Embodiment Construction
[0020] A toothed multi-pole corrugated pallet bridge bottom plate for projection welding according to the present invention is characterized in that the corrugated pallet bridge bottom plate includes a bottom plate 1, a bottom plate protrusion 11, a bottom plate protrusion end tooth profile 111, and a bottom plate groove 12. The bottom plate 1 is formed of a corrugated shape by continuously setting the bottom plate protrusions 11 and the bottom plate grooves 12 at intervals. A plurality of convex points are respectively arranged on the two sides of the bottom plate protrusion 11 to form a tooth profile 111 on the end surface of the bottom plate protrusion. For welding with the side plate of the bridge frame. said in tile
[0021] The two sides of corrugated bottom plate 1 correspond to the parts to be welded side plates,
[0022] All are provided with a plurality of protruding points to form the tooth shape 111 of the protruding end surface of the bottom plate.

The invention discloses a tooth-shaped multi-pole corrugated tray bridge base board for projection welding, the tooth-shaped multi-pole corrugated tray bridge base board comprises a base board (1), abase board projection (11), a base board projection end face tooth profile (111) and a base board groove (12), a corrugated base board (1) is constituted by continuously arranging the base board projection (11) and the base board groove (12) at intervals; a plurality of projection points are respectively arranged on both sides of the base board projection (11) to form the base board projection endface tooth profile (111) for being welded with the side plate of the bridge. By the tooth-shaped multi-pole corrugated tray bridge base board, production processes of the light-weight enhanced tray cable bridge base board and T-shaped connection projection welding of the side plate are ensured to be achieved, so that the problem of T-shaped connection welding of the light-weight enhanced bridge sheet is solved, the problem that hot-dip galvanized steel plates and stainless steel plate need restore corrosion resistance and appearance quality through surface treatment after being welded is solved, and pollution in the surface treatment process is avoided.
Description
technical field [0001] The invention relates to a tooth-shaped multi-pole corrugated tray bridge bottom plate for projection welding, which belongs to the technical field of electrical accessories. Background technique [0002] Since the base plate of the light-duty enhanced tray-type cable tray adopts a concave-convex corrugated structure, the base plate and the side plate need to be fabricated separately and then assembled into a whole. When the side plate and the bottom plate are assembled, the end surface of the bottom plate must be T-shaped with the side plate plane. At present, the welding process used for the T-shaped connection assembly of the bottom plate and side plate of the cable tray is gas shielded welding, and the filler wire is melted and welded by pulse short circuit. Since the cable tray is made of thin plates, this welding method often causes arcing instability. The phenomenon of welding leakage or welding penetration is easy to occur, which has a great im...
