Product catalog summary

General Description

The document provides a detailed technical overview of the UCMSC series aerial cam units, specifically models UCMSC80 and UCMSC150, manufactured by Sankyo Oilless Industry, Inc. These cam units are engineered for piercing applications, emphasizing high durability, precision, and reliability in industrial settings.

Structure and Assembly/Disassembly Procedures

Disassembly: Remove hexagon socket head bolts and washers to detach safety and stopper plates, then slide the cam slider rearward out of the cam holder.

Assembly: Reassemble components in reverse order, ensuring sliding surfaces are clean and free of foreign matter. Clearance between guide bar, cam slider, and cam holder is controlled by matching stamped serial numbers on the holder and slider. All bolts must be reinstalled after disassembly to maintain structural integrity.

Options and Specifications

Option Codes:

K: Dedicated key attached but not assembled to the main unit.
SC: Mount surface extension adjustable from 0 to 60 mm in 1 mm increments.
WC: Mount width modification to 100 mm or 120 mm (WC100 or WC120).
N16: Dowel pin holes for cam holder and driver changed to h16H7 tolerance.

Performance Parameters

Working Force: Varies by model and travel angle, ranging approximately from 32.1 kN to 98.5 kN.
Spring Force: Initial load around 270.6 N (27.6 kgf), final load approximately 1623.6 N (165.7 kgf).
Travel Angles: Specified from 0° up to 60°, affecting force and spring characteristics.
Total Weight: Between 21.6 kg and 27 kg depending on configuration.

Spring Characteristics

The units utilize TL35-150 springs with a spring constant of 27.06 N/mm (2.76 kgf/mm). Key parameters include:

Free length: 150 mm
Length at initial load: 140 mm (10 mm deflection)
Length at final load: 90 mm
Stripping force measured at 5 mm punch retraction
Spring return force also measured at 5 mm punch return

Cam Diagrams and Dimensions

Detailed cam diagrams specify critical dimensions such as mount hole sizes, angles (e.g., 30°, 120°), and machining tolerances (e.g., ±0.02 mm). These ensure precise fitting and smooth operation of the cam units.

Ordering Instructions

When ordering units with the WC option, the piercing center position must be specified within the cam width. Catalog numbers and option codes must be clearly indicated to ensure correct configuration.

Critical Notes and Best Practices

Maintain cleanliness of sliding surfaces during assembly to prevent malfunction.
Ensure clearance by matching serial numbers on cam holder and slider.
Do not omit any bolts during reassembly to preserve structural integrity.
Use specified springs and adhere strictly to load and travel specifications for optimal performance and longevity.
If slider protrusion causes interference with the die, machine the die to provide adequate clearance.

Component Materials and Assembly

The document lists components for UCMSC80 and UCMSC150 units, detailing quantities, materials, and remarks. Materials include FCD450, FC250, SS400, S45C (1045), SCM435, bronze with graphite, urethane, SUJ2, and various bolts and springs. Components cover cam holders, sliders, drivers, slide plates, return mechanisms, guide pins, safety plates, keys, stoppers, coil springs, dowel pins, coned disc springs, and bolts, each identified by code and quantity to facilitate assembly and maintenance.
