Abstract
The utility model relates to a kind of plastic material bending apparatus, comprises body of punch, plastic material plate, die body, and described plastic material plate is provided with plastic material plate pad, and the centre position, top of described plastic material plate offers relief groove downwards; Billet is provided with at the bottom of the hole of described die body, the upper surface of described billet is curved surface, rod iron is encased inside in the both sides of billet, described rod iron is tangent with the top of die body, baffle plate, plastic material plate respectively, form cavity between described plastic material plate and billet, the radius of curvature of described billet upper surface equals radius of curvature and the plastic material plate mat thickness sum of plastic material plate drip molding.Cavity is formed between plastic material plate of the present utility model and billet, to reduce plastic material plate pressure during bending forming, by setting up billet, the upper surface of billet is curved surface, can ensure that the plastic force on whole curved surface is uniform, offer relief groove by the top of plastic material plate, thus increase the lateral pressure in being shaped, be conducive to eliminating resilience, improve quality and the dimensional accuracy of workpiece.
Description
Technical field
The utility model relates to machine die manufacturing technology field, particularly relates to a kind of plastic material bending apparatus.
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 carried out with plastic material bending die, usually the appearance frame of a steel punch (or die) and an installation polyurethane plasticity plate of material is only had, structure is 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 with plastic material bending die, the forming pressure size of plastic material plate 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 plastic material bending apparatus.
The utility model is achieved through the following technical solutions:
A kind of plastic material bending apparatus, comprise body of punch, plastic material plate, die body, described plastic material plate is provided with plastic material plate pad, and the centre position, top of described plastic material plate offers relief groove downwards; Billet is provided with at the bottom of the hole of described die body, the upper surface of described billet is curved surface, be encased inside rod iron in the both sides of billet, described rod iron is tangent with the top of die body, baffle plate, plastic material plate respectively, forms cavity between described plastic material plate and billet.
As optimal technical scheme of the present utility model, the lower end of described body of punch is provided with ribs, and the lower surface of described ribs is arc surface.
As optimal technical scheme of the present utility model, described baffle plate is arranged on billet.
As optimal technical scheme of the present utility model, the radius of curvature of described billet upper surface equals radius of curvature and the plastic material plate mat thickness sum of plastic material plate drip molding.
Compared with prior art, the beneficial effects of the utility model are: form cavity between plastic material plate of the present utility model and billet, to reduce plastic material plate pressure during bending forming, by setting up billet, the upper surface of billet is curved surface, can ensure that the plastic force on whole curved surface is uniform, relief groove is offered by the top of plastic material plate, thus increase the lateral pressure in being shaped, be conducive to eliminating resilience, improve quality and the dimensional accuracy of workpiece.
