Abstract
The invention relates to a bend-forming method for a flexible supporting tubular product and a technological method thereof. The forming efficiency is high, the surface quality of the formed tubular product is good, and the application range is wide. The bend-forming device comprises a heating cover, a hydraulic cylinder, a left plug, a tube blank, a moving die adjustment lever, a fixed block, a moving die, particulate matter, a right plug, an ejector rod, a fixing clamp, a fixed wheel female die, a turnplate and a workbench. In the bend-forming process, the stability of the tube blank is guaranteed by applying pressure to the particulate matter charged in the tube blank, the dies and a pressing device rotate synchronously, and various tubular products with the outer diameter being 20-100 mm, the wall thickness being 0.2-2 mm and the bending angle being 0-3,000 degrees can be bend-formed rapidly. Hot bend-forming can also be conducted on materials hard to deform through the heating cover.
Description
technical field [0001] The invention relates to the field of building material forming, in particular to a flexible supporting pipe bending forming device and a process method thereof, especially suitable for the preparation of thin-walled large-caliber and high-strength pipe bending parts. Background technique [0002] The bending of ordinary pipes usually adopts techniques such as stretch bending, winding bending, and push bending. During the bending process of the tube blank, a fixed core is placed inside to support the inner wall of the tube blank and prevent the tube from being unstable. However, for the forming of thin-walled, large-diameter, and high-strength tube blanks, it is difficult to guarantee the bending quality by ordinary bending methods, especially for forming tubes with large bending angles. Contents of the invention [0003] In view of the above problems, the present invention provides a novel flexible supporting pipe bending forming device capable of f...
