Abstract
The utility model discloses the hammer head of hammer crusher of a kind of improvement, including hammer body and hammer handle, the top half of described hammer body spherically body structure, the latter half is circular cone structure；Described hammer handle is made up of the orthogonal upper cylinder of axis and lower hollow cylinder；Described hammer body is with potassium steel as matrix, and at spherical surface body and frustum of a cone transition position castingin rich chromium cast iron ring；Described hammer handle upper cylinder castingin is in described hammer body lower cone platform.By in rich chromium cast iron ring castingin to hammer body 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, make the hammer body scope of attack the most wear-resisting but also impact resistance, fracture will not be produced, give full play to the advantage of bi-material, extend service life；And the shank of tup uses medium carbon steel, there is enough intensity and toughness, reach coordinate good with toughness of hardness, overcome the shortcoming that homogenous material makes tup.
Description
Technical field
This utility model relates to the hammer head of hammer crusher of a kind of improvement.
Background technology
Currently, in broken industry, using substance at the medium and small tup of 150-350N, shared ratio is higher, reaches 60%
Above.Solve the material of such tup and forming method problem, and the installation of tup and the problem of replacing, it is that broken industry is badly in need of
The difficult problem solved.Existing one piece casting or the hammer head of hammer crusher of forging, hardness and toughness can not good match, service life
Short, stock utilization is low.
Utility model content
In order to improve service life and stock utilization further, this utility model provides the hammer mill of a kind of improvement
Tup.
This utility model solves its technical problem and be the technical scheme is that the hammer head of hammer crusher of a kind of improvement,
Including hammer body and hammer handle, the top half of described hammer body spherically body structure, the latter half is circular cone structure；Described hammer handle by
The orthogonal upper cylinder of axis and lower hollow cylinder composition；Described hammer body is with potassium steel as matrix, and at sphere
Body and frustum of a cone transition position castingin rich chromium cast iron ring；Described hammer handle upper cylinder castingin is in described hammer body lower cone platform.
Further, the cross section of described rich chromium cast iron ring is square.
Further, the cross section length of side of described rich chromium cast iron ring is between 20-30mm.
The beneficial effects of the utility model are: by rich chromium cast iron ring castingin to hammer body potassium steel matrix, the interface of castingin
In metallurgical binding, the former hard phase M7C3 type carbide also can partly drift about and be diffused in potassium steel, makes hammer body hit
Face is the most wear-resisting but also impact resistance, will not produce fracture, give full play to the advantage of bi-material, extended service life；And tup
Shank use medium carbon steel, there is enough intensity and toughness, reach coordinate good with toughness of hardness, overcome homogenous material
The shortcoming making tup, improves stock utilization.
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 this utility model structural representation.
Detailed description of the invention
As it can be seen, the hammer head of hammer crusher of a kind of improvement, including hammer body 1 and hammer handle 3, the first half of described hammer body 1
Dividing spherically body structure, the latter half is circular cone structure；Described hammer handle 3 is by the orthogonal upper cylinder of axis and bottom
Hollow cylinder forms；Described hammer body 1 is with potassium steel as matrix, and at spherical surface body and frustum of a cone transition position castingin rich chromium cast iron ring
2；Described hammer handle 3 upper cylinder castingin is in described hammer body 1 lower cone platform.The cross section side of being of described rich chromium cast iron ring 2
Shape.The cross section length of side of described rich chromium cast iron ring 2 is between 20-30mm.
The diameter of described hammer handle 3 upper cylinder is between 20-40mm.The described hammer handle 3 cylindrical endoporus of lower hollow
Diameter is between 40-60mm.
Hammer body 1 selects plasticity, toughness preferable, has again the high manganese steel material of certain wearability, the change of its design potassium steel
The mass fraction studied point: 1.16%～1.27%C, 13.06%～14.28%Mn, 0.52%～0.84%Si, 1.91%～
2.43%Cr, 0.03%～0.05%S, 0.04%～0.06%P, 0.19%～0.25%Re, 80.82%～83.09%Fe.
Hammer handle 2 selects intensity high, and the preferable medium carbon steel of plasticity, toughness, such as 45 steel.By rich chromium cast iron ring 2 castingin to hammer body 1 high-manganese steel-base
In body, the interface of castingin is metallurgical binding, and the former hard phase M7C3 type carbide also can partly drift about and be diffused into Gao Meng
In steel, make hammer body 1 scope of attack the most wear-resisting but also impact resistance, fracture will not be produced, given full play to the advantage of bi-material, extended
Service life.
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.
