Main application and feature
1. Main application
Z94-100A nail making machine is mainly used for making round nails with
diameter (2.8-4.5mm), length (50-100mm). .With slightly refitting the wire
strengthening system and punching system of the machine, we can make
other specific steel nails, such as coil roofing nails, roofing nails, etc.
2. Feature
(1.) elegant appearance, Reasonable structure, Stable performance,
Security and reliability, Durability in use, Easy maintenance, High efficiency.
(2.) The main parts like all the shafts, cams and gears are made of quality
steels.
(3.) The feeding system is installed with control handles, which makes it
easier to feed wires or stop feeding wires at any time during machine running.
(4.) An friction device is assembled between crank shafts and flywheels to
provide protection when a machine break down or overload.
(5.) Full automation. Once launched, it can make nails continuously.
Main mechanism and regulation
1. wire strengthening system(picture2)
strengthening wire pedestal700, which have 8gears702,703,706,etc to adjust steel

4. wires, is fastened on the feeding wire shelf800 with screws .
Adjust gear702 by spinning screw701 to adjust the curving degree of crew
between up and down. Adjust gears706,703 by spinning screw705 to
adjust the curving degree of screw between left and right. Wire enters the
system through 707.
2. wire feeding system(picture3)
feeding wire pedestal800 is fastened in the form of the body100
with screw803.The one side of draw bar804 is linked with feeding wire
eccentric disc202, the other side of which is linked with transmission
arm805.And the other side of transmission arm is connected to clamping
slide801.When crank shaft spinning, feeding wire eccentric disc202 spins
with it. Meanwhile it drives draw bar804 to move back and forth, which
impels transmission arm805 to move around 806,and brings along
clamping slide801 sliding back and forth to feed wires.
Pulling feeding control handle802 can control feeding and make it stop
anytime during running.
Adjusting the angle of feeding eccentric disc202 can change the feeding
time.
Adjusting bar201, resting on feeding eccentric disc, can get different wire
feeding length.
Adjust the length of silde804 can get different places, where feeding wire
slide moves.
With adjusting the position of slide807, the feeding wire shears mark can
be regulated to nail cap or nail head, which realizes no shears mark on the
nail body.
3. mould-die and clamping system(picture4)
Nail mould seat900 is installed on the supporting surface of mould table.
Gear909, located on transmission arm905 contacted cam312. With the
effect of spring908, gear909 keeps a certain pressure with cam312.The
turning of right axis makes cam reverse. Because of the effect of cam

5. surface, transmission arm905 moves around hinge pin. Drag hook907
drives left nail mould moving back and forth through tip903 to realize
clamp and wire-loosening.
Spinning screw904 can adjust the clamp level of wire.
Spinning screw910 can adjust die hole position around.
Spinning screw901 can adjust die hole up and down positions.
4. punching system（picture5）
Slide504 is located in guidetrack groove. The one side of connecting rod is
linked with crank shaft213, the other side of which is connected with slide
504. The spinning of crank shaft makes 501 drive slide504 moving back
and forth in main guidetrack groove to achieve punching.
Loosening pressing plate and spinning screw nut506 can adjust the length
that puncher pin507 stretches out of the slide. Consequently the thickness
of nail cap can be adjusted. When the machine stops and flywheel can not
move, Loosening screw nut506 with much strength can make it work
again.
Wedge502 slightly plugs into the chute of slide504 with its own gravity and
makes the gap between screw503 and wedge502 is 0.5-1mm (making
sure the machine works)
5. cutting system
Cutting system lies in the inside of left and right side shafts, symmetrical.
The one side of connecting rod604 is linked with side cam shaft, the other
side of which is connected with scissors slider603. Because of the effect of
partiality, the spinning of side cam shaft drives scissors slider moves
around to achieve cutting nails.
Spinning screw605 can adjust the longitudinal position of scissors
seat608, consequently adjust that of the pointingknife.
Spinning screw606 can adjust up and down position of modulation 607,
Consequently adjust the that of the pointingknife.

6. Spinning screw602 can adjust wedge609 to achieve the regulation of the
length pointingknife601.
6. Wire reel system
Wire reel system lies in the form of the machine, base seat312 is fixed by
screw315. Payoff reel313 is used for storing wire. The stanchion314 and free
foot315 is used for fixing wires. When wiring is needed, you can take out
plug317, then wire coil hangs.
Lubrication system(picture8)
1. The machine uses 3# or 4# calcium base oil.
2. When first use it, you should lubricate rubbing surfaces for removing
remaining dirt in 15 days.
3. You can use it again after lubrication of every rubbing surface when it is
out of use for a long time.
4. The machine should be lubricated regularly.

Maintaince:
1)Don’t adjust the length when the machine is operating.
2)Keep the machine clean,wash the dies regularly,don’t use rusty steel to
make nails.
3)Don’t feed the wire until the machine is started up steadily,stop feeding first
when turn off the machine.
4)Keep the knife sharp.
5)Should notice the unusual noise when the machine is operating.
6)Disconnect the power before implement the maintaince.
7)Inject oil to lubricate the machine frequently and make each part works well.
