Optimized hangers for new challenges

Requirements for hangers

Hangers need to manage wheels with significant different shapes and dimensions from 14” to 24”.

In special cases, additional adapters are required to manage 14” wheels or with unbalanced weight distribution in the wheel.

Ultimate quality for hangers

Requirement

In order to be able to manage wheels from 14” to 24” with high design differences, hanger manufacturing has to undergo a final quality check

to ensure the highest precision.

Spindle cleaning from the top to the bottom

SCM seriesRequirement

Spindles have to be cleaned after powder paint application

to prevent contamination of certain areas of the wheel

surface

Spindle cleaning machine SCM 200 for complete

automatic spindle cleaning

Spindle

Shaft

Trolley


Spindle cleaning machine SCM 200

Process cycle (running mode)

1. Each 1/6 rotation of the spindle is cleaned by the

ramp

2. Accurate vacuuming prevents powder from

escaping

3. Conveyor cleaning provided

4. Adjustable time for «upper nozzles ramp» from HMI

5. Adjustable time for «bottom nozzles ramp» from

HMI

6. Adjustable frequency of the «bottom nozzles ramp»

from HMI


Spindle cleaning machine 200

Your benefits

1. Compact design

2. Pneumatic cleaning

3. Adaptability to the conveyor

4. Rotation of the spindles: sequential cleaning cycles

5. Static stabilizers for the spindles during cleaning

6. Easy maintenance

7. Easy handling

8. Process customizations

9. No contamination of the surrounding working area

with powder paint

10. Ex-certified

Center bore cleaning

Requirement

After powder paint application and before entering the oven, paint deposits have to be removed from the

centering bore up to a fixed height depending on the type of wheel.


Mounting face cleaning

Requirement

After powder paint application, paint deposits on the mounting face has to be removed before entering the

oven.


Large design variety

24’’ Wheel14’’ Wheel

Requirements

Wheels nominal

diameter 14’’÷24’’

Mounting face

up to 200 mm


height >30 mm

Cycle time < 1,5 s for

high capacity lines


Center bore and mounting face cleaning

Technical demands for development

1. Better cleaning results on mounting face and center bore

Mixed Cleaning: Compressed air for center bore, brushes for mounting face

2. Variable height of cleaning area

Central nozzle can be manually adjusted in a vertical direction

3. Keep the cleaning device uncontaminated

Vacuuming the powder paint from the center bore

4. Support of the wheel from an area without any chance of contamination

“Life ring” is the area on which the wheels touch the heads

5. Prevent mounting face being re-contaminated from powder from the center bore

“Life ring” also realizes sealing for vacuuming the powder paint

6. Flexible vertical positioning

“Life ring” pushes the head and implements the wheel position to the defined height of center bore cleaning
