Description

Bending part A1 machining device

Technical Field

The utility model relates to the technical field of bending piece machining, in particular to the technical field of bending piece A1 machining and assembling.

Background

Bending refers to the process that metal plates are firstly elastically deformed and then enter plastic deformation under the pressure of an upper die or a lower die of a bending machine. In particular, as the upper die or the lower die presses the plate, the plate gradually approaches the inner surface of the V-shaped groove of the die, and simultaneously the curvature radius and the bending moment arm of the plate also gradually become smaller, and then continuing to press until the stroke of the bending machine is terminated, so that the upper die and the lower die are close to full contact with the plate at three points, and then completing the V-shaped bending. And the plate material adopting the processing technology is also called a bending piece.

The existing bending piece is usually required to be bent for multiple times, and the bending piece after multiple times is difficult to process again. People utilize frock clamp to fix the bending piece, and current frock clamp is the flat-nose pliers clamping generally, the theory of operation of flat-nose pliers clamping is for rotating the lead screw with the spanner, drive movable vice body through the lead screw nut and remove, so as to form the clamping and loosen to the work piece, but the fixed effect of flat-nose pliers clamping bending piece is relatively poor, especially when the bending piece is the dysmorphism piece, its clamping force that receives is inhomogeneous, make the bending piece easily drop, make bending piece easy clamping deformation, simultaneously, because the fixed unreliable of bending piece, the cutter phenomenon that shakes takes place easily during cutting or other processes, thereby cause the machining effect relatively poor, the lower problem of yield.
