Capstan

(1)   Diameter:φ600mm

(2) Material is ZG45 steel casting blank body, after quenching and tempering treatment, HB250. Dig 5mm depth on the working surface of capstan, then melt the tungsten, cobalt carbide, overlay welding. Then rough lathing, precision lathing, grinding and polishing, surface roughness can reach to 0.08μm, hardening layer height 300mm, depth more than 3mm, HRC 58-62.

All the surface of capstan is processed by lathe, non-contact and operation surface’s roughness is 6.3μm, capstan inner wall sprays zinc, can effectively reduce the formation of cooling water scale.

Capstan spindle hole against axis beating up tolerance is ±0.03μm, capstan dynamic balance level is G6.3.

Capstan cooling

The main shaft of capstan is fixedly install an upper spiral water jacket, below is a water wheel. Capstan is mounted on the spindle, the lower part of water jacket and capstan inner wall form 10-15mm water storage. Circulation cooling water from the upper o water jacket to capstan inner wall, the water cabin is filled with cooling water will adequately cool the wounded steel wire. When capstan rotating, spiral groove will keep the cooling water to rise, then flow down along the capstan wall, discharge the water through the upper outlet, forming good circulation water cooling.

10

Machine frame

It is the foundation of the whole drawing machine units. It is welded by buttress plate, bent steel, section steel. All materials are designed safety enough to enhance the rigidity.

Frame processing:

The frame stands on the special leveling welding plate, weld the steel as base of the bottom plate. Then do the low temperature tempering and vibrating treatment to eliminate the welding stress.

Cold machining precision is the important factor to realize the high-speed drawing. Do the milling process for the bottom plane and connecting side of the frame. Then clamp the main hole and screw hole of the mounting surface.

Machining ended frame closures group in the painting shop, pain the anti-rust primer and do the scraping and deburring.

Lastly, paint second time topcoat painting according to customer’s color, wait for assembling.

Dies

(1)Die box is consisted of cooling water box and lubricate box

(2)Die size:Buyer provide

(3)Open water cooling

(4)The balance of turning roller is to use air cylinder, detection of angular displacement is to use non-contacting sensing type

(5) The drawing dies, besides the finished rolls, all rolls about 8 ° tilt to keep the wire reel maximum amount of plot lines and wire straight toward. Tuning rollers apply anti-pull the wire, to reduce mold drawing force.

Die box is welded structure, into two cavity. The guide roller is mounted into the side to ensure that steel wire can straight into the drawing die, die holder should be adjusted to wire tangent to enter the drawing rolls tuning roller installed at the entry end of the mold base tuning roll by a small cylinder put power, tuning the swing of the roller, so that the corresponding sensor output signal to fine-tune the speed of change. Tuning roller wire tension by adjusting the air pressure change, regulation range 0.15-0.6Mpa. The mold box is also equipped with a stirring device. Tuning roller side of the mold box, a gear reducer single-phase capacitance running motor through a sprocket, power passed to the stirring arm to stir the mold box, lubrication powder, without agglomeration affect lubrication.

13

Control type

(1)Siemens PLC S7-300 logic control system and AC conversion speed adjustable control system

(2)Main speed adjustable control is to use converter, high accuracy.

(3)Siemens 10’operation touch screen

(4) Sensors use the Schneider brand.

(5)Low-voltage electric use CHINT brand.

14

Other performance

(1)Equipped with double-preset length fixed meter

(2)Wire-broken emergency brake protective device

(3)Operating panel emergency brake, time is less than 5s

(4)Protective cover open, or length fixed non-reset, can’t start function

15

Vacuum

system

Cleaning dust, drawing powder, protect wire drawing machine

16

Safety shield

The shield uses whole closed structure which is welded section steel and steel plate. Façade designs hopper and transparent window with 10mm thickness polycarbonate plate. Use hollow rubber strips around the shield to protect and serve as a buffer.

Fulcrum design balance spring mechanism, through adjusting the balance spring pivot position, can achieve the shield is closed lightly.

Shield is provided with protective contact switch. It’s a device for realizing mechanical locking at run time. (When machine is running with shield opened, the unit immediately drop speed running or parking, recover normal after closing it. When it opens, the unit can only jog.)

17

Electrical parts

Electrical control steel central cabinet: sealed cabinet with the function of fan ventilation, filtration, moisture, dust prevention.

Master switch, PLC, variable frequency inverters are installed in the central cabinet. Each inverter microprocessor is in the standard of serial communication and in the protection of others, including relay contact element, light and 220 volt power outlet.

On the door of central cabinet: master switch operation handle, three-phase commutator, total voltmeter, total ammeter, ammeter for each AC motor, 220 volt power outlet and PC connected socket for sequence checking.

18

Panel layout

a. Touch screen can communicate with electric equipment in the central cabinet. Operation parameters and data can be input via touch screen, can be modified within the scope of authority.

During operating, various data is shown on the screen for people to monitor.

b. Operation button: can control the whole drawing line

‘S/W’(operation/preparation), ‘start’ , ‘stop’, ‘emergency stop’, light ‘on/off’

c. Operation control panel

Operation control panel is set on the front cabinet of capstan. Control components switches, buttons, valves are set on the panel.

‘start’, ’stop’, ‘quick stop’, ‘emergency stop’, ‘positive jog’, ‘front union working/back

union working’ ‘reverse jog’, ‘tensioner adjustment’, ‘barometer’,  ‘tension arm

adjustment’. These functional controllers can operate wire drawing line safely and

reliably.

19

Brake system

Design the disc brake at the output shaft of each motor. It consists of brake disc and hydraulic clamp pneumatic brake. The complete brake of the machine unit is generated by converter to motor energy consumption brake and pneumatic hydraulic brake. It can guarantee the reliable emergency braking in the high-speed operation of the unit.
