DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following will be combined Figure 1~Figure 4 A television back panel stamping die according to an embodiment of the utility model is described in detail.

[0022] like Figure 1-4 As shown, a TV back panel stamping die comprises a lower base 1, an upper pressing plate 2 and a stamping handle 5 fixed on the top of the upper pressing plate, a guide shaft 3 is fixed on the lower base 1, a guide sleeve 4 is fixed on the bottom of the upper pressing plate 2, and the guide shaft 3 is slidably sleeved inside the guide sleeve 4. Specifically, a lower die assembly is fixed on the lower base 1, and the lower die assembly comprises a lower fixed plate 10 fixed on the lower base 1, a lower stamping die 17 is fixed at the center of the lower fixed plate 10, and the lower fixed plate 10 is connected to a clamping plate 9 with a central opening through a reset spring 18, and the lower stamping die 17 passes through the clamping plate 9; in addition, a guide rod 19 is fixed at the bottom of the clamping plate 9, and the guide rod 19 is slidably sleeved in the guide hole of the lower base 1. The clamping plate 9 can prevent the material plate from deforming during punching, and the reset spring 18 provides clamping force for the clamping plate 9 and resets it.

[0023] More specifically, an upper die assembly is fixed correspondingly below the upper pressing plate 2, and the upper die assembly includes an upper fixing plate 7 fixed to the bottom of the upper pressing plate 2 and a punching mechanism fixed to the bottom of the upper fixing plate 7. The punching mechanism specifically includes an upper punching plate 8 fixed to the bottom of the upper fixing plate 7, and an upper punching die 16 is slidably provided at the center of the upper punching plate 8. Figure 1 As shown, an upper pad 6 is installed between the upper pressing plate 2 and the upper fixing plate 7 , and a lower pad 11 is provided between the lower base 1 and the lower fixing plate 10 .

[0024] The above mechanism can realize automatic blanking of the TV back panel 22 after stamping, and its working principle is:

[0025] When in use, the punching handle 5 drives the upper pressing plate 2 and the upper die assembly to press downward. After the upper punching plate 8 and the upper punching die 16 contact the material plate, the upper punching die 16 presses the material against the lower punching die 17 to perform punching and forming. At the same time, the upper punching plate 8 continues to move downward to punch the periphery of the material plate and complete the punching process of the TV back plate 22. The excess material plate is pressed against the clamping plate 9 to prevent the material plate from deforming during punching. After the punching is completed, the punching handle 5 drives the upper pressing plate 2 and the upper die assembly to rise. Under the action of gravity, the upper punching die 16 moves downward relative to the upper punching plate 8 to eject the processed TV back plate 22 and realize automatic blanking.

[0026] More specifically, a connecting rod 15 is fixed on the upper stamping die 16, a limiting plate 14 is fixed on the top of the connecting rod 15, an auxiliary rod 13 is fixed on the limiting plate 14, the connecting rod 15 passes through the upper fixed plate 7, the auxiliary rod 13 passes through the stamping handle 5, and a cavity is provided at the center bottom of the upper pressing plate 2, and the limiting plate 14 is located in the cavity.

[0027] The function of the above mechanism is that when material jamming occurs, the auxiliary rod 13 can be knocked downward, thereby driving the upper punching plate 8 to move downward and ejecting the processed TV back panel 22.

[0028] On the basis of the above structure, in order to further realize the punching function, a number of punches 20 are fixed on the upper fixed plate 7, and the several punches 20 all penetrate the upper stamping die 16, and blanking holes 21 are provided on the lower stamping die 17 corresponding to the positions of the several punches 20; the diameter of the blanking hole 21 increases from top to bottom to prevent waste from clogging the blanking hole; in addition, blanking through holes are provided at corresponding positions on the lower pad 11 and the lower base 1, and a waste box 12 is also provided at the bottom of the lower base 1.

[0029] The punching principle is: during punching, the upper fixed plate 7 drives a plurality of punches 20 to move downward to punch holes in the material plate, and the waste material falls into the material drop hole 21, and then falls into the waste box 12 through the material drop hole for collection. Among them, the diameter of the material drop hole 21 increases from top to bottom, which can prevent the waste material from clogging the material drop hole.

[0030] The working principle of the TV back panel stamping die of this application is:

[0031] When in use, the punching handle 5 drives the upper pressing plate 2 and the upper die assembly to press downward. After the upper punching plate 8 and the upper punching die 16 contact the material plate, the upper punching die 16 presses the material against the lower punching die 17 to perform punching molding. At the same time, the upper punching plate 8 continues to move downward to achieve punching around the material plate and complete the punching process of the TV back panel 22. The excess material plate is pressed against the clamping plate 9 to prevent the material plate from deforming during punching. After the punching is completed, the punching handle 5 drives the upper pressing plate 2 and the upper die assembly to rise. Under the action of gravity, the upper punching die 16 moves downward relative to the upper punching plate 8 to eject the processed TV back panel 22 and realize automatic blanking. When the material is stuck, the auxiliary rod 13 can be knocked downward to drive the upper punching plate 8 to move downward and eject the processed TV back panel 22.

[0032] At the same time, the upper fixed plate 7 drives a plurality of punches 20 to move downward to punch holes in the material plate, and the waste material falls into the material drop hole 21, and falls into the waste box 12 through the material drop through hole for collection. Among them, the diameter of the material drop hole 21 increases from top to bottom, which can prevent material clogging.

[0033] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
