Summary:The utility model discloses a novel steel rail bending device which comprises a top head and a back plate arranged on one side of the top head, the other side of the top head is provided with a pressing curved surface matched with the waist of a steel rail in shape, and the back plate is connected with a back plate socket and is connected with an oil cylinder of a hydraulic machine through the back plate socket. Therefore, through the specially designed steel rail bending device, the arc of the ejected steel rail is smoother, no sharp corner exists, the steel rail is more in line with the drawing size, and the ejected steel rail is not prone to bending up and down. The problems that vertical bending occurs due to the difference of goodness of fit in a traditional top bending mode, repeated adjustment is needed, and the top bending angle needs to be verified after adjustment is completed are solved. 本实用新型专利公开了一种新型钢轨顶弯装置，包括顶头及其一侧带有的后背板，该顶头另一侧具有一个与钢轨腰部形状相吻合的顶压曲面，所述后背板与背板插座连接，通过背板插座与液压机的油缸连接。因此，通过专门设计的钢轨顶弯装置，具有顶出
