Description

Technical Field

[0001] The utility model relates to the technical field of cutters, in particular to a layered milling cutter. Background Art

[0002] Milling machines are commonly used equipment for cutting processing. Milling cutters are generally multi-tooth tools with the advantages of high processing efficiency and high processing precision.

[0003] However, when the existing milling tool is in use, the cutting edge of the carbide insert is always in contact with the processing surface, and the contacting part will be greatly worn over time, thereby shortening the milling life of the carbide insert. Therefore, a layered milling tool is proposed. Utility Model Content

[0004] The utility model aims to solve the problem that the milling cutter in the prior art has large wear and shortened service life, and proposes a layered milling cutter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A layered milling tool comprises a tool bar and four blades. The front end of the tool bar is provided with four installation stations, and the four blades are fixedly installed inside the four installation stations respectively; the four blades are all triangular pieces, and the three sides of the four blades are all arranged with raised arc edges.

[0007] Preferably, the insides of the four installation stations are all provided with installation holes, and the insides of the four blades are all connected to the installation stations through the cooperation of bolts and the installation holes.

[0008] Preferably, the bolt is a concave plum blossom-shaped bolt.

[0009] Preferably, the four blades are installed in layers and staggered in pairs, wherein the milling parts of two of the blades are tips, and the milling parts of the other two blades are arc-shaped edges.

[0010] Preferably, the knife rod adopts a two-section rod body, and the two rod bodies are arranged with different diameters.

[0011] Preferably, each of the blades can be used six times with a replaceable angle.

[0012] Compared with the prior art, the utility model provides a layered milling tool, which has the following beneficial effects:

[0013] The layered milling tool has four blades arranged at the front end of the tool rod. The four blades are all triangular-shaped pieces, and the three sides of the four blades are all arranged with raised arc edges. The four blades are installed in layers and staggered in pairs, wherein the milling parts of two blades are tips, and the milling parts of the other two blades are arc edges. Therefore, during the milling process, different positions of the blades will contact the processing surface, which can reduce the wear of the blades. At the same time, each blade can be used for six times with a changed angle, which greatly increases the service life of the blades and reduces the cost of using the processing tools.

[0014] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model adopts a layered milling tool structure to improve the utilization rate of the cutting edge of the carbide blade, increase the milling life of the blade, and reduce the cost of use.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] Reference Figure 1-2A layered milling tool comprises a tool bar 1 and four blades 2. The tool bar 1 adopts a two-section rod body, and the two rod bodies are set with different diameters. Four installation stations 3 are arranged at the front end of the tool bar 1. The four blades 2 are fixedly installed inside the four installation stations 3 respectively. The four blades 2 all adopt triangular body sheets, and the three sides of the four blades 2 are set with raised arc edges. The four blades 2 are installed in layers and staggered in pairs, wherein the milling parts of two blades 2 are tips, and the milling parts of the other two blades 2 are arc edges. In the process of milling, different positions of different blades 2 will contact the processing surface, which can reduce the wear degree of the blade 2. At the same time, each blade 2 can be used for six times with a change of angle, which greatly improves the service life of the blade and reduces the cost of using the processing tool.

[0021] The inside of the four installation stations 3 are all provided with installation holes 4, and the inside of the four blades 2 are connected to the installation station 3 through the cooperation of bolts 5 and the installation holes 4. The bolts 5 are concave plum blossom-shaped bolts. By loosening the bolts 5, the four blades 2 can be installed at an angle for use. Since the three sides and three corners of each blade 2 can be used as milling parts, each blade 2 can be used for six times with angle changes, which greatly improves the service life of the blade.

[0022] In the utility model, when in use, the tool rod 1 is installed with the driving mechanism of the milling machine, and the tool rod 1 is driven to rotate by the driving mechanism, so that multiple blades 2 on the end face of the tool rod 1 are in contact with the processing surface at the same time. Since the milling parts of two of the blades 2 are pointed ends and the milling parts of the other two blades 2 are arc-shaped edges, different positions of different blades 2 will contact the processing surface during the milling process, which can reduce the degree of wear of the blades 2.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
