Hebei elbow factory elbow to introduce what matters needing attention

Elbow is one of the pipe fittings, the purpose of the elbow is to connect the pipe into the pipe parts.According to the connection method, it can be divided into socket type pipe fittings, threaded pipe fittings, elbow pipe fittings and welded pipe fittings.

In the commonly used elbow specification model has been replaced by the hot push elbow, but in some specifications of the elbow because of less production, the wall thickness is too thin or too thick.

Elbow products have special requirements is the use of stamping production manufacturing process, in the stamping elbow forming process, the need to caliber and the production of good elbow caliber is the same, the use of press in the mold directly pressed molding.

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

However, due to the characteristics of unit production and low cost, the stamping elbow production and manufacturing process is suitable for the production and manufacturing of high-pressure thick wall stamping elbows in small batch production.

The extrusion elbow uses the special elbow forming machine to put the tube billet into the mold. After the upper and lower die is closed, the tube billet moves along the reserved gap between the inner die and the outer die under the push rod to complete the forming process.The elbow made by the cold extrusion process of internal and external die has beautiful appearance, uniform wall thickness and small size deviation. Therefore, the cold extrusion production and manufacturing process is suit
