UCNBK65

Product catalog summary

General Description and Overview

The UCNBK series aerial cam units are precision-engineered mechanical assemblies designed primarily for piercing and flange applications. They feature a high-rigidity box structure with a V-shaped guide to ensure slider stability. Available mounting widths include 65mm, 100mm, and 200mm, with multiple model variants identified by catalog numbers such as UCNBK65-30 through UCNBK65-70.

1. Components and Materials

Main Components: Cam slider, cam driver, cam holder, upper plates, positive return followers, stopper plate, spring guide pin, coil spring, various plates (including cam bottom guide and slide plates), and stoppers.
Materials: Sliding and structural parts primarily use FC250 cast iron with graphite for low friction; S45C (1045 steel) for followers, plates, and stopper plates; SCM435 steel for spring guide pins; bronze with graphite for guide plates; and urethane for stoppers.
Bolts: Assembly bolts are referenced (e.g., SOUK65-30 / 35) but not detailed in the document.

2. Mechanical Specifications and Dimensions

Travel Range: Varies by model from approximately 33.5 mm to 65 mm.
Working Force: Initial working forces range from 19.6 kN (2.0 tonf) up to 54.5 kN (5.5 tonf), with allowable forces specified for 300,000 strokes to ensure durability.
Spring Details: Coil springs used include models TL30-125 and TL30-100, with spring constants around 23.76 N/mm (2.42 kgf/mm) or 29.69 N/mm (3.03 kgf/mm) depending on the variant.
Spring Durability: Guidelines specify durability from 300,000 to 1,000,000 strokes depending on spring type and model.
Deflection and Lengths: Initial spring deflections range from 10 to 18 mm; free spring lengths are typically 100 or 125 mm; lengths at initial and final loads are provided for precise setup.
Dimensional Details: Includes hole sizes (e.g., 2-h10H7, 4-h13-h20), dowel pin hole specifications, plate thicknesses, and mounting hole details with references to detailed pages for tapped holes and dowel pins.

3. Performance Data

Working Force and Load: Each model specifies initial and final loads in Newtons and kilogram-force, with corresponding spring forces and return forces.
Spring Force at Punch Retraction: Defined as 'z', representing the spring force when the punch retracts 5 mm; 'e' denotes the spring return amount at this retraction.
Working Life: Standard working force ratings are for one million strokes; allowable working forces are rated for 300,000 strokes to ensure reliability.

4. Assembly and Disassembly Procedures

Disassembly: Loosen hexagon socket head bolts to remove plates and dowel pins, then pull the cam slider rearward from the cam holder.
Assembly: Reverse disassembly steps, ensuring sliding areas are clean and free of foreign matter. Clearance between cam slider and holder is controlled by matching stamped serial numbers. All provided bolts must be reassembled to maintain structural integrity.
Options: A key for the holder (option code 'K') can be attached but is not pre-assembled. Detailed specifications for tapped holes and dowel pin holes are referenced for proper installation.
Space Requirements: Specific space is required for removal of keys and components, with further details referenced in the document.

5. Component Tables and Materials

Detailed tables list each component’s quantity, material, and remarks to aid manufacturing and maintenance.
Key materials include FC250 with graphite for sliding parts, S45C for structural components, SCM435 for guide pins, bronze with graphite for guide plates, and urethane for stoppers.

6. Recommendations and Best Practices

Maintain cleanliness of sliding areas during assembly to ensure performance and longevity.
Match serial numbers on cam slider and holder to maintain proper clearance and function.
Use all provided bolts during reassembly to ensure structural integrity.
Select springs according to required travel and working force to maintain durability.
Follow specified tolerances and hole finishes for proper assembly and function.
Refer to detailed pages for hole specifications and key details to ensure correct installation.
Monitor spring deflection and load parameters during maintenance to prevent premature failure.

Summary

The UCNBK aerial cam units are robust, modular mechanical components designed for piercing and flange applications, offering multiple size options and detailed assembly instructions. Comprehensive performance data and strict material and dimensional specifications ensure reliable operation and longevity. Adherence to assembly procedures, maintenance guidelines, and spring durability recommendations is critical for optimal performance.
