Abstract

The invention discloses a U-shaped bend forming die of a car lifting hook with turning plates. The U-shaped bend forming die comprises a curved convex die and a curved concave die, wherein a turning plate is respectively arranged at the left edge and the right edge of the top part of a hole cavity of the concave die. The bend forming stressed area of a processed member is enlarged through the addition of the turning plates, so that functional pressure intensity from the die to the surface of the processed member is reduced, and scratching damage caused by friction and wastage of the die per se are lightened efficiently. As an arc groove is arranged on the upper surface of each turning plate, the stressed area of the processed member with a round section is further enlarged, the pressure intensity is reduced, and flat deformation caused by pressing of the processed member in the forming process is avoided efficiently.

Description

A kind of automobile suspension hook U-shaped bending die with tipping platform
Technical field
The present invention relates to the mold machining technology field, be specifically related to a kind of automobile suspension hook U-shaped bending die.
Background technology
In the U-shaped like bending die 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 larger, therefore be difficult to avoid die that the workpiece extrusion friction is caused scratch, even cause workpiece to be out of shape, not only affected mechanical strength, the outward appearance of workpiece, and extrusion friction is serious for the loss of mould itself.In order to alleviate above-mentioned extrusion friction for the harmful effect of bending die processing, be necessary existing bending die process technology is proposed improvement project.
Summary of the invention
The object of the present invention is to provide a kind of automobile suspension hook U-shaped bending die, by increasing the bending forming lifting surface area of workpiece, can effectively alleviate extrusion friction in the bending die process and squeeze scratch and the distortion that causes to workpiece, and prolong the service life of bending die.
To achieve these goals, the technical scheme of the present invention's proposition is:
Automobile suspension hook U-shaped bending die comprises crooked punch, die, and described die hole top of chamber left and right edges 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 scratch that friction causes and the loss of mould itself.
As the further improved automobile suspension hook U-shaped bending die of the present invention, 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 are flexibly connected, 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 die of the present invention, 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 occur effectively, and can further increase lifting surface area, reduces pressure.
As the further improved automobile suspension hook U-shaped bending die of the present invention, 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 die provided by the present invention, by die hole top of chamber left and right edges turnover panel is set, and at the turnover panel upper surface circular groove is set, the pressure of mould action on workpiece when having reduced bending forming, can effectively alleviate extrusion friction in the bending die process and squeeze scratch and the distortion that causes to workpiece, and prolong the service life of bending die.

The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention is done to describe in further detail, this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Shown in Fig. 1-3, the automobile suspension hook U-shaped bending die 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 moving in die 5 vestibules 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 occur.
Further, described automobile suspension hook U-shaped bending die, also comprise upper bolster 1, die shoe 2, two guide pillars and guide pin bushing 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 are flexibly connected 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.
