This invention relates to a hammer that has improved wear resistance by being filled with a metal material of high hardness such as steel.
解体した車両の鉄板等を特殊形状のハンマーで
打ち砕き再生を計る破砕装置が知られている。 A crushing device is known that uses a specially shaped hammer to crush the steel plates and other materials from dismantled vehicles in order to regenerate them.

る。 For example, as shown in FIG. 1, these devices include a hammer 3 rotatably attached to the tips of multiple pairs of brackets 2 fixed to a rotating shaft 1, and driven by a drive device (not shown) such as a motor. By rotating the rotary shaft body 1, iron plates and the like of the demolished vehicle sent to the crushing device are successively crushed by the hammer 3.

という欠点があつた。 The hammer 3 used in this device hits hard materials like this, and is also subjected to severe impacts such as adjacent hammers colliding with each other when the rotating shaft is stopped, so it is hardened to obtain hardness. has been done. However, conventional hammers of this type usually require a weight of at least 30 kg per piece, and because they are extremely thick and have a large volume, only the 3' area near the outer surface is hardened, and attempts are made to forcibly increase the hardening depth. Then, a problem arises in that the hardness near the surface increases too much, making it brittle. In this way, conventional hammers of this type cannot harden the inside of the wall, so they suffer from significant wear due to impact, and the
After being used for about two weeks, it shrinks to the shape shown by broken line 3'' in FIG. 2, resulting in an extremely short lifespan.

あつた。 In order to solve this problem, the applicant first
By drilling multiple holes in the wall thickness of the striking part of the hammer body and hardening the entire hammer, we have developed a hammer that has been quenched to a certain depth near the outer circumferential surface of the hammer and near the inner circumferential surface of the through holes. Then, he filed an application for utility model registration as Utility Model No. 164201/1983.
However, with this structure, the inside of the hole in the hammer body is hollow, so when the hammer body wears down to the vicinity of the cavity due to use, it will rapidly shrink and deform due to impact, and there is a problem that sufficient durability cannot be obtained. It was hot.
本考案はこの点の改善に向けられたもので、肉

とするものである。 The present invention is aimed at improving this point, and aims to further extend the life of the hammer by increasing the hardness inside the wall thickness and preventing early deformation.
以下、本考案の一実施例を図面に基づいて説明
する。 Hereinafter, one embodiment of the present invention will be described based on the drawings.

填材５を嵌着したものである。 Fig. 3 shows a longitudinal cross section of the hammer body for a crushing device according to the present invention.The hammer body 3 has a plurality of through holes 4, 4, . By quenching, hardened layers 3', 4' of a certain depth are formed near the outer circumferential surface of the hammer body 3 and near the inner circumferential surface of the hole, and steel or other wear-resistant metal filling material is formed in each through hole 4. 5 is fitted.

ないようにすることも可能である。 The metal filler 5 is preferably made of a material with hardness approximately equal to or higher than that of the quenched hardened layer 4', and the through holes 4 are formed so that it does not easily come off due to impact.
Insert firmly by welding, press-fitting, etc. In the figure, the cross section of the through hole 4 and the metal material 5 filled therein is formed into a circular shape, but the hammer body 3 is not limited to this, and by forming these cross sections into an inverted trapezoid or star shape, for example. Even if the portion of the through hole 4 is worn out, the metal material 5 may be engaged with the through hole 4 and not easily separated.
尚、６はハンマ本体３をブラケツト２（第１図

る。 The reference numeral 6 designates a shaft mounting hole for swingably connecting the hammer body 3 to the bracket 2 (see FIG. 1).

長する効果が得られる。 As described above, the hammer of the present invention has a hardened layer formed not only on the outer circumferential surface but also on the inside of the through hole by annealing the inner circumferential surface of the through hole, which improves wear resistance and improves wear resistance. Since the hammer is not hollow as in the conventional case, but is filled with a hard material, the wear rate of the hammer temporarily slows down near the through hole, resulting in the effect of significantly extending the service life of the hammer.
