Service HotlineStainless steel rivet nuts are used on rail passenger cars, highway passenger cars, and ship parking. The main function is the non-structural bearing bolt connection. The main advantage of stainless steel rivet nuts is that there is no operating space on the back of the substrate, and the quality is extremely light. Today, the editor will talk about the selection principles of stainless steel rivet nuts and their uses: 1. The mechanical properties of stainless steel rivet nut materials, especially the strength requirements; Corrosion resistance requirements of materials;
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.
The circlip extrusion and positioning mechanism includes a vertically installed circlip sleeve rod and a linear module controlled by a positioning motor; a plurality of circlips to be installed are sleeved on the surface of the circlip sleeve rod; the surface of the linear module can be Mobile installation quick clamp; the clamping mouth of the quick clamp is a tight top plate; the tight top plate is in contact with the upper circlip and moves up and down with the up and down movement of the circlip sleeve;
In terms of screw standard specification broadcast, there are two versions of the national standard, one is GB70-76, the 76 version, and the other is GB70-8585 version. Our company is now implementing the DIN912 standard, so it should be paid attention to in actual business operations. Difference: GB70-85 and DIN912 completely overlap, so there is no difference in the use of the new standard, mainly because there is a difference between GB70-76 and DIN912: M8 series hexagon products, GB70-76 round head diameter It is 12.5MM, which is smaller than 13.27MM of DIN912. For M10 series inner hexagon products, the round head diameter of GB70-76 is 15MM, which is smaller than 16.27 of DIN912. The inner hexagon of M12 series, the round head of GB70-76 The diameter is 18MM, which is smaller than the opposite side of DIN912, which is 18.27. In addition, the round head diameter of the inner hexagon GB70-76 of M16 and M20 series is 0.33MM smaller than that of DIN912, which are 24MM and 30MM respectively. DIN912 is 24.33MM and 30.33MM respectively. In addition, the width of the inner hexagon between the old standard and the German standard is different due to different standards. The inner side of GB70-76 is smaller, and it should be paid attention to in business operations. In addition, there are also some differences in the carriage screws that may be used at ordinary times. I will also make an explanation here. In the national standard, there are two standards for carriage screws, namely GB12 (small semicircular head square neck screw) and GB14 (large semicircular head square neck screw) Neck screws), and the German standard DIN603 is usually more commonly used in the market. Now to distinguish these three: for the round head and neck, when comparing the same specifications: GB12
The shaft and gear of financial self-service equipment are often connected by elastic straight groove cylindrical pins. When repairing, the traditional disassembly method is to use the shaft and gear as components. After disassembling together, align the punch with the elastic pin by hand, and use a hammer to remove the elastic pin. Pin out. With this disassembly method, the human hand is easily injured, and the disassembly efficiency is low.
