The invention discloses a
quartz thick-walled tube secondary
moulding device. The
quartz thick-walled tube secondary
moulding device comprises a furnace body and a traction mechanism; the furnace bodycomprises a furnace shell, an upper end cover, a lower bottom plate, an
induction heating coil, an upper
induction heating member, a center pole, a lower
thermal insulation member, and a moulding platform; a furnace chamber penetrating the furnace body is arranged in the furnace shell; the upper end cover and the lower bottom plate are arranged on the upper end and the lower end of the furnace shell respectively; the upper end cover is provided with a locating groove and a
nitrogen gas hole; the lower bottom plate is provided with a feeding port and a
nitrogen gas hole; the induction heatingcoil is arranged in the furnace shell; the upper
induction heating member is a hollow cylindrical structure member, is arranged in the furnace chamber, and is suspended on the upper wall of the furnace shell; the center pole is arranged in the furnace chamber, and is located using the locating groove, and is provided with a through hole; the lower end of the upper induction heating member is connected with the moulding platform; the moulding platform is provided with a tapered
throat; the lower end of the moulding platform is provided with the lower
thermal insulation member. The invention also discloses a secondary moulding method using the
quartz thick-walled tube secondary
moulding device. The quartz thick-walled tube secondary moulding device is capable of realizing a second time of moulding of thick-walled tubes with a thickness higher than a tolerance, and saving raw materials effectively.
