Description

Technical Field

[0001] The utility model relates to the field of display back panels, in particular to an integrated stamping die structure for special-shaped holes of display back panels. Background Art

[0002] In the processing of display back panels, one of the processing difficulties is punching. When the punched holes are irregular parts, the difficulty of forming increases accordingly, especially for special-shaped holes in a bending structure. The existing processing method generally uses two steps for forming, but there are multiple holes. Therefore, with the increase of two processing steps, the corresponding processing efficiency and the processing of defective products also increase (which involves problems such as repositioning and displacement). It includes two steps of forming and puncturing. After the predetermined recessed slots are stamped, the next process is to perform forming and punching. Utility Model Content

[0003] The main purpose of the utility model is to provide an integrated stamping die structure for displaying special-shaped holes on a back plate, aiming to realize integrated forming of the special-shaped holes and cut and form predetermined clamping holes.

[0004] To achieve the above-mentioned purpose, the utility model proposes an integrated stamping die structure for displaying a back plate irregular hole, comprising a first stamping head and a matching second stamping head, wherein the first stamping head and the second stamping head are respectively slidably mounted on an upper die;

[0005] The first punch head and the second punch head are respectively provided with a first fitting surface and a second fitting surface, and the first fitting surface and the second fitting surface are in contact with each other;

[0006] The first punching head is an inclined surface, the end of the inclined surface is provided with a blade portion, and the middle of the inclined surface is provided with a forming portion;

[0007] The end of the second punching head that is in contact with the first punching head is provided with a puncturing blade.

[0008] In the actual processing of the technical solution of the utility model, the metal display back panel is positioned under the fitting of the upper die and the lower die, and then the first punch head slides downward and fits with the back panel to preliminarily form a predetermined groove, and then the piercing blade of the second punch head directly pierces the end of the groove, and then the first punch head continues to descend and punches out the special-shaped hole, and then forms a special-shaped hole that matches the shape of the first punch head, thereby realizing one-time forming at the same work station, effectively saving processing steps, and at the same time improving processing stability.

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0017] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0018] like Figures 1 to 4As shown, an integrated stamping die structure for displaying a back plate irregular hole comprises a first stamping head 1 and a matching second stamping head 2, wherein the first stamping head 1 and the second stamping head 2 are respectively slidably mounted on an upper die;

[0019] The first punch head 1 and the second punch head 2 are respectively provided with a first mating surface 31 and a second mating surface 32, and the first mating surface 31 and the second mating surface are in contact with each other;

[0020] The first punch head 1 is an inclined surface 11, the end of the inclined surface 11 is provided with a blade portion, and the middle of the inclined surface 11 is provided with a forming portion 13;

[0021] The end of the second punch head 2 that is in contact with the first punch head 1 is provided with a piercing blade 21 .

[0022] In actual processing, the metal display back panel 200 is positioned under the fitting of the upper mold and the lower mold, and then the first punch head 1 slides downward and fits with the back panel to preliminarily form a predetermined groove, and then the piercing blade 21 of the second punch head directly pierces the end of the groove, and then the first punch head continues to move downward and punches out the special-shaped hole, and then forms the special-shaped hole 100 that matches the shape of the first punch head, thereby achieving one-time forming at the same work station, effectively saving processing steps and improving processing stability.

[0023] In the embodiment of the utility model, the first mating surface and the second mating surface are both 45-degree inclined surfaces 11, so that the puncturing and forming are synchronized, but the two do not interfere with each other.
