Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1 to 3, an upper die roller positioning device includes an upper die 1 and a lower die 2, where the upper die 1 includes an upper die base 11, an upper die base plate 12, an upper fixing plate 13, a plurality of punching heads 14 and a guide post 15, the lower die 2 includes a lower die base 21, a die mounting block 22 disposed on the lower die base 21, and a die 23 mounted on the die mounting block 22 and configured by a copying stamping part, a positioning mechanism 3 is further disposed on the upper fixing plate 13 to limit the stamping part to be attached to the die 23, and the positioning mechanism 3 includes a roller mounting base 31 disposed on the upper fixing plate 13 and a roller 33 mounted on the roller mounting base 31 through a bearing 32, and is bilaterally symmetrical to the roller mounting base 31.

The die 23 is fixedly installed at the front end of the die installation block 22 through screws, the die 23 is not in contact with the lower die holder 21, a gap is reserved, an open slot is formed in the bottom of the die 23 for the purpose of being matched with installation limit of the stamping part 5, and stamping waste materials after stamping of the upper die 1 can fall into the blanking groove 25 from the open slot. The appearance of die with stamping workpiece 5's imitative shape sets up, because stamping workpiece 5's large tracts of land is curved groove face, in order to live stamping workpiece 5 and the inseparable laminating of die 23, guarantees the precision that stamping workpiece 5 placed, consequently need cooperate positioning mechanism 3 to compress tightly the location.

When the upper die moves downwards, the roller 33 of the positioning mechanism 3 can be attached to and roll downwards along the stamping part 5, if the stamping part 5 is not attached in place, the stamping part 5 and the female die can be pressed and attached due to the pressing of the roller 33, so that accurate positioning is realized, and the stamping precision is ensured.

A guide assembly 4 is arranged between the upper die 1 and the lower die 2, and the guide assembly 4 comprises a guide column 41 and a guide sleeve 42. The guide post and the guide sleeve 42 are matched with the upper die 1 and the lower die 2 to have a guide function in the process of die opening and die closing, so that the precision of the vertical movement of the upper die and the lower die is improved.

The female die 23 is provided with a plurality of punching grooves 24 which are matched with the punching head 13 for punching. In order to match with the punching head 13 for punching, a punching groove 24 matched with punching is formed in the female die for punching, and a punching space is reserved.

In order to cooperate with waste recovery, a charging chute 25 is arranged on the lower die base 21, and the charging chute 25 is arranged below the female die 23.

The material of gyro wheel 33 has certain elasticity, and specific nylon material or rubber material do not cause the damage to stamping workpiece 5, protection stamping workpiece 5. And the contact surface of the roller and the stamping part is few, so that the friction between the roller and the stamping part is reduced, and the appearance of the stamping part is ensured.

This embodiment, the manual work will wait that the die 22 of stamping workpiece 5 laminating profile modeling sets up, with the die 22's of the concave surface of stamping workpiece 5 and the profile surface laminating setting, start the punch press, the drive goes up the mould and pushes down, push down in-process positioning mechanism 3 and contact with stamping workpiece 5 earlier, gyro wheel 33 of both sides pushes down stamping workpiece 5 and rolls and moves down, make stamping workpiece 5 and die press and cover the laminating, and inject stamping workpiece 5's position, punch head 14 moves down simultaneously, die-cut hole groove, unnecessary cooperation is punched out from punching hole groove 24 and is dropped to blanking groove 25 in, after punching press, go up the mould and reset, work more than the repetition.

The utility model has the advantages that the positioning mechanism is arranged on the upper die and moves along with the movement of the upper die, so that the blockage and the obstruction to the feeding and discharging can be avoided during manual operation, the operation is more convenient, and the table top is clearer; and a roller type positioning mechanism is adopted, the roller presses the stamping part to roll downwards, so that the stamping part and the female die are pressed and attached, the stamping precision is ensured, the contact surface between the roller and the stamping part is less, the friction between the roller and the stamping part is reduced, and the appearance of the stamping part is ensured.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
