90 degree ERW welded stainless elbow cold pushing making machine
1.Product Presentation
What factors will affect the shape of the elbow shaped by the pushing process of the bending machine?Through the research of the relevant staff, the influence of billet, mandrel,temperature and advance rate on the curvature radius of the elbow, and the influence of section irroundness on the wall thickness was studied, and the following conclusions were drawn:D/Dp (elbow cross section diameter/blank outside diameter) = 1.33 ~ 1.40;B /a (long axis of mandrel ellipse section/short axis of mandrel ellipse section) = 1.06 ~ 1.10;The highest heating temperature of WB36 material = 880 ~ 900℃, the highest heating temperature of A335 P22 material = 900 ~ 920℃;Thrust rate ≤1000 /2D (-- elbow wall thickness, D -- elbow section diameter).The important parameters of the shape of the cold-push elbow machine include curvature radius R, section irroundness perpendicular to the curvature radius circle and wall thickness.The process parameters that affect the shape of the elbow have the following aspects: billet material, wall thickness and outside diameter, mandrel head material and shape, heating temperature and diffusion, and advance rate.
What are the differences between cold elbow press and hot elbow press?Cold push elbow machine is also known as stainless steel elbow machine, in the past, stainless steel, alloy steel elbow to provide emergency, its appearance is to satisfy the production of stainless steel, alloy steel elbow necessary development, but also to satisfy the special requirements of carbon steel elbow production.
Cold push elbow machine and hot push elbow machine are not the same. In addition, cold push elbow machine does not need to accept intermediate frequency coil heating, thus saving energy and environmental protection.Push the bending time, to cut the tube blank sawed down, the shape of the cutting tube blank is trapezoidal, but the hot push elbow machine and cold push elbow machine is different, in addition, the hot push elbow machine cutting tube blank is rectangular.
