Abstract
An automobile lifting hook U-shaped bend forming die with pulleys 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 female die are respectively provided with a pulley. The automobile lifting hook U-shaped bend forming die with the pulleys further comprises an upper die base, a lower die base, two guiding column and guide sleeves, wherein the guiding column and guide sleeves are fixedly arranged at two ends of the lower die base and are movably connected with the upper die base. The upper die base can move up and down along the direction of the guide column and guide sleeves, the upper end of the bending male die is fixedly arranged on the bottom of the upper die base, and the lower end of the female die is fixedly arranged on the top of the lower die base. The side face of each pulley is of a concave circular arc-shaped structure. A through hole is formed on the bottom of a hole cavity of the female die. A spring and a discharging bolt are arranged in the through hole. The discharging bolt is located above the spring. A flowing property of materials is improved, and scratch and deformation of a machining workpiece caused by extrusion friction in the process of machining of the bend forming die are effectively reduced, and the service life of the bend forming die is prolonged due to the facts that sliding friction is replaced by rolling friction, and the side face of each pulley is designed to be of the concave circular arc-shaped structure.
Description
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, be difficult to avoid die that the workpiece extrusion friction is caused scratch even cause workpiece distortion, 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, can effectively alleviate extrusion friction in the bending forming mould process and squeeze scratch and the distortion that causes to workpiece, and prolong the service life of bending forming mould.
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 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 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 pulley flanks is a 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 take place effectively.
As the further improved automobile suspension hook U-shaped bending forming mould of the utility model, 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 forming mould provided by the utility model, 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 forming mould process and squeeze scratch and the distortion that causes, and prolong the service life of bending forming mould to workpiece.

1 is upper bolster, and 2 is die shoe, and 3 is guide pillar and guide pin bushing, and 4 is crooked punch, and 5 is die, and 6 is pulley, and 7 is spring, and 8 are the discharging bolt.
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. 1-2, 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 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 in die 5 vestibules, moving 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 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, 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.
