Description

Technical Field

[0001] This utility model relates to the field of television back panel manufacturing technology, specifically to a die for bending the edge of a television back panel. Background Technology

[0002] In the field of television back panels, back panel products typically employ an F-edge structure to support the weight of the television glass. Current technology often uses a die-bending mold to manufacture the F-edge structure. However, because the F-edge structure requires multiple bending processes, various die-bending molds are needed to complete its manufacturing, resulting in low production efficiency and high production costs.

[0003] Therefore, how to improve the production efficiency of F-side structures has become an urgent technical problem to be solved. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a die for bending the dead edge of a TV back panel, which can improve the production efficiency of the F-edge structure of the TV back panel.

[0005] The above-mentioned technical problem is solved by the following technical solution: a die for bending the sidewall of a TV back panel, used for bending the sidewall of a first back panel, the sidewall of the first back panel including a first flat plate and a second flat plate connected to each other, the first flat plate and the second flat plate being arranged at an included angle, the first flat plate having a first thickness, the second flat plate having a second thickness, the die comprising: A protrusion is used to horizontally place the first flat plate, so that the second flat plate is suspended downwards above the protrusion; The first punch module includes a bending punch and a first driving member that drives the bending punch to move up and down between a first position and a second position; when the bending punch is in the first position, the bending punch is located above the protrusion; when the bending punch is in the second position, the bending punch is located on the outward side of the protrusion, and the distance between the bending punch and the protrusion is equal to the first thickness. The second punch module includes a reverse flat punch and a second driving member that drives the reverse flat punch to move up and down between a third position and a fourth position; when the reverse flat punch is in the third position, the reverse flat punch is located below the protrusion and the two are spaced apart; when the reverse flat punch is in the fourth position, the reverse flat punch abuts against the bottom of the protrusion and the reverse flat punch is located on the inward side of the bending punch in the second position, and the distance between the reverse flat punch and the bending punch in the second position is equal to the sum of the first thickness and the second thickness.

[0006] The aforementioned edge-bending die, by simultaneously incorporating a protrusion, a first punch module, and a second punch module, allows the first flat plate of the first back plate to bend downwards when placed on the protrusion. This causes the first flat plate to bend downwards, aligning the second flat plate inwards. Then, the reverse-bending punch of the second punch module moves upwards, bringing the first and second flat plates into contact, thus completing the edge-bending of the back plate area. Therefore, this technical solution can complete the above processes simultaneously with a single die set, eliminating the need for workers to move the back plate, resulting in high production efficiency and lower costs.

[0007] Furthermore, the sidewall of the protrusion has a first plane, and the sidewall of the bending punch has a second plane parallel to the first plane. When the bending punch is in the second position, the second plane is located on the side of the first plane facing outward, and the distance between the first plane and the second plane is equal to the first thickness.

[0008] Furthermore, the first plane and the second plane are inclined planes.

[0009] Furthermore, the sidewall of the reverse flat punch has a third plane parallel to the first plane. When the reverse flat punch is in the fourth position, the distance between the third plane and the second plane of the bending punch in the second position is equal to the sum of the first thickness and the second thickness.

[0010] Furthermore, the first plane, the second plane, and the third plane are inclined planes.

[0011] Furthermore, the bottom of the protrusion is a concave arc surface, and the top of the counter-striking flat punch is a convex arc surface corresponding to the concave arc surface.

[0012] Furthermore, the mold includes a lower mold base and a stripping module, the protrusion being a partial structure of the lower mold base and located on the side of the lower mold base; the stripping module includes an upper stripping plate and a first driving member that drives the upper stripping plate to move up and down between a fifth position and a sixth position; when the upper stripping plate is in the fifth position, the upper stripping plate is located above the lower mold base, and the distance between the upper stripping plate and the lower mold base is greater than the first thickness; when the upper stripping plate is in the sixth position, the upper stripping plate is located above the lower mold base, and the distance between the upper stripping plate and the lower mold base is equal to the first thickness.

[0013] Furthermore, the lower mold base is provided with protrusions on both the left and right sides.

[0014] Furthermore, the bending punch includes a left bending punch and a right bending punch. The left bending punch engages with a protrusion located on the left side of the lower die base, and the right bending punch engages with a protrusion located on the right side of the lower die base.

[0015] Furthermore, the reverse flat punch includes a left reverse flat punch and a right reverse flat punch. The left reverse flat punch engages with a protrusion located on the left side of the lower die holder, and the right reverse flat punch engages with a protrusion located on the right side of the lower die holder.

[0023] In one embodiment, such as Figure 1-2 As shown, a first back panel is provided. The sidewalls of the first back panel include a first planar plate 101 and a second planar plate 102 connected to each other. The first planar plate 101 and the second planar plate 102 are arranged at an included angle. The first planar plate 101 has a first thickness, and the second planar plate 102 has a second thickness. Figure 3-6 As shown, a die for bending the dead edge of a television back panel is provided, used for bending the aforementioned... Figure 1-2 The sidewall of the first back panel is subjected to a dead-edge bending process, and the mold includes: The protrusion 1 is used to horizontally place the first flat plate 101 so that the second flat plate 102 is suspended downwards above the protrusion 1; The first punch module includes a bending punch 2 and a first driving member that drives the bending punch 2 to move up and down between a first position and a second position; when the bending punch 2 is in the first position, the bending punch 2 is located above the protrusion 1; when the bending punch 2 is in the second position, the bending punch 2 is located on the outward side of the protrusion 1, and the distance between the bending punch 2 and the protrusion 1 is equal to the first thickness; The second punch module includes a reverse flat punch 3 and a second driving member that drives the reverse flat punch 3 to move up and down between a third position and a fourth position.
