Abstract
The utility model relates to a hammerhead, in particular to a bimetallic composite wear-resistant hammerhead for crushers, which belongs to the technical field of crushing machines. The hammerhead comprises an upper hammerhead part (1) and a lower hammerhead part (2), the bottom of the upper hammerhead part (1) is provided with wedged protrusions (3), the top of the lower hammerhead part (2) is provided with wedged grooves corresponding to the wedged protrusions (3), the upper hammerhead part (1) adopts high manganese steel, medium manganese steel, low alloy steel, carbon steel or cast iron, and the lower hammerhead part (2) adopts high chromium cast iron, low chromium cast iron or hard alloy. The hammerhead has the advantages of high wear resistance and long service life.
Description
(1) technical field
The utility model relates to a kind of tup, specifically relates to a kind of bimetal composite wear resistant tup that is used for disintegrating machine, belongs to the crushing mechanism technical field.
(2) background technology
The broken tup of the hammer of sector applications such as present domestic metallurgy, mine, cement, building materials, electric power, highway mainly contains two kinds of potassium steel tup and composite hammer heads.Owing to reasons such as preliminary work hardening rate are not enough, the potassium steel tup can not effectively have been given play to its internal potential, cause in use not wear-resisting, too early spalling failure, service life is short.In recent years, composite hammer head has also obtained some application, but in recombination process, two parts of tup are difficult to metallurgical binding takes place, and generally all remain the mechanical bond mode, and it is little to cause most of composite hammer head life-span to be improved.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of service life long bimetal composite wear resistant tup.
The purpose of this utility model is achieved in that a kind of bimetal composite wear resistant tup, is characterized in: it comprises tup top and tup bottom, and the tup upper bottom is provided with the wedge shape projection, and top, tup bottom is provided with corresponding with it wedge-shaped impression.
Potassium steel, medium managese steel, low-alloy steel, carbon steel or cast iron are adopted in described tup top.
Rich chromium cast iron, low-chromium cast-iron or carbide alloy are adopted in described tup bottom.
Compared with prior art, the beneficial effects of the utility model are:
A kind of bimetal composite wear resistant tup of the utility model, impact flexibility is adopted on its tup top, and potassium steel, medium managese steel, low-alloy steel, carbon steel or cast iron process preferably, wearability is adopted in the tup bottom, and rich chromium cast iron, low-chromium cast-iron or carbide alloy process preferably, be one by wedge shape projection and groove mechanical bond then, the tup anti-wear performance is better, and service life is longer.
(4) description of drawings
Fig. 1 is the structural representation of a kind of bimetal composite wear resistant tup of the utility model.
Wherein:
Tup top 1, tup bottom 2, wedge shape projection 3.
(5) specific embodiment
Referring to Fig. 1, the utility model relates to a kind of bimetal composite wear resistant tup, it comprises tup top 1 and tup bottom 2,1 bottom, tup top is provided with wedge shape projection 3,2 tops, tup bottom are provided with corresponding with it wedge-shaped impression, impact flexibility potassium steel, medium managese steel, low-alloy steel, carbon steel or cast iron are preferably adopted in tup top 1, and anti-wear performance rich chromium cast iron, low-chromium cast-iron or carbide alloy are preferably adopted in tup bottom 2.
Claims (3)
1. bimetal composite wear resistant tup, it is characterized in that: it comprises tup top (1) and tup bottom (2), and tup top (1) bottom is provided with wedge shape projection (3), and top, tup bottom (2) is provided with corresponding with it wedge-shaped impression.
2. a kind of bimetal composite wear resistant tup according to claim 1 is characterized in that: potassium steel, medium managese steel, low-alloy steel, carbon steel or cast iron are adopted in described tup top (1).
3. a kind of bimetal composite wear resistant tup according to claim 1 is characterized in that: rich chromium cast iron, low-chromium cast-iron or carbide alloy are adopted in described tup bottom (2).
