Obtuse-angle alloy steel combined frog and machining method thereof
The invention provides an obtuse-angle alloy steel combined frog and a machining method thereof. The frog comprises a stock rail of a welded structure and a point rail which is integrally forged and is of a symmetrical structure. According to the stock rail of the welded structure, a rail made of a high-abrasion-resistance material is welded to the middle section of the stock rail. The technical problems that in the prior art, an obtuse angle combined frog is not beneficial to efficient and batch machining in a factory, the cost is high, the structural stability and stress balance are poor, the service life is short, and abrasion resistance is not achieved are solved. By the adoption of the technical scheme, efficient batch machining in a factory can be achieved, cost is effectively reduced and controlled, the structure is stable, and stress is balanced; the vehicle passing abrasion loss on the two sides of the fork heel guard rail and the fork heel rail is improved, and the service life is long; the service life of the frog is prolonged, and driving safety of working sides of the frog is guaranteed.
提供一种钝角合金钢组合辙叉及其加工方法，包括钝角合金钢组合辙叉；辙叉包括焊接式结构的基本轨和整体锻制而成且为对称结构的心轨；焊接式结构的基本轨在基本轨中间段焊接高耐磨性材质轨。本发明解决现有技术下钝角组合辙叉不利于工厂内高效批量化加工、成本高、结构稳定性、受力均衡性不佳，寿命短、不耐磨耗的技术问题；采用本发明技术方案，可实现工厂内的高效批量加工，有效降低并控制成本，结构稳定，受力均衡；提高叉跟护轨、叉跟轨两侧过车磨耗量，寿命持久；提高辙叉使用寿命，保证辙叉工作边行车安全。
