Description

Technical Field

[0001] This application relates to the field of burr removal devices, and more particularly to a burr removal device for the surface of a metal fire door. Background Art

[0002] Metal fire doors, also known as steel fire doors, are doors with a specified fire resistance performance, consisting of a door frame, door leaf skeleton, and door leaf panel made of steel materials. If the door leaf is filled with materials, it is filled with fireproof and heat-insulating materials that are non-toxic and harmless to the human body, and equipped with fireproof hardware accessories.

[0003] Metal fire doors have a wide and important application in modern buildings. During the manufacturing process of metal fire doors, it is necessary to polish the surface burrs to prevent workers from being scratched by burrs when moving or using the metal fire doors. However, due to the heavy weight and large size of metal fire doors, it is difficult to turn them over for polishing, making the polishing of the outer surface of metal fire doors inconvenient.

[0004] Regarding the aforementioned technologies, the inventors believe that metal fire doors have the drawback of being difficult to polish due to burrs.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a device for removing burrs from the surface of metal fire doors. (Refer to...) Figure 1 A burr removal device for the surface of a metal fire door includes a support base 1, which serves as a support for the entire device and is fixedly supported on the ground. A first connecting frame 3 and a second connecting frame 4 are rotatably connected to the upper surface of the support base 1 via two support shafts 2, so that the first connecting frame 3 and the second connecting frame 4 can rotatably support and connect two receiving frames 5 for use.

[0022] Meanwhile, the support base 1 is rotatably connected to two receiving frames 5 via two supporting pivots 2, in conjunction with the first connecting frame 3 and the second connecting frame 4. A fixing frame 6 is fixedly connected to the side wall of the receiving frame 5 via two reinforcing ribs 10. Furthermore, several receiving plates 9 are slidably connected between the receiving frame 5 and the fixing frame 6. This allows the metal fire door to be placed between the receiving frame 5 and the fixing frame 6 on one side during grinding and processing, with the metal fire door supported by the several receiving plates 9. The supporting bracket 5 and the fixed bracket 6 are tilted together, and then the supporting bracket 5 and the fixed bracket 6 on the other side are rotated. The metal fire door is clamped and limited by several supporting plates 9. In this way, the metal fire door is clamped and limited by several supporting plates 9 on both sides, and the several supporting plates 9 are limited and no longer slide at will. Finally, the supporting bracket 11 connected to the outer surface of the reinforcing rib 10 is tilted and supported, so as to facilitate the grinding of the metal fire door that is limited and clamped between several supporting plates 9.

[0023] Reference Figure 1 and Figure 3 Each of the reinforcing ribs 10 has a threaded hole 17 that penetrates its interior on its outer surface. The threaded holes 17 between two corresponding reinforcing ribs 10 are also positioned accordingly. At the same time, the threaded holes 17 between two corresponding reinforcing ribs 10 can be screwed together to connect to a threaded bolt 18. In this way, after the metal fire door is clamped and limited, the metal fire door can be fixed and limited by the threaded bolt 18 penetrating through the interior of the two threaded holes 17.

[0024] Reference Figure 3 and Figure 4 An extension plate 14 is fixedly connected to one side of the outer surface of the fixed frame 6, and several nozzles 16 are fixedly connected to the outer surface of the extension plate 14. The nozzles 16 are connected to an external water source through the extension plate 14. At the same time, a fixed support plate 15 is fixedly installed on the outer surface of the receiving frame 5, so that the metal fire door can be supported and placed by the fixed support plate 15 during processing. This facilitates tilting operation after the metal fire door is placed. Then, the receiving frame 5 and the fixed frame 6 on the other side cooperate with several receiving plates 9 to limit and clamp, so that when the metal fire door is polished, several nozzles 16 can spray water flow along the top of the vertically placed metal fire door to the side of its tilted polishing, which facilitates the deburring of the metal fire door.

[0025] Reference Figure 2 、 Figure 3 and Figure 4 Adjustment grooves 7 are provided on the outer surfaces of the receiving frame 5 and the fixed frame 6, and receiving plates 9 are fixedly connected to both ends of the outer surface of the adjusting frame 8. The adjusting frame 8 is also designed to be slidably connected to the inside of the adjusting groove 7, so that the receiving plates 9 can be slidably connected between the receiving frame 5 and the fixed frame 6. Furthermore, a buffer plate 12 is fixedly connected to one side of the outer surface of the receiving plate 9 by a snap fastener, so that the buffer plate 12 can replace the receiving plate 9 to contact the metal fire door, preventing the metal fire door from colliding with the receiving plate 9 and causing damage.

[0026] Reference Figure 1 and Figure 2 A connecting sleeve 13 is slidably connected to the outer surface of the reinforcing rib 10, and a support frame 11 is rotatably connected to the outer surface of the connecting sleeve 13. This allows the support frame 11 to be slidably and rotatably connected to the outer surface of the reinforcing rib 10. At the same time, a fixing screw is screwed onto the outer surface of the connecting sleeve 13 to facilitate the adjustment of the support frame 11. The support frame 11 supports the receiving frame 5, the fixing frame 6, and the metal fire door clamped inside them.

[0027] The implementation principle of the burr removal device for the surface of a metal fire door according to this application embodiment is as follows: By setting a support base 1, the support base 1 can serve as the support component for the entire device, and is fixedly supported on the ground. A first connecting frame 3 and a second connecting frame 4 are rotatably connected to the upper surface of the support base 1 via two support shafts 2, allowing the first connecting frame 3 and the second connecting frame 4 to rotatably support and connect two receiving frames 5. Simultaneously, the support base 1, through the two support shafts 2, rotatably connects the first connecting frame 3 and the second connecting frame 4 to the two receiving frames 5. A fixing frame 6 is fixedly connected to the side wall of the receiving frame 5 via two reinforcing ribs 10. Furthermore, several supports are slidably connected between the receiving frame 5 and the fixing frame 6. The connecting plate 9 allows the metal fire door to be placed between the receiving frame 5 and the fixing frame 6 on one side during grinding. The metal fire door is supported by several receiving plates 9, and the supported metal fire door is tilted together with the supporting receiving frame 5 and the fixing frame 6. Then, the receiving frame 5 and the fixing frame 6 on the other side are rotated, and the metal fire door is clamped and limited by several receiving plates 9. In this way, the metal fire door is clamped and limited by several receiving plates 9 on both sides, and the several receiving plates 9 are limited and no longer slide freely. Finally, the support frame 11, which is slidably and rotatably connected to the outer surface of the reinforcing rib 10, is tilted for support, which facilitates the grinding of the metal fire door that is limited and clamped between several receiving plates 9.
