Difficult to penetrate, or the problem that the anti-rust oil cannot penetrate due to the tight contact between the screw thread and the thread groove. In terms of material saving, the traditional anti-rust of screws often causes a lot of waste of anti-rust agent, and cannot achieve a good anti-rust effect of screws.
Further, the clamping mechanism includes two clamping plates placed between the two fixing blocks, a bearing seat is installed on one side of each of the clamping plates, a bearing is installed inside the bearing seat, and the bearing is The inner ring is snap-connected with an elastic adjustment screw, and the other end of the elastic adjustment screw penetrates the fixing block and is placed outside the fixing block.
The flat key is simple in manufacture, reliable in operation, convenient in assembly and disassembly, and widely used. The flat key transmits torque by contacting the two sides of the keyway with the two sides, that is, the side is the working surface, so the main technical requirements for assembly are: to ensure the matching requirements between the flat key and the keyway of the parts on the shaft, and to transmit the movement smoothly and torque. The matching nature of the key and the keyway generally depends on the working requirements of the mechanism. The key can be fixed on the shaft or the hub, and can slide relative to another matching part (guide flat key); it can also be fixed on the shaft and the hub at the same time (ordinary flat key), and based on the size of the key, by changing the shaft The size of keyway and hub keyway can meet different matching requirements.
The types of rivets can be roughly divided into open type, closed type, double drum type and single drum type series. The following is a brief description of their respective models. Countersunk head blind rivets: For the riveting of riveting parts that require smooth and beautiful surfaces after riveting. Double-drum blind rivet: During riveting, the mandrel pulls the end of the rivet body into a double-drum shape, clamps the two structural parts to be riveted, and can reduce the pressure acting on the surface of the structural parts. Uses: Mainly used for riveting various thin structural parts in various vehicles, ships, construction, machinery, electronics and other industries. Blind rivet with large brim: Compared with ordinary blind rivets, the diameter of the aluminum cap of this rivet is significantly larger. When the rivet is riveted with the connector, it has a larger contact area and a stronger supporting surface, which can enhance the torque Strength, can withstand higher radial tension. Applicable industry: It is suitable for fastening soft and fragile surface materials and extra-large holes. The increased diameter of the brim has special protection applications for soft materials. Closed Blind Rivet: Designed to wrap around the mandrel head after riveting, ideal for many applications where waterproofing is required. With high shear force, anti-vibration, anti-high pressure.
304L stainless steel cold pier line, 304 stainless steel cold pier line, 310 stainless steel cold pier line, 303 stainless steel cold pier line, 302 stainless steel cold pier line, 301 stainless steel cold pier line, 202 stainless steel cold pier line, 201 stainless steel cold pier line, 410 stainless steel Cold pier line, 420 stainless steel cold pier line, 430 stainless steel cold pier line, 316L stainless steel cold pier line: 316 stainless steel contains molybdenum and low carbon content, and its resistance to pitting corrosion in marine and chemical industry environments is much better than 304 Stainless steel! (316L low carbon, 316N nitrogen high strength and high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel [1]. 304L stainless steel cold pier wire: as a low carbon 304 steel, in general, the corrosion resistance is the same as 304. Similar, but after welding or after stress relief, its resistance to grain boundary corrosion is excellent, and it can maintain good corrosion resistance without heat treatment. 304 stainless steel cold pier wire: has good corrosion resistance, heat resistance High temperature resistance, low temperature strength and mechanical properties, good thermal processability such as stamping and bending, no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (use temperature -196°C-700° C) 310 stainless steel cold pier wire: The main features are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are average. 303 stainless steel cold pier wire: By adding a small amount of sulfur and phosphorus, it is easier to cut than 304, Other properties are similar to 304. 302 stainless steel cold pier wire: 302 stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. The details are as follows: handicrafts, bearings, slippery, medical equipment, electrical appliances, etc. Features: 302 stainless steel The ball is austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good rust and corrosion resistance. 301 stainless steel cold pier wire: good ductility, used for forming products. Machining makes it harden quickly. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel. 202 stainless steel cold pier wire: belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel cold pier wire Shenzhen Global Stainless Steel Cold Pier Wire 201 Stainless Steel Cold Pier Wire: It belongs to chromium-nickel-manganese austenitic stainless steel, with low magnetic properties. 410 stainless steel cold pier wire: belongs to martensitic (high-strength chromium steel), with good wear resistance and corrosion resistance Poor performance. 420 stainless steel cold pier wire: cutting tool grade martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. It is also used for surgical knives and can be made very bright. 430 stainless steel cold pier wire: Ferritic stainless steel, decorative, e.g. for car accessories. Good formability, but poor temperature and corrosion resistance
