Abstract
The utility model relates to a metal cutting tool for processing T-shaped grooves in the machining industry, in particular to a novel T-shaped milling cutter, which comprises a cutter head and a cutter arbor. The cutter head and the cutter arbor are integrally arranged to form a T shape, the cutter head comprises a plurality of spiral cutting portions, a chip removal groove is formed between each two adjacent cutting portions, each cutting portion comprises a side cutting blade and a bottom cutting blade disposed peripherally, and the outer end of each bottom cutting blade is connected with the corresponding side cutting blade. The novel T-shaped milling cutter can complete machining of a T-shaped groove at one step, omits tool changing, increases work efficiency and saves production cost.
Description
Technical field
The utility model relates to the metal cutting tool of machining T-shaped slot in a kind of mechanical processing industry, is specifically related to a kind of Novel T-shaped milling cutter.
Background technology
At present, the T shape milling cutter that everybody knows comprises monoblock type and two kinds of structures of carbide alloy welded type, no matter be monoblock type or welded type T shape milling cutter, when machining T-shaped slot, all adopt the side edge that axially is provided with to mill out T-slot, the sidewall precision of the T-slot that processes like this is guaranteed, but the precision of groove bottom but can not get guaranteeing, therefore the T-slot that causes processing does not meet required precision, the way that solves is exactly to need to change another cutter the bottom surface of T-slot is processed once more to reach the precision that needs, and has so just increased tool change time, loses time, reduce operating efficiency, also increased production cost.
The utility model content
At the problems referred to above, the purpose of this utility model provides a kind of Novel T-shaped milling cutter, and the processing that it can once finish T-slot need not tool changing, has improved operating efficiency, has saved production cost.
The technical scheme that realizes the utility model purpose is as follows:
Novel T-shaped milling cutter, comprise the cutter head, the handle of a knife that are wholely set into the T font, described cutter head comprises a plurality of spiral cutting portions, form chip area between the two adjacent cutting portions, described cutting portion comprises side cutting edge and the cutting shear blade that circumferentially is provided with, and the outer end of cutting shear blade is connected with the side cutting edge.Like this when machining T-shaped slot, by the side cutting edge two cell walls of T-slot are carried out milling, the cutting shear blade then carries out milling to the bottom land plane of T-slot, once just can finish the processing of T-slot.
Further, have at least the cutting edge of two cutting shear blades to extend to the center of cutter head in described a plurality of cutting portion.When Milling Process is carried out on the bottom land plane of T-slot, can not stay undressed position like this at the middle part.
Further, described cutting shear blade one side that extends to the cutter head center is provided with groove for cuttings.Extending to the bits that the extension sword at cutter head center mills out by the cutting shear blade so just discharges from groove for cuttings.
Further, be provided with the chip removal notch between the root of described two adjacent cutting portions, the bits that the cutting shear blade mills out are discharged smoothly from the chip removal notch.
Further, the quantity of described cutting portion is 4-6.
Adopted above-mentioned scheme, during machining T-shaped slot, by the side cutting edge two cell walls of T-slot are carried out milling, the cutting shear blade then carries out milling to the bottom land plane of T-slot, once just can finish the processing of T-slot, and groove for cuttings, chip removal notch can be discharged the milling bits, the milling bits can not occur and block, and influence the precision of machined surface.The utility model can once be finished the processing of T-slot, need not tool changing, has improved operating efficiency, has saved production cost.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Among the figure, 1 is cutter head, and 2 is handle of a knife, and 3 is chip area, and 4 is the side cutting edge, and 5 are the cutting shear blade, and 6 is groove for cuttings, and 7 are the chip removal notch, and 8 for extending sword.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, Novel T-shaped milling cutter, comprise the cutter head 1, the handle of a knife 2 that are wholely set into the T font, cutter head comprises 6 spiral cutting portions, form chip area 3 between the two adjacent cutting portions, cutting portion comprises side cutting edge 4 and the cutting shear blade 5 that circumferentially is provided with, and the outer end of cutting shear blade 5 is connected with side cutting edge 4.Wherein the cutting edge of the cutting shear blade of two symmetries extends to the center of cutter head, and cutting shear blade one side that extends to the cutter head center is provided with groove for cuttings 6, and the cutting shear blade extends to the bits that the extension sword 8 at cutter head center mills out and just discharges from groove for cuttings.Be provided with chip removal notch 7 between the root of two adjacent cutting portions, the bits that assurance cutting shear blade mills out are discharged smoothly from the chip removal notch.
