Abstract

The utility model relates to a disc milling tool for thickening and flat-mounted staggered teeth of an integral blisk flow channel, which belongs to the technical field of cutting tools. A plurality of L-shaped flutes are evenly distributed on the outer circumference of the cutter body, and a flute is processed on the side of the short flute of each L-shaped flute, and each adjacent two flutes are along the axis of the cutter body. Arranged in a staggered direction, a slider groove is processed on the bottom surface of each groove, a slider is arranged in each slider groove, a blade is arranged in each groove, and each blade is detachably and fixedly connected with the slider , each slider groove is provided with a slider, and there is a gap between each slider groove and the slider in the axial direction, and a tension screw is inserted into the through hole 2 of each slider groove to tighten The screw is tightly connected with the threaded hole 1 of the slider, and a threaded hole 2 is processed on the side wall of the groove perpendicular to the axial direction of each knife groove, and a set screw is screwed in each threaded hole 2, and each Two setscrews axially lean against the corresponding blades. The invention is used for the milling process of the whole blisk.

Description

technical field [0001] The invention relates to a disc milling tool, which belongs to the technical field of cutting tools. Background technique [0002] As an important core structural component of an aero-engine, blisks have complex structures, large blade twists, and poor flow channel opening. Most of the blanks are made of difficult-to-machine materials such as titanium alloys, which brings great difficulty to the manufacture of blisks. The material removal rate is about 60% when the blisk is roughed, so the performance of the roughing tool has a significant impact on the machining efficiency of the blisk. The traditional overall blisk slotting rough machining process mainly uses a ball-end milling cutter to cut the groove shape or use a slotting tool for plunge milling. Large, the tool is easy to break, and the tool has to be replaced, which not only affects the processing efficiency of the blisk but also increases the manufacturing cost. Using a disc milling cutter to...
