Abstract
The invention discloses a U-shaped bend forming die of a car lifting hook with pulleys. The U-shaped bend forming die of the car lifting hook with the pulleys comprises a curved convex die and a curved concave die, wherein a pulley is respectively arranged at the left edge and the right edge of the top part of a hole cavity of the concave die. The sliding friction between a processed member and a rounded corner of the concave die in the prior art is changed into rolling friction through the addition of the pulleys. Therefore, the U-shaped bend forming die of the car lifting hook with the pulleys not only improves flowing properties of a material, but also efficiently lightens scratching damage caused by the friction and wastage of the die per se.
Description
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.
Technical background
In the U-shaped like bending die process such as automobile suspension hook, be difficult to avoid die that the workpiece extrusion friction is caused scratch even cause workpiece distortion, 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, 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 pulley.By increasing pulley, the sliding friction at workpiece and die entrance place has been transformed into rolling friction in the prior art, has not only improved the mobile performance of material, the scratch that effectively having alleviated simultaneously rubs 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 pulley flanks is concave arc shape structure.Arc-shaped structure can avoid the situation that add flattened distortion of the circular workpiece in cross section in forming process to occur effectively.
As the further improved automobile suspension hook U-shaped bending die of the present invention, described die vestibule 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, replace sliding friction by rolling friction, and pulley flanks is designed to concave arc shape structure, not only improved the mobile performance of material, and 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. 1-2, 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 pulley 6.Further, described pulley 6 sides are concave arc shape structure.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 have realized rolling friction by pulley, effectively alleviated the damage of scraping of workpiece that sliding friction causes and mould, and pulley 6 sides are that concave arc shape structure has also 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, described die 5 vestibules 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.
