More common grinding wheel products are ceramic grinding wheel, resin cutting grinding wheel, resin diamond grinding wheel, diamond saw blade, etc. Its processing and molding are mostly powder molding process. Shandong Zhongyou has designed and produced a grinding wheel powderforming hydraulic press, Three-beam four-column structure, can be used for the processing and production of various specifications of grinding wheel products. The equipment adopts a cartridge valve integrated system and uses high-pressure hydraulic oil to realize hydrostatic molding.
According to the material, specification, density and weight of grinding wheel products, Shandong Zhongyou can customize grinding wheels of 315 tons, 400 tons, 500 tons, 630 tons, 800 tons, 1000 tons, 1500 tons, 2000 tons, 2500 tons, 3000 tons, 3500 tons and other different tonnages.Powder forming hydraulic press, By changing the mold and pressure, a variety of different shapes and sizes of grinding wheel blanks can be produced.
The powder forming process of grinding wheel is mainly divided into two kinds, hot pressing method and cold pressing method. Hot pressing molding is made by mixing metal powder with diamond and adding grinding wheel powder to forming hydraulic press mold by hot pressing. This process requires a small hydraulic press, and the grinding wheel has good precision, high strength and long service life. Hot pressing molding is a method of mixing metal powder with diamond and adding cold pressing to the forming mold, using a grinding wheel powder forming hydraulic press to form, and then sintered, this process is relatively simple, long mold life, high efficiency of mass production cycle, low production cost.
Grinding wheel powder forming process
The abrasive and the binder are put into the mold of the grinding wheel powder forming hydraulic press. After the rotary table is evenly distributed, the piston of the main working cylinder pushes the movable beam down. When the pressure reaches a predetermined pressure (constant pressure pressing) or a predetermined stroke (constant range pressing), the pressure is held for a period of time, then the pressure is relieved and returned, and the ejector cylinder pushes out the finished product.
The hydraulic control of the grinding wheel powder forming hydraulic press designed and produced by Shandong Zhongyou adopts a cartridge valve integrated system, which reduces leakage points, has reliable operation and long service life, can realize two forming processes of constant pressure and constant process, has the function of pressure holding delay, can adjust the working pressure stroke within the specified range, adopts button centralized control, and can realize three operation modes of manual, semi-automatic and automatic. Equipped with appropriate auxiliary equipment and heating device, can press ceramic grinding wheel, resin cutting grinding wheel, resin diamond grinding wheel and diamond saw blade, etc. The use of plastic filling elastic mold, fixed weight feeding, fixed mold molding process. Mold rotation, scraper micro-lifting material, can be in the same mold forming different thickness grinding wheel.
