Description

Technical Field

[0001] The invention belongs to extruder assembly technology, and in particular relates to a tension column auxiliary installation tool, an extruder and an installation method. Background Art

[0002] Extrusion presses are essential equipment for producing light alloy (aluminum, copper, and magnesium alloy) tubes, bars, and profiles. Metal extrusion is a key method of forming metals using plastic pressure. Its key feature is that it can process metal ingots into tubes, bars, and profiles in an instant, a feat that few other methods can rival.

[0003] As we all know, during installation, the ends of the extruder tension column need to be inserted into the locating holes of the front and rear beams. Due to the constant concentricity deviation of the locating holes of the front and rear beams, and the minimum clearance of less than 0.5mm at the minimum fit, jamming is inevitable during installation due to concentricity issues. When the friction is too great, workers generally use a crane to hit the iron pier to push the end of the tension column through the installation hole. However, this impact will inevitably cause dents on the ends and scratches caused by inaccurate impact in the center. Inappropriate operation can even damage the threads of the head, making it impossible to tighten the nut. Summary of the Invention
