Abstract
The invention discloses a kind of manufacturing methods of copper and iron base diamond cutter tooth, include the following steps：Carry out charging after the completion of mixing, mixing after carrying out the preparation of carcass material, preparation with framework material and bonded metal carry out it is hot-forming, hot-forming after carry out it is cooling, cooling after be machined, wherein the powder in the carcass material process for preparation includes Cu40%, Fe30%, Sn8%, Ni12% and WC10%, in mixing process be added weight be carcass material total weight 7% diamond, the diamond using 30% 35/40 mesh diamond, 40% 40/45 mesh diamond and 30% 45/50 mesh diamond.The present invention can replace the usage amount of the WC powder of part by addition Fe powder, reduce production cost, Sn powder can improve binder metal to the wettability of diamond, alloy melting point is effectively reduced, improves powder pressing performance, Ni powder can strengthen carcass mechanical property, and low-melting-point metal is inhibited to be lost, WC powder thermal conductivity is high, and thermal expansion coefficient and diamond are close, elasticity modulus with higher and hardness.
Description
Technical field
The present invention relates to diamond cutter tooth technical field, in particular to a kind of manufacturing method of copper and iron base diamond cutter tooth.
Background technique
In the market during manufacturing diamond cutter tooth, some consolidation cutting elements is needed to make the bonding of diamond
Agent, binder are divided into metal adhesive, resinoid bond, vitrified bonding etc., and wherein metal adhesive is production Buddha's warrior attendant lapicide
The main component of tool.Existing production technology is that diamond mixing is added with metal powders such as copper, cobalt, nickel, tin, through high temperature (800
DEG C or more) diamond cutter tooth is made after cooling down in hot pressed sintering, then diamond cutter tooth is welded on steel drilling pipe, thin-walled gold is made
Hard rock drill bit, the preparation of metal powder are to improve the density of framework material and generally use combination grain, gold in the prior art
Drill bit made of hard rock cutter tooth goes out to bore effect bad, and intensity is low, wear no resistance, service life is shorter.For this purpose, we mention
A kind of manufacturing method of copper and iron base diamond cutter tooth out.
Summary of the invention
The main purpose of the present invention is to provide a kind of manufacturing method of copper and iron base diamond cutter tooth, can effectively solve to carry on the back
The problems in scape technology.
To achieve the above object, the technical scheme adopted by the invention is as follows：
A kind of manufacturing method of copper and iron base diamond cutter tooth, includes the following steps：It is carried out with framework material and bonded metal
Cooling, cooling are carried out after the progress that charges after the completion of progress mixing, mixing after the preparation of carcass material, preparation is hot-forming, hot-forming
After be machined, wherein the powder in the carcass material process for preparation includes Cu40%, Fe30%, Sn8%, Ni 12%
And WC10%, 7% diamond that weight is carcass material total weight is added in mixing process, the diamond is using 30%
The diamond of 35/40 mesh, 40% 40/45 mesh diamond and 30% 45/50 mesh diamond.
Compared with prior art, the present invention has the advantages that：The WC powder of part can be replaced by addition Fe powder
Usage amount reduces production cost, and Sn powder can improve binder metal to the wettability of diamond, alloy melting point is effectively reduced, and improves
Powder pressing performance, Ni powder can strengthen carcass mechanical property, and low-melting-point metal is inhibited to be lost, and WC powder thermal conductivity is high, thermal expansion
Coefficient and diamond are close, elasticity modulus with higher and hardness, and diamond cutter tooth intensity produced by the present invention is high, wearability
Good, long service life.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Embodiment 1：
A kind of manufacturing method of copper and iron base diamond cutter tooth, includes the following steps：It is carried out with framework material and bonded metal
Cooling, cooling are carried out after the progress that charges after the completion of progress mixing, mixing after the preparation of carcass material, preparation is hot-forming, hot-forming
After be machined, wherein the powder in the carcass material process for preparation includes Cu40%, Fe30%, Sn8%, Ni 12%
And WC10%, 7% diamond that weight is carcass material total weight is added in mixing process, the diamond is using 30%
The diamond of 35/40 mesh, 40% 40/45 mesh diamond and 30% 45/50 mesh diamond.
Wherein, when carrying out hot-forming, the time of control, temperature, pressure are as shown in the table；
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.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.
Claims (1)
1. a kind of manufacturing method of copper and iron base diamond cutter tooth, it is characterised in that include the following steps：With framework material with it is Nian Jie
