Abstract
The utility model discloses a hammer head of a hammer crusher, which comprises a hammer body, wherein a groove is lengthways formed at the top of the hammer body; the groove is divided into two separate half segments; and abrasion resistant bodies are welded in the groove. Therefore, welding firmness can be enhanced. After one surface of the hammer head is abraded, the other surface of the hammer head can be used by turning the hammer head, and after the hammer head is abraded to a certain extent, build-up welding can be conducted on the hammer head again, so that the service life of the hammer head is greatly prolonged; and besides, the hammer body is formed by casting or forging middle or low carbon steel, and has the advantages of good tenacity and less possibility of fracture.
Description
Technical field
The utility model relates to a kind of tup that is used for hammer mill.
Background technology
At present, the material that is applied to hammer head of hammer crusher in the industrial production is potassium steel ZGMnl3, but in, under the low impact wear situation, it impacts the transformation hardening ability and can not give full play to, it is lower to show as wearability, service life is shorter, the existing in addition bimetallic composite hammer head of reporting, during hammer handle adopts, mild steel, the tup wearing part is a rich chromium cast iron, can give full play to carbon steel good toughness, non-frangibility, rich chromium cast iron hardness height, the advantage that wearability is good, but exist rich chromium cast iron that the danger that comes off along faying face takes place easily, jeopardize device security.
Summary of the invention
The utility model provides a kind of hammer head of hammer crusher at the deficiencies in the prior art, and its wearing part is formed by the wear resistance electrode built-up welding, to prolong the service life of tup.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hammer head of hammer crusher, comprise hammer body, and wherein the hammer body top longitudinally is provided with groove, and described groove cuts off in the centre, forms separately two sections, is welded with wear body in the groove.
Further, described wear body thickness is between 15～30mm.
Further, described hammer body shank is provided with round open-work.
The beneficial effects of the utility model are, because the tup top has groove, build-up wear-resistant welding rod in the groove can increase the firmness of welding, behind this tup one surface wear, another side also can turn around to use, and after may wear to a certain degree, can continue built-up welding, prolong the service life of tup greatly, in addition hammer body by in, mild steel casting or forge and form the advantage that have good toughness, is not easy to fracture.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the front view of the utility model hammer head of hammer crusher.
Fig. 2 is the left view of the utility model hammer head of hammer crusher.
Fig. 3 is the vertical view of the utility model hammer head of hammer crusher.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of hammer head of hammer crusher comprises hammer body 2, in order to increase the firmness of welding, longitudinally have groove at hammer body 2 tops, described groove cuts off in the centre, form separately two sections, be welded with wear body 1 in the groove, described wear body 1 is formed by the wear resistance electrode built-up welding.Described wear body 1 thickness is between 15～30mm.Described hammer body 2 by in, mild steel casting or forge forms, and has the advantage of good toughness, non-frangibility.Hammer body 2 shanks have round open-work, be used for hammer mill hammer dish on bearing pin hinged.
Behind this tup one surface wear, the another side that can turn around to use, and after may wear to a certain degree, can continue built-up welding, thus prolong the service life of tup.
