Service HotlineOrdinary open rivet is a kind of product in rivet. It is riveted to the workpiece by expanding the rivet body after the big end of the mandrel is pulled. After the traditional rivet is riveted, the operator will cut the mandrel short, the mandrel does not work, and the workpiece is riveted by the material strength of the rivet body itself. After the mandrel is pulled, the middle of the rivet body becomes a cavity, and the mandrel shears The distance of the segments is relatively random. The random shearing determines the length of the cavity of the riveting body, and the length of the cavity determines the tensile and shear strength of the riveting body. The volume of the cavity is large, the tensile and shear strength is low, and the cavity is small. , the tensile and shear strength is slightly improved, so the breaking point of the rivet can completely affect the use effect of the rivet.
In the riveting connection of various structural parts, waterproof lantern rivets have been widely used in riveting environments that require waterproofing. After the riveting parts are riveted, the waterproof structure area of the mandrel and the waterproof structure of the rivet body There is no complete close fit between the areas. In some riveting ranges, the waterproof performance of the rivet is affected. The main reason is that the traditional processing technology of the mandrel and the materials used bring many troubles to the riveting process. is a problem to be solved at present.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a flat gasket that improves the lubrication performance of the contact surface and reduces the friction of the contact surface. Yueluo is implemented through the following technical solutions: a flat gasket with straight upper and lower end faces, characterized in that: the upper and lower end faces are dotted with pits, the pits are spherical pits, and the pit diameter is 2-3mm , the pit depth is between 0.5-lmm. The bottoms of some of the pits are provided with through holes penetrating the upper and lower end faces, and the diameter of the through holes is not greater than 0.5mm. The flat gaskets provided by Yueluo have pits with reasonable design parameters on the upper and lower end faces of the flat gaskets. The pits can store oil, so the lubrication of the contact surfaces of the gaskets can be well improved. It can effectively reduce the friction of the contact surface of the gasket and reduce the failure rate; in addition, the design of the through hole enables a smooth oil passage between the upper and lower end faces of the gasket, ensuring that the upper and lower end faces can be well lubricated.
At present, the installation methods of the retaining ring: 1. Most of them are installed with retaining ring installation pliers; 2. Simple installation aids; 3. Automatic retaining ring installation machine. The disadvantages of these installation methods: 1. If the manual installation is uneven, the elastic retaining ring will deform plastically, which will cause the elastic retaining ring to fail; 2. It cannot be positioned for complex structural parts, and the production efficiency is also low; 3. Simple installation Auxiliary tools are only suitable for the parts to be installed, which are generally not universal and have limitations; 4. The automatic elastic retaining ring installation machine has a complex structure and high cost.
