Description

Be used for carbide milling cutter contour machining rolling device

Technical Field

The invention relates to the technical field of milling cutters, in particular to a forming and rolling device for a hard alloy milling cutter.

Background

A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine. The number of cutting inserts involved in cutting at any one time is an advantage, but too many, the power required is dependent on how many cutting edges are involved in cutting, and the position of the milling cutter relative to the workpiece plays an important role in chip formation, cutting edge loading and machining results. In order to ensure that a sufficiently high average chip thickness per tooth feed is used, the number of cutter teeth suitable for the process must be correctly determined. The pitch of the milling cutter is the distance between the active cutting edges. The milling cutter can be divided into 3 types, namely a dense-tooth milling cutter, a sparse-tooth milling cutter and a super-dense-tooth milling cutter according to the value. The milling is an essential step in the milling process, which is usually referred to as the mechanical process of deformation of the rolled piece between the rolls. In order to facilitate the analysis of the relationships between the various basic parameters of the rolling process, a so-called simple ideal rolling process is established, assuming that the metal to be rolled is a homogeneous continuous rigid-plastic body of rectangular cross section. The rollers are a pair of flat roller rigid bodies with equal diameter and speed, and have no external tension or thrust, so that the main parameters of the deformation zone are determined.

At present, in the process of processing the milling cutter, the milling cutter raw material is usually placed between two rollers, and the extrusion of the rollers forms knife lines on the milling cutter raw material, but the distance between the two rollers of the existing rolling device is difficult to adjust, and the milling cutter with the same size can only be processed, so that the limitation of the rolling device is increased, and the processing efficiency of the alloy milling cutter is reduced.
