Detailed description of the invention
In order to understand better the present invention, further illustrate content of the present invention below in conjunction with embodiment, but content of the present invention is not only confined to the following examples.
A kind of fine-punching formation slides and combines navigation designing method with rolling high accuracy, comprises the steps:
1) for slide-and-guide, guiding mechanism is arranged on smart impact machine, specifically designs at the slide block of smart impact machine and guide rail guiding 1, master cylinder 2 two parts that lead;
Slide block and guide rail targeting part in smart impact machine, the fit clearance of slide block and guide rail is designed to 5～20 μ m, owing to breaking through in journey in essence, on feed direction, be prone to unbalance loading most, so guide rail (101) length in opposing feed direction unbalance loading is set as (L+400) mm according to smart impact machine punching stroke, wherein L is smart impact machine punching stroke; On perpendicular to feed direction, the length of the guide rail (103) of vertical feed direction can be set as (L+100) mm (its length can be slightly short, and wherein L is smart impact machine punching stroke);
