Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chain processing, in particular to a die forging detachable chain for a scraper reclaimer. BACKGROUND

[0002] Die forging chain, also known as die forging detachable chain, is mainly used for suspended conveyors and is the main transmission component in chain conveyors. It is used in almost all industrial fields, such as automobile factories, motorcycle factories, home appliance factories, furniture factories, and assembly line production lines.

[0003] Chinese patent (publication number: CN213206453U, publication date: 2021.05.14) discloses a die forging detachable chain for a scraper reclaimer. It includes a die forging chain and a rotating device installed at the rear end of the die forging chain. The die forging chain includes two die forging chains, a connecting pipe at the front end of the die forging chain, and a connecting groove at the rear end of the connecting pipe. The front end of the connecting pipe is provided with a fixed head, and the fixed head is located inside the connecting groove. Fixed blocks are fixed on both sides of the fixed head. Rotating holes are formed at the rear end of both sides of the connecting groove. The rotating device is fixed with a fixed disc through a rotating column at the front end. The rotating column is rotatably connected with the rotating hole. A fixed groove is formed in the inside of the fixed disc. The fixed blocks are inserted and matched with the fixed groove. In the utility model, the insertion and matching between the fixed blocks and the fixed grooves facilitate the disassembly of the die forging chains. The stable blocks facilitate further fixation of the die forging chains. The nuts connect the bolt heads and the connecting heads, which facilitates the stable connection of the die forging chains. However, since the chain connects the stable blocks and the fixed disc through bolts, the chain cannot lubricate the bolts, which makes it difficult to remove the bolts after long-term use due to lack of lubrication.
