Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a chipping-resistant hard alloy single-edge milling cutter. Background Art

[0002] The single-edge milling cutter has a cylindrical shape. The outer wall of the single-edge milling cutter is provided with a spiral blade, and the bottom has a cutting blade. The workpiece is cut by rotating the single-edge milling cutter. The waste chips generated during the cutting process are discharged through the spiral chip groove opened on the outer wall of the single-edge milling cutter.

[0003] When a single-edge milling cutter is cutting, there will be great friction between it and the workpiece, which will generate a lot of heat. When the heat accumulates on the surface of the blade, it will cause the blade to deform, soften and break, resulting in chipping of the single-edge milling cutter. Therefore, water is currently sprayed on the outer wall of the single-edge milling cutter to cool the single-edge milling cutter. However, the water can only contact the outer wall of the single-edge milling cutter, and the contact time is short. The single-edge milling cutter itself has a certain thickness, which makes it impossible for the inside of the single-edge milling cutter to cool down quickly, resulting in a temperature difference between the inside and outside of the single-edge milling cutter, affecting the safe use of the single-edge milling cutter. In view of the shortcomings of the existing technology, we propose an anti-chipping carbide single-edge milling cutter to solve the above problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a single-edge carbide milling cutter that is resistant to chipping. It solves the problem that when the single-edge milling cutter is cooled by spraying water, the inside of the single-edge milling cutter cannot be cooled quickly, resulting in a temperature difference between the inside and outside of the single-edge milling cutter, and the single-edge milling cutter still suffers from chipping, affecting the safe use of the single-edge milling cutter.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a single-edge carbide milling cutter with anti-chipping edge, comprising a shank, a transition rod, and a cutter head, wherein the outer wall of the cutter head is fixedly connected to a spiral blade, and a cooling mechanism is provided inside the transition rod and the cutter head, wherein the cooling mechanism comprises:

[0006] A first channel is opened inside the transition rod;

[0007] an inlet, which is provided on the outer wall of the transition rod and communicates with the interior of the first channel;

[0008] The second channel is opened in the interior of the cutter head, and the second channel is connected with the interior of the first channel.

[0009] Preferably, a collecting groove is provided on the inner wall of one end of the cutter head away from the transition rod, and the collecting groove is communicated with the inner walls of the multiple groups of second channels.

[0010] Preferably, an outlet is provided at one end of the cutter head away from the transition rod, and the outlet is communicated with the interior of the collecting tank.

[0011] Preferably, a disconnecting groove is provided on the outer wall of one end of the cutter head close to the transition rod, and an inlet for cooling water to enter is provided on the outer wall of the disconnecting groove.

[0012] Preferably, a chip removal groove is provided on the outer wall of the cutter head, and the direction of the chip removal groove is the same as the direction of the spiral blade.

[0013] Preferably, the chip removal end of the chip removal groove is communicated with the disconnection groove.
