Description
[technical field]
The present invention relates to the technical fields of pipe cutting machine, and in particular to a kind of cutter of non-sawdust lastic pipe cutting.
[background technique]
In the pipe cutting machine for plastic pipe, mainly saw blade is used to cut to plastic pipe.When cutting,
Can not only there be sawdust, but also the end face cut can have flange, and with the extension of use time, saw blade can be because of abrasion
And there is the phenomenon that fracture suddenly, it is serious to cause production accident.
[summary of the invention]
To solve the above problems, the purpose of the present invention is to provide one kind will not generate sawdust, and the end face after cutting
Without flange, and the cutter of the nonabradable non-sawdust lastic pipe cutting of cutter.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of cutter of non-sawdust lastic pipe cutting, including
The cutter hub of strip, the front end of the cutter hub are provided with the top knife portion and side tool portion put the first edge on a knife or a pair of scissors, and the cutting edge in the top knife portion includes top
The depth in knife cut-in portion and top knife expanded support portion, the top knife cut-in portion is 2.3~2.7mm, and the depth in the top knife expanded support portion is 9
~10mm is in 45 ° of angles between the side tool portion and top knife portion, and the cutting edge in side tool portion includes side tool cut-in portion and side tool expanded support
Portion, the depth of the side tool cut-in portion are 1.8~2.2mm, and the depth in side tool expanded support portion is 9.5~10.5mm.
The cutter of one of present invention non-sawdust lastic pipe cutting is further arranged to: the width of the top knife cut-in portion
For 2~2.3mm.
The cutter of one of present invention non-sawdust lastic pipe cutting is further arranged to: the width of the side tool cut-in portion
For 1.8~2.2mm.
The cutter of one of present invention non-sawdust lastic pipe cutting is further arranged to: the length of the top knife cut-in portion
For 12~18mm.
One of present invention non-sawdust lastic pipe cutting cutter be further arranged to: the cutter hub with a thickness of 4.5
~5.5mm.
The cutter of one of present invention non-sawdust lastic pipe cutting is further arranged to: the two sides in the top knife expanded support portion
Face angle degree is less than the two sides angle of top knife cut-in portion；The two sides angle in side tool expanded support portion is less than the two of side tool cut-in portion
Flank angle.
Compared with prior art, the invention has the following beneficial effects: above-mentioned non-sawdust lastic pipe cutting cutter,
Using accurate state modulator, the segment design side tool portion in top knife portion and tilting, and push up knife portion and side tool portion is respectively provided with
Angled different cut-in portion and expanded support portion, entire Pipe Cutting process is incremental, and there is no chips, and due to expanded support portion
Two sides angle is less than the two sides angle of cut-in portion, so there is no flange for the cut surface of tubing.Since cutter is not present
Sawtooth, and it is point contact that when cutter and tubing contact, which only just starts the moment of contact, is then face contact, so cutter
It is not easily damaged.

[specific embodiment]
It is further to a kind of cutter work of non-sawdust lastic pipe cutting of the present invention below by specific embodiment
Detailed description.
As shown in Figure 1, a kind of cutter of non-sawdust lastic pipe cutting, the cutter hub 1 including strip, the thickness of the cutter hub
A is 4.5~5.5mm.The front end of the cutter hub 1 is provided with the top knife portion 2 and side tool portion 3 put the first edge on a knife or a pair of scissors, as shown in Fig. 2, the top knife
The cutting edge in portion 2 includes top knife cut-in portion 4 and top knife expanded support portion 5, and the depth b of the top knife cut-in portion is 2.3~2.7mm, described
The width c for pushing up knife cut-in portion is 2~2.3mm.The length d of the top knife cut-in portion is 12~18mm.The top knife expanded support portion
Depth e is 9~10mm, is in 45 ° of angles between the side tool portion 3 and top knife portion 2, as shown in figure 3, the cutting edge in side tool portion 3 includes
Side tool cut-in portion 6 and side tool expanded support portion 7, the depth f of the side tool cut-in portion are 1.8~2.2mm, the width of the side tool cut-in portion
Degree g is 1.8~2.2mm.The depth h in side tool expanded support portion is 9.5~10.5mm.The two sides face angle in the top knife expanded support portion 5
Degree is less than the two sides angle of top knife cut-in portion 4；The two sides angle in side tool expanded support portion 7 is less than the two of side tool cut-in portion 6
Flank angle.
The working principle of the invention is: entirely to the cutting process of plastic pipe, practical is the cutting of squash type, pushes up knife
The cut-in portion tip of the joint in portion 2 and side tool portion 3 initially enters tube body, and tube body is made to scratch a notch, then pushes up knife expanded support
Portion 5 and side tool expanded support portion 7 gradually squeeze into the notch, the expanded support in incision, until the tube body of plastic pipe is cut off, entire Pipe Cutting
Process is incremental, and there is no chips, and since the two sides angle in expanded support portion is less than the two sides angle of cut-in portion, institute
With the cut surface of tubing, there is no flange.Since sawtooth is not present in cutter, and when cutter and tubing contact, has only just started
The moment of contact is point contact, is then face contact, so cutter is not easily damaged.
The principles and effects of the invention, and the implementation that part uses only is illustrated in the above embodiments
Example, and is not intended to limit the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from wound of the present invention
