The invention provides a small-
diameter cylinder automatic forming device and process. The device comprises a
machine base, clamping bases, fixing bases, a guide rail, a clamping arm, a hydraulic
system and cooling systems, wherein the clamping arm is composed of a left clamping arm and a right clamping arm, the left clamping arm and the right clamping arm are symmetrical left and right, and are the same in structure, a hydraulic clamping mechanism is arranged in each clamping base, an F-shaped safety clamping jaw is arranged at the front end of the clamping arm, the
tail part of the clampingjaw is connected with an air cylinder
piston rod, a left clamping arm fixing base is installed on the
machine base, a right clamping arm fixing base is installed on the guide rail, a stepping motor isarranged on the guide rail, the motor drives the guide rail, and the
tail ends of the fixing bases are provided with gears,
servo motors and cooling systems. A
rounding process comprises the following steps of preparation, feeding, detection, clamping,
rounding and the like. According to the small-
diameter cylinder automatic forming device and process, the problems of bending and
welding on original small size, small angle and small
radius sector-shaped plate materials with diameters of the small ends are larger than 46 mm after being bent into a cylinder body are solved, the production costis reduced, the problem that the requirements of original pure manual operation on technology of operators are high is solved, so that the quality and the efficiency of products are improved.
