Description
Technical field
The present invention relates to the coated chip production technical field, relate in particular to loading appliance and application thereof that chemical Vapor deposition process is produced coated chip.
Background technology
Coating technology is widely used in the carbide numerical control cutter, is the again technological revolution of metal cutting field after Wimet is used.Wherein chemical Vapor deposition process is widely used cutter coat technology, wherein finish in the hot cell in the process of applying coating on the cutter, its process principle is that cutter is placed the hot cell, one or more gas phase compounds, the elementary gas that contain the film element that are full of in the hot cell carry out chemical reaction, deposit the solid film that generates certain thickness, has desired characteristic at tool surface.In this production technique, the concentration of hot cell reaction gases, proportioning and total flux are obvious to the coating performance influence that deposition generates, discover, enter under the constant prerequisite of hot cell flow velocity at forerunner's reactant gases, the position relation of cutter and its loading appliance, volume ratio, surface area ratio are most important to the control of cutter coating quality, have a strong impact on the coating effect of coating.On the other hand, the loading appliance that adopts also restricts single stove charge amount, and then influences the production cost of coated chip.Be example with the coating stove for the production of CVD coating numerical control blade in the prior art, the structure of such device is described: the charging pit furnace is produced blade with holes under adopting, blade with holes is adorned boat in pad dress mode, and the boat stacking after will feeding then gets up and carry out coating in stove.The charging boat of being adopted mostly is the monoblock type disc structure of graphite material, processing cutting milling in the upper surface, the hole is processed with the pad awl cone of several loading blades, bore the ventilating pit that several are used for sending into reactant gases, the pad awl is integral structure with boat, as Fig. 1, shown in Figure 2, in the insert coating production process, after the blade charging is finished, the coating atmosphere gas is transported to each layer loading tray from central gas atmosphere transfer lime, then after the atmosphere jet hole enters reaction zone, a part is radially by flowing out after the blade face, a part is transported to the last layer charging tray by the charging tray ventilating pit, thereby realizes the even coating of blade.Therefore distributing position, cone height and the volume size of loading tray upper vent hole and cone should be distributed the processing requirement design by gas, guarantee that processing requirement is satisfied in the flow direction and the distribution of furnace gas.
Above-mentioned whole graphite charging boat is except shortcomings such as difficulty of processing is big, body intensity is difficult to meet the demands, involves great expense, can not recycles, and also there is following problem in its structure aspects in actual production process:
1, this charging boat disk body is blocked up, and the pad awl is fixed as one with the boat disk body, and the cone volume is big, surface-area is big, floorage is big, materials are many, weight is big, therefore should take up space in stove greatly by the integral body boat.Because facies basialis pyramidis is long-pending big, all reduce in cone quantity in the unit surface and percentage of open area and the aperture of ventilating pit, both reduced the loading capacity of individual layer boat, influence conveying and the homogeneity of upper lower burrs atmosphere in the stove again, cause the invalid loss of atmosphere in the coating generative process, thereby influence gas reactant in the utilization ratio of insert coating generative process.
2, in the charging process, blade is shelved with the form that centre hole is placed on the cone, and the two back overall height that highly superposes is higher, has both influenced the circulation of atmosphere, and the number of plies of the same following boat of adorning of furnace volume prerequisite is reduced, and reduces production capacity.
3, because pad awl is to form by Milling Process with monoblock graphite with charging tray, so the cone position is unreasonable with the collocation of ventilating pit position, and after blade loaded thereon, position of tool tip is very difficult to be fallen above the ventilating pit just.After simultaneously blade was loaded into the pad awl and goes up, because the cone volume is big, the blade lower surface had been blocked a part by cone, in coating procedure, has the atmosphere blind area at the blade lower surface, makes coating produce thickness, color distortion in the upper and lower surface of blade.
4, because the back pad awl of feeding is that line contacts with blade, and contact surface is big, is easy to generate coat and the phenomenon of filling up the awl bonding, the discharging difficulty, even cause product rejection, qualification rate is lower.
In sum, chemical Vapor deposition process of the prior art is produced loading appliance and the further improvement of production method thereof of coated chip.
Summary of the invention
The object of the present invention is to provide a kind of coated chip production with loading boat, it can satisfy the loading needs that chemical Vapor deposition process is produced coated chip, the advantage that have that stowage space is big, processing is simple, can reuse, loss is little improves production efficiency and the production capacity of cutter coat processing units.
