AI Technical Summary

Technical Problem

The existing bending process of transverse support steel wires for automotive seat backrests suffers from problems such as inaccurate positioning, difficulty in controlling bending angles, and limited applicability, resulting in poor product consistency and safety hazards.

Method used

The bending and forming device includes a back net positioning and clamping mechanism, a transverse support wire clamping mechanism, and a transverse support wire extension bending mechanism. Through a stepped height design, multi-point positioning, and motor gear meshing transmission, it achieves precise positioning and flexible adjustment of bending angle to form a hook-shaped, snap-on, or fitted structure.

Benefits of technology

It improves bending accuracy and consistency, avoids wire loosening and stress concentration, meets different assembly requirements, and enhances product stability and safety.

Abstract

The application discloses a bending forming device and a method thereof, the device comprising: a base, a back net positioning and clamping mechanism, at least two transverse support steel wire clamping mechanisms and a transverse support steel wire extension section bending mechanism; the method is suitable for the bending forming device, and a stepped height design is adopted to make the back net present an actual assembly inclined posture, so that precise alignment of the bending station is guaranteed. The back net is positioned through flexible compression at multiple points, and the arc-shaped groove cooperates with the parallelogram link and the inclined surface support to prevent scratch and stabilize the position. The steel wire is rigidly limited through the cross groove and the locking push column, so that the movement and swing during bending are eliminated. The bending mechanism controls the angle through motor gear transmission and mechanical limiting, and the arc-shaped bending block and the guide block avoid stress damage of the steel wire. Various bending structures can be formed flexibly by adjusting parameters, different assembly requirements are adapted, and the precision and adaptability are far higher than those of the traditional mode.
