Embodiment 1

[0041] Such as figure 1 As shown, the truss intersecting line welding production line of this embodiment includes a welding station 1 and an overturning station 2. The overturning station 2 is provided with an overturning device 21 for overturning the truss 3. The overturning device 21 can make the truss 3 wind around itself The axis of the truss is overturned, and a conveying device 4 for transporting the truss 3 is provided between the overturning station 2 and the welding station 1. During welding production, the welding station 1 welds the intersecting line on the bottom side of the current vertical side of the truss 3. After the welding is completed, the conveying device 4 transports the truss 3 to the turning station 2, and the turning station 2 The flipping device 21 flips the truss 3, so that the side of the truss is changed, and the side that is originally adjacent to the vertical side is flipped to a vertical position, so that the unwelded intersecting line is expose...

Embodiment 2

[0054] Such as figure 2 As shown, this embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, there are two welding stations 1, and a turning station 2 is provided between two adjacent welding stations 1 . During welding production, the two welding stations 1 can deliver the welded truss 3 to the flipping station 2 four times through the conveying device, or receive the flipped truss 3 from the flipping station 2. The setting method of this production line is similar. Compared with the one-to-one arrangement of welding station 1 and turning station 2, the waiting time of turning station 2 can be used to turn over the truss 3 that has been welded in another welding station 1, shortening the time required for turning over. The waiting time of station 2 improves the utilization rate of stations and further optimizes the production mode of the production line.

[0055] Correspondingly, in the welding method of welding truss intersecting line...

Embodiment 3

[0064] Such as image 3 As shown, this embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, there are four welding stations 1, three turning stations 2, and three turning stations 2 are respectively arranged in each Between two adjacent welding stations 1. During welding production, the truss 3 passes through the welding station 1, the turning station 2, the welding station 1, etc. in sequence along the production direction of the production line, until four times of welding and three times of turning are completed alternately. Compared with In embodiment 1, the interval time of putting into the truss 3 to be welded is only the time of the intersecting line on one side of the welding truss 3, which can realize a one-way production line, which is more in line with the production standard of the line type, further Increased production efficiency.

[0065] Correspondingly, the welding method for welding truss intersecting lines using the ...

Abstract

The invention discloses a welding production line and a welding method of a truss intersecting line. The production line comprises a welding station and an overturning station, the overturning stationis provided with an overturning device used for overturning a truss, and a conveying device used for conveying the truss is arranged between the overturning station and the welding station. The welding production line of the truss intersecting line has the advantages of being simple, practical, rapid, efficient, high in automation degree and the like, and the welding method for welding the trussintersecting line through the welding production line also has the above advantages.

Description

technical field [0001] The invention relates to the field of welding production, in particular to a truss intersecting line welding production line and a welding method. Background technique [0002] The truss is a structure connected by rods, which mainly bears axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save material, reduce self-weight and increase rigidity compared with solid web beams. [0003] The existing more common trusses include four main bars arranged at the vertices of a quadrilateral, and the adjacent main bars are connected by diagonal bars. During the welding process, the intersecting line between the main bars and the inclined bars needs to be welded fixed. However, the intersecting lines to be welded are distributed on four surfaces, and overhead welding cannot be performed. After welding the intersecting lines on the bottom side opposite to the welding torch each time, the truss nee...
