Abstract

The invention discloses a rotating shaft bending die adopting a floating lower die body. The problem that a part is excessively deformed or an upper die body is prone to being jammed due to the fact that the impact force of the upper die body is too large can be solved. The rotating shaft bending die comprises an upper die seat and the upper die body mounted on the lower portion of the upper die seat, wherein the upper die body can move up and down; a lower die seat is located under the upper die seat, a vertical mounting groove is formed in the upper portion of the lower die seat, and a pressure spring is arranged in the mounting groove. The lower end of the pressure spring is fixed to the bottom of the mounting groove, the upper end of the pressure spring extends out of the mounting groove, and the floating lower die body is arranged in the middle of the pressure spring; a circle of annular table is arranged on the periphery of the lower die body, the upper end of the pressure spring is fixed to the annular table, and the diameter of the annular table is larger than the aperture of the mounting groove; a convex column is arranged on the top of the lower die body, the upper portion of the convex column is a spherical surface, a stamping groove is formed in the bottom of the upper die body, and the stamping groove and the convex column are matched to bend parts.

Description

technical field [0001] The invention relates to the technical field of bending dies, in particular to a rotating shaft bending die. Background technique [0002] Bending is a stamping process that bends the blank into a certain angle through a mold and a press according to the shape of the part, and a workpiece of a certain shape. The bending forming process is widely used in automobile panels, motorcycle bracket components, foot bracket parts, pipes, sheets, etc. The existing bending dies often have the following disadvantages: when forming, the forming is completed by directly stamping the blank on the lower die through the upper die, usually the lower die is fixed, and sometimes the downward punching force of the upper die will be greater , and after reaching the stamping, it is easy to get stuck in rigid contact with the blank and the lower die, which not only causes excessive deformation of the parts, but also affects the molding quality, and the upper die is prone to ...
