Description
Technical field
This utility model relates to a kind of hammer head of hammer crusher.
Background technology
The tup of hammer mill is the parts directly hitting and entering crusher chamber material, and material is broken by the strike of tup
Broken.Existing one piece casting or the hammer head of hammer crusher of forging, as long as hammer body may wear to a certain degree, i.e. entirety is scrapped, material
Utilization rate is low.
Utility model content
In order to improve service life and stock utilization further, this utility model provides a kind of hammer head of hammer crusher.
This utility model solves its technical problem and be the technical scheme is that a kind of hammer head of hammer crusher, including hammer
Body, hammer handle and bolt, the top half of described hammer body spherically body structure, the latter half is circular cone structure；Described hammer body
Centrage upper end is provided with shoulder hole, and lower end is provided with round platform hole；Described hammer handle is by axis orthogonal top Rotary-table and bottom
Hollow cylinder forms, and described Rotary-table upper end diameter is little, lower end diameter big, on round platform hole, described hammer body lower end and described hammer handle
Portion's Rotary-table matches；Described hammer handle top is provided with the screwed hole coaxial with described hammer body shoulder hole along axis, in described screwed hole
Connecting and have steel-wire screw-socket, described steel-wire screw-socket is formed with the bolt through described hammer body upper end shoulder hole and threadeds；Described spiral shell
The nut of bolt is arranged below spring washer, and the top of described bolt is locked by split pin；Described hammer body uses potassium steel to be matrix,
And at spherical surface body and frustum of a cone transition position castingin rich chromium cast iron ring.
Further, described bolt is hexagon socket head cap screw.
Further, the diameter of described bolt is between 16-24mm.
Further, the cross section of described rich chromium cast iron ring is circular section.
The beneficial effects of the utility model are: after hammer body abrasion, hammer handle need not be pulled down from hammer mill bearing pin, as long as
Turn on connection hexagon socket head cap screw, thus reduce maintenance operation difficulty and time-consuming.Castingin height chromium casting on hammer body
Iron hoop, extends the service life of hammer body further.
Accompanying drawing explanation
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Figure is this utility model hammer head of hammer crusher structural representation.
In figure: spring washer 1, hammer body 2, bolt 3, steel-wire screw-socket 4, split pin 5, hammer handle 6, rich chromium cast iron ring 7.
Detailed description of the invention
As it can be seen, a kind of hammer head of hammer crusher, including hammer body 2, hammer handle 6 and bolt 3, the first half of described hammer body 2
Dividing spherically body structure, the latter half is circular cone structure；The centrage upper end of described hammer body 2 is provided with shoulder hole, and lower end is provided with
Round platform hole；Described hammer handle 6 is made up of axis orthogonal top Rotary-table and lower hollow cylinder, on described Rotary-table
End diameter is little, lower end diameter big, and round platform hole, described hammer body 2 lower end matches with described hammer handle 6 top Rotary-table；On described hammer handle 6
Portion is provided with the screwed hole coaxial with described hammer body 2 shoulder hole along axis, and connecting in described screwed hole has steel-wire screw-socket 4, described steel
Silk swivel nut 4 is formed with the bolt 3 through described hammer body 2 upper end shoulder hole threadeds；The nut of described bolt 3 is arranged below bullet
Spring packing ring 1, the top of described bolt 3 is locked by split pin 5；Described hammer body 2 uses potassium steel to be matrix, and at spherical surface body and circle
Frustum transition position castingin rich chromium cast iron ring 7.The cross section of described rich chromium cast iron ring 7 is circular section, and diameter is between 15-20mm.
Described bolt 3 is hexagon socket head cap screw.The diameter of described bolt 3 is between 16-24mm.
This utility model is the combinative structure of hammer body and hammer handle, and a combination thereof uses threaded, in order to prevent hammer handle 6 screw thread
The damage in hole, embedded in steel-wire screw-socket 4.
Steel-wire screw-socket is a kind of novel threaded fastener, be by high intensity, in high precision, the rhombus that has of any surface finish cuts
A kind of concentric body of spring-like internal and external threads that the stainless steel silk in face accurately processes.Develop for protection matrix screwed hole
Insert, is screwed in and is fastened in the screwed hole of one of connected piece, is formed and meets international standard female thread, is shaped like
In helical spring, there is higher hardness and preferable surface roughness.Be divided into plain edition and lock type two kinds, lock type be
Increase by circle or an a few circle clamp ring on the basis of medium-sized.It is low that steel-wire screw-socket embeds Al alloys andMg alloys, cast iron, fiberglass, plastics etc.
In the screwed hole of the engineering material of intensity, there is bonding strength high, antidetonation, shock resistance and anti abrasive function, can dispersive stress
Protection matrix screw thread, is greatly prolonged the service life of matrix.
By in rich chromium cast iron ring 7 castingin to hammer body 2 potassium steel matrix, the interface of castingin is metallurgical binding, the former hard
Phase M7C3 type carbide also can partly drift about and be diffused in potassium steel, makes hammer body 2 scope of attack the most wear-resisting but also impact resistance, will not
Produce fracture, given full play to the advantage of bi-material, extended service life；Use hammer body 2 and hammer handle 6 combinative structure, mill
Only change hammer body 2 after damage, and hammer handle 6 can be continuing with, and has saved material.
After hammer body 2 abrasion, hammer handle 6 need not be pulled down from hammer mill bearing pin, as long as turning on connection bolt 3,
Thus reduce maintenance operation difficulty and time-consuming.
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.
