Service HotlineRivets are widely used in the fixing of product components, and the process of inserting rivets into products is currently mostly done by manpower. However, relying on manpower to insert rivets has low automation and low efficiency, which is not conducive to large-scale Production.
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.
In the household and industry, when installing furniture, home appliances, electrical appliances, equipment and other objects, the objects are uneven or uneven due to the uneven bottom of the object, or because the placement surface or installation surface is uneven, or because the two surfaces are different and do not fit together. stable, produce vibration, shaking or sliding, affecting the use effect and service life. Sometimes two items need to be placed next to each other, but their surfaces cannot be in direct contact, otherwise the surfaces will be damaged. For these two cases, the common solution is to install gaskets. There are two types of gaskets: wedge and flat. The wedge-shaped gasket adjusts the actual thickness by adjusting the length of the insertion gap, but the contact surface and load-bearing surface of this method are small, and due to its wedge-shaped structure, the gasket may withdraw after being stressed for a long time. Flat gaskets are generally made from local materials, using waste paper, plastic, rubber, metal and other materials to form the required thickness by folding or stacking. Such gaskets are often not quickly assembled to the exact desired thickness, are not aesthetically pleasing, and are not reusable. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a product that can keep furniture, home appliances, equipment, electrical appliances and other objects horizontal, vertical or stable, prevent them from vibrating, shaking or sliding, and can provide appropriate thickness and beautiful appearance. gasket. The purpose of Yueluo is to realize a gasket that can be combined at will. The sheet 1 is provided with small holes 3 , and the connecting device 2 connects a plurality of sheets 1 together through the small holes 3 . The connecting device 2 is a rivet or a screw. The material of the sheet 1 can be plastic, metal, paper card or rubber. The gaskets provided by Yueluo can be combined at will. Multiple sheets are connected together by rivets or screws. By opening or closing the sheets, or dismantling the screws, the sheets are reassembled to obtain a combination of gaskets with different thicknesses and elasticity. The space between the installation object and the installation surface to keep the object horizontal, vertical or stable and prevent it from vibrating, shaking or sliding.
Wood screws, one of which is a polished rod, the angle and pitch of the teeth of the wood screws and self-tapping are different. Self-tapping screws have high hardness, wide thread spacing, deep threads, and uneven surface, while wood screws are the opposite. Another difference is more obvious. Wood screws have no threads at the rear. Self-tapping screws are generally subject to heat treatment, and wood screws are not required. The concept of self-tapping screws is actually very general, because there are many kinds of them according to different head types. Use of wood screws: Similar to machine screws, but the thread on the screw is a special rib for wood screws, which can be directly screwed into wooden components (or parts).
The two combination screws are classified according to the national standard, including GB9074.2, GB9074.3, GB9074.5, etc. GB9074.3 refers to a two-component combination of a cross pan head screw and a foreign lock washer.
