Service HotlineThe advantages of the pressure riveting nut: 1. The length guarantee of the distance range is realized, which greatly simplifies the assembly process and speeds up the production progress of the assembled spacing panel and accessories; 2. The back of the plate is completely embedded and flat, while ensuring the head of the nut column The plane is smooth with the plate; 3. The raw material is free-cutting iron or free-cutting stainless steel; the technical guide for the application of the pressure riveting standoff: 1. When selecting the standoff, it must be based on the thickness of the plate used, the exact size range, and the hardness of the low-carbon steel plate must be less than 70RB, the hardness of stainless steel plate must be less than 80RB. 2. The surface of free-cutting iron is treated, and the stainless steel maintains its original color. Users can order according to the model and specifications in the table according to their needs, or they can also make special orders according to their needs. 3. The hole size of the plate must be processed according to the tolerance size of 0-+0.075mm, and punching is recommended. 4. The installation must be realized by press riveting operation, and it must not be knocked in by impact. 5. When the material is stainless steel, the tail number should be marked with S. 6. The end face of the nut column is represented by C. 7. The length of the through-hole nut column is full wire below 10mm. If it is above 10mm, it can be reamed on the hexagonal end face (type I) or the round end face (type II).
Guangdong Yueluo Hardware Industry Co., Ltd. relates to a connecting piece, especially a wood screw used for fixing on non-rigid materials such as wood or plastic. Guangdong Yueluo Hardware Industry Co., Ltd. has a threaded part with a taper angle and a screw head. The head of the screw can be countersunk, hemispherical, or other shapes. As for the grooves for screwing, the grooves can be straight-line grooves, concave cross grooves, or grooves of other shapes.
At present, shaft retaining rings are mainly divided into three categories: elastic retaining rings for shafts, flattened wire retaining rings for shafts, and wire retaining rings for shafts. Among them, the spring retaining ring for the shaft is generally installed with circlip pliers, and the flattening wire retaining ring for the shaft and the wire retaining ring for the shaft are generally installed with a sharp screwdriver or needle-nose pliers. The defects and deficiencies of these two methods will be discussed in detail below: First, the above two installation methods require the operator to use a large force to open the retaining ring, which is more laborious; For the installation of the flattened steel wire retaining ring for the shaft and the steel wire retaining ring for the shaft, because the wire retaining ring has low elasticity and has no force point, it is very easy to cause the retaining ring to break or the installation tool to slip during the installation process. Higher skills and experience can be competent for the installation of wire retaining rings.
For a long time, the rivets used in general riveting, especially the ordinary rivets and bolts and other fasteners commonly used in steel structures such as vehicles and bridges, have low connection reliability, especially under alternating load and impact conditions. Looseness is easy to occur, the maintenance cycle is short, and the maintenance cost is high in the later period, which cannot meet the requirements of railway freight.
At present, the installation methods of the retaining ring: 1. Most of them are installed with retaining ring installation pliers; 2. Simple installation aids; 3. Automatic retaining ring installation machine. The disadvantages of these installation methods: 1. If the manual installation is uneven, the elastic retaining ring will deform plastically, which will cause the elastic retaining ring to fail; 2. It cannot be positioned for complex structural parts, and the production efficiency is also low; 3. Simple installation Auxiliary tools are only suitable for the parts to be installed, which are generally not universal and have limitations; 4. The automatic elastic retaining ring installation machine has a complex structure and high cost.
