Abstract
The utility model discloses a wear-resistant hammer head. The wear-resistant hammer head comprises a hammer body and a wear-resistant hammer head, a hammer jacket, a through hole and dovetail grooves, wherein the wear-resistant hammer head mainly comprises the hammer body and the wear-resistant hammer head, a wear-resistant alloy layer is cast and embedded at one end of the hammer body to be taken as the wear-resistant hammer head, the hammer jacket and a hammer hole are distributed at the other end of the hammer body, the dovetail grooves are arranged at the top and two sides of one end, where the wear-resistant alloy layer is embedded, of the hammer body, and a through hole the direction of which is the same as that of the hammer hole of the hammer jacket is formed in the front side of the hammer head. According to the wear-resistant hammer head, the wear resistance of the hammer head can be improved, the service life of the hammer head can be prolonged by more than 10 times, time for replacing quick-wear parts is saved, and the production cost can be lowered.
Description
Technical field
The utility model belongs to the metal casting processing technique field, relates in particular to a kind of wear-resistant hammer head.
Background technology
Tup is with the vitals of disintegrating machine particularly in the mining machinery, it is a kind of part of very easy wearing and tearing, original tup is by a kind of cast steel casting, although certain wearability is arranged, but still not as antifriction alloy, if all cast tup with antifriction alloy, cost is very high, in order both to reduce cost, can increase again the wearability of tup, the ad hoc wear-resistant hammer head of counting the technical program.
The utility model content
The purpose of this utility model provides a kind of wear-resistant hammer head, it is comprised of tup and hammer body, hammer body is by the normal steel casting manufacturing, hammer body one end embedding is cast with the tup of antifriction alloy, the other end of hammer body is provided with hammer cover and hammer hole, one end top and the both sides of tup offer dovetail groove, a dovetail groove is offered at hammer body one end top, two dovetail grooves are respectively offered in two sides, hammer body embedding casting wear-resisting alloy hammer head, and this end offers and hammers the trepanning hole into shape to identical through hole, such hammehead structure, can make the wear-resistant alloy layer of casting later in conjunction with firmly, both save wear resistant alloy material, make the anti-wear performance of tup reach the effect that full hammer is antifriction alloy.
Adopt the beneficial effect of the technical program: improve the tup wearability, prolong the service life of tup more than 10 times, save the time of changing consumable accessory, reduced simultaneously production cost.
Description of drawings
Fig. 1 is the structural representation of wear-resistant hammer head.
Among the figure: 1-hammer body, 2-wear-resistant hammer head, 3-hammer cover, 4-through hole, 5-dovetail groove.
The specific embodiment
Wear-resistant hammer head described in the utility model, specific embodiment contrast accompanying drawing is described further again: its structure comprises hammer body 1, wear-resistant hammer head 2, hammer cover 3, through hole 4, dovetail groove 5, mainly formed by hammer body 1 and wear-resistant hammer head 2 two parts, cast embedding bag one deck wear-resistant alloy layer as wear-resistant hammer head 2 at an end of hammer body 1, the other end of hammer body 1 is provided with hammer cover 3 and hammer trepanning, one end inner top and the both sides of hammer body 1 embedding bag wear-resistant alloy layer offer dovetail groove 5, a dovetail groove 5 is driven on the top, two dovetail grooves 5 are respectively driven in both sides, hammer body 1 embedding casting wear-resisting alloy hammer head 2 one ends, offer one with hammer the trepanning hole into shape to identical through hole 4.
