Abstract
The utility model relates to a kind of diel fender and to go up device, comprise punch body, described punch body offers shoulder hole in the axial direction, by screw thread pair, stud is installed in the bottom of shoulder hole, the bottom of described stud flushes with the bottom of punch body, and stud is provided with spring, one end contact jigger pin of described spring, the top of described jigger pin is semi-cylindrical hill, offers several blind holes downwards on the top of jigger pin.The utility model structure is simple, reasonable in design, by being provided with elasticity jigger pin on punch, elastic force can being utilized effectively to prevent the rise of stamping or waste material, improve the result of use of diel; The head design of jigger pin becomes semicircle and offers blind hole simultaneously, effectively avoids, because of stamping surface and the head contact place compressed air of jigger pin, causing stamping or scraps rising back.
Description
Technical field
The utility model relates to mold parts field, particularly relates to a kind of diel fender and to go up device.
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.The measure of pre-fender of the prior art or waste material is very unreasonable, needs further improvement and perfection.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of diel fender and to go up device, effectively can prevent the rise of stamping or waste material.
The utility model is achieved through the following technical solutions:
A kind of diel fender is gone up device, comprise punch body, described punch body offers shoulder hole in the axial direction, by screw thread pair, stud is installed in the bottom of shoulder hole, stud is provided with spring, one end contact jigger pin of described spring, the top of described jigger pin is semi-cylindrical hill, offers several blind holes downwards on the top of jigger pin.
As optimal technical scheme of the present utility model, the top length of the top distance punch body of described jigger pin is 5mm.
As optimal technical scheme of the present utility model, the bottom of described stud flushes with the bottom of punch body.
As optimal technical scheme of the present utility model, described blind hole is circular hole, and its diameter is 1mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with elasticity jigger pin on punch, elastic force can being utilized effectively to prevent the rise of stamping or waste material, improve the result of use of diel; The head design of jigger pin becomes semicircle and offers blind hole simultaneously, effectively avoids, because of stamping surface and the head contact place compressed air of jigger pin, causing stamping or scraps rising back.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-punch body; 2-shoulder hole; 3-stud; 4-spring; 5-jigger pin; 6-semi-cylindrical hill; 7-blind 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 diel fender is gone up device, comprise punch body 1, described punch body 1 offers shoulder hole 2 in the axial direction, by screw thread pair, stud 3 is installed in the bottom of shoulder hole 2, stud 3 is provided with spring 4, one end contact jigger pin 5 of described spring 4, the utility model structure is simple, reasonable in design, by being provided with elasticity jigger pin on punch, elastic force can being utilized effectively to prevent the rise of stamping or waste material, improve the result of use of diel.
The top of described jigger pin 5 is semi-cylindrical hill 6, offers several blind holes 7 on the top of jigger pin 5 downwards, effectively avoids, because of stamping surface and the head contact place compressed air of jigger pin, causing stamping or scraps rising back.
The top length of the top distance punch body 1 of described jigger pin 5 is 5mm, and the bottom of described stud 3 flushes with the bottom of punch body 1, and described blind hole 7 is circular hole, and its diameter is 1mm.
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.
