Mandrel type elbow machine

Manufacture process of mandle-type elbow: this process is suitable for the manufacture of carbon steel butt-welding long radius and short radius elbow made by hot push.

Cold push elbow machine is mainly characterized by low cost, but low efficiency, the need for more artificial.

The main characteristics of cold push elbow machine is high cost, but also high efficiency, and save manpower.

Cold push elbow machine itself belongs to non-standard products, so there is no specific specifications and models, we can directly customize according to customer requirements.

The mandrel type elbow machine from the bottom to the finished product process matters needing attention: adjust the center height of the mandrel.And keep consistent with the push head center of the push machine.Adjust the front and back travel limit of the push machine.Adjust the working pressure and advance speed of the push machine.Check whether the hydraulic, electrical and cooling systems work normally and whether the action is sensitive.For lubrication, the inner wall of the pipe is coated with a thin and uniform layer of graphite powder.Start the pump, intermediate frequency power supply, adjustment of intermediate frequency power, and match the advancing speed, push the machine before the mandrel rod fixture on the tube billet slowly forward, tube billet by induction heating ring, the pipe under the action of thrust and under high temperature condition began expanding, bending forming and take off the plug, to complete a bending forming process.
