The invention relates to a stamping tool with function of lubricating by punch-stored lubricant. The stamping tool comprises a punch rod (1). A punch is connected to the lower end of the punch rod (1) and comprises a punching part (3) and an extension part (2). The extension part (2) is arranged on the upper portion of the punch and connected with the punch rod (1). The punching part (3) is arranged at the lower end of the punch. A plurality of layers of oil storage cavities (4) are arranged between the punching part (3) and the extension part (2) and evenly surround outside the side of the punch. When the punch is at the initial state, the parts, corresponding to the oil storage cavities (4), of a machine tool (5) are provided with oiling grooves (6) which correspond to the layers of oil storage cavities (4) respectively. The stamping tool has the advantages that the punch is provided with the multiple layers of oil storage cavities, and every time before the punch extends out, lubricant is charged through the oiling grooves and the lubricant is even and not wasted; accordingly, cost is reduced and environmental pollution is reduced.
Description
technical field [0001] The invention belongs to the technical field of cup-shaped stamping equipment, and in particular relates to a stamping die for punch oil storage lubrication. 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 stamping die with oil storage lubrication...
