Technique effect：

Company's punch press tonnage deficiency problem is solved by the utility model and the product quality problem for increasingly improving is met, Current large-sized water turbine generator quality requirement more and more higher, it is desirable to which the precision of punching is just higher, the utility model one-piece parts are few, Simple structure, easy to operate, the stator sector piece teeth portion sulculus punch die precision using research and development is higher, and product matter is met again Amount improves efficiency and also reduces the manufacturing cost of motor again.

Operation principle：

Mould installion on notching press, notching press program is adjusted, when the device is being used punch-die remains reasonable The punching quality gone out of gap can just meet the requirement of product, guider can improve mould and die accuracy, keep between mould Gap is uniform, improves punching precision and the mold use life-span of workpiece, reduces harmful effect of the forcing press to mould and die accuracy, while The time for saving handling mould improves efficiency, and the major advantage of the invention is：Easy for installation, mold work is stable, and outside is not Sharp condition affects little, jet-bedding high precision, efficiency high to the mould.

1. the course of work：

When notching die is started shooting, drift stresses on material, makes material produce the deformations such as elastic compression, bending and stretching, and Lower mould hole is slightly clamp-oned, when drift continues to press people, the stress in material reaches yield limit, and material starts generation plasticity and cuts Shear deformation, it is continuous with drift while because drift, lower intermode have a gap, therefore with the bending and stretcher strain of material Press-in, the deformation extent of material is just continuously increased, hardening aggravation, and resistance of deformation also constantly rises, until the cutting edge of stress concentration When nearby shear fracture line occurs in material, punching resistance of deformation reaches maximum, when drift continues to press people, makes established upper and lower Micro-crack constantly extends to material internal, and when upper and lower crackle meets (rationally, upper and lower crackle overlaps in gap), material is immediately Separation is pulled off, the invention most critical point can make drift and lower die clearance keep constant, improves jet-bedding quality, reduce mould mill Damage.
