Description
Technical Field
The utility model relates to a processing blade technical field particularly, relates to a cutting blade.
Background
In the turning process, most of the metal cutting processes are metal cutting processes, the shape of the upper surface of the cutting blade has great influence on the cutting performance of the cutting blade, the cutting blade with the complicated cutting edge shape can effectively reduce the contact time between chips and the upper surface, and has excellent chip breaking and chip removal performance, but the cutting blade with a sharp groove shape has low strength and poor rigidity, can only be applied to processing occasions with small cutting force,
when the cutting force is large, the cutting blade is easy to vibrate, the vibration causes the cutting edge to be quickly worn so as to reduce the service life of the cutting blade, the abrasion is serious, the main cutting edge is easy to break, and the quality of the processed surface of a part is reduced; a cutting blade having a complicated cutting edge shape is difficult to manufacture, and is generally applicable only to rough cutting of a large-margin part due to the limitation of the edge shape, and is difficult to apply to finish cutting.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned technical problem among the correlation technique, the utility model provides a cutting blade can overcome the above-mentioned not enough of prior art.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows: the utility model provides a cutting blade, includes the handle of a knife of square body, the preceding tip of handle of a knife is equipped with the cutter body installation department, the rotatable square cutter body of installing of cutter body installation department, the upper surface and the lower surface of cutter body intersect and form the cutting edge, the tip of cutting edge is equipped with round chamfer, the cutter body with cutter body installation department contact surface is smooth plane.
Further, an included angle between the upper surface and the lower surface of the cutter body is an acute angle.
Furthermore, the middle part of the cutter body is provided with a mounting hole, and the cutter body mounting part is provided with a limiting shaft penetrating through the mounting hole.
Furthermore, the upper surface of the cutter body is provided with a chip groove, and the shape of the chip groove is arc-shaped.
Further, the tool shank and the tool body are both made of hard alloy materials.
The utility model has the advantages that: the cutting edge is formed by intersecting the upper surface and the lower surface of the cutter body, so that the cutting force is increased, and the cutter body is not easy to vibrate; the cutting edge is an acute angle and is provided with a round chamfer, so that the cutting precision is improved; the chip removal effect is enhanced through the arranged chip removal grooves, and the iron chips are prevented from being wound and accumulated; simple structure, convenient to use, the difficult fracture of main cutting edge.
