The invention discloses a novel metal composite molded automatic hydraulic machine. A drawing route cylinder barrel is arranged at the center of the upper portion of a piston for a main cylinder. A drawing route plunger is installed in the drawing route cylinder barrel. A drawing oil hole passage communicated with the drawing route cylinder barrel is formed in the drawing route plunger. An oil-adding oil way is arranged on an oil way board, the oil-adding oil way is connected with a main forcing oil way and a main forcing cavity, and a drawing oil way connected with a drawing oil hole passage is arranged on the oil way board. The outer end opening of the oil-adding oil way is connected with an external oil-adding oil tank. According to the novel metal composite molded automatic hydraulic machine, the drawing route cylinder barrel is arranged at the center of the upper portion of the piston for the main cylinder, and the drawing route plunger is matched, so that the composite molding is realized; the external oil-adding oil tank is arranged, so that a built-in oil-adding oil tank of an upper beam is leaved out, the manufacturing cost is lowered, and the service life is prolonged; at the same time, a forcing oil cylinder is further connected, so that the application pressure range of the metal composite molded automatic hydraulic machine is larger, and more metal products can be manufactured.
Description
technical field [0001] The invention relates to an automatic hydraulic press, in particular to a compound forming hydraulic press for forming metal products. Background technique [0002] Existing metal composite forming automatic hydraulic presses have a variety of structures, among which a metal composite forming automatic hydraulic press is reformed from a ceramic brick press, which is used in the cookware industry to produce aluminum pots with thin walls and thick bottoms. The fuselage of this metal composite forming automatic hydraulic press adopts the winding frame of the ceramic brick press, and the upper beam 1 is provided with a built-in replenishment oil tank 7`, which is connected to the main body through a large-diameter non-standard liquid filling valve 72`. The main pressurized chamber 33 of the oil cylinder 3 is connected. In order to meet the technical requirements of cold stamping of aluminum products, four plunger cylinders 9 are arranged around the origin...
