Abstract
Disclosed is a backward -fall chip knife for planing the T-shaped groove of steel parts, which is composed of a knife head, a knife body and a knife neck. The invention is characterized in that the face of the knife head will be planed an angle according to a triangle from one side of a blade to the outer side of the knife head and the bottom of the knife head, which will form a backward -fall chip inclined plane. The top point of the triangle planed angle is located on the outer side of the knife head and the edges of the bottom of the knife head. When the knife head of the invention advances, the backward- fall chip can be directly formed, which avoids the effect that the cut chip accumulates on the face of the knife head, assures the smooth processing of the T-shaped long groove and effectively lowers the damaging rate of the knife head. And thus the invention improves the processing precision and the production efficiency, reduces the processing cost and lowers the labor intensity of the operators.
Description
Technical field
The present invention relates to cutter, more specifically saying so is used for machined steel material on planer, especially drives the cutter of full through type T type groove on metal-planing machine for large-scale steel part.
Technical background
At present, processing steel part T type groove on planer, employing be to be the tack cutter of material with the carbide alloy, just the front of cutter is the plane, along with cutter head is pushed ahead, constantly goes out bits in the front.The problem of the existing maximum of this form is, big because of the cutter head volume on the one hand, be difficult to going in the straight trough, on the other hand, in the processing of " T " elongated slot, ever-increasing smear metal is deposited in the front of cutter head, makes the propelling of cutter head more and more difficult, even can not continue processing, also so greatly increased the cutter head spoilage, tool changing is frequent, and labor intensity of operating staff is big, processing cost is high, production efficiency is low, dimensional accuracy is difficult to control, and outward appearance is difficult to the requirement of ensuring the quality of products.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of steel element T-shaped groove processed on planer backward chip-turning-over knife is provided, make when cutter head is pushed ahead, turn over bits after directly forming, avoid the accumulation of smear metal, guarantee that the processing of "T"-shaped elongated slot is smooth, reduce the cutter head spoilage in the cutter head front, thereby improve machining accuracy, enhance productivity, cut down finished cost, and alleviate labor intensity of operating personnel.
The technical scheme that technical solution problem of the present invention is adopted is:
The present invention digs and turns over the bits cutter behind the steel part T-shape groove and be made of cutter head, cutter hub and cutter neck three parts.
Design feature of the present invention is the front at described cutter head, from blade place one side, to cutter head lateral surface and head base surface, presses the triangle top rake, turns over the bits inclined-plane after the formation, and the summit of triangle top rake is positioned on the seamed edge of cutter head lateral surface and head base surface.
Design feature of the present invention also is:
Blade has cutting edge inclination backward from top to bottom.
After turn over bits the inclined-plane be the arcwall face of indent on the direction to the cutter head lateral surface from blade at it.
Head base surface is acclivitous from blade at it on the direction to the cutter head lateral surface.
Between cutter hub and cutter neck, and between cutter neck and cutter head, adopt the transition of " R " type to be connected.
Cutter head is a material with W18Cr4V or W9 Cr4V2.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is when cutter head is pushed ahead, make the iron filings that cut out behind the cutter head front, turn over the bits inclined-plane and turn over bits backward, greatly reduced the smear metal resistance, and, made processing no longer be subjected to the restriction of "T"-shaped slot length along with turning over the smear metal temperature of taking away fast on the blade behind the iron filings.
2, the present invention greatly reduces the spoilage of cutter head, improves machining accuracy, enhances productivity, cuts down finished cost, and alleviate labor intensity of operating personnel.
Description of drawings:
Fig. 1 is a perspective view of the present invention.
Fig. 2 is that the B of Fig. 1 is to view.
Fig. 3 is that the E of Fig. 1 is to view.
Fig. 4 is that the A of Fig. 1 is to view.
Fig. 5 is that the C of Fig. 1 is to view.
Number in the figure: turn over the bits inclined-plane after 1 cutter head, 2 cutter hubs, 3 cutter necks, 4 blades, 5 cutter head lateral surfaces, 6 head base surface, 7.
Below by the specific embodiment, the invention will be further described in conjunction with the accompanying drawings:
The specific embodiment:
Referring to Fig. 1, present embodiment is made of cutter head 1, cutter hub 2 and cutter neck 3 three parts.
Shown in Figure 4, between cutter hub 2 and cutter neck 3, and between cutter neck 3 and cutter head 1, adopt the transition of " R " type to be connected the drag in the time of can effectively increasing smear metal.
Fig. 1, Fig. 3 and shown in Figure 5 in the front of cutter head 1, from blade 4 places one side, to cutter head lateral surface 5 and head base surface 6, press the triangle top rake, turn over bits inclined-plane 7 after the formation, and the summit 8 of triangle top rake is positioned on the seamed edge of cutter head lateral surface 5 and head base surface 6.
Shown in Figure 2, blade 4 has cutting edge inclination backward from top to bottom, and this cutting edge inclination size is adjusted according to the difference of processed material, can be set to 15 ° or about 15 °.
Shown in Figure 3, after turn over bits inclined-plane 7 be the arcwall face of indent on the direction to cutter head lateral surface 5 from blade 4 at it.
Shown in Figure 4, head base surface 6 is acclivitous from blade 4 at it on the direction to cutter head lateral surface 5.
In concrete the enforcement, cutter head is a material with W18Cr4V or W9 Cr4V2.
