An elbow is a type of pipe used for turning a pipe. Among all the pipe fittings used in the pipeline system, the proportion is the largest, about 80%. Generally, a different forming process is selected for the elbows of different materials or wall thicknesses. At present, the seamless elbow forming process commonly used in manufacturing plants has hot push, stamping, extrusion and the like. Divided into Hot Elbow Machine Price and cold push elbow machine.
Now we are important to accept the cold extrusion elbow forming method. The forming process of the cold extrusion elbow is to use a special elbow forming machine to put the tube blank into the outer mold. After the upper and lower molds are closed, the blank is reserved along the inner and outer molds under the push of the push rod. The gap is active to complete the forming process. The principle of pushing the elbow by cold extrusion is very simple. The forming process of the Cold Forming Elbow Machine Price is to use a special elbow forming machine to put the tube blank into the outer mold, and the upper and lower molds are clamped and pushed by the push rod. The tube blank is moved along the gap reserved by the inner mold and the outer mold to complete the forming process. It is placed in a mold by a horn-shaped core or mandrel. The tube is placed in the mold. The mold has two semi-circular arcs, one on each side, and the process of bending is a process of bending along the mandrel. There is support behind, the cutting pipe section is inserted into the mandrel, and there is a brand of truss behind to secure the mandrel.
