Abstract

The utility model discloses a honeycomb bimetallic composite hammer. A hammer matrix is made from alloy steel materials. A group of honeycomb wear-resisting bars are arranged at the inner part of the hammer end. The external surfaces of the wear-resisting bars are closely combined with matrix metal of the hammer body. The honeycomb bimetallic composite hammer has the advantages that: a group of honeycomb wear-resisting bars are arranged at the inner part of the hammer end so that the impact resistance of the hammer matrix is kept and the wear resistance of the hammer is substantially improved. During use, the hammer does not drop off and is not broken and the service life of the hammer is as high as 2.5 times the service life of a common high-manganese steel hammer.

Description

The honeycomb type bimetallic composite hammer

Technical field

The utility model belongs to rock processing equipment accessory technical field, is specifically related to a kind of honeycomb type bimetallic composite hammer.

Background technology

China is vast in territory, rich in minerals, and is along with the fast development of China's mining industry, more and more higher to the efficient and the requirement in life-span of mine mechanism.In most cases, mining industrial and mineral condition is very abominable, mineral metal products particularly, and corrosivity such as ore hardness height, soda acid are strong, to the serious wear of mining equiment.Breaking ores is the first step of ore dressing, and nearly all ore all must be through broken.

Tup is the critical piece of breaking ores in the impact breaker, and these parts are the hammer handle bending stress and the impulsive force of constantly bearing alternation in use, and stronger impulsive force and frictional force are then mainly born in the tup position.At present, employed tup mostly is high-manganese steel matter greatly on impact breaker, because potassium steel has wearability and stronger toughness preferably, however, the potassium steel tup generally can only use about 7 ~ 10 days (about 80 hours) continuously, and its main failure mode is tup self fragmentation, come off even rupture.

Summary of the invention

The purpose of this utility model provides a kind of honeycomb type bimetallic composite hammer, has solved the short problem of the tup that exists in prior art fragmentation easy to wear, easy, service life.

The technical scheme that the utility model adopted is that the honeycomb type bimetallic composite hammer is made up of hammer handle that is connected and termination, is provided with many wear-resisting bars in the termination; Combine closely in the outer surface and the termination of wear-resisting bar.

Wherein, wear-resisting bar is with the cellular inside, termination that is distributed in, and is parallel to each other between the many wear-resisting bars and is vertical setting.

Wherein, wear-resisting bar is made up of wear-resisting club shaft, wear-resisting bar upper end and wear-resisting bar lower end; Wear-resisting club shaft is the cylinder that diameter reduces from top to down gradually; Wear-resisting bar upper end is hemispherical, and wear-resisting bar lower end is concordant with the bottom surface of tup termination.

The beneficial effects of the utility model are that the shaft-like high-abrasive material in inside, hammer body termination with certain specification is embedded in the parent metal to be similar to cellular layout, on the basis that increases substantially the tup anti-wear performance, has kept the ability of tup opposing impact.Tup strong shock resistance, not broken in use, anti-wear performance is good, reaches 2.5 times of common potassium steel tup service life.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As depicted in figs. 1 and 2, the utility model provides a kind of honeycomb type bimetallic composite hammer, is made up of hammer handle 1 that is connected and termination 2, and hammer handle 1 and termination 2 all are the steel alloy material.Be provided with the many wear-resisting bars 3 that are cellular distribution in the termination 2, be parallel to each other between the many wear-resisting bars 3 and be vertical setting, wear-resisting bar 3 is arranged on tup position the most easy to wear; The outer surface of wear-resisting bar 3 and termination 2 matrixes are combined closely, and are equivalent to the wear-resisting particle that disperse distributes in 2 matrixes of tup termination, make tup increase substantially the wearability of tup on the basis of not destroying the matrix resistance to impact substantially.As shown in Figure 3, wear-resisting bar 3 is made up of wear-resisting club shaft 4, wear-resisting bar upper end 5 and wear-resisting bar lower end 6; The cylinder that wear-resisting club shaft 4 reduces from top to down gradually for diameter; Wear-resisting bar upper end 5 is hemispherical, and wear-resisting bar lower end 6 is concordant with the bottom surface of tup termination 2.3 pairs of tup terminations of wear-resisting bar, 2 the isolating property of matrix that disperse distributes are less, thereby make matrix keep its original intensity (impact flexibility) preferably; The gross mass of all wear-resisting bars 3 is approximately 10% of tup quality.

From stress form, tup is owing to the bending stress and the impulsive force of constantly bearing alternation, thereby toughness that need be stronger, so tup adopts the stronger steel alloy of toughness; And termination 2 power that should withstand shocks is born stronger frictional force again, thus in the termination 2 positions the most easy to wear, one group of cellular wear-resisting bar 3 is set, wear-resisting bar 3 adopts the stronger high-chromium abrasion-proof cast iron of wearabilities.High chromium series wear resistant cast iron tissue is by the stronger matrix of toughness and the isolated island shape M of hard ₇C ₃The type carbide is formed, and has stronger resistance to impact and good wearability, detects through relevant test, and its wearability is approximately more than 3 times of potassium steel.Therefore, adopt steel alloy to do hammer handle 1 and termination 2, adopt the high chromium series wear resistant cast iron to make wear-resisting bar 3, with wear-resisting bar 3 with the cellular position the most easy to wear, tup termination 2 that is arranged in, and termination 2 and the wear-resisting bar of high-chromium abrasion-proof cast iron 3 surfaces are combined in metallurgical mode, thereby increase substantially the service life of grinder hammerhead, reduce tup and change frequency, improve disintegrating machine production efficiency.

The utility model is applicable to following impact breaker serviceability requirements such as Φ 1000 * 1200 types, does not in use come off, not broken, reaches 2.5 times of common potassium steel tup service life.
