Abstract

The invention provides a high speed stamping die with a low temperature lubricating structure and belongs to the technical field of dies. The invention solves the problems of bad cooling effect, bad lubricating effect and short service life of the current stamping die. The high speed stamping die with the low temperature lubricating structure comprises an upper die holder and a lower die holder, wherein a forming plate group composed of an upper die lining plate, a punch fixing plate, a discharge lining plate, a discharging plate, a lower template and a lower die lining plate is arranged between the upper die holder and the lower die holder, a forming assembly is arranged in the forming plate group, an oil gas path communicated with the forming assembly is arranged between the forming plate groups, and the inlet of the oil gas path is connected with a low temperature lubrication feeding device. The low temperature lubrication feeding device mixes and atomizes low temperature compressed air and micro-lubricating oil to form low temperature gas-liquid two-phase stream, and the low temperature gas-liquid two-phase stream is jetted to a stamping processing region through a gas channel so as to permeate the low temperature cold air to a stamping processing contact interface with oil particles atomized by the micro-lubricating oil to play a lubricating effect and effectively take away the heat generated during the stamping process.

Description

technical field

[0001] The invention belongs to the technical field of moulds, and relates to a high-speed stamping die, in particular to a high-speed stamping die with a low-temperature lubricating structure. Background technique

[0002] Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of the processed parts are directly related to the design and manufacture of stamping dies. High-speed precision progressive stamping technology is an advanced manufacturing technology with high efficiency and high precision, which represents the development level and direction of precision stamping technology. However, the deformation speed is too fast during high-speed stamping, which causes the plastic properties of the processed material to change, and the frictional heat generated by stamping will increase the temperature of the stamping die. Due to the high stamp...
