Custom-made processing according to sample Small MOQ hinge pin with eco-friendly material for automatic package machine

Hinge pin

is a kind of standardized fasteners, which can be static fixed connection, can also be connected with the relative movement, mainly used for the hinge of two parts, usually form hinge pin lock with cotter pin, reliable work, easy to disassemble.

Commonly used material

40 cr

40Cr is a commonly used material for shaft parts, it is cheap after quenching and tempering (or normalizing), can get better cutting performance, and can get higher strength and toughness and other comprehensive mechanical properties, after quenching surface hardness up to 45 ~ 52HRC.

40Cr and other alloy structural steel is suitable for shaft parts with medium accuracy and high rotating speed. After quenching and tempering, this kind of steel has better comprehensive mechanical properties.

40Cr steel is one of the most widely used steels in the machinery industry.After tempering and tempering treatment, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.Good steel hardenability, when water quench hardening to Ф 28 ~ 60 mm, when oil quenching hardening to Ф 15 ~ 40 mm.This steel is suitable for cyanidation and high frequency quenching in addition to quenching and tempering.When the hardness is HB174 ~ 229, the relative machinability is 60%.

30 CrMnTi

Compared with 20CrMnTi steel, the strength and hardenability are higher, but the impact toughness is lower.Mainly used for carburizing steel, after carburizing can be directly cooled quenching, bending strength is high, good wear resistance.It can be used after quenching and tempering at low temperature or quenching and tempering with medium machinability.Used for manufacturing the heavy load carburized parts with large section in tractor industry and the gear, gear shaft and worm with large force.

Precision Pivot Pin with Keyway

Pin shaft is a kind of standardized fasteners, which can be static fixed connection, can also be connected with the relative movement, mainly used for two parts of the hinge, forming a hinge connection.Pin shaft is usually locked with cotter pin, reliable work, easy to remove.The international standard for pin shaft is ISO 2341:1986.
