Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:

[0033] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , the welding method of the mirror thin plate in the bridge bearing sliding plate assembly of the present invention, comprises the following steps:

[0034] A. Cutting

[0035] The mirror thin plate 1 for the sliding plate assembly of the multi-directional support is obtained by shearing and blanking with a shearing machine, or after shearing and blanking with a shearing machine, the side corresponding to the concave groove 4 on the sliding plate 2 is pressed into a right-angled shape to obtain Mirror sheet 1 for lateral and longitudinal support slide plate assembly. Use a file to file and deburr the periphery of the mirror sheet 1, and then finely grind the periphery of the mirror sheet 1 with a whetstone;

[0036] B. Marking and...

Abstract

The invention relates to a method for welding a mirror surface lamella of a bridge support sliding panel assembly. The invention comprises the following technology procedures: baiting, lineation and location, deformation preventing treatment and tungsten electrode gon arc intermittent welding without filling welding wires. The method has simple frock structure, low manufacture cost, convenient use, and good commonality. A mirror surface lamella (1) has tiny welding deflection, and has small clearance with a basal body sliding panel (2), therefore, the welding line is not superelevation, the mirror surface (1) of the lamella is not destroyed, and the rate of finished products of welding and machining is greatly increased. The method is simple, easy to popularize and is applicable to other occasions of lamella welding.

Description

technical field [0001] The invention relates to a welding process, in particular to a welding method for a mirror thin plate in a sliding plate assembly of a bridge basin type rubber bearing. Background technique [0002] The pot rubber bearing is an important component of the railway bridge, which connects the bridge and the pier, and plays an important role in connecting the preceding and the following. The component in the basin rubber bearing—the sliding plate assembly involves the welding of the mirror stainless steel sheet. The main welding methods are as follows: ①. In the multi-directional bearing, the mirror stainless steel in the sliding plate assembly The thin plate is welded on the surface of the sliding plate, such as figure 1 , figure 2 As shown; ②, in the horizontal and vertical bearings, the mirror stainless steel in the sliding plate assembly is pressed into a right-angle shape and then welded on the surface of the sliding plate processed into a concave g...
