Technical Field

[0001] The utility model relates to the technical field of forging machines, in particular to a cleaning device for a file making machine. Background Art

[0002] The crosspiece of anchor chain is an important part of anchor chain products, and its appearance quality directly affects the quality of anchor chain products; the crosspiece making machine is a forging machine used to produce crosspieces of anchor chain. It is a device for cold processing of metal and machinery. Driven by the hydraulic system, the fixed die seat, the upper extrusion die and the left and right extrusion dies forge the high-temperature steel billet from the top, bottom, left and right directions to generate crosspieces.

[0003] During the forging process of high-temperature steel billets, the surface of the forging will fall off. Under high temperature and high pressure conditions, the die metal and the detached impurities may react to form carbides deposited on the die surface, which will have a great impact on the quality of the subsequent forged crosspieces over time.

[0004] The existing forging die of the file making machine is provided with nozzles on both sides. The cooling liquid sprayed by the nozzles can wash the surface, but the cooling liquid is difficult to remove the impurities that are closely attached. Utility Model Content

[0009] As an optimization, a scraper is fixedly provided at one end of the connecting rod close to the fixed mold seat, and a scraping groove is opened on the scraper that is adapted to the contact surface of the fixed mold seat and the upper extrusion mold, as well as the contact surface and stamping surface of the left and right extrusion molds; the contact surface and stamping surface of the mold are cleaned by the scraper.
