Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
Example 1:
with reference to fig. 1 and 2, the present embodiment provides a C-shaped blade, which includes a blade body 1 with a diamond-shaped cross section and an assembly through hole 2 formed in the center of the blade body 1, where the blade body 1 includes two sharp tool points 101 and two blunt tool points 102, the sharp tool points 101 and the blunt tool points 102 are rounded corners of R1.5 size, and the sharp tool points are working tool points. The side length of the blade body 1 is 16mm, and the thickness of the blade body 1 is 4.75 mm. The angle of the acute tip 101 is 80 °. The blade body 1 is made of hard alloy, and a suitable blade material is selected according to the material of a workpiece to be turned, for example, a blade made of YG8 or YG3X is selected for turning cast iron, a blade made of YT15 or YT30 is selected for turning carbon steel, and a blade made of YG8 or YT14 is selected for turning high-temperature alloy steel. The fitting through-hole 2 has a circular cross section. When the blade is applied to the indexable cutter bar, the position of the blade body can be fixed on the assembly through hole 2 by buckling the pressure head on the indexable cutter bar, mechanical vibration cannot occur, and meanwhile, 2 sharp tool points of the blade body can be respectively displaced and replaced for use, so that the tool changing time is reduced, and the service life is prolonged.
The utility model discloses set up the fillet of blade body into the circular arc of non-standard R1.5 size, no matter be CNC or ordinary car, the during operation only needs to make the blade body lean on the R1.5 circular arc that the work piece can accomplish the product drawing regulation once, and labour saving and time saving has improved work efficiency.
Example 2:
with reference to fig. 2 and 3, the embodiment provides a C-shaped blade, and the difference between the embodiment and the embodiment 1 is that 2 positioning holes 4 are formed in the blade body 1, 2 sharp tool points of the blade body can be respectively displaced and replaced for use, and positioning work during tool changing is completed through the two positioning holes 4 and the assembly through hole 2, so that difficulty in tool resetting is reduced. The chip groove 3 is formed in the upper portion of the blade body 1, when the blade works, chips above the blade are discharged out of the blade tip portion through the chip groove 3, the chips can flow out easily due to the chip groove 3, accumulated chip lumps are not prone to being generated during cutting, and the chips cannot be attached to a tool.
