Problems solved by technology
[0004] At present, most of the domestic anti-extrusion machines are imported equipment, and the mold unloading and mold loading devices used in them all adopt the in-machine mode, that is, the mold unloading and mold loading devices are designed inside the main machine, and they are all operated by manipulators. Complex, although the control precision is high, but the cost is high and maintenance is difficult

The invention relates to a die filling device for the inverted extrusion equipment, in particular to an auxiliary equipment for the nonferrous metal extrusion equipment. Since the prior die filling device of the inverted extrusion equipment is arranged inside a mainframe and is operated through a manipulator, thus the prior die filling device has the disadvantages of complicated structure, difficult maintenance and high construction cost. The invention is characterized in that: the die filling device is arranged at the outer end of the extrusion rod of the inverted extrusion equipment; a driving shaft and a driven shaft are arranged on a bracket to support a die; the driving shaft is driven to rotate by an oil motor arranged on the bracket; a positioning block is connected with the bracket through a spacer and can be contacted with the die, and an oil cylinder is arranged above the bracket and connected with a pusher, which can push the die to be assembled on the extrusion rod. Compared with the prior art, the invention has the advantages of novel and simple structure, easy maintenance, strong practicability and low construction cost.
Description
technical field [0001] The invention relates to a non-ferrous metal extruder, in particular to an auxiliary device for a reverse extruder. Background technique [0002] The reverse extrusion method is a metal extrusion processing method in which the direction of metal flow is opposite to the forward direction of the extrusion rod. Its main feature is that there is no relative movement between the extrusion cylinder and the ingot. The reverse extrusion method is more and more used in actual metal extrusion processing. Compared with the forward extrusion method, it has the following advantages: (1) Since there is no friction between the ingot and the extrusion cylinder, the extrusion force Much lower than with forward extrusion. (2) The metal deformation is uniform, and the structure and mechanical properties along the length direction of the extruded product are basically the same. (3) There is less loss of waste materials such as overpressure, and a higher yield; larger in...
