Straight Side Servo Press (STP series)
Main performance characteristics:
The fuselage has ultra-high rigidity (deformation) 1/15000, small deformation, long accuracy retention time, high precision of stamping products, small forming rebound, and can carry large eccentric loads.
Use pneumatic wet clutch brake, environmental protection, no pollution, low noise, long service life.
The slider adopts four-corner and eight-sided guide path, which can carry a large eccentric load: to ensure the long-term and stable maintenance of stamping accuracy.
Slider guide rail adopts "high-frequency quenching" and "rail grinding process", with little wear, high precision, long precision retention time, and improved mold life.
Forced thin oil circulation lubrication device is adopted, which is energy-saving, environmentally friendly, and has an automatic alarm function. The number of stamping can be increased by adjusting the amount of oil.
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.
The copper sleeve is made of tin-phosphorus bronze ZQSn10-1, whose strength is 1.5 times higher than that of ordinary BC6 brass. It adopts a highly sensitive hydraulic overload protection device, which can effectively protect the service life of the punch and die.
Standard imported 4-channel tonnage sensor can detect (display) the tonnage of the product stamped in real time, and the punch will automatically stop if it exceeds the tonnage to protect the punch and mold.
Standard Japanese SMC pressure regulating valve, lubricator, air filter.
Standard Japanese NSK bearings and Japanese NOK seals.
Standard configuration of German Siemens PLC, Siemens touch screen, Siemens motor, German SICK four-level grating, SICK encoder.

DAYA straight side double crank punch press
VS
Other straight side double crank presses
Daya press
Daya press: with platform and safety fence, convenient for clutch maintenance and change of cooling oil, main motor belt is loose and easy to adjust, and convenient for subsequent maintenance. Safer and more convenient.
Other press
Other press: Without maintenance platform. Clutch maintenance, replacement of cooling oil, loose adjustment of main motor belt, etc. which can only be completed with the assistance of forklift, which is not convenient for subsequent repair and maintenance. There are some potential safety hazards.
Daya press
Daya press: Daya press adopts four corners and eight sides to surround the guide rail. In the stamping forming position, the slide guide rail is included by all the guide rails on the table body. This kind of guide rail has the characteristics of high stamping accuracy, strong anti eccentric load capacity, small rail wear and long precision retention time.
Other press
Other press: the guide rail with semi enclosed structure as shown in the right figure is adopted. During the stamping process, there is a section of guide rail exposed. During the stamping process, the slide guide rail is easy to tilt, with poor anti bias load capacity, large rail wear, short precision retention time and high maintenance cost.
Daya press
Daya press: the distance between the two points of force application is more than 60%; Advantages: the larger the distance between the two force application points, the greater the eccentric bearing capacity; the larger the distance between the two force application points, the higher the design cost.
