Description
Technical Field
The invention relates to a cable ladder frame adopting multi-pole point salient point T-shaped connection projection welding, belonging to the technical field of electrical accessories.
Background
Because the crosspiece and the side plates of the cable ladder frame need to be manufactured separately and then assembled into a whole, when the side plates and the crosspiece are assembled, the end faces of the crosspiece must be connected with the plane of the side plates in a T shape, the welding forming process used for the T-shaped connection and assembly of the crosspiece and the side plates of the cable bridge frame at present is arc welding or gas shielded welding, filler wires are melted and welded through pulse short circuit, the welding mode often has the phenomenon of unstable arc striking, welding leakage or welding penetration is easy to generate, the continuity and the reliability of welding are greatly influenced, the gas shielded welding is hot-melt welding, the efficiency is low, the energy consumption is high, the deformation of workpieces is large, the precision cannot meet the requirement, holes and welding marks caused by overheating are often generated outside the welding position of the side plates, and particularly when hot-galvanized steel plates and stainless steel plates with corrosion resistance are selected as materials, the arc welding or the gas shielded welding, the welding position is oxidized, the corrosion resistance of the welding position is damaged, the quality and the whole appearance of a product are influenced, the requirements of the corrosion resistance and the appearance consistency are met through surface treatment, the product cost is increased through the surface treatment, and the environment is inevitably influenced and even polluted in the surface treatment process.
The resistance projection welding is used for T-shaped connection welding, has small energy consumption, high efficiency, stable performance and small influence on the appearance of a product, can meet the technical requirements of the T-shaped connection welding of a cable ladder frame, but the structure of the existing ladder frame side plate cannot be used for the resistance projection welding, so the invention of the side plate structure which can be used for the resistance projection welding and meets the T-shaped connection requirements is a problem to be solved urgently in the welding and bridge frame industry.
Disclosure of Invention
The technical problem is as follows: the invention aims to provide a cable ladder frame adopting multi-pole T-shaped connection projection welding, which solves the problems of production efficiency and quality of T-shaped connection welding of hot-dip galvanized steel plates and stainless steel plates.
The technical scheme is as follows: the cable ladder frame adopting the multi-pole T-shaped connection projection welding comprises side plates, side plate salient points and crosspieces; a plurality of salient points are arranged at the inner side of the side plate corresponding to the positions of the crosspieces to be welded to form side plate salient points; the two ends of the crosspiece are respectively connected with the positions of the side plate salient points on the two side plates to form the cable ladder frame.
Wherein,
the inner side of the side plate corresponds to the part of the crosspiece to be welded, and the convex points of the side plate are arranged according to the cross section shape of the crosspiece to be welded.
The side plate salient points are formed by punching a plurality of salient points from the outer side to the inner side on the side plate.
The side plate salient points are composed of a plurality of continuous salient points.
The side plate salient points are composed of a plurality of discontinuous salient points.
The salient points of the side plates are triangular.
The salient points of the side plates are semicircular.
The side plate section of the ladder frame is cut into required length according to the requirement of the specification and the length of the bridge frame, a plurality of salient points are punched from the outer side to the inner side at the corresponding positions of the side plates according to the number and the positions of the crosspieces, and the size, the shape and the number of the salient points are set according to the requirement of the end faces of the crosspieces. When the end face of the crosspiece of the ladder frame is contacted and compressed, the side plate salient points are input with current through a power supply, and the resistance is increased instantly under the action of large current due to the fact that the conductive contact surface of the side plate salient points and the end face of the crosspiece is small, and the contact part generates an overheat reaction to form a punctiform continuous welding surface, so that the side plate and the crosspiece are firmly welded into a whole.
Has the advantages that: the cable ladder frame adopting the multi-pole-point convex-point projection welding ensures the realization of the production process of the T-shaped connection projection welding of the crosspiece and the side plate of the cable ladder frame, solves the problems existing in the T-shaped connection gas shielded welding of the galvanized steel plate and the stainless steel plate ladder frame, simultaneously solves the difficult problem that the corrosion resistance and the appearance quality are required to be recovered through surface treatment after the welding of the galvanized steel plate and the stainless steel plate, and avoids the pollution in the surface treatment process. The product is more attractive, the production efficiency is 7-10 times of that of the existing gas shielded welding, the energy consumption is reduced by 40%, wire filling is not needed, the production cost is reduced, the product is green and environment-friendly, basically does not deform, has no craters and welding slag, is high in precision and attractive in appearance, and the product quality is greatly improved.

Detailed Description
The cable ladder frame adopting the multi-pole T-shaped connection projection welding comprises a side plate 1, side plate salient points 11 and a crosspiece 2; a plurality of salient points forming side plate salient points 11 are arranged at the inner side of the side plate 1 corresponding to the positions where the crosspiece 2 needs to be welded; the two ends of the crosspiece 2 are respectively connected with the positions of the side plate salient points 11 arranged on the two side plates 1 to form the cable ladder frame. The inner side of the side plate 1 corresponds to the part of the crosspiece 2 to be welded, and the side plate salient points 11 are arranged according to the shape of the cross section of the crosspiece to be welded. The side plate salient points 11 are formed by punching a plurality of salient points from the outer side to the inner side on the side plate 1.
The side plate salient points 11 are composed of a plurality of continuous salient points or a plurality of discontinuous salient points.
