The a line of complete rectangular cam, then go to cut another a line, tightly indent can not can be formed to the edge of rectangular cam, can also cause
Cutting speed is slack-off, causes unsightly and cutting efficiency is low.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of good appearance, it is efficient
A kind of progressive die trimming is without crossing point of contact cutter.
To achieve the above object, the utility model provides following technical solution：A kind of progressive die trimming is cut without point of contact is crossed
Knife, including cutter, the cutter include the first main cutter and the second main cutter, and the first main cutter and the second main cutter are in flat
Row setting, the end of the first main cutter is connected with the end of the second main cutter connect knife, the connection knife and the first master
Cutter vertical connection, the first main cutter and the one end for connecting knife connection are equipped with the first secondary cutter, the described first secondary cutter with
First main cutter is linearly arranged, and the second main cutter and the one end for connecting knife connection are equipped with the second secondary cutter, and described second
Secondary cutter is linearly arranged with the first main cutter, and the one end of the first main cutter far from connection knife is equipped with the first arc tips, institute
It states the one end of the second main cutter far from connection knife and is equipped with the second arc tips.
As preferred：End face arc-shaped setting of the described first secondary cutter towards the second secondary cutter.
As preferred：End face arc-shaped setting of the described second secondary cutter towards the first secondary cutter.
As preferred：One end of first main cutter towards the connection knife is equipped with the first arc interconnecting piece.
As preferred：One end of second main cutter towards the connection knife is equipped with the second arc interconnecting piece.
As preferred：The height of the upper padding plate is 15mm, and the height of clamping plate is 20mm, and the height of baffle plate is 15mm,
The height of upper de- plate is 22mm, and the height of lower template is 25mm, and the height of lower bolster is 20mm.
Use said program the utility model has the beneficial effects that：Adjacent to being cut into several on flitch
When rectangular cam, distance is equal with the connection width of knife between adjacent rectangular cam, the first main cutter, the second main cutter
And connection knife can be cut into three faces of rectangular cam, be set since the end of the first main cutter and the second main cutter is arc-shaped
It sets, will not can form indent to the edge of rectangular cam, it, can be to upper one when cutting next adjacent rectangular cam
4th face of rectangular cam is cut, when cutting the 4th face, the shape of the first secondary cutter and the second secondary cutter
If for arc, it is merely able to play the effect of rounding arc, other three faces will not be cut to, the edge of rectangular cam can be formed
Indent, cutting speed are accelerated, and good appearance, efficient effect have been reached.

Specific implementation mode
Referring to Fig.1 shown in Fig. 2, a kind of progressive die trimming that present case is implemented is described to cut without point of contact cutter, including cutter excessively
Knife includes the first main cutter 3 and the second main cutter 4, and the first main cutter 3 is set in parallel with the second main cutter 4, and described the
The end of one main cutter 3 is connected with the end of the second main cutter 4 and connect knife 5, and the connection knife 5 is vertical with the first main cutter 3
Connection, the first main cutter 3 are equipped with the first secondary cutter 6, the described first secondary cutter 6 and first with the one end for connecting the connection of knife 5
Main cutter 3 linearly be arranged, the second main cutter 4 and connect knife 5 connection one end equipped with second pair cutter 7, described second
Secondary cutter 7 and the first linearly setting of main cutter 3, the one end of the first main cutter 3 far from connection knife 5 are equipped with the first arc tips
8, the one end of the second main cutter 4 far from connection knife 5 is equipped with the second arc tips 9, and the described first secondary cutter 6 is cut towards the second pair
The arc-shaped setting in end face of knife 7, towards the arc-shaped setting in end face of the first secondary cutter 6, described first leads the described second secondary cutter 7
One end of cutter 3 towards connection knife 5 is equipped with the first arc interconnecting piece 10, and one end of the second main cutter 4 towards connection knife 5 is set
There is the second arc interconnecting piece 11.
When to being cut into several adjacent rectangular cam 2 on flitch 1, the spacing of adjacent rectangular cam 2
Equal from the connection width of knife 5, the first main cutter 3, the second main cutter 4 and connection knife 5 can be cut into rectangular cam 2
It three faces will not be to the edge of rectangular cam 2 meeting shape due to the arc-shaped setting in end of the first main cutter 3 and the second main cutter 4
