Description

Technical Field

[0001] The present application relates to the technical field of light steel buildings, and in particular to a cutting device for light steel building roof panels. Background Art

[0002] There are usually two types of light steel structures: one is a skeleton structure composed of thin-walled steel sections cold-rolled from thin steel plates; the other is a skeleton structure composed of trusses made of steel sections with smaller cross-sections; and there is also a skeleton structure composed of a combination of the two methods. The widespread use of thin-walled steel sections in the skeleton structures of automobiles, aircraft and ships has promoted the development of light steel structures in industrialized system buildings.

[0003] During the construction of light steel buildings, the roof panels need to be cut using a cutting device. However, when ordinary cutting devices are used, the cutting blades will expose a lot of the upper surface of the cutting board. This is very dangerous when cutting wooden boards and can easily cause accidents. Therefore, we propose a cutting device for light steel building roof panels. Utility Model Content

[0035] Specifically, the indicator block 14 and the angle measuring range 4 are used together to show the rotation angle of the connecting platform 5 .

[0036] like Figure 3As shown: the slide rail 3 is semicircular, and the worm gear segment 15 is semicircular.

[0037] Specifically, the shapes of the slide rail 3 and the worm gear segment 15 are similar.

[0038] like Figure 1 As shown: the upper right side and the right side of the main body 1 are fixedly connected with a protective frame 7, the lower part of the inner cavity of the protective frame 7 is movably provided with a pressure plate 8, the front and rear sides of the upper end of the pressure plate 8 are symmetrically fixedly connected with sliding rods 9, the sliding rods 9 are movably inserted in the front and rear sides of the upper side wall of the protective frame 7, and the outer side of the sliding rod 9 is connected with a spring 10 between the pressure plate 8 and the upper side plate of the protective frame 7.

[0039] Specifically, the spring 10 is always in a compression state, and the spring 10 applies a downward force to the pressing plate 8 , so that the pressing plate 8 can stably compress the compression plate inserted at the lower end of the pressing plate 8 .

[0040] like Figure 5 As shown: a connecting ear plate 17 is fixedly connected to the middle part of the upper end of the connecting platform 5, a cutting knife 11 is rotatably connected to the middle part between the connecting ear plates 17, and a first motor 18 is fixedly connected to the end of the rotating shaft of the cutting knife 11, and the first motor 18 is fixedly connected to the outer side of the connecting ear plate 17.

[0041] Specifically, the first motor 18 adopts an existing motor on the market, which is a prior art. The first motor 18 is used to drive the cutting knife 11 to rotate.

[0042] like Figure 3 and Figure 5 As shown: the rotating shafts at both ends of the worm 20 are inserted into the middle of the lower end of the connecting platform 5 through bearings, one end of the worm 20 is fixedly connected to the second motor 16, and the second motor 16 is fixedly connected to the side of the connecting platform 5 through a bracket.

[0050] Principle of use: When the device is in use, firstly, according to the thickness of the cutting board, the second motor 16 is started, and the second motor 16 will drive the worm 20 to rotate forward or reversely. Since the worm 20 is meshed with the worm wheel segment 15, and the slider 19 and the slide slot 13 are limited (the slider 19 can only move in the slide slot 13), when the worm 20 rotates, the worm 20 will be driven to move along the worm wheel segment 15, and the connecting platform 5 will be driven to move, so that the cutting knife 11 will also be tilted and moved, so that the height of the cutting knife 11 extending out of the rectangular opening 6 can be adjusted, that is, the height of the cutting knife 11 extending out is slightly greater than the thickness of the cutting board, so that the cutting knife 11 will not expose a longer blade when cutting the board, so that the cutting knife 11 is safer when cutting the board, and the worm 20 is meshed with the worm wheel segment 15, and when the worm 20 stops rotating, the position of the worm 20 can be located without adding an external positioning mechanism;

[0051] When cutting a wooden board, insert the wooden board into the lower end of the pressing plate 8 from the inclined notch on the right side of the lower end of the pressing plate 8, and then manually push the cut wooden board to the left, so that the wooden board can be cut by the rotating cutting knife 11, and the cut wooden board continues to move to the left and moves to the lower end of the pressing plate 8 on the left, thereby making the cutting of the wooden board more stable. When cutting to the tail end of the wooden board, the tail end of the wooden board being cut can be pushed by another cut wooden board, so that the wooden board can be completely cut.

[0052] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
