Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a forming die for the triangular plate of a civil air defense door leaf. Background Technique

[0002] A civil air defense door is the door at the entrance of a people's air defense project. The classification of civil air defense doors is relatively distinct, including various civil air defense equipment such as ordinary single and double leaf airtight and blast-proof doors and airtight doors, and single and double leaf airtight and blast-proof doors with movable thresholds. Civil air defense doors are usually made of welded steel plates and filled with a large amount of filling materials, making them relatively heavy. Civil air defense doors are mainly hinged to the door frame in the civil air defense project through triangular plates. Triangular plates are usually made of steel plates. When manufacturing the triangular plates of the door leaf, a punching machine and a stamping die are required.

[0003] Before stamping the triangular plate of the civil air defense door leaf, first place the steel plate on the lower die of the punching machine, and then start the stamping component to drive the upper die to stamp the steel plate. Since the upper pressing die is generally fixedly installed on the stamping component, and the stamping upper die bears a large impact pressure during work and needs to be repaired and maintained frequently. When the upper die is damaged, it is inconvenient to quickly disassemble it, and different upper dies cannot be replaced, so that it can only adapt to one shape of the triangular plate of the door leaf, thus reducing the practicability of the device. Therefore, we propose a forming die for the triangular plate of a civil air defense door leaf. Content of the Utility Model

[0024] Specifically, starting the driving mechanism 4 can drive the locking mechanism 3 to release the clamping and locking of the upper die 5. At this time, the upper die 5 will fall naturally to complete the disassembly. Reversing the driving mechanism 4 when the upper die 5 is reinstalled at the bottom of the mounting plate 2 can drive the locking mechanism 3 to lock and clamp the upper die 5 again, so as to complete the installation of the upper die 5. When the stamping assembly drives the upper die 5 to descend through the mounting plate 2 to stamp the steel plate, the mounting plate 2 drives the four pressing mechanisms 6 to squeeze the four buffer mechanisms 7 respectively, so as to buffer the upper die 5 during stamping, thereby reducing the damage to the upper die 5.

[0025] Embodiment 2:

[0026] Please refer to Figures 2 to 3, in the embodiment of the present utility model, for the forming die of the triangular plate of the civil air defense door leaf, the locking mechanism 3 includes a U-shaped frame 301, a bidirectional threaded rod 302, a secondary gear 303, two threaded blocks 304, two connecting plates 305, two insertion rods 306, two clamping frames 307, and two insertion holes 308.

The bidirectional threaded rod 302 is rotatably connected between the two sides of the inner wall of the U-shaped frame 301, and both ends of the bidirectional threaded rod 302 extend to the outside of the U-shaped frame 301. The secondary gear 303 is connected to the outer surface of the bidirectional threaded rod 302. Both of the two threaded blocks 304 are threadedly connected to the outer surface of the bidirectional threaded rod 302. The two connecting plates 305 are respectively connected to the bottoms of the two threaded blocks 304. The two insertion rods 306 are respectively connected to the adjacent surfaces of the two connecting plates 305. The two clamping frames 307 are respectively connected to the opposite surfaces of the two connecting plates 305. The two insertion holes 308 are respectively opened on both sides of the upper die 5, and the two insertion rods 306 are respectively movably inserted into the two insertion holes 308. The locking mechanism 3 further includes two guide rods 309 and two sliders 310. The two guide rods 309 are respectively connected to both sides of the mounting plate 2. The two sliders 310 are respectively slidably connected to the outer surfaces of the two guide rods 309, and the two sliders 310 are respectively connected to the fronts of the two connecting plates 305. The driving mechanism 4 includes a forward and reverse motor 401 and a main gear 402. The forward and reverse motor 401 is connected to the top of the mounting plate 2. The main gear 402 is connected to one end of the output shaft of the forward and reverse motor 401, and the main gear 402 meshes with the secondary gear 303.

[0027] Specifically, start the output shaft of the forward and reverse motor 401 to drive the main gear 402 to rotate. The main gear 402 drives the secondary gear 303 to drive the bidirectional threaded rod 302 to rotate, so that the two threaded blocks 304 rotate threadedly away from each other and drive the two sliders 310 to stably slide on the outer surfaces of the two guide rods 309 through the two connecting plates 305. At the same time, the two insertion rods 306 are withdrawn from the two insertion holes 308 to release the locking of the upper die 5, and at the same time, the two clamping frames 307 release the fixation of both sides of the upper die 5. The upper die 5 can fall naturally to complete the disassembly work. Place the upper die 5 back under the mounting plate 2 and reverse the forward and reverse motor 401 to insert the two insertion rods 306 back into the two insertion holes 308 and the two clamping frames 307 clamp and fix both sides of the upper die 5 again to complete the installation of the upper die 5.

[0028] Embodiment 3:

[0029] Please refer to Figures 1 to 4, in the embodiment of the present utility model, for the forming die of the triangular plate of the civil air defense door leaf, the pressing mechanism 6 includes a cross plate 601 and a pressing block 602. The cross plate 601 is connected to the bottom of the mounting plate 2, and the pressing block 602 is connected to the bottom of the cross plate 601. The buffer mechanism 7 includes a rubber column 701, a contact plate 702, and a damping spring 703. The rubber column 701 is connected to the bottom of the inner wall of one of the grooves, the contact plate 702 is connected to the top of the rubber column 701, and the contact plate 702 is located inside one of the grooves. The damping spring 703 is connected between the bottom of the inner wall of one of the grooves and the bottom of the contact plate 702, and the damping spring 703 is located outside the rubber column 701. A plurality of bases 8 are connected to the bottom of the workbench 1.

[0030] Specifically, the stamping assembly drives the upper die 5 to descend through the mounting plate 2 to stamp the steel plate. At the same time, the pressing block 602 at the bottom of the cross plate 601 contacts and presses the contact plate 702 to cause the rubber column 701 and the damping spring 703 to contract, buffering the pressure during stamping, thereby reducing the damage to the upper die 5. The stability of the device during operation can be improved through the arrangement of the plurality of bases 8.

[0031] The working principle of the present utility model is as follows: When it is necessary to quickly replace the upper die 5, the positive and negative motor 401 is started by the staff. The output shaft of the positive and negative motor 401 drives the main gear 402 to rotate. When the main gear 402 rotates, the driven gear 303 drives the bidirectional threaded rod 302 to rotate on the U-shaped frame 301, so that the two threaded blocks 304 rotate threadedly away from each other. When the two threaded blocks 304 move, they drive the two sliders 310 to slide stably on the outer surfaces of the two guide rods 309 through the two connecting plates 305 at the same time. And the two insertion rods 306 are withdrawn from the inside of the two insertion holes 308 to release the locking of the upper die 5. At the same time, the two connecting plates 305 drive the two clamping frames 307 to release the fixation of both sides of the upper die 5. At this time, the upper die 5 drops naturally to complete the disassembly work. The replaced upper die 5 is re-placed at the bottom of the mounting plate 2 and the positive and negative motor 401 is started in the reverse direction, so that the two insertion rods 306 are inserted into the inside of the two insertion holes 308 again and the two clamping frames 307 re-clamp and fix both sides of the upper die 5, thereby completing the installation of the upper die 5. When the stamping assembly drives the upper die 5 at the bottom of the mounting plate 2 to descend to stamp the steel plate, the pressing block 602 at the bottom of the cross plate 601 contacts and presses the contact plate 702. When the contact plate 702 is subjected to pressure, it squeezes the rubber column 701 and the damping spring 703 to contract, thereby buffering the pressure during stamping and reducing the influence of stress on the upper die 5 during the stamping process.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
