Problems solved by technology

[0002] Prestressed steel bars are widely used in key projects such as railways, bridges, energy, metallurgy, and construction. With the rapid development of the wire processing industry, especially the wide application of prestressed steel bars, the technical requirements for prestressed steel bar cutting machines are also constantly improving. , the existing prestressed steel bar cutting machine technology and products are far from meeting the requirements of the rapid development of prestressed steel bar processing industry
The existing prestressed steel bar cutting machine has the following problems: the transmission and cutting mechanism of the prestressed steel bar cutting machine currently used is complicated, and there are many wearing parts, which increases the cost of use, maintenance and processing; Helping work hours; the walking speed of steel bars is low, which affects production efficiency; the power of the cutting mechanism is large, which saves effort and wastes energy
