Formula for electric power density:

Electric power density (W/cm2) = Electrical power (W) ÷ [Heater O.D. (cm) x π(3.14) x heating section length (cm)]

Heating section length (cm) = [Heater length (mm) - 7 (mm)] / 10

IDEA NOTE Cost reduction by limiting components

Since the heater is supplemental to the cutting process, precision temperature control sensors are omitted to reduce cost.

    CAD Data Limitations

    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. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or 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

  • Combining a cartridge heater with a blade to cut specified lengths of resin belt.

Target workpiece

  • Thin resin belt.
  • Workpiece size: Width 200, Thickness 1mm

Design Specifications

Operating Conditions or Design Requirements

  • External dims.: W305 x D400 x H262 mm
  • Stroke: 40mm

Selection Criteria for Main Components

  • Cartridge heater
    • The electrical wire harness is perpendicular to the heater.

Design Evaluation

Verification of main components

Verify the electric power density of the heater based on the required amount of heat.

  • Conditional value: Mass of heated object M = 3 kg
    Specific heat Hc = 0.110 for the object to be heated [kcal / kg ℃]
    Temperature rise Ta = 60℃ (Normally 20℃ is raised to 80℃)
    Heating time Tm = 0.25 h
    From efficiency η = 0.3
  • Required amount of heat for the heater Q[kW] = (M × Hc × Ta) / (860 × Tm × η)
    = (3 × 0.110 × 60) / (860 × 0.25 × 0.3)
    = 0.307kW = 307W
  • Power density of heat generating section [W / cm²] = W / (3.14 × (D / 10) × (L / 10 - 1.5))
    =310 / (3.14 × 0.8 × 30 - 1.5）
    =4.3 W/cm²
    →(2 ≦ 4.3 [W / cm²] ≦ 15), this can be produced.

Other Design Consideration

  • The blade is placed diagonally to improve the cutting performance.
