Description
Technical field
The utility model relates to mold parts field, particularly relates to a kind of male die for stamping die.
Background technology
Cold punching technology is a kind of cutting highly efficient in productivity, few or the advanced processing method without cutting, all has a lot of advantages in economy and technical elements.It is easy and simple to handle, is convenient to realize mechanization and automation, is suitable for the production of part more in enormous quantities, and its goods generally do not need to make further machining, and dimensional accuracy and interchangeability are also all relatively good.So it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation.In the middle of punching production, diel is as the concrete executing means of Sheet Metal Forming Technology, and natural attention, in fact, the design level of punching die structure and the accuracy of manufacture are the keys ensureing stamped part quality.
In high speed stamping is produced, the rise out of control of stamping and waste material causes serious adverse consequences.The reason of bringing out this phenomenon has a lot, except the inducement increased the weight of in the micro-magnetization of high speed stamping lower punch head, such as resonate with punch press, that lubricating oil is feeding-up or too much, punch enters die be excessively shallow, and gap between punch and die is uneven or punch profile design unreasonable etc. may be all the immediate cause causing stamping or waste material rise out of control.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of male die for stamping die, effectively can prevent the rise of stamping or waste material.
The utility model is achieved through the following technical solutions:
A kind of male die for stamping die, comprise punch body, the upper surface middle position of described punch body offers semi-circular recesses downwards, the arc surface of described semi-circular recesses offers several inclined holes, and one end of described inclined hole terminates in the lateral surface of punch body.
As optimal technical scheme of the present utility model, the radius R of described semi-circular recesses is 2/3 of punch body upper surface radius r.
As optimal technical scheme of the present utility model, the diameter d of described inclined hole is 1-2mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by offering groove and inclined hole on the upper surface of punch, utilizing compressed air that stamping or waste material are separated with punch, improve the result of use of punch die.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-punch body; 2-semi-circular recesses; 3-inclined hole.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of male die for stamping die, comprise punch body 1, the upper surface middle position of described punch body 1 offers semi-circular recesses 2 downwards, the arc surface of described semi-circular recesses 2 offers several inclined holes 3, and one end of described inclined hole 3 terminates in the lateral surface of punch body 1.The utility model structure is simple, reasonable in design, by offering groove and inclined hole on the upper surface of punch, utilizes compressed air that stamping or waste material are separated with punch.
The radius R of described semi-circular recesses 2 is 2/3 of punch body 1 upper surface radius r, and the diameter d of described inclined hole 3 is 1-2mm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
