Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a fastener with a new structure with a nut, which cannot be tightened by conventional tools during use, and is suitable for special occasions requiring anti-theft.
Stainless steel screw wire is also called stainless steel cold pier wire, which is mainly used for various fasteners, such as mechanical parts, electronic application parts, etc. Corresponding anti-corrosion properties and mechanical properties can be obtained according to different materials. In order to obtain a better formability during cold forging, choose high quality. The appropriate material of the wire is particularly important.
Rivets are mostly used for fixed riveting and movable riveting between parts. The rivets used for movable riveting are mostly cylindrical, and there is no size limit for riveted parts, which is easy to cause parts to be squeezed and deformed during riveting. For example, The parts are inserted into the parts for active riveting. When riveting, the riveting force can easily cause the parts to clamp the parts, which in turn causes difficulty in the movement of the parts and the parts, high operating force and noise problems, and the parts are easily damaged.
The circlip travel mechanism includes a travel cylinder and a travel plate connected with the push rod of the travel cylinder; the travel air cylinder can control the travel plate to be inserted into the circlip press-out and positioning mechanism, and the circlip lifting and tightening mechanism; the travel plate The surface of the device is provided with a groove for placing the circlip; the height of the groove is the height of one circlip.
Anti-corrosion technology Stainless steel screws are made of metal, and there are four main methods for metal anti-corrosion, namely the properties of the material itself, the environment of use, the interface between materials and the environment, and the improvement of the metal structure design. If a complete anti-corrosion alloy is used to make stainless steel Screws, unless there is a special need, are not cost-effective in terms of economics, and it is also impractical to completely isolate the appearance of the screw from environmental elements that can cause corrosion. Improving the metal structure design can improve the influence of special circumstances under certain conditions, but the design of most stainless steel screws cannot be fully corrected, and its maintenance effect is not permanent, so this method cannot basically solve the problem, as long as it is on the surface. Top anti-corrosion, that is, surface anti-corrosion treatment is the most widely used method. The anti-corrosion treatment on the surface of stainless steel screws refers to the use of various methods to apply a protective layer on the metal surface. The purpose of avoiding or mitigating corrosion. The protection layer should be able to meet the following requirements: 1. Corrosion resistance, wear resistance, high hardness, 2. The structure is tight, intact, and the pores are small. 3. It has strong separation and good adhesion with the base metal. 4. It is evenly distributed and has a certain thickness. The maintenance layer is usually divided into two types: metal coating and non-metallic coating. Metal coating refers to the use of metal or alloy with strong corrosion resistance to form a maintenance layer on the surface of metal that is easy to corrode. This coating is also called plating. There are quite a few methods and varieties to produce metal coatings, the most common of which is electroplating, followed by molten metal immersion plating (hot dipping) and chemical surface treatment. Non-metallic coating refers to the use of organic polymer materials such as paint and inorganic materials such as ceramics to form a protective layer on the surface of metal equipment or parts. The protective layer can completely isolate the base metal from the environmental medium and prevent the base metal from corrosion due to contact. Corrosion is formed in the medium of stainless steel standard parts.
