Problems solved by technology

[0004]Induction heated normalizers generally require a rail clamping operation to position the induction heated normalizer prior to normalizing, for example, a welded joint on a rail. Lighter, so as to realize the positioning of the coil used to envelop the rail relative to the welded joint. In this way, the positioning accuracy of the induction heating normalizing machine on the rail is high, and the coil during the induction heating normalizing treatment is not considered at all. special targeting requirements

Abstract

The invention provides a normalizing machine, and belongs to the technical field of railway engineering machinery. The normalizing machine comprises: an open-close type induction coil device, wherein the open-close type induction coil device is used for carrying out induction heating on a welding joint on a profile so as to complete normalizing treatment; a clamping and centering device, wherein the clamping and centering device is used for clamping the profile at the front position and the rear position of the welding joint at the same time and centering the clamped profile; and a coil opening, closing and translating device, wherein the coil opening, closing and translating device is used for driving the opening and closing type induction coil device connected to the coil opening, closing and translating device to perform opening and closing actions and moving the induction coil device parallel to the profile in the front-back direction of the welding joint so as to be aligned to a welding seam of the welding joint, the clamping and centering device which has clamped and centered the profile provides positioning for the coil opening, closing and translating device, and the coil opening, closing and translating device drives the induction coil device to move in the front-back direction of the welding joint on the basis of the positioning. In the normalizing machine, the alignment precision of the coil relative to the welding joint is high, and the normalizing treatment effect is good.

Description

technical field [0001] The invention belongs to the technical field of railway engineering machinery, and relates to a normalizing machine, a rail on-site normalizing operation system including the normalizing machine, and a rail on-site operation assembly including the rail on-site normalizing system. Background technique [0002] In the construction or maintenance process of rail transit, the corresponding heat treatment operation is required after the rail is welded. For example, the corresponding industry standard requires the heat treatment process of normalizing the welded joint after the welding operation, so that the normalizing treatment can greatly improve Weld joint performance. [0003] Generally, the rail on-site normalizing operation system is used to complete the normalizing operation process of the welded joints of the rail on-site or on-line. The on-site normalizing operation system for rails includes induction heating normalizing machines and supporting la...
