Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] like figure 1 , figure 2 As shown, the present invention is used to overhaul the slave plate of the No. 13 coupler buffer device of railway wagon, which includes a slave plate 1 and a rectangular wear plate 2, the wear plate 2 is welded on the side of the slave plate 1, and the overall width of the wear plate 2 is less than From the thickness of the side end of the plate 1, the length of the wear plate 2 is smaller than the width from the end of the plate 1.
[0018] In the above-described embodiment, the four corners of the slave board 1 are rounded (such as image 3 As shown), the forging natural forming process is simple in this way, it is convenient to assemble on the car, and it is not easy to bump and hurt the operator, and it is not easy to hurt other accessories after being assembled from plate 1 and put on the car.

The invention relates to a method for repairing slave plates of rail wagons and an abrasion-resistant plate for repair. The method includes steps of (1), examining whether the slave plates have cracks or not, abandoning the slave plates with cracks, and adopting a slave plate without cracks to continue to a next step; (2), examining whether abrasion depths of six surfaces of the slave plate without cracks exceed 2mm or not, and continuing to a next step if the abrasion depth of any one surface of the slave plate without cracks exceeds 2mm; (3), heating and re-forging the slave plate with excessive abrasion, and continuing to a next step after forging is qualified; (4), shearing the abrasion-resistant plate into a plate with a preset specification by a plate shearing machine; (5), measuring the length of the slave plate forged qualifiedly in the step (3), and welding the abrasion-resistant plate with the corresponding thickness on the slave plate according to the length; and (6), examining the size of the slave plate after being welded and installed with the abrasion-resistant plate, and normally using the slave plate if examination is qualified. The method can ensure repair quality of the rail wagons, cost is low, and the structure is simple. The method can be widely applied to repair application of rail wagons.
Description
technical field [0001] The invention relates to a wear plate for a railway freight car and an overhaul method, in particular to a method for overhauling a secondary plate of a No. 13 coupler buffer device of a railway freight wagon and the wear plate for overhaul. Background technique [0002] In order to ensure the safe operation of railway wagons, the No. 13 coupler buffer device for railway wagons requires that the secondary plate be replaced when it is cracked; when the wear of each part of the secondary plate is greater than 2mm, it must be processed after surfacing, and when the wear of the side (length direction) is greater than 2mm, it can be Weld wear plate, adjust and repair when bent and deformed. However, the material of the slave board is Q275, which has poor weldability. According to statistics, about 60% of the sub-plates used for the buffer device of the No. 13 coupler of railway freight cars need to be welded and repaired due to the wear and tear of each pa...
