High Speed Automatic Wire Drawing Machine For Wire 0 . 9 - 5 . 5mm
Instruction of wire drawing machine
1. Drive System
The way of transmission for wire drawing machine is by: Variable
frequency motor + Narrow v-belt + Decelerator with hardness gear
surface + Narrow v-belt to drive the block.
2. Block
Block is accurately founded by cast steel, re-tempering treatment
after the rough processing, the work surface of block is welded by
wear-resisting piano wire then sprayed with carbide tungsten, then
finish machined by a grinding machine. The block working surface
rigidity is over HRC60. The inside surface of block is sprayed with
Aluminum.
Block inside adopts narrow gap type water cooling while block
outside adopt concentrate air cooling. All blocks are fixed with
leaning rollers.
3. Die box
All are normal die boxes(die dimension should be offered by
client). Die box is cooled directly by water.
Tuning roller is driven by cylinder. Die box can be adjusted up to
down, front to back, left to right agility and can be fixed. The
screw in top and nut for die box are both made of tin bronze. Hard
alloy made direction guiding die is fixed at die box inlet.
4. Gearbox
The chief bearings for gearbox with hard gear surface adopt
products from Japanese NSK. All gearboxes are filled with VG220
compound gear oil before leaving factory.
5. Safety cover
On the top of each block there is a safety cover, which needs to
close before the equipment start up. If the cover is open, the
equipment can only run in slow speed. The safety cover has covered
the total front of operation side and have daylight lamp inside for
illuming use. Safety cover is controlled by spring.
6. Lubricating
Electric driven grease pump is fixed, which can automatically fill
oil into the chief shaft bearing of block.
7. Take-up
The coiler take-up adopts frequency conversion motor drive, to
achieve no-parking taking up. There are two rows of slide rail on
the bottom of bearing frame, to easy to replace the frame. (The
size of bearing frame is provided by the user).
