(Summary description)Test items: Screw component analysis, screw torque test, screw hardness test, etc. Please contact Ms. Chen for details extend: The influence of various elements in the material on the properties of steel: 1. Carbon (C): To supplement the strength of steel parts, especially its heat treatment function, but with the addition of carbon content, plasticity and resistance decrease, and will affect the cold heading function and welding function of steel parts. 2. Manganese (Mn): To supplement the strength of steel parts and to supplement the hardenability to a certain extent. That is, the strength of hardening is added during quenching, and manganese can also improve the surface quality, but too much manganese will hinder the ductility and weldability, and will affect the manipulation of the coating during electroplating. 3. Nickel (Ni): To supplement the strength of steel parts, improve resistance at low temperatures, improve atmospheric corrosion resistance, and ensure a stable heat treatment effect and reduce the effect of crispness. 4. Chromium (Cr): can supplement hardenability, improve wear resistance, supplement corrosion resistance, and help maintain strength at high temperatures. 5. Molybdenum (Mo): It can assist in the control of hardenability, reduce the sensitivity of steel to temper brittleness, and have a great influence on the tensile strength under tonic high temperature. 6. Boron (B): can supplement the hardenability, and help to make the low carbon steel have the expected response to the heat treatment. 7. Alum (V): Refine austenite grains and improve resistance. 8. Silicon (Si): to ensure the strength of steel parts, and the proper content can improve the plasticity and resistance of steel parts.

Hardware common sense: screw strength torsion test

Screw strength test: 1. Turning force test: The twisting force of a product shows its ability to resist being twisted in half. Various standards have minimum requirements for the torsion force of self-tapping screws. In this test, the screw is clamped in a chuck with a tapped middle part on the torsion test tool, and then a torque wrench is used to apply force until the screw is twisted. If the torque does not exceed the minimum requirement, the product is unqualified. Unqualified indicates that the screw is too soft or the thread diameter is too small. 2. Locking test: This test is to lock the screw to a test board, this board has the specified hardness, thickness and aperture. If the screw is locked through the test board, but the thread is deformed, the product is not qualified. Unqualified indicates that the surface hardening treatment of the screw is too shallow or too soft. 3. Locking torque test: This test is only required for the screw rolled by the screw. When the lock test is performed, the minimum lock torque of the test board is observed. If the torque exceeds the specified standard value (the standard value is based on the size of the screw and the surface treatment), the product is not qualified. Unqualified shows that the surface of the screw does not have enough lubricity, or the thread is formed improperly and requires more torque.

Basic knowledge of Phillips screwdriver specification selection

Phillips screwdrivers generally have 7 specifications from small to largest ph000 ph00 ph0 ph1 ph2 ph3 ph4 The approximate relationship between the diameter of the screwdriver shaft and the specifications: 4mm~4.5mm rods generally do cross Ph1, which can cover ph000 ph00 ph0 ph1 This series is basically a precision series, disassembly and assembly of small electronic devices, glasses, watches, radios, tape recorders, etc.. Must! This is mainly a set, of which ph000 is very small, not a lot of use The 6mm rod is generally used for the Phillips Ph2 specification. This is the most commonly used specification in the medium-sized screwdriver, so you can buy one separately and use it for the fastening screws of the display, radio, TV and other housings, transformer fixing, etc. It is also a Ph2 head that makes furniture door screws. The 8mm rod is used for Ph3, and the 10mm rod is used for Ph4. Basically, it may be used in mechanical equipment. It is rarely used in electronic assembly, unless it is used as an electric box controller... So the combination scheme of Phillips screwdriver configuration is roughly: Precision screwdriver set below 4mm rod + a separate Ph2 screwdriver If you consider that the handle of the suit is too thin to focus on, you can also configure a Ph1 screwdriver separately. It is not a problem if it is not configured. Nothing is too particular about a word There are many types of star batches, and the general suits start from T6, but some modern mobile phones have the smallest use of T5, so generally suit + T5 can hit the world. About the material experience: From lowest to highest Medium carbon steel-high carbon steel-crv- S2- S2 plus titanium oxide coating-S2 plus diamond coating. For example, wera's most high-end Beatles can increase friction after using diamond coating without increasing the force or slipping screws.
