Brief introduction of U-shaped part bending die in stamping parts processing plant

The U-shaped part bending die in the stamping parts processing plant is shown in the figure. Figure a shows the bending die of a general U-shaped part in a stamping part processing plant. The blank is pressed by the blank during bending, and the workpiece is lifted after bending. If the workpiece is stuck on the punch, it will be pushed down by the push rod. . Figure b shows a closed-angle bending die, which is used to bend U-shaped parts with an included angle of less than 90°. When bending, the punch first bends the blank into a U shape. When the punch continues to press, the punch and the movable concave The molds are in contact with each other and the left and right movable dies are rotated around the center, and finally the blank is formed by bending. When the convex mold rises, the spring resets the movable concave mold, and the workpiece is removed from the direction perpendicular to the drawing. Recommended article: The calculation principle of the edge size of the convex and concave die is reflected in the stamping die.
