The invention relates to a die with an oil storage punch. The die comprises a punch pole (1). The lower end of the punch pole (1) is connected with the punch. The punch comprises a punching part (3), a lubricating part and an expanding part (2), wherein the expanding part (2) is located on the upper portion of the punch and connected with the punch pole (1), the punching part (3) is located at the lower end of the punch, the lubricating part is arranged between the punching part (3) and the expanding part (2), and an oil storage tank (4) which surrounds the outer edge of the side face of the punch is arranged in the lubricating part. When the punch is in an initial state, a refueling pipe (5) is arranged at the position, corresponding to the oil storage tank (4), of a machine tool and connected with lubricating oil through a pipeline (6). The die has the advantages that the oil storage tank is formed in the punch, lubricating oil is refilled through the refueling pipe every time before the punch stretches out, lubricating oil is even and not wasted, and therefore cost and environmental pollution are reduced.
Description
technical field [0001] The invention belongs to the technical field of cup stamping equipment, in particular to a mold with an oil storage punch. Background technique [0002] Metal cup stamping is widely used, such as daily necessities such as stainless steel cups and washbasins, and various covers and shells in industrial applications. And in the stamping process, since the punch and the blank are all made of metal materials, adding lubricating oil is a necessary process. In the prior art, it is usually applied in advance on the sheet-shaped blank, or sprayed at the stamping position. In the use and application, there will be situations such as the uneven flow of lubricating oil due to the inclination of the billet, or the environmental pollution caused by excessive spraying and waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mold with an oil storage punch. A storage tank is arranged on the punch, and...
