Abstract
" energy-efficient trepanning tool " of the invention, it is made of " indexable to reface machine holding carbide alloy blade " (1), trepanning tool cutter hub (2), bolt (3), it is characterized in that, blade (1) directly clamping is convenient for mounting and clamping on the cutter head of cutter hub (2).Blade (1) can grind corresponding geometric angle degree and Volume bits slots according to machined material.Chip breaking, chip removal are smooth, and stock-removing efficiency is high, and blade (1) can be refaced repeatedly, save cemented carbide material.
Description
First, technical field
" energy-efficient trepanning tool " of the invention, as shown in Figure 1, it is by blade (1), cutter hub (2), bolt (3) institute group
Into suitable for processing various metal materials, belonging to machining field of tool.
2nd, background technology
Enterprise's used trepanning tool in terms of deep hole machining at present, blade (1) be first clamping on a small knife bar, so
Afterwards again by small knife bar clamping on the cutter hub (2) of trepanning tool, blade (1) is the machine holding carbide alloy blade of indexable throw away,
As shown in attached drawing 2, attached drawing 3.
The blade (1) of above-mentioned trepanning tool with the positioning of small knife bar is come by the cutting edge of blade (1) and the side of small knife bar
Positioning, so cannot reface, gap is produced with small knife bar once refacing blade (1), as shown in Figure 4.
The cutter hub (2) of above-mentioned trepanning tool is complicated, and cost of manufacture is high, and indexable throw away machine holding carbide alloy blade
(1), it indexable can only use, it is impossible to reface, with being eliminated several times, waste is very big.
The above-mentioned indexable and carbide chip (1) that cannot reface, the cutting edge of blade (1) cannot be according to being processed
Material grinds corresponding geometric angle and Volume bits slots, so it is difficult to ensure that chip breaking, cutting resistance is big, stock-removing efficiency is not high.
3rd, invention content
" energy-efficient trepanning tool " of the invention has been invented novel " indexable to reface carbide chip (1) ", special
Point is the small column for having positioning in the bottom of blade (1), as shown in Figure 5.
" energy-efficient trepanning tool " of the invention, simplifies trepanning tool cutter hub (2) structure, blade (1) is directly installed in cutter hub (2)
(cutter head) on, have in the plane of fixturing blade (1) (cutter head) match with blade (1) bottom small column and small blind hole as schemed
Shown in 6.
" energy-efficient trepanning tool " of the invention, the cutting edge of blade (1) is flat sword, can basis
4th, it illustrates
Attached drawing 1 is " energy-efficient trepanning tool " assembling schematic diagram of the invention.(cutter head) on attached drawing is trepanning tool cutter hub (2)
On " cutter head ", the quantity of (cutter head) is depending on the size in part to be processed aperture.
Attached drawing 2 is existing trepanning tool, and blade elder generation clamping shows on small knife bar, then by structure of the small knife bar clamping on cutter hub
It is intended to.
Attached drawing 3 is existing trepanning tool, and blade elder generation clamping on small knife bar, then by small knife bar clamping tie on cutter hub by another kind
The schematic diagram of structure.
Attached drawing 4 is existing trepanning tool, blade and the structure diagram of cutter hub cooperation, and imaginary line represents that blade refaces rear knife
The gap generated between piece and cutter hub.
Attached drawing 5 is the schematic diagram of four kinds of blade shapes used in " energy-efficient trepanning tool " of the invention.
Attached drawing 6 is that of the invention " energy-efficient trepanning tool " be that fixturing blade (1), four small blind holes on cutter hub (cutter head) are illustrated
Figure.
Attached drawing 7 is of the invention " energy-efficient trepanning tool ", tetra- kinds of blade cut swords of A, B, C, D cut chip h1 ', h2 ', h3 ',
H4 ' points of bits situation schematic diagrams.
Attached drawing 8 stretches out the schematic diagram of the amount of cutter head for blade.
5th, specific embodiment
Of the invention " energy-efficient trepanning tool " divides bits formula to cut using ladder, during tetra- blade cuts of A, B, C, D, A blades
Workpiece is initially cut, the chip width that it cuts is h1, that is, A blade cut swords h1Width, subsequent blade B incision, it cuts
Lower two small h2Chip, h2As B blade cuts tread degree h2Cut A blade cut tread degree h1Half, with such
It pushes away, is finally blade D incision workpiece, it cuts two small chips as h4As shown in Figure 7.
The blade (1) of " energy-efficient trepanning tool " of the invention all can be refaced repeatedly, the number refaced and blade (1)
The amount for stretching out (cutter head) is related, it is assumed that it is " M " that blade, which stretches out the amount of refacing that the amount of (cutter head) is " W " and blade is averagely each, then
This blade refaces number as N=W/M, and N is refaces number, as shown in Figure 8.
A piece of new D blades, start can indexing can be refaced again with twice, after abrasion " N " it is secondary, can will then after wearing
It, which changes, wears into C blades, then makes B blades into again after wearing, and finally makes A blades into, make into A blades on trepanning tool cannot the used time,
Not reusable A blades can also be made to the machine holding carbide alloy blade of square into, on other mechanical clamped cutting tools.
In conclusion " energy-efficient trepanning tool " of the invention, not only chip removal is unobstructed, and stock-removing efficiency is high, and can save again
A large amount of cemented carbide material.
Indexable machine holding carbide alloy blade (1) of refacing is manufactured by cemented carbide works, and jacking cutter hub (2) is by being machined
Tools factory manufactures.
