Bolt Factory's Production Knowledge

  •    Double-head bolt manufacturers introduce the basic knowledge and maintenance of double-headed wire


    The production of China Nut requires fixed equipment and machine tools. Of course, the processing procedure is relatively simple. The main processes are as follows: First, the material needs to be drawn. After this process, the next process can be carried out. The next process is to use a cutting machine to cut the straightened long material into the length required by the customer. This completes the second process, and the third process is to The cut short material is placed on the thread rolling machine to roll out the thread; the ordinary stud bolts are processed here. Of course, if other requirements are required, other processes are required.


       The commonly known bolt refers to a screw with a larger diameter. According to this statement, a screw has a much smaller diameter than a bolt. Stud bolts do not have a head, and some are called studs. Both ends of the stud bolts are threaded, the middle is not threaded, and the middle is a polished rod.


       Stud bolts are used on large equipment such as reduction racks. In actual use, the external load will vibrate and the influence of the temperature will cause the friction to become smaller, and the threaded connection will relax and fail over time. Therefore, it is necessary to do the maintenance work of the stud bolts in normal times.


    Stud bolts or anchor bolts will have problems under the action of mechanical friction for a long time. When there is a problem, the engine oil pan should be removed, and the use of the engine bearing bushes should be carefully checked, and the gap between the bearing bushes should be checked. Whether it is too large, if the gap is too large, replace it in time.


       The connecting rod bolt should be replaced when the stud bolt is replaced. Some large equipment such as nail making machines should be stopped for inspection in time if the engine is not running very stable or abnormal noise occurs during normal operation, so as to avoid bigger problems.


    In every repair, the newly replaced studs and other newly replaced accessories must be checked. The focus of the inspection is on the head and the guide part of the stud, and each part of the thread must be strictly checked. No cracks or dents, but also check the tooth shape of the stud to see if there is any change.


       Check whether there is any abnormality in the pitch, and if there is any abnormality, it must not be used again. The torque wrench should be used when installing the connecting rod cover. Must be tightened in accordance with the prescribed standards, the torque must not be too large or too small, but also pay attention to the choice of Bolt Factory studs and studs.
