Description
Technical Field
The invention relates to the technical field of mechanical crushing, in particular to a novel material mechanical crushing hammer sheet and a preparation process thereof.
Background
The hammer is a workpiece part of the crusher directly impacting materials and is a quick-wear part which is worn most quickly and replaced most frequently. At present, in the aspect of preparing mechanical breaking hammer sheets at home and abroad, low-carbon steel and medium-carbon steel plates are generally subjected to punch forming, special cast iron and the like. Weo increases the wear resistance to carry out heat treatment and surface hardening, and the high-end hammer piece improves the service life of the hammer piece by surfacing tungsten carbide or hard alloy on the impact surface of the steel hammer piece. Taking a pulverizer as an example, the high-end hammer is a semi-automatic surfacing tungsten carbide hammer introduced from the United states, the service life is about 10 days on average, the machine is frequently stopped and replaced, the output of waste steel is large, the energy consumption and the time consumption are realized, and the national resources are wasted.
Disclosure of Invention
Aiming at the situation, in order to overcome the defects of the prior art, the invention provides a novel material mechanical breaking hammer sheet and a preparation method thereof, and the problems of short service life and poor wear resistance of the existing breaking hammer sheet are effectively solved.
In order to achieve the purpose, the technical scheme of the invention is as follows: a new material mechanical breaking hammer comprises a hammer body, wherein the hammer body is made of a new material;
the new material comprises the following substances in mass ratio: 46% of tungsten carbide, 12% of diamond, 6% of nickel, 8% of cubic boron nitride, 7% of boron carbide, 5% of cobalt, 2% of silicon, 3% of titanium, 8% of a L-wave and 3% of molybdenum.
A preparation process of a new material mechanical breaking hammer slice comprises the following steps:
s1, weighing corresponding raw powder according to a certain proportion;
s2, placing the raw powder into a mold, and carrying out static pressure molding on the raw powder through the mold;
s3, sintering the hammer blank in a high-temperature vacuum furnace at the sintering temperature of 1200-1390 ℃;
s4, after the sintering treatment is finished, taking out the hammer piece when the furnace temperature is reduced to 50-80 ℃;
and S5, manufacturing the hammer sheet into a non-flat friction surface crushing hammer sheet.
The invention reduces the shutdown frequency, reduces the maintenance cost, improves the working efficiency, improves the stability of the product quality, and reduces the output of waste steel, and the product has super-hard and wear-resistant performance and long service life, which is more than 10 times of that of the prior high-end hammer piece.
Detailed Description
In the prior art, the crushing hammer piece has the defects of poor friction and impact resistance, short service life in use, frequent replacement, frequent shutdown, influence on efficiency, poor product stability, large recovery smelting scale, resource waste and the like.
The invention aims to solve the problems that the existing breaking hammer is easy to wear and not wear-resistant, the existing breaking hammer is frequently replaced due to shutdown, the existing breaking hammer is poor in product stability, and the problems that the waste steel output of the hammer is large, energy is not saved and emission is not reduced are solved.
The invention selects from the raw materials, thereby solving the problems, and the raw materials of the invention comprise 46% of tungsten carbide, 12% of diamond, 6% of nickel, 8% of cubic boron nitride, 7% of boron carbide, 5% of cobalt, 2% of silicon, 3% of titanium, 8% of a secondary wave and 3% of molybdenum.
The preparation process includes mixing the said powder material in a mixer, static pressure molding in mold, sintering in high temperature vacuum furnace at 1200-1390 deg.c. And after the sintering treatment is finished, taking out the hammer piece when the furnace temperature is reduced to 80-50 ℃. Because the surface of the material crystal is purified at high temperature under the protection of high vacuum, a reasonable and stable internal covalent bond organizational structure is formed.
Regarding the appearance design of the hammer: aiming at the working principle of the breaking hammer sheet, the breaking hammer sheet with non-flat friction surfaces such as strips, diamonds, arcs, waves and the like is designed, multi-edge cutting is realized, and the cutting, impacting and friction functions of the hammer sheet are greatly improved. Increasing the number of cut friction faces and thus increasing their performance.
The traditional hammer sheet is a heterogeneous monomer, the product of the invention is a homogeneous monomer, the traditional hammer sheet is locally wear-resistant, and the invention is wholly wear-resistant.
The traditional hammer sheet is a stamping and surfacing process, and the hammer sheet adopts a powder metallurgy process.
The traditional hammer sheet is an edge cutting mechanism, and the hammer sheet can cut by a plurality of edges.
The invention reduces the shutdown frequency, reduces the maintenance cost, improves the working efficiency, improves the stability of the product quality, reduces the output of waste steel, and the product is superhard, wear-resistant and long in service life, which is more than 10 times of the prior high-end hammer.
The service life of the hammer sheet on the market is 7-10 days, and the hammer sheet is used for nearly 100 days in the application and can still be normally used.
The examples are given solely for the purpose of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
