Abstract
The utility model discloses a kind of composite material ring hammer crusher ring hammers, it includes hammer body, the hammer body center is equipped with hexagon ring, the hammer body outer ring surface, which corresponds to, is provided with dovetail groove at hexagon, the dovetail groove bottom edge is provided with the circle open-work perpendicular to hexagon, castingin wear body in the dovetail groove and circle open-work.Since hammer body material is intensity and the higher middle carbon cast steel of hardness with certain toughness and plasticity, and bore design is increased into hammer body intensity at hexagon ring, hammer body fracture can be effectively prevented.Hexagon ring can also effectively avoid the Relative sliding generated after ring hammer collision and beat phenomenon, crushing effect from being better than existing top fuller.Hexagon interior angle at random hingedly hits material with pin shaft, is equipped with trapezoidal hole in 6 scopes of attack, the wear body of castingin rich chromium cast iron material, improves wearability, extend its service life in hole.
Description
Technical field
The utility model relates to a kind of composite material ring hammer crusher ring hammers.
Background technique
Ring hammer crusher be it is a kind of with ring hammer impact rotor formula crusher, after material enters crusher, first by
It is crushed to being acted on the high-speed rotating ring hammering blow of rotor, pulverized material obtains kinetic energy simultaneously from ring hammer, at high speed
Ground rushes at crushing shell, is crushed for the second time, then falls on sieve plate, shearing, extruding, grinding and the material hammered into shape by ring
Mutual collision between material is further crushed, and is discharged through sieve pore.Ring hammer is mostly annular shape, also known as top fuller at present.
Ring hammer material mostly use potassium steel ZGMnl3 or other wear-resisting alloy steels, when outer ring surface wear to a certain extent it is necessary to replace, it is no
It is then broken because cross-sectional area becomes smaller, ring hammer service life is shorter, and waste of material is serious.In addition, top fuller is inserted in rotor
On body pin shaft, due to the effect of centrifugal force, top fuller is thrown away outward, formed strike torque, but with material collision after, top fuller inner ring surface
Relative sliding is generated with pin shaft, beat phenomenon occurs, influences strike effect.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of composite material ring hammer crusher ring hammers.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of composite material ring hammer crusher ring
Hammer, including hammer body, the hammer body center are equipped with Hexagon hole, are provided with dovetail groove at the corresponding interior hexagon of the hammer body outer ring surface,
The dovetail groove bottom edge is parallel to interior hexagon, the dovetail groove top margin camber line and the same arc of outer ring surface, the center of the dovetail groove
Line is the perpendicular bisector of interior hexagon, and round open-work is provided between dovetail groove bottom edge and interior hexagon；In the dovetail groove and
Casting rich chromium cast iron forms wear body in circle open-work.
Further, the wear body and hammer body uniform thickness.
Further, the top margin of the dovetail groove is greater than bottom edge.
Further, the diameter of the round open-work changes between 25-40mm.
The utility model has the beneficial effects that since hammer body material is with certain toughness and plasticity, intensity and hardness
Higher middle carbon cast steel, and bore design is increased into hammer body intensity at hexagon ring, hammer body fracture can be effectively prevented.Hexagonal
Hole can also effectively slow down the Relative sliding generated after ring hammer collision and beat phenomenon, crushing effect are better than existing top fuller.Hexagonal
Hole interior angle is hinged with pin shaft at random, in trapezoidal hole the rich chromium cast iron material of castingin wear body formed 6 scopes of attack to material into
Row strike, improves wearability, extends its service life.
Detailed description of the invention
With reference to the accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the utility model section schematic diagram.
Fig. 2 is the utility model and material impacting schematic diagram.
Specific embodiment
As shown in Figure 1, a kind of composite material ring hammer crusher ring hammer, including hammer body 1,1 center of hammer body are equipped with interior
Hexagon ring, 1 outer ring surface of hammer body correspond to and are provided with dovetail groove at interior hexagon, and the dovetail groove bottom edge is parallel to interior hexagon,
The dovetail groove top margin camber line and the same arc of outer ring surface, the center line of the dovetail groove is the perpendicular bisector of interior hexagon, in ladder
Round open-work 11 is provided between shape slot bottom side and interior hexagon；The casting rich chromium cast iron shape in the dovetail groove and circle open-work 11 of hammer body 1
At wear body 2.The wear body 2 and 1 uniform thickness of hammer body.The top margin of the dovetail groove is greater than bottom edge.The diameter of the round open-work 11
It is changed between 25-40mm.
Since hammer body material is intensity and the higher middle carbon cast steel of hardness with certain toughness and plasticity, and by inner hole
It is designed to hexagon ring, increases hammer body intensity, hammer body fracture can be effectively prevented.Six interior angles of hexagon ring in rotary course with
Machine is hinged with pin shaft, and the wear body of the rich chromium cast iron material of castingin forms 6 scopes of attack and hits material in trapezoidal hole, mentions
High wearability.
Rich chromium cast iron is the 3rd generation wear-resistant material after potassium steel and the hard IV cast iron of nickel, its hardness can reach 60HRC,
The higher M7C3 type carbide of microhardness easy to form in its tissue, the quantity of the type carbide is bigger, and wearability is got over
It is good, but entirety is cast with rich chromium cast iron, there is the defects of casting difficulty, poor impact toughness, be easily broken off, so that it makes
With being restricted.By in rich chromium cast iron castingin to hammer body dovetail groove, the interface of castingin is in metallurgical bonding, and dovetail groove bottom edge is opened
There is the circle open-work perpendicular to hexagon, rich chromium cast iron solution is right with the metallurgical junction of hammer body into wherein, further increasing, and will not take off
It falls and is broken.
As shown in Fig. 2, the hexagon ring interior angle of the utility model is rotated around pin shaft, it is equivalent to and pin shaft is put into dovetail groove
In, effectively slow down beat phenomenon, crushing effect is better than existing top fuller.
