The core rivet is another type of single-sided riveting. When riveting, the head of the rivet is hit with a hammer to expose the core, so that it is flush with the end face of the nail head, that is, the riveting operation is completed, which is very convenient, especially suitable for inconvenient Riveting occasions using ordinary rivets (which must be riveted from both sides) or blind rivets (lack of a rivet gun). Usually use flat head rivets, countersunk head rivets are suitable for occasions where smooth riveting is required on the surface.
rivet is a nail-shaped object with a cap on one end: in riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal. Commonly used are semi-circular head, flat head, semi-hollow rivet, solid rivet, countersunk head rivet, blind rivet, hollow rivet, which usually use their own deformation to connect the riveted parts. Generally, cold riveting is used for those smaller than 8 mm, and hot riveting is used for larger ones. But there are exceptions, such as the nameplate on the three-ring lock, which is riveted by the interference between the rivet and the lock body hole. In addition, there are paired rivets, which are special. Divided into two parts, the thicker section of the rod with a cap has a hole in the center, and the other section of the rod with a cap is an interference fit. When riveting, drive the thin rod into the thick rod. Most of the existing rivets are connected by overall deformation to achieve mutual cooperation. In the ultra-fine-pitch display screen, the rivets used to fix the ultra-fine-pitch display screen have a slender diameter. If they are fixed by overall deformation, they are prone to bending and breaking. and other phenomena, the tightening effect is not good or there is no tightening effect, which damages the components, increases the cost, and wastes time and resources.
double-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
In order to solve the above-mentioned technical problems, a technical scheme adopted by Guangdong Yueluo Hardware Industry Co., Ltd. is: a rivet capable of selecting a breaking point is provided, comprising a nail body and a mandrel, and the mandrel is sequentially provided with from the head to the tail. Hemispherical head, cone and cylinder, the cones are provided with at least three, the mandrel penetrates into the nail body from the bottom of the nail body, and then goes out from the head of the nail body, the hemispherical head and the cylinder Exposed on the bottom of the nail body and the outside of the head, the cones are all arranged inside the nail body.
Further, it also includes a motor, the motor is provided with a thruster that makes the cutting wheel move towards the conveying device, the other end of the motor is provided with a bearing, the output end of the motor is provided with a special-shaped wheel, the special-shaped wheel is toothed with the bearing, and the motor drives the special-shaped wheel to rotate. , move the cut-off wheel closer to or away from the conveyor.
