Description

Combined alloy milling cutter disc with replaceable cutter ring

Technical Field

The utility model relates to the technical field of milling cutter discs, in particular to a combined alloy milling cutter disc with replaceable cutter rings.

Background technique

The cutting tools commonly used in milling machines or processing machines are milling cutters. They remove the material of the processed object at a fixed feed rate in the machine. Milling cutters have concentrated shapes and many sizes, and the layers, as well as the helix angle and the number of cutting faces can also be selected. The milling cutter disc is one of the tools used to mill the plane of the workpiece.

The patent specification with announcement number CN213646025U discloses a milling cutter disc and a milling cutter disc assembly, including a cutter disc body, one end of which is used to connect to a machine tool, and the other end is a working end face, the working end face is provided with a plurality of tool grooves for fixing diamond-shaped blades, the plurality of tool grooves are arranged at intervals along the circumference of the cutter disc body, and include a bottom surface for fitting with the diamond surface of the diamond-shaped blade and at least two adjacent side surfaces for fitting with the side walls of the diamond-shaped blade. The two side surfaces of the tool groove are fitted with the two side walls forming the obtuse-angled blade on the diamond blade, which can limit and support the diamond blade. The other obtuse-angled blade on the diamond blade serves as a cutting edge and is exposed from the notch of the tool groove to the working end face. The exposed cutting edges in multiple tool grooves can be used for milling the plane, thereby realizing processing using the obtuse-angled edge of the diamond blade and improving the utilization rate of the diamond blade. At the same time, the angle between the plane formed by any point on the bottom surface of the tool groove and the central axis of the cutter disc body and the plane where the bottom surface is located is not zero. The diamond surface of the diamond blade is fitted with the bottom surface of the tool groove, so that the cutting edge of the diamond blade in the working state can have an acute back angle α0, thereby reducing the friction between the back surface of the diamond blade and the workpiece, reducing the wear of the back surface, and increasing the service life of the diamond blade.

However, in the implementation of relevant technologies, it was found that the above-designed fixture for a milling cutter has the following problems: one end of the cutter disc body of the device is used to connect to the machine tool, and the other end is a working end face, and the working end face is provided with a plurality of tool grooves for fixing diamond-shaped blades, which means that except for the blades, the rest of the structure of the entire device is an integrated structure, and in the subsequent milling process, the milling cutter disc and the blades in the tool grooves of the milling cutter disc are consumables, which will cause irreparable wear during use until they are scrapped or need to be replaced, and the device is an integrated structure, so when replacing it, the entire device needs to be replaced, which is a waste of materials. In view of this, a combined alloy milling cutter disc with replaceable knife ring is provided to overcome the above-mentioned defects.
