Manual shaping fixtures use cylinder-driven shaping blocks, which cannot achieve high-precision shaping, have unadjustable pressure, and each shaping dimension varies. Currently, manual shaping fixtures for small C-ring bends are limited to manual shaping or cylinder-driven shaping. Overall shaping efficiency is low, yields are low, and employees are time-consuming and labor-intensive, significantly increasing labor costs during mass production. This poses new requirements and challenges for cost reduction and efficiency improvement in C-ring bending.
[0003] At the same time, the use of manual shaping or simple cylinder clamp shaping can easily lead to large errors, improper clamping, low shaping yield, and poor repeatability; and manual operation of employees can easily cause visual fatigue, thereby increasing the risk of product defects. Therefore, in response to the above problems, this application proposes a solution. Summary of the Invention
