Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. provides a nut provided by Yueluo, which includes an internal thread. is an arc curve. Compared with the nut of the same type, the normal pressure and friction force of the nut are increased, the thread is not easy to loosen, and the bolt and nut are in surface contact, so it is not easy to cause stress concentration and local material yield, which effectively improves the tightening force of the bolt and nut. Stability, increase fastening reliability.
pressure riveting nut pressure riveting tool Yueluo relates to a tool, specifically a pressure riveting nut pressure riveting tool. [Background Art] In order to quickly press riveting nuts, and to quickly switch press rivet nuts of different specifications and properties, and to ensure the press riveting strength between the press riveting nut and the piece during the press riveting process, a kind of Press riveting tooling. In order to overcome the deficiencies of the prior art, Yueluo provides a pressure riveting tool that can improve the strength of the pressure riveting and can switch the pressure riveting nut of different specifications and properties.
(1) The surface rust, oil stains, burrs on the wall of the bolt holes, welding flashes, etc. should be cleaned up. (2) After the contact friction surface is treated, the specified anti-scratch coefficient requirements must be met. The high-strength bolts used should have matching nuts and washers, which should be used in accordance with the matching and should not be interchanged. (3) When the friction surface of the treated component is installed, it is not allowed to be stained with oil, soil and other sundries. (4) The friction surface of the module should be kept dry during installation and should not be operated in the rain. (5) Strictly check and correct the deformation of the connected steel plates before installation. (6) It is forbidden to hammer into the bolt during installation to prevent damage to the bolt thread. (7) The electric wrench, which is regularly tested during use, ensures the accuracy of the torque and operates in the correct tightening sequence. Main safety technical measures (1) The size of the wrench of the adjustable wrench should be consistent with the size of the nut, and the sleeve should not be added to the small wrench. A dead wrench should be used for high-altitude work. For example, when using an adjustable wrench, use a rope to fasten it, and people should fasten their seat belts. (2) When assembling the connecting bolts of steel components, it is strictly forbidden to insert your hands into the connecting surface or touch the screw holes. When picking and placing the bolster, your fingers should be placed on both sides of the bolster.

In all kinds of machines and equipment, the various parts are fixed and assembled by bolts and nuts. However, after the machine and equipment are used for a period of time, the bolts and nuts will become loose, which will bring great safety hazards to the use of the machine and equipment. For this reason, when bolts and nuts are used for connection, a spring washer is installed between the nut and the connected part. The spring washer is in the shape of a circular ring, and the ring is not closed, and is sleeved on the bolt. The addition of the spring washer has a certain anti-loosening effect, but it can only prevent the nut from rotating relative to the bolt. In the case of large vibration of the machine, the bolt will rotate relative to the connected part.
