Description
Technical field
The utility model belongs to cutting-tool engineering field, is specifically related to a kind of slim cutter for cutting thin-wall copper pipe.
Background technology
The cutting of thin-wall copper pipe is processed by the cutter be installed on machine tool chief axis.In prior art, cutting thin-wall copper pipe generally adopts the cutter hub with bilateral shoulder to support the two-sided thicker blade of blade formation, blade is fixed by welding on cutter hub, and blade passes through the bearings of two series connection on machine tool chief axis, and is fixed by bearing enclose by nut.Its shortcoming is: one, the section closing in face of two-sided blade cutting thin-wall copper pipe formation is large, and endoporus is little, affects tube fluid flow; Two, during work, phase mutual friction inside two bearings, nut is near bearing outer ring simultaneously, thus limits the rotation of bearing, strengthens bearing drag, reduces its service life; Three, blade adopts bilateral shoulder, and by cutter hub and blade welding, processing technology is complicated, uses material many, wastes time and energy; Four, the duplex bearing adopting series connection installed by blade, complex structure, and be difficult to the center ensureing the edge of a knife, manufacturing cost is high.Therefore be necessary to propose to improve.
Utility model content
The technical problem that the utility model solves: a kind of slim cutter for cutting thin-wall copper pipe is provided, cutter hub and blade are made integral structure, blade is V-type one side cutting edge, and form ultrathin blade at cutter hub side convex shoulder, save and make material, reduce manufacturing cost, processing technology is simple, cutting copper pipe section is concordant, and section closing in area is little, and endoporus is large; And blade only adopts a bearings on main shaft, is fixed on bearing by collar by blade, makes blade and bearing outer ring be fixed as one, the problem that effective solution prior art middle (center) bearing frictional resistance is large, bearing rotates flexibly, and structure is simple, low cost of manufacture, extends bearing service life.
The technical solution adopted in the utility model: for cutting the slim cutter of thin-wall copper pipe, there is blade, described blade by bearings on machine tool chief axis, described blade comprises cutter hub and blade, described blade is located on cutter hub outer cylinder surface and is formed integral structure, the one side cutting edge of described blade to be cross section be V-type, described cutter hub side is provided with convex shoulder, the side, outer ring of described bearing is shaped with flange, the outer cylinder surface of described bearing outer ring is provided with draw-in groove, is fixed on bearing by blade after collar engages with draw-in groove.
Wherein, described collar is C type structure, and the inner side of described C type structure is provided with multiple groove.
Further, described blade adopts high hardness wear-resisting type carbide alloy to make.
The utility model advantage compared with prior art:
1, cutter hub and blade are made integral structure and blade is V-type one side cutting edge, and only at cutter hub side convex shoulder, it is made to form ultrathin blade, greatly save and make material, reduce manufacturing cost, processing technology is simple, its cutting copper pipe section is concordant, section closing in area is little, and endoporus is large, improves copper pipe internal flow flow;
2, blade adopts a bearings on main shaft, efficiently solves in prior art the problem using duplex bearing frictional resistance large, and bearing rotates flexibly, and structure is simple, low cost of manufacture, extends bearing service life;
3, blade side is fixed on bearing by collar, and opposite side is located by flange, and blade and bearing outer ring are fixed as one, and replaces nut fixed form in original technology, and it rotates more flexible, smart structural design, long service life.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-6, embodiment of the present utility model is described.
For cutting the slim cutter of thin-wall copper pipe, as shown in Figure 1, 2, have blade 1, preferably, described blade 1 adopts high hardness wear-resisting type carbide alloy to make, and described blade 1 is supported on machine tool chief axis by bearing 2.As shown in Figure 3,4, described blade 1 comprises cutter hub 11 and blade 12, described blade 12 is located on cutter hub 11 outer cylinder surface and is formed integral structure, the one side cutting edge of described blade 12 to be cross sections be V-type, described cutter hub 11 side is provided with convex shoulder 13, makes it form ultrathin blade, greatly saves and makes material, reduce manufacturing cost, processing technology is simple.As shown in Figure 5, the side, outer ring 21 of described bearing 2 is shaped with flange 23, the outer cylinder surface of described bearing 2 outer ring 21 is provided with draw-in groove 22, after collar 3 engages with draw-in groove 22, blade 1 is fixed on bearing 2, concrete, as shown in Figure 6, described collar 3 is C type structure, the inner side of described C type structure is provided with multiple groove 31, and groove 31 can increase the elastic bending of collar 3; 1, the utility model blade adopts a bearing 2 to be supported on main shaft, and efficiently solve in prior art the problem using duplex bearing frictional resistance large, bearing 2 rotates flexibly, and structure is simple, low cost of manufacture, prolongation bearing service life; Meanwhile, blade 1 side is fixed on bearing 2 by collar 3, and opposite side is located by flange 23, blade 1 and bearing 2 outer ring 21 is fixed as one, replaces nut fixed form in original technology, and it rotates more flexible, smart structural design, long service life.
As shown in Figure 1, 2, during installation, bearing 2 and blade 1 inner hole are set with, make blade 1 side be close to the flange 23 of bearing 2, collar 3 is stuck in draw-in groove 22 and is fixed by blade 1 opposite side, is then arranged on machine tool chief axis by the bearing 2 be fixed as one with blade 1; Use the thin-wall copper pipe of the utility model cutting, its cutting section is concordant, and section closing in area is little, is 1/3rd of prior art closing in area, increases endoporus, improves copper pipe internal flow flow.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
