The present invention produces a curved article (10) having a hat-shaped cross section by means of press molding without generating cracks or wrinkles. When producing by means of press molding a curved article (10) having a roughly hat-shaped cross section comprising a top plate (11), vertical walls (12a, 12b) extending in parallel to each other along the ridge line (14a, 14b) of the top plate, and outward-facing flanges (13a, 13b) joined to the tips of the vertical walls, a starting material metal plate (601) is sandwiched and bound by a die (502) and a blank holder (505) and press molded while the starting material metal plate (601) is sandwiched and bound by a pad (503) and a punch (504).

The invention relates to a horizontal long-distance superfine powder pneumatic conveying device which is connected with previous-level feeding equipment and used for long-distance conveying of superfine power and toxic or corrosive materials. The horizontal long-distance superfine powder pneumatic conveying device comprises an air source machine, a working cabin, a material conveying pipe and a controller with a CPU (central processing unit), wherein the air source machine consists of an air storage tank, an air compressor and a fan, a material inlet is communicated with the working cabin andcontrolled by a first valve, one end of the material conveying pipe is communicated with the working cabin and controlled by a second control valve, the other end of the material conveying pipe is communicated with a separator, n segmental control valves are uniformly distributed on a horizontal section of the material conveying pipe, an air pipe with three branches is arranged on the air storagetank and is respectively communicated with the working cabin and a rotary sweeping and conveying device, the working cabin is communicated with the air storage tank and is controlled by a fourth valve, the rotary sweeping and conveying device is communicated with the air storage tank and controlled by a fifth valve, material is fed into the separator and discharged from a material outlet and the material outlet is controlled by a third valve. The horizontal long-distance superfine powder pneumatic conveying device is in a segmental suction type pneumatic conveying mode, the material is pressed segment by segment, and the conveying loss of the material is less than 20g.

The invention discloses a pipe bending device and a use method for the same and belongs to the technical field of pipe bending machines. The pipe bending device comprises a rack, a fixation base, a pipe material channel, a fixation part, a first bending wheel and a second bending wheel, wherein the fixation base is installed on the side face of the rack; the fixation base comprises a top cover anda bottom cover; the fixation part is located between the top cover and the bottom cover; the fixation part is used to fix a pipe material and the pipe material channel is a channel disposed in the fixation part; the first bending wheel is located at an exit of the pipe material channel, and the second bending wheel is located on the side remote from the rack and inclined to a material ejection mechanism; and the first bending wheel is used to bend the pipe material horizontally and the second bending wheel is used to bend the pipe material vertically. The pipe bending device disclosed by theinvention has the advantages that bending can be realized on an X axis and a Z axis simultaneously; and processing accuracy is increased. In addition, the invention discloses the use method for the device. The method has the advantages that operations are simple; reliability is high, etc.
