Automatic Blank Feederfor Stamping Press
Henli automatic blank feeder uses vacuum suction loading, dual-servo precision push-feed, Mitsubishi PLC control, and rear roller ejection to automate pre-cut sheet feeding before the stamping press.
- For blank-fed production: picks one pre-cut blank from the stack and transfers it into the die area.
- For high-volume output: supports 35-60 SPM production according to blank size, tooling, and press timing.
- For stable feeding: dual-servo push feed and PLC control help keep blank positioning consistent during continuous runs.
From Stacked Blanks to Stamped Parts With Less Manual Handling
This system is for factories that already use pre-cut blanks and need a compact automation unit to load, position, feed, and discharge material around a stamping press.
What the system does
The automatic blank feeder is engineered for high-efficiency, stable automated production. It works with the stamping press to reduce manual loading, improve feed rhythm, and support continuous production for pre-cut sheet blanks.
Pick
Vacuum suction cups pick a single sheet from the blank stack.
Feed
Dual-servo push feed positions the blank inside the press die.
Eject
Rear roller handling clears the finished part or scrap skeleton.
Choose Blank Feeding When the Material Is Already Cut to Sheet Size
Blank feeders and coil feeders solve different production problems. Use this page when the press line starts from stacked blanks, not from coil strip.
Use this blank feeder
For pre-cut blanks, stacked sheets, small-to-medium blank sizes, and press lines where the blank must be picked, placed, pushed into the die, and ejected after stamping.
Use a coil feeder instead
If the line starts from coil material and needs decoiling, straightening, loop control, and roll feeding, review NC servo feeder or complete coil feeding line options.
Send blank data first
Blank size, thickness, material, stack height, surface condition, press speed, die layout, and discharge method decide whether the standard configuration is suitable.
Why This Blank Feeding System Improves Stamping Efficiency
The value is concentrated in stable control components, automated blank transfer, high-speed feeding, and simple operator adjustment.
Premium Core Components
Delta servo motors and Mitsubishi PLC control provide a practical control foundation for repeated blank loading and feeding cycles.
Fully Automated Workflow
Vacuum suction loading, dual-servo in-mold feeding, and automatic roller ejection reduce manual intervention during continuous production.
High-Speed Production
35-60 SPM reference production speed helps meet high-volume stamping demand when blank size, tooling, and press timing allow it.
Dual-Servo Precision Feeding
The servo push-feed system helps place each blank into the die area with repeatable motion and controlled feed rhythm.
Material Compatibility
Suitable for metal or non-metal blanks within the machine width, length, and thickness reference range after checking the blank data.
User-Friendly HMI
Operators can set feeding parameters through the HMI, making routine adjustment and changeover easier for the production team.
Blank Feeding Process: Loading, Picking, Feeding, Stamping, and Ejection
The system is designed for a smooth, repeatable production cycle around the stamping press.
Loading & Stacking
Operators place a stack of pre-cut blanks onto the storage or loading area.
Vacuum Pick & Place
The suction cup gantry picks one sheet and places it onto the feeding table.
Precision Servo Feed
The dual-servo push-feed system advances the blank into the die according to preset parameters.
Continuous Operation
While one blank is stamped, the next blank can be prepared for the following cycle.
Scrap / Part Ejection
A rear-mounted roller system transports finished parts or scrap skeletons out of the work area.
Automatic Blank Feeder Specification Reference
Use these values as a starting point. For unusual blank size, material, stack height, surface condition, or press timing, Henli can customize the system after engineering review.
| Feature | Parameter | Buyer note |
|---|---|---|
| Control System | Mitsubishi PLC | Confirm signal interface with the stamping press. |
| Drive System | Delta Servo Motor | Used for controlled push-feed motion. |
| Power | 2 kW | Final electrical configuration depends on local requirements. |
| Production Speed | 35-60 SPM (strokes per minute) | Depends on blank size, tooling, press timing, and line layout. |
| Applicable Material Width | 0-300 mm | Non-standard width should be checked before quotation. |
| Applicable Material Length | 0-1200 mm | Long blanks may need custom feed stroke or support. |
| Applicable Material Thickness | 0.2-3.0 mm | Material type and surface condition affect separation. |
| Loading Method | Automatic vacuum suction loading | Tell Henli whether one blank or special separation is required. |
| Feeding Method | Dual-servo precision push-feed | Feed direction, press opening, and die position should be reviewed. |
| Scrap / Part Handling | Rear roller ejection | Share whether finished parts or scrap skeletons need discharge. |
Suitable for High-Volume Blank Stamping Automation
This system is a practical automation solution for blank-fed stamping processes across multiple industries.
Automatic Blank Feeder in Real Stamping Production
The video demonstrates how vacuum suction picks a single sheet from the stack and how dual-servo feeding pushes it into the press with stable, repeatable motion.
- Sheet separation: watch whether the suction system picks one blank cleanly.
- Feed stability: watch how the servo push feed enters the die area.
- Line rhythm: check whether loading, feeding, stamping, and ejection stay synchronized.
