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.
