Connect；
3rd step, overlap, use cutting knife by the most die-cut for all rim charges of position, the plurality of hole, make to punch out in strip
Position, hole waste material forms an entirety with position, hole rim charge, and strip is formed the saw blade hole of a smooth another side sawtooth, phase
Sheet material between adjacent two saw blade holes forms required saw blade；
4th step, trimming, the coupling part at saw blade two ends with strip is cut off, automatic blanking forms finished product.
It is also preferred that the left be additionally provided with a concora crush step between described 3rd step and the 4th step, by strip through cutting tongue and overlap
After step, produced burr and bending flatten.
It is also preferred that the left described blanking die is multiple operation progressive die, the first step is to the 4th step and the manufacturing procedure of concora crush step
All on this multiple operation progressive die, the first step is carried out to the 4th step and concora crush step simultaneously.
It is also preferred that the left the described first step to the 4th step and concora crush procedure of processing is respectively arranged with independent mould, each independent mould
The upper die and lower die of tool are unified respectively to be arranged on the upper and lower pressure plare of forcing press, adds each individual die synchronous working in man-hour.
It is also preferred that the left empty step can be respectively equipped with between all procedure of processings.
Compared with prior art, the invention has the beneficial effects as follows: one, employing are cut tongue processing and realized half punching of position, multiple hole
Cut, it is to avoid the formation of particle, the rim charge of the most die-cut the porose position, make position, the hole waste material of porose position formed with position, hole rim charge
One overall cutting, overall waste material is not result in jumping the phenomenon of bits due to the effect of gravity；Two, the molding side of the present invention
Method production efficiency height, dimensional accuracy height, the good product quality produced and stay in grade, have for many dentations thin material Product processing
Great technological innovation meaning.

[detailed description of the invention]
Below in conjunction with the accompanying drawings and detailed description of the invention the invention will be further described:
As shown in Figures 1 to 4, the porous punching of a kind of gear piece of the present invention processes forming method without particle, produces
Saw blade be mainly used on the devices such as printer, copy and spray drawing machine, in order to eliminate electrostatic.This forming method includes walking as follows
Rapid:
The first step, punching, choose metal base strip 1 according to the requirement of the shape and size of product, make strip 1 through automatically
Feeder is sent in blanking die by the step pitch of regulation, and the both sides of strip 1 are rushed location hole 11 respectively；This hole, location 11 with
The pilot pin of subsequent step matches, and on strip 1 the same side, the distance in adjacent two holes 11, location is i.e. each step of autoloader
Step pitch, the pilot pin on subsequent step acts on jointly with the motor of autoloader, it is ensured that strip 1 be sent into precision
The precision die-cut with mould.
Second step, cuts tongue, is accurately positioned, the strip 1 after punching then to orientation by pilot pin
The multiple hole position 12 vertical with strip feeding direction carries out cutting tongue processing, and the through hole of protrusion of the tongue is cut in strip feeding direction in position, hole 12
One end is wedge angle, with strip 1 mutually forms certain angle or perpendicular shape after position, hole waste material 121 bending formed after cutting tongue,
And be connected on the other end of through hole, thus avoid the formation of particle.
3rd step, overlap, use cutting knife 13 by the most die-cut for all rim charges of position, the plurality of hole 12, make strip 1 upper punch
Position, the hole waste material 121 cut out and position, hole rim charge form an entirety, and overall waste material (shown in Fig. 3) is bigger, due to the work of gravity
With, will not jump on the surface of mould, it is to avoid jump the phenomenon of bits；The smooth another side in one side of described cutting knife 13 is zigzag,
The sawtooth of cutting knife 13 with the wedge angle of porose position mutually stagger, make in die-cut rear strip, to be formed with a smooth another side saw
The saw blade hole 14 of tooth, the toothed edge in this saw blade hole 14 is acted on jointly by toothed edge and all wedge angles cutting tongue apertures position 12 of cutting knife 13
Formed；In strip, the sheet material between adjacent two saw blade holes 14 forms required saw blade 15.
4th step, trimming, the coupling part at saw blade 15 two ends with strip 1 is cut off, automatic blanking forms finished product.
Wherein, between described 3rd step and the 4th step, it is additionally provided with a concora crush step, by strip through cutting tongue and overlap step
After rapid, produced burr and bending flatten.
It is also preferred that the left all procedure of processings of the present invention can be provided entirely in a secondary blanking die, this blanking die is many
Working procedure level progressive die, the manufacturing procedure of the first step to the 4th step and concora crush step all on this multiple operation progressive die, the first step to
Four steps and concora crush step are carried out simultaneously, it is ensured that the uniformity of all procedure of processings, improve production efficiency.
It addition, the present invention can also use, and to the 4th step and concora crush procedure of processing, the described first step is respectively arranged with independence
Mould on, the upper die and lower die of each individual die are unified respectively to be arranged on the upper and lower pressure plare of forcing press, it is achieved add man-hour
Each individual die works asynchronously, and such structure that arranges, while ensure that the uniformity of procedure of processing, is also convenient for each processing
The maintenance of the mould of step and replacing, reduce the purpose of die cost.
Further, a step sky step or multistep sky step between all procedure of processings, can be respectively equipped with, in order to improve mould knot
The intensity of structure.
The announcement of book and teaching according to the above description, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula carries out suitable change and amendment.Therefore, the invention is not limited in detailed description of the invention disclosed and described above, to this
Some modifications and changes of invention should also be as falling in the scope of the claims of the present invention.Although additionally, this specification
In employ some specific terms, but these terms are merely for convenience of description, and the present invention does not constitute any restriction.
