A guide box 200 is connected to the front side of the cold heading machine 100. Two sets of guide devices 300 are fixedly arranged on the left and right sides of the guide box 200. The guide devices 300 on the left and right sides are arranged in a mirror image. The left guide device 300 includes a rotating plate 310. A fixed plate 320 is fixedly connected to the front side of the rotating plate 310. A spring 330 is fixedly connected to the right side of the fixed plate 320. A rubber plate 340 is fixedly connected to the front side of the rotating plate 310. The right side of the spring 330 is fixedly connected to the rubber plate 340. A degreasing device 400 is fixedly arranged on the front side of the guide box 200. The bolts dropped from the cold heading machine 100 after processing can be reduced by setting the guide device 300. The impact force can improve the quality of the bolts after processing, avoid the collision of bolts when the bolts fall from the cold heading machine 100 into the bolt collection box after processing, and avoid the risk of damage to the surface of the bolts causing inconvenience in the subsequent thread rolling process and reduced quality, thereby improving the stability of the use of the device. A motor 350 is fixedly arranged on the rear side of the rotating plate 310, and the rear side of the motor 350 is fixedly connected to the guide box 200. The transmission end of the motor 350 is fixedly connected to the rotating plate 310. By setting the motor 350, the spring 330, the fixed plate 320, and the rubber plate 340 can be driven to rotate through the rotating plate 310, so that the rubber plates 340 on the left and right sides open the gaps for the bolts to pass through, thereby improving the stability of the use of the device and avoiding the occurrence of The bolts are stuck in the gap between the two groups of rubber plates 340. The degreasing device 400 includes a filter screen plate 410. The left and right sides of the filter screen plate 410 are fixedly connected with connecting rods 420. The left and right side walls of the guide box 200 are provided with grooves matching the connecting rods 420. A cylinder 430 is provided on the rear side of the filter screen plate 410. The rear side of the cylinder 430 is fixedly connected to the guide box 200. The telescopic end of the cylinder 430 is fixedly connected to the filter screen plate 410. By setting the degreasing device 400, the lubricating oil on the surface of the bolt can be cleaned, thereby reducing the lubricating oil on the surface of the bolt, thereby improving the convenience of subsequent processing of the bolt. The lower side of the guide box 200 is fixedly connected with a guide collection box 210. A collecting box 220 is fixedly connected to the front side. By setting a guiding collecting box 210 and the collecting box 220, it is convenient to collect the lubricating oil outside the bolts. A baffle 201 is fixedly connected to the front side of the guide box 200. A guide plate 202 is fixedly connected to the front side of the guide box 200.

[0022] Working principle: When the new solution is implemented, the bolts dropped from the cold heading machine 100 drop to the upper side of the guide box 200, and are guided by the baffle 201 and the guide collection box 210 to the upper side of the rubber plate 340. After the rubber plate 340 is hit by the bolt, the impact force of the bolt is reduced by its own material. At the same time, the rubber plate 340 is squeezed on the fixed plate 320 after being hit, so that the fixed plate 320 is squeezed and deformed, and then the rubber plates 340 on the left and right sides flip to leak out the gap for the bolt to move downward, thereby reducing the impact force generated by the bolt falling in the process, thereby In order to avoid the phenomenon of bolts falling and being damaged, the elastic force generated by the deformation of the fixing plate 320 drives the rubber plate 340 to return to its original position, and the bolts moved out from the guide device 300 fall to the upper side of the filter screen plate 410, and after the protective pad 411 reduces the impact force, they fall to the upper side of the filter screen plate 410, and then the cylinder 430 is started, and the cylinder 430 drives the filter screen plate 410 to move back and forth, and then the bolts are vibrated by the back and forth movement of the filter screen plate 410, and then the lubricating oil on the surface of the bolts is removed, and a conveyor belt is set on the front side of the guide box 200, and then the bolts dropped from the filter screen plate 410 are moved out through the conveyor belt.
