Abstract

The utility model discloses an octagonal knife blade for processing the end face of a cylinder body, which comprises a knife body with an octagonal section. A cutting part is arranged at the rim position on the surface of the knife body, two sleeking angles are respectively arranged at the two edges of a knife point of the cutting part, and each sleeking angle is within 1 DEG and 50` to 2 DEG and 10`. With reasonable design and simple structure, the octagonal knife blade can obviously improve the processing precision of a work-piece, improve the product quality, effectively overcome the disadvantage of vibrating marks on the surface of the work-piece, and prolong the service life of a knife. Therefore, the octagonal knife blade can create good economic and social benefits for enterprises, and can completely adapt to rapid development of the mechanical processing and manufacturing industry.

Description

The octagon blade of processing cylinder body end face

Technical field

The utility model belongs to the Machining Technology field, relates in particular to a kind of octagon blade of processing the cylinder body end face.

Background technology

In the last few years, along with development of science and technology, machinery manufacturing industry was more and more higher to the requirement of machining accuracy.At present, the cylinder body end face is being added man-hour, the cutting tip of the blade that uses mainly is polycrystalline diamond (PCD) composite sheet or polycrystalline cubic boron nitride (PCBN) composite sheet, its composite sheet is that polycrystalline diamond (PCD) layer or polycrystalline cubic boron nitride (PCBN) form through the HTHP compacting with hard alloy layer, not default certain smoothing angle, two point of a knife places of cutting tip, the cylinder body end face that the blade of this structure is processed has chatter mark, processing quality and precision are lower, the manufacturing fast development of incompatibility machining.Therefore, the structure of this blade cut part is needed improvement badly.

The utility model content

The utility model provides a kind of octagon blade that can obviously improve the workpiece to be machined precision, promote the processing cylinder body end face of product quality in order to solve weak point of the prior art.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: the octagon blade of processing cylinder body end face, comprise that the cross section is octagonal cutter hub, cutter hub marginal surface place is provided with cutting tip, the point of a knife both sides of described cutting tip are respectively equipped with two smoothing angles, and the angle at smoothing angle is 2 ° ± 10 '.

The point of a knife of described cutting tip is an arc structure, and arc radius is 0.8mm, and nose angle is 139 °.

The summit at described two smoothing angles is 1.8 ± 0.1mm to the distance of point of a knife.

Adopt said structure, the point of a knife both sides of cutting tip are provided with two smoothing angles respectively, having solved shake surface of the work due to the cutter of original blade has the defective of chatter mark, and qualities such as the fineness in cutting face and suface processing quality also greatly promote; The arc structure of point of a knife setting helps to improve the service life of blade.The utility model is reasonable in design, simple in structure, can obviously improve the machining accuracy of workpiece, promote the better quality of product, having solved surface of the work effectively has the defective of chatter mark, and can prolong service life of cutter, for enterprise creates good economic benefit and social benefit, fully adapt to the fast development of mechanical processing manufacturing industry.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is the enlarged drawing at I place in the middle of Fig. 2.

The specific embodiment

As Fig. 1～shown in Figure 3, the octagon blade of processing cylinder body end face of the present utility model, comprise that the cross section is octagonal cutter hub 1, the surface of the cutter hub 1 wherein edge on one side is provided with cutting tip, form cutting tips 2 and point of a knife 3, cutting tip comprises polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PCBN) material layer 4 and hard alloy layer 5, polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PCBN) material layer 4 and hard alloy layer 5 are compressed to one, and hard alloy layer 5 solderings are on cutter hub 1.Point of a knife 2 and point of a knife 3 both sides are respectively equipped with smoothing angle α and β, α=β=2 ° ± 10 '.The point of a knife of cutting tip is an arc structure, arc radius r=0.8mm, nose angle γ=139 °.The summit of smoothing angle α and β to point of a knife 2 or point of a knife 3 apart from d=1.8 ± 0.1mm.

Two smoothing angle α and β, having solved shake surface of the work due to the cutter of original blade effectively has the defective of chatter mark, and qualities such as the fineness in cutting face and suface processing quality also greatly promote; The service life that the arc structure that point of a knife 2 and point of a knife 3 are provided with helps to improve blade.

Claims
