Locally-embedded fork removing point rail
The invention relates to a local embedded type fork removing point rail which comprises a connecting part used for being connected with a wing rail and a pressure bearing part fixedly connected to the connecting part, a mounting groove is formed in the position, 20-50 mm away from the sharp corner of the pressure bearing part, of the pressure bearing part, caulking grooves are formed in the two sides of the connecting part in the width direction, and the caulking grooves communicate with the mounting groove to form a mounting cavity. The part, located between the two caulking grooves, of the connecting part is provided with a connecting core. An insert is further included, the insert comprises a connecting block and two side limbs, the two side limbs are arranged in a spaced mode and fixedly connected to the same end face of the connecting block, and a groove is defined by the side limbs and the connecting block; the connecting block is embedded into the mounting groove, the side limb is embedded into the embedding groove, the connecting core is embedded into the groove, a distance exists between the connecting core and the bottom of the groove, the insert is attached to the inner wall of the mounting cavity and connected with the connecting core, and then a closed air pressure chamber located above the connecting core is defined between the insert and the inner wall of the mounting cavity. And the service life of the easily damaged part of the point rail is prolonged in a targeted manner, and the machining workload after integral forging is reduced.
本申请涉及一种局部嵌入式撤叉心轨，包括用于与翼轨连接的连接部以及固定连接于连接部的承压部，承压部距离自身尖角20‑50mm之间设有安装槽，连接部宽度方向上的两侧均设有嵌槽，嵌槽与安装槽连通以形成安装腔，连接部位于两个嵌槽之间的部分设为联芯；还包括镶块，镶块包括连接块和两个侧肢，两个侧肢间隔设置且均固定连接于连接块的同一端面，侧肢与连接块合围形成凹槽；连接块嵌入安装槽内，侧肢嵌入嵌槽内，联芯嵌入凹槽内且与凹槽槽底之间存在间距，镶块与安装腔内壁贴合与联芯连接，进而镶块与安装腔内壁之间合围形成位于联芯上方的封闭气压室。有针对性提高了心轨容易受损处的使用寿命并减少整体锻造后机加工的工作量。
