During the cutting process, the low-temperature resistant H-shaped steel will vibrate, so a rolling clamp is needed to limit the low-temperature resistant H-shaped steel;

[0003] Publication number CN205325058U discloses an H-steel positioning assembly fixture, which places an adjustable floating pad on the lower side of the web of the H-steel. The positioning size of the web is determined by adjusting the height of each adjustable floating pad. The upper flange plate of the H-steel is positioned by a movable limit seat, and the jack device on the base plate supports the lower flange plate of the H-steel. The movable limit seat and the jack seat are fixedly connected to the slider in the sliding groove on the base plate by fasteners, so that the upper flange plate and the lower flange plate of the H-steel can be limited to the left and right respectively. An end limit plate is provided on the top of the clamp, which can control the end size of the H-steel and adjust it through the other end. However, when the above-mentioned clamp is used to limit the position of the web of the H-steel during work, the position of the web of the H-steel is prone to shaking on the surface of the clamp during cutting, and is prone to offset during cutting.
