Composition and characteristics of fully automatic multi line cold drawing machine:
The cold drawing machine is mainly composed of the loading platform, the receiving channel platform, the threading and pushing device, the core rod lifting platform, the core rod fore and aft adjustment device, the drawing die seat, the bed part, the drawing trolley, the main transmission device, the discharge conveyor chain device, the automatic finished product aggregate rack, etc.
When the detection device on the feeding platform fails to detect the pipe blank during the start of drawing, the lifting frame rises and rolls the pipe blank to the blocking device. When the detection device detects the pipe blank, the lifting frame automatically descends, and the baffle on the receiving groove rises. The rack and top device automatically distribute the pipe blank to the receiving groove of the receiving platform. The receiving groove has a certain slope and is equipped with rollers. When the cylinder rises, the pipe blank rolls to the blocking device. At this time, the pressing cylinder pushes out and presses the tail of the pipe blank. At this time, the core rod lifting platform rises to the center position of the threading rod, and the first stroke cylinder on the core rod seat pushes out the core rod into the inner hole of the pipe blank. After the core rod is threaded into the inner hole of the pipe blank, the receiving platform pushes it The material cart quickly passes the tube blank onto the core rod, and after it is threaded, the core rod lifting platform descends to the drawing center line. At this time, the first stroke cylinder automatically pushes out the three cylinders on the sliding plate The core rod, core rod, and billet puller are pushed through the die hole together. At this time, the pulling trolley, which is already waiting at the edge of the die, receives the first stroke in place control signal. The jaw cylinder pushes the jaw to clamp the billet head, and the main motor starts to drive the gearbox to the sprocket chain, driving the trolley to pull. At the same time, the second stroke cylinder is also pushed out to start pulling. At this time, the upper cylinder of the lifting and feeding device under the bed is pushed out, pushing the feeding device to the top. After the pulling is completed, the steel pipe falls onto the lifting and feeding device and descends. At this time, the conveyor chain on the discharge conveyor chain device moves, and when it descends to the conveyor chain, the finished pipe rolls into the automatically descending aggregate rack. The aggregate rack is equipped with a detection platform. When producing finished pipes, use buttons to control the cylinder to push the testing platform to a flat position for testing, At the same time, the pulling cart quickly returns to the edge of the mold seat to wait for the next automatic logic operation.
Its characteristics: This equipment is capable of drawing carbon steel pipes, bearing steel, low-alloy steel, stainless steel, copper molybdenum, and various non-ferrous metals. 2. The whole machine adopts the latest and simplest rolling technology design, which is easy to operate, reduces maintenance, and is convenient to maintain. 3. The cold drawing machine body adopts a double chain C-frame structure, and the center of the chain is consistent with the drawing center. 4. The mold seat is designed with a spherical shape, making it easy to straighten. 5. It is convenient to replace the jaws of the pulling trolley. 6. The main drive adopts a DC motor, which is energy-saving and stable. 7. The whole machine adopts PLC fully automatic control, with various parameter displays, safety interlocks, and alarm functions throughout the line. 8. The ideal reduction rate and pipe wall correction amount were achieved for each pass. 9. The inner and outer diameters and wall thickness can achieve extremely high required tolerance requirements and roughness. Technical parameters of inverted disc puller：
