Abstract
The invention discloses a kind of rock core cutter production methods, it is cast using addition carbon, manganese, cobalt, titanium and iron, is forged after casting and quenching technical, reprocessing are polished into available drill bit device, compared with prior art, the hardness for the drill bit that method through the present invention makes is high, and the performance with high abrasion, and the service life of drill bit cutting edge can be improved in construction, reduce the probability of more bit change, construction cost is reduced, working efficiency is improved, has the value of popularization and application.
Description
Technical field
The present invention relates to a kind of Work piece processing method more particularly to a kind of rock core cutter production methods.
Background technology
Rock sampling be examine or exploration a kind of technological means, in the prior art, the material of drill bit is more, as manganese steel,
Carbon steel, wolfram steel etc., although hardness is high, abrasion resistance is inadequate, causes service life low, and when construction constantly replaces green bit, at
This is higher, and reduces construction efficiency, and there are rooms for improvement.
Invention content
The purpose of the present invention is that solve the above-mentioned problems and provides a kind of rock core cutter production method.
The present invention is achieved through the following technical solutions above-mentioned purpose：
The present invention includes the following steps：
(1) be added in smelting furnace the carbon of weight ratio 0.1%, 0.05% manganese, 0.5% cobalt, 0.01% titanium, remaining be
Iron, stokehold carbon use ferromanganese adjusting component for 1：2：1, stokehold manganese uses ferro-cobalt adjusting component for 1：1：3, stokehold cobalt uses iron tune
It is made into and is divided into 1：1, it is iron liquid that temperature, which rises to 1650 DEG C to melt iron, the carbon after adjustment is added, temperature rises to 1680 DEG C, and adjustment is added
Manganese, cobalt and titanium deoxidation afterwards is come out of the stove；
(2) it comes out of the stove while being added in the blocky rare earth alloy mixing addition casting ladle of 3~5mm of granularity and pour；
(3) 0.05% fine aluminium is added in casting ladle, turns over stove tapping, calm temperature is down to 1550 DEG C of beginning pouring cast parts,
Volume is 5 times of required drill bit；
(4) casting temperature poured into a mould is forged to 900 DEG C or so, is forged cooling and is heated up and forge again again, until
The size of preliminary matches drill bit；
(5) rod piece forged lathe is removed into surface, then drill bit is processed into using drill bit processing unit (plant)；
(6) 700 DEG C are warming up to, is quenched；
(7) polished rod head surface polish drill bit cutting edge.
The beneficial effects of the present invention are：
The present invention is a kind of rock core cutter production method, compared with prior art, what the method through the present invention made
The hardness of drill bit is high, and the performance with high abrasion, and the service life of drill bit cutting edge can be improved in construction, reduces more bit change
Probability, reduce construction cost, improve working efficiency, have the value of popularization and application.
Specific implementation mode
The invention will be further described below：
The present invention includes the following steps：
(1) be added in smelting furnace the carbon of weight ratio 0.1%, 0.05% manganese, 0.5% cobalt, 0.01% titanium, remaining be
Iron, stokehold carbon use ferromanganese adjusting component for 1：2：1, stokehold manganese uses ferro-cobalt adjusting component for 1：1：3, stokehold cobalt uses iron tune
It is made into and is divided into 1：1, it is iron liquid that temperature, which rises to 1650 DEG C to melt iron, the carbon after adjustment is added, temperature rises to 1680 DEG C, and adjustment is added
Manganese, cobalt and titanium deoxidation afterwards is come out of the stove；
(2) it comes out of the stove while being added in the blocky rare earth alloy mixing addition casting ladle of 3~5mm of granularity and pour；
(3) 0.05% fine aluminium is added in casting ladle, turns over stove tapping, calm temperature is down to 1550 DEG C of beginning pouring cast parts,
Volume is 5 times of required drill bit；
(4) casting temperature poured into a mould is forged to 900 DEG C or so, is forged cooling and is heated up and forge again again, until
The size of preliminary matches drill bit；
(5) rod piece forged lathe is removed into surface, then drill bit is processed into using drill bit processing unit (plant)；
(6) 700 DEG C are warming up to, is quenched；
(7) polished rod head surface polish drill bit cutting edge.
The basic principles and main features and advantages of the present invention of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
