Product Description

Induction heating machine:

1. IGBT Power supply GZP-600KW/10KHZ-HB
Imported power components: the main components adopt 400A/1200V high-power IGBT to form parallel inverter circuit, which has excellent frequency automatic tracking ability.
Double closed loop and power loop control: double closed loop control of voltage and current; two modes of constant power control, with constant voltage or constant power operating function, that is, the end voltage of the inductor will not change with the external factors (such as line voltage, load impedance and so on) to ensure the stability of the load heating.
Parameter visualization: each set of equipment is equipped with a visual touch screen, which can input equipment parameters and accurately display the running state of the device, so it is easy to learn.
Higher intelligent digital control chip: the advanced control technologies such as the fixed angle phase locking and frequency automatic tracking of IGBT induction heating power supply are realized by high precision programmable device CPLD. The 16-bit machine is used instead of the original 8 bit machine to make the equipment running steady with high precision, and the temperature control can be accurately controlled and the quality consistency can be ensured. With the design of over frequency / low frequency inlock protection, it is more accurate and effective for short circuit and open circuit fault protection in wire heating inductor.
Digital fixed angle and frequency tracking: inverter circuit has the function of fixed angle and frequency tracking control. It can keep the inverter capacitive working angle unchanged when the load condition changes, and it has a very wide range of frequency application.
100% start-up: sweep frequency method to start, accurate phase locking frequency, small impact, can guarantee the success rate of 100% startup, power regulation range 10%~100%.
Sealing structure: the main cabinet equipped with main electronic components is designed with full sealed IP54 structure. It has good dust proof and waterproof effect. The internal cooling adopts a unique water cooler design. The tank circuit cabinet adopts a completely closed structure, which can effectively prevent the dust, iron pin and water from the internal short circuit and keep clean.

2. Capacitor cabinet GZP-600KW/10KHZ-HB
It is mainly for heating wire to a required temperature. The temperature range is 320-500°.

3.Water exchanger
Water-water exchanger adopts special corrugated structure design in plate heat exchanger, forming soft water into turbulence at low speed, strengthening the heat transfer. The system compact design is easily to unpack with a small area and high thermal efficiency.
The cooler has heat transfer ability but without a cooling ability and needs a circulation system to complete the heat exchange.

4. Operation table
SIEMENS medium-sized PLC smart. Man-machine interface is TPC1062K -10 - inch true color touch screen. Automatic control and management. Stable equipment performance, high running speed, maintenance-free. Technical process data EEPROM save, data invoke is applicable. Temperature probe has function of laser targeting and temperature displaying with small spot of light (only 2 mm), to facilitate targeting. The SIEMENS PROFINET communication mode is adopted, and it connects easily and reduces fault point with a fast control speed, can monitor motor parameters all the time.

Straight Line Drawing 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.

 

Capstan structure

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.

Drawing Dies

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.
 

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.)
