Abstract
The invention provides a stamping die structure, in particular to a stamping die mechanism which comprises a female die, wherein a female die cutting edge for disengaging scrap is arranged on the female die; and a clamping block, which extends into the female die cutting edge from the lateral edge of the female die cutting edge to clamp the scrap, is also arranged on the female die. Therefore, the phenomenon of scrap bouncing can be avoided effectively.
Description
Technical field
The present invention relates to a kind of punching die structure, but relate in particular to a kind of punching die structure of anti-scrap bouncing.
Background technology
The metalwork of electronic product all is provided with the waste material die cutting hole of shapes such as circular hole, slot in the corresponding diel when carrying out punch forming.Diel is when carrying out high speed stamping production, and waste material falls in the above-mentioned waste material die cutting hole of die after shearing and finishing.But, in punching course, the absorption, the absorption that fluid produces, the magnetic force of punch and the negative pressure that compressed air forms that produce because of vacuum all can cause the waste material of staying in the cutting edge of die (being above-mentioned slug hole) upwards to jump out the phenomenon of falling on the die face, and this phenomenon namely is referred to as to jump bits.Jumping the bits phenomenon can cause scrap and the overlapping extruding of product in the mould and damage product and mould, the product quality when being unfavorable for producing in a large number and the control of production cost.Particularly in the operation process of thin material and high speed stamping, it is particularly evident and outstanding that this kind jumped the bits phenomenon, has a strong impact on the efficient of punching press and the quality of product.
Therefore, be necessary to provide a kind of improved stamping die mechanism to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of punching die structure that can effectively prevent from jumping bits.
For achieving the above object; the invention provides a kind of punching die structure; comprise die, described die is provided with uses the cutting edge of die that breaks away from for waste material, and described die also is provided with in the cutting edge of die lateral margin protrudes into described cutting edge of die to hold the fixture block of waste material.
As a further improvement on the present invention, described fixture block inwardly dwindles gradually from the cutting edge of die lateral margin and forms the dovetail shaped setting.
As a further improvement on the present invention, described fixture block upside is provided with the inclined plane of downward-sloping extension.
As a further improvement on the present invention, described die is provided with respectively opposite side edges from described cutting edge of die and protrudes in opposite directions two described fixture blocks in the cutting edge of die.
As a further improvement on the present invention, described cutting edge of die is horn-like expansion setting from top to bottom.
The invention has the beneficial effects as follows: the present invention is by arranging in the cutting edge of die lateral margin protrudes into described cutting edge of die to hold the fixture block of waste material at described die, thereby so that the cutting edge of die local size is less than waste material profile, and then in punching course, when the punching pin on the punch is squeezed into waste material in the cutting edge of die, waste material is held in the cutting edge of die by fixture block crimp, and final formation gets stuck and effectively prevents from jumping the generation of considering phenomenon to be worth doing.
Description of drawings
Fig. 1 is the stereogram of punching die structure of the present invention and waste material;
Fig. 2 is the cross-sectional schematic of punching die structure among Fig. 1, shows the structure of cutting edge of die.
The specific embodiment
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in protection scope of the present invention.
Please refer to Fig. 1 to a preferred embodiments that Figure 2 shows that punching die structure of the present invention.The punch (not shown) that described punching die structure comprises die 1 and matches with die 1.Described die 1 is provided with to use for the cutting edge of die 11 of waste material 8 disengagings and from described cutting edge of die 11 lateral margins and protrudes into the fixture block 12 to hold waste material 8 in the described cutting edge of die 11.Described fixture block 12 inwardly dwindles gradually from cutting edge of die 11 lateral margins and forms the dovetail shaped setting.The size at described cutting edge of die 11 interior fixture blocks 12 positions is less than the corresponding appearance and size of described waste material 8, thereby can be trapped in fixture block 12 positions so that waste material 8 pushes at cutting edge of die 11 interior quilts when mobile downwards.Described cutting edge of die 11 is horn-like expansion setting from top to bottom, thereby makes things convenient for waste material 8 to flee from cutting edge of die 11 downwards.Described fixture block 12 upsides are provided with the inclined plane 121 of downward-sloping extension, thus the punching pin on punch (not shown) cut downwards and extrusional slug 8 processes in, can prevent that punching pin from running into swallow-tailed described fixture block 12 and rupture.
In the present invention, described die 1 is provided with respectively opposite side edges from described cutting edge of die 11 and protrudes in opposite directions two described fixture blocks 12 in the cutting edge of die 11.
Got by above, the present invention is by arranging the fixture block 12 to hold waste material 8 in cutting edge of die 11 lateral margins protrude into described cutting edge of die 11 at described die 1, thereby so that cutting edge of die 11 local sizes are less than waste material 8 profiles, and then in punching course, punching pin on the punch is squeezed into cutting edge of die 11 when interior with waste material 8, waste material 8 can be held in the cutting edge of die 11 by fixture block 12 crimps, and final formation gets stuck and effectively prevents from jumping the generation of considering phenomenon to be worth doing.
Be to be understood that, although this specification is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each embodiment also can through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility embodiment of the present invention; they are not to limit protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill spirit of the present invention does and all should be included within protection scope of the present invention.
