Description

Ultra-shallow parabolic groove type corrugated milling cutter

Technical Field

The utility model relates to a relevant technical field of cutter specifically is an ultra-shallow parabolic groove type corrugated milling cutter.

Background

A tool is a tool used for cutting machining in machine manufacturing, and is also called a cutting tool. Most knives are machine, but also hand-held. Since tools used in machine manufacturing are basically used for cutting metal materials, the term "tool" is generally understood to mean a metal cutting tool. The cutting tools for cutting wood are called woodworking tools. There is also a class of tools of particular application for geological exploration, well drilling, mine drilling, called mine tools, which are suitable for fine machining of gray iron ductile iron. 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 face milling, with a milling cutter that is about 30% larger than the cutting width and positioned close to the center of the workpiece, the chip thickness does not vary much. The thickness of the chip cut in and out is slightly thinner than the thickness of the chip cut in the center cutting.

The traditional corrugated milling cutter has the core thickness of 60 percent relative to the outer diameter of the core, the shank part of 70 percent close to the core thickness of the traditional corrugated milling cutter has poor rigidity, so the service life of the traditional corrugated milling cutter is low, in addition, the row cutting groove of the traditional corrugated milling cutter is a U-shaped groove, the row cutting performance of the traditional corrugated milling cutter is low, and aiming at the problem, the ultra-shallow parabolic groove type corrugated milling cutter is designed to solve the problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an ultra-shallow parabola cell type ripple milling cutter has solved the problem that proposes in the background art, satisfies the in-service use demand.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an ultra-shallow parabola flute type ripple milling cutter, includes the stalk portion, the one end of stalk portion is connected with the bed knife, milling cutter groove has been seted up to one side of stalk portion, the junction of bed knife and parabola flute type is the knife tip circular arc.

In a preferred embodiment of the present invention, the bed knife is fitted into one end of the shank and penetrates to the outside thereof.

As a preferred embodiment of the present invention, the milling flutes are parabolic troughs.

As a preferred embodiment of the present invention, the parabolic trough of the handle is provided with a milling cutter core at the inner position, and the core thickness of the milling cutter core accounts for 85% of the diameter of the handle.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses for traditional ripple milling cutter, the thick relative external diameter proportion of core is 85%, and the rigidity is superior to traditional ripple milling cutter, in addition, the utility model discloses use the parabola cell type, make its row cut the performance and promote 20%.

2. Specifically, when the ultra-shallow parabolic trough type corrugated milling cutter is used, a traditional U-shaped trough is changed into a parabolic trough, the joint of the parabolic trough and a bottom cutter is ground into a cutter tip circular arc, normal use can be achieved, and the milling cutter can greatly improve cutting performance and prolong service life.
