The length of the aluminum tube is about 180mm, the diameter is 19mm, and the wall thickness is about 1mm. It should be bent into the radian of R300. No deformation
Provide two ways for youThe 1. is what they say is to fill in the sand, the deformation rate should be within 5%, but the efficiency is slow2. is a new type of mandrel bending machine, direct cold bending, deformation rate of 5%, high efficiencyPS: do not use mandrel bending machine, because the mandrel and tube friction, tube wall will be thinned, roundness will be very serious deformation (because your pipe wall thin because), if the tube through objects or liquid, will form dirt
Pouring sand into the aluminum tube, the two ends are blocked and then the bend will not deformWith lead? Where do you go for lead?
The mandrel with a diameter smaller than the inner diameter of the aluminum pipe is made into two sections, and the aluminum pipe is inserted from both ends (contact at both ends), and the mandrel can be pulled out when bent into the required radian. A mandrel can be made of material that is softer than aluminum, such as lead.
