[0002] The raw materials of thin-walled high-strength precision aluminum alloy pipes are extruded tube blanks made of thick-walled hard aluminum or super-hard aluminum alloys. Due to the poor extrusion processability of hard aluminum or super-hard aluminum alloys, their wall thickness is relatively large, and they need to be drawn and deformed during the high-precision aluminum alloy pipe forming process. For example, as shown in a compact hydraulic drawing machine with Chinese patent application number CN202020258791.9, a sliding portion is provided on the sliding plate, and a hook is hinged at the front end of the sliding portion for pulling out the tube core in the bent pipe. A fixing part is provided on the sliding plate, and the fixing part is located downstream of the sliding part. The spring guide rod is arranged downstream of the fixing part. The spring guide rod includes a sleeve and a piston rod that is horizontally slidably connected to the sleeve. The piston rod extends along the direction of pulling out the tube core and is connected to the fixing part. A return spring is mounted on the piston rod.
