Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of transformation of the way cutter that is used for Digit Control Machine Tool.
Background technology
Along with the application of Digit Control Machine Tool more and more widely, the use amount of blade is increasing, there is the blade of scrapping after a lot of the use in the workshop.As shown in Figure 1, what use knife bar 10 employings at present is the level type structure, and dress is with D type (55 °) blade 2, and what generally use is the A point of a knife 21 of blade 2, and B point of a knife 22 does not just use to be scrapped because of 21 wearing and tearing of A point of a knife; Use at present knife bar 10 structures special, can not improve on knife bar 10 bases and make full use of A point of a knife 21 and B point of a knife 22 using at present.As shown in Figure 2, discarded knife bar 100 dresses are with S type blade, and S type blade has not been used at present, and discarded knife bar 100 but is intact, and abandoning has not only wasted resource, has also increased production cost.
The utility model content
The purpose of the utility model is to use the tool structures defective to existing Digit Control Machine Tool, and a kind of transformation of the way cutter is provided, and improves the utilization rate of cutter, reduces production costs.
For achieving the above object, the technical problem that the utility model will solve is: a kind of transformation of the way cutter is provided, it is characterized in that comprising knife bar, blade, edge bearing; Said knife bar lower end is a burnishing surface; Said knife bar lower end burnishing surface one side is provided with 125 ° of orientation angles; Said knife bar lower end burnishing surface is provided with the housing screw installing hole; Said blade is provided with A point of a knife and B point of a knife; Said blade clamping is on the burnishing surface of knife bar lower end, and the B point of a knife and is provided with edge bearing between blade and the knife bar and is connected with housing screw and compress vertically downward.
The thickness of said edge bearing is not less than 12mm, and width is not more than 25mm.
Because this transformation of the way cutter makes full use of discarded knife bar and discarded blade, not only improved the utilization rate of cutter, also reduced production cost.
Description of drawings
Fig. 1 uses the tool structures sketch map at present.
Fig. 2 is discarded tool structures sketch map.
Fig. 3 is transformation of the way tool structures sketch map.
Fig. 4 be among Fig. 3 A part along the B-B line cutaway view.
Use knife bar wherein, 10, at present; 100, discarded knife bar; 1, knife bar; 2, blade; 21, A point of a knife; 22, B point of a knife; 3 edge bearings; 23 housing screws.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is carried out detailed description.
Like Fig. 2 and shown in Figure 3, this transformation of the way cutter comprises knife bar 1, blade 2, edge bearing 3; Knife bar 1 lower end is a burnishing surface; Knife bar 1 lower end burnishing surface one side is provided with 125 ° of orientation angles; Knife bar 1 lower end burnishing surface is provided with the housing screw installing hole; Blade 2 is provided with A point of a knife 21 and B point of a knife 22; Blade 2 clampings are on the burnishing surface of knife bar 1 lower end, and B point of a knife 22 and is provided with edge bearing 3 and is connected with housing screw 23 and compress vertically downward between blade 2 and the knife bar 1.The thickness of edge bearing 3 is not less than 12mm, and width is not more than 25mm.
Knife bar 1 is to utilize discarded knife bar 100 shown in Figure 2 (to adorn with S type blade; Orientation angle is 90 °) lower end mills out a burnishing surface and makes; Burnishing surface one side milling goes out 125 ° of location angles with the needs of satisfied dress with D type blade 2 (55 °), and makes the housing screw installing hole so that dress housing screw 23 in the burnishing surface tapping.
Transformation of the way cutter is compared with present use cutter, and tool cutting edge angle and auxiliary angle all do not change, and has increased the intensity and the rigidity of cutter; The anterior angle of transformation of the way cutter from-2 ° ~ 3 ° of present use cutter become+2 ° ~ 3 °, transformation of the way cutter is sharper keen.Iron filings are got rid of from the tailstock direction, eliminated iron filings to cutter and workpiece machining surface extrusion friction, have both guaranteed the quality requirement of workpiece machining accuracy, surface roughness, have reduced the influence because of heat in metal cutting blade 2 again.B point of a knife 22 after utilize improving can converted products 150 surplus, roughness is Ra1.6 ~ 3.2 μ m, can satisfy common processing request fully.
It is to be noted that the above only is the preferred implementation of the utility model; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Be easy to the utility model is carried out some improvement and modification, these improvement and modification also fall in the protection domain of the utility model claim.
