Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a moving guiding mechanism for a precision stamping die. Background Technique

[0002] Stamping is a processing method that uses a die installed on a press to apply pressure to a material to cut or stretch and deform it. To ensure that the impact block of the moving die can perfectly cooperate with the impact groove of the fixed die, a mutually cooperating guide rod and guide sleeve are usually arranged between the moving die and the static die. Since the guide rod and the guide sleeve are only simply inserted and matched, lubricating oil needs to be added. Otherwise, the mating part of the guide rod and the guide sleeve will wear, resulting in jamming or even seizure of the guide rod and the guide sleeve, reducing the service life of the stamping die.

[0003] However, the existing moving guiding mechanism requires operators to frequently manually apply lubricating oil, and this process requires shutdown operation, which greatly affects production efficiency. Moreover, impurities often adhere or adsorb to the guide rod. If not cleaned in time, it will damage the guide rod during the stamping process. Content of the Utility Model
