Induction hardening machines-Automotive-
- Semi-open coil tracks rotating part, minimizing warpage.
- Hardens pins as narrow as 10.5mm using thin coil and transformer designs.
- Power reduction method adjusts power as the part rotates to achieves even case depth.
- Coil-part positioning trend and total energy monitoring systems for hardening control.
- Compact design 1/3 of original volume and height under 2m for easier shipping, installation
- Coil moves eccentrically to track rotating cam.
- Achieves even casing and prevents nose cracking caused by overheating and post-process grinding.
- Automatic adjustment of coil position and parameters for each cam possible.
- Original concentrator ring prevents unnecessary heating of camshaft journals to ensure low warpage.
- Coil designed to match cam width to prevent drastic difference in temperature on the cam surface. Built without cores for long coil life.
- Semi-open coil built to the shape of the part generates axial current for even case depth.
- Original line coil one-shot hardening achieves even hardening without warpage.
- Energy consumption reduced 50% compared to scan hardening.
Constant Velocity Joint
- Converter with 3 frequency settings for hardening ball grooves, axle, and spline.
- Multi-turn coil achieves stable reheating.
- Air pockets in grooves minimized during quenching to prevent soft zones.
- Concentrator ring prevents overheating of edges and diagonal groove plunger.
- Semi-open line coil one-shot hardening treats two parts simultaneously.
- Shorter cycle time than traditional method while preventing overheating.
Gear Contour Hardening
- Precise temperate control minimizes deformation during heating and quenching.
Achieves ideal casing along the gear contour even for gears with small modules.
- IH hardening energy consumption 80% less than carburizing.
- Warpage minimized by pinpoint hardening.
- Automation possible for high productivity.
