Bending springback intelligent compensation device, continuous die and bending springback compensation method

Abstract

The invention discloses a bending springback compensation device, a progressive die and a bending springback compensation method. The device is provided with a detection mechanism (3), a shaping mechanism (4) and a controlling system. When in operation, the springback amount of bent punching piece (1) is detected by the detecting mechanism (3), corresponding compensation amount is obtained according to the detecting result of the detecting mechanism (3), so that the stretching and retracting amount of a shaping inlet block (43) is adjusted by controlling an adjusting assembly (5) in the shaping mechanism (4), and therefore the intelligent compensation effect is achieved. The device has the advantages that the bent punching piece can be automatically detected, and targeted shaping is conducted by the shaping mechanism to greatly improve the quality of products, automation level and production efficiency.

Description

technical field [0001] The invention relates to shaping the stamping parts after bending, in particular to a bending springback intelligent compensation device, a continuous mold and a bending springback compensation method for compensating the springback amount of the stamping parts after bending. Background technique [0002] Continuous die (also known as progressive die, skip die) refers to the punching die that completes multiple processes at the same time in several different positions in one stroke of the press. Every time the die is stamped, the strip moves at a fixed distance until the product is completed. The blanking parts are formed step by step in the continuous mold. Continuous forming is a process-intensive process method, which can make various processes such as trimming, incision, grooving, punching, plastic deformation (such as bending), and blanking in one process. Finished on the sub-mold. According to the actual needs of stamping parts, multiple stampi...

Problems solved by technology

[0005] The existing technology has the following defects in plastic surgery: firstly, because the hardness, thickness, and flatness of the raw materials have a certain tolerance range, the amount of springback after bending of the stamping parts is different, and the downward distance of the inserting knife is fixed, so The existing technology is difficult to make targeted compensation for different springbacks, and it is easy to over- or under-reshape, resulting in the need for repeated debugging to meet the customer's design requirements, which reduces the production speed; second, the existing technology requires manual inspection Whether the stamping parts meet the design requirements, the speed of manual inspection is slow, and the shaping of unqualified products often needs to be repeated many times to complete, during which multiple manual measurements are required, resulting in a large waste of human resources and low efficiency
