JESENTECH

is a fastener manufacturer that produces and processes non-standard shaped shafts. The hinge pins produced by our company are produced according to the drawings or samples according to the needs of customers;Really realize the material on-demand customization, product shape design is customized according to customer needs, surface treatment is customized according to customer needs;Customers only need to provide professional tolerance design drawings or samples, we can precisely process the products according to all the customer's dimensional tolerances and precision.Our materials are all environmental protection materials, and we can provide material report, SGS report, shipment inspection report and other certificates.

The pin is a type of standardized fastener that can be statically fixed or moved relative to the connected piece, and is mainly used for the hinge of the two parts to form a hinge connection. The pin is usually locked with a split pin for reliable operation and easy disassembly. The international standard for pins is ISO 2341:1986. Domestic standard GB/T882-2008.

The function of the pin is to locate and tighten the parts;It has two types: cylindrical and conical.The installation of the pin generally adopts the method of press-in or soft metal knock in two methods.A conical, pointed, or pointed piece of wood or metal used to fasten or fasten (boards, tiles, soles, uppers, furniture molds, or components) or to mend holes.The pin plays an important role in the connection of mechanical parts.According to the different shapes and functions, can be divided into: cotter pin, taper pin, cylindrical pin, groove pin, etc.In 1986, China adopted ISO fastener product standard for the first time and issued the national standard.Specific can see selling product standard.In the sale product, the cylinder pin, the cone pin and the split pin are the product fasteners which the production USES the quantity to be broad, also is the irreplaceable fasteners product.

Common materials:
1, 45 steel
GB/T699-1999 standard specifies 45 steel tensile strength of 600MPa, yield strength of 355MPa, elongation of 16%, section shrinkage of 40%, impact work of 39J.
45 steel is a common material for shaft parts. It is cheaper and has good cutting performance after quenching and tempering (or normalizing), and it can obtain high mechanical strength such as high strength and toughness. The surface hardness after quenching can be obtained. Up to 45 ~ 52HRC. 40Cr and other alloy structural steels are suitable for shaft parts with medium precision and high speed. These steels have good comprehensive mechanical properties after quenching and quenching.
45 steel is widely used in machinery manufacturing, and the steel has good mechanical properties. But this is a medium carbon steel, the quenching performance is not good, 45 steel can be hardened to HRC42~46. Therefore, if surface hardness is required, and it is desired to exert the superior mechanical properties of 45# steel, the surface of 45# steel is often quenched (high-frequency quenching or direct quenching), so that the required surface hardness can be obtained.
2, 40Cr
40Cr is a common material for shaft parts. It is cheaper and has better cutting performance after quenching and tempering (or normalizing), and it can obtain high mechanical strength such as high strength and toughness. 45 ~ 52HRC.
40Cr and other alloy structural steels are suitable for shaft parts with medium precision and high speed. These steels have good comprehensive mechanical properties after quenching and quenching.
40Cr is the standard steel number of GB in China, and 40Cr steel is one of the most widely used steels in machinery manufacturing. After quenching and tempering treatment, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The steel has good hardenability, and can be hardened to 28 to 60 mm when water quenching, and hardened to 15 to 40 mm when oil quenching. This steel is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering. The cutting performance is good. When the hardness is HB174-229, the relative machinability is 60%.
3, 30CrMnTi
It has higher strength and hardenability than 20CrMnTi steel, but the impact toughness is slightly lower. It is mainly used as carburized steel. After carburizing, it can be directly quenched by cooling, with high bending strength and good wear resistance. It can be used after quenching and low temperature tempering or quenching and tempering, and the machinability is medium. It is used to manufacture heavy-duty carburizing parts with large cross-sections in the tractor industry, as well as gears, gear shafts and worms with large forces.
4, 35CrMnSi
Standard: GB/T 3077-1988
35CrMnSi steel is a low-alloy ultra-high-strength steel. It has good comprehensive mechanical properties after heat treatment, high strength, sufficient toughness, hardenability, weldability, and good formability, but low corrosion resistance and oxidation resistance. It is used after low temperature tempering or austempering.
35CrMnSi steel is a material with good hardenability. After proper heat treatment, the comprehensive mechanical properties of strength, hardness, toughness and fatigue strength can be obtained, which can adapt to the complicated working conditions of coal mining.
