The rapid rise of new energy vehicles has led to the development of lithium batteries. The establishment of lithium battery anode materials in China generally requires graphite crucible products, which makes the demand for graphite crucible production equipment begin to increase. Shandong Zhongyou designed and produced a graphite crucibleforming hydraulic press, Three-beam four-column structure, using powder molding process, with the mold can process graphite crucibles of various specifications and diameters.
According to the material, specification, diameter and density of graphite crucible, Shandong Zhongyou can customize 1000 tons, 1500 tons, 2000 tons, 2500 tons, 3000 tons and other different tonnages of graphite crucible forming hydraulic press. Compared with the traditional production process, it has the advantages of simple process, short production cycle, high yield and efficiency, low labor intensity, less molding moisture, low crucible shrinkage and porosity, and high product density.
200-400mm diameter graphite crucible generally use 315 tons, 400 tons, 630 ton hydraulic pressProcessing, diameter 500-800mm is 1250 tons, 1500 tons, 2000 tons of hydraulic press processing, diameter greater than 800mm using 2000 tons, 3000 tons of hydraulic press processing.
Among so many graphite crucible forming hydraulic presses of different tonnage, the high purchase rate is 2000 tons, which can press ordinary graphite crucibles with a diameter of about 500-600mm, and large-diameter graphite crucibles with a diameter of less than 1000mm. It can not only press cylindrical crucibles such as graphite crucibles, clay crucibles, silicon carbide crucibles, but also press ten-hole plum blossom crucibles for one-time molding.
Graphite crucible molding is to place the graphite crucible mixture into the mold and start the graphite crucible molding hydraulic press. When the slider decelerates for a certain distance and approaches the workpiece, the pressure in the upper cavity of the master cylinder will be determined by the pressing load. The pressure in the upper cavity of the master cylinder will continuously increase, and the output flow of the variable pump will automatically decrease accordingly. When the pressure in the upper chamber of the master cylinder reaches the set pressure of the pilot relief valve, the output flow of the pump is all over the valve, and the slider will stop moving at this time. The main cylinder can complete the basic working cycle of rapid downward movement, deceleration pressing, pressure holding delay, pressure relief return and stop (any position), and complete the molding production of graphite crucible.
