What is the tolerance range of precision screws?
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.
Many customers ask what is the difference between a rivet nut and a rivet nut, and how to use it? Let's take a look at the difference between a rivet nut and a rivet nut with Yueluo. First of all, in terms of appearance, you can look at the differences in appearance. In terms of appearance, the difference between the rivet nut and the pressure rivet nut is still very big, but their main functions are almost the same. They all provide threads for thin plates, but the way of installation is different. The method of installation greatly determines the purpose and use of a nut. First of all, the installation method of the riveting nut is to use the riveting equipment to carry out the riveting, so it is suitable for use in the place where the riveting is not easy for the square tube and the round tube. The rivet nut also makes up for some of the shortcomings of electric welding, such as aesthetics, and places that are not easy to weld, such as thin plates.
Embedding of fasteners, especially screws. The main point of the structure is that it includes an annular base, one at the base and a plurality of cylindrical tubes on the base, and the cylindrical tubes and the cylindrical tubes on the base are connected by ribs. Cylindrical tubes are used as fixing holes and fastener pre-embedded holes respectively. The product is fixed on the formwork that needs to use screw points through the fixing holes. After the concrete is poured into the floor, the embedded screw parts are pre-embedded, and the floor has embedded screw holes for hanging the installation objects with screws. . Avoid future re-drilling damage to the wall and floor. Guangdong Yueluo Hardware Industry Co., Ltd. has a simple and scientific structure, easy pre-embedding, strong tensile strength and firmness.
Pre-embedded copper nuts with straight pattern/twill pattern/herringbone embossing and other various anti-skid patterns can be completed at one time by automatic lathes. More complex copper nuts are processed by forming knives and table turning/tapping. Many products processed after machining are relatively simple reticulated copper nuts and straight-grained copper nuts, which are made of C3604 easy-turning brass. The surface pattern is directly drawn from the original bar, and the pattern is full and the tooth peak and bottom are clearly visible. Injection molding into plastic parts Afterwards, it can bear more high torque.
