Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety of specifications, different performance uses, and a very high degree of standardization, serialization and generalization. Therefore, some people also refer to a type of fasteners with existing national standards as standard fasteners, or simply as standard parts. Fasteners are the most widely used mechanical foundations. With my country's entry into the WTO in 2001, it has entered the ranks of major international trade countries. my country's fastener products are exported to many countries in the world, and fastener products from all over the world are also pouring into the Chinese market. Fasteners, as one of the products with the largest import and export volume in my country, are in line with international standards, which have important practical significance and practical significance for promoting Chinese fastener enterprises to go to the world and promoting fastener enterprises to fully participate in international cooperation and competition. strategic significance. Due to the specifications, dimensions, tolerances, weights, properties, surface conditions, marking methods, and specific requirements of items such as acceptance inspection, marking and packaging for each specific fastener product.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a kind of rivet, parts and parts are riveted by the rivet, the part has a fixed plate and a fixed plate, and the part is located between the fixed plate and the fixed plate, The rivet includes a nail head, a nail post and a nail post which are connected in sequence, the diameter of the nail post is larger than the diameter of the nail post, the nail head is matched with the outer end surface of the fixing plate, and the length of the nail post is It is greater than the sum of the riveting length of the fixing plate and the riveting length of the part. The rivet can control the distance between the parts, so that the relative rotation of the two parts is more smooth and easy to operate.
Stainless steel screws, as the name suggests, must be made of stainless steel screw wire, and then screw the screw thread. Many of the properties of stainless steel screws are related to stainless steel. Taking into account the properties and organization of stainless steel, understand the properties of stainless steel materials and other aspects. Therefore, it is understood that stainless steel has good mechanical properties such as anti-rust, anti-corrosion, high temperature resistance, etc., then stainless steel screws also have these good mechanical properties. With the increasing quality of stainless steel materials. The mechanical properties of stainless steel screws produced by the screw industry are getting better and better. Anti-rust, anti-corrosion ability, and high temperature and high pressure are getting stronger and stronger.
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 material needs to be pulled out. After this process, the next process can be carried out. The next process is to use a cutting machine to cut the straight and long material into the length required by the customer according to the customer's requirements. This completes the second process. The third process is Put the cut short material on the thread rolling machine and roll out the thread; the ordinary stud bolts are processed here, of course, if other requirements are required, other processes are required. [1] The commonly known bolt refers to the screw with a larger diameter. According to this statement, the diameter of the screw is much smaller than that of the bolt. Stud bolts do not have a head, and some are called studs. Both ends of the stud are threaded, with no thread in the middle and a smooth rod in the middle. Studs are used on large equipment such as gear racks. In actual use, the external load will have vibration and the influence of temperature will reduce the frictional force, and the threaded connection will loosen and fail over time. Therefore, it is necessary to do a good job in the maintenance of the stud bolts at ordinary times. Stud bolts or anchor bolts will have problems under the action of mechanical friction for a long time. When problems occur, the engine oil pan should be removed, and the use of the engine bearing bushes should be carefully checked, and the clearance between the bearing bushes should be checked. Whether it is too large, if the gap is too large, it should be replaced in time. When replacing the stud bolts, also replace the connecting rod bolts. When some large equipment such as nail making machines are in normal operation, if they find that the engine is not running very stable or there is abnormal noise, they should stop and check in time to avoid bigger problems. [1] In each maintenance, the newly replaced stud bolts and other accessories should be inspected. During the inspection, the focus should be on the head and guide part of the stud bolt. Whether there are cracks or dents in each part, and also check whether the tooth shape of the stud bolt has changed. Is there any abnormality in the thread pitch? If there is any abnormality, it must not be used again. A torque wrench should be used when installing the connecting rod cover. It must be tightened according to the specified standards, the torque should not be too large or too small, and attention should be paid to selecting the stud bolts and studs of the supporting manufacturer.
Combination bolts refer to a bolt with a spring washer and a flat washer, which are combined by rubbing teeth. Before the combination bolt is used, the bolt, the spring washer and the flat washer are generally combined by a specific machine. The combined production line mainly includes the processes of feeding, discharging, feeding, charging, screwing and tightening. The existing combined bolt production equipment mainly transmits the bolts to each process through the conveyor belt, and finally completes the combined assembly. The machines in each process are scattered and the space is occupied. The vibrating plate feeding generally puts the bolt head up, and its bolts, spring washers, etc. After the flat pad is assembled, the fixation is poor, and it is easy to fall off during the assembly process.
