摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a method for manufacturing a flat tube, by which setting up time is reduced and complication of equipment is suppressed and by which factors for forming defects such as buckling of materials are eliminated.
SOLUTION: In the method for manufacturing a flat tube T by bending a belt-like material M to be worked, a preliminary machining groove Md is formed by bending the material M to be worked in advance along the center axis in the longitudinal direction. Then, while the material M to be worked is gradually moved, both longitudinal side edges of the material M to be worked are slowly brought close to each other, with the preliminary machining groove Md as the center, and bent to form a tubular shape.

摘要： PROBLEM TO BE SOLVED: To exactly form a complicated or largely deformed portion on a material to be formed.
SOLUTION: In a press forming apparatus, respective rollers of a plurality of first group rollers and respective rollers of a plurality of second group rollers are alternately arranged in the longitudinal direction of the material to be formed. In the first stage, the respective rollers are turned at the ordinary rotational speed corresponding to the speed of the material to be formed moving in the longitudinal direction, and the forming portions of the respective rollers form deformed portions on the material to be formed. In the second stage, with respect to the respective rollers, the positions of the deformed portions of the material to be formed are detected, wherein the deformed portions are formed by the roller located on the just upstream side in the same group as that roller, and then, the modified rotational speed of the respective rollers necessary for matching the forming portions of the respective rollers with the deformed portions of the material to be formed is calculated based on the detected positional information, and the respective rollers are turned at the modified rotational speed without bringing the forming portions of the rollers into contact with the deformed portion formed by the roller located on just upstream side in the different group. In the third stage, the deformed portions of the material to be formed are furthermore deformed by the forming portions of the respective rollers by turning the respective rollers at the ordinary rotational speed. The second stage and the third stage are repeated.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for changing the pitch of an off-set shape fin, by which method and apparatus, the pitch of a wide off-set shape fin can be surely shortened or enlarged to a required pitch, and also the scatter of the pitch of the fin for one tooth can be suppressed as small as possible. SOLUTION: In the method and the apparatus for changing the pitch of the off-set shape fin, the off-set shape fin is supplied between pitch changing rollers, which have teeth formed on their outer peripheries and are rotated by meshing with each other, and the pitch of the off-set shape fin is changed by gripping and moving the off-set shape fin between the pitch changing rollers. The respective teeth shapes of the pitch changing rollers are almost the same as the profiles of the respective rollers in the cross section in the advancing direction of the off-set shape fin after changing the pitch by means of the pitch changing rollers.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a corrugated sheet, capable of improving production efficiency and restraining enlargement on the length of the whole processes.SOLUTION: A connection section forming means of an apparatus 30 for manufacturing a corrugated sheet forms a connection section 13 at one location in a width direction of a strip-like sheet 15 per a designated each interval in a feed direction. A corrugated sheet forming means bends a flat plate section 21 located between the connection sections 13 of the strip-like sheet 15, and forms a corrugated sheet section 11 having a plurality of projected sections 12 extended in the feed direction and lined up in the width direction. A cutting means cuts the connection section 13 of the strip-like sheet 15 per the number of connections established by a setting means. Consequently, various kinds of inner fins having different lengths of the projected sections 12 are made by changing the number of connections of the connection section 13 without exchanging the strip-like sheet 15 wound at a coil shape. Further, the corrugated sheet forming means is arranged on one location only in the feed direction since the front and rear flat plate sections 21 in the feed direction do not limit mutual movements in the width direction except one location in the width direction.
