Horizontal bolt cold heading forming machine

Abstract

The invention relates to the field of bolt machining, and discloses a horizontal bolt cold heading forming machine which comprises a bolt cold heading forming system, and the bolt cold heading forming system comprises a visual recognition module, an intelligent feeding module, a forming control module, a mold replacement module, a quality prediction module and a beat optimization module. And the visual identification module is used for carrying out rapid identification and positioning on the blank by adopting a YOLOv8 target detection algorithm and deep convolutional neural network variation based on industrial camera image acquisition, and enhancing the edge contour extraction precision through an image segmentation algorithm U-Net. Blank space pose information is obtained through a target detection and image segmentation method based on image recognition, precise positioning is performed through a geometric center fitting mode, the positioning efficiency and recognition precision are remarkably improved, and a six-degree-of-freedom path planning algorithm is combined with a self-adaptive clamping strategy, so that the positioning precision is improved. High-precision grabbing and feeding of blanks of different specifications are achieved, the feeding rhythm is adjusted and controlled through closed-loop feedback, and it is effectively guaranteed that the feeding rhythm is stable.
