Abstract
The utility model discloses a kind of composite material coal breaker peening hammer, including strike body, hammer handle and hammer ring, the hammer handle upper end and strike body castingin are integral, and the strike body is cylindrical or round table-like is arranged and coaxial with hammer handle；The hammer handle lower end and hammer ring are integrally welded；The hammer ring is in hollow discoid setting, axis of the axis for hammering ring into shape perpendicular to hammer handle.By on rich chromium cast iron solution-cast to hammer handle, the cylindric or round table-like scope of attack is formed, keeps strike body i.e. wear-resisting and impact resistance, extends 3 times or more than homogenous material potassium steel service life.The utility model has given full play to the advantage of two kinds of materials, improves stock utilization to greatest extent.
Description
Technical field
The utility model relates to a kind of composite material coal breaker peening hammers.
Background technique
Coal breaker is a kind of commonly used equipment of coal mine, and bulk coal is broken into fritter coal by it, on rotor block
Peening hammer and coal hit, be allowed to broken.Existing peening hammer uses the potassium steel of homogenous material, is subject to due to broken coal
Impact is not strong, and the work hardening ability that potassium steel has cannot be played sufficiently, therefore show quick abrasion, using the longevity
Short weakness is ordered, and entire peening hammer is scrapped after abrasion, waste is serious.
Summary of the invention
In order to further increase service life, stock utilization is improved, the utility model provides a kind of composite material broken coal
Machine peening hammer.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of composite material coal breaker peening hammer,
Including strike body, hammer handle and hammer ring, the hammer handle upper end with hit that body castingin is integral, and the strike body is cylindrical or rotary table
Shape setting and it is coaxial with hammer handle；The hammer handle lower end and hammer ring are integrally welded；The hammer ring is in hollow discoid setting, described
Hammer axis of the axis perpendicular to hammer handle of ring into shape.
Further, the hammer handle insertion hits intracorporal depth greater than 50mm.
Further, the hammer handle upper end, which intersects, is provided with 2 circle open-works perpendicular to hammer handle axis.
The beneficial effects of the utility model are: being formed on rich chromium cast iron solution-cast to hammer handle cylindric or round table-like
The scope of attack, make to hit that body is i.e. wear-resisting and impact resistance, extend 3 times or more than homogenous material potassium steel service life.On hammer handle
End, which intersects, is provided with 2 circle open-works perpendicular to hammer handle axis, is equivalent to two pin shafts of insertion, increases the metallurgical bonding with hammer handle
Degree, will not fall off and be broken.Hammer handle can be made of the steel shaft of coal mine waste, and bending strength is high, will not fracture.Hammering ring into shape can be by waste and old
Steel plate production, save the cost.The utility model has given full play to the advantage of two kinds of materials, improves material use to greatest extent
Rate.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Attached drawing 1 is a kind of coal breaker peening hammer structural schematic diagram of the utility model.
Specific embodiment
As shown, a kind of composite material coal breaker peening hammer, including strike body 1, hammer handle 2 and hammer ring 3, the hammer handle 2
Upper end and strike 1 castingin of body it is integral, the strike body 1 it is cylindrical or it is round table-like be arranged and it is coaxial with hammer handle 2；The hammer handle
2 lower ends and hammer ring 3 are integrally welded；The hammer ring 3 is in hollow discoid setting, and the axis of the hammer ring 3 is perpendicular to hammer handle 2
Axis.
The insertion of hammer handle 2 hits intracorporal depth and is greater than 50mm.2 upper end of hammer handle, which intersects, is provided with 2 perpendicular to hammer
The circle open-work of arbor line.
This in a circular table shape or columned strike shape reduces rejection rate convenient for casting.
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 peening hammer is integrally cast with rich chromium cast iron, there is the defects of casting difficulty, poor impact toughness, be easily broken off, so that
Its use is restricted.By on hammer handle made of rich chromium cast iron castingin to steel shaft, the interface of castingin is in metallurgical bonding, makes to hit
Face is not only wear-resisting but also impact resistance, extends 3 times or more than homogenous material potassium steel service life.Intracorporal depth is hit in hammer handle insertion
Greater than 50mm, and hammer handle upper end intersection is provided with 2 circle open-works perpendicular to hammer handle axis, is equivalent to two pin shafts of insertion, has
Effect increases right with the metallurgical junction of hammer handle, will not fall off and is broken.Hammer handle can be made of the steel shaft of coal mine waste, bending strength
Height will not fracture.Hammer ring can be made by waste and old steel plate, save the cost.The utility model has given full play to the advantage of two kinds of materials,
Stock utilization is improved to greatest extent.
