[0002] An anchor bolt refers to the general term for all post-anchoring components. According to different anchoring mechanisms, it can be divided into various types such as expansion anchor bolts and reamed anchor bolts. The main material of the anchor bolt is the bolt. In addition to the expansion structure, at least a gasket and a nut are installed on the bolt. Some anchor bolts also install a spring washer. Therefore, the production and processing of anchor bolts require multiple processes.

[0003] In the prior art, during the production of sleeve expansion anchor bolts, the bolt and the sleeve need to be assembled together. After assembling the bolt and the sleeve, it is necessary to punch the sleeve once to punch a concave point on the sleeve to prevent the sleeve from falling off the bolt. In the existing punching technology, the sleeve and the bolt cannot be clamped and positioned during punching, which easily causes the punching position to shift. And only one point can be punched on the sleeve, so the sleeve is easy to fall off the bolt, reducing the assembly quality and the product quality.

An L-shaped support rod 24 is installed on the telescopic end of the electric push rod 23. One end of the L-shaped support rod 24 away from the electric push rod 23 is fixedly connected to the support seat 21.

[0022] Specifically in actual applications, after the sleeve enters the assembly groove 11, the sleeve is located above the two support rollers 22. When the sleeve rotates, the support rollers 22 rotate, and the support seat 21 and the support rollers 22 are supported by the guide base plate 20 to avoid deformation of the support seat 21 and the support rollers 22 during rolling, thereby improving the service life. After the assembly is completed, the electric push rod 23 starts to work, and the telescopic end of the electric push rod 23 extends into the L-shaped support rod 24 to drive the support seat 21 to slide along the guide base plate 20. The two support rollers 22 move away from each other, increasing the distance between the two support rollers 22, and the sleeve type expansion anchor falls from between the two support rollers 22, which facilitates the unloading of the sleeve type expansion anchor and improves work efficiency.

[0026] Specifically in actual application, when the moving seat 28 moves, it drives the L-shaped fixing frame 33 to move, so that the rolling roller 36 is located above the sleeve. The hydraulic cylinder 34 starts to work. The telescopic end of the hydraulic cylinder 34 extends in to drive the U-shaped fixing frame 35 and the rolling roller 36 to descend, so that the anti-slip washer 39 on the rolling roller 36 abuts against the sleeve. The driving motor 37 starts to work. The output end of the driving motor 37 drives the rolling roller 36 to rotate. The anti-slip washer 39 on the rolling roller 36 contacts the sleeve. When the rolling roller 36 rotates, it drives the sleeve to rotate on the two support rollers 22. When the rolling protrusion 38 on the rolling roller 36 contacts the sleeve, the sleeve is rolled by the rolling protrusion 38.
