Service HotlineThe technical solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve the problems of the prior art is: a patch nut, which is characterized in that it includes a nut body, and the nut body has a welding end face, and the edge of the welding end face forms a The serrated teeth protruding outwards of the ring.
The rivet nuts are divided into S series, CLS series and SP series. It provides a simple method for installing internal threads on precision metal sheet products, and plays a reliable fixing role. The small and delicate nut enables the plate to be embedded and processed on one side. When installing, just insert the nut into the hole of the metal plate. , to complete the setting firm function with pressure. When choosing to buy a rivet nut, you only need to provide a few elements: 1. Installation thickness 2. Internal thread size 3. What height do you require the nut to protrude from.
A kind of screw provided by Yueluo, the rod body of the screw rod has a thread segment, and the two ends of the thread segment are respectively provided with annular and two convex rings. The nominal size of the thread segment, and the distance from the convex ring at the rear end of the screw in the screwing direction to the rod core is greater than the nominal size of the thread segment.
The technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the deficiencies of the existing rivets. The purpose of this utility model is to provide a special rivet for railway freight cars, which can be reused and increase the safety factor. , to limit the movement of the collar in the circumferential direction.
When checking the finished blind rivet, check: the diameter of the rivet body, the length of the rivet body, the thickness of the rivet body cap, the diameter of the cap, the total length of the mandrel, the exposed size of the mandrel, the size of the nail cap, and the outer diameter after assembly can be considered. In the actual inspection, the weak links of the product can be measured, such as: tensile force, shear resistance, and core pull-out resistance. The key is to pay attention to the rivets, if the rivets are insufficient, whether they are riveted in place; or because the cap of the mandrel is too large, so that the mouth of the rivet body cannot be pulled down; and there are jump heads, that is, the mandrel is too low or broken. The size is too small etc. Length measurement of closed blind rivets
