Elbow is a kind of pipe fitting used for pipe turning. It accounts for more than 80% of all pipe fittings used in pipe system and is a very important pipe fitting.So the use of elbow forming machine demand in the market is also short supply.
Constitution of bend forming machine equipment: have alloy core head, intermediate frequency coil bracket, intermediate frequency coil, export support, pushed the door open, hydraulic cylinder, after pushing plate, gate, hydraulic lift cylinder, the main oil cylinder, cylinder bracket, after feeding the core rod, the big chassis, oil cylinder, motor, axial plunger pump, manifold blocks the (install the above and other components of the hydraulic control valve), adopts hydraulic automatic feeding mechanism
The gate of elbow forming machine adopts hydraulic opening and closing, according to the equipment needs to use two or four oil cylinders push system, the equipment runs more smoothly.
Intermediate frequency elbow machine
The forming of heat push medium frequency elbow machine
is designed according to the law that the volume of metal material is invariable when plastic deformation occurs, that is, the volume of tube blank is equal to the volume of elbow.Several tube billets were placed on the mandrel in turn, and then the extrusion propulsion device was started to push the tube billets successively, such as the push mandrel. The front end of the tube billet was sent to the start of the push mandrel, and then the deformation process began.With the push along the axis of the push mandrel toward the exit, the expansion and bending deformation are gradually realized. When the end of the tube billet is removed from the exit face of the push mandrel, the forming of the whole elbow is completed.In the process of pushing and bending, with the increase of diameter expansion, the thrust force makes the tube billet continuously perform radial compensation. Therefore, the wall thickness of the finished elbow is not thinner than that of the tube billet, and the wall thickness of the inner and outer arc is basically the same.Heating medium frequency elbow machine is mainly used for bending carbon steel and alloy steel. If you need stainless steel elbow, please choose cold push elbow machine.
