This utility model discloses a high-precision anti-sticking die punch, relating to the field of punch press technology. It includes a punch press body, an externally fixed mounting base, an internally fixed cylinder, an output block fixedly connected to the cylinder, a die holder fixedly connected to the upper side of the punch press body, a die groove on the upper side of the die holder, a cavity inside the die groove, a slidingly connected top block to the outside of the cavity, a limit plate fixedly connected to the bottom of the top block, a fixed rod fixedly connected to the inside of the cavity, a rebound mechanism mounted on one side of the mounting block, a linkage mechanism mounted between the mounting block and the limit plate, and an auxiliary demolding mechanism mounted inside the cavity. This punch press achieves automatic ejection of the formed part through the energy storage and release of an elastic element, ensuring rapid demolding. An additional manual operation component allows for manual intervention to provide auxiliary ejection force when automatic ejection is obstructed, effectively preventing die sticking and improving operational certainty and convenience.

This invention discloses a process for stabilizing the cooling water supply temperature of a blast furnace, relating to the field of blast furnace ironmaking equipment cooling technology. The process includes the following steps: acquiring first and second real-time operating parameters and real-time status parameters of a shared spray water system; determining the smelting load difference between the first and second blast furnaces based on the first, second, and real-time operating parameters and the real-time status parameters; generating a linkage control command when the smelting load difference meets a preset linkage trigger condition; and allocating the number of air coolers in the first and second blast furnaces to operation by adjusting the linkage control valves between the air cooler branch pipes of the first and second blast furnaces according to the linkage control command. This invention relies on the existing shared spray water system, eliminating the need for adding a large number of new spray water devices, and achieving on-demand allocation of cooling capacity only through linkage and minor equipment modifications.
