A VACUUM FORMING APPARATUS FOR REFRIGERATOR

摘要

PURPOSE: A vacuum forming device for a refrigerator is provided to reduce the total thickness of sheets by uniformizing the thickness of each sheet and to save energy by improving thermal efficiency. CONSTITUTION: A vacuum forming device for a refrigerator is composed of a feeding station, a heating station(B), and a forming station. The heating station heats sheets(S) supplied from the feeding station. The forming station vacuum-forms the heated sheets. The heating station comprises a first fixing clamper(130) and a varying device. The length of the first fixing clamper is varied depending on the width of the sheets. Upper and lower cooling bars(131,132) of the first fixing clamper clamp the sheets in a width direction. The varying device varies the length of the lower coolng bar.
