The cold drawing machine adopts bed structure, which can be divided into three-seat wide type and frame type; according to the transmission mode, it can be divided into chain type, hydraulic transmission type, rack type, screw type and other types of pullers. The drawing trolley of the cold drawing machine is maintained by two I-type guide rails, driven by the main oil cylinder, so that the trolley runs along the I-type guide rails. The main oil cylinder and the traction trolley can pass through the adjustable split piston and the trolley body, and the axial direction remains unchanged. When the cold drawing machine pulls out the steel pipe, first insert the mandrel into the inner hole of the steel pipe, then install the mandrel head, and then push the front end of the steel pipe with the mandrel head out of the draft seat. Start the pre-tightening cylinder so that the mold clamps the steel pipe, the drawing trolley is in the initial position, and the main cylinder starts the initial drawing. At the end of the drawing, preload the cylinder. The mold releases the steel pipe fork to push the drawn product pipe out of the car body. At the same time, the slider moves to the opposite target, so that the plug is quickly drawn out of the pipe for smooth feeding.
The cold drawing machine is a non-sliding dry continuous wire drawing machine with an integrated production line. During the drawing process, there is no relative sliding between the steel wire in the circumferential direction of the drum and the surface of the drum along the circumference of the drum. Its surface wear is relatively small, and it has the advantages of simple structure, simple operation and maintenance, low manufacturing cost, and a certain product line coefficient. The steel wire stays on the drum for a long time, which is conducive to sufficient cooling of the steel wire. In the process of drawing with a cold drawing machine, we all hope that the device can always maintain a stable shape. If you want to ensure the safe and stable operation of the cold drawing machine, you must first ensure that it is installed correctly. The second is to ensure the correct operation of the cold drawing machine. Other than that, you have other options. For example, during the operation of the equipment, attention should be paid to its detection. Of course, it is also necessary to do a good job of dredging to ensure its normal operation.
