Fasteners are a class of mechanical parts that are widely used for fastening connections. In a variety of machinery, equipment, vehicles, ships, railroads, bridges, buildings, structures, tools, instruments, meters and supplies, etc., can be seen above a variety of fasteners. It is characterized by a wide variety of specifications, performance and use of different, and standardization, serialization, generalization of the kind of degree is also very high.
fasteners commonly used testing equipment
Fastener development and design is the most important part of the quality control, from the feed to the finished product shipments have several major gates, these major gates have different inspection methods. First of all, the incoming material is related to the appearance, size, elements, performance, harmful substances testing, etc.; the process is more appearance, size, knocking test, forging line; heat treatment is more appearance, hardness, torque, tensile, metallurgical, etc.; the surface treatment is more hydrogen embrittlement test, plating, salt spray, etc., including the shipment of a harmful substances testing. In the size, appearance testing, the common is the secondary element, contour measuring machine, three coordinate measuring machine, image sorting machine; mechanical and chemical testing, mainly hardness machine, tensile machine, metallurgical microscope; material testing, there is a spectral analyzer, salt spray testing machine.
it usually includes the following 8 types of parts:
1. bolts: 2. studs: 3. nuts: 4. wood screws: 5. Washers: 6. Retaining ring: 7. Pins: 8.Rivets:
