elbow machine

The working principle of elbow machine: before the elbow machine begins to work, the tube billet is placed on the lower die, the inner core and end die are loaded into the tube billet, the upper die moves downward and begins to be pressed, and the elbow is formed by the constraint of the outer die and the supporting action of the inner die.The elbow after pressing is still a semi-finished product, which needs subsequent processing. For example, push the elbow while it is hot, use the press to suppress the defect of the fold without deformation, and use the bevel machine to slope to the Angle required by the customer.Sometimes also need to execute the shot blasting process, clean up the dirt, etc., good elbow of the process delicate to very detailed.Aocheng machinery equipment Co., Ltd. is committed to providing customers with better and better services and elbow machine series products.Elbow machine is non-standard product of pipe fitting equipment, it does not have specific specifications, models and sizes, can be customized according to customer requirements, to meet the needs of customers diversity.

The forming process of elbow pipe fittings often used includes cold push, hot push, stamping, extrusion, etc.Hot push elbow forming process: it is the working principle of using special elbow machine, using mandrel and heating device to make the steel tube and tube blank on the mold move forward under the push of the push rod, and be heated, expanded and bent during the movement.

Matters needing attention in carbon steel 1.5D elbow machine: the diameter of tube billet must be smaller than the diameter of elbow, otherwise it will affect the wall thickness requirement of forming elbow.The deformation characteristics of the reason is due to the hot pushing elbow is according to the volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter of elbow machine used by less than elbow diameter, through the core module and control the deformation of the process, make the inner arc of the compressed metal flow, compensation to other parts of the thinned by expanding, resulting in wall thickness of the elbow.
