Abstract
The utility model discloses the lithotrite quartering hammer of a kind of improvement, it includes that hammer body, hammer handle and straight pin, described hammer handle upper end are to set round-meshed Rotary-table on axis, and lower end is hollow disk；Described hammer body is combined into one by upper hemispherical body and bottom Rotary-table: described hammer body is with potassium steel as matrix, and the edge's circumferentially castingin combined at hemisphere and Rotary-table has several bearing steel spheroids；Described hammer body centrage upper end is shoulder hole, and lower end is round platform hole, and round platform hole matches with hammer body lower end Rotary-table；Described straight pin matches through hammer body upper end shoulder hole with hammer handle upper end circular hole, and lower end is locked by split pin.By high intensity, high rigidity bearing steel spheroid castingin in tup potassium steel matrix, make the tup scope of attack the most wear-resisting but also impact resistance, extend service life；Use hammer body and hammer handle combinative structure, only change hammer body after abrasion, and hammer handle can be continuing with, and has saved material.
Description
Technical field
This utility model relates to the lithotrite quartering hammer of a kind of improvement.
Background technology
Lithotrite is the disintegrating apparatus that mine is conventional, by it, big lump ore ore reduction is become fritter Ore, is contained in rotor
Quartering hammer on body clashes into Ore, is allowed to broken.Existing quartering hammer uses the potassium steel of homogenous material, when broken hardness is the highest
During Ore, impact is not strong, and the work hardening ability that potassium steel has can not fully be played, and therefore shows
The weakness that quick abrasion, service life are short, and after wearing and tearing, whole quartering hammer is scrapped, and waste is serious.
Summary of the invention
In order to improve service life further, improving stock utilization, this utility model provides the lithotrite of a kind of improvement
Quartering hammer.
This utility model solves its technical problem and be the technical scheme is that the lithotrite quartering hammer of a kind of improvement, bag
Including hammer body, hammer handle and straight pin, described hammer handle upper end is to set round-meshed Rotary-table on axis, and lower end is hollow disk；Described
Hammer body is combined into one by upper hemispherical body and bottom Rotary-table；Described hammer body is with potassium steel as matrix, at hemisphere and round platform
Edge's circumferentially castingin that body combines has several bearing steel spheroids；Described hammer body centrage upper end is shoulder hole, and lower end is
Round platform hole, and round platform hole matches with hammer body lower end Rotary-table；Described straight pin is through hammer body upper end shoulder hole and hammer handle upper end circle
Hole matches, and lower end is locked by split pin.
Further, the round end face of described straight pin and hammer body hole end surface contact position are provided with faced washer.
Further, the diameter of described straight pin is between 20-30mm.
Further, the diameter of described split pin is between 12-16mm.
Further, the diameter of described bearing steel spheroid is between 20-30mm.
The beneficial effects of the utility model are: by high intensity, high rigidity bearing steel spheroid castingin to tup high-manganese steel-base
In body, make the tup scope of attack the most wear-resisting but also impact resistance, extend service life；Use hammer body and hammer handle combinative structure, after abrasion
Only change hammer body, and hammer handle can be continuing with, save material.Use lost foam casting hammer body, it is possible to reduce percent defective, maximum
The raising stock utilization of limit.
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 the lithotrite quartering hammer structural representation of a kind of improvement of this utility model.
Detailed description of the invention
As it can be seen, the lithotrite quartering hammer of a kind of improvement, including hammer body 2, hammer handle 5 and straight pin 3, on described hammer handle 5
End is for setting round-meshed Rotary-table on axis, and lower end is hollow disk；Described hammer body 2 is by upper hemispherical body and bottom Rotary-table group
Integrator；Described hammer body 2 is with potassium steel as matrix, and the edge's circumferentially castingin combined at hemisphere and Rotary-table has some
Individual bearing steel spheroid 6；Described hammer body 2 centrage upper end is shoulder hole, and lower end is round platform hole, and round platform hole is round with hammer body 2 lower end
Stage body matches；Described straight pin 3 matches through hammer body 2 upper end shoulder hole with hammer handle 5 upper end circular hole, and lower end is locked by split pin 4.
The round end face of described straight pin 3 and hammer body 2 hole end surface contact position are provided with faced washer 1.The diameter of described straight pin 3
Between 20-30mm.The diameter of described split pin 4 is between 12-16mm.The diameter of described bearing steel spheroid 6 20-30mm it
Between.
The spheroid using bearing steel manufacture is used on rolling bearing, has the advantages such as intensity is good, hardness is high, wearability is good,
Common used material has GCr15, GCr15SiMn etc., and after heat treatment, hardness is generally 60-65HRC.Owing to being standard component, can be in market
Directly buy, or the spheroid in waste and old rolling bearing is pulled down recycle.By in its castingin to potassium steel matrix, hammer body is made to beat
Face of hitting is the most wear-resisting but also impact resistance, has given full play to the advantage of bi-material, has extended more than 2 times service life.Use evaporative pattern
Casting hammer body, it is possible to reduce percent defective, improves stock utilization to greatest extent.
When changing consumable accessory hammer body 2, hammer handle 5 need not be pulled down from rotor bearing pin, as long as backing out split pin 4, extracts cylinder out
Pin 3, can unload lower hammer 2.
