Abstract

The utility model belongs to the field of a cutting tool, particularly to a separate milling cutter for processing all kinds of chamfered grooves, which comprises a cutter handle and a cutter head, wherein the cutter head is arranged at the end part of the cutter handle, the cutter head and the cutter handle are fixedly connected through a nut, fixed circumferentially through a key, and spaced axially through a step, knife edges are uniformly arranged at the periphery of the cutter head, and the included angle Alpha between the extended line of the top end of the knife edge and the cutter head surface is 18 degrees. The utility model has the advantages that the processing procedure is eliminated, time and labor are saved, usage is convenient and the source cost is saved.

Description

Split type milling cutter

Technical field

The utility model belongs to the machining field of tool, particularly a kind of split type milling cutter that is used to process various chamfering grooves.

Background technology

Chamfer machining is applicable to mould, mould bases chamfer machining, bed piece processing, and iron and steel processing, the sheet metal chamfering, machinery equipment chamferings etc. are widely used in industries such as iron and steel, steel construction, mould, metal processing, hardware manufacturing; Milling cutter has a variety of, general milling cutter is the integral type milling cutter, cutterhead and handle of a knife are that one processes, need very thick material to process, production cost is than higher, and when in the cutterhead use, being damaged, can't change, can only be that handle of a knife is more changed together, use cost is very big like this, and its manufacturing cost makes many enterprises hang back on the big basis more, and common milling cutter processing type groove also needs later on to carry out chamfer machining with the chamfering utensil, two procedures is numerous and diverse tediously long like this, wastes time and energy.

Summary of the invention

The utility model provides a kind of split type milling cutter at the high shortcoming of inconvenience of using of use manufacturing cost of above-mentioned technology.

Realize that scheme of the present utility model is as follows:

Split type milling cutter, it comprises handle of a knife and cutterhead, cutterhead is arranged on the end of handle of a knife, cutterhead and handle of a knife are fastenedly connected by nut, circumferentially fix by key, and be axially spacing by step, described cutterhead circumferentially evenly is provided with blade, the top blade extended line of this blade and the angle α of cutterhead card are 18 °, and handle of a knife and cutterhead are provided with keyway, and described key is arranged in this keyway.

Described blade has two blades, and these two blade axial symmetry.

Utilize the split type milling cutter of this utility model, it comprises handle of a knife and cutterhead, it comprises handle of a knife and cutterhead, cutterhead is arranged on the end of handle of a knife, cutterhead and handle of a knife are fastenedly connected by nut, circumferentially fix by key, axially spacing by step, described cutterhead circumferentially evenly is provided with blade, and the top blade extended line of this this blade and the angle α of cutterhead card are 18 °, because cutterhead and handle of a knife are split type, therefore the utility model has the advantages that cutterhead directly carries out chamfer machining in processing type groove process, omit a procedure, and when cutterhead is damaged, directly change cutterhead, easy to use, save resources costs.

Description of drawings

Fig. 1 is a split structural representation of the present utility model;

Fig. 2 is the A portion enlarged diagram of Fig. 1;

Among the figure, 1, handle of a knife, 2, cutterhead, 3, nut, 4, blade, 5, blade.

The specific embodiment

As shown in Figure 1 and Figure 2, the split type arc shaped groove milling cutter of the utility model, this milling cutter comprises handle of a knife 1 and cutterhead 2, cutterhead 2 is arranged on the end of handle of a knife 1, cutterhead 2 is fastenedly connected by nut 3 with handle of a knife 1, cutterhead 2 all is provided with keyway with handle of a knife 1, circumferentially fixes by key, and is axially spacing by step, cutterhead 2 circumferentially evenly is provided with blade 4, top blade 5 extended lines of this blade 4 and the angle α of cutterhead 2 cards are 18 °, and blade 4 has two blades 5, and these two blade 5 axial symmetry.

The utility model is that handle of a knife 1, cutterhead 2, nut 3 splits combine, and cutterhead 2 circumferentially evenly is provided with blade 4, and the top blade extended line of this blade 4 and the angle α of cutterhead 2 cards are 18 °.Therefore just carried out chamfer machining in processing type groove process, omitted a procedure, inconvenient and the high problem of cost are used in the milling cutter processing that has solved handle of a knife and cutterhead integral type.

Claims
