Description

Technical Field

[0001] This utility model relates to the technical field of civil defense door leaf production, specifically to an automated production device for civil defense door leaves. Background Technology

[0002] Civil defense door panels refer to the door panels used in civil defense projects. With the development of materials technology, in order to avoid corrosion of civil defense equipment, the steel edging of traditional reinforced concrete civil defense door panels has been removed. Removing the steel edging during the manufacturing of civil defense door panels usually requires the use of molds to shape the panels.

[0003] A search revealed a utility model patent in China with publication number CN216760300U: an automated production device for air-raid shelter doors, comprising a door mold, which includes side molds and a bottom mold. The side molds include a first side mold, a second side mold, a third side mold, and a fourth side mold. All four side molds are slidably mounted above the bottom mold and can be closed into a rectangle. The bottom mold includes a top plate for supporting the side molds and a drive mounting base for mounting a drive device. A cylinder pusher mounted on the drive mounting base pushes the four side molds to move above the bottom mold, facilitating smooth mold closing and demolding during air-raid shelter door production. In use, the cylinder pusher drives the side molds closer together, closing them into a rectangle. Then, the reinforcing cage and embedded parts are placed into the mold and fixed. Concrete is then poured and vibrated, and after steam curing, the corresponding side molds are moved by the cylinder pusher for demolding.

[0004] Regarding the aforementioned technologies, the side mold is prone to deformation after demolding during long-term use. Operators often find it difficult to judge the deformation of the side mold, resulting in the inability to handle and replace it in a timely manner. This causes the shape of the subsequently poured civil defense door leaf to not meet the design requirements. Therefore, an automated production device for civil defense door leaves is needed to improve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Please see Figure 1 and Figure 2 An automated production device for air defense door panels includes an upper template 1. Two first fixing plates 2 and two second fixing plates 12 are symmetrically fixedly installed on the upper template 1. Each of the two first fixing plates 2 is provided with a first adjustment mechanism, and each of the two second fixing plates 12 is provided with a second adjustment mechanism.

[0031] Please see Figure 1-5 One of the first adjustment mechanisms includes a first side plate 5. Two first electric push rods 3 are symmetrically fixedly installed on a first fixed plate 2. The two first electric push rods 3 are connected by a first moving plate 4. When the two first electric push rods 3 are activated, the two first electric push rods 3 drive the first moving plate 4 and the first side plate 5 to move. The first moving plate 4 and the first side plate 5 are connected by a connecting assembly, which also includes two locking blocks 7. Two sliders 6 are symmetrically fixedly installed on the first moving plate 4. Two first sliding grooves are symmetrically opened on the first side plate 5. The two sliders 6 are slidably connected to the two first sliding grooves respectively. Each slider 6 has a locking groove. Two second sliding grooves are symmetrically opened on the first side plate 5. The two locking blocks 7 are slidably connected to the two second sliding grooves respectively. The two locking blocks 7 are locked into the two locking grooves respectively. An L-shaped plate 8 is fixedly installed on each of the two locking blocks 7. A spring 9 is fixedly installed at the bottom of each of the two L-shaped plates 8. The other end of each of the two springs 9 is fixedly connected to the second sliding groove.

[0032] Please see Figure 3 and Figure 4Each spring 9 is provided with a limit component, which includes two telescopic columns 10. The two telescopic columns 10 are respectively fitted onto the two springs 9. The two telescopic columns 10 are symmetrically fixedly installed in the two second sliding grooves. The other end of the two telescopic columns 10 is fixedly connected to the corresponding L-shaped plate 8. The setting of the two telescopic columns 10 makes the two springs 9 more stable, thereby making the two L-shaped plates 8 more stable.

[0033] Please see Figure 1-4 Two L-shaped plates 8 are connected by a connecting plate 11, and two second sliding grooves are connected by a third sliding groove. The connecting plate 11 is slidably connected to the third sliding groove. A second mounting plate 21 is fixedly installed on the connecting plate 11. The first moving plate 4 is connected to the first side plate 5. Pressing the connecting plate 11 causes the connecting plate 11 to move the two L-shaped plates 8 and the two locking blocks 7. At this time, the two springs 9 are compressed, and the two sliders 6 are slid so that the two sliders 6 are located inside the two first side plates 5. The connecting plate 11 is released, and the two locking blocks 7 are reset by the elastic force of the two springs 9, so that the two locking blocks 7 are locked with the two sliders 6, thereby realizing the connection operation of the first moving plate 4 and the first side plate 5.

