Abstract

The utility model discloses an automobile lifting hook U-shaped bend forming die with turning plates. The automobile lifting hook U-shaped bend forming die comprises a bending male die and a female die. The left edge and the right edge of the top of a hole cavity of the male die are respectively provided with a turning plate. A bend forming stress area of a machining workpiece is increased due to the fact that the turning plates are additionally arranged, acting pressure exerted by the die on the surface of the machining workpiece is reduced, and scratch caused by friction and loss of the die are effectively reduced. Circular arc-shaped grooves are formed in the upper surfaces of the turning plates, the stress area of the machining workipece with the circular cross section is further increased, pressure is reduced, and the occurrence that the machining workpiece is pressurized, flattened and deformed in the process of forming is effectively avoided.

Description

A kind of automobile suspension hook U-shaped bending forming mould with tipping platform
Technical field
The utility model relates to the mold machining technology field, is specifically related to a kind of automobile suspension hook U-shaped bending forming mould.
Technical background
In the U-shaped like bending forming mould process such as automobile suspension hook, the bending forming stress point of workpiece concentrates on the die entrance place, because the too small pressure that causes of lifting surface area is bigger, therefore be difficult to avoid die that the workpiece extrusion friction is caused scratch, even cause workpiece to be out of shape, not only influenced mechanical strength, the outward appearance of workpiece, and extrusion friction is serious for the loss of mould itself.In order to alleviate of the harmful effect of above-mentioned extrusion friction, be necessary existing bending forming mould process technology is proposed improvement project for the processing of bending forming mould.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile suspension hook U-shaped bending forming mould, by increasing the bending forming lifting surface area of workpiece, can effectively alleviate extrusion friction in the bending forming mould process and squeeze scratch and the distortion that causes, and prolong the service life of bending forming mould to workpiece.
To achieve these goals, the technical scheme that the utility model proposes is:
Automobile suspension hook U-shaped bending forming mould comprises crooked punch, die, and described die vestibule top left right hand edge respectively is provided with a turnover panel.By increasing turnover panel, the bending forming lifting surface area of workpiece is increased, so mould reduce for the effect pressure of work piece surface, effectively having alleviated the scratch that friction causes and the loss of mould itself.
As the further improved automobile suspension hook U-shaped bending forming mould of the utility model, also comprise upper bolster, die shoe, two guide pillars and guide pin bushing, described guide pillar and guide pin bushing are fixedly arranged on the die shoe two ends, and described guide pillar and guide pin bushing and upper bolster flexibly connect, described upper bolster can be moved up and down along guide pillar and guide pin bushing direction, described crooked punch upper end is fixedly arranged on described upper bolster bottom, and described die lower end is fixedly arranged on described die shoe top.
As the further improved automobile suspension hook U-shaped bending forming mould of the utility model, described turnover panel upper surface is provided with circular groove.Circular groove can avoid the situation that add flattened distortion of the circular workpiece in cross section in forming process to take place effectively, and can further increase lifting surface area, reduces pressure.
As the further improved automobile suspension hook U-shaped bending forming mould of the utility model, the vestibule of described die bottom is provided with through hole, is provided with spring and discharging bolt in the described through hole, and described discharging bolt is positioned at the spring top.
Automobile suspension hook U-shaped bending forming mould provided by the utility model, by die vestibule top left right hand edge turnover panel is set, and circular groove is set at the turnover panel upper surface, the pressure of mould action on workpiece when having reduced bending forming, can effectively alleviate extrusion friction in the bending forming mould process and squeeze scratch and the distortion that causes, and prolong the service life of bending forming mould to workpiece.

The specific embodiment
In order to deepen to understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Shown in Fig. 1-3, the automobile suspension hook U-shaped bending forming mould that present embodiment provides comprises crooked punch 4, die 5, and described die 5 vestibule top left right hand edges respectively are provided with a turnover panel 6.Further, described turnover panel 6 upper surfaces are provided with circular groove.During work, workpiece is positioned on the vestibule of die 5, punch 4 moves downward, workpiece is moved in die 5 vestibules, punch 4 bends workpiece with die 5 actings in conjunction, in and the process of in die 5 vestibules, moving crooked at workpiece, workpiece and die 5 fillet places realize bending forming by turnover panel, the pressure of mould action on workpiece is less, effectively alleviated the damage of scraping of workpiece that sliding friction causes and mould, and turnover panel 6 upper surfaces are provided with circular groove has further increased lifting surface area, has reduced pressure, has effectively avoided the situation of the flat distortion of workpiece to take place.
Further, described automobile suspension hook U-shaped bending forming mould, also comprise upper bolster 1, die shoe 2, two guide pillars and guide pin bushings 3, described guide pillar and guide pin bushing 3 are fixedly arranged on die shoe 2 two ends, and described guide pillar and guide pin bushing 3 flexibly connect with upper bolster 1, described upper bolster 1 can be moved up and down along guide pillar and guide pin bushing 3 directions, and described crooked punch 4 upper ends are fixedly arranged on described upper bolster 1 bottom, and described die 5 lower ends are fixedly arranged on described die shoe 2 tops.Upper bolster 1, die shoe 2, guide pillar and guide pin bushing 3 have been realized the steady and accurate of Mould Machining process.
Further, the vestibule of described die 5 bottom is provided with through hole, is provided with spring 7 and discharging bolt 8 in the described through hole, and described discharging bolt 8 is positioned at spring 7 tops.After bending forming machines, punch 4 upwards liftings, workpiece withdraws from the vestibule of die 5 automatically under the effect of spring 7 and discharging bolt 8.
