The so-called “drum” is not fit to die, bulge phenomenon strip stainless steel arc tube.
Causes:
(1) the outer mould under pressure, no pressure in the end, the circular arc surface and on the surface of the horseshoe mold to strip out flat uplift.
(2) two track horseshoe cross, so that can not be completely pressed into the mould. It emerged in the arc bulge.
The solution:
(1) increase the pressing force of stainless steel pipe fittings.
(2) structure to shorten the length of the horseshoe, or shorten the length of the structure of central core, the horseshoe trajectory will not overlap.
The 6 outer arc “straighten” and disposal method. The so-called “straighten” refers to the two parts of straight section in flanking arc phenomenon.
Causes:
(1) the outer mould under pressure without pressure to mould and tightly, so in its two flanking office, pipe flat.
(2) because of the activity of cross path horseshoe, the pressure caused by the positioner can.
Disposal measures:
(1) increase the pressing force of stainless steel pipe fittings.
(2) structure to shorten the length of the horseshoe, or shorten the length of the structure of central core, the horseshoe trajectory will not overlap.
