AI Technical Summary
The existing air volume regulating valve frame requires manual support to bend the steel sheet at a 90-degree angle during processing. This is especially laborious and unstable when handling large steel sheets, posing a safety hazard.
A bending device for producing air volume regulating valve frames was designed. Through the linkage of the sliding plate and the flipping plate, the steel sheet is automatically supported to bend at 90 degrees. Combined with the limiting and adjusting mechanism, it ensures that the steel sheet does not deviate during the bending process and can adapt to different sizes, thereby controlling the fold width.
It achieves the goal of eliminating the need for manual support, saving manpower, improving safety and stability, and adapting to the processing needs of steel sheets of different sizes.
