The charging aperture of screw plate, the screw plate seaming are designed with the chamfering from 11 degree inside 20 millimeters of thread rolling edges of boards, are for machine
When product is sent to quiet filament plate mouth by bed feeding pincers, it is easy to product during thread rolling smoothly to enter screw plate.Set in pre-profiling anti-slip section 2
The anti-slip tank vertical with screw plate is equipped with, because product has just enter into screw plate, easily produces and skids and tilt, skidding is exactly thread rolling
Plate travels forward, and product is as screw plate moves, and anti-slip tank design is exactly to prevent product from skidding and tilting.
The determination of quiet filament plate size, because product diameter is big, pitch be even more up to 8 millimeters, formed product just can only gradually into
Type, product diameter is 30 millimeters, and to enable product smoothly to enter screw plate mouth, screw plate seaming, which designs, must allow product diameter mistake
Half enters screw plate, so seaming 1 is designed and sized to more than or equal to 20 millimeters；It is anti-after product enters screw plate seaming
Stop screw plate, which travels forward, makes product generation skidding cause product not as screw plate moves and rotate and tilt, in two thread rollings
Plate seaming rear end is designed with pre-profiling anti-slip section 2, but due to adding anti-slip section, power is cut in the stranding of equipment to be increased, so anti-skidding
