Abstract
The utility model, which is related to, a kind of prevents the punch structure of returning charge, including drift body, first boss and second boss, it is raised that the upper right corner of the first boss is provided with first, it is raised that the upper left corner of the second boss is provided with second, drift body, first boss and second boss enclose to form groove, and the first boss and second boss are half arcuate structure.The utility model reaches the purpose for preventing waste material from offseting to one side and preventing scrap rising, reduces the defective products quantity caused by returning waste material, effectively prevent the occurrence of pounding mould by setting the projection on drift.
Description
Technical field
The utility model belongs to machined die field, specially a kind of to prevent the punch structure of returning charge.
Background technology
At present, in mold design and production, when the material after punching is pressed into cavity plate by drift, often occurs waste material
The phenomenon offseted to one side, so as to cause scrap rising, causes product appearance undesirable, and is easily caused and pounds mould.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art to prevent the punch structure of returning charge there is provided a kind of.
The utility model solves its technical problem and is achieved through the following technical solutions：
It is a kind of to prevent the punch structure of returning charge, including drift body, first boss and second boss, the first boss
The upper right corner is provided with first raised, and the upper left corner of the second boss is provided with second raised, drift body, first boss and the
Two boss enclose to form groove, and the first boss and second boss are half arcuate structure.
Preferably, first projection and the second projection are inside projection.
Preferably, the groove is rectangle.
Preferably, described first raised and the second raised blistering is highly more than 0.2mm.
The beneficial effects of the utility model, by setting the projection on drift, reaching prevents waste material from offseting to one side and preventing
Only the purpose of scrap rising, reduces the defective products quantity caused by returning waste material, effectively prevent the occurrence of pounding mould.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of bossing.
Structural representation when Fig. 3 is the utility model punching.
Label is described as follows in figure：
1- first is raised；2- first boss；3- drift bodies；4- cavity plates；5- second is raised；6- second boss；7- waste materials.
Embodiment
Below by specific embodiment, the utility model is described in further detail, following examples be it is descriptive, no
It is limited, it is impossible to which protection domain of the present utility model is limited with this.
Prevent the punch structure of returning charge, including drift body 3, first boss 2 and second boss 6, institute as shown in drawings
The upper right corner for stating first boss is provided with the first inside projection 1, and the upper left corner of the second boss is provided with the second of indent
Projection 5, drift body, first boss and second boss enclose to form rectangular groove, the first boss and second boss
For half arcuate structure.First raised and the second projection blistering is highly 0.2mm.
During work, the waste material 7 after punching is pressed into cavity plate 4 by drift, and waste material is due to there is two inside projections to be stuck in
In cavity plate, it is impossible to offset to opposite side, serving prevents the purpose of scrap rising.
Exemplary description is done to the technical solution of the utility model above, it should explanation, do not departed from this skill
In the case of the core of art scheme, any simple deformation, modification or other skilled in the art can not spend creation
Property work equivalent substitution each fall within the protection domain of this patent.
