[0018] Example 1

[0019] like Figures 1 to 4 As shown, this utility model proposes a display screen back panel side punching device, including a base 1, a lower mold mounting base 4, and a side mold base 6. A back plate 101 is provided at the top of the base 1. A punching upper mold is detachably mounted on the back plate 101 via a punching hydraulic press. This is prior art, and its specific structure and principle are detailed in the patent with authorization announcement number CN217432767U, and will not be repeated here. Two sets of side pressure support plates 102 symmetrically arranged on the punching upper mold on the back plate 101 are each detachably mounted with a side pressure upper mold base 2 via a side pressure cylinder. A socket is provided at the top of the side pressure upper mold base 2, and the output end of the side pressure cylinder is detachably connected to the socket via bolts. A recess is provided on the side pressure upper mold base 2. Two sets of lower mold mounting bases 4 are provided, and the two sets of lower mold mounting bases... The base 4 is adjustable and slidably connected to the base 1. A forming lower mold base 5 is detachably installed between the tops of the two sets of lower mold mounting bases 4. The forming lower mold base 5 corresponds to the punching upper mold on the back plate 101. The punching upper mold and the side pressing upper mold base 2 are provided with different models. The punching upper mold is equipped with a matching forming lower mold base 5, which can process different models of display screen back plates. There are two sets of side mold bases 6. The two sets of side mold bases 6 are detachably connected to the corresponding lower mold mounting bases 4. The top of the side mold base 6 is provided with a protrusion 601. The protrusion 601 corresponds to the recess on the side pressing upper mold base 2. The protrusion 601 is connected to the top surface of the forming lower mold base 5. The protrusion 601 can be pre-processed into multiple different models according to the bending model of the side of the display screen back plate.

[0020] Furthermore, an adjustment mechanism is provided at the top of the base 1. The two sets of lower mold mounting seats 4 are adjusted to move closer or further apart from each other along the base 1 through the adjustment mechanism. The adjustment mechanism includes a mounting groove 3 and a slide 302. The mounting groove 3 is set on the base 1, and a bidirectional lead screw 301 is rotatably connected inside the mounting groove 3. Two sets of slides 302 are provided. The two sets of slides 302 are symmetrically slidably connected to the inner wall of the mounting groove 3, and both sets of slides 302 are threadedly connected to the bidirectional lead screw 301. The bottom ends of the two sets of lower mold mounting seats 4 are respectively connected to the top ends of the corresponding slides 302.

[0021] Furthermore, the upper mounting part 401 is provided at the top of the lower mold mounting base 4, and the upper mounting part 401 is provided with a threaded groove. The forming lower mold base 5 is detachably connected to the upper mounting part 401 at the top of the two sets of lower mold mounting bases 4 by bolts.

[0022] Furthermore, the lower mold mounting base 4 has a side mounting part 403 on its side wall. The side mounting part 403 abuts against the side wall of the side mold base 6. The side wall and bottom of the side mounting part 403 are provided with guide grooves 404. The side mold base 6 is connected to the lower mold mounting base 4 through two sets of guide grooves 404.

[0023] Furthermore, a connecting seat 602 is installed at the bottom of the side mold base 6. A guide seat 603 is installed on one side wall and the bottom of the connecting seat 602. The cross-section of the guide seat 603 and the guide groove 404 is T-shaped. The guide seat 603 and the guide groove 404 are slidably connected. A limiting part 402 is also provided at the rear end of the lower mold mounting base 4. The top height of the limiting part 402 is higher than the top height of the forming lower mold base 5. The rear ends of the side mold base 6, the connecting seat 602 and the guide seat 603 abut against the corresponding limiting part 402, which makes it easy for the side mold base 6 to quickly align with the lower mold mounting base 4. The limiting part 402 also facilitates abutment with the rear end of the display screen back plate, thereby quickly installing the display screen back plate on the forming lower mold base 5 at a suitable position.

[0024] In this embodiment, a suitable punching upper die is installed on a punching hydraulic press on a back plate 101, and a suitable side pressure upper die seat 2 is installed on a side pressure cylinder on a side pressure support plate 102. Rotating the handle on the bidirectional lead screw 301 causes the two sets of slide blocks 302 to slide away or towards each other along the mounting groove 3, thereby causing the two sets of lower die mounting seats 4 to move away or towards each other, thus installing the forming lower die seat 5 corresponding to the punching upper die. The forming lower die seat 5 is connected to the threaded groove between the mounting portion 401 at the top of the two sets of lower die mounting seats 4 by bolts, thereby installing the forming lower die seat 5 between the two sets of upper mounting portions 401. A suitable side die seat 6 is selected. It should be noted that the protrusion 60 on the side die seat 6... 1. It needs to match the recessed part on the side pressure upper mold base 2. Align the two sets of guide seats 603 on the side mold base 6 with the two sets of guide grooves 404 on the side mounting part 403 and slide them in until the rear end of the side mold base 6, the connecting seat 602 and the guide seat 603 abut against the limiting part 402. Then the side mold base 6 can be quickly installed on the lower mold mounting base 4. At this time, the display screen back plate can be placed at a suitable position on the top of the forming lower mold base 5 and the rear end of the display screen back plate abuts against the two sets of limiting parts 402. The punching hydraulic press can be started by the controller to drive the punching upper mold to punch the display screen back plate first. Then the side pressure cylinder drives the side pressure upper mold base 2 to move towards the protrusion 601 to side pressure form the side of the display screen back plate.

[0025] Example 2

[0026] like Figures 2 to 4 As shown, the display screen back panel side punching device proposed in this utility model, compared with the first embodiment, also includes a protective component. The protective component consists of a sliding sleeve 405 installed on the side wall of one set of lower mold mounting bases 4 and a sliding plate 406 installed on the side wall of another set of lower mold mounting bases 4. The other end of the sliding plate 406 is slidably connected to the inner wall of the other end of the sliding sleeve 405. The sliding sleeve 405 and the sliding plate 406 are both slidably connected to the top surface of the base 1, and the sliding sleeve 405 and the sliding plate 406 both cover the mounting groove 3.

[0027] In this embodiment, when the two sets of lower mold mounting seats 4 move closer or further apart under the adjustment mechanism, the sliding sleeve 405 and the sliding plate 406 will slide closer or further apart to each other, thus always blocking the mounting groove 3 below the forming lower mold seat 5. When the punching upper mold on the back plate 101 moves down to punch the display screen back plate on the forming lower mold seat 5, the waste generated falls into the space between the two sets of lower mold mounting seats 4 and the base 1. The protective component can prevent the waste from falling into the mounting groove 3 and interfering with the adjustment mechanism.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
