Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, for the chip breaking turning tool disclosed by the present invention, the chip breaking turning tool comprises a cylindrical tool body 6 with a hexagonal cross section, the tool body 6 comprises two end surfaces 1 parallel to each other and six side surfaces 5, any two side surfaces 5 are connected to form a tool tip 8, an included angle between two adjacent side surfaces 5 is 80 degrees or 160 degrees, and the tool tip 8 is connected to any end surface 1 to form a tool tip 7; a chip groove 4 is arranged between the tool nose 7 and the end face 1, the chip groove 4 is arranged on the end face 1 and is arranged along the length direction of the end face 1, and a chip blocking block 2 which guides chips to a side face 5 parallel to the chip groove 4 is arranged on the end face 1. The turning blade cuts a workpiece 9 needing to be cut through the tool nose 7 in the cutting process, cutting chips are generated in the cutting process, and due to the action of cutting force, the cutting chips move towards the cutter body 6 and then enter the chip discharge grooves 4 formed in the tool nose 7, and then enter the impact chip blocking block 2 through the chip discharge grooves 4 under the guiding action of the chip discharge grooves 4, so that the cutting chips are curled and deformed again and further hardened and embrittled, and when the cutting chips collide with a part or a cutter, the cutting chips are broken easily, the broken chips are broken off from the outside of the cutter body 6, the situation that the part is damaged due to the fact that the cutting chips cannot be broken and the cutting chips are wound on the cutter is avoided, and the size control in the production process is more stable.

Referring to fig. 1 and 2, the space between the chip discharge groove 4 and the chip blocking block 2 is 13-15 degrees, which is more beneficial for cutting chips to fly out from the chip discharge groove 4 and the chip blocking block 2, and finally the cutting chips fly out from the side surface forming the cutter point 8, so that the influence on the cutter point 7 in cutting is avoided. The inner wall of the chip removal groove 4 is provided with the upward inclined surface 3, so that the accumulation of chips in the chip removal groove 4 is reduced, and the chip removal process is smoother.

Referring to fig. 1 and 2, two end surfaces 1 are provided with chip grooves 4 and chip blocking blocks 2, and one end surface 1 is provided with one chip groove 4 along the length direction of six side surfaces thereof. The chip grooves 4 on one end surface 1 are parallel to the side surfaces 5 forming the blade 8, and the chip grooves 4 on the other end surface 1 are parallel to the other side surfaces 5 forming the same blade 8. The chip removal directions of the chip removal grooves 4 on the two end surfaces 1 are different, so that in the chip removal process, chips can be removed from two sides of the blade 8, the phenomenon that chips are removed from one side only and chips are accumulated on one side of the blade 8 due to the fact that the chips are removed from the other side cannot be avoided, and the cutting effect is affected.

The implementation principle of the embodiment is as follows: the cutting chips generated in the cutting process continuously impact the chip blocking block 2 through the chip discharge groove 4, so that the cutting chips can be curled and deformed again and further hardened and embrittled, and when the cutting chips collide with a workpiece 9 or a cutter, the cutting chips are easily broken, the service life of the cutter is prolonged, the surface damage and damage of the workpiece 9 caused by unsmooth winding of the cutting chips are avoided, and the size control in the production process is more stable.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
