Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, specifically to a continuous bending machine. Background Technology

[0002] Bending equipment plays an increasingly crucial role in numerous fields, from the construction of metal frames in the building industry to the precision forming of electronic device housings and the processing of automotive parts. The applications of bending equipment are ubiquitous, driving continuous technological innovation to adapt to the rapid pace of development across various industries.

[0003] Chinese patent CN207563653U discloses a straight spring frame bending machine head, including a frame, a wire feeding mechanism on the frame, and a bending mechanism at the outlet of the wire feeding mechanism. The bending mechanism includes a downward bending mechanism that bends both ends of the steel wire downwards, an inward bending mechanism on both sides below the downward bending mechanism that further bends both ends of the downwardly bent steel wire inwards, and an upward bending mechanism below the inward bending mechanism that further bends both ends of the inwardly bent steel wire upwards to form a closed structure. However, this bending machine still has the following problems:

[0004] This bending machine uses inward and upward cutting blades to finally shape the wire. However, the drive unit needs to stop when it moves the wire to the designated position via the rotating wheel. After the wire is shaped, the drive unit restarts. Repeated starting and stopping can easily cause drive unit failure.

[0005] Based on this, the present invention designs a continuous bending machine to solve the above problems. Utility Model Content

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A continuous bending machine, including a mounting plate 11;

[0037] In this invention, the straightening drive assembly 23 drives the steel wire 13 to move intermittently to the right, while the first straightening assembly 21 straightens the steel wire 13 in the horizontal direction and the second straightening assembly 22 straightens the steel wire 13 in the vertical direction. The steel wire 13 is straightened multiple times to improve the straightening effect. When the straightening drive assembly 23 stops driving the steel wire 13 to move to the right, the cutting assembly 3 cuts the steel wire 13, and the unloading bending mechanism 4 bends the cut steel wire 13 into shape. The unloading bending mechanism 4 drives the formed bent finished part 14 to move forward to achieve automatic unloading. The above process is repeated to achieve continuous bending of the bent finished part 14 and improve production efficiency.

[0041] In this invention, the drive block 235 is driven to rotate by the output of the drive motor 234. The lower end of the universal ball bearing 237 slides along the upper end of the drive block 235. When the lower end of the universal ball bearing 237 slides from the lower plane to the upper plane via the inclined plane, the universal ball bearing 237 drives the mounting bracket 238 and the active roller 243 to move upward via the slide rod 236. The spring 239 is compressed, and the side wall of the active roller 243 is in contact with the side wall of the steel wire 13. The output of the drive motor 242 drives the active roller 243 to rotate. The active roller 243, in conjunction with the driven roller 231, drives the steel wire 13 to move to the right. At this time, the cleaning roller 212 cleans the steel wire 13. The sidewall of wire 13 is cleaned to prevent impurities from affecting the straightening effect of wire 13.

When the lower end of universal ball 237 slides from the upper plane to the lower plane via the inclined plane, spring 1 239 drives the baffle 240 and slide rod 1 236 to reset, and the sidewall of drive roller 243 separates from the sidewall of wire 13.
