The slide groove 22 is used for the gasket to pass through. The slide bar 21 can adopt a guide rod or a slide rail. The design of the slide groove 22 should match the size of the gasket to prevent the gasket from shifting during the transportation process. In order to further improve the accuracy of the gasket transportation, a plurality of balls or rollers can be provided in the slide groove 22 to reduce the friction between the gasket and the slide groove 22, so that it can move smoothly from the loading tray 1 to the screw blank positioning mechanism 3.

[0031] A screw blank is arranged in the screw blank positioning mechanism 3, and the screw blank can be transported to the bolt blank positioning mechanism through other conveying structures. The screw blank positioning mechanism 3 includes a positioning seat 31 and a clamping device 32. The positioning seat 31 is provided with a groove 33 matching the screw blank. The positioning seat 31 can be made of high-strength alloy material to withstand the greater pressure generated during the thread rolling process. The shape of the groove 33 can be designed according to the outer contour of the screw blank, usually circular or special-shaped, to ensure the accuracy of positioning. A suction cup 34 is provided at the bottom of the positioning seat 31. The suction cup 34 is used to adsorb the gasket sleeve on the screw blank, thereby completing the loading of the gasket. The suction cup 34 can be a vacuum suction cup 34 or an electromagnetic suction cup 34. The vacuum suction cup 34 is suitable for gaskets of various materials, and the electromagnetic suction cup 34 is suitable for metal gaskets.
