The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model:
Please refer to the process tool decomposing schematic representation that Figure 2 shows that the utility model one embodiment, Figure 3 shows that the process tool generalized section of the utility model one embodiment, as shown in Figures 2 and 3, process tool comprises a blade part 10 and a handle of a knife section 20, blade part 10 comprises cutting blade 11 and a fixed part 12, fixed part 12 is arranged at the rear end of cutting blade 11, and the front end face of handle of a knife section 20 arranges a groove 21 with first depth H.Fixed part 12 is inserted in the groove 21 of handle of a knife section 20, and the degree of depth that fixed part 12 is inserted in groove 21 is the second degree of depth h, and the ratio of the second degree of depth h and the first depth H is 0.75～0.95.
Above-mentioned explanation continues, blade part 10 materials are tungsten carbide, and the cutting blade 11 of blade part 10 can be drill lip structure or milling cutter construction, in an embodiment, the fixed part 12 of blade part 10 rear ends is round bar shape, and the diameter of fixed part 12 is greater than the diameter of cutting blade 11, and the free end edge 13 of fixed part 12 can be processed as circular shape or lead angle shape.The material of handle of a knife section 20 is stainless steel, and the shape of the groove 21 corresponding fixed parts 12 of handle of a knife section 20, and the internal diameter of its further groove 21 (aperture size) is less than diameter 0～20 μ m of fixed part 12.
When fixed part 12 inserts groove 21, utilize free end edge 13 shapes in the arc-shaped of fixed part 12 or the design of straight line lead angle shape, center with auxiliary alignment indentation 21, the recycling pressurizing unit directly pushes fixed part 12 and be pushed in the groove 21, makes handle of a knife section 20 and blade part 10 closely chimeric.
Wherein, but be socketed on the holding capacity of groove 21 in order more to strengthen fixed part 12, the leading portion of handle of a knife section 20 forms front end face on an one day narrow conical neck 22 gradually, namely forms the conical neck 22 in forward end reduction of area footpath on one day, and the outer surface 23 that conical neck 22 front ends and fixed part 12 join is circular-arc.The outer surface 23 of conical neck 22 is circular-arc design can increase blade part 10 suffered cutting force radially, and increases the fixing polarization that blade part 10 is socketed on handle of a knife section 20.Compared to the conventional tool structure, handle of a knife of the present utility model section is circular-arc design with the outer surface 23 of conical neck 22 front ends, can improve that the conventional knives blade cuts, during grinding operation, easily produce that stress is concentrated and the disappearance of bursting apart, and then the cutting ability of efficient hardening process tool integral body.
On the other hand, outer surface at cutting blade 11 can coat a coating layer (not shown), the material of coating layer is metallic compound, carbon compound or the mixture that is comprised of above one-tenth branch, wherein the material preferably of metallic compound is titanium nitride (TiN), TiAlN (TiAlN), and the material preferably of carbon compound is diamond coating film (Diamond Coating) or class diamond coating film (Diamond like Coating).
In the utility model, owing to having one between the first depth H of the second degree of depth h of fixed part 12 groove that inserts 21 and groove 21 between 0.75～0.95 ratio, that is groove 21 section 12 that is not fixed fully is full of, consider the space to be worth doing and still reserve a plug, and then can hold because of fixed part 12 and push when being squeezed to groove 21, some metal fillings that the inwall of groove 21 and fixed part 12 phase mutual friction produce, and have better making acceptance rate.
In sum, process tool of the present utility model, the groove by handle of a knife section are not full of and still reserve the design in a plug bits space fully by blade part, promote the acceptance rate of process tool; And utilize the circular-arc conical neck of handle of a knife section leading portion, the cutting ability of efficient hardening process tool integral body.
The above only is the schematic specific embodiment of the utility model, is not to limit scope of the present utility model.Any those skilled in the art, the equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
