Abstract
A wire condenser element bending method and a wire condenser element bending apparatus bend two wire condenser elements by pressing the wire condenser elements against a bending roller to form two scroll wire condensers simultaneously. Inner edge parts of the wire condenser elements are held by holding devices at diametrically opposite positions on the outer circumference of the bending roller. Pressure rollers press the two wire condenser elements against the bending roller while the bending roller is rotated to form two scroll wire condensers simultaneously. Each wire condenser element serves as a separator for separating layers of the other wire condenser element.
Claims17
A method of bending wire condenser elements around a bending roller to form scroll wire condensers, each wire condenser element being formed by bending a small-diameter metal tube in a plurality of parallel segments and connecting metal wires across the segments of the metal tube, each scroll wire condenser being individually usable and formed from a respective wire condenser element, said bending method comprising the steps of:
- holding inner edge parts of two or more wire condenser elements respectively by holding devices arranged at equal angular intervals on an outer circumference of the bending roller;
- winding the two or more wire condenser elements around the bending roller by pressing the wire condenser elements against the bending roller with pressure rollers while the bending roller is rotated so that respective layers of the wire condenser elements are superposed sequentially to form two or more scroll wire condensers, in which each wire condenser element serves as a separator for separating layers of the adjacent other wire condenser element or elements;
- removing the scroll wire condensers, formed by scrolling the two or more wire condenser elements, from the bending roller;
- and
- separating the two or more scroll wire condensers into individual scroll wire condensers.
A wire condenser element bending apparatus for bending a plurality of wire condenser elements around a bending roller to form a plurality of scroll wire condensers, each wire condenser element being formed by bending a small-diameter metal tube in a plurality of parallel segments and connecting metal wires across the segments of the metal tube, each scroll wire condenser being individually usable and formed from a respective wire condenser element, said bending apparatus comprising:
- a bending roller provided with holding devices arranged at equal angular intervals on its outer circumference to hold inner edge parts of the plurality of wire condenser elements detachably on the outer circumference of the bending roller;
- a driving unit for driving the roller in rotation;
- and
- pressing mechanism including pressure rollers for pressing the wire condenser elements against the bending roller to form two or more scroll wire condensers, in which each wire condenser element serves as a separator for separating layers of the adjacent other wire condenser element or elements and each of said two or more scroll wire condensers is individually separable as a finished product from each layer.
A method of bending wire condenser elements which are in a flat form and each comprises a small diameter metal tube bent successively in opposite directions to form parallel longitudinal segments connected at opposite ends by reverse U-shaped bends and crosswise wires connected to said parallel, longitudinal segments, said method comprising,
- holding one of the ends of a plurality of the wire condenser elements at equal angular intervals on an outer surface of a bending roller,
- applying pressure on each wire condenser element to press the wire condenser elements against he bending roller,
- rotating the roller to wind the wire condenser elements around the roller to form scroll condensers wherein the wire condenser elements are wound one adjacent another so that each wire condenser element serves as an intermediate spacer for an adjacent wire condenser element,
- removing the now bent wire condenser elements formed as scroll condensers from the roller, and
- separating the bent wire condenser elements from one another as respective scroll condensers.
