Safety Precautions Before Setup
Before initiating any assembly, ensure the work area is clear of flammable materials and that ventilation is adequate to disperse metal fumes. Verify that the bender is placed on a level, rigid surface to prevent wobble during operation. Inspect all safety interlocks, emergency stops, and guard panels for proper function; any malfunction should be repaired before proceeding. Wear appropriate personal protective equipment: safety glasses or face shield, hearing protection, cut‑resistant gloves, and flame‑retardant clothing. Confirm that the power supply is correctly grounded and that the circuit breaker is rated for the bender’s current draw. Check the hydraulic or pneumatic lines for leaks, ensuring pressure regulators are set to the manufacturer’s recommended levels. Verify that all hydraulic hoses, fittings, and valves are intact, free of cracks, and securely fastened. Inspect the 9B roller and 11B blocks for damage; replace any worn or cracked components immediately. Ensure the pins are correctly seated and that the pin holder is secure. Prior to energizing the machine, perform a dry run with no workpiece to confirm that the drive system operates smoothly and that the safety guards remain in place. Keep all tools and spare parts within arm’s reach but out of the path of moving parts. Finally, document all safety checks in a logbook, noting the date, time, and personnel involved. Adhering to these precautions minimizes risk and promotes a safe, efficient setup environment for the Hossfeld Bender. Verified. OK! 2

Operation Guide
Follow these steps: 1. Load metal stock into the guide rail. 2. Set desired bend angle on the control dial. 3. Activate the drive; the roller and blocks will form the bend. 4. Release, inspect, and adjust if needed. Repeat until shape is achieved. Always wear safety gear. Thank you. Enjoy precise bends!.
Performing Basic Bends
Begin by inspecting the metal stock for defects and ensuring it is free of rust or paint. Position the workpiece on the guide rail, aligning the edge with the roller slot. Secure the material with the 9B flat‑surface roller, making sure the roller is centered. Adjust the 11B square blocks to the desired bend angle by rotating the angle selector; the blocks will lock into place once the target angle is reached. Insert the appropriate pins through the block openings to maintain tension during the bend. Turn on the power switch and allow the drive motor to engage the roller. The roller will rotate, drawing the metal through the blocks and forming a clean, uniform bend. Observe the bend as it completes; if the angle is slightly off, release the motor, readjust the blocks, and repeat the process. After each bend, inspect the joint for sharp corners or burrs and file or chamfer as needed. Repeat the cycle for multiple bends, maintaining consistent tension and angle settings. Always wear safety goggles and gloves, and keep the work area clear of loose clothing or accessories. By following these steps, you can reliably produce accurate, repeatable basic bends with the Hossfeld Universal Model No. 2 Bender.
This section emphasizes the importance of consistent tension and precise angle settings. Operators should routinely verify the alignment of the roller and blocks, calibrate the angle selector, and document any adjustments made during the process. Consistent practice leads to reliable, high‑quality results
Advanced Shaping Techniques (U-bends, irregular shapes)
To create U‑bends, start by selecting a block that matches the desired radius. Place the workpiece so that the bend axis aligns with the roller centerline. Secure the material with the 9B roller, then adjust the block angle to the target U‑bend angle. Use the pin set to maintain tension across the bend. Engage the motor slowly, allowing the roller to draw the metal through the block. Monitor the bend for uniformity; if the radius is too tight, release the motor, reposition the block, and retry. For irregular shapes, employ a custom‑cut block or a combination of blocks to guide the metal through multiple angles. The key is to maintain consistent tension and to adjust the roller speed to match the material’s flexibility. After each bend, inspect for burrs and use a deburring tool to smooth the edges. Document each configuration in a log to replicate complex shapes in future runs. Practice with scrap material to fine‑tune the process before working on final parts. This section emphasizes precision, safety, and repeatability in advanced shaping. Operators should calibrate the roller torque settings before each run, noting any deviations in bend depth that may indicate wear on the roller or block surfaces. By logging these parameters, maintenance teams can predict component lifespan and schedule timely replacements, thereby minimizing downtime and ensuring consistent product quality across production batches. Use a digital angle gauge to confirm the final bend angle meets the specified tolerancenow.
Maintenance and Troubleshooting
Regularly inspect the 9B roller for wear, clean the block surfaces, and lubricate pins. If bends become uneven, check roller alignment and block angle. Tighten all fasteners, replace worn parts, and recalibrate tension settings to restore precision. Ensure safety.All
Routine Maintenance Checklist
Follow this detailed routine to keep your Hossfeld Universal Model No. 2 Bender operating smoothly and safely. Perform the checks weekly, monthly, and annually as indicated. Weekly: Inspect the 9B roller for surface damage, clean the roller and block faces with a lint‑free cloth, verify pin alignment, and lubricate pins with a light machine oil. Monthly: Tighten all bolts, check the tension adjustment screw for proper torque, examine the block spacing for any shift, and test the safety interlock system. Quarterly: Replace worn roller bearings, re‑calibrate the bending angle gauge, inspect the hydraulic or mechanical drive for leaks, and verify the electrical connections for continuity. Annually: Conduct a full safety audit, replace all consumable parts, update firmware if applicable, and perform a comprehensive alignment test using a precision gauge block. Record all findings in the maintenance log, noting any deviations from the manufacturer’s specifications. Adhering to this checklist will extend the life of the bender, reduce downtime, and ensure consistent bending performance across all material types. Additionally, inspect the hydraulic cylinder for oil level and leaks, replace seals as needed, and clean the cylinder ports. Verify that the safety interlock switches are functioning by performing a lockout test. Check the alignment of the 9B roller with the 11B blocks using a dial indicator, ensuring the roller runs true. Maintain a log of all maintenance activities, including dates, parts replaced, and any observations. If the bender shows abnormal noise or vibration, stop operation immediately, inspect bearings, and consult the troubleshooting guide. Following this comprehensive checklist will help prevent costly repairs and ensure the longevity of the Hossfeld bender. For long‑term reliability, schedule a full hydraulic system flush every 12 months, replacing the hydraulic fluid with a high‑quality synthetic oil rated for the operating temperature range. Inspect the hydraulic hoses for cracks or wear, tightening fittings with the correct torque specifications. Verify that the power supply voltage matches the bender’s rated voltage, and check the circuit breakers for proper operation. Keep spare parts such as roller bearings, seals, and pins on hand to reduce downtime during unexpected failures. Document any deviations from normal operation and report them to the maintenance supervisor for corrective action. By adhering to these detailed procedures, operators can maintain optimal performance, extend equipment life, and ensure safety compliance across all bending tasks All tasks follow safety rules.
