PURPOSE: A vacuum chamber device of a forming device is provided to maintain a vacuum state more stably, thereby improving a forming condition of a product and maximizing generality. CONSTITUTION: A vacuum chamber device(100) of a forming device comprises a fastening ring(10), a first chamber(20), a second chamber fixing ring(40), and a second chamber(30). The fastening ring includes a packing groove receiving a packing which is closely adhered to the outer periphery of a fixed ram(150). The first chamber includes a ram hole, a fastening groove where projections of the fastening ring are joined, a scrap groove receiving foreign materials or scraping oil, and a stopper preventing the separation of a second chamber. The second chamber fixing ring is closely adhered to the outer periphery of the first chamber, includes stopping projections hung on the stopper, and is joined to the second chamber with a fastening bolt. The second chamber is fastened to the second chamber fixing ring and includes a packing groove, thereby preventing the separation of the first chamber and preventing the inflow of air to the inside of the second chamber. |
