Description

Wiper insert

Technical field

Cutting-tool engineering field is the utility model is related to, is specially a kind of wiper insert.

Background technology

With the update of China's machine tool industry, the rigidity and rotating speed of lathe are higher and higher, and market is to workpiece Surface requirements are higher and higher, especially Milling Process.Common typically no wiper edges of blade body on the market now, Shao Liangyou Linear pattern wiper edges, the knife angle of wedge of substantially such wiper insert is 90 °, and wiper edges are straight line mostly, and cutting edge band There is 10-25 ° of chamfered edge, easily produce built-up edge, the impact resistance of blade body is poor, and short life, the amount of feeding is small, cutting resistance Greatly, the workpiece surface finish of acquisition is poor.

Utility model content

The technical problems to be solved in the utility model is：Wiper insert is substantially that the knife angle of wedge is 90 ° at present, smoothing Sword is straight line mostly, and cutting edge carries 10-25 ° of chamfered edge, easily produces built-up edge, to solve the above problems, providing a kind of Wiper insert.

The purpose of this utility model is realized in the following manner：

Wiper insert, including blade body, the rake face of blade body are curved surface, and the rake face at each point of a knife is same On one circular conical surface, the cone angle of circular conical surface is β, 100 ° of 180 ° of ＜ β ＜, and the side of rake face and blade body is crossed to form smoothing Sword.

The circle that circular conical surface and the top surface of blade body are crossed to form is the inscribed circle of blade body.

The inscribed circle diameter of blade body is 9mm-20mm.

The fillet of 0.4mm-3.0mm is provided with the point of a knife of blade body.

Relative to the prior art, the blade body wiper edges of the utility model are arc-shapeds, blade body impact resistance Can be strong, the amount of feeding can increase, and improve stock-removing efficiency, extend the blade body service life, the workpiece surface finish processed is more It is good, the discharge of chip is also beneficial to, reduces the probability that built-up edge occurs.

Embodiment

As shown in Fig. 1-Fig. 7, wiper insert, including blade body 1, the rake face of blade body 1 is curved surface, each knife Rake face 3 at point is on same circular conical surface, as shown in figure 3, the cone angle of circular conical surface is β, 100 ° of 180 ° of ＜ β ＜, rake face Wiper edges 2 are crossed to form with the side of blade body 1.

The circle that circular conical surface and the top surface of blade body 1 are crossed to form is the inscribed circle of blade body 1.

The inscribed circle diameter of blade body 1 is 9mm-20mm.

The fillet of 0.4mm-3.0mm is provided with the point of a knife of blade body 1.

In Fig. 1-Fig. 3, using the quadrangle blade body that relief angle is 0 °, this structure applies also for the knife of triangle Piece body, as shown in fig. 4-5, the blade body of hexagon, as Figure 6-Figure 7.

Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as The scope of protection of the utility model.
