Abstract
The utility model discloses a tup, it includes hammer block and hammer handle for hammer crusher the hammer block be table form, be equipped with the little round thru hole of big, the middle diameter of both ends diameter on its central line, circle thru hole lower extreme matches with hammer handle upper portion hollow bar excircle, and the hollow bar hole matches with the cylindric lock that passes hammer block circle thru hole, hammer block excircle middle part has the cross section to be square rich chromium cast iron wear ring along the circumference castingin. The rich chromium cast iron is the 3rd take the place of wear -resistant material behind the hard IV cast iron of potassium steel and nickel, and its hardness can reach 60HRC, forms the higher M7C3 type carbide of microhardness in its tissue easily, and the interface of castingin is metallurgical bonding, and the former stereoplasm looks M7C3 type carbide still can partly drift about and spread potassium steel, and messenger's hammer block scope of attack is not only wear -resisting but also shock -resistant, can not produce the fracture, full play the advantage of two kinds of materials, life has prolonged more than 3 times.
Description
Technical field
The utility model relates to a kind of tup for hammer mill.
Background technology
The tup of hammer mill directly hits the critical component entering crusher chamber ore, requires that first the structural design of tup should meet collision equilibrium condition, then have higher service life and stock utilization.
Because hammer head of hammer crusher is hingedly suspended on the bearing pin of rotor block, when tup hits ore, the tup point of impingement will act on impulsive force.Known by rational mechanics, if impulsive force is by center of impact, then bearing pin colliding counter-force is zero; If impulsive force is not by center of impact, then impulsive force can produce collision counter-force on the bearing pin of rotor block.
Because the prior art hammer head of hammer crusher hammer body scope of attack is generally rectangle or trapezoidal; because the every bit of the scope of attack all likely implements the strike to material; impact force action line usually can depart from the center of impact of setting; cause on bearing pin, produce collision counter-force; its consequence produces detrimental resistance square; shorten rotor bearing service life, even can damage bearing pin.
Li Zhengfeng is at patent of invention " hammer head of hammer crusher " (patent No. ZL200910001666.8) disclosed a kind of tup be assembled by hammer body and hammer handle, wherein hammer body is billiard table shape, it can meet the equilibrium condition of collision completely, hammer body uniform wear can be ensured again, extend service life.Hammer body adopts the potassium steel of homogenous material, although have good toughness, surface can be made to produce work hardening phenomenon, increase substantially its case hardness under the effect of greater impact power.But the impact be subject to due to some material broken is strong, and the work hardening ability that potassium steel has can not fully be played, therefore show quick abrasion, service life short weakness.
Summary of the invention
In order to improve service life further, improve stock utilization, a kind of tup for hammer mill that the utility model provides, meeting on existing advantage basis, extends service life again further.
The utility model solves the technical scheme that its technical problem adopts: a kind of hammer head of hammer crusher, comprise hammer body and hammer handle, described hammer body is billiard table shape, it is large that its center line is provided with two ends diameter, the round open-work that mid diameter is little, described round open-work lower end and hammer handle upper hollow shaft cylindrical match, and hollow stem endoporus and the straight pin through hammer body circle open-work match, described hammer body (1) and straight pin (3) are by bolt (7), channel nut (6) and split pin (5) are fixed, in the middle part of described hammer body cylindrical, circumferentially castingin has cross section to be square wear ring.
Further, the described wear ring square-section length of side is 12-20mm.
The beneficial effects of the utility model are: castingin rich chromium cast iron wear ring in the potassium steel matrix of tup hammer body.Rich chromium cast iron be after potassium steel and the hard IV cast iron of nickel the 3rd generation high-abrasive material, its hardness can reach 60HRC, the higher M7C3 type carbide of microhardness is easily formed in its tissue, the quantity of the type carbide is larger, its wearability is better, but there is the defect such as cast difficulty, poor impact toughness, easily fracture in overall rich chromium cast iron tup, to such an extent as to its use is restricted.Wear ring castingin is made into in potassium steel matrix with rich chromium cast iron, the interface of castingin is metallurgical binding, the former hard phase M7C3 type carbide also partly can drift about and be diffused in potassium steel, make the hammer body scope of attack not only wear-resisting but also shock-resistant, fracture can not be produced, give full play to the advantage of bi-material, extend more than 3 times service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing is the utility model hammer head of hammer crusher structural representation.
Detailed description of the invention
As shown in the figure, the utility model hammer head of hammer crusher comprises hammer body 1 and hammer handle 4, described hammer body 1 is in billiard table shape, its center line is provided with the round open-work that two ends diameter is large, mid diameter is little, described round open-work lower end and hammer handle 4 upper hollow shaft cylindrical match, and hollow stem endoporus and the straight pin 3 through hammer body 1 circle open-work match, described hammer body 1 is fixed by bolt 7, channel nut 6 and split pin 5 with straight pin 3, and in the middle part of described hammer body 1 cylindrical, circumferentially castingin has cross section to be square wear ring 2.The described wear ring 2 square-section length of side is 12-20mm.Wear ring 2 is made up of rich chromium cast iron.Rich chromium cast iron be after potassium steel and the hard IV cast iron of nickel the 3rd generation high-abrasive material, its hardness can reach 60HRC, the higher M7C3 type carbide of microhardness is easily formed in its tissue, the quantity of the type carbide is larger, its wearability is better, but there is the defect such as cast difficulty, poor impact toughness, easily fracture in overall rich chromium cast iron tup, to such an extent as to its use is restricted.Wear ring castingin is made into in potassium steel matrix with rich chromium cast iron, the interface of castingin is metallurgical binding, the former hard phase M7C3 type carbide also partly can drift about and be diffused in potassium steel, make the hammer body scope of attack not only wear-resisting but also shock-resistant, fracture can not be produced, give full play to the advantage of bi-material, extend more than 3 times service life.
When changing consumable accessory hammer body 1, hammer handle 4 need not be pulled down from rotor bearing pin, as long as back out split pin 5, screws off channel nut 6, extracts bolt 7 out, and then extracts straight pin 3 out and can unload lower hammer 1.Channel nut 6 is standard component, with split pin 5 conbined usage, and can be effectively locking.
Claims (2)
1. a hammer head of hammer crusher, comprise hammer body (1) and hammer handle (4), described hammer body (1) is in billiard table shape, it is large that its center line is provided with two ends diameter, the round open-work that mid diameter is little, described round open-work lower end and hammer handle (4) upper hollow shaft cylindrical match, and hollow stem endoporus and the straight pin (3) through hammer body (1) circle open-work match, described hammer body (1) and straight pin (3) are by bolt (7), channel nut (6) and split pin (5) are fixed, it is characterized in that in the middle part of described hammer body (1) cylindrical, circumferentially castingin has cross section to be square wear ring (2).
