die polishing machine

die polishing machine for wire drawing machine 

It is mainly used in wire drawing machine dies

For flux cored wire drawing machine,copper coating machine dies

A.  An overview
It is specially designed for polycrystalline die polishing. It is quick when the polishing scope is over 0.35MM, saving grinding time to improve efficiency. It has advantages of high processing efficiency, good quality and low noise. It can be able to shape or polish quickly on die, and quickly make the processing side to reach mirror. In particular, it plays a significant role for large-sized mold processing.

B.   Technical parameters
Processing range (mm): 0.35-5.00
Power: 220V 50HZ
Maximum output power (W): 150
Transducer: Japanese nickel-chip inductive
Frequency (KHZ): 25
Die-seat speed (rpm / min): 180
Die-seat swing (time / min): 150
Swing angle: not less than 12 degrees (adjustable)

C.working principle and equipment constitutes
This machine uses ultrasonic high-speed vibration, and via the steel needle and abrasive to strike on the processed surface, grind processed surface to meet the needed shape and size. This equipment consists of ultrasonic generator, transducer and machine base.
(1) ultrasonic generator: ultrasonic generator is installed in a 450mm * 210mm * 410 mm iron box. Line uses automatic frequency tracking, correct automatically frequency of different steel needle to match each other, so as to achieve ultrasound output and shock effect.
(2) transducer: It is pure nickel film of water-cooling type with efficient transducer effect.The ultrasound can be converted into smooth ultrasound shock, using water cycle cooling, and has the characteristic of low noise.
(3) Machine base: Table can be rotated and can swing the machine base forward and backward. With a spring installed inside table, you can move it up and down, and it can adjust the pressure, swing it before and after by eccentric wheel and pulley. The swing margin is about 12 degrees. The platform was installed in the L-plate and can correct center to ensure die non-deformation and roundness in polishing process. The transducer is installed on a pair of board after the column which can be moved up and down.

D.Installation and Usage

(1)Installation. Place the machine base on balanced table, ascend and move the transducer to appropriate position and lock up, set aside the ultrasonic generator and grinding wheel machine, then connect the ultrasonic generator and transducer with output wire assigned by the machine.Insert the power supply plug on machine base into socket of power output on ultrasonic generator.After check-up, insert the power supply pin of ultrasonic generator into power supply socket with stable grounding wire under the condition of close of on-off.

(2)Usage. Choose appropriate steel needle based on the size of die processed. Sealed fast steer needle with silver welding rod to breadth changing pole .Then grind into suitable angles on grinding wheel and install and screw down on the transducer. Place the die on model base, adjust the cross board and dragging board of transducer to make the steer needle insert into the model pole, then put on abrasive, open up the switch of ultrasonic power and model base circumatation. Tune up the knob of export power of ultrasonic wave, the abrasive can be seen to stir under the function of ultrasonic wave. That means die processing or polishing is in operation

We can make the wire drawing machine,butt welding machine,pointing machine,layer winding machine,drum packing machine,flux cored wire forming machine and so on.
