Description
Technical field
The utility model is related to a kind of cutter more particularly to a kind of forming cutters.
Background technology
It is higher and higher to the quality requirement of product with the further raising of science and technology, substantially to a process
Manufacture requirement, criterion is one of molding, should ensure the quality of product, while angular cannot generate again.Cause to process non-
Often difficult, of high cost, precision is relatively difficult to guarantee.
Technique is to take multiple working procedure composition molding at present, is processed using molding cutter, but this cutter is manufacturing
In the process, there are reducing, the anterior angle at ladder is bigger than head anterior angle, causes position intensity at ladder low, easy tipping, so as to make
Into cutter breaking (anterior angle at the ladder of molding cutter is crescent at present), this allows designing for manufacturing to have a bad headache；However before head
Angle again cannot be small, cutting resistance can be caused big because head anterior angle is small, easily cuts motionless, lathe load alarm, even more seriously
Lead to breaking, defective work piece.And current forming cutter iron filings at ladder are easily wound.
Utility model content
Technical problem to be solved in the utility model is：In view of the drawbacks of the prior art, providing one kind has longer make
With the forming cutter in service life, can not only reduce cutting resistance makes cutting more brisk, but also can enhance position intensity at ladder, so as to prolong
The service life of long forming cutter.
The utility model uses following technical scheme to solve above-mentioned technical problem：
A kind of forming cutter with long service life holds the shank of simultaneously passing power including being used for machine tool spindle clamp, with
And the head for workpieces processing；
The head includes the molding blade for being located at the drilling sword in front and being connected with drilling sword；
Ladder is formed between the drilling sword and molding blade, the anterior angle that the molding blade is located at ladder forms a wedge angle and puts down
Platform.
In order to optimize above-mentioned technical proposal, the technical measures that the utility model is taken further include：
Further, the head includes surrounding at least two chip spaces of head center axis and be used to form described
The back of the body of chip space entity part, the chip space form reaming at the ladder；
Further, the reaming extends along head axes to forming cutter rear, increases the axial angle of reaming；
Further, the depth of the reaming is 0.2-1,2cm；
Further, the chip space forms main cutting edge, the main cutting with intersection of the back of the body on head axes direction
Sword is equipped with the interior cold hole for connecting the head and shank；
Further, the drilling sword, ladder, molding blade are integrally formed；
Further, the head and the shank are integrally formed.
The utility model uses above technical scheme, compared with prior art, has the following technical effect that：
1) the utility model carries out the amendment of an anterior angle at ladder, and the anterior angle at ladder uses point of a knife platform, replaces
Original crescent anterior angle is changed, is contacted by two original cusps, becomes to be countless on a line from the point of view of projection now
Point contact is linked to be, and enhances the intensity at position at ladder.The utility model extends the service life of forming cutter.
2) the utility model carries out the amendment of an anterior angle at ladder, using point of a knife platform, before increasing at ladder
Angle so that the anterior angle on forming cutter head increases, reduces the cutting resistance of forming cutter.The utility model makes cutting lighter
Soon, stock-removing efficiency is improved.
3) chip space of the utility model is equipped with reaming at ladder, and increases the axial angle of reaming, makes iron filings continuous
Bits, are not susceptible to wind.The utility model is conducive to the discharge of forming cutter iron filings, improves stock-removing efficiency.

Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of forming cutter with long service life holds the shank 1 of simultaneously passing power including being used for machine tool spindle clamp,
And the head 2 for workpieces processing；Head 2 includes the molding for being located at the drilling sword 3 in front and being connected with drilling sword 3
Sword 4；It drills and ladder 5 is formed between sword 3 and molding blade 4, the anterior angle that molding blade 4 is located at ladder 5 forms a wedge angle platform 6.This
The anterior angle of molding blade has been carried out an amendment by utility model, and original crescent anterior angle is modified to present point of a knife platform,
Head includes surrounding at least two chip spaces 7 of head center axis and is used to form 7 entity part of chip space
The back of the body 8, chip space 7 forms reaming 9 at ladder 5；Reaming 9 extends along head axes to forming cutter rear, increases the axial direction of reaming 9
Angle；The depth of reaming 9 is 0.2-1,2cm.Chip space is the channel that the Integrated Chip generated in process is made smoothly to discharge, chip removal
Slot is equipped with reaming at ladder, and increases the axial angle of reaming, Integrated Chip can be made more easily to be discharged.
Chip space 7 forms main cutting edge 10 with intersection of the back of the body 8 on 2 axis direction of head, and main cutting edge 10, which is equipped with, to be connected
Logical head 2 and the interior cold hole 11 of handle 1 referring to Fig. 2, in a kind of embodiment of the utility model, set that there are two interior cold holes 11 altogether.
In the forming cutter course of work, cutting fluid is sprayed from interior cold hole, plays the role of cooling, while iron filings can be washed away, reduces into
The cutting temperature of type knife extends the service life of forming cutter.
Drilling sword 3, ladder 5, molding blade 4 are integrally formed；Head 2 and shank 1 are integrally formed.
The working process of the utility model is as follows：Machine tool handle clamping shank 1, the rotation of band cutter and axial feed, simultaneously
Lathe have it is interior it is cold spray cutting fluid from interior cold hole 11, cut by main cutting edge 10, and cold cut is carried out to main cutting edge 10, into
The back of the body 8 of the knife of type plays a part of support, and iron filings are discharged from chip space 7, plays the role of a cutting.
By above-described embodiment it is found that a kind of forming cutter for having long service life provided by the utility model, at ladder
Anterior angle using point of a knife platform, replace original crescent anterior angle, contacted, become now from projection by two original cusps
From the point of view of be that countless point contacts on a line are linked to be, enhance the intensity at position at ladder, extend the service life of forming cutter；
Increase the anterior angle on head simultaneously, reduce the cutting resistance of forming cutter, improve the stock-removing efficiency of forming cutter.This practicality
It is novel that reaming is set at ladder, and increase the axial angle of reaming, iron filings is made to be easier to be discharged.
