Calculation process of blanking formula of seamles

Calculation process of blanking formula of seamless elbow pipe fittings  

Seamless elbow is the simplest way to calculate the formula, seamless elbow is divided into push long radius elbow and short radius elbow.  The shape of the seamless elbow is torus, which is a non-developing surface. In the actual configuration design, in order to facilitate the development of processing, we had to change to the method of segmenting, and change the torus to cylinder.  

Seamless elbow feeding formula: 90°R=1.5DN Push elbow feeding length (mm) = elbow outer diameter (mm) *1.5*1.57* elbow outer diameter (mm)/pre-selected steel pipe outer diameter (mm) + pre-selected steel pipe wall thickness (mm) *3 This formula also needs to refer to the manufacturer's core bar size.  

Seamless elbow shall be divided into T sections for cutting, and the value of T shall be input with the actual number of sections. When calculating, both ends shall be calculated according to half section, and the middle shall be calculated according to one section, that is, the turning Angle of each section is A /(T-1).  T must be an integer, 3<=t<=30, the larger the value of t, the smoother the elbow, but the workload and cost increase, generally take 15<= A /(t-1)<=25.  

The above is the blanking process of seamless elbow pipe fittings introduced by our company for customers.
