Detailed implementation mode

[0029] The present invention will be further described in detail below with reference to the attached drawings.

[0030] As Figures 1-9 shown, the present invention discloses an upward flanging die for automotive part 2, including a lower die holder 1, an upper die holder matching with the lower die holder 1, and a driving block 11 slidably connected to the lower die holder 1, characterized in that

[0031] One side of the driving block 11 is provided with a lifting module 12 for flanging, and the other side is provided with a pressing module 13 for moving the lifting module 12 upward;

[0032] When the pressing module 13 moves downward, the lifting module 12 is moved upward through the driving block 11 to perform stamping flanging on the automotive part 2, and then the lifting module 12 is reset through the reset assembly 14; wherein,

[0033] The lifting module 12 includes a plurality of flanging inserts 121, and the flanging inserts 121 are provided with adjustable protruding parts 1211 matching with the automotive part 2, and the protruding parts 1211 process the automotive part 2.

[0034] The lifting module 12 makes a reciprocating up and down movement under the action of the pressing module 13 and the driving block 11. During the upward movement of the lifting module 12, the adjustable protruding parts 1211 on the plurality of flanging inserts 121 simultaneously perform flanging stamping on the automotive part 2, improving the stamping efficiency. In addition, the structure of this die is simple, and the position of the protruding part 1211 is adjustable, which can be applied to the flanging stamping of automotive parts 2 with relatively small size differences, reducing the die development cost.

[0035] In some embodiments of the present utility model, the protruding portion 1211 is slidably connected to the flanging insert 121 through a bolt 1212. The end of the bolt 1212 is a spherical structure and is rotatably connected to the protruding portion 1211. The protruding portion 1211 adjusts the relative position between the protruding portion 1211 and the flanging insert 121 through a U-shaped groove. In the normal stamping state, the side wall of the protruding portion 1211 and the side wall of the flanging insert 121 are in the same plane. The design of the spherical structure can finely adjust the angle between the protruding portion 1211 and the flanging insert 121, so that there is an angle between the side wall of the protruding portion 1211 and the side wall of the flipping insert, realizing flanging of different styles of the automotive part 2.

[0036] In some embodiments of the present utility model, the driving block 11 has a first inclined surface 111 slidably connected to the pressing module 13 and a second inclined surface 112 slidably connected to the jacking module 12. Driving guide plates 113 are connected between the pressing module 13 and the first inclined surface 111, and between the jacking module 12 and the second inclined surface 112. The settings of the first inclined surface 111 and the second inclined surface 112 facilitate the movement of the pressing module 13 and the jacking module 12. Moving one of the components can realize the movement of the other two components. The structure is simple and the linkage is strong. In addition, the setting of the driving guide plates 113 reduces the friction force between the contact surfaces, makes the movement smoother, and reduces the occurrence of jamming phenomena.

[0037] In addition, side guide plates 16 are installed on the side walls of the jacking module 12 and the pressing module 13. The side guide plates 16 have the same function as the driving guide plates 113 and are used to reduce the friction force between the jacking module 12, the pressing module 13 and the lower die holder 1.

[0038] In some embodiments of the present utility model, the reset assembly 14 is arranged on one side of the driving block 11 and includes a nitrogen spring 141 and an installation groove 142 for placing the nitrogen spring 141. When the pressing module 13 stops applying pressure to the driving block 11, the nitrogen spring 141 resets the driving block 11 to the left.

[0039] In some embodiments of the present utility model, the upward flanging die for the automotive part 2 further includes a limiting block 15 for restricting the upward movement of the jacking module 12 and the pressing module 13. When the die is in the working state, the left and right sides of the limiting block 15 are respectively in contact with the pressing module 13 and the jacking module 12, avoiding interference between the two and affecting the stamping quality. Among them, the limiting block 15 is a rectangular block and is fixed between the lower die holder 1 and the driving block 11.

[0040] In some embodiments of the present utility model, first clamping blocks 114 for restricting the upward movement of the downward pressing module 13 are installed on both sides of the lower die carrier 1, and first limiting portions 131 abutting against the first clamping blocks 114 are provided on both sides of the downward pressing module 13. During the upward movement of the downward pressing module 13, in order to prevent the downward pressing module 13 from detaching from the lower die carrier 1, the first clamping blocks 114 are provided on both sides of the lower die carrier 1, and the first limiting portions 131 matching the first clamping blocks 114 are provided on the downward pressing module 13, thereby improving the stability of the flanging die during operation.

[0041] In some embodiments of the present utility model, second clamping blocks 115 for restricting the up-and-down movement of the driving block 11 are installed inside the lower die carrier 1, and second limiting portions 116 abutting against the second clamping blocks 115 are provided on one side of the driving block 11. During the reciprocating translation of the driving block 11, when the frictional force is large, the driving block 11 may be tilted. Therefore, the second clamping blocks 115 are provided inside the lower die carrier 1 to restrict the upper and lower parts of the driving block 11, enabling the driving block 11 to only move horizontally, thereby improving the stability of the driving block 11 during operation.

[0042] In some embodiments of the present utility model, a stamping platform 17 is further provided on the upper surface of the lower die carrier 1, and the automotive part 2 is stamped and formed on the stamping platform 17.

[0043] During the working process of the die, the upper die carrier (not shown) moves downward and gradually contacts the lower die carrier 1, applying pressure to the downward pressing module 13 to make the downward pressing module 13 move downward. Since there is a first inclined surface 111 between the downward pressing module 13 and the driving block 11, under the action of the first inclined surface 111, the driving block 11 moves to the right against the elastic force of the nitrogen spring 141. Also, since there is a second inclined surface 112 between the driving block 11 and the jacking module 12, under the action of the second inclined surface 112, the jacking module 12 moves upward, and at the same time, the flanging insert 121 fixed above the jacking module 12 and the protruding portion 1211 move upward together to perform flanging stamping on the automotive part 2; when the stamping is completed, the upper die carrier moves upward to reset and stops applying pressure to the downward pressing module 13. The nitrogen spring 141 in the reset assembly 14 makes the driving block 11 move to the left. At this time, the jacking module 12 moves downward under the influence of gravity, and the protruding portion 1211 separates from the automotive part 2, completing one action cycle of the flanging stamping of the automotive part 2.

[0044] For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
