STSEP Type Servo Elbow Link-Style High Precision Coining Press Price

Advantages

Direct drive via servo motor, providing stamping energy in place of the flywheel for the press, eliminating clutches and brakes.

Fewer mechanical parts, less inertia of the transmission structure, lower noise level, simplified maintenance, and cheaper maintenance costs.

Precise control of the stamping process by arbitrarily setting and adjusting the servo motor speed.

Optimized stamping process curve by arbitrarily programming the operating speed, stroke position and pressure of the slide, greatly improving the accessibility and flexibility of production.

Full load operation while stamping at low slide speed (above 1 spm).

Reduced press working cycle time, enhanced production rate and production efficiency by increasing the speed of slide's return stroke.

Improvement of the accuracy and quality of stamped parts, minimization of the impact on the dies, extension of the dies' life time cycle, and reduction of the cost through utilization of low stamping stroke speed.

Efficient drive solution to reduce energy consumption.

Comprehensive energy management system, recycling of excess energy, and controlling instantaneous energy release during stamping.

Handwheel fine-tuning function, significantly reducing the time of tryout.

Same safety and logic control as mechanical press.

Components/Functions

Main motor is Low Speed High Torque Servo Motor. Brand: S-T Intelligence.

Servo Drive & Control System, Brand: S-T Intelligence.

Slide pneumatic-hydraulic overload protection: slide stops automatically when the load is 10% more than the nominal capacity.

Overload reset time (after the slide stops at TDC) <180 seconds.

Manual blown-off can be carried out when the mode switch is at "test" position.

Eight-points square guides for slide. Super-long guiding. Perpendicularity between the slide movement and bolster top has been kept.

Electrical die height adjustment device. Adjusted only at normal counterbalance pressure, hydraulic protection and lubrication.

Automatic stop at upper and lower adjustment limit.

Manual adjustment by functional keys / hand wheel. Automatic adjustment by preset value.

Counterbalance Pressure to be adjusted manually / automatically, interlocking with adjustment motor of slide and the control of servo motor.

The frame is of welded structure with stress-relief.

The welding groove form and weld selection meet the standards, and CO2 gas shielded welding is used. Special inspections such as non-destructive testing are carried out on key welds.

After welding, the press machine body undergoes treatment to eliminate internal stress. Eliminating the deformation of components and instability in the overall geometric accuracy of the press structure caused by stress release after long-term operation of the press.

To ensure the accuracy and reliability of the dimensions of large parts such as the machine body, all welding of large parts is completed on the boring and milling machining center, with one clamping to ensure the geometric accuracy of the press.
