New description: [New technical field] This creation involves a combination of a small and medium-sized drill with different shank and blade, and the combination of the shank and the blade. [Prior Art] For general industrial processing, high-speed drills such as drills or milling cutters, the diameter of which is less than 6 kW, the repairer 'dare to use stainless steel to cut and form one piece. 'The medium and small tools of this kind are poor in rigidity and hardness, so The service life is short, so the expensive Hegang Steel Pipe is used to make the full-length tool. However, it is a pity that the use of the bit money knife will cause the sentence to be discarded with the 'clamp part. Increasing costs. In order to touch the ship's full support Lin Gang secret steel material or the milling cutter in the durability〗 The lack of cost 'the third sun _- kinds of conventional modified drill milling cutter, will not be divided into the shank A and the blade B two parts, in which the shank A is made of cheaper steel or material, and the blade B is made of high strength and expensive Hegang steel material; the knives are first in the shank A - End drilling - money, the inner diameter of the hole A1 is slightly smaller than the outer diameter of the length of the crane steel rod-end of the blade, when the shank is combined with the crane steel rod, the knife is first; At the same time, the aperture is expanded in the shaft of the shaft, and then the groove of the H-handle is filled with the hole A1. The front end of the steel bar is formed with a snail; ', so that the shank ^ knife 77 w is the same - drill or milling cutter . Narrow,! The simple nano- __ added in the three figures shows that the change in the size of the money is due to the fact that the M320930 prime's and the external non-axis shank and the sharp-edged fine knives are different metals respectively, resulting in different swell coefficients. Sliding and loosening. Therefore, another conventional cutter structure shown in the fourth figure provides a structure in which the shank is combined with the cutter knives, and the shank A is also a single steel or a relatively inexpensive secondary material. The blade B is a crane steel bar, and the joint between the shank and the blade is combined by brazing. However, the butt-welded tool is docked because it needs to use the same straight steel control as the tool holder. Therefore, it is not only time-consuming and power-consuming to waste a large amount of material when grinding a small-diameter blade. The crane steel material; in addition, the butt-welded structure is very insufficient to withstand the radial vibration of the side, and can not provide the sharp knife effective support force 0 [New content] This is the purpose of the secret touch knife to cut off the knife The combination of the leaking man's tight fit and the shank and the knife continue to be brazed. • The main feature of this creation is that it combines the plug-in pressing fit and the brazing method to make the knife-reading shank more in-line, in order to solve the problems of the above-mentioned tool holder and knife. . The technical means of this creation include a knife made of a single-steel material made of a shank steel material, the end of the tool holder-axial extension-depth hole, the hole is filled with a proper amount of brazing material; 7 blade The mating part of the end extends the hole and the form is matched, and the light temperature is applied to the shank to complete the welding process 'air (four) hard material (four) (four) gang * Kongshe together. , mouth 6 M320930 The tool phase and the edge of the tool are used by welding and tight fitting, which can provide the phenomenon that the high/dishback speed is not slipped when it is added, and because of the use of small diameter steel bars, it saves The advantage of expensive material consumption, and because it is a plug-in welded structure, it can avoid the occurrence of cracks due to vibration during machining, and therefore, the shank and the edge of the blade, δ, , , . The structure is super strong, the handle of this creation uses stainless steel, which has the lowest cost, and the blade uses small straight I crane steel material without using grinding to make the diameter thinner, so adding jade is the most time-saving and labor-saving and the whole Compared with the tool of Hegang Steel, the cost is lower. [Embodiment] The embodiments of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification. As shown in the figure-figure and the second figure, the small and medium-sized hard-f alloy tool structure provided by this creation includes the - shank 1 and the blade 3, wherein the shank can be made of steel or other cost and strength. Made of a suitable secondary material, the shank is a cylindrical body, one end of which axially extends a depth of hole 11 〇 - the preferred embodiment of the cutting edge 3 is more expensive and more durable and durable Manufactured from a high-tungsten steel material, the cutter 3 is a cylindrical crane steel rod extending a length before being combined with the shank shank. The two ends of the crane steel rod are respectively formed to have a length to fit the hole 11 The mating portion 32' and the length portion are used as the blade portion 31 forming the spiral groove; the mating portion 32 and the hole 11 have a tight fit to each other. Before the insertion portion 32 is inserted into the hole 11, the shank 1 is appropriately heated to expand the hole 11 by thermal expansion, and then an appropriate amount of brazing filler 2 is placed in the hole 11, and the brazing filler M320930 = silver copper The material may also be other suitable materials; when the brazing filler 2 is placed in:, the mating portion 32 of the crucible is inserted into the hole 11, and then the position of the holder corresponding to the hole = is heated to 'make the hole u _ brazing_ Melt, to properly cool the J. 4 32 production and forced to cooperate, turn the (four) and the handle to turn the effect. This is only for the use of the release of the book _ read good _, Lin Qi map according to the second =::: including: ^ More S should still be included in the scope of this creative intention protection. M320930 [Simple description of the drawing]. The first figure shows a plan sectional exploded view of the structure before the tool holder and the blade are not combined. The second figure is a plan sectional view showing the structure of the combination of the shank and the blade of the present invention. The third figure shows a plan cross-section showing the conventional shank and the blade in a simple insertion and tight fit. The fourth figure shows the plane culvert of the conventional shank as the butt joint. [Description of main component symbols] ι·····Knife handle 11...
