Description
Technical field
The utility model relates to field of mechanical technique, specifically provide a kind of crushing-screening machine wear-resistant hammer head.
Background technique
The crushing-screening machine applied in the fields such as metallurgy, coal mine, chemical industry at present generallys use the high-manganese steel of good toughness
The tup of matter, for large scale material to be crushed to small size material.Tup during military service not only by impact wear, cut
Skiving damage, is also squeezed, shears and the repeated action of fatigue stress, and working condition is severe, is easily wear-out part.Therefore, tup
The necessary impact resistance of the material of selection and wear-resistant, meanwhile, the toughness and wearability for needing to have certain in hammer handle part material.
However, the hardening effect of potassium steel is bad under low impact stress, its wear-resisting property is caused to be not in full use.And it uses
Alloy steel material, tup are easy to appear fracture and chip off-falling phenomenon.
The Double-metal composite hammer developed in recent years had not only had the toughness of medium carbon low alloy steel, but also with rich chromium cast iron
Hardness and wearability.But the combination degree of bimetal hammerhead steel and iron faying face is there are no good control measure at present, makes
Occur leading to premature failure because faying face combination degree is bad often with bimetal hammerhead, serious person's tup along faying face be broken,
It falls off and flies out；During rotating broken coal, tup with coal contact surface because upper end hammer handle part thickness is weaker, and for middle carbon it is low
Steel alloy, wearability is insufficient, and premature abrasion failure often occurs here, and serious person falls off from hammer handle connecting pin, to life
Production brings security risk.

The wear-resisting property of installation position avoids rotating in shattering process in tup, the inoperative mounting portion premature abrasion with coal contact surface
Failure, high degree improve the service life and security performance of tup, can prevent the position premature breakage, and then appear in
Mounting hole nearby generates phenomena such as slight crack, rupture when operation, and then hypophysis is caused integrally to fly out, and safety accident occurs.
2, the inoperative portion mounting portion of the utility model and the combination interface of work department are using half crenation interconnecting piece knot
It closes, compared with the combination of conventional flat line, increases the contact area of two kinds of metals, greatly improve bond strength.
And semicircle transition angle uses fillet, compared with dovetail shaped combination, will not generate stress in transitional region and concentrate, ensure that hammer
Head when in use will not be chipping because of internal stress.
3, rod iron is placed in the inside of the inoperative portion mounting portion of the utility model and work department, on the one hand can be used as lacing wire
Increase bond strength；Another aspect rod iron can play the effect of internal densener, i.e., when being poured hammer head material, keep hammer head material fast
Fast, uniform cooling, the generation for the defects of reducing internal porosity, shrinkage cavity, simultaneously as cooling rate increases, tup rich chromium cast iron material
Phenomena such as material internal grain is refined, promotes its service performance, avoid the occurrence of chip off-falling, fragmentation, prolongs the service life.Rod iron
The safety effectively guaranteed in use process is set, reduces use cost, reaches efficient good comprehensive benefit.
4, the work department of the utility model is designed as trapezoidal block, and is equipped with groove in bottom, can be further improved brokenly
Broken efficiency extends the service life of tup.
