Equipment for twisting steel wires into rope strands. The twisting machine is composed of main components such as transmission device, twisting body, wire pressing tile device, traction device, safety and parking device, wire winding device, as well as a series of auxiliary machinery such as crane, welding machine, cutting machine, etc. The commonly referred to twisting machine refers to its main body and does not include auxiliary machinery. Twisting machines have several types of machine structures, including basket type, tube type, and non tube type.
The tube twisting machine is composed of one or several sections of a cylinder body. The load line I-shaped wheels are arranged in a zigzag pattern along the center of the machine body; Always maintain a horizontal position when laying out the I-shaped wheel; The high-speed rotation of the cylinder, combined with the linear traction generated by the traction device, causes the steel wire to spiral and move in a straight line, forming a strand with a certain twist distance, thus completing the basic twisting action of the strand. Compared with basket type machines, the twisting principle is the same, but the structure has significant improvements. The tube type twisting machine has a small simplified volume, low center of gravity, small moment of inertia, fast operating speed, low noise, smooth operation, and convenient operation. It is suitable for twisting most rope strands, especially wire contact steel rope strands and steel strands. Add some specialized devices, and can also lay surface contact steel wire rope strands and irregular strands. The rotational speed of the tube type strand twisting machine can reach 400-5000r/min. According to the number of cylinder sections and the size of equipment power, it can form a strand twisting machine with 6-36 I-shaped wheels, up to 48 I-shaped wheels, and the body can reach up to 60m. The outer diameter of the I-shaped wheel of the tubular machine is 100-630mm.
