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 pushing machine is a device for pushing elbow.It is mainly designed to solve the problem of large wall thickness difference of pressing elbow.It includes frame, intermediate frequency heater, hydraulic system, with fixed bed fixed to the frame of the back-end, fixed with a hole at the center of the machine, the oil cylinder is fixed on the fixed table, no bar and rod of oil cylinder cavity respectively through the pipe connected to the hydraulic system, have a haircut and the oil cylinder cylinder rod fixed contact, with a hole have a haircut, intermediate frequency heater with heating coil wire connection,Wedge key hole is at the back of the core rod from heating circle and have a haircut in the hole and the center of the fixed bed hole through the wedge key to wear in the key hole wedge core rod, activity semicircle card board is composed of upper and lower two semicircle card board, card board activity half of upper and lower two semicircle card board are installed on the surface before have a haircut at the same time set on the mandrel and with core rod gaps.The advantage is that the produced elbow wall thickness is uniform.

Elbow pushing machine itself belongs to non-standard products, so there is no specific specifications and models. We can directly customize according to customer requirements. Elbow pushing machine can push elbow diameter from 21mm-1620mm, wall thickness from 3mm-120mm and above these models.Elbow push machine simple operation, high production efficiency, low noise welcome new and old customers.
