The invention provides a pipe bending machine, comprising: a main shaft and a mold fixedly connected with the side of the main shaft, and a driving structure fixedly connected with the end of the main shaft; There are a plurality of moving molds, and the fixed mold is provided with a continuous fixed mold contact surface, and the corresponding positions of the multiple mobile molds are provided with a continuous mobile mold contact surface, and after the fixed mold is fixedly connected with the multiple mobile molds, The contact surface of the fixed mold can be seamlessly fastened with the contact surface of the movable mold to form a spinning pipe channel. The solution provided by the present invention forms a spinning tube channel by setting a fixed mold with a continuous curved surface and a moving mold, so that the spinning tube can be bent and produced in the spinning tube channel, and because the curved surface is continuous, so, The curve of the spinning tube can be precisely controlled to ensure a smooth transition of the curve of the spinning tube, and the curvature is continuous without fluctuation, so that a high-precision spinning tube can be obtained.
Description
technical field [0001] The invention relates to the technical field of spinning pipe bending and forming equipment, in particular to a pipe bending machine. Background technique [0002] The laying machine is an important equipment in the high-speed wire production line unit. Its main movement process is: the motor transmits the rotational motion to the hollow shaft of the laying machine through a pair of spiral bevel gears. The steel rolled and formed by the high-line finishing mill is pinched by the pinch roller, enters the hollow shaft of the high-speed rotating laying machine, and then penetrates into the spinning tube, and is deformed by force through the spinning tube. The steel material changes from a high-speed linear motion into a nearly stationary circle, scattered on the air-cooled roller table, and then packed into a wire coil, which is commonly known as a wire rod. [0003] The part in the laying machine that deforms the wire into a loop is the laying tube, whi...
