Hardware stamping parts, hardware shrapnel is a kind of commodity we use more. This is an important component of the power switch, by virtue of the metal material shrapnel conduction characteristics, between the operator and the product to play a high quality switch role.
Hardware shrapnel generally according to the use and characteristics of the shrapnel to determine the material, such as the use of physical resilience is relatively high, the working pressure is relatively large, is generally selected to tool steel, carbon steel or high toughness stainless steel plate, forming after quenching heat treatment, reduce the carbon content, according to improve the strength to improve the light life of the shrapnel; If you need to make it conducive to electric welding, corrosion resistance, improve electrical conductivity and other process performance, choose copper material to produce and process shrapnel, such as phosphorous copper strip shrapnel, tin bronze shrapnel, can be through plating process (gold, silver, nickel, tin, etc.) surface treatment method to meet the requirements; Secondly, for electronic communication and other digital technology products, the key process functions are mainly reflected in precision, conductivity and weldability. Therefore, the selection of copper materials to produce and process shrapnel products is generally a specific application of a fixed type/strength of copper materials, such as phosphorous copper strip, tin bronze, red copper, copper, brass, etc.
What are the basic functions of hardware shrapnel?
(1) Operate mechanical fitness exercises, such as valve springs in gas turbines, clutch control shrapnel, etc.
(2) Digestion and absorption of shock and impact energy, such as the cache shrapnel under vehicles and high-speed rail cars, and the vibration absorbing shrapnel in the connecting shaft, etc.
(3) Store and export kinetic energy as a driving force, such as clock shrapnel, gun shrapnel, etc.
(4) As a dynamometer component, such as force gauge, shrapnel balance in the shrapnel, etc. The ratio of the load to the deformation of the shrapnel is called the bending stiffness of the shrapnel. The more the bending stiffness, the harder the shrapnel. According to the supporting characteristics, the shrapnel can be divided into Rashen shrapnel, reduced shrapnel, twisted shrapnel and bending shrapnel, according to the appearance can be divided into plate shrapnel, ring shrapnel, plate shrapnel, spiral shrapnel, frustum torsion spring shrapnel and its torsion bar shrapnel.
