Stamping die and stamping device

Abstract

The invention provides a stamping die and a stamping device, and relates to the technical field of die manufacturing. The stamping die comprises an upper die, an edge pressing ring and a lower die which are sequentially stacked, wherein a first circulation channel capable of realizing heat transfer with the lower die is arranged on the lower die; and a flowing medium is contained inside the firstcirculation channel. During stamping, friction heat and deformation heat can be generated among the upper die, the lower die, the edge pressing ring and a sheet matal; the flowing medium in the firstcirculation channel can absorb the heat, and the heat is uniformly distributed in the first circulation channel; the first circulation channel can realize heat transfer with the lower die; meanwhile,the lower die can carry out heat exchange with the sheet matal through contact with the sheet matal; and according to the stamping die, the above arrangement can enable the temperature of the sheet matal to be kept during warm forming and stable production by virtue of the friction heat, contact heat and heat exchange among the upper die, the lower die, the edge pressing ring and the sheet matal,so that less energy sources such as electric power are consumed in the stamping process, the manufacturing cost is reduced, and friendly environment is facilitated.

Description

technical field [0001] The invention relates to the technical field of die manufacturing, in particular to a stamping die and a stamping device. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] In the prior art, in order to improve the formability of the steel plate and reduce cracking, increasing the temperature during steel forming has become one of the ways to improve the application ability of the steel plate. At present, the heating methods of steel plate include induction heating, electric heating wire heating and so on. After the steel plate is heated to an appropriate temperature, the steel plate is placed in a stamping die for processing. Howe...
