III . 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).
