Ridge type turning tool blade

Abstract

The invention relates to a ridge type turning tool blade, and belongs to the field of machining. The blade comprises a tool body I and a tool nose combined groove II. The tool nose combined groove IIcomprises a chip division plate 1, a chip guide plate 2-1, a chip guide plate 2-2, a cutting edge 3, a butterfly-shaped combined groove 4 and a chip division baffle 5. The chip division plate 1 is ina ridge shape and is used for dividing cutting chips into two parts, and therefore the ridge portion is quite sharp. The chip guide plate 2-1 is an inclined plane and is used for guiding the cutting chips towards the two sides of the blade. The cutting edge 3 is of a blunt and round structure, and the strength of the cutting edge can be effectively improved. The chip cutoff groove 4 is in a butterfly shape and is used for chip cutoff. According to the chip division baffle 5, when the cutting chips are thick and wide, the cutting chips may not flow in the specified direction, and the chip division baffle 5 can be used for forcedly changing the flow direction of the cutting chips at this moment. According to the ridge type turning tool blade, the two functions of chip division and chip cutoff can be achieved, the cutting force and the cutting temperature generated in the cutting process can be effectively reduced, the aim of controlling the cutting chips can be achieved, the machining efficiency can be improved, and the ridge type turning tool blade is suitable for rough machining.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a roof-shaped turning blade, which has the functions of dividing and breaking chips of the blade. Background technique [0002] In rough machining, it is easy to produce strip-shaped chips entangled on the tool, which affects the heat dissipation performance of the tool. At the same time, the chips entangled on the tool will scratch the quality of the machined surface. If the chips are not controlled in time, when the chips are blocked, the heat on the chips will If it cannot be migrated, the heat generated by cutting will be transferred to the tool, and the heat generated by the friction between the chip and the workpiece will drastically reduce the durability of the tool. Therefore, it is necessary to design chip breakers and chip splitters to change tool performance. [0003] The chip breaker can effectively control the volume of chips, making it easier to handle, store a...
