Stock rail structure for obtuse angle combined frog and machining method of stock rail structure
The invention provides a stock rail structure for an obtuse-angle combined frog and a machining method thereof. The stock rail structure comprises the stock rail structure for the obtuse-angle combined frog. Stock rails of the stock rail structure are made of 60TY1 steel rails with asymmetric sections; one side, wider from the center line, of a stock rail head of the stock rail structure is used as a working side; the machining method of the stock rail structure comprises the steps that rough machining is conducted firstly, then top bending is conducted, and finish machining is conducted. Or the machining method of finish machining first and then top bending is adopted. The alloy steel obtuse angle combined frog solves the technical problems that an existing alloy steel obtuse angle combined frog is relatively complex in structure, inconvenient to assemble, limited in abrasion resistance and strength and relatively short in service life. The structure and the method scheme are relatively simple, machining, manufacturing and assembling are easy, the structure is relatively more stable and safer, smoothness is good, the service life is long, and the railway market requirement is met.
提供一种钝角组合辙叉用基本轨结构及其加工方法，包括钝角组合辙叉用基本轨结构；基本轨结构的基本轨采用非对称断面60TY1钢轨制造；基本轨结构的基本轨轨头距中心线较宽的一侧用于工作边；基本轨结构的加工方法为：采用先粗加工、后顶弯、再精加工的方法完成；或采用先精加工、后顶弯的加工方法完成。本发明解决目前合金钢钝角组合辙叉结构相对复杂，不便组装，耐磨性和强度有限，寿命相对较短的技术问题；结构以及方法方案相对简单，易于加工制造及组装，结构相对更加稳定、安全、平顺性好，使用寿命较长，满足铁路市场需求。
