Technical details and manufacturing context for Feed Frame

Definition

The Feed Frame is a critical structural component within Powder Feeding Systems that provides rigid support and precise positioning for various feeding mechanisms, hoppers, and metering devices. It ensures stable alignment and proper integration of feeding components within the overall system architecture. This frame is typically fabricated from carbon steel or stainless steel, with material grades such as 304 or 316L (the latter for corrosive environments) as referenced in ASTM A240. The frame's overall dimensions are customizable per machine layout, with a reference range of 800×600×400 mm (L×W×H), and its weight typically falls between 120 and 180 kg depending on material and thickness. Surface finish can be specified to Ra 0.8–1.6 μm (ISO 4287), with food-grade options available. Flatness and parallelism tolerances are held to ±0.05 mm and ±0.03 mm respectively, per ISO 2768-mK, ensuring sealing and feed accuracy. The operating temperature range is -20 to 80°C, with seals degrading above 80°C, and the operating pressure range is 1.0–1.6 MPa, noting that The frame's static load capacity is 500–1000 kg. IP ratings of IP54–IP65 (IEC 60529) are available, with IP65 for washdown environments. Mounting holes are sized for M10–M14 bolts, with diameters of 12–16 mm (ISO 273) and bolt hole spacing of 100–200 mm per drawing. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The Feed Frame is a part-level component, not a standalone machine, and its design must be integrated with the overall powder feeding system architecture.

Working Principle

The Feed Frame serves as a stationary structural foundation that maintains the geometric relationship between feeding components. It absorbs operational vibrations and mechanical stresses while ensuring consistent positioning accuracy for reliable powder transfer operations. By providing a rigid platform, it prevents misalignment of hoppers, metering devices, and other feeding mechanisms, which is critical for maintaining feed rate consistency and preventing material spillage or blockages. The frame's flatness and parallelism tolerances ensure that mating surfaces seal properly, and its load capacity supports the weight of mounted components. The frame does not actively participate in powder flow but rather provides the necessary stability and alignment for the system to function correctly.

Frequently Asked Questions

What is the primary function of a Feed Frame?

The Feed Frame provides rigid structural support and precise positioning for feeding mechanisms, hoppers, and metering devices within a powder feeding system. It maintains alignment and absorbs operational stresses to ensure reliable powder transfer.

What materials are commonly used for Feed Frames?

Feed Frames are typically made from carbon steel or stainless steel. Stainless steel grades 304 and 316L are referenced, with 316L recommended for corrosive environments. Material grade should be confirmed with the manufacturer for the specific application.

What are the key dimensional tolerances for a Feed Frame?

Flatness tolerance is ±0.05 mm and parallelism tolerance is ±0.03 mm, both per ISO 2768-mK. These tolerances are critical for sealing and feed accuracy. Actual values may vary based on the model and must be verified.

What operating conditions can a Feed Frame withstand?

The operating temperature range is -20 to 80°C, with seals degrading above 80°C. Operating pressure is 1.0–1.6 MPa. IP ratings up to IP65 are available for washdown. These are reference ranges; confirm with the manufacturer.
