    Cautions on the CAD data

    1. Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
      You will need to edit the Data so that it meets your specific design conditions.
    2. The CAD data unit assembly consists of sub-assemblies.
      Each sub-assembly unit can be used as it is or can be edited.

      3. * The part in the frame is a sub-assembly unit.

    3. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    4. The Data including the third-part components are made by the Company.

Application Overview

Purpose

  • A cut-to-length process that incorporates an open / close guidance system made using a double acting cylinder and cam mechanism.
  • Operation order: (1) The cylinder pushes out (2) Cam driven shutter opens (3) Workpiece is cut (4) The cylinder returns (5) Cam driven shutter closes

Target workpiece

  • Plastic case
    Dimensions: W125 x D25 x H20
    Workpiece weight: 0.08kg

Design Specifications

Operating Conditions or Design Requirements

  • Stroke 50mm
  • External dims.: W120 x D217 x H374

Required Performance

  • Spring compression load: 20N
    Spring constant: 1.0N/mm

Selection Criteria for Main Components

  • Spring
    • Select a set of springs with load ratings that are higher than that of the weights being supported above them.
  • Cylinder
    • Select a double acting cylinder with sufficient force rating to push against the springs.

Design Evaluation

Verification of main components

  • Ensure the selected cylinder is able to generate a force adequate to push down on the springs.
  • Spring
    • Load = Spring constant x Deflection amount x Quantity used = 1.0N/mm x 10mm x 2pcs. = 20N > 9.6N (Load applied upon the springs) .
  • Cylinder
    • Select a cylinder that can generate 40N ( = 20 x 2: x 2 Safety margin) vertically.
    • Select a cylinder with 90N force from the catalog, and obtain the tube inner diameter dmm.
    • Tube inner diameter dmm = √ (Force x 4 / (Load factor x Pressure used x π)) = √ (90N x 4 / (0.5 x 0.4MPa x π)) = 23.9mm.
    • Therefore a cylinder of Ø25mm is selected.

Other Design Consideration

  • A pusher mechanism for the next section of the workpiece.
  • Timing between shutter opening and cutting of the workpiece.
