The invention discloses an anti-side-rolling straight-bar square-cone torsion bar for rolling stock. The torsion bar comprises a torsion bar body, a connecting part of two ends of the torsion bar body and a rocker arm is a polyhedron obtained by cutting a quadrangular pyramid of which the center line coincides with the axis of the torsion bar and the vertex is positioned at the side far away from the torsion bar; the taper of the quadrangular pyramid is 1: 10 or 1: 16 or 1: 20, and the rocker arm is provided with a combination surface matched with the connecting part of the torsion bar body. The invention further provides a machining process of the anti-side-rolling torsion bar of rolling stock, and the machining process comprises the steps that the torsion bar body is subjected to thermal refining after rough machining, and shot blasting is conducted on the surface of the torsion bar body. According to the anti-side-rolling torsion bar for rolling stock, a face contact kinematic pair structure is adopted, the connection strength is greatly improved, higher safety coefficient is guaranteed, the assembly process is simple, and the torsion resistance and compactness are improved.
