5.3 Main technical parameter and points:

(1) Inlet strength: ≦1300 MPa

(2) Max inlet dia: Ф6.5mm

(3) Min wire outlet dia: Ф2.5mm

(4) Max compression rate:97%

(5) Max drawing speed:10m/s Normal drawing speed:9m/s

(6) Water consumption and pressure:5m3/h water pressure≥0.25MPa

(7) Air consumption and pressure:1.0m3/h air pressure≥0.6MPa

(8) Motor:①Main motor:30KW*9 AC motor

② Wire take-up machine:22KW AC motor

(9) Drawing drum, Drum diameter Ф600mm,material:ZG45 steel,spray

tungsten carbide hard alloy powder on the working surface, thickness 1mm,height:60mm , Drum as a direct contact with the steel wire core components, its manufacturing technology also be especially fastidious. My company reel overall beautiful

sex and rigidity is higher; After tempering treatment after rough machining, in order

to improve the overall and mechanical properties of the drum; Drum face by

surfacing welding wear-resisting carbide processing, and then after grinding machinegrinding refined but become, within the drum surface processing has spiral u-shapeslot. Its cooling principle is through the drum and the relative rotary motion of the water jacket cooling water jacket of the lateral oblique rib to squeeze into the top, the inside of the drum helical will finish heat exchange cooling water down the u-

shaped groove to make it fast, within the drum surface processing with the

application of the spiral u-shaped slot technology, not only make the squeezing

effect of cooling water, and increased the reel internal heat exchange area, practiceproves that the application of this structure, drum heat exchange efficiency more than 30%, thus greatly improve the drum water cooling effect; Another drum wall caneffectively prevent the scale deposit on the inner wall of the drum, further to ensure the water cooling effect, and improve the service life of the drum.to ensure the quality of steel wire drawing. Drum surface finish Ra0.4 or higher, the surface hardness of about HRC60°, drum set satisfies the requirement of high-speed

drawing wire line height. Wear and tear up the slot free replacement within 5000h

(10) Rotational Die Box: ①Die rotation, when wire drawing,the die life

increased by 15%, and steel wire surface lubrication powder evenly, drawing speed

increased by 10%.

② Die box can be universal adjustment to ensure that the Angle of the steel wire drawing

which provides the high quality wire.

(11)Tuning roller:①Using Pneumatic anti-tension tuning , the tension is adjustable; guide pulley are sprayed with WC, useful life is more than two years. Sensor adopt angular displacement non-contact way, schneider sensor imported from Germany, make the process of template matching wider, mould can be automatically compensated after wear and tear, and it is difficult to break line.

② Using single control device which is originated in domestic, make sure that the swing when tuning roller is runing is not related to the direction of mould entering wire, wire entering angle is constant: 〈1〉make sure useful life of mould prolong more than 20%〈2〉make sure stable roundness when drawing;〈3〉make sure fine stable linearity when drawing

(12) Frame form:Wire drawing machine designed to form solid welding enclosure, the frame structure of the whole production process in strict accordance with the G level standard cold plate structure, ensure the machine of mesa verticality, smoothness and elevation of rigidity is very good, do not need special fixed; All rolls are installed, just face to beat no greater than 0.25 mm, using tuning roller tension

arm, between the two drum with sensors the match between two drum speed adjustment.

(13) Driving form:

① First, second block adopted Machine of decelerate of hard tooth surface gear transmission, 20CrMnTi gear material, surface hardness HRC62 °, surface finish Ra0.8, reducer adopts the reflux circulation lubrication of bearing, and design the lack of warning and automatic stop function. Configuration reducer can make customer drawing a little higher tensile strength of low carbon steel wire, the rest for two-stage transmission adopts powerful v-shaped moving belt.

② Each block with electromagnetic valve control efficient pneumatic brakes, brake force can be adjusted, ensure that emergency parking constantly silk wire drawing machine.

(14) Cooling system: ①the front panel of machine has ball valve to adjust water volume of reel cooling and mould cooling, and has pointer to consider water volume

② The whole cooling system make sure the temperature of reel surface≤60°C when the equipment running normally , not scald hand when touching

(15) Pneumatic system

① pneumatic spare parts: Taiwan AIRTIC pneumatic components products

② pneumatic system( incl . instrument, pipe line, electromagnetic valve, etc.)doesn’t leak

(16) Wire drawing machine bearing: adopt NSK bearings made in Japan.

(17) Control System:

① Configuration

a, frequency conversion :DARIN inverter made in China

b, PLC: imported from Japan mitsubishi series PLC

c, Sensor: French schneider imported photoelectric sensors

d, Relay and other low voltage electrical: imported French schneider

e, PanelvisaTouch screen: colour touch screen made in Taiwan

f, Into the line open, copper platoon, control of the specifications of the power supply, wires, choose reasonable

g, Cabinet put oneself in another& acute;s position: the standard of professional

manufacturer production cabinet put oneself in another& acute;s position.

② working way::straight line wire drawing machine control system adopt ac frequency conversion control, PLC logic control, full digital control, adopt imported high grade components, strong anti-interference ability, fast operation, is not only stable and reliable in operation, low energy consumption, and greatly improves the production efficiency, but also has multiple protection function, when shield equipment high speed open or have other fault occurs, the automatic stop device. After each machine is equipped with the points, the former linkage, linkage, the function such as start, stop, stop, work station of the main display, man-machine interface with the length of the preset speed preset display, fault query, equipment status, computer mold fitting, etc. the system generally using PLC programe control, frequency converter, touch screen to finish data exchange through communication, PLC can control reading, writing, turning on, turning off of frequency converter freely. PLC software can ensure programming and setting up automatic to the different drawing process, and it also can ensure operate smoothly; color screen man-machine interface can monitor the running conditions of equipment and fault display at anytime. Each process parameter can be set by the touch screen input. high precision, better accuracy, easy amendment, and can assure drawing process wider, realize jumping mould drawing easily. The whole system runs smoothly, low fault ratio, easy operation.
