Abstract
The invention discloses a cast aluminum die for casting a CBN (cubic boron nitride) grinding wheel with a grinding rod. The cast aluminum die for casting the CBN grinding wheel with the grinding rod comprises a die sleeve, a lower die cushion, a pressure bearing ring, a pressure ring, a core and the grinding rod, wherein the lower die cushion is arranged in an inner cavity of the die sleeve; the pressure bearing ring is arranged on an upper end surface of the lower die cushion; the pressure ring is arranged on the upper end surface of the pressure bearing ring; the core is arranged in an inner cavity of the pressure ring; the grinding rod is arranged in the lower die cushion; the pressure bearing ring comprises a left semi-circle portion and a right semi-circle portion; and the size of a gap between the left semi-circle portion and the right semi-circle portion is 0.03mm-0.05mm. By the mode, the cast aluminum die for casting the CBN grinding wheel with the grinding rod is high in strength, light in dead weight, convenient to construct and reliable in quality; the machined CBN grinding wheel is low in surface roughness and low in correction amount; the artificial polishing rate is greatly reduced; and the production efficiency of a product is improved.
Description
technical field [0001] The invention relates to an aluminum casting, in particular to a cast aluminum mold for casting a CBN grinding wheel with a grinding rod. Background technique [0002] Grinding wheel is the main grinding tool in mechanical processing plants. Grinding wheel is the most widely used abrasive tool. It rotates at high speed when used. It can be used for outer circle, inner circle, plane and various types of metal or non-metal workpiece Rough grinding, semi-finishing and fine grinding, as well as grooving and cutting, etc. [0003] The grinding wheel is generally made by pressing, and the pressing molds are various. Most of the pressing molds of the grinding wheel in the prior art adopt cast steel, which has a heavy quality and low operating efficiency. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a cast aluminum mold for CBN grinding wheel casting with grinding rod, which has high strength,...
