Abstract

The utility model discloses a double-edge milling cutter. A cutter head and a cutter handle are connected in a stamping manner, and a chip pocket is connected behind a chip groove of a chamfer cutter edge. The double-edge milling cutter overcomes the defects that the milling cutter is usually formed integrally, the machining difficulty is high, a hole edge head machining section is easy to stick and is even broken after completely extending into a hole in the prior art; according to the improved milling cutter, the raw material is saved; the manufacturing cost is lowered; the machining difficulty is reduced; and the service life of the milling cutter is prolonged.

Description

A kind of two blade milling cutters
Technical field
The utility model belongs to a kind of process tool, particularly a kind of two blade milling cutters.
Background technology
For Milling Process, typically use that fine finishining is carried out in drill bit reaming, milling cutter, chamfered cutting edge carries out chamfering, the waste manufacturing procedure; Milling cutter after a kind of improve was proposed afterwards, can process reaming, chamfer machining, but in order to pursue precision, the degree of depth of the processing sections of this milling cutter is all chosen fixed value, and milling cutter wants to reach reaming, chamfering is one-body molded, and size just, just the blade processing sections just all must be stretched into work piece, do the effect that also can play a location like this, improve machining accuracy.But the shortcoming of bringing like this is that when processing sections all goed deep into work piece, because chip removal is not smooth, cutter was stuck, or even fractures easily; And this milling cutter, usually cutter head, handle of a knife are one-body molded, and difficulty of processing is big, also wastes raw material.
The utility model content
Technical problem to be solved in the utility model provides a kind of milling cutter, can prevent the stuck even fracture of cutter, prolongs the service life of cutter.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of two blade milling cutters, comprise cutter head and handle of a knife, offer chip area on the described cutter head, punching press is connected described cutter head with handle of a knife, described cutter head front end is provided with reaming blade and chamfered cutting edge successively, is connected with chip pocket behind the chip area of described chamfered cutting edge.
Further, the bottom land of described chip pocket is arc.
Add man-hour, the processing sections of cutter is all stretched into work piece, the reaming blade is finished reaming processing, chamfered cutting edge is finished chamfer machining, is connected with chip pocket behind the chip area of chamfered cutting edge, can hold bits and handle.
It is a kind of novel mechanical interconnection technique that the German invents that described punching press connects, and is widely used in automobile, household electrical appliances and machine industry.Be used in the connection of metal sheet especially, the mechanism of this method of attachment is with a simple round punch connected piece to be compressed into recessed touching, and under further pressure effect, the material of this side of punch is pressed, material in the die is outwards flowed, can be connected and fixed.
Advantage: 1, cutter processing reaming, chamfering settle at one go.2, chip pocket can hold bits, and the cutter processing sections once all stretches into work piece, when reaching machining accuracy, can prevent that cutter is stuck.3, cutter head and handle of a knife segmental machining, the punching press connecting-type has reduced integrated difficulty of processing, has saved raw material, has saved cost, and punching press simultaneously connects the stability of effect not second to one-body molded.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Shown in Fig. 1, the utility model is a kind of two blade milling cutters, comprise cutter head 1 and handle of a knife 2, offer chip area on the described cutter head, 2 punching presses are connected described cutter head 1 with handle of a knife, described cutter head 1 front end is provided with reaming blade 4 and chamfered cutting edge 5 successively, is connected with chip pocket 3 behind the chip area of described chamfered cutting edge 5, and the bottom land of described chip pocket 3 is arc.
Add man-hour, in order to arrive one-shot forming, utilize the cutter processing sections fully, cutter is all stretched into work piece, reaming blade 4 is finished reaming processing, chamfered cutting edge 5 is finished chamfer machining, and the chip pocket 3 behind the chamfered cutting edge 5 can hold bits to be handled.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.

Claims (2)

1. blade milling cutter, comprise cutter head and handle of a knife, offer chip area on the described cutter head, it is characterized in that: punching press is connected described cutter head with handle of a knife, described cutter head front end is provided with reaming blade and chamfered cutting edge successively, is connected with chip pocket behind the chip area of described chamfered cutting edge.
2. two blade milling cutters as claimed in claim 1, it is characterized in that: the bottom land of described chip pocket is arc.
