Description

Technical Field

[0001] The invention relates to the field of automobile wiring harnesses, and in particular to a wire straightening device for an automobile wiring harness production line. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added, etc., to form a component that connects the circuit. It can be seen that the main body of the automotive wiring harness is still assembled through several cables, and the cables used to produce automotive wiring harnesses are mostly produced by separate manufacturers. After production, the cables are generally wound in bundles. Because these cables are set in bundles, the cables themselves have a certain degree of curvature before they are cut to the specified length. In order to facilitate subsequent operations such as stripping and crimping, straightening operations are generally performed before cutting, so that the cut wire harness will become relatively straight.

[0003] The cable itself is relatively soft and easy to deform, so the traditional straightening method used for metal rods cannot be used here, and the raw material cable is relatively long as a whole, so how to achieve long-term and stable and effective straightening and cutting according to the specified length cannot be well achieved. The existing technology can only straighten a certain length according to the regulations, and then stop the machine for manual control cutting, which is time-consuming and labor-intensive, and the production efficiency is relatively low.

The top end of the adjusting rod 69 is threaded, and a threaded hole is provided inside the adjusting handle 70. The top of the adjusting rod 69 is screwed into the threaded hole. By rotating the adjusting handle 70, the adjusting handle 70 can drive the top of the adjusting rod 69 to move up and down through the threaded hole inside it, thereby changing the overall height of the adjusting rod 69. At the same time, the adjusting rod 69 can drive the slider 65 to rise and fall synchronously, and finally change the height of the pressing roller 64. According to the specifications of the wire, the pressing roller 64 can cooperate with the cross roller 63 to better stabilize the wire.

Flip the notch groove 82 of the flip plate 77 to the position of the vertical plate 71 near the rocker bar 80, then rotate the rocker bar 80 into the notch groove 82, and turn the locking button 81 to position the flip plate 77. The pressure wheel 79 can be adjusted to be directly above the support wheel 75. The wire straightened by the straightening mechanism 3 passes through the inside of the wire-winding mechanism 4, and then passes between the pressure wheel 79 and the support wheel 75. This can ensure the stability of the wire harness after straightening, which is convenient for subsequent cutting.
