Description
Technical field
The present invention relates to a kind of pipe bending technique, the quick cold drawn curved technology of more particularly to a kind of thin-walled smaller part diameter pipes.
Background technology
Bend pipe is bent using complete bending mould, is divided into cold stewing and is picked two kinds of techniques.Minimum bending radius
Depending on the corrugated size of the thinning allowance on the outside of material property, angle of bend, tube wall after bending and inner side and bending
The size of the ovality at place.The method of current bend pipe is typically difficult to be applied to thin-walled smaller part diameter pipes, such as mm × 1 of φ 10
Mm, φ 20 mm × 1 mm and φ 30 mm × 1 mm equal-specifications tubing.
Current someone is bent using the method for perfusion rosin for thin-walled smaller part diameter pipes, irrigates the method for rosin just
It is in the stainless steel tube for filled in after rosin is melted thin-walled minor radius, to be bent after rosin is chill, again by pine after bending
Perfume melts and pours out.But the pipe fitting section for bending out all can excessive deformation, design requirement can not be met.It is primarily due to tubing
Outside compression chord is smaller than center line both sides side in the effect that inner stuffing is stressed during bending, and tubing, and section stress is not
Make bending tubing section in like oval.If filler compression strength is not enough, pressed volume changes or occurs " flowing " phenomenon
Section is in like oval after bending will be made.When making filler using rosin, excessive compression makes rosin material occur in pipe
" flowing " phenomenon, makes to bow out the section deformation for coming.Meanwhile, the workplace irrigated using rosin is also very dirty and messy, the sky of work
Makings amount also very severe, is unfavorable for that staff's is healthy.Therefore urgent need develops one kind and can realize that thin-walled is small at present
The scheme of half diameter pipes bend pipe, to solve above-mentioned problem.
