The installation method of rear reaming bolts is different from other mechanical bolts. Now the installation methods and steps of rear reaming bolts are listed for reference. According to the diameter and depth of the straight hole required in the instructions, drill a straight hole of the correct size by matching the straight hole drill bit. The matching special reaming bolt bit is used for secondary reaming, the dust collector is used for dust removal in drilling, and the copper clip on the knocking sleeve is used for impact installation. After installation, remove the impact cylinder and tighten the washer nut with a torque wrench. Precautions should be known in advance to ensure that the bolt parameters after reaming are in place to ensure the size of the perforation and reaming, otherwise, there is a safety hazard of blowing soot no less than three times, and it is necessary to ensure that the size of the dry hole needs to be tested , to ensure that the hole position can be accurate according to the tap. The timing of the blow and the sound of the installation location determine whether the rear bolts are installed in place.
Rear expansion bolt is a common product in work and life. How to keep the mechanical anchor clean is particularly important, which directly affects the effect of the mechanical anchor. When using mechanical anchor bolts for a long time, due to some reasons, there will be some stains on the surface, which will affect the whole working process. In the past, manual cleaning was used during mechanical anchor bolt cleaning, but for some parts, it was not convenient to clean. In order to solve this problem, some businessmen have invented and produced ultrasonic cleaning machines, which are specially used to clean mechanical anchor bolts and apply a clean coating to the mechanical anchor bolts to reduce the labor intensity of workers and improve production efficiency. Of course, stainless steel cleaning fluid can also be used, and we should also remind us to wipe it with a dry cloth and not let water stay on the surface of the mechanical anchor bolts.
