DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] As shown in Figures 1 to 4 Fig. 1 is a television stamping backboard die, including processing table 1, stamping mechanism 2 and deviation rectifying mechanism 3, stamping mechanism 2 includes support frame 21, hydraulic cylinder 22, lower pressing die 23 and upper pressing die 24, the bottom of support frame 21 is fixedly connected with processing table 1, hydraulic cylinder 22 is fixedly connected with the top of support frame 21, lower pressing die 23 is fixedly connected with the output end of hydraulic cylinder 22, upper pressing die 24 is fixedly arranged on the top of processing table 1 and is located below lower pressing die 23, deviation rectifying mechanism 3 includes first sliding table 31, second sliding table 32 and deviation rectifying pressing plate 33, the top of processing table 1 is provided with first sliding groove 34 and second sliding groove 35 which are horizontal and perpendicular to each other, upper pressing die 24 is located at the intersection of first sliding groove 34 and second sliding groove 35, two symmetrical first sliding tables 31 are slidably arranged in first sliding groove 34, two symmetrical second sliding tables 32 are slidably arranged in second sliding groove 35, deviation rectifying pressing plate 33 is fixedly arranged on the side of first sliding table 31 and second sliding table 32, processing table 1 is provided with adjusting assembly 4 for adjusting the positions of first sliding table 31 and second sliding table 32 in first sliding groove 34 and second sliding groove 35 respectively.

[0022] Specifically, the backboard to be stamped is placed on processing table 1, and the initial position is as close as possible to the position directly below upper pressing die 24. At this time, deviation rectifying pressing plate 33 on first sliding table 31 and second sliding table 32 is in a non-contact state and will not generate force on the backboard. Then, hydraulic cylinder 22 is started, and the output end of hydraulic cylinder 22 drives lower pressing die 23 to move downward, preparing to cooperate with upper pressing die 24 to stamp.

[0023] Before stamping, the positions of the first slide 31 and the second slide 32 in the first slide groove 34 and the second slide groove 35 are adjusted by the adjusting assembly 4. The correction pressure plate 33 moves with the movement of the slide, gradually approaches the back plate and applies slight pressure, so that the back plate is finely adjusted to the accurate position in the horizontal direction. This process ensures the alignment accuracy of the back plate with the upper die 24 and the lower die 23. When the back plate is accurately positioned, the hydraulic cylinder 22 continues to drive the lower die 23 downward to complete the stamping action together with the upper die 24.

[0024] After stamping is completed, the hydraulic cylinder 22 drives the lower die 23 to rise and reset, and at the same time, the adjusting assembly 4 resets the first slide 31 and the second slide 32, and the correction pressure plate 33 is separated from the back plate. At this time, the stamped back plate can be taken out for the next operation.

[0025] By means of the correction mechanism 3, the back plate can be finely adjusted before stamping to ensure accurate alignment with the upper die 24 and the lower die 23, thereby avoiding the problem of inaccurate stamping due to positioning deviation. Accurate positioning ensures the stability of the back plate during stamping, reduces deformation and error during stamping, and improves the overall quality of the stamped part. At the same time, the correction mechanism 3 can quickly and accurately adjust the position of the back plate, reducing repeated adjustment and stamping failure caused by inaccurate positioning, thereby improving production efficiency. In addition, the position of the correction pressure plate 33 can be flexibly adjusted by the adjusting assembly 4, which is suitable for back plates of different sizes and shapes, enhancing the versatility and adaptability of the mold.

[0026] Reference Figure 2 and Figure 3 As shown in FIGS. 1-3, in some embodiments, the adjusting assembly 4 includes a lead screw 41, a driven bevel gear 42, a driving bevel gear 43, a rotating shaft 44, and a rotary motor 45. The lead screw 41 is rotatably arranged in the first slide groove 34 and the second slide groove 35, and the first slide 31 and the second slide 32 are provided with a rotating hole matched with the corresponding lead screw 41. One end of each lead screw 41 is fixedly provided with a driven bevel gear 42, the rotating shaft 44 is rotatably connected with the machining table 1 in a vertical state, the driving bevel gear 43 is coaxially fixedly connected with the rotating shaft 44 and engaged with all the driven bevel gears 42. The rotary motor 45 is fixedly connected with the machining table 1, and the output end of the rotary motor 45 is coaxially fixedly connected with the rotating shaft 44.

[0027] In the initial state, the first sliding table 31 and the second sliding table 32 are respectively matched with the lead screw 41 in the first sliding groove 34 and the second sliding groove 35 through the rotation holes thereon, but are not subjected to driving force, thus being in a static state. When it is necessary to adjust the positions of the first sliding table 31 and the second sliding table 32, the rotary motor 45 is started. The output end of the rotary motor 45 drives the rotation shaft 44 to rotate, and since the driving bevel gear 43 is coaxially fixedly connected with the rotation shaft 44, the driving bevel gear 43 also rotates synchronously. The driving bevel gear 43 is meshed with all the driven bevel gears 42, thus when the driving bevel gear 43 rotates, it drives all the driven bevel gears 42 and the lead screws 41 fixedly connected therewith to rotate synchronously. With the rotation of the lead screws 41, the first sliding table 31 and the second sliding table 32 are matched with the lead screws 41 through the rotation holes thereon and the threads therebetween, thus moving along the directions of the sliding grooves under the guidance of the lead screws 41. Due to the transmission characteristics of the lead screws 41, the movement is accurate and stable.

[0028] Through the continuous rotation of the rotary motor 45 and the transmission of the bevel gears and the lead screws 41, the positions of the first sliding table 31 and the second sliding table 32 in the first sliding groove 34 and the second sliding groove 35 can be accurately adjusted, thus realizing the accurate rectification of the back plate.

[0029] Reference Figure 1 As shown in some specific embodiments, the rectification pressing plate 33 is made of rubber material. The rubber material has good elasticity and flexibility, which enables the rectification pressing plate 33 to produce moderate deformation when in contact with the back plate, so as to better adapt to the surface shape and slight unevenness of the back plate. Such adaptability helps to reduce the impact and noise caused by hard contact, and protects the back plate from damage. Such protection helps to prolong the service life of the back plate and reduce the scrap rate caused by damage.

[0030] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
