and tup can reverse end for end to use, and service life is 2 times of single connection hole; (2) abrasion-proof stick that made by carbide alloy of tup both sides hammer body castingin, greatly improves wear resistence, extends tup service life; (3) press-fit the good protective metal shell of plasticity in connecting hole, improve the stress of impact, tup can be avoided to rupture, alleviate the wearing and tearing to bearing pin.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Figure is the schematic diagram of a kind of hammer head of hammer crusher of the utility model.
Detailed description of the invention
As shown in the figure, a kind of hammer head of hammer crusher, comprises connection handle 3, the two ends of connection handle 3 are symmetrically arranged with hammer body 1, hammer body 1 is the assembly of cuboid and prismatoid, and be provided with connecting hole in the middle of it, in the cuboid of two hammer bodies 1, both sides castingin has several abrasion-proof sticks 4 longitudinally arranged.Abrasion-proof stick 4 is cylinder, and circular section diameter is between 8 ~ 12mm, and length is between 20 ~ 40mm.The cross section of connection handle 3 is rectangle.Sheath 2 is provided with in the connecting hole of hammer body 1.
The material of abrasion-proof stick 4 is K30 carbide alloy, and hardness is 89-91.5HRC, impact toughness 0.019-0.059MJm
-2, bending strength 1.08-2.16Gpa, thermal conductivity factor 75.4-87.9Wm
-1k
-1, heat resisting temperature 800 DEG C, puts it in evaporative pattern, more integrated poured potassium steel solution.Sheath 2, by the good mild steel manufacture of plasticity, in press-in connecting hole, can improve the stress of hammer body connection hole, prevent fracture, also can improve the frictional behaviour with bearing pin, reduce the wearing and tearing to bearing pin.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any equivalent replacement done and improvement, all should be included within protection domain of the present utility model.
