Referring to fig. 1-4, a welded-type jade-base milling cutter comprises a cutter head 1, a cutting part 2 is arranged on the cutter head, the cutter head 1 and the cutting part 2 are integrally formed, the cutting part 2 comprises a cutting edge part and a bottom edge 20 positioned at the bottom of the cutting edge part, and the cutting edge part comprises a cutting edge 211 and a cutting groove 210. The bottom edge 20 is a cone with gradually increased outer diameter formed by an irregular right-angled triangle rotating along a right-angle side coincident with the center line of the cutter, and the hypotenuse of the irregular direct triangle is formed by sequentially connecting straight lines and arc lines end to end. The design is corresponded to the pattern or decorative pattern that the appearance of end sword 20 carried out sculpture as required, makes the cutter can the complicated curved surface of one shot forming wooden furniture, and in this embodiment, right angled triangle's hypotenuse is the complicated curved surface that comprises straight line and pitch arc, and the decorative pattern and the pattern of convenient milling process out wooden furniture need not make a round trip to change the cutter and process, improves machining efficiency, guarantees the machining precision.

In this embodiment, the right triangle is composed of two legs and a hypotenuse, and for convenience of description, the hypotenuse is defined as the irregular leg, and the bottom edge 20 participating in cutting is actually formed by the irregular leg of the right triangle after 360 ° rotation. According to the actually processed pattern or pattern, the irregular edge can be formed by only sequentially ending and connecting a plurality of straight lines or a plurality of arc lines, and different patterns and patterns can be carved according to the shape of the irregular edge without being limited to the shape.

As a preferred embodiment of the present invention, it may also have the following additional technical features.

In this embodiment, blade portion shear angle is 0, the chip removal of being convenient for to improve cutter chip removal effect.

In this embodiment, the axial relief angle of sword oral area is 18, and the radial relief angle of sword oral area is 15, and the cutter relief angle is the contained angle between flank and the cutting plane, and the setting of relief angle directly influences the quality, the cutter incorruptibility and the productivity of machined surface, and the effect of relief angle is the friction that reduces cutter flank and machined surface in the cutting process, and the relief angle can not too big, should not too little yet. The relief angle increases, can reduce the friction, avoids the work piece, improves the machined surface quality, but when the relief angle increases, its tool bit intensity is low, and the heat dissipation is small, and the relief angle is too small, adds the work piece that can not in time avoid in processing, influences machined part surface quality, aggravates cutter wearing and tearing. The material characteristic and continuous experiment of processing as required, the machined part that avoids that setting up of radial back angle and axial back angle can be better in this embodiment improves work piece surface quality, and the back angle can assist the discharge saw-dust simultaneously, reduces cutter wearing and tearing, guarantees that the timber surface that is milled is smooth, does not have the barb.

In this embodiment, the bottom blade 20 is made of tungsten steel, which has high hardness, good wear resistance, good strength and toughness, and excellent heat resistance and corrosion resistance, and the manufactured cutting tool has the advantages of high hardness, high strength, high wear resistance, and the like, except for the bottom blade 20, other parts of the cutting head 1 are made of white iron or stainless steel, and when the tungsten steel bottom blade 20 reaches the normal service life, the stainless steel or white iron cutting head 1 can be reused, thereby saving resources and reducing the manufacturing and using costs.

Like figure 5, in this embodiment, the afterbody detachable of tool bit 1 is connected with the handle of a knife of adjustable length, and tool bit 1 can be dismantled with the handle of a knife and be connected, uses in a flexible way, the operation of being convenient for, and the handle of a knife exists as a connecting piece, and length sets to the adjustable, has increased application scope.

In this embodiment, protruding elastic pressing block 10 that is equipped with of tool bit 1 circumference, elastic pressing block 10 is through inlaying on the spring coupling in the outer wall of tool bit 1 periphery in tool bit 1, elastic pressing block 10 atress can indent in the outer wall of tool bit 1, the handle of a knife end of being connected with tool bit 1 is equipped with the tool bit holding chamber 32 that is used for holding tool bit 1, this tool bit holding chamber 32 inner wall is equipped with the briquetting holding chamber 30 that holds elastic pressing block 10, this tool bit holding chamber 32 outer wall is equipped with the top that is used for pushing up elastic pressing block 10 and moves passageway 31, briquetting holding chamber 30 and top move passageway 31 intercommunication. Elastic pressing block 10 is the wedge, and the inclined plane is just to handle of a knife tip, and when handle of a knife and tool bit 1 cooperated, tool bit 1 inserted and locates in the tool bit holding chamber 32 of handle of a knife, and the handle of a knife end pushes elastic pressing block 10's inclined plane, makes it indent in tool bit 1 periphery wall, and when briquetting holding chamber 30 arrived elastic pressing block 10 position, elastic pressing block 10 was launched in briquetting holding chamber 30 by the spring action, realizes the location of tool bit 1 and handle of a knife. When the positioning relation between the elastic pressing block and the handle needs to be released, the elastic pressing block 10 is pushed, and then the handle is quickly retracted.

The detachable connection mode has the advantages of simple structure, convenient disassembly and low manufacturing cost. The detachable connection may also be a threaded connection, a riveted connection, a pinned connection, etc., and is not limited herein.
