Abstract

The invention relates to a novel precision correcting mechanism of a punching machine. The novel precision correcting mechanism comprises an upper template, a lower template, a guide pillar arranged between the upper template and the lower template, and a guide sleeve arranged on the guide pillar in a sleeving mode; a first cooling oil flow guide channel and a second cooling oil flow guide channel are arranged in the guide pillar; the first cooling oil flow guide channel and the second cooling oil flow guide channel communicate through a connecting hole; the guide pillar is provided with a cooling oil inlet and a cooling oil outlet which are connected with the first cooling oil flow guide channel or the second cooling oil flow guide channel; and a cooling oil machine is connected between the cooling oil inlet and the cooling oil outlet. Cooling oil guided in from the cooling oil inlet flows back into the first cooling oil flow guide channel and the second cooling oil flow guide channel while lubricating the guide pillar and the guide sleeve, the flowing cooling oil takes away friction heat, meanwhile, a cooling effect is achieved, thermal deformation is controlled, the operation stability of the guide sleeve is improved, and after being cooled by the cooling oil machine, the oil enters the flow guide channels through the cooling oil inlet, so that the circulating cooling effect is achieved.

Description

technical field [0001] The invention relates to the field of precision deep drawing stamping, in particular to a novel precision correction mechanism for a punching machine. Background technique [0002] Generally, the vertical accuracy in the conventional stamping process is guaranteed by the vertical accuracy of the slide block guide rail of the punch press and the vertical accuracy of the guide post and guide sleeve of the mold. When the accuracy of the slider of the punching machine is certain, the accuracy of the guide post and guide sleeve of the mold has a great influence on the stamping accuracy, especially in the field of precision deep drawing stamping, the side wall of the drawn product has thinning requirements, and different sections have different thickness requirements . If the verticality of stamping is not good, the metal will flow in an irregular "S" shape, and the thickness of the section will be inconsistent. [0003] At present, the structure of the gu...
