Equipment for forwardly and backwardly extruding production hubs

The utility model discloses equipment which is used by hubs made of magnesium alloy, aluminum alloy and other metals and is used for forwardly and backwardly extruding production hubs. The equipment is characterized in that upright posts (2) are arranged at the middle parts of a machine base (1) and a fixed plate (3) to form a machine frame; an extruder moving plate (4) is movably placed on the upright posts (2); a hydraulic system is arranged on the machine frame; an extrusion cylinder forming mechanism is arranged at the lower middle part of the extruder moving plate (4); and an ejecting mechanism and a workpiece taking mechanism (13) are arranged at the inner middle part of the machine base (1). The equipment has the beneficial effects that as special extrusion equipment and a scientific preparation method are designed, a preheated metal blank is placed into an extrusion cylinder to be formed by one-time extrusion, so that the mechanical performance of a product is high, and the demands of high-performance
