ApplicationsActivate Hardening on V-Belt
Application:
A manufacturer of automobile V-belts activating and curing a hardening compound on the rubber- based-compound belts.
Problem:
- New Process - A Japanese automobile manufacturer required the V-belt manufacturer to cure a hardening compound on the V-belts.
- Line Speed - The manufacturer required a line speed of 80 feet (24.4 meters) per minute to meet production output requirements.
- Automated System - To meet the required line speed, the manufacturer needed to develop an automated system to apply, activate and cure the hardening compound and cut the V-belts to the appropriate width.
- New Compound - The hardening compound was new and had never been applied, activated and cured in an automated production line.
- Scrap Rate Requirement - The manufacturer required a scrap rate that did not exceed 1% of production output.
Solution:
- Heat - Two Model 4554-A-05-12 High Density Pyropanels applied heat to activate the hardening compound and two Model 4554-A-05-06-IW High Density Pyropanels applied heat to cure the hardening compound on the V-belts.
- Power Control - A Model 664K Phase Angle SCR Power Controller controlled the power to each set of two High Density Pyropanels.
- Instant On/Off - The High Density Pyropanels responded instantly to production line starts and stops.
- Automated System - The High Density Pyropanels were incorporated into an automated system developed to apply, activate and cure the hardening compound and cut the V-belts to the appropriate width.
Benefits:
- Quality Curing - The infrared heat applied by the High Density Pyropanels activated nd cured the hardening compound according to the manufacturer’s requirements.
- Speed - By incorporating the High Density Pyropanels into the automated system, he manufacturer was able to achieve the required line speed of 80 feet (24.4 meters) per minute.
- Flexibility - The instant on/off capabilities of the High Density Pyropanels enabled the manufacturer to set the production line for different V-belt runs without a long delay in production.
- Limited Scrap - The number of V-belts that had to be scrapped was less than the 1% limit established by the manufacturer.
