Thin-walled tube simmering process and device

Abstract

The invention relates to a thin-walled tube simmering process and device, which belong to the field of pipeline production of thin-walled pipeline systems in the shipbuilding industry. The head end of the mandrel in the pipe fitting is at the start position of the simmering pipe, and the other end of the pipe fitting is clamped and fixed, which is the rear end; the placenta plate and the placenta block of the mold restrict the movement of the pipe fitting, and the movement of the mold block forces the pipe fitting to move toward the placenta plate Bending on the circumference, the head end of the mandrel moves to the front end with the bending of the pipe; during the bending process of the pipe, the force of the pipe is applied to the front end of the pipe, and the pipe is bent at any bending point, and the head end of the mandrel moves to the bending point synchronously The support tube bends. Its characteristic is to replace the elbows in each pipeline system, greatly reduce the weld joints in the pipeline system, improve the quality of the curved pipeline, and the thinning rate does not exceed 10%.

Description

technical field [0001] The invention relates to a thin-wall pipe stewing process and device, which belongs to the field of pipeline production of thin-wall pipeline systems in the shipbuilding industry. Background technique [0002] The pipeline made by the pipe-simmering device is characterized by replacing the elbows in each pipeline system, greatly reducing the weld joints in the pipeline system, and improving the quality of each pipeline system. At present, the domestic and imported pipe simmering machines have problems such as discounts and bulges when bending thin-walled pipes, which cannot meet the technical production requirements. Especially in the manufacture of copper-nickel B10 thin-walled piping systems for military ships, the thinning rate is required to be no more than 10%, which cannot be achieved with existing equipment. The working principle of the existing equipment is that the mandrel in the tube does not move by clamping the front end of the tube, and t...

AI Technical Summary

Problems solved by technology

At present, the domestic and imported pipe simmering machines have problems such as discounts and bulges when bending thin-walled pipes, which cannot meet the technical production requirements.

Especially in the manufacture of copper-nickel B10 thin-walled piping systems for military ships, the thinning rate is required to be no more than 10%, which cannot be achieved with existing equipment

The working principle of the existing equipment is that the mandrel in the tube does not move by clamping the front end of the pipe, and the tube rotates with the placenta during operation. When the tube rotates to a certain angle with the placenta, the mandrel in the tube does not work, resulting in discounted tube bends
