Abstract
The utility model discloses a processing crankshaft journal's multiple -cutting -edge car broach piece, include the blade body, set up cutter mounting hole on the blade body and be located the cutting edge on two knife faces of blade body, the blade body is flat blade body, all be equipped with a plurality of the same archs on two knife faces of blade body, every bellied top is the cutting edge, leaves the clearance between every two adjacent archs, the blade of cutting edge is higher than the surface in clearance. The utility model discloses a multiple -cutting -edge car broach piece, whole knife face within range have only cutting edge cutting part, owing to the clearance part is not cut, have consequently reduced the cutting force of multiple -cutting -edge car broach piece for multiple -cutting -edge car broach piece is difficult to collapse the sword, and processing is stable, simultaneously, the cutting is participated in simultaneously to a plurality of cutting edges of every knife face, has improved machining efficiency.
Description
Technical field
This utility model belongs to machine tooling cutter field, and in particular to a kind of many knife car broaching tools of machining crankshafts axle journal
Piece.
Background technology
In addition to using High Speed Milling Operation pin, also commonly used car draws processing technique for crankshaft journal roughing.Work is being drawn using car
The outer bowlder of skill machining crankshafts axle journal, generally first processes a undercut groove with grooving cutter (nonstandard circular arc blade) at present, then makes
With billmpse tool, knife feeds from this undercut groove, remaining position of processing excircles, but long processing time, and efficiency is low, and lathe tool holds
Easy tipping.If processed using wide knife car knife, efficiency can be improved, but cutting force is big, and easily be shaken, processing stability
Difference.
The content of the invention
The purpose of this utility model is aiming at the deficiency of above-mentioned technology, there is provided one kind reduces blade cutting force and adds apt
Many knife car broaching tool pieces of fixed machining crankshafts axle journal.
For achieving the above object, many knife car broaching tool pieces of the machining crankshafts axle journal designed by this utility model, including blade
Body, the Cutting tool installation manner hole being opened in the blade body and the blade on two knife faces of blade body, the blade
Body is flat blade body, and multiple identicals projections are equipped with two knife faces of the blade body, and each is described convex
The top risen is blade, and per gap is left between two neighboring projection, the cutting edge of the blade is higher than the surface in the gap.
Further, it is described equal per the gap width between two neighboring projection.
Further, first projection on the knife face is located at one end of the knife face, last on the knife face
The individual raised other end positioned at the knife face.
Compared with prior art, this utility model has advantages below：Many knife car broaching tool pieces of the present utility model, whole knife
There was only blade machined part in the range of face, because gap portion does not cut, therefore reduce the cutting force of many knife car broaching tool pieces, make
Much knife car broaching tool piece is not easy to collapse knife, and processes stable；Meanwhile, multiple blades of each knife face simultaneously participate in cutting, improve
Working (machining) efficiency.
Description of the drawings
Fig. 1 is many knife car broaching tool chip architecture schematic top plan views of this utility model machining crankshafts axle journal.
Wherein：Blade body 1, Cutting tool installation manner hole 2, knife face 3, blade 4, gap 5, surface 6, projection 7.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment.
It is illustrated in figure 1 many knife car broaching tool pieces of machining crankshafts axle journal, including blade body 1, blade sheet in the present embodiment
Body 1 is flat blade body 1, and the middle part of blade body 1 offers Cutting tool installation manner hole 2, two knife faces of blade body 2
Multiple identical projections 7 are equipped with 3, the top of each projection 7 is blade 4, and between every two neighboring raised 7 gap 5 is left,
And the cutting edge of blade 4 is higher than the surface 6 in gap 5.It is equal per the width of gap 5 between two neighboring raised 7 in the present embodiment, knife
First projection 7 on face 3 is located at one end of knife face 3, and last on knife face 3 raised 7 is located at the other end of knife face 3.
Plus man-hour, part along the circumferential direction rotates, and many knife car broaching tool pieces are moved radially after less distance, blade 4 with
Feature contacts again axial direction movement cut, and gap 5 not with feature contacts, not parameter cutting, i.e., blade 4 is relative to zero
Part outer surface is spinned motion, as long as part often rotates a circle, moves axially the width that speed is not more than each blade 4, so that it may
It is cylindrical with Continuous maching.
When part rotates, there was only the machined part of blade 4 in the range of whole knife face 3, because the part of gap 5 is not cut, therefore
Reduce the cutting force of many knife car broaching tool pieces so that many knife car broaching tool pieces are not easy to collapse knife, and process stable；Meanwhile, many knife cars
Broaching tool piece is moved along part axial, and blade continues to cut piece surface originally in interstice coverage, until whole completion of processing,
Multiple blades simultaneously participate in cutting, improve working (machining) efficiency.
