First of all, we should tell you that the production of stud bolts requires fixed equipment and machine tool processing. Of course, the processing procedure is relatively simple. There are mainly the following procedures: first, the need for drawing. Drawing is to use the drawing machine to straighten the distorted material. After this process, the next process can be carried out. The next process is to use the cutting machine to cut the straightened material into the length required by the customer, This completes the second process, and the third process is to put the cut short material on the thread rolling machine to roll out the thread; The common stud bolts are processed here. Of course, if other requirements are required, other processes are also required.

Generally known bolts refer to screws with larger diameters. According to this statement, the diameter of screws is much smaller than that of bolts. Stud bolts have no head, and some are called studs.

Both ends of the stud bolt are threaded, without thread in the middle, and the middle is a polished rod. Stud bolts are used on large equipment, such as reduction frame. During the practical application, the external load will vibrate and the influence of temperature will show that the friction will decrease, and the thread connection will relax and fail over time. Therefore, it is necessary to do a good job in the maintenance of stud bolts at ordinary times.

Stud bolts may be foundation bolts that may have problems under the effect of long-term mechanical friction. When problems occur, the engine oil pan should be removed, and the use of engine bearing shells should be carefully checked to see if the gap between bearing shells is too large. If the gap is too large, it should be replaced in time. Replace connecting rod bolts when replacing stud bolts. Some large equipment, such as nail machine, may make abnormal noise when it is found that the engine is not running stably during normal operation. It is also necessary to stop and check in time to avoid more serious problems.

At the time of each repair, it is recommended to check the newly replaced stud bolts and other newly replaced accessories, focusing on the head and guide part of the stud bolts, strictly checking whether each part of the thread has cracks or dents, and also checking whether the tooth shape of the stud bolts has changed. If the pitch is abnormal, it can't be used again. The torque wrench should be used when installing the connecting rod cap. It must be tightened according to the rules and specifications, and the torque should not be too large or too small, and attention should be paid to the selection of stud bolts and studs from matching manufacturers.
