[ detailed description ] embodiments

In order to make the technical problems, technical solutions and advantageous effects solved by the present application more clear and obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 3 to 6, the embodiment of the present application provides a T-shaped vertical ball-end-line groove forming graver, including a tool shank 1 for being fixed on a processing device to be processed in a rotating manner and a tool bit 2 arranged at one end of the tool shank 1, wherein a plurality of cutting portions 21 are arranged on the peripheral side of the tool bit 2, and a chip groove 22 is arranged between each cutting portion 21. Specifically, the cutting portions 21 are provided with 12 and uniformly distributed on the peripheral side of the tool bit 2.

The cutting portion 21 includes a groove edge 211 and two end face edges 212 respectively provided on both sides of the groove edge 211 and lower than the groove edge 211, a groove edge surface 213 inclined toward the center of the chip 2 extends in a direction away from the groove edge 211, and an end face edge surface 214 inclined toward the center of the chip 2 extends in a direction away from the end face edges 212.

During operation, handle of a knife 1 drives in the rotation process a plurality of cutting portions 21 of 2 week sides of tool bit are in turn processed the face of being cut, and the one shot forming line ditch, greatly reduced because the influence to the cutter life-span of high temperature that single-blade or twolip cutter repeated cutting formed in the short time, and then improve the life-span of cutter. Meanwhile, the T-shaped vertical ball head line groove forming graver is provided with a plurality of cutting parts, a plurality of cutting edges are provided, and the processing precision of the ball head line groove and the service life of the cutter can be further ensured by combining the structure of the T-shaped graver.

Accordingly, an arc-shaped transition edge 215 is provided between the groove edge 211 and the end surface edge 212. The coupling strength of the groove edge 211 and the end surface edge 212 is enhanced.

The strength of the edge is reduced when the inclination angle of the edge face is too large, and the edge is not sharp enough when the inclination angle is too small, so that the inclination angle a of the groove edge face 213 is 2 to 6 °, and the inclination angle b of the end face edge face 214 is 5 to 9 °. To achieve better cutting strength and sharpness.

Further, the chip discharge groove 22 has a notch 221 for blocking and rolling chips, one side of the notch 221 is connected to a chip guide surface 222 and is connected to the groove edge 211 and the end surface edge 212 through the chip guide surface 222, the other side of the notch 221 opposite to the notch is connected to a chip discharge inclined surface 223, and the chip discharge inclined surface 223 is connected to the adjacent cutting portion 21. When chips are formed on the cutting edge, the chips advance along the chip guide surface 222 until the notch 221 guides the chips formed in a coil shape, so that the chips are not easily scattered around to damage the workpiece, and heat can be better dissipated.

Furthermore, the ratio of the maximum radial dimensions of the shank 1 and the cutting head 2 is: 14:17 to 14: 21. Because the cutter in a cantilever state is easy to deform when the cutter is fed in the radial direction, the ratio can keep the difference between the radial dimensions of the cutter handle 1 and the cutter head 2 in a reasonable range, the deformation is reduced to the maximum extent, and the feeding precision is ensured.

More preferably, the material of the tool bit 2 is ultra-fine tungsten carbide. The hardness and wear resistance of the cutting tool can be enhanced by selecting the ultra-fine tungsten carbide as the material.
