Description

Technical Field

[0001] This utility model belongs to the field of metal parts processing technology, specifically a vacuum tempering furnace device for metal parts processing. Background Technology

[0002] Tempering is a crucial process in modern metal processing. It aims to reduce the brittleness of workpieces. The process involves holding the quenched workpiece at a suitable temperature above room temperature but below 710°C for an extended period before cooling. A vacuum tempering furnace is typically used for this process. A vacuum tempering furnace generally consists of a horizontally placed furnace base and a furnace box located on the furnace base. The workpiece is placed inside the furnace box, the air inside is extracted, and the furnace box is then heated to temper the workpiece.

[0003] Currently, after quenching, automotive parts need to undergo tempering to improve their surface strength. In most existing tempering devices, the automotive parts are simply stacked on a rack and then pushed into the tempering device for tempering. Since the automotive parts are stacked as a whole, their surfaces are heated unevenly, which can easily affect the tempering effect. Utility Model Content