[0034] Please see Figure 1 and Figure 2 One of the second adjustment mechanisms includes a second side plate 15. A second electric push rod 13 is fixedly installed on the second fixed plate 12. A second moving plate 14 is fixedly installed on the second electric push rod 13. The second moving plate 14 and the second side plate 15 are also connected by a connecting assembly of the first moving plate 4 and the first side plate 5. Distance detectors 16 are symmetrically fixedly installed on both first fixed plates 2 and both second fixed plates 12. Similarly, after the second moving plate 14 and the second side plate 15 are installed and adjusted, a mold is formed by the cooperation of the two first side plates 5 and the two second side plates 15 to produce the door leaf. After demolding, multiple first electric push rods 3 and multiple second electric push rods 13 drive the corresponding first side plates 5 and second side plates 15 to reset. Multiple distance detectors 16 detect the distance between the two ends of the first side plates 5 and the second side plates 15 and the first moving plate 4 and the second moving plate 14. If the error is large, it indicates that the first side plates 5 and the second side plates 15 have been deformed, which makes it easy for the staff to find and replace them in time to prevent defective products.

[0035] Please see Figure 5 The two first movable plates 4 are equipped with stabilizing mechanisms for stabilizing the operation of the first movable plates 4. The stabilizing mechanisms include two limiting blocks 17, which are symmetrically fixedly installed on the first movable plates 4. Two limiting grooves are symmetrically opened on the first fixed plate 2, and limiting rods 18 are fixedly installed in each of the two limiting grooves. The two limiting blocks 17 are slidably connected to the two limiting rods 18 respectively. The setting of the two limiting rods 18 and the two limiting blocks 17 makes the first movable plate 4 more stable when moving.

[0036] Please see Figure 1 and Figure 2 It should also be noted that the first movable plate 4 and the first side plate 5 are fixed by a fixing mechanism, one of which includes a first mounting plate 20, which is fixedly mounted on the first movable plate 4. A second mounting plate 21 is fixedly mounted on the first side plate 5. The first mounting plate 20 and the second mounting plate 21 are connected by bolts 22. The connection of the first mounting plate 20 and the second mounting plate 21 makes the connecting plate 11 more stable, thereby making the two clamping blocks 7 and the two L-shaped plates 8 more stable.

[0037] Please see Figure 1 and Figure 2 The corners of the upper template 1 are set as arc-shaped structures 19. The setting of multiple arc-shaped structures 19 reduces the sharpness of the upper template 1 and protects the workers during operation.

[0038] In summary, when using this automated production device for the air-raid shelter door leaf, the first moving plate 4 is connected to the first side plate 5. The corresponding second mounting plate 21 presses down on the connecting plate 11, causing the connecting plate 11 to move the two L-shaped plates 8 and the two locking blocks 7. At this time, the two springs 9 are compressed, and the two sliders 6 slide, positioning them inside the two first side plates 5. Releasing the connecting plate 11 allows the springs 9 to reset the two locking blocks 7, thus engaging them with the sliders 6. This achieves the connection between the first moving plate 4 and the first side plate 5. By sequentially rotating the corresponding bolts 22, the corresponding first mounting plate 20 and second mounting plate 21 are connected, further stabilizing the multiple locking blocks 7 and multiple L-shaped plates 8. Two first electric push rods 3 are moved, which in turn drive the first moving plate 4 and the first side plate 5 to move. Similarly, the second moving plate 14 and the second side plate 15 are installed and adjusted. The two first side plates 5 and the two second side plates 15 cooperate to form a mold for door leaf production. After demolding, multiple first electric push rods 3 and multiple second electric push rods 13 drive the corresponding first side plates 5 and second side plates 15 to reset. Multiple distance detectors 16 detect the distance between the two ends of the first side plates 5 and the second side plates 15 and the first moving plate 4 and the second moving plate 14. When the data error between the two corresponding distance detectors 16 is large, it indicates that the first side plate 5 or the second side plate 15 has been deformed, which can be easily detected and replaced by the staff in time to prevent defective products.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
