Abstract
The present invention is brazing method for tool of superhard material. The brazing method is to heat the rotating superhard material, brazing alloy and base inside a protecting hood filled with inert gas inductively by means of an AC power source so as to smelt the brazing alloy. The present invention realizes local heating and rotation of the heated base, and has homogeneous temperature, less deformation of base, low power consumption and obviously raised production efficiency.
Description
Technical field
The present invention relates to the method for welding and the equipment thereof of tool made of superhard material.
Background technology
Tool made of superhard material is superhard materials such as diamond, cubic boron nitride attached on the matrix and form, and generally comprises emery wheel, cutting blade etc., is mainly used to hard brittle materia carried out processing such as grinding, cutting.With diamond, cubic boron nitride attached to the general method for welding that adopts on the matrix.During soldering, be superhard material, scolder, matrix to be placed in the vacuum drying oven heat, scolder is melted, then cooling.Because of being to realize soldering in vacuum drying oven, its shortcoming and defect is conspicuous: 1, vacuum drying oven is that matrix integral body is heated, and not only the matrix distortion is big; And power consumption is high, and cost is big, is not suitable for single-piece work especially; 2, after matrix integral body was heated, cool time was longer, so production efficiency low (every stove needs 12-16 hour); 3, since in the stove of vacuum drying oven temperature distributing disproportionation even, and the matrix in vacuum drying oven can not be seen, causes the qualification rate of finished product low.
Summary of the invention
The purpose of this invention is to provide the braze welding of tool made of superhard material method that a kind of matrix distortion is minimum, power consumption is low, production efficiency is high.
This method is to be opposite in the protective cover that is full of inert gas and superhard material that rotating, scolder, matrix carry out eddy-current heating with AC power, melts scolder, then cooling.
In this method, scolder reacts scolder and surface of ultra-hard material, matrix surface after melting, and realizes superhard material, scolder, matrix three's strong bonded.Beneficial effect of the present invention: owing to adopt the AC power eddy-current heating, because eddy-current heating strong the inside on the object surfaces a little less than, so can realize local heat, i.e. the place of this heating adds, what should not add does not heat, and the place distortion of required precision is reduced greatly; Add that matrix is rotated when heating, solved the temperature uneven phenomenon, make brazing quality be guaranteed, also make distortion reduce; Because just heat to the surface of matrix rather than to matrix integral body, thus not only cut down the consumption of energy, and also the material heat radiation is very fast during cooling, has obviously improved production efficiency.
For method recited above, eddy-current heating is high frequency or Frequency Induction Heating.When the face of cylinder of rule is heated, adopt high-frequency induction heating power (generally greater than 50KHz), when solder side is the curved surface of complexity, adopt intermediate frequency induction heating power supply (being generally 500Hz-10KHz).
For method recited above, described protective cover adopts quartz cover.Employing is the protective cover of material with the quartz, and operating personnel can see through quartz cover and see welding process, to monitor the welding situation at any time, guarantee welding quality.
For method recited above, the velocity of rotation of matrix is 30-50 rev/min; Inert gas adopts argon gas.
The special equipment that has used in the described method above the present invention provides simultaneously, the housing that it comprises protective cover, pass protective cover stretch into turning cylinder and air inlet pipe in the protective cover, be arranged on the induction coil around the housing; Be connected with the pallet that is used to place matrix on the turning cylinder in protective cover, turning cylinder is connected with rotating mechanism; Air inlet pipe is connected with inert gas source.
During use, the air inlet pipe air inlet by being connected with inert gas source earlier makes to be full of inert gas in the protective cover; Make then rotating mechanism drive turning cylinder and rotate that matrix begins rotation; Again to induction coil energising beginning heating.After scolder melts, the induction coil outage, matrix cools off under inert gas shielding.
Description of drawings
Fig. 1 is the structural representation of described special equipment of the present invention.
The specific embodiment
Braze welding of tool made of superhard material equipment shown in Fig. 1, protective cover comprise the main body cover 1 on top and the cover holder 2 that is arranged on the main body cover below and is tightly connected with main body cover.Main body cover 1 adopts quartz cover.Cover holder 2 external diameters according to the quartz cover mouth are got on the bus out and the corresponding sealed groove 3 of quartz cover mouth at its end face, implement sealing with high-temp glue, and the heat resisting temperature of glue is 600 ℃.Pass cover holder 2 and stretch into the interior turning cylinder 5 tops connection pallet 7 of protective cover.Place matrix 9 on the pallet 7.
The top of main body cover has the venthole 4 of Φ 2-3mm.The internal diameter of main body cover is greater than the external diameter 6-12mm of matrix, and height will be higher than matrix height overall 10-30mm, and wall thickness is at 3-5mm.
Turning cylinder 5 bottoms are connected with the rotatable parts (not shown).The air inlet pipe 6 that is connected with the argon gas source (not shown) is passed cover holder 2 and is stretched in the protective cover.The induction coil 8 that joins with power supply is arranged on around the main body cover 1.
The following describes the using method of the said equipment.
1. select suitable scolder, and superhard material is invested on the matrix.
2. according to matrix size and concrete shape, select the quartz cover that is fit to.
3. matrix is covered in the quartz cover, the induction coil that is fit to is enclosed within on the quartz cover.
4. in quartz cover, charge into argon gas, the air in the cover is fully discharged intestine evacuation velocity: 20 liters/minute.
5. rotating mechanism drives the turning cylinder rotation, and matrix is with 40 rev/mins of rotations; Open the power supply of induction coil simultaneously, the temperature of heating is controlled at 850-950 ℃, by perusal, waits whole scolders evenly after the fusing, stops heating immediately.
6. treat that scolder all melts, stop heating.
7. cooled off 40 minutes in atmosphere, close argon gas, take out product, welding sequence finishes.
The beneficial effect of present embodiment.
1. raising yield rate, this technology can reach more than 95; Vacuum drying oven soldering yield rate originally is generally 85%.
2. the finished product distortion is little, improves the product precision.
3. production efficiency obviously improves, and is particularly suitable for single-piece work.
4. cut down the consumption of energy, vacuum drying oven once consumes nearly 400 kilowatts of electric power, but this technology is no more than 10 kilowatts.
