(Summary description)
Extruder equipment is becoming more and more popular in enterprises. When selecting the extruder equipment, in addition to considering the thermal influence of the extrusion speed on the extruded metal, it should also be considered that the press should have sufficient rigidity and guiding accuracy, and a reliable overload protection device should be installed. When the friction press is used for extrusion, due to the different guiding accuracy of the equipment, it is necessary to install a guiding device on the mold. For friction presses without ejector, jacking devices should also be added. When pressing with a universal crank press, in order to improve the strength and rigidity of the equipment, the bottom plate of the worktable should be made of cast steel, and the holes on the worktable should be reduced. Since the parts remain on the die after extrusion, the tension between the extruded part and the die is relatively large, and the required ejection amount is relatively large, about 10%-20% of the nominal pressure. Therefore, the pressure setting value exit device should be strengthened. In addition, the extrusion pressure and stroke should be checked according to the allowable load curve of the press slide. That is, in the entire extrusion stroke range, the extrusion pressure should be less than the limit value of the stroke pressure curve allowed by the press, and cannot be determined by the nominal pressure.
The accuracy and stroke of the press are not enough, and the pressure in the middle of the stroke is only about 1/3 of the nominal pressure. Therefore, it is best to use a dedicated extruder as the extrusion equipment. The toggle extruder has the characteristics of small stroke, multiple strokes and long compression time, and is suitable for the extrusion of parts with short working strokes. The utility model is suitable for the extrusion of long parts. The full stroke of the hydraulic extruder works under the nominal pressure, and the extrusion speed and stroke are adjustable, which is suitable for extruding parts with larger lengths.
The working principle of extruder equipment is the principle of physical deformation. The aluminum bar is heated to about 450°C through auxiliary equipment such as electromagnetic heating furnace or coil induction heating furnace, and then extruded through an extruder. The working principle of the extruder is to extrude the aluminum rod heated by the device in the cylinder, and one end is an extrusion rod that outputs the propulsion force. The other end is the corresponding mold. Under the pressure output of the hydraulic system, the extrusion rod pushes the aluminum bar to the die. After high-temperature physical deformation, the aluminum bar emerges from the mold and becomes the corresponding aluminum profile. Then cool and saw the next process.
