A new utility patent thrust bearing gasket dotting device from NANFANG Precision Machinery

NanFang Precision (002553) obtained a new utility model patent authorization on February 7, 2025, named "A universal dotting device for thrust bearing outer flange gaskets", and its application number is CN202421242783.X.

This patent belongs to the field of bearing manufacturing technology and aims to provide a multifunctional dotting device for thrust bearing outer flange gaskets. The device includes an upper mold and a lower mold, wherein a carrier is provided in the center of the lower mold, and a plurality of relatively movable supporting blocks are mounted on the carrier, and a central through hole is formed between them. A radially slidable locking die seat is provided on the lower mold surrounding the carrier, on which a sliding locking die and a push block for pushing the locking die to move radially are installed. When the insertion rod in the center of the upper mold is inserted into this central through hole, each supporting block expands outward; and when the insertion rod is pulled out of the through hole, the supporting block automatically shrinks. This design not only supports the dotting and unloading operations of gaskets of different sizes, but also can adapt to gaskets of various specifications by adjusting the position of the pressure rod and the locking die base, thereby improving the applicability of the device and reducing costs.

It is worth noting that this year, NanFang Precision has obtained three new patent authorizations, although this number is 40% lower than the same period last year. In addition, according to the company's 2024 interim financial report, the company's R&D investment in the first half of the year reached 27.7265 million yuan, an increase of 1.56% year-on-year. This shows that despite the reduction in the number of patents, NanFang Precision still attaches importance to R&D investment and is committed to technological innovation.
