Abstract

The utility model discloses a wear-resistant hammer of a crusher, aimed at overcoming the shortcomings of easy wear and short service life of the existing crusher hammers. The utility model is an integral structure comprising a hammer and a handle. The utility model is characterized in that wear-resistant strips or blocks are arranged on the upper, lower and side working faces of the hammer, wherein the wear-resistant strips or blocks at the upper and the lower working faces are perpendicular to the central connecting line of the hammer and the handle, with the exposed faces keeping level with the hammer surface; the wear-resistant strips or blocks at the sides of the hammer are parallel to or inclined to the central connecting line of the hammer and the handle, with the exposed faces protruding outside the hammer surface. As the wear-resistant strips or blocks are made of hard alloy materials and the contact area of the hammer with the materials is enlarged, the utility model has high intensity and good wear-resistance performance, thereby the service life of the hammer is prolonged. Practices show that the hammer can be continuously used for 180 to 210 hours, increased by 8 to 10 times compared with the existing hammers. Thus the utility model is applicable for the horizontal centrifugal crusher in the industries like metallurgy, mining and cement.

Description

The disintegrating machine wear-resistant hammer head

Technical field: the utility model relates to a kind of centrifugal crusher tup.

Background technology: at present, the grinder hammerhead that is used for the iron ore processing mostly is the light face tup of hammer handle tup one, mostly is M ₁₃With the cast steel hammer or the forged steel hammer of 45# steel, the defective of this tup mainly is easy to wear, and the life-span is short, normally uses generally also with regard to about 21 hours.Once introduced a kind of combined type tup in 1999 the 7th phases " mining machinery) " " improvement of standing crusher tup " literary composition, this tup adopts Hardmetal materials, its tup hammer handle is two bodies, Bolt Connection is passed through in the serration type interlock, and rely on bolt to regulate the length that tup leans out hammer handle, to prolong the service time of tup.The defective of this tup is, its binding site often just can not use phenomenon before to the greatest extent because of mechanical shock and the frequent wear-out life that appears at tup of regulating, so its life-span again so and shorten.And this hammehead structure complexity, processing inconvenience, cost height.

Summary of the invention:

The purpose of this utility model is at the problems referred to above, and a kind of disintegrating machine wear-resistant hammer head is provided, and it is simple in structure, the intensity height, and wearability is good, long service life.

Technical solution of the present utility model is: a kind of disintegrating machine wear-resistant hammer head, for tup hammer handle integrative-structure, it is characterized in that, and be provided with wear-resisting stick in three of upper and lower, the sides of tup one arbitrarily, two or three faces.

Wherein, be located at the line of centres of the wear-resisting stick of above and below, its exposed face and tup flush perpendicular to the tup hammer handle.The wear-resisting stick that is located at the side is parallel to the line of centres of tup hammer handle; Perhaps odd number distributes, the line of centres by the tup hammer handle in the middle of it, the line of centres that favours the tup hammer handle on both sides; Perhaps the wear-resisting stick in all sides all points to the pivot of disintegrating machine.And the exposed face that is located at the wear-resisting stick of side all protrudes the tup surface.

Compared with prior art, the utility model had both been saved material than the combination tup like this owing to be provided with the wear-resisting stick of carbide alloy on the working face of tup, and simplified structure is convenient to processing again, reduces cost; Increased contact-making surface with material than the light face tup of one, improved anti-wear performance, facts have proved that this tup can use 180-210 hour continuously, improved life-span 8-10 times than existing tup.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1 tup part.

Fig. 3 is the left view of Fig. 1.

Fig. 4 is existing combination hammehead structure schematic diagram.

The specific embodiment: as shown in the figure, the utility model is tup 2 hammer handles 1 integrative-structures, it is characterized in that being equipped with wear-resisting stick in three of upper and lower, the sides of tup 2.Wherein, be located at the line of centres of the wear-resisting stick 3 of above and below, its exposed face and tup flush perpendicular to the tup hammer handle.The wear-resisting stick that is located at the side in two kinds of situation, the wear-resisting stick 5 in the middle of it is by the line of centres of tup hammer handle, the wear-resisting stick 4 on both sides favours the line of centres of tup hammer handle, its exposed face all protrudes from the tup surface.The wear-resisting stick here can adopt the tungsten-cobalt-titanium alloy material, and its manufacture method can adopt the forged steel inlaying process, also can adopt cast steel to bury method underground.Wear rib number of blocks on each face then needs to be provided with according to tup size and needs, can be even number, also can be odd number.Can positive and negatively install during use, so as to improving its service life.

The utility model is applicable to the horizontal centrifugal crusher of industries such as metallurgy, mine, cement.
