Ingot blank after c will process is contained in the heating furnace and heats, and temperature is controlled at 280～350 ℃, is incubated 2～2.5 hours;
D is preheating to 220～270 ℃ to die sleeve, core rod, the backing plate of the backward extrusion counterdie of the backward extruding die device on the extrusion press, and is coated with lubricant at the die sleeve inner chamber;
E puts into the die sleeve inner chamber heating and through the ingot blank of insulation then, utilizes the extrusion press master cylinder pressure that the ingot blank backward extrusion is become the tube base;
F inserts the shaping inner chamber after again the tube base being heated to 280～350 ℃, utilize the superplastic deformation and the mould end gland pinch device of tube base itself that tube base mouth is pressed, make a base mouth sealing, when tube base temperature be controlled at 280～350 ℃ super when moulding in the temperature province, the high pressure nitrogen of progressive feeding 0～2MPa in the tube base, make base gas expansion forming in shaping die, pressurize 20～30 minutes obtains and the on all four groove drum blank of shaping die inner chamber shape face;
G removes groove drum blank both ends surplus by dimensional characteristic, finish and termination, processing technology hole, assembling two ends end cap;
The groove drum that assembles is carried out kinetic balance to h and guide detects;
I is to whole groove drum outside face hard chromium plating.
Tube base backward extruding die device is characterized in that this device comprises the die head that is packed on the extrusion press top shoe, be packed on the following table by interconnective backing plate, die sleeve and put into the backward extrusion counterdie that the core rod of die sleeve intracavity bottom is formed, heating jacket in backward extrusion counterdie periphery, be packed in four drag link sleeves of following table, in drag link sleeve, slide up and down with nut and be fixed on pull bar on the stripper plate, with pull bar top bonded assembly stripper plate, be enclosed within two ends on the pull bar and withstand on spring in stripper plate and the drag link sleeve respectively.
Owing to adopted technique scheme, the present invention compared with the prior art, that groove drum has is in light weight, intensity is reliable, conformability is strong, the guide formability is good, save the energy, characteristics such as the groove drum driving surface is wear-resisting, long service life, productive costs is low, the groove drum manufacturing process is simple, has guaranteed the requirements for quality of textile industry to groove drum.
