Description
Technical Field
The invention relates to the field of metal cutting machining, in particular to a groove machining blade with stable positioning structure and long service life and a cutting tool with low size requirement.
Background
The up-and-down positioning of the slot processing blade is realized through the upper and lower positioning surfaces of the blade, and the upper and lower positioning surfaces of the blade are usually designed into paired convex surfaces or concave surfaces and are matched with a cutter body which is designed into paired and corresponding concave positioning surfaces or convex positioning surfaces to process various slot types. Fig. 1 shows a cutter structure in which a blade is a concave positioning surface and a cutter body is a convex surface in the prior art. The blade is simple to manufacture and convenient to use; meanwhile, the effective contact area of the blade positioning surface is increased by the contact positioning mode of the convex surface and the concave surface, the load bearing capacity of the blade on the side surface and the end surface is enhanced, the impact resistance and the collapse resistance of the blade are improved, and the service life of the groove machining blade is ensured.
While slot-forming inserts have many advantages in terms of the use of either a pair of male or a pair of female face-locating features, problems exist. Generally, a grooving insert is a hard alloy insert, which is often deformed during sintering, the upper and lower positioning surfaces of the grooving insert are difficult to completely contact when the grooving insert is assembled on a cutter body, especially, the grooving insert is deformed seriously during the cutting process of a cutting insert with a small cutting width, and the upper and lower positioning surfaces of the grooving insert and the cutter body may contact with each other at the deformed protruding part of the grooving insert. When the protruding part is in contact with the middle position of the blade, the blade loses the positioning effect in the side direction, and when the blade is laterally cut, the blade is rapidly worn or chipped due to unstable clamping; when the protruding part is in contact with the edge of the blade, the edge load of the upper and lower positioning surfaces of the blade is overlarge, the wall thickness between the upper and lower positioning surfaces and the side surface of the blade is too small, the shear stress of the upper and lower positioning surfaces of the blade towards the side surface is overlarge, and the upper and lower positioning surfaces of the blade are easily collapsed towards the side surface. When the blade is seriously deformed, even if the protruding parts of the upper and lower positioning surfaces of the blade have larger clamping force, the blade is unstably clamped, the blade is easily broken during cutting, and when the blade is applied to the processing of a rotary cutter, the blade can be separated from the cutter body and centrifugally flies out due to cutting vibration, so that the life safety of an operator is threatened.
