摘要:
The purpose of the present invention is to provide a method for producing a pipe material and to provide a mandrel with which resistance between a member to be processed and the mandrel during bending processing can be reduced and overall processing time can be shortened. The method for producing a pipe material includes: a step for inserting a mandrel, which is provided on the inside thereof with a flow path through which dry ice powder flows and spray holes at the tip thereof for spraying the dry ice powder, inside pipe material; a step for spraying the dry ice powder from the spray holes inside the pipe material; and a step for performing bending processing on the pipe material wherein the mandrel has been inserted.

A mandrel support device includes a mandrel sleeve positionable on a mandrel to form a reservoir in fluid communication with a mandrel passage, and with. The sleeve may include a bore configured to receive a portion of the mandrel, a lubrication channel formed on the sleeve exterior, and a lubrication passage extending between the channel and the bore to permit fluid communication therebetween. A mandrel base may define a socket for interchangeably receiving the sleeve, and a lubrication bore may extend from the socket to the base to align with the lubrication channel when the sleeve is received in the socket. A fluid fitting mounted on the base in fluid communication with the lubrication bore and the lubrication channel of the sleeve such that fluid moving through the fluid fitting enters the bore, the channel and passage to reach the reservoir and mandrel passage at any rotational position of the sleeve with respect to the base.

A discharging furnace and a filling furnace are disposed in three dimensions in the upper and lower positions of a filling and discharging furnace. A reservoir is provided in an inclined surface protruding toward the lower filling furnace. The reservoir includes a valve operatively connected thereto. A hot blast heated by a duct heater through a duct is mainly fed into the discharging furnace for further heating, while a remaining small portion of the hot blast is fed into the filling furnace for keeping the filling furnace warm. Inside the discharging furnace, a filling material filled in a bent workpiece is molten and discharged into the reservoir and when the valve is opened, the gathered filling material is filled into the inside of the workpiece which is carried by a filling carrier. The filling carrier is divided into three portions of a filling pallet, a carrier body and a sealing pallet, wherein the filling pallet is provided with a nozzle and the sealing pallet is provided with a seal member. When the sealing pallet is moved upward, a slide deck is also moved up in a condition which the seal member is engaging with the lower end portion of the tubular workpiece, so that the tubular workpiece can engage at its top end portion with the nozzle. The filling material gathered within the filling pallet is then filled through the nozzle into the workpiece. In case the specification of the workpiece is changed, the nozzle and the seal member are replaced.
