Groove type rail frog welding seam normalizing device
The invention relates to the field of rail machining equipment, in particular to a groove type rail frog welding seam normalizing device. The groove type rail frog welding seam normalizing device comprises a mounting bracket, a cross beam, an induction electrode and an induction coil; the cross beam is rotatably connected with the mounting bracket, and the induction electrode is connected with the cross beam; the induction coil is connected with the induction electrode, and the induction coil is used for being arranged at the welding position of a connecting rail and a frog center in a sleeving mode and used for heating the connecting rail and the frog center. According to the groove type rail frog welding line normalizing device, the labor intensity of workers can be reduced, the heating quality after welding is improved, and the situation of uneven heating is avoided; and therefore, the heating temperature can be increased, poor grain size and reduced toughness of the welding seam are avoided, and the situation that the hardness of the surface near the welding seam of the groove type rail frog is uneven due to uneven heating can be avoided.
本发明涉及铁轨加工设备领域，具体而言，涉及一种槽型轨辙叉焊缝正火装置。槽型轨辙叉焊缝正火装置包括安装支架、横梁、感应电极以及感应线圈；横梁与安装支架可转动地连接，感应电极与横梁连接；感应线圈与感应电极连接，且感应线圈用于套设于连接轨与叉心的焊接处，并用于加热连接轨及叉心。该槽型轨辙叉焊缝正火装置能够降低工作人员的劳动强度，提高焊接后的加热质量，并避免出现加热不均匀的情况；从而能够提高加热温度，避免焊缝晶粒度较差和韧性降低，而且还能够避免因加热不均匀而导致槽型轨辙叉焊缝附近表面硬度不均匀的情况出现。
