Description

Technical Field

[0001] The utility model relates to the technical field of abrasive tool manufacturing, in particular to a sintering device for producing superhard coated abrasive tools. Background Art

[0002] In the production process of superhard coated abrasives, sintering is a key step that directly affects the quality and performance of the final product. Although traditional sintering equipment can meet basic sintering needs, it has some obvious shortcomings in actual application, especially the problem that the sintering rack cannot be automatically moved in and out, which seriously affects production efficiency and operational safety.

Due to the compact space inside the furnace, operators need to perform delicate operations when placing and removing the abrasive tool, which not only increases the complexity of the operation, but also easily leads to damage or inaccurate positioning of the abrasive tool. The temperature inside the furnace is high, and operators need to be exposed to high temperature environment for a long time when placing and removing the abrasive tool, which may cause burns and other safety hazards. The high temperature environment not only poses a threat to the health of the operator, but may also affect their work efficiency and operating accuracy. Utility Model Content
