Compared with the traditional thread machining method, the thread milling method has the advantages of high machining efficiency, simple and convenient working steps, high milling precision and the like. Chinese patent CN201920043781.0 discloses a thread milling cutter, which utilizes independent blades to mill inner holes of thin-walled workpieces, the cutter head of the thread milling cutter is designed with equal diameter, the milling pressure and resistance are large, the cutting edge is easy to damage, meanwhile, the thread milling cutter is a three-tooth thread milling cutter, the load of the cutting edge is large, the thread milling cutter is easy to damage, when the cutter is broken and the cutter is short or the service life of the cutter is finished, the machine adjustment for replacing the independent blades is very tedious, and the work efficiency is indirectly reduced.
Disclosure of Invention
In view of this, the utility model provides a five sword rectangle thread milling cutter to solve above-mentioned problem.
A five-edge rectangular thread milling cutter comprises a cutter head part and a cutter handle part which is integrally formed with the cutter head part; the diameter of the tool bit part is gradually reduced from one end close to the tool handle part to one end far away from the tool handle part; five knife edge parts are arranged on the circumferential outer side wall of the knife head part in a protruding mode, threaded convex edges are arranged on the knife edge parts in a protruding mode, and the cross sections of the threaded convex edges are rectangular; the thread convex edges of the five knife edge parts are integrally in a spiral shape.
Further, the width of the thread convex edge is 0.5-1.0mm, preferably 0.8mm, and the spacing distance between two adjacent thread convex edges is 0.5-1.0mm, preferably 0.8mm.
Further, the included angle between the thread convex edge and the central axis of the cutter is 5-15 degrees, preferably 10 degrees,
further, a cutter groove is concavely arranged between the two adjacent cutter blade parts, and the cutter groove is spiral in the length direction.
Furthermore, the bottom of the knife groove is arc-shaped, and two ends of the knife groove respectively extend to two ends of the knife head part.
Furthermore, the whole handle part is cylindrical, and a chamfer is arranged at one end of the handle part, which is far away from the head part.
Further, the diameter of the cross-section of the tool shank portion is greater than the diameter of either cross-section of the tool head portion.
Compared with the prior art, the utility model provides a five-blade rectangular thread milling cutter can carry out the turning to the hole of work piece simultaneously with five cutting edge portions, reduces the work load of each cutting edge portion, very big promotion the life of work efficiency and cutter. The diameter of the cutter head part is gradually reduced from one end close to the cutter handle part to one end far away from the cutter handle part, so that the thread can be milled gradually, milling pressure or resistance is reduced, the structural stability is high, and the accuracy of thread teeth can be improved.
Drawings
Fig. 1 is the structure schematic diagram of the five-blade rectangular thread milling cutter provided by the utility model.
Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1, it is a schematic structural diagram of a five-blade rectangular thread milling cutter provided by the present invention. The five-edge rectangular thread milling cutter comprises a cutter head part 10 and a cutter handle part 20 which is integrally formed with the cutter head part 10. Five blade parts 11 are protrudingly arranged on the circumferential outer side wall of the cutter head part 10, and a cutter groove 12 is concavely arranged between two adjacent blade parts 11.
The blade parts 11 are provided with thread convex blades 13 in a protruding way, and the thread convex blades 13 of the five blade parts 11 are in a spiral shape integrally.
The cutter groove 12 is formed spirally in the longitudinal direction, so that the blade part 11 is also formed spirally in the longitudinal direction.
The diameter of the tool head portion 10 decreases from the end near the tool shank portion 20 to the end away from the tool shank portion 20.
The width of the thread ridge 13 is 0.5-1.0mm, preferably 0.8mm, and the cross-section of the thread ridge 13 is rectangular in shape. The thread nose 13 is inclined at an angle of 5-15, preferably 10, to the radial direction of the head 10; the distance between two adjacent thread ridges 13 is 0.5-1.0mm, preferably 0.8mm. The bottom of the cutter groove 12 is arc-shaped, two ends of the cutter groove 12 are respectively located at two ends of the cutter head portion 10, and the spiral structure enables chip removal to be smooth, so that cutting fluid can be enabled to wash each thread convex edge 13.
The handle portion 20 is cylindrical, and a chamfer is provided at one end of the handle portion 20 away from the tool head portion 10. The cross-sectional diameter of the shank portion 20 is greater than the diameter of either cross-section of the head portion 10.
Compared with the prior art, the utility model provides a five-blade rectangular thread milling cutter can carry out the turning to the hole of work piece simultaneously with five cutting edge portions 11, reduces each cutting edge portion 11's work load, very big promotion the life of work efficiency and cutter. The diameter of the tool bit 10 is gradually reduced from the end close to the tool shank portion 20 to the end far away from the tool shank portion 20, so that the thread can be milled gradually, milling pressure or resistance is reduced, the structural stability is high, and the accuracy of the thread teeth can be improved.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
