Title: Form straightening method for band-like material
Inventor: TATENOU KOUJI
IPC: B21D1/06
Filed: 1988-06-16
Abstract: PURPOSE:To straighten the form of a band-like material and to improve the forming accuracy of a product by allowing the band-like material to pass through a pressing and clamping machine in which a smooth receiving and supporting member and a rough polishing member are provided opposingly, bringing the band-lime material to press-contacting by limiting it to the overall width or the center part or only both sides, and adjusting the press-contacting force. CONSTITUTION:A veneer plate 19 is interposed on a substrate and a polishing member 21 of width of about 2/3 of the overall width of a band-like material 1 is brought to press- contacting limitedly to only the center part of the band-like material 1. In this regard, a receiving and supporting member 11 formed by winding round bleached cloth 9 to a veneer plate 10 is fixed to the lower face of a surface plate 18. Width of the polishing member 21 is changed suitably in accordance with a straightened shape, and sometimes the polishing member is used limitedly for only both side edge parts of the band-like material 1. In such a way, since the band-like material 1 is inserted and attached by a smooth receiving and supporting member and a rough polishing member and wound to a winding coil, as for the side where the band-like material is pressed against the polishing member, frictional force is remarkably higher than that of the side where it is pressed against the receiving and supporting member, therefore, a plastic deformation is generated in the band-like material 1 and the form is straightened. Also, by adjusting the press-contacting force, the degree of straightening can be changed easily, therefore, the form adjustment can be executed so as to meet a demand.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To inexpensively manufacture a contact type heat exchanger having a high heat transfer performance and a compact constitution by providing guide plates disposed in a propeller shape to guide a falling liquid around a shaft disposed toward a vertical direction in a container. SOLUTION: A liquid such as a cooling water or the like sequentially falling by forming a liquid film 12 from an oblique plate 31 of an upper stage to an oblique plate 31 of next stage falls according to an inclination of the plate 31 without stopping to freely drop between the upper and lower plates 31. A distance between the plates 31 is shortened to regulate a falling speed so as not to largely vary. A heat transfer between the falling liquid and the plate 31 has high heat transfer characteristics because of a stream and a thin liquid film, and a rear surface of the plate 31 having no liquid stream also becomes an effective heat exchange surface. Accordingly, a wasteful space is eliminated, and a size and a manufacturing cost can be reduced.
