Service HotlinePin riveting is an important procedure in the production process. At first, people used manual work, which has low production efficiency, high production cost, and high defect rate of products produced. Later, a pin riveting machine appeared. The pin riveting machine is a For riveting and pinning of hardware products, the pin riveting machine can complete the operation of pin loading and riveting pins, and the pin riveting machine reduces the process of pin loading and riveting pins in the hardware production process. However, its structural design is unreasonable and the operation is very inconvenient
In order to solve the above-mentioned technical problems, the technical solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. is: shear rivets, including a mandrel and a deformation sleeve ring sleeved on the mandrel, one end of the deformation sleeve ring is a boss structure, and the It includes an adhesive collar sleeved on the deformation collar, the adhesive collar is a hollow annular sleeve and is filled with adhesive material; one end of the mandrel is a hemispherical head, and the spherical surface of the hemispherical head is outward, The connection between the hemispherical head and the mandrel is a conical connecting section, and the diameter of the conical connecting section gradually decreases from the hemispherical head inward; the mandrel is provided with a stress concentration groove, and the position of the stress concentration groove is close to the deformation The boss structure of the collar.
Process equipment for aircraft production (hereinafter referred to as tooling) is directly used for part forming and component assembly. In order to satisfy the loading and unloading of aircraft parts and components during the use of the tooling, the tooling generally adopts a structural form that is easy to disassemble as a whole. In the field of aircraft process equipment manufacturing, positioning pins are usually used to connect and position the detachable parts of the tooling. At present, this kind of locating pin is divided into two types: direct pull-out locating pin and tie-suspended locating pin.
Advantages of anti-loose washers 1. Ensure that the clamping force of the connection is still maintained under strong vibration, which is better than fasteners that rely on friction to come from the lock; 2. Prevent the loosening of bolts caused by vibration, which no longer occurs due to fasteners related problems caused by loosening; 3. No special installation work is required, and it is easy to install and disassemble; 4. The temperature changes will not make the connector loose; 5. Durable; 6. Reusable.
Drilling screw is a new invention of people in recent years. A screw is a common term for fasteners, an everyday colloquial language. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination. It is easy to use safe drilling and tapping in one operation. Drill tail screw Drill tail screw use: It is a kind of screw, mainly used in the fixing of color steel tiles of steel structures, and can also be used for thin plate fixing of simple buildings. It cannot be used for metal-to-metal bonding. Materials and models The materials are iron and stainless steel, of which stainless steel is divided into various materials. Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon request. According to the different drill tails, it can be divided into: round head rice / cross / plum blossom, countersunk head (flat head) / rice seed / cross / plum blossom, hexagonal washer, round head washer (big flat head), horn head, etc.
