Description

Technical Field

[0001] The utility model relates to the technical field of plunge milling cutters, and more specifically, to an adjustable tungsten steel forming plunge milling cutter. Background Art

[0002] Adjustable tungsten steel profiled plunge cutter is a cutting tool used for metal processing. It is usually composed of an adjustable tool holder and a tungsten steel blade. The tool holder can be adjusted according to the processing needs so that the cutting angle and depth of the blade can adapt to different processing requirements. The tungsten steel blade is a high-hardness, wear-resistant tool material that can maintain the cutting performance and life of the tool under high-speed cutting conditions. It is often used for processing hard materials such as steel, copper, aluminum, etc.

[0003] Among them, it was found through searching that the utility model patent with patent application number CN202221008022.9 discloses a plunge milling cutter for cutting multiple surfaces of a product, including a shank portion, and the plunge milling cutter also includes: a first cutting portion, which is arranged at one end of the shank portion, the first cutting portion includes a first cutting edge, a second cutting edge and a third cutting edge, the first cutting edge is inclined relative to the axial direction of the shank portion to cut and form a chamfer, the second cutting edge is connected to the side of the first cutting edge away from the shank portion, and extends along the axial direction of the shank portion, and the third cutting edge is connected to the second cutting edge and is perpendicular to the axial direction of the shank portion;

[0004] When this structure is in use, the plunge milling cutter can process the chamfer of the product through the first cutting edge, and process different surfaces of the product through the second cutting edge and the third cutting edge. The surface and chamfer of the product can be processed by one tool. However, the dimensional accuracy requirements for the production of the plunge milling cutter are very high, especially the plunge cutter with a formed contour has a small inner diameter tolerance during the production process, and is also affected by processing runout, resulting in many deviations and a particularly high scrap rate, which leads to high production costs.

The specific structural arrangement of the component is as follows;

[0024] A central hole 6 is formed through the middle of the reinforcing tube 1, and the milling cutter body is arranged in the central hole 6;

[0025] A blade 4 is provided at one end of the milling head 3 away from the tool handle 2, a tool calibration position 5 is provided inside the center hole 6 and at one end of the blade 4, two first mounting holes 7 are provided on the top surface of the reinforcing cylinder 1, and a second mounting hole 8 is provided on the bottom surface of the reinforcing cylinder 1, the two first mounting holes 7 are respectively located on the outside of the tool handle 2 and the milling head 3, the second mounting hole 8 and the first mounting hole 7 located on the outside of the milling head 3 are on the same axial line, the two first mounting holes 7 are threadedly connected with first limiting bolts 9 extending to the outside of the tool handle 2 and the milling head 3 respectively, and the second mounting hole 8 is threadedly connected with a second limiting bolt 10 extending to the outside of the milling head 3;

[0026] The tool handle 2 and the milling head 3 are made of tungsten steel as a whole, and the blade 4 is a two-edged design. The cutting edge at the end of the blade 4 adopts a straight groove design, with a radial back angle of 5 degrees and an axial back angle of 8 degrees.

[0027] According to the above structure, when the milling cutter is used for processing, the wire cutting is first used to remove most of the excess, and the internal space of the blade 4 is hollowed out. The cutting edge of the head of the blade 4 adopts a straight groove design, with a radial back angle of 5 degrees and an axial back angle of 8 degrees, which not only ensures the cutting force of the blade 4, but also prevents the tool from vibrating and affecting the quality of the processed surface;
