Service HotlineThe shear strength of a metal material refers to the ability of the material to withstand shearing force, which refers to the strength of the external force perpendicular to the material axis and shearing the material. The test is usually to install the cylindrical pin into the specified fixture, and the gap between the supporting part and the loading part is required to be no more than 0.15mm, and then force is applied to test the shear strength of the material.
The manual dismantling of the rivets of the automobile frame delays the production cycle of the product and increases various production costs, so a special tooling is desperately needed to meet the actual needs.
With the mass production of large-scale equipment, standardization, and the concept of lean production, it has become more and more important to improve the efficiency of the assembly stage. Nowadays, when assembling small equipment, power tools and automatic bolt supply devices are basically popular, but only for M3 and smaller However, large equipment is often fastened with M8 or larger diameter bolts, and it is still in the process of combining manual and air tools. Among them, the pre-installation of the flat and spring washers on the bolts is completely manual operation. When the bolts need to be tightened in large quantities, the shortcomings of low efficiency are particularly obvious, and the flat and spring washers are easy to be scattered when manually assembled, and there are mixed installations of different specifications. Problems such as less installation and missing installation will affect the processing quality.
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.
Commonly used are R-type rivets, fan rivets, blind rivets (blind rivets), tree rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, hollow rivets, these are usually used Self-deformation connection is riveted. Generally less than 8 mm with cold riveting, larger than this size with hot riveting. But there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole.
