Abstract

The invention discloses a large-tonnage double-end friction welding machine, which comprises a lathe bed. A guide rail face is arranged in the middle position of the upper surface of the lathe bed; a movable fixture is movably arranged on the guide rail face; welding machine devices with same structures are symmetrically arranged on two ends of the lathe bed; and the movable fixture can move back and forth towards the two welding machine devices. The invention further discloses a welding method of the large-tonnage double-end friction welding machine. According to the large-tonnage double-end friction welding machine provided by the invention, the welding devices with completely same structures are symmetrically arranged on the left side and the right side of the lathe bed, so that only one friction welding machine is needed for feeding at a time and clamping at a time so as to complete friction welding operation of a large-diameter non-excavation drill rod, the production efficiency is improved, the equipment capital investment is reduced, and the equipment floor space is reduced.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a large-tonnage double-head friction welding machine, and also relates to a welding method of the friction welding machine. Background technique [0002] The trenchless drill pipe is composed of the drill pipe body to be processed and the inner joint and outer joint welded at both ends of the drill pipe body to be processed. For non-excavation drill pipes, due to the large diameter of the welding parts, the long length of the drill pipe body to be processed, and the heavy weight, in order to facilitate operation, the traditional process method is to use manual electric welding and carbon dioxide gas shielded welding. Such fusion welding methods Welding manufacturing, but the welds at both ends of the drill pipe manufactured by this method have defects, the weld weight is poor, and the drill pipe is prone to breakage during use, which affects construction. ...
