Abstract
The utility model provides a trilateral sword milling cutter of combined type carbide straight -tooth, the cutter body is fixed in on the blade disc through spring fastening screw. Spring fastening screw is with flexonics fixed cutter body and blade disc to blade disc dispersion cutting resistance is favorable to improving blade cutting strength, avoids the blade fracture. Simultaneously, because the cutter body can be dismantled, be convenient for repair, change, be favorable to lengthening the life of blade disc, reduction in production cost.
Description
Technical field
This utility model is related to machining technology field, more particularly to a kind of three face sword milling of Combined hard straight-tooth
Knife.
Background technology
The blade of face and side milling cutter with straight teeth is 90 ° of positive angle tetragons, and its blade exposure amount is big, high in machining efficiency, while
There is the defects such as big processing resistance, tool wear weight, easy tipping or breaking.
In prior art, blade and cutterhead are fixed using welding manner more.But rigid connection is welded as, when blade exists
When being subject to larger resistance during cutting, this rigid connection hinders dispersion of the resistance to cutterhead, so as to aggravate blade local pressure,
And inspire fracture.Meanwhile, impaired blade is difficult to be repaired in cutter body, and due to welding manner bonding strength it is higher,
It is not easy to accurate taking-up.Thus, existing welding type face and side milling cutter with straight teeth often causes cutter hub entirety because of the damage of a small amount of blade
Scrap, waste serious.
Utility model content
This utility model provides a kind of Combined hard face and side milling cutter with straight teeth, to solve above-mentioned prior art not
Foot.By spring trip bolt to be flexibly connected fixed cutter body and cutterhead, so that cutterhead disperses cutting resistance, be conducive to improving knife
Piece cutting hardness, it is to avoid blade breakages.Simultaneously as cutter hub is detachable, it is easily repaired, changes, is conducive to extending making for cutterhead
With the life-span, production cost is reduced.
In order to realize the purpose of this utility model, intend using following technology：
A kind of Combined hard face and side milling cutter with straight teeth, it is characterised in that cutter hub is fixed by spring trip bolt
On cutterhead, the cutter hub is fixed on knife support front by soldering by carbide blade and constitutes, and the cutterhead includes cutting disc
Tower, knife bed and draw-in groove, the cutter hub are vertically arranged in the draw-in groove, and the spring trip bolt is by opening up in the knife bed
The binding groove that arranges with the knife support back side of hole clipping be connected to a fixed.
Further, the single cutter hub is fixed by least individual spring trip bolt.
Further, the knife support width is equal with the knife tower thickness.
Further, width of the width of the knife support less than the carbide blade.
The beneficial effects of the utility model are：
1st, this utility model passes through spring trip bolt to be flexibly connected fixed cutter body and cutterhead, so that cutterhead dispersion is cut
Resistance, is conducive to improving blade cut intensity, it is to avoid blade breakages.
2nd, this utility model cutter hub is detachable, is easily repaired, changes, and is conducive to extending the service life of cutterhead, reduces life
Produce cost.
Description of the drawings
Fig. 1 shows this utility model structural representation.
Fig. 2 shows this utility model structural representation in an embodiment.
Specific embodiment
As shown in figure 1, a kind of Combined hard face and side milling cutter with straight teeth, cutter hub 1 is fixed by spring trip bolt 3
On cutterhead 2.The spring trip bolt 3 to be flexibly connected the fixation cutter hub 1 and the cutterhead 2, so as to 2 points of the cutterhead
Scattered cutting resistance, is conducive to improving the cutting hardness of the cutter hub 1.
The cutter hub 1 is fixed on knife support 20 front by soldering by carbide blade 10 and constitutes.The cutter hub 1 it is independent with
It is processed outside the cutterhead 2, is easy to operation, and advantageously ensures that machining accuracy.
The cutterhead 2 includes cutting disc tower 30, knife bed 40 and draw-in groove 50.30 periphery of cutting disc tower carries the cutter hub
After 1, it is fixed in milling machine by 30 center positioning hole of cutting disc tower.The knife bed 40 is with the cutting disc tower 30 using high
The hard steel such as fast steel are integrally formed, and are conducive to increasing resistance diffusional area, and improve by force intensity.
The cutter hub 1 is vertically arranged in the draw-in groove 50.The draw-in groove 50 is used to quickly position the cutter hub 1, and
During the cutting stress of the cutter hub 1, auxiliary is provided and compresses positioning, it is ensured that cutting precision.
The spring trip bolt 3 is tight with what 20 back side of knife support was arranged by the hole clipping 60 opened up in the knife bed 40
Gu groove 70 is connected to a fixed.The carbide blade 10 reaches resistance at the knife support 20 in cutting.Microstructure
In, the knife support 20 is sunk in stress concentration site, drives mirror image site to upwarp, elongates the spring trip bolt 3 at this,
So as to active force is reached after the knife bed 40, it is dispersed in the cutting disc tower 30.
The single cutter hub 1 is fixed by least 3 spring trip bolts 3.Using the more spring
Trip bolt 3 is attached, and is conducive to strengthening bonding strength and increases resistance transmission site.
20 width of knife support is equal with 30 thickness of knife tower.It is easy to Fast Installation.
Width of the width of the knife support 20 less than the carbide blade 10.It is easy to process three face swords.
As shown in Fig. 2 in one embodiment, the cutterhead 2 is processed using high-speed steel integrated die-casting；Using high frequency brazing machine
Process the cutter hub 1.
The spring spool of the spring trip bolt 3 is put in 60 long nose end of the hole clipping, screw is inserted from the other end.Will
Vertically card is put in the draw-in groove 50 cutter hub 1.The spring trip bolt 3 is screwed successively using instrument, makes the knife support
It is close to the right-angle surface of the knife bed 40 in 20 back sides.Complete assembling of the single cutter hub 1 on the cutterhead 2.
Assembled after cutter hub 1 described in 24 groups successively according to above-mentioned steps, complete milling cutter assembling.
After finding to have the carbide blade 10 of damage, it is only necessary to unscrew the corresponding spring trip bolt 3 and tie
The annexation for releasing the corresponding knife support 20 and the knife bed 40 is closed, the cutter hub 1 of damage, Replacement and Repair or new are taken out
The cutter hub 1.
Due to 1 simple structure of the cutter hub, it is easy to clamp, thus can repair to damaging the lighter cutter hub 1.
And only waste treatment is carried out to damaging the heavier cutter hub 1.
