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.

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.
