Product Characteristics
The thick plate straightener is suitable for leveling metal coil materials with thicknesses ranging from 1.0 to 6.0mm. It adopts a worm gear structure to replace the screw rod pressure material commonly used in traditional straighteners. The material is moved through the straightener by a cylinder. The height adjustment of the leveling upper roller is made by rotating the handwheel, which is simple and convenient. With each full rotation of the handwheel, the leveling upper roller moves down by only 1mm, ensuring ease of operation, high speed, and high precision.
The leveling adjustment mechanism integrates a compact worm gear and worm wheel system, ensuring smooth torque transmission with reverse self-locking capability. Equipped with single-direction thrust ball bearings, it withstands axial forces, maintains stable guidance, and resists high-impact loads.
Operates effectively as a standalone unit or seamlessly integrates with MT-type and CR-type material uncoilers for enhanced workflow efficiency.
Equipped with synchronized worm gear adjustment technology, the upper rollers achieve 1mm vertical displacement per full handle rotation, enabling accurate and repeatable leveling control.
This design delivers micron-level adjustment precision while maintaining simple, operator-friendly manual control—ideal for frequent material thickness changes.
A heavy-duty structural design combined with a high-power drive system enables stable high-speed material feeding without compromising leveling accuracy.
Built for continuous industrial operation, the HCL straightener ensures long-term durability, high productivity, and reduced maintenance costs, even under demanding production conditions.
Machine specifications can be customized according to material thickness, width, and strength.
The synchronized movement of upper and lower rollers, together with precision-ground, hardened steel leveling rollers, ensures uniform pressure distribution.
This design effectively prevents surface scratches, dents, or indentation marks, making the machine suitable for processing materials with strict surface quality requirements.
The machine incorporates Japanese-brand electrical contactors and industrial-grade electronic components, ensuring stable control performance and minimized downtime.
All critical components are selected for long service life, supporting over 100,000 operating hours in continuous production environments.
This coil processing equipment setup consists of an automatic uncoiler, HCL Type thick plate straightener, and an NC servo feeder, forming a complete coil feeding line.

FAQ
Q: How do I determine the right feeder size for my production line?
A: The feeder size depends on the material width, thickness, and feeding step distance required by your stamping press. Choosing the correct specifications ensures smooth operation and prevents feeding errors or misalignment.
Q: What factors should I consider when choosing a servo feeder machine?
A: When selecting a servo feeder, key factors include feeding accuracy (±0.05mm or better), maximum feeding speed (e.g., 20m/min), material compatibility (stainless steel, aluminum, etc.), load capacity, and control system (PLC or touchscreen). Ensure the machine matches your stamping process requirements.
Q: How do I choose the right decoiler, straightener and feeder?
A: Select based on material type, width, thickness, coil weight, and required speed. Match decoiler capacity to coil size, choose a straightener for material strength, and a feeder that meets feed length and precision. Ensure compatibility with your press and automation level.
Q: Coil feeder vs servo feeder: what’s the difference?
A: A coil feeder is a broader system for continuous coil feeding, often integrated with decoiler and straightener. A servo feeder uses servo motors for precise, programmable feeding, ideal for short pitches and high accuracy applications.
Q: How to choose decoiler capacity?
A: Select a decoiler rated 10–20% above your maximum coil weight. Confirm inner diameter (I.D.) compatibility and outer diameter limits. Adjustable mandrels are recommended if you run multiple coil sizes.
Q: What feed precision can I expect?
A: Servo feeders typically achieve ±0.01–0.05 mm, with high-end models reaching ±0.005 mm. Mechanical feeders usually provide ±0.02–0.1 mm. Actual accuracy depends on material properties and straightening quality.
Q: How does material affect machine selection?
A: High-strength materials need stronger straightening and drive systems. Thin materials require low-pressure handling. Soft materials like aluminum need anti-scratch solutions.
Q: What affects feeding accuracy most?
A: Key factors include feeder precision, servo tuning, straightener setup, material quality, and press stability. Poor setup or worn dies can reduce accuracy.
Q: What spare parts should be prepared?
A: Common spares include bearings, belts, sensors, seals, guide blocks, and lubrication parts. Keeping key components reduces downtime and improves maintenance efficiency.
Q: Can feeders be retrofitted to existing presses?
A: Yes, most systems support retrofitting. Check press dimensions, feed height, control compatibility, and safety requirements before installation.
Q: How long does it take to receive the feeder machine after placing an order?
A: Lead time for delivery typically ranges from 4 to 8 weeks depending on customization, production schedules, and shipping location. Once your order is confirmed, we will provide a more precise delivery estimate.
Q: What are your payment terms?
A: We accepts T/T payment, 30% deposit and 70% balance before shipping
Q: How often should I perform maintenance on my servo feeder machine?
A: Routine maintenance should be conducted weekly for basic cleaning and lubrication, while a more thorough inspection should be done monthly to check for wear on rollers, belts, and electrical components. A full servicing is recommended every 6-12 months depending on usage intensity.
Q: What are the most common issues with feeder machines, and how can I troubleshoot them?
A: Common issues include misalignment, inconsistent feeding accuracy, or motor failure. Check for loose bolts, dirt buildup, or software calibration errors. If problems persist, refer to the user manual or contact technical support.
Q: Do you provide on-site repair services if my machine breaks down?
A: Yes, we offer on-site repair services for major issues, along with remote troubleshooting support for minor problems. For urgent cases, we can dispatch a technician within 24-48 hours, depending on your location.
Q: What is the maintenance cycle?
A: Daily cleaning and inspection; weekly check belts, air lines; monthly inspect bearings and guides; yearly replace worn parts. Adjust frequency based on operating hours and workload.
Q: What's the package of your coil feeding machines?
A: For the coil feeding equipment that go LCL shipping, We will use plastic films wrap on the equiment, and then fix it into a wooden box.
For the large coil lines that go FCL shipment, We will fix each part with ropes on the shipping container and then wrapped them with plastic films.
Q: What is the typical lead time?
A: Standard machines usually take 4–8 weeks. Customized systems or full production lines may require 10–20+ weeks depending on complexity and production schedule.
