Description
Product IntroductionZHIXUAN ---- Servo Motor Direct Drive Wire Drawing Solution1. Equipment introduction
Servo Direct Drive Technology (SDT) wire drawing machine is the first one to achieve the connection between motor and block word-widely, which has merits in energy consumption, efficiency and maintenance, replacing parts of gearbox, belt and brake. It has a symmetrical and integrated design to save energy by 20%, space by 50% and maintenance by 40%. Such a machine has been applied widely in high, medium and low carbon wire, steel cord wire, bead wire, steel rope, welding wire, zinc coated wire, steel stranded wire, spring Wire and so on.

4.1 Drawing body
Servo direct drive motor- Connects with capstan directly
- No gearbox. No transmission belt. No mechanical break
- Comprehensive energy saving 10%-20%
Frame- Welding structure
- Not request for special foundation device
- Capstan position tilted, save more space and cost
- OTO pulley type for the first capstan
Electrical cabinet- The electrical cabinet and operation panel is integrated
- The control panel is on top of electrical cabinet
Water Cooling- Using coolant to cool motor and driver of motor, installing coolant tank, circulation pump, heat exchange, monitoring coolant temperature and level inside tank. In case needed, will alarm or stop machine
- Install cooling water pump to increase cooling water pressure, adopt invertor to control this pump, the flow of cooling water will follow the drawing speed
Capstan- Using slit type design when cooling water pass capstan, inner side of capstan is sprayed anticorrosive material, also avoid water scaled; the gap between temperature of capstan surface and temperature of inlet water<50ºC (the pressure of cooling water >0.1mpa)
- With water flow indication window, and outlet water temperature indication
- For capstan diameter more than 560mm (including 560mm capstan), install fan to cool capstan.
- Capstan is made by QT450 casting iron, with tungsten carbide spray on working surface, hardness >HRC60, thickness of layer ≥10 um, surface roughness ≤Ra0.8, capstan lifespan ≥3 year, within 3 year, if capstan have problem due to quality reason, will change free of charge
- The water bush is made of aluminium alloy, to enlarge the duration of water scaled
Die box- Welding structure, divide to two chamber, cooling chamber and lubricant chamber; independent cooling water supply, adopt over flow structure; sealing cover on cooling chamber; install lubricant drawing powder stirrer, install cover on lubricant chamber
- Die box can be rotated to left, right, up and down; install # type wire guide roller before die box
- Die fixing screw is made by copper alloy or stainless steel
- Optional wire anti-vibration device
- Outlet water flow indication window, and outlet water temperature indication
- First die box adopt forced lay on drawing powder device+ rotating die holder, to help drawing lubricating
Dancer arm
Adopt pneumatic cylinder to adjust tension of dancer, cylinder installed under protection plate: dancer arm can be dismantled fully Protection cover
- Full closed type (working with dust collection system together, if don't choice dust collection system, seller don't suggest full closed type); install safety lock and safety detecting (when machine running, the cover cannot open; in case open, line speed will decrease)
- With checking window and operation hole
- Each block has one cover, open by pneumatic spring
- Install LED lamp on top of cover, for operator, it is easy to check machine
4.2 Pay off unit
Double position overhead hydraulic rotating payoff stand
4.3 Descaler unit- Double V type, 6 wheels
- With straightening device at outlet
- With dust collector, trolley type
- Straightening device is hydraulic type
4.4 Sand belt unit - Automatic adjust position of belt
- Running will be synchronized with drawing machine
4.5 Coiler take up unit- Horizontal spooler for max 800mm reel
- Traverser unit is driven by independent motor, adopt gear tooth belt to do transmission, traverse return position can be adjusted, the reel is fixed by pneumatic cylinder
4.6 Internet of Things
