Production of 90 degree bending radius 1.5 carbon steel cold push
pipe bender
1. Product Presentation
The forming process of cold extrusion elbow is to use the special
elbow forming machine to put the tube blank into the outer die, and
after the upper and lower die are combined, the tube blank will
complete the forming process along the clearance activities
reserved for the inner die and the outer die under the push of the
push rod.The forming process of cold extrusion elbow is to use a
special bending forming machine to put the tube blank into the
outer die. After the upper and lower die are combined, the tube
blank will complete the forming process along the clearance
activities reserved for the inner die and the outer die under the
push of the push rod.It is by an ox horn shape core head or mandrel
into the mold, will put the pipe into the mold, the mold should
have two semicircle, one up and one down, in the process of pushing
is a process along the mandrel bending.With support in the back,
the cutting tube section is inserted into the mandrel, and there is
a bracket in the back to make the mandrel firm.There is a hydraulic
ejector in the center, which is pushed forward by the hydraulic
driving ejector.Push the tube along the mould semicircle groove
along the mandrel until the top column reaches the end position,
the limit switch lock dies, and then push the tube down to finish
one.The outside diameter after shaping reached the size
requirements of the product.The wall thickness is controlled by the
wall thickness of the incoming material.In the process of pushing,
the wall thickness under normal environment should not be changed,
but if due to the cause of things, some places will produce the
sign of reducing the wall, in order to be the same as the usual
material, the wall thickness to add some margin, to prevent in the
push system due to local reduction of thickness and out of
tolerance.The outside diameter and wall thickness of the elbow have
reached the requirements.The following will be a fine process, from
the treatment of shot-peening penalty, the elbow of the inner and
outer surface of the iron oxide removal, the two sides of the
groove treatment to facilitate welding.After checking again at the
end, make steel word, spray paint, pack wait for working procedure,
can put in storage, leave the factory next.
Adopt inside and outside die cold extruding craft the elbow shape
is elegant, the wall thickness is symmetrical, the size defect is
small, therefore deal with stainless steel elbow especially outside
is thin - walled stainless steel elbow shape more accept this craft
manufacture.The accuracy of internal and external die used in this
process is high;The wall thickness of the billet is also more
demanding than the force.
