Fully automatic drawing machine-------------------------------------------------------------------------------------Suitable for drawing of metal tubes (rods) 

Product Name: Drawing Machine 

Specification: FR-80 type 

1. Equipment Overview 

A. This equipment is applicable to the processing of metal tubes (rods) for stretching (pulling, cold drawing, polishing, embossing) operations. 

B. Mechanical structure single-chain drawing machine - Taiwan brand drawing machine technology 

2. At one end of the working material, after being reduced (compressed) by the head (pressing head), it is held by hand and inserted into the center frame mold of the drawing machine. After being pneumatically clamped, the chain hook engages with the chain for drawing. During the drawing process, it is required that the machine body has minimal vibration, the drawing speed is uniform and stable, and the best precision of the finished product after stretching is achieved. The finished product has a uniform, smooth and good quality surface. Usually, the above requirements are met after the stretching process. 

3. Equipment Capacity 

A. Stretching Form 1 - Linear Stretching 

B. Tensile force: 10 tons 

C. Stretching speed: 0 - 25 m/min 

D. Stretch length: Effective length 9000mm 

E. Length of the extraction tube (propeller length) Effective length: 8000mm 

F. The outer diameter of the pipe is the maximum 80mm and the wall thickness is 3.5mm. 

G. Center height: 830mm 

4. Machine Construction 

A. Motor and Control Panel 

(1) One 45KW variable-frequency inverter for the excitation speed control machine, one 37KW motor, ZQ2-650 type, 1:48.571, one trolley deceleration motor, 1HP, 10:11. 

(2) Output 189 

(3) Rotational speed: 1320 - 132 revolutions per minute 

(4) Power supply voltage: 380V, 50Hz 

5. Drive the main shaft 

(1) Rack C300C120 square steel with 35*35 precision track. Main rack: C300*11200. Extruded rack: C300*9000. 

(2) 3-inch chain  Taiwan chain 

(3) Chain wheel shaft Φ80 

6. Construction of the supporting part 

(Slot base spherical template, diameter 142.5mm) 

(2) Steel plate welding structure of the mold installation frame (push-in rod for the internal mold of the cylinder) 

(3) The cylinder arm of the receiving device rotates to receive materials. 

(4) The feeder is equipped with a manual loading function. If an automatic feeding device is required (rolling into a sliding groove, the reducer motor pushing into the ejector mold, the ejector mold automatically rising and inserting into the material, then lowering to the horizontal position, and being pushed into the drawing mold by the tailstock cylinder), an additional cost of $30,000.00 will be incurred. 

(5) Pneumatic clamping device for the pulling cart, clamp-type arm, pneumatic chain hook, return vehicle chain drive with speed reduction mechanism 

(6) Automatic cutting is not available 

(7) The oil injection method involves high-pressure and high-temperature oil pumps, and the oil is simultaneously pumped by both the inner and outer molds.
