Abstract

The utility model discloses a T-shaped groove rearward overturning chip cutter of a plane steel part, consists of three parts of a cutter head, a cutter body and a cutter neck and is characterized in that a triangular cutting angle is cut to an external side and the bottom surface of the cutter head from the side of a cutter edge on the front side of the cutter head, thus forming a rearward overturning chip inclined plane; the vertex of the triangular cutting angle is positioned on the edge of the external side and the bottom surface of the cutter head. When pushing forward, the cutter head can directly form the rearward overturning chip so that the chip cutter avoids the accumulation of chips on the front side of the cutter head, ensures the smooth processing of a T-shaped elongated slot and effectively reduces the damage rate of the cutter head, thus improving the processing precision, reducing the processing cost and reducing the labor intensity of operators.

Description

Steel element T-shaped groove processed on planer backward chip-turning-over knife

Technical field

The utility model relates to cutter, more specifically says so to be 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.

The utility model content

The utility model 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 the utility model technical solution problem is adopted is:

Turning over the bits cutter behind the utility model plane steel part T-shape groove is made of cutter head, cutter hub and cutter neck three parts.

Design feature of the present utility model 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 utility model 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 W9Cr4V2.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model 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 utility model 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 the utility model perspective view.

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 utility model is described in further detail 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 W9Cr4V2.
