Abstract
The utility model relates to a hammer piece of a material disintegrator, in particular to a high anti-abrasion hammer piece of the disintegrator which is formed by peripherally build-up welding tungsten carbide alloy. In the utility model, the four corners and the surroundings of a hammer piece base (2) are provided with a high wear-resistant coating (1, 3) which is made from different materials with the hammer piece base (2). The utility model has the advantages that the service life of the hammer piece is prolonged and the service life of the high anti-abrasion hammer piece of the disintegrator is 10 times longer than that of the general hammer piece of quality carbon steel proved by the test; because the service life of the high anti-abrasion hammer piece of the disintegrator is long, the high anti-abrasion hammer piece of the disintegrator can save a great amount of steel, the time of the machine halt for exchanging the hammer piece is reduced, the regular production can be done normally in the product line, and the production efficiency is improved.
Description
Technical field
The utility model relates to the materials crusher hammer leaf, refers in particular to a kind of high abrasion hammer mills with the built-up welding of diamondite periphery.
Background technology
According to the regulation of machinery industry standard " hammer slice type Hammer-Block in Feed Grinder " JB/T9822.2-1999 of the People's Republic of China (PRC), hammer leaf is that rectangular flat plate is a rectangle, and thickness is 3.5~5mm, and material is carbon constructional quality steel 65Mn.In actual moving process, the effective working portion of hammer leaf pulverizes material by rotating the impulsive force that produces at a high speed near hammer leaf periphery end points, and other part contact materials seldom, thereby wearing and tearing are the fastest near the end points, and effectively working portion only accounts for 10~20% of whole hammer leaf.Therefore, if the hammer leaf material monolithic adopts carbon constructional quality steel, its non-productive work partly is 80~90% of a hammer leaf, a kind of waste, because Fine Steel Casting iron and 65Mn are higher more than 2000 yuan than common straightcarbon steel valency per ton, and Fine Steel Casting iron in pulverizer under the strong percussion wearability strong not as diamondite.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of long service life is provided, and saves steel, high abrasion hammer mills safe in utilization.
The purpose of this utility model is such realization: at four jiaos and the peripheral high abrasion shoe cap rock that is different from the hammer leaf matrix material that is provided with of hammer leaf matrix.
The utility model has following advantage:
1, improved the service life of hammer leaf.Experimental results show that: be 10 times of general Fine Steel Casting iron hammer leaf the service life of this kind high abrasion hammer mills.
2, save the steel material.Because the long service life of high abrasion hammer leaf is so can save great deal of steel.
3, because hammer leaf has improved service life, make it to shut down the time decreased of changing hammer leaf, cause production line energy ordinary production, enhance productivity.

The specific embodiment
By Fig. 1,2,3 as can be known, the utility model is at four jiaos and the peripheral high abrasion shoe cap rock (1,3) that is different from hammer leaf matrix (2) material that is provided with of hammer leaf matrix (2).
Shoe cap rock described in the utility model (1,3) forms along matrix (2) periphery and four jiaos of built-up welding with the cast tungsten carbide welding rod.Described hammer leaf matrix (2) is provided with installs pin-and-hole (4).
The utility model is to use the hammer leaf of using carbon constructional quality steel 65Mn production originally instead carbon structural steel A3 to produce the hammer leaf matrix, uses the cast tungsten carbide welding rod along the built-up welding of matrix periphery then.Hammer leaf the easiest fray of when work---four jiaos, should add two layers of welderings, after built-up welding is finished, should be with the hammer leaf bulk heat treatmet, pin-and-hole place hardness should rationally be mated with bearing pin hardness, facts have proved, uses this hammer leaf can significantly improve hammer leaf normal service life.
The utility model hammer leaf uses common straightcarbon steel Q235 as the hammer leaf matrix.
Claims (3)
1, a kind of high abrasion hammer mills is characterized in that the high abrasion that four jiaos of hammer leaf matrix (2) and periphery setting are different from hammer leaf matrix (2) material carries out cap rock (1,3).
2, high abrasion hammer mills according to claim 1 is characterized in that described shoe cap rock (1,3) forms along matrix (2) periphery and four jiaos of built-up welding with the cast tungsten carbide welding rod.
3, high abrasion hammer mills according to claim 1 is characterized in that described hammer leaf matrix (2) is provided with installation pin-and-hole (4).
