Abstract
The utility model relates to a kind of bending mould, comprises body of punch, rubber, die body, and the lower end of described body of punch is provided with ribs, and the lower surface of described ribs is arc surface, and the centre position, top of described rubber offers relief groove downwards; Offer cavity in described die body, described rubber is installed in the cavities, is lined with rod iron at every side-lower of rubber; The top of described die body offers deep-slotted chip breaker.The utility model, by arranging rod iron, can ensure that the plastic force on whole curved surface is uniform, offer relief groove by the top of rubber, thus increases the lateral pressure in being shaped, and is conducive to eliminating resilience, improves quality and the dimensional accuracy of workpiece.
Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of bending mould.
Background technology
Bending process is the needs according to part shape, by mould and forcing press, blank is curved certain angle, the Sheet Metal Forming Technology method of definite shape workpiece, its application is quite extensive, as automobile much carries out cover piece, the tank bracket component of car, handle on motorcycle, foot support, support element on bicycle, handle, little of knocker, clip (iron clamp) etc.Sheet metal bending is being carried out with bending die, usually only have a steel punch (or die) and one that the appearance frame of rubber is installed, structure be simple, highly versatile, low cost of manufacture, bool springback angle and bending radius, than all less time bending in metal die, thus demonstrate many advantages.But when using bending die, the forming pressure size of rubber blanket is not easy to regulate on the one hand, and forming pressure skewness, reduces quality and the dimensional accuracy of drip molding on the other hand.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of bending mould.
The utility model is achieved through the following technical solutions:
A kind of bending mould, comprise body of punch, rubber, die body, the lower end of described body of punch is provided with ribs, and the centre position, top of described rubber offers relief groove downwards; Offer cavity in described die body, described rubber is installed in the cavities, is lined with rod iron at every side-lower of rubber; The top of described die body offers deep-slotted chip breaker.
As optimal technical scheme of the present utility model, the lower surface of described ribs is arc surface.
As optimal technical scheme of the present utility model, described relief groove is square groove.
As optimal technical scheme of the present utility model, the quantity of every side rod iron is two.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by arranging rod iron, can ensure that the plastic force on whole curved surface is uniform, relief groove is offered by the top of rubber, thus increase the lateral pressure in being shaped, be conducive to eliminating resilience, improve quality and the dimensional accuracy of workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-body of punch; 2-rubber; 3-die body; 4-rod iron; 5-deep-slotted chip breaker; 10-ribs; 20-relief groove; 30-cavity.
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 bending mould, comprises body of punch 1, rubber 2, die body 3, and the lower end of described body of punch 1 is provided with ribs 10, and the centre position, top of described rubber 2 offers relief groove 20 downwards; Offer cavity 30 in described die body 3, described rubber 2 is arranged in cavity 30, is lined with rod iron 4 at every side-lower of rubber 2; The top of described die body 3 offers deep-slotted chip breaker 5.The utility model, by arranging rod iron, can ensure that the plastic force on whole curved surface is uniform, offer relief groove by the top of rubber, thus increases the lateral pressure in being shaped, and is conducive to eliminating resilience, improves quality and the dimensional accuracy of workpiece.
The lower surface of described ribs 10 is arc surface, and described relief groove 20 is square groove, and the quantity of every side rod iron 4 is two.
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.
