Rotary milling and planing tool bit

Abstract

The invention relates to a rotary milling cutter head, which includes a tray and an ash discharger. An annular connecting ring is arranged on the tray, and a milling cutter and a chip removal cutter are arranged in an annular array on the connecting ring; the milling cutter includes a milling cutter There are a number of prismatic cutting protrusions in a linear array on the milling block, and buffer grooves are processed at the positions between the corresponding cutting protrusions on the milling block; the chip removal knife is installed in the drain hole that runs through the connecting ring , the chip removal knife includes several pieces of elastic blades, the elastic blades are fixed on the outer edge of the connecting ring corresponding to the discharge hole through the connecting seat, the axis of the elastic blade is inclined to the radial axis of the connecting ring, and a chip removal blade is provided between the chip removal knives Gap; the ash discharger includes ash discharge impeller, on which a circular array is provided with several arc-shaped impeller blades, a diversion cover is also provided on the ash discharge impeller, and a discharge port is arranged in the middle of the ash discharge cover. The middle part of the ash discharge impeller is rotatably connected with the middle part of the tray through a bearing, and an inertia block is also fixedly connected with the middle part of the ash discharge impeller.

Description

technical field [0001] The invention relates to a milling cutter used for chip removal on the surface of a steel plate, in particular to a rotary milling cutter head. Background technique [0002] Before the steel plate is finished, it is generally necessary to remove the oxide layer and initially polish the surface on a milling machine. There are generally two methods for this removal. One is to directly mill the surface of the steel plate with a milling cutter. This method has a better surface finish. , the secondary processing degree is relatively low, but the feeding speed of the milling cutter is relatively low, and the grinding rate is slow; the other is to grind the surface by grinding the tool. The debris is easy to cause secondary damage to the surface of the steel plate, and the surface flatness obtained after grinding is poor, and it takes multiple times of grinding to obtain the required surface, and the rate is also low.
