Bend manufacturer's attention requirements for production  

Elbow manufacturers are mainly engaged in the production of elbow pipe fittings, elbow is used to connect pipes into pipeline parts.  According to the connection method, it can be divided into socket pipe fittings, threaded pipe fittings, elbow pipe fittings and welded pipe fittings.  

In the commonly used elbow specifications and models have been replaced by the hot push elbow, but in some specifications and models because of the production quantity is less, the wall thickness is too thin or too thick.  

Elbow manufacturers have special requirements for products is only the use of stamping production manufacturing process, in the process of stamping elbow forming, the caliber of the need to be the same as the production of good elbow diameter, the use of press in the mold directly pressing molding.  

Stamping elbow is divided into cold stamping and hot stamping more stamping elbow material manufacturing technology, stamping elbow manufacture process than pushing elbow, elbow pipe quality and appearance is better than the former, stamping elbow outer arc in the tensile state during forming, no other parts redundant metal to compensate, so the outer arc of wall thickness thinning is about 10% or so.  

But because it is suitable for unit production and low cost, so the stamping elbow production and manufacturing process is suitable for the production and manufacturing of high pressure thick wall stamping elbow in small batch production.  

Extrusion elbow using commonly used elbow forming machine, the tube blank into the mold, up and down the mold, under the push rod, the tube blank along the inner mold and the outer mold reserved clearance movement and complete the forming process.  The elbow made of internal and external die cold extrusion process has beautiful appearance, uniform wall thickness and small size deviation, so the cold extrusion production and manufacturing process is suitable for the production and manufacturing of thin-wall stainless steel elbow, and the precision of the internal and external die used in this process is high;  The requirement of wall thickness deviation is also very strict.
