[ Compressor valve for car air conditioner - Blanking Die ]
Compressor valve for car air conditioner This part is a component of cars air conditioner compressors.
They are made of a very hard spring steel and function as valves to regulate the vaporization and liquefaction of the refrigerant.
The products in the photo are a discharge reed valve and a suction valve.
[ Specifications ]
- Workpiece material: Sandvik 20C
- Tensile strength: 2060 Mpa (equivalent HRC55)
- Product size: approx. φ105mm
- Thickness: 0.38t
- Press: AIDA 400t
[ Features ]
- Component of car compressors. They act as a valve, and are made of a very hard spring steel (HV580).
- The hardness of the material to be machined is almost similar to that of the die material, which therefore is required to be very rigid.
- In order to prevent chipping of the cutting material, a small radius is machined on their cutting edge to ensure stable mass production.
- The φ3 standard holes needs to have a long shear surface length. A punch/die clearance of no more than 10μm is required and maintained in order to fulfill this requirement.
- The position of the φ3 holes is adjusted if the pitch between them changes after stamping.
- As a valve, it is important to prevent any risk of cracks. We stamp these parts in one piece, without dividing its blanking in separated operations (no matched areas).
