Abstract

The invention discloses a creasing-free stamping die for manufacturing U-shaped stainless steel plates. The die is provided with an upper die and a lower die which are opposite to each other. A cavity is formed in the lower die, a mounting hole is formed in the bottom, located in the lower die, of the cavity, a piece jacking device stretching into the cavity is arranged in the mounting hole, and adjustable positioning plates are arranged on the left side and the right side of the top of the lower die. The creasing-free stamping die is characterized in that semicircular grooves are formed in the top of the left side wall and the top of the right side wall of the cavity, rolling rods are arranged in the semicircular grooves in a rolling mode, and the inner side faces of the two rolling rods are flush with the left side wall and the right side wall of the cavity. The creasing-free stamping die is mainly used for bending and forming of the U-shaped stainless steel plates, the plates manufactured through stamping are free of creasing, and the surface quality of the manufactured plates is improved greatly.

Description

technical field [0001] The invention relates to the technical field of sheet metal molds, in particular to a stamping mold without indentation for producing U-shaped stainless steel plates. Background technique [0002] At present, U-shaped stainless steel plates are usually produced by stamping dies. The traditional stamping dies for producing U-shaped stainless steel plates include upper and lower dies arranged oppositely. A cavity is provided in the lower die, and the bottom of the cavity is located There is a mounting hole inside, and a top piece extending into the cavity is installed in the mounting hole, and adjustable positioning plates are installed on the left and right sides of the top of the lower mold. This kind of traditional stamping die generally designs the top of the left and right side walls of the cavity as right angles or rounded corners. When the stamping die bends the blank into a U-shaped plate, the blank will be bent and deformed, and the bottom of th...
