摘要： PROBLEM TO BE SOLVED: To easily bend a sandwich panel without buckling a core material or a skin material.SOLUTION: The sandwich panel P is configured to join a metal core material 11 having many openings 11a interposed between the two metal skin materials 12 by brazing or bonding. The sandwich panel P is bent by a press die 15 while initial tensile force Fp is applied to the skin material 12, so that even if compressive force Fc is applied to the skin material 12 at the inside in a bending direction, the compressive force Fc is canceled by the initial tensile force Fp to prevent buckling from being generated at the skin material 12, and accordingly the sandwich panel P is easily bent without buckling the core material 11.

摘要： PROBLEM TO BE SOLVED: To provide a servo mechanism for a clamping device of a rapid and correct stretching machine. SOLUTION: In a stretching machine 10 in which curved clamping devices 24, 25 opposite to each other clamp both ends of a metallic sheet, the clamping devices 24, 25 are grippers which are relatively moved by a hydraulic cylinder and arranged adjacent to each other, the stretching machine 10 includes a closed loop type servo control means, moves each gripper to a specified position, includes a hydraulic cylinder position controller of the hydraulic cylinder of each gripper, and controls the hydraulic cylinder based on the stored data to indicate the specified position for the gripper. The position controller is driven by a motor, a hydraulic cylinder position feedback means is provided on the hydraulic cylinder, and the signal to indicate the position of the cylinder is transmitted to the position controller.

摘要： PROBLEM TO BE SOLVED: To reduce a deviation from a desired dimension by inserting polymer mandrels from both sides of a hollow metal body and bending while stretching the hollow metal body from both ends in the longitudinal direction to prevent collapse of the hollow metal body due to bending. SOLUTION: A hollow extruded work 20 is mounted between gripper assemblies 11, 12, mandrels 35, 36 of a solid polymer mandrel are pressed/inserted thereinto from opening ends 37, 38 of the extruded work 20 by using piston rods 31, 33. At this time, a lubricant is supplied by a fiber core adjacent to an outer wall 40 through opening parts of guides 25, 26. Jaws 13, 14 are fastened. The extruded work 20 is bent while stretching by hydraulic cylinder assemblies 27, 28 on guides 25, 26 in the longitudinal direction. Successively, the extruded work 20 is again stretched to remove residual stress. The jaws 13, 14 are released from the end parts 21, 22 of the extruded work 20, the mandrels 35, 36 are mechanically removed.

摘要： PURPOSE:To form a sirocco fan having the total length of cross section of a blade longer than pitch of the blades by forming parallel grooves in side direction having the prescribed pitch in longitudinal direction of raw material, shearing at bottom parts of the grooves and forming the blades having the desired shape after executing two forming processes to bending sheared pieces, where one side is bent in the groove and the other side is as it is. CONSTITUTION:On the strip shaped raw material having calking pieces 4 of the fixed pitch at both side edges, the U shape grooves 2 of the pitch P are formed and sheared at almost center of the bottom thereof, and the one side is made to the bending piece 2a and the other side is as it is 2b. From the 2a and 2b parts, the blades 3 having the desired shape are formed with the two processes to obtain the blades 3 having the length L of cross section longer than the pitch P. Successively, the worked material W having the blades 3 is rolled up to make cylindrical body, and the calking pieces 4 are inserted into inserting holes arranged in circular direction of round shape side plates 5a, 5b. By this method, the sirocco fan having less number of parts and easy to assemble can be obtd.
