During the forging process of a disc forging, debris will be generated on the forging lower die and in the forging lower mold cavity. The debris in the cavity will affect the subsequent forging of forgings, so it is necessary to clean out the debris in the cavity. However, the debris in the cavity is difficult to clean and is easily not cleaned up. Utility Model Content

[0010] Preferably, a support column is installed on the forging platform, a rotating shaft is fixed on the support column, and one end of the cleaning rod is hinged on the rotating shaft. The cleaning rod is hinged on the forging platform through the support column and the rotating shaft, which is convenient for the installation of the cleaning rod.

[0011] Preferably, a pull rod is fixedly connected to the other end of the cleaning rod. The setting of the pull rod allows a worker to pull the pull rod to drive the cleaning rod to swing, which is convenient for cleaning debris.

[0012] Preferably, the other end of the cleaning rod extends outside the chip collecting housing, and two support rings are installed on the forging platform, which are located on both sides of the forging lower die, and the other end of the cleaning rod rests on the support ring. The setting of the support ring can support the movable end of the cleaning rod, improve the stability of the swing of the cleaning rod, and make the debris cleaning more clean.

[0013] Preferably, a plurality of support blocks are installed on the forging platform, and slots are provided on the tops of the support blocks, and the ends of the support rings are inserted into the slots. By inserting the ends of the support rings into the slots, the support rings are installed on the support blocks, and thus the support rings are installed on the forging platform, which facilitates the installation of the support rings.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0026] When forging a disc forging, the cleaning rod 9 swings to the outside of the forging lower die 3, and the top block 8 descends to clear the cavity 7 for forging. After forging is completed, the driving mechanism drives the top block 8 to rise to be flush with the top surface of the forging lower die 3, and the debris remaining in the cavity 7 is ejected. The cleaning rod 9 is manually swung to the other side of the forging lower die 3, and the debris on the forging lower die 3 and the top block 8 is cleaned into the chip collection chamber 10. After a period of use, the chip collection shell 4 is removed from the forging lower die 3, and the debris is dumped to facilitate the cleaning of the debris in the cavity 7 of the forging lower die 3, and the cleaning is cleaner.

[0027] As a preferred example of this embodiment, the cross section of the chip collecting chamber 10 is annular, the longitudinal section of the outer ring surface of the chip collecting chamber 10 is conical, and the longitudinal section width of the outer ring surface of the chip collecting chamber 10 is gradually expanded upward.
