Broad mass market, our company finds in the research and development of high power feedthrough frame stamping die, either pass by or present, high speed grade
" the jumping bits " of progressive die is always the problem for enabling design and producing personnel worries.So-called " jumping bits " refers in mold production process
In, the phenomenon that should decline from the cavity plate edge of a knife crumble that go down or product but with punch-pin jump out die face because of various reasons.
Utility model content
The utility model be directed to above-mentioned problem, provide it is a kind of prevented in punching press processing procedure leftover bits and pieces backfill or jump bits
Novel blade.
In order to achieve the above object, the technical solution adopted in the utility model is that the utility model provides one kind in punching press
It prevents leftover bits and pieces from backfilling in processing procedure or jumps the novel blade of bits, including blade main body, the side of the blade main body are provided with knife
Blade surface is provided with S type inclined groove in the blade face；
The inclined angle alpha of the S type inclined groove is 5 ° -10 °；
The S type inclined groove is semi-circular groove；
The S type inclined groove includes the semi-circular groove in top, lower semicircular type groove and is arranged on top
S type bending slot between semi-circular groove and lower semicircular type groove；
It is provided with semicircular ring protrusion in the semi-circular groove in top, is provided in the lower semicircular type groove
Semicircle ring groove.
Preferably, the number of the semicircular ring protrusion is 2-4, the distance between two of them semicircular ring protrusion is
1mm-2mm。
Preferably, the number of the semicircle ring groove is 2-3, the distance between two of them semicircle ring groove is
0.8-1.5mm。
Preferably, the number of the bending point of the S type bending slot is 5-8.
Compared with prior art, it is the advantages of the utility model with good effect,
1, the utility model design is easy to process, and does not influence the replacement of die change and product type, and structure is simple, nothing
Excessive cost and modification time need to be expended.This technology reduces frequency of maintenance and the time of stamping die, greatly improves production effect
Rate creates more economic benefits.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical solution of the utility model embodiment

Specific embodiment
It is with reference to the accompanying drawing and real in order to be more clearly understood that the above objects, features, and advantages of the utility model
Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality
The feature applied in example can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as Figure 1-Figure 2, the utility model provide prevented in a kind of punching press processing procedure leftover bits and pieces backfill or
The novel blade for jumping bits, from figure can, novel blade includes blade main body, and the side of the blade main body is provided with blade
Face, S type inclined groove is provided in blade face due to the setting of the S type inclined groove makes the leftover bits and pieces generated in punching course
Expect to generate small burr in the corresponding position of anti-scrap bouncing groove, increases the coefficient of friction and pressure of leftover bits and pieces and DIES, make the two
Between frictional force increase, thus realize prevent leftover bits and pieces backfill or jump bits, it is noted herein that: the depth of groove and tiltedly
Degree is set according to the length of the thickness of punching material and Blank cutting-edge.
Inventor show that the inclined angle alpha of S type inclined groove is 5 ° -10 ° by a large amount of test, only inclination angle
Angle can just play the role of small burr when above-mentioned angle, it is too small not, it is excessive, can generate bigger
Burr；
Its S type inclined groove is semi-circular groove, and the design of semi-circular grooves also can be in order to enable crumble out of groove
Preferably pass through；
Inventor is better in order to make to jump bits effect, therefore S type inclined groove has been carried out further setting, that is, includes upper
The semi-circular groove in portion, lower semicircular type groove and the S type being arranged between the semi-circular groove in top and lower semicircular type groove
Bending slot is the setting that is connected smoothly between the semi-circular groove of upper part, lower semicircular type groove and S type bending slot
's；Inventor is provided with semicircular ring in the semi-circular groove in top to enable S type inclined groove to reach better volume effect
Protrusion is provided with semicircle ring groove in lower semicircular type groove.
Other than above-mentioned design, inventor is also concluded that by a large amount of test
The number of semicircular ring protrusion is 2-4, and the distance between two of them semicircular ring protrusion is 1mm-2mm；
The number of semicircle ring groove is 2-3, and the distance between two of them semicircle ring groove is 0.8-1.5mm；
The number of the bending point of S type bending slot is 5-8
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation is applied to other fields, but all without departing from the content of the technical scheme of the utility model, according to this reality
With novel technical spirit any simple modification, equivalent variations and remodeling to the above embodiments, it is practical new to still fall within this
The protection scope of type technical solution.
