Groove is engaged goes out right-angle side by the equal roll-in in strip both sides；
Step 4：According to the width between the right-angle side of strip two, the intermediate projections of roller die on second are processed, in intermediate projections
On process recessed roll-in arc surface, while roller die on the second of intermediate projections both sides is processed into inclination rolling surface, according to
The corresponding rolling surface for processing second time roller die of the rolling surface shape of roller die on two；
Step 5：The right-angle side gone out according to the roll-in of strip both sides, it is corresponding to be processed in the 3rd left roller die and right-angle side phase
The roll-in rib of laminating, while the roll-in groove fitted with another right-angle side is processed in the 3rd right roller die, described roll-in
Rib makes right-angle side be fitted to the upper convex arc surface of strip with roll-in groove；
Step 6：According to the width between the right-angle side of strip two, pars intermedia is processed in roller die on the 4th, according to right-angle side
The position tilted after laminating strip, opens up the groove for depositing right-angle side on pars intermedia, is selected according to the width of pars intermedia
The width of the four times roller dies；
Step 7：According to the tube wall radian of shape tube, arch groove is processed in the five times roller dies, on the 5th in roller die
The roll-in termination being engaged with arch groove is processed, described roll-in termination is engaged with arch groove makes strip both sides right-angle side phase
To gather；
Step 8：According to the shape of shape tube, provided with two right-angle sides of polymerization in roller die on the 6th of the 6th rolling die group
Roll-in projection, in the six times roller dies of the 6th rolling die group be provided be used for polymerize two right-angle sides roll-in deep-slotted chip breaker,
Described roll-in projection is engaged with roll-in deep-slotted chip breaker for the strip gathered roll press to be surrounded with apertured shape tube；
Step 9：The shape tube shape needed according to client, provided with sizing in roller die on the 7th of the 7th rolling die group
Projection, provided with sizing deep-slotted chip breaker in the seven times roller dies of the 7th rolling die group, described sizing projection and sizing arc
Groove is engaged for by the sizing of the shape tube of non-soldering, being easy to the welding gun of peripheral hardware by gap soldering.
