SEMI-AUTOMATIC MACHINE FOR BENDING OF WIRE ITEMS Russian patent published in 2011 - IPC B21F1/00 B21F45/00 

FIELD: metallurgy.

SUBSTANCE: semi-automatic machine includes base on which two opposite located bending modules are located. The above modules include pneumatic turning device and hollow shafts with driven gears fixed on them and engaged with driving gears of drive shafts of pneumatic turning devices, and pushers installed in hollow shafts and connected to pneumatic cylinders of their back-and-forth movement, bending mechanisms and workpiece pressure mechanism. Semi-automatic machine is equipped with composite template the profile of which is equivalent to the profile of the item; central part is mounted on one of bending modules with possibility of vertical and horizontal adjustments, and side parts are fixed on ends of pushers, which are opposite to the above pneumatic cylinders; at that, one of the bending modules is installed so that its movement can be adjusted in order to change the centre-to-centre distance between axes of bending modules; bending mechanisms are mounted on bending modules and made in the form of face-plates fixed on the above driven gears, guides, sliding members, which are connected to pneumatic cylinders of their movement, and bending rollers mounted on sliding members.

EFFECT: enlarging manufacturing capabilities and the range of produced items.
