Description

A form drilling and milling cutter

technical field

The utility model relates to the technology in the field of cutting tools, in particular to a forming drilling and milling cutter.

Background technique

A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. Since the vast majority of cutting tools are machine-used and basically used to cut metal materials, the term "knife" is generally understood as a metal cutting tool. However, with the development of material science, various materials have been widely used in the production and processing of products, such as: engineering plastics and carbon fiber composite materials. The tools can be divided into several types according to the form of the workpiece processing surface: tools for processing various outer surfaces, hole processing tools, thread processing tools, gear processing tools and cutting tools.

In the prior art, the milling cutter and the drill bit are two independent cutters. When drilling and milling are required, the cutters need to be replaced back and forth, which brings inconvenience to use. Although there have been drilling and milling cutters at present, which can both drill and mill, however, the current drilling and milling cutters generally can only perform shallow milling, are difficult to achieve deep milling, and are still inconvenient to use.

Contents of the invention

In view of this, the utility model aims at the deficiencies of the prior art, and its main purpose is to provide a form drilling and milling cutter, which can perform drilling, and can also perform shallow and deep milling at the same time.

In order to achieve the above object, the utility model adopts the following technical solutions:

A forming drill and milling cutter, comprising a drill processing rod, a milling processing rod and a handle rod which are sequentially integrally formed and connected; the drill processing rod has a spiral groove and a helical surface, and the spiral groove and the helical surface are formed by the drill processing rod. The front end of the drill bit extends helically to the rear end along the same direction, and both sides of the helical surface are provided with helical blades, and the front end of the drill bit machining rod is provided with a plurality of oblique blades, which are respectively connected with the helical groove and the The ends of the two helical blades are connected; a plurality of linear blades for deep milling protrude from the peripheral side of the milling rod.

Preferably, the outer diameter of the drill shank is the same as the outer diameter of the tool handle shank, and the outer diameter of the milling shank is larger than the outer diameter of the drill bit machining shank and the outer diameter of the tool shank.

Preferably, the length of the drill rod is greater than the length of the milling rod.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

The workpiece can be drilled by cooperating with inclined blade, spiral groove, helicoid and spiral blade, and the chip removal is smooth, and the chip cutting efficiency is improved. The workpiece can be shallowly milled by using the spiral blade alone, and the workpiece can be milled by using the straight edge. Deep milling brings more convenience to use.

In order to illustrate the structural features and functions of the utility model more clearly, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
