The present invention relates to a gravity sintering apparatus for forming melt copper lining of a cylinder block for a piston pump and a piston motor, more specifically, wherein impurities having bubbles and pure melt copper are separated to form an excellent lining portion. According to the present invention, an upper cover plate (112) and a lower cover plate (113) are installed to be spaced from each other in an upper and a lower portion in front of a casing (110), and an opening and closing door (114) is installed on a rear surface of the upper cover plate (112). A rotary shaft (122) is horizontally installed in an upper portion of a support frame (120), and a central portion of a rotating drum (30) is connected to and installed in a front end portion of the rotary shaft (122). A lower support (33) and a cylinder (34) are installed in an internal wall surface of a cylindrical wall (37), and a cover (36) is installed in a lower end portion of a cylinder rod (35) of the cylinder (34). |
