Product Description

 

Product Description

C-Frame Double Crank Presses from 80 to 315 Tons Mechanic Press

STC series press is two points gap frame press,double crank unitized frame with long bed area, great for light duty progressive die application or large single stroke parts.

STC series presses are produce by Qiaosen presses,which built to meet or exceed JIS Class 1 accuracy standards . Qiaosen adopt high strength steel frames and Quenching&Grinding Process for Slide-Guide,which can make the press machine have minimizing deflection and high accuracy and provide increased tool life.

 Forged 42CrMo alloy meaterial crankshaft ,precision-machined gears and other drive train components are designed for smooth power transmission, quiet operation and long life. ST series presses are dry clutch system,It has longer service life of the clutch system ,high single stroke rate and high torque outputs performance.

Siemens based control platform and user-friendly touch screen operation interface are standardized in all QIAOSEN's presses, it provides ease of operation and expandable capabilities.Easy to integration with other automation system. Other brands of control can be furnished upon request.

Our Advantages

High strength steel frames
with small deformation

Slide rail adopt high frequency quenching technology,
its hardness could reach  HRC45 degree or more.
Advantage: perfect wear resistance

The gear shaft is made of high-strength alloy,
all tooth surfaces are treated with medium frequency
Advantage: small wear, high accuracy,long service life

Crankshaft
Alloy 42 CrMo Material
Advantage:  1.3 times Stronger than 45 steel

Ball Seat
Japanese grade TM-3 sintered copper alloy
Advantage: less failure rate with sawtooth ball

Features

1. The press frame is composed of three parts (cover, middle platform body, and base), and finally connected with a reinforcing rod to form a solid lock.
2. The frame and slider have high rigidity (deformation) of 1/9000: small deformation and long accuracy retention time.
3. Presses below 600 tons use pneumatic wet clutch brakes (unibody), while presses above 800 tons use dry clutch brakes (split-type).
4. The slider adopts 8-points slide guiding, which can bear large eccentric loads, ensuring long-term and stable maintenance of stamping accuracy.
5. The slide rail adopts the "high-frequency quenching" and "rail grinding process": low wear, high precision, long accuracy retention time, and improved mold service life.
6. Adopting a forced thin oil circulation lubrication device: energy-saving, environmentally friendly, equipped with automatic alarm function, which can increase the stamping frequency by adjusting the oil volume.
7. The crankshaft is made of high-strength alloy material 42CrMo, which is 1.3 times stronger than 45 steel and has a longer service life.
8. The copper sleeve adopts tin phosphorus bronze ZQSn10-1, which has a strength 1.5 times higher than ordinary BC6 brass. It adopts a highly sensitive hydraulic overload protection device, which can effectively protect the service life of the punching machine and mold.
9. Standard Japanese SMC pressure regulating valve, oil mist filter, and air filter.
10. Standard configuration: German Siemens touch screen and Siemens motor.
11. Optional die cushion.
12. Optional Moving bolster
