Weighs less than 50 lbs.Ĭomes complete with everything you see in the above picture(minus tubing in bender)Īdditional Die Sets available 1" on 5" Radius, 1-1/4" on 5" radius, 1-1/2" on 7" radius, 1-5/8" on 7" radius and 1-3/4" on 7" radius. 095 DOM or Chrome moly round tubing Not recommended for thin wall muffler tubing. 134 HREW/ERW Wall mild steel round tubing and. (Die and Mandrel have 1" shafts for durability and longevity) Bends. Simply bend a 90, slip the tube through the die and bend up to an additional 20 degrees totaling 110 degrees of bend. 8 Ton Hydraulic Jack Bends 1-3/4" Round Tubing Only(Includes 1-3/4" on 7" radius die set only) Additional Die Sets available that work on this bender. HYDRAULIC TUBING BENDER FEATURES: Our all new design. Should any of the changes above solve the cracking issue, but introduce other problems, you should fault find these issues separately.Affordable Bender - 1-3/4" Die on 7" Radius These changes will help to push material into the bend, and reduce the stress on the outside of the bend. If the above are not successful, it might be that the amount of pressure die assist should be increased, or on some machines it may be possible to boost/push the end of the tube. It can also be the case that the tube is being squeezed too hard by the pressure die, preventing material from flowing, this may need backing off a little. You should also ensure the mandrel is not positioned too far forwards, as the tube cannot bend around the mandrel body if positioned incorrectly, and this can cause breakage. We recommend ensuring a heavy drawing lubricant is used on the mandrel to prevent metal on metal resistance. The solution is simply to prevent the outside of the tube from stretching beyond its limit. Materials that are particularly hard tend to exhibit brittle failure, whereas grades of mild steel or the 300 series stainless steels tend to bend more easily, but could be prone to ductile breakage in certain situations. The edges of a brittle failure can appear clean and shiny. This is often quite abrupt, with little signs of the tube stretching. Secondly, a brittle failure can be seen if the tube appears to have simply snapped. It’s important to note here that there are two distinctly different types of breakage.įirstly, a ductile material failure, this is seen where the tube has visibly stretched and thinned before eventually reaching breaking point. Sometimes it seems like a tube simply won’t bend, and instead has a tendency to simply crack or rip. Tube is splitting/cracking on outside of bend radius
