Problems solved by technology

[0003] However, when the powder metallurgy hydraulic molding machine is in use, the powder will be in contact with the air during the extrusion molding process of the oxidized powder, causing the powder to oxidize. At the same time, the workpiece that needs to be moved into the sintering furnace will be oxidized The workpiece will cause insufficient strength of the workpiece, so that the quality of the product cannot meet the requirements

Abstract

The invention provides an anti-oxidation powder metallurgy hydraulic forming machine. The anti-oxidation powder metallurgy hydraulic forming machine is characterized in that a rotating cover is connected to the front end face of a sintering furnace through a hinge, a supporting frame is fixedly connected to the upper end face of the sintering furnace in a welded mode, a hydraulic cylinder is connected to the upper end face of the supporting frame, a telescopic rod is connected to the position, in the supporting frame, of the lower end face of the hydraulic cylinder, an upper shaping device isconnected to the lower end face of the telescopic rod, and a lifting rod is connected to the lower end face of the upper shaping device in a penetrating mode. According to the anti-oxidation powder metallurgy hydraulic forming machine, a lower shaping device composed of a power motor, a shaping plate, a winding device, a sliding device, a lower shaping mold, a cutter groove and a rotating wheel isarranged, the rotating wheel can be well driven by using the power motor to rotate, and the rotating wheel rotates to be matched with the winding device so that a continuous film can be well placed on the surface of the lower shaping mold; and meanwhile, the thin film can be well cut through the cutter groove and a cutter, and it is guaranteed that the thin film can be well wrapped around the surface of a formed workpiece.

Description

technical field [0001] The invention relates to the field of industrial machinery, in particular to an anti-oxidation powder metallurgy hydraulic forming machine. Background technique [0002] Metal injection molding is a new type of powder metallurgy near-net forming technology derived from the plastic injection molding industry. As we all know, plastic injection molding technology can produce products with various complex shapes at a low price, but the strength of plastic products is not high. In order to improve its properties, metal or ceramic powders can be added to plastics to obtain products with higher strength and good wear resistance. In recent years, this idea has evolved to maximize the content of solid particles and completely Removing the binder and densifying the formed blank, this new powder metallurgy forming method is called metal injection molding, and the powder metallurgy hydraulic forming machine uses a hydraulic device to press the powder into a workpi...
