Product Details
A rivet is a nail shaped object used to connect two parts or components with through holes and a cap at one end. In riveting, the riveted parts are connected using self deformation or interference. There are many types of rivets, and they are not limited to their forms. The commonly used ones include R-shaped rivets, fan rivets, pop rivets, punch rivets, tree shaped rivets, half round head, flat head, half hollow rivets, solid rivets, countersunk head rivets, pop rivets, and hollow rivets. These are usually connected to the riveted parts using their own deformation. Generally, cold riveting is used for sizes smaller than 8mm, and hot riveting is used for sizes larger than this size. But there are also exceptions, such as the nameplate on certain locks, which is riveted using the interference between the rivet and the lock body hole.
In order to solve the problem of nut loosening, various types of self-locking nuts have emerged, which have complex structures, high production costs, inconvenient installation, and unsatisfactory anti loosening effects. Currently, the most commonly used type is the Japanese produced non loosening nut, which mainly adopts a double nut form. Each nut is equipped with an eccentric cam protrusion, and each nut is equipped with a groove and an inclined plane to compress the cam protrusion of each nut. When the nut is continuously rotated, the cam protrusion of each nut will move towards a small radius along the inclined plane of each nut, achieving that the nut will not loosen, But whether it is a nut or a nut, it is always subjected to eccentric force. In addition, many manufacturers design various types of non loosening nuts to achieve the goal of never loosening by increasing the friction force between the nut and the fastening workpiece or increasing chamfering, but the effect is not ideal.
Locating pin is a pin designed for accurate positioning of two adjacent parts of the mold in the mold composed of two or more parts. It can be seen that the locating pin is the product that plays the role of positioning. The mold must be accurately synchronized when it is closed, and the locating pin can make the upper and lower the second mock examination play the role of accurate positioning. In the mold design and manufacturing of Yue Luo, the positioning pin is one of the common parts. As it is only used for positioning between parts, few people pay too much attention to it. In the cold stamping process of Yueluo, the dimensional accuracy of the punched parts depends on the size of the working parts of the convex and concave molds, and the difference in size between them constitutes the gap between the punching molds. Clearance is an important process parameter in the design of stamping dies, and its size has a significant impact on the quality of the cross section of the workpiece, the punching force, and the lifespan of the mold. Excessive clearance can result in burrs during punching and shearing; If the gap is too small, secondary cracks and extrusion burrs will appear on the cross-section, which can lead to unsatisfactory quality of the punched cross-section. However, a reasonable gap not only helps to improve the quality of the punched cross-section, but also helps to improve the lifespan of the 15 steel tools.
According to the above plan, the height of the step part is less than or equal to the thickness of the riveted part. The beneficial effect of this utility model is to provide a riveting nut column, which reduces the fit gap with the aluminum profile riveting bottom hole, transforms the gap fit into a transition fit, increases the clamping force of the riveting nut column, and enables it to resist greater assembly impact and torque when installing screws, ensuring that the riveting nut column is not loose, and is suitable for spray painted aluminum profile panels with high surface quality requirements. Figure 4 is an installation schematic diagram of an embodiment of the present utility model.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a new type of open core rivet suitable for riveting aluminum Al, steel St, and stainless steel SST thin sheets with foam material in the middle. The new type of rivet improves the nail core process by using an aluminum core rod. The head of the core rod has pits that are easy to deform, and there is a conical stop groove above the breakpoint of the core rod. The stop plate can clamp the core rod to prevent the nail head from being exposed, while locking the core rod to prevent loosening.
