Abstract

The invention relates to a large-variable-diameter thin-wall pipe composite forming device. According to the technical problem to be solved, the large-variable-diameter thin-wall pipe composite forming device can achieve large-variable-ratio formation, and is high in production efficiency. The large-variable-diameter thin-wall pipe composite forming device comprises a rack, a first motor, a transmission device, a transmission shaft, a first clamping device, a first push-pull device, a connecting disc and a second clamping device. The first motor is fixedly installed on the bottom of the rack.The output end of the first motor is connected with the transmission device. The output end of the transmission device is connected with the transmission shaft. The other end of the transmission shaftis fixedly connected with the first clamping device. The first push-pull device is fixedly installed on the top of the rack. The output end of the first push-pull device is connected with the connecting disc. The connecting disc is fixedly connected with the second clamping device. The large-variable-diameter thin-wall pipe composite forming device achieves the effects that thin-wall pipe large-deformation-ratio deformation is convenient and the production efficiency is high. By means of reasonable device layout, the device is simple in structure, and easy and efficient to operate.

Description

technical field [0001] The invention relates to a forming device, in particular to a compound forming device for a thin-walled pipe with large variable diameter. Background technique [0002] The manufacture and application of pipes occupy an important position in the manufacturing industry. Compared with solid steel such as round steel, steel pipes are lighter in weight when they have the same flexural and torsional strength, and are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts and bicycle frames. Steel pipe is also an indispensable material for various conventional weapons, and steel pipes are required for the manufacture of gun barrels and barrels. Lightweight structure is one of the main means for vehicles, airplanes and rockets to save fuel, reduce pollutant emissions and improve maneuverability. As "energy saving and environmental protection" is getting more and more attention, lightweight i...
