JH21 single crank sheet metal stamping power press machine
priceOpen Back Press with Fixed Bed, a kind of thin sheet metal
processing universal press imported advanced technology of
AIDA company in Japan, which is suitable for shearing, punching,
blanking, bending and shallow drawing. The structural feature is as
follows:I. Brief introduction of structure1,The frame is welding
with whole steel plate which has high rigidity, reasonable
structure and beautiful design.2,The press adopts the vertical
crankshaft structure. The distance of fulcrum is short and the
crank is rigid.Driving gear is installed into the frame and
gear is immersed in oil reservoir. Customer could choose
Electromagnetic governor(Wannan motor factory), which is stepless
speed regulation within a certain range and enlarge the area of
craft. 3,The press adopts Italy low inertia combined
wet friction clutch and brake made in Shanghai
OMPI, which has little passive inertia, low energy
consumption, reliable interlock of clutch and brake and long
longevity.4,The slide is a whole cast form construction which
adopts hydraulic overload protector made in Showa, Japan with
agile and reliable action. After overload, it can reset
automatically to reduce the down time and improve the availability
of press. High pressure oil seal which is imported from German is
installed in slide high pressure cylinder.5,The shut height adopts
electric adjustment, which has digital display. Its display is
0.10mm. The press adopts hexahedral rectangle lengthen gib, which
has high guiding precision and steady precision.The press has
pneumatic balancer, which reduce the second stroke. It runs
smoothly to improve the dynamic precision of press.6,The control
part adopts PLC from Mitsubishi, which is efficient to guarantee
the reliability of control part.7,The press adopts dual valve from
TACO, Japan, which can guarantee the safety and reliability of
clutch.8,The press adopts cam controller which be combined with
proximity switch. It can send signal exactly within the range of
360°and control the criterion of various actions and the harmony of
assist machine to improve the reliability of press. Besides,
the press has two-hand operating button and foot pedal switch,
which can realize Continuous, Single and Inch mode. II.Guideline of
Technical performanceThe model JH21-315 press is manufactured
according with accuracy of open press (JB/T 6580-93) and technical
requirement of open press (JB/T 6580.1-1998). The security is
according with the security and technical terms standard of forging
machinery (GB17120-1997) and the security and technical requirement
standard of mechanical press (JB3350-93). III.Main Technical
