Product Description

THG406 CNC roller hot spinning machine is based on our company's years of rich experience in manufacturing thermal cyclone, combined with foreign advanced equipment technology, the original technology for a number of technical improvement and developed.


The equipment is mainly used for the formation of high pressure gas cylinder, through the equipment to the pipe at both ends of the bottom, so that the pipe end into a standard spherical, ellipsoidal shape and a simple section of straight line and arc, made into the shoulder section of equal thickness and non-equal thickness high pressure cylinder.

It is mainly composed of conveying mechanism, medium frequency heating system, feeding device, spindle mechanism, rotary mold device, turning device, automatic heating device, feeding device and discharge thrust head, hydraulic system, electrical system, dilute oil lubrication system, etc

Medium frequency heating system

The intermediate frequency heating system mainly heated the rotary part of the end of the pipe to the forging temperature (less than 1250ºC) to facilitate the metal flow and plastic deformation. The working principle of medium-frequency heating system is one of the practical applications of electromagnetic induction law.The system uses the induction coil as a primary coil and the steel pipe in the furnace as a secondary coil.When the induction coil on the alternating magnetic flux, most of the flux chain with the steel pipe in the furnace, so the induction potential in the steel pipe, and because the steel pipe is a conductor and closed circuit, under the action of the induction current I, and due to the current surface effect and steel pipe resistance R, so produce a large number of joule heat, so that the furnace heating. The medium frequency heating system is mainly composed of heating furnace body and medium frequency power supply cabinet.
