Description

Technical Field

[0001] The utility model relates to the technical field of stamping die production, in particular to a closed punching device for a display back panel stamping die. Background Art

[0002] People often come into contact with displays in daily use, such as TV displays and computer screens. During the display production process, the display module will be installed between the display casing and the back panel. Since some holes for wiring need to be opened on the display back panel, a stamping die is required to stamp the back panel raw material. Different display back panel stamping dies are required according to the form of the display. In order to realize the production of holes on the display back panel, the machine tool is required to open some closed holes in the display back panel stamping die.

[0003] When the existing machine tool opens and closes the hole in the display back panel stamping die, since the closed hole does not penetrate the die, some iron filings or a large amount of coolant used to cool the drill bit will remain inside the stamping die when the machine tool is drilling. Therefore, the workers need to clean the die later, which is cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a closed punching device for a stamping die of a display back panel comprises a stamping machine 1, a drilling platform 2 is installed at the drilling position of the stamping machine 1, a fixing frame 3 is fixedly installed at the bottom end of the drilling platform 2 near the drill bit, a lifting hole 4 is provided inside the fixing frame 3, a lifting block 5 is slidably and lifted inside the lifting hole 4, a rotating rod 6 is rotatably installed in the middle of the lifting block 5 through a bearing, a rotating hole 7 is provided at the bottom end of the fixing frame 3, the rotating hole 7 is connected with the lifting hole 4, the rotating hole 7 and the rotating rod 6 are mechanically sealed, an air hole 8 is provided at the central axis of the rotating rod 6, a spray hole 9 is provided at the bottom end of the rotating rod 6 in a ring array with the central axis of the rotating rod 6 as the axis, the spray hole 9 is connected with the air hole 8, a high-pressure air pipe 10 is installed on one side of the top end of the fixing frame 3, and the high-pressure air pipe 10 is connected to the inside of the lifting hole 4.

[0023] like Figures 1 to 5 As shown, a motor 11 is fixedly installed on one side of the fixed frame 3, and a gear 12 is fixedly installed on the output end of the motor 11 through the fixed frame 3. The output end of the motor 11 is arranged in a rotational seal with the fixed frame 3, and a rack 13 is fixedly installed on one side of the lifting block 5, and the gear 12 is meshed and connected with the rack 13.

[0024] The lifting block 5 can be controlled to slide and rise and fall inside the lifting hole 4 .

[0025] like Figures 1 to 5 As shown, a thread block 14 is integrally fixedly installed on the outer side of the rotating rod 6 , and a thread groove 15 is provided inside the bottom end of the fixing frame 3 at a position corresponding to the thread block 14 , and the thread groove 15 is threadedly connected to the thread block 14 .

[0026] When the lifting block 5 is driven to rise by the motor 11, the threaded block 14 on the rotating rod 6 is threadedly connected with the threaded groove 15 inside the bottom end of the fixed frame 3, which will synchronously drive the two pushing blocks 16 at the bottom of the rotating rod 6 to rotate, and some residual iron filings inside the closed hole are pushed, so that the iron filings and water inside the entire closed hole can be cleaned.

[0027] like Figures 1 to 5 As shown, the spray hole 9 is arranged to be inclined upward.

[0028] Some residual iron filings and water inside the closed hole can be pushed upward, so that the iron filings and water are completely blown out of the closed hole.

[0029] like Figures 1 to 5 As shown, a push block 16 is installed at the bottom of the rotating rod 6 through damping rotation, and the lower surface of the push block 16 when horizontal is arranged in the same plane as the bottom end of the rotating rod 6.

[0030] After the pusher block 16 moves to the bottom of the closed hole, it is squeezed by the bottom of the closed hole and then rotates, so that the pusher block 16 can be completely attached to the bottom of the closed hole to prevent residual iron filings from remaining at the bottom of the closed hole.

[0031] like Figures 1 to 5 As shown, a limiting protrusion 17 for limiting the rotation angle of the pushing block 16 is integrally fixedly mounted on the bottom end of the rotating rod 6 .

[0032] The push block 16 can be prevented from excessively rotating, thereby preventing the push block 16 from moving to the bottom of the closed hole and being unable to rotate.

[0033] like Figures 1 to 5 As shown, a limiting ring 18 for resetting the rotation angle of the pusher block 16 is fixedly installed at the bottom of the fixing frame 3 corresponding to the position of the pusher block 16 .

[0034] When the pusher block 16 moves to the bottom of the fixed frame 3 as the rotating rod 6 rises, the pusher block 16 can be reset at an inclined angle.

[0035] The utility model provides a display back panel punching die closing punching device, the specific working principle is as follows:

[0036] When the device is in use, the display back panel stamping die to be processed is placed on the stamping machine 1. After the position of the stamping die is detected, the punching machine 1 controls the drilling platform 2 to operate, and a closed hole is punched in the stamping die. After the punching is completed, the punching machine 1 controls the drilling platform 2 to move, and the rotating rod 6 on the fixed frame 3 is aligned with the closed hole. The motor 11 drives the gear 12 to rotate, and the gear 12 is engaged with the rack 13 to drive the lifting block 5 to slide and descend inside the lifting hole 4. At the same time, the rotating rod 6 will also be driven to descend and the bottom end of the rotating rod 6 will be extended into the bottom of the closed hole. When the bottom end of the rotating rod 6 extends into the bottom of the closed hole, the pusher block 16 will be squeezed by the bottom of the closed hole and then rotate. When 6 is fully unfolded and contacts the plane at the bottom of the closed hole, air is filled into the high-pressure air pipe 10 through the air pressure device, and the air hole 8 at the bottom of the rotating rod 6 will blow air to the bottom of the closed hole to blow out the iron filings and water at the bottom of the closed hole. At this time, the high-pressure gas ejected through the air hole 8 and the spray hole 9 will blow out the iron filings and water at the bottom of the entire closed hole, and then the lifting block 5 is reversely controlled to rise by the motor 11. The threaded block 14 on the rotating rod 6 is threadedly connected with the threaded groove 15 inside the bottom end of the fixing frame 3 to synchronously drive the rotating rod 6 and the two pushing blocks 16 at the bottom of the rotating rod 6 to rotate, and some residual iron filings on the inner wall of the closed hole are pushed, so that the iron filings and water inside the entire closed hole can be cleaned.
