Provided is a conveying apparatus for conveying a molded body for heat exchanger fins that can achieve high-speed conveyance of a molded body for heat exchanger fins, prevent generation of noise during conveyance, and have a smaller size. A solution is a conveying apparatus for conveying in a predetermined direction, a molded body for heat exchanger fins in a stage after a metal thin plate is provided with through-holes and before the metal thin plate is cut into a predetermined length in a conveying direction, the apparatus including: a rotary conveying body including a plurality of protrusions that are tapered and can enter the through-holes, and including a rotation shaft in a direction orthogonal to the conveying direction of the molded body for heat exchanger fins in a horizontal plane; and a rotary conveying body driving unit that rotates and drives the rotary conveying body, wherein a side surface shape of each of the protrusions is a shape to enable the protrusion to enter the through-hole with a space maintained in synchronization with a rotation of the rotation shaft, and retract from the through-hole while the protrusion conveys the molded body for heat exchanger fins in contact with the through-hole.

An apparatus for conveying a molded body for heat exchanger fins is capable of realizing high-speed conveying of the molded body for heat exchanger fins, of preventing the generation of noise during conveying, and of miniaturization. As a solution, an apparatus for conveying a molded body for heat exchanger fins has a plurality of conveying units, which each include a rotating conveyor driving unit and a rotating conveyor with a rotating shaft and rotating discs on which a plurality of protrusions that advance into the tube insertion portions of a heat exchanger fin are formed, disposed along a conveying direction of the metal strip, has a drive belt suspended between the rotating shafts of adjacent conveying units, and has an operation control unit that synchronizes rotational driving operations of the rotating shafts of the respective rotating conveyor driving units.

Provided is a method for conveying a separator that ensures stably conveying a separator material without leaving an indentation or the like. The conveyance method conveys a separator material for use in a single cell of a fuel cell. A hydrogen gas and an air are supplied for the fuel cell to generate electricity. The separator material has a rectangular shape in a plan view of the separator material, and the separator material has both sides on which a pair of through-holes are formed at proximity of a pair of hydrogen distribution ports through which a hydrogen gas flows. The conveyance method includes, when the separator material is conveyed, inserting a conveyance pin into each of the through-holes formed on the separator material, and in a state where the conveyance pin is inserted in each of the through-holes, conveying the separator material while pulling the separator material in a direction in which the conveyance pins mutually separate.

A pilot assembly and method for metal forming dies has a generally cylindrical pilot with a stripper that strips stock from the pilot when metal forming dies diverge. The pilot assembly is secured to one die member by a fastener by itself or in combination with a window mount. A spring within the pilot assembly contacts the stripper to force the stripper to reciprocate when the dies are pulled apart. Thus, the pilot assembly helps locate the stock within the metal forming die while also having a stripper to help strip the stock from the pilot.

A method for forming a thin, board-like base material has a tensile transfer step and a forming step. In the tensile transfer step, the long, thin, board-like base material is transferred by pulling the thin, board-like base material in the transfer direction while holding both ends of the thin, board-like base material along the transfer direction and pulling the ends outward in the direction intersecting the transfer direction. In the forming step, predetermined forming operations are performed with respect to the thin, board-like base material.

To enable high-speed conveying of a molded body for heat exchanger fins and, by conveying stably and with high precision, preventing deformation of the molded body for heat exchanger fins and the generation of noise when conveying the molded body for heat exchanger fins, a molding apparatus forms a plurality of cutaway portions at different positions on each molded body for heat exchanger fins of the product width. A conveying apparatus is provided with a rotational shaft that extends in the width direction and has a plurality of rotating discs that have a plurality of tapered protrusions, which are capable of advancing into the cutaway portions, formed on an outer circumferential surface thereof provided on the rotational shaft for each molded body for heat exchanger fins of the product width. When the plurality of cutaway portions of the molded bodies for heat exchanger fins of the product width, on which the plurality of cutaway portions have different positions, are disposed directly above the rotational shaft, the protrusions advance into the cutaway portions.

An automatic unloading, clamping and molding device for galvanized iron tubes and a manufacturing method thereof are used to position at least a crude pipe sleeve at a material strip and drive the crude pipe sleeve to pass through a positioning segment, a molding segment, a reshaping segment and unloading segment in a molding device for development of a plurality of graspable claw portions on the sleeve wall of the crude pipe sleeve and mass-production of stable-quality and low-manufacturing-cost pipe sleeves, each of which has a plurality of graspable claw portions.

A roll feeder is usable to convey a hoop material to a pressing machine. The roll feeder includes a paired first roll and second roll configured to be disposed so as to clamp the hoop material and feed the hoop material along a conveyance direction, a motor configured to drive at least one of the first roll and the second roll, and a controller configured to control drive of the motor. The controller includes a process drive instruction component configured to drive the motor so as to feed the hoop material to a pressing machine side in between one press working and next press working, and a working drive instruction component configured to drive the motor so as to feed the hoop material to the pressing machine side during press working.
