Glass gob shearing apparatus and method with internally cooled and contact lubricated blades
摘要:
A parallel shear apparatus (20) for simultaneously shearing a plurality of streams of molten glass (A, B, c) into gobs comprising opposed carriages (22, 24) which are repetitively moved along rectilinear opposed paths toward and away from one another by a unidirectionally acting servo motor/gear reducer (44) acting through an oscillating bell crank (30). Each of the carriages carries a plurality of shear blades (40a, 40b, 40c/42a, 42b, 42c) which cooperate with one another to shear the glass streams into gobs when the carriages are positioned close to one another. The shear blades carried by each of the carriages have internal flow passages (66) to permit the blades to be internally liquid cooled by liquid entering the carriages from inlet lines (52, 56), and the blades carried by one of the carriages (22) are biased by compression springs (82) into contact with the blades carried by the other carriage (24) to prevent excessive contact loads between the blades in their shearing positions. A contact lubricator (88) is provided to lubricate the contact surfaces of the blades carried by one of the carriages (22).
