This series of hydraulic machines designed specifically for friction plate industry for automotive brake pads pre-press molding, automatic control, with quick cylinders, cylinder push button station with back and forth, easy operation, high efficiency, high performance, and operating personnel safety features Four-and host-frame two structures, machine using finite element analysis, structural optimization is reasonable, good strength, force small deformation, so that the machine is more sophisticated, higher safety factor. Column hydraulic machine hydraulic control part adopts the advanced cartridge valve integrated system, long life, simple structure, compact, sensitive, reliable, easy maintenance, high level of generalization. Electrical control system adopts PLC industrial computer controller, each process action can be set on the display and display the relevant time, pressure, exhaust frequency, etc.; and a separate electrical and hydraulic power, enabling adjustment, manual and semi-automatic operation way. Hydraulic machine is mainly applied to the friction material cold or hot pressing, such as automobile clutch, brake pads and other similar products. In turn connected to the mold frame template die and the lower die, the fixed die, the template processing device composed of flour, said upper and lower mold were fixed on the upper and lower punch means, the punch means in said inner sleeve core Stick device mandrel device and add flour cylinder device is connected; connected to both sides of the die feeding boxes and die under the template via connecting rod and its innovation in that: the initial powder and powder cylinder by cylinder device Add flour and secondary tanks in series. These structural advantages are: molding pressure, molding methods, two powder height can be set automatically, once set, the machine automatically complete the action, you can achieve unattended operation, the product powder batch consistency, and no defective phenomenon.
