Product Name: Aluminum Tube Automatic Three-Thread Drawing Machine 

Specification: FR-10 

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 double-chain type 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 vibration be minimal, the drawing speed be uniform and stable, and the best precision of the finished product after stretching be achieved. The finished product should have a uniform, smooth surface and good quality. Usually, the above requirements are met after the stretching process. 

3. Equipment Capacity 

A. Stretching Form 1 - Linear Stretching 

B. Tensile force: 150 KN 

C. Stretching speed: 0 - 12 m/min 

D. Stretch length: 9 meters 

E. Length of the extraction tube (propeller length) Effective length: 8 meters 

F. The outer diameter of the pipe is the maximum 100mm and the wall thickness is 2.5mm. 

G. Center height: 800mm 

4. Machine Construction 

A. Motor and Control Panel 

(1) One type of excitation speed-regulating motor with a power of 45KW; one reducer model ZQ-850 with a ratio of 1:48.75; 15:11 small vehicle speed-regulating motor with a power of 2.2KW. 

(2) Effort 

(3) Rotational speed 

(4) Power supply voltage: 380V, 50 - 60Hz 

5. Driving Section 

(Rack C360C160 steel channel and flat steel 30*40 are used for welding the main rack: C360*12000, extruded rack C360*10000) 

(2) Chain 48B-2 Taiwan Chain 

(3) Chain wheel shaft Φ125 

6. Construction of the supporting part 

(Slot base spherical template, diameter 260mm) 

(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. 

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

(7) Automatic cutting is not available 

(8) 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.
