The pusher cylinder 13 is started to drive the feed plate 131 to retract. After the feed plate 131 retracts, the feed trough 132 is opposite to the feed channel 121, so that the workpiece is sent into the feed trough 132 through the feed channel 121. The pusher cylinder 13 is started again to drive the feed plate 131 forward, and the feed trough 132 drives the workpiece to the feeding position of the conveying mechanism 14.

Then, the translation necking cylinder 157 is activated to push the push block 156. The push block 156 rotates the necking clamping handle 155 through the fixed shaft. When the necking clamping handle 155 rotates, it abuts against the necking slider 1591 through the arc-shaped drive groove 1551. The necking slider 1591 drives the necking pressure knives 1592 to perform necking processing on the copper bracket workpiece. After processing is completed, the translation necking cylinder 157, the gripper cylinder 158 and the lifting necking cylinder 152 are reset. The turntable rotates to move the workpiece processed on the current fixture 16 to the next process. At the same time, another set of fixtures 16 is switched and moved to the bottom of the necking assembly 15 to prepare to receive the workpiece for processing.

[0035] In summary, this copper bracket is equipped with a necking device. The vibrating feeder 11, the direct vibrating feeder 12, and the pushing cylinder 13 work together to achieve automatic workpiece arrangement and conveying, reducing manual intervention. The handling mechanism 14 accurately grasps and transfers the workpiece through negative pressure adsorption, avoiding positioning deviation. Three equally spaced necking sliders 1591, in conjunction with the arc-shaped drive groove 1551, synchronously squeeze the copper bracket port under the drive of the translation necking cylinder 157, ensuring uniform force on the necking and avoiding deformation or dimensional errors.
