Cold-rolled wire online automatic rebar butt welding device

Abstract

The invention discloses a cold-rolled wire online automatic rebar butt welding device which comprises a pressing mechanism and an upset forging mechanism. The pressing mechanism comprises a fixing end and a moving end, wherein the moving end is driven by the upset forging mechanism to approach or apart from the fixing end. The fixing end and the moving end are respectively composed of cutting boards and downward pressing parts, the downward pressing parts are rightly opposite to the cutting boards, and arc grooves are arranged on the cutting boards which are electrodes. The cold-rolled wire online automatic rebar butt welding device can meet high speed, high efficiency and high automation production requirements of a high speed cold rolling production line, can automatically complete welding, and has good welding quality and high welding efficiency; and is installed on a roll steel section of the cold rolling production line, is simple in structure and convenient to use, does not move or shake in the butt welding process, and sufficiently meets requirements for welding quality.

Description

technical field [0001] The invention relates to the field of steel bar cold rolling, in particular to an on-line automatic steel bar butt welding device for cold-rolled wire rods used for butt welding two steel bar coils on a high-speed cold-rolled wire rod production line. Background technique [0002] In the prior art, on the high-speed cold-rolled wire rod production line, the wire rod coils to be rolled need to be welded together to facilitate rolling. The joints of the two coils are welded together. After the two coils are butt welded, the butt welding machine is used to weld the butt joints of the subsequent coils. The butt welding process is very inconvenient, and it is not only a great burden on the physical strength of the welding staff. In addition, in order to ensure the welding quality in the welding process, there are also high requirements for the operating accuracy of the staff. A slight movement or vibration will make the welding quality fail to meet the requ...

[0002] In the prior art, on the high-speed cold-rolled wire rod production line, the wire rod coils to be rolled need to be welded together to facilitate rolling. The joints of the two coils are welded together. After the two coils are butt welded, the butt welding machine is used to weld the butt joints of the subsequent coils. The butt welding process is very inconvenient, and it is not only a great burden on the physical strength of the welding staff. In addition, in order to ensure the welding quality in the welding process, there are also high requirements for the operating accuracy of the staff. A slight movement or vibration will make the welding quality fail to meet the requirements, thus affecting the rolling of the wire rod by the cold rolling production line. system
