| The working principle of elbow pushing machine for elbow forming
Elbow push machine is mainly formed according to the metal material plastic deformation of the constant volume of the design, the volume of pipe billet is equal to the volume of the elbow.The main working principle of elbow pushing machine is: the tube billet is set on the mandrel in turn, and then start the extrusion propulsion device, the tube billet is pushed into the mandrel in turn, the front end of the tube billet is sent to the beginning of the mandrel in turn, and the forming process begins.As the mandrel is pushed along the axis of the bending mandrel to the outlet end, the diameter expansion is gradually realized in the bending deformation.When the tail of the billet breaks away from the end face of the push mandrel outlet, the forming of the whole elbow has been completed.In the process of elbow pushing, with the increase of diameter expansion, the thrust force makes the tube blank not thinner in comparison, and the thickness of the inner and outer arc walls is basically the same.The above briefly introduces the forming principle of elbow push-making machine.
A simple drawing of elbow pushing machine: elbow pushing machine, induction coil, insulation device, mandrel, extrusion device, clamping device, extension rod, pipe blank, carrier device, transmission device, etc.Elbow push machine simple operation, high production efficiency, low noise welcome new and old customers.The elbow pushing machine is used for the forming of the elbow, the main power is the hydraulic cylinder, the heating method is medium frequency heating (in addition to the use of coal stove and natural gas heating) the diameter of the elbow from 21mm to 1620mm, the wall thickness from 3mm to 120mm,Medium frequency heating type elbow machine is mainly used for carbon steel and alloy steel elbow forming, if the product you need is stainless steel elbow, please choose the cold push elbow machine produced by our company.
The intermediate frequency heating elbow machine mainly includes: the main engine, the main cylinder support plate (including the main cylinder), the movable push plate, the front support plate, the semi-automatic feeding mechanism, the intermediate frequency coil adjustment frame (including the intermediate frequency heating coil), the intermediate frequency power supply, the electrical control system and so on.
Technical parameters of medium frequency elbow machine:
2704-2706.
