Description

Technical Field

[0001] The utility model relates to the technical field of forging processing, in particular to a forging CNC lathe. Background Art

[0002] A forging is a workpiece or blank obtained by forging and deforming a metal blank. Forgings are categorized by cold forging, warm forging, and hot forging, depending on the temperature of the blank during processing. Forgings require the use of a CNC lathe.

[0003] The prior art discloses an improved CNC lathe, disclosed in CN208600714U, comprising a permanent magnet servo motor, a three-phase power supply circuit, a short-circuit closure circuit, a switch, and a brake controller. When the permanent magnet servo motor loses power, the brake controller controls the switch to disconnect the three-phase power supply circuit and simultaneously controls the switch to connect the short-circuit closure circuit. This puts the permanent magnet servo motor in a short-circuit state, applying a reverse force to the motor's coils. This reverse force causes the motor's output shaft to rotate in the opposite direction to the lead screw, preventing the moving parts from sliding downward.

[0004] When processing forgings, today's forging CNC lathes insert the forgings into the mounting frame. However, the forgings to be processed may also be annular and cannot be inserted into the mounting frame, making them difficult to process. Utility Model Content

By arranging the limit rod on one side of the support rod and the mounting frame, it is convenient to connect the rotating frame.

[0010] Preferably, the outer end face of one side of the outer rod is movably connected to the inner rod, and the outer end face of one side of the inner rod is fixed with a connecting plate. By arranging the inner rod and the connecting plate on the outer end face of one side of the outer rod, it is convenient to fix the annular forging.

[0011] Preferably, a fixing plate is welded to one outer end surface of the connecting rod, and a clamping plate is fixed to the other outer end surface of the connecting rod.
