Cold welding die structure for hydraulic cold welding machine device

Abstract

The utility model belongs to the technical field of hydraulic cold welding machines, and particularly relates to a cold welding die structure for a hydraulic cold welding machine device, which comprises a die table. Two vertical plates are fixedly connected to the top of the mold table; the two vertical plates are symmetrically arranged; a rotating hole is formed in the side wall of the vertical plate; the middle of the rotating hole is rotationally connected with a lead screw. The end part of the screw rod is rotationally connected with an extrusion plate; sliding grooves are formed in the opposite faces of the two extrusion plates. Two electric telescopic rods are fixedly connected to the inner side wall of the sliding groove. The two electric telescopic rods are symmetrically arranged; the end part of the electric telescopic rod is fixedly connected with a limiting plate; according to the structure, the mold can be fixed, and therefore the situation that the welding strength is affected due to the fact that the mold is unstable to be fixed on the top of the mold table, and the situation that during cold welding, due to the fact that the mold shakes, a welding seam deviates is reduced.
