Abstract
The utility model discloses a compound hammer for reaction crusher, comprising a reverse-trapezoid hammer head as communicated to an alloy steel handle, an abrasion-resistant block made of chrome abrasion-resistant cast iron being arranged at inclined planes of each end of the head, abrasion-resistance inclined planes being provided on the block through connecting closely with the inclined planes of the head, a dovetail-shaped groove being sunk from top to bottom of the inclined plane of the abrasion-resistant groove, a dovetail-shaped protruding block being provided on the inclined planes of the head and corresponding to position of the groove, the protruding block being embedded in the groove.
Description
Technical field
The utility model belongs to rock processing equipment accessory technical field, is specifically related to a kind of impact breaker 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.
Bar 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 3～5 days (about 40 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 impact breaker 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, the impact breaker composite hammer comprises the termination that is connected and the hammer handle of steel alloy material, and the termination respectively is provided with the wear-resistant block of a chromium family wear-resisting cast iron material for trapezoidal on the inclined-plane, termination of both sides, termination; Wear-resistant block is provided with the wear-resistant block inclined-plane of combining closely with the inclined-plane, termination; The wear-resistant trough inclined-plane is provided with a dovetail groove that connects from top to bottom, and the inclined-plane, termination is provided with and the corresponding swallow-tail form projection of dovetail groove; Described swallow-tail form projection is embedded in the dovetail groove.
Characteristics of the present utility model also are,
The groove floor of groove wherein is parallel with the wear-resistant block inclined-plane.
It is big that the width of groove wherein becomes from top to bottom gradually.
The beneficial effects of the utility model are, on the hammer handle termination wear-resistant block are set, and have improved the opposing impact capacity of tup.In use tup do not come off, not broken, reach 2.5 times of common potassium steel tup service life.
Description of drawings
Fig. 1 is the structural representation of the utility model tup;
Fig. 2 is the structural representation of the utility model wear-resistant block;
Fig. 3 is that the A of Fig. 2 is to view;
Fig. 4 is that the B of Fig. 2 is to view.
Among the figure, 1. hammer handle, 2. termination, 3. wear-resistant block, 4. groove, 5. wear-resistant block inclined-plane, 6. inclined-plane, termination, 7. groove floor.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model provides a kind of impact breaker composite hammer, as shown in Figure 1, this tup comprises hammer handle 1 and the termination 2 that is connected, and termination 2 is for trapezoidal, respectively be provided with a wear-resistant block 3 on the inclined-plane, termination 6 of 2 both sides, termination, make tup have stronger resistance to impact and wearability; Also be provided with the wear-resistant block inclined-plane 5 of combining closely on the wear-resistant block 3 with inclined-plane, termination 6.As shown in Figures 2 and 3, wear-resistant trough inclined-plane 5 is provided with a dovetail groove 4 that connects from top to bottom, and inclined-plane, termination 6 is provided with and dovetail groove 4 corresponding swallow-tail form projections.The groove floor 7 of groove 4 is parallel with wear-resistant block inclined-plane 5.As shown in Figure 4, the width of groove 4 becomes big from top to bottom gradually.The force-bearing situation of the setting of wear-resistant block groove 4 from combining between structure has been improved wear-resistant block inclined-plane 5 and inclined-plane, termination 6 improved the ability that the tup opposing is impacted.
From stress form, hammer handle 1 is owing to the bending stress of constantly bearing alternation, thereby toughness that need be stronger, so hammer handle 1 adopts the stronger steel alloy of toughness; And wear-resistant block 3 mainly bears frictional force and impulsive force, so wear-resistant block 3 adopts impact resistance and the stronger chromium family wear-resisting cast iron of wearability.The chromium family wear-resisting cast iron is inlayed the M7C3 type carbide of hard in the stronger matrix of toughness, have 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, adopt the chromium family wear-resisting cast iron to do the service life that wear-resistant block 3 can increase substantially bar, thereby improve service life of equipment, reduce bar and change frequency, improve disintegrating machine production efficiency.
The disclosed bar of the utility model can satisfy 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.
