Abstract
The invention relates to the field of resistance welding machines, in particular to a resistance butt welding machine die provided with a core rod. The resistance butt welding machine die comprises a main die, a subsidiary die and the core rod. The main die is constituted by a first upper die and a first lower die which are identical with each other in appearance. A first titanium alloy layer is arranged on the welding face of the first upper die, and a second titanium alloy layer is arranged on the welding face of the first lower die. The subsidiary die is constituted by a second upper die and a second lower die which are identical with each other in appearance. Cylindrical slide rails are connected with the second lower die. A slide sleeve is arranged on the cylindrical slide rails. The core rod is mounted on the slide sleeve. According to the resistance butt welding machine die, the titanium alloy layers are arranged on the welding faces of the main die, wherein the titanium alloy layers have the beneficial effects of being high in strength, good in corrosion resistance, high in heat resistance and the like, so that the service life of the die is greatly prolonged. The core rod is used for guaranteeing that at the resistance butt welding upsetting stage, oxides extruded at a copper-aluminum joint are regularly arranged and distributed under the action of the core rod, and thus the oxides are prevented from blocking weld beading in a pipe.
