Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a self-propelled equal-length cutting device for steel bars used in construction engineering. Background Art

[0002] Rebar is a kind of building material. It is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. The cooperation between the steel bars can improve the strength of the building. In practical applications, the steel bars need to be cut into different lengths according to the usage. At present, when cutting the steel bars for construction projects, especially when some equal-length steel bars are needed, the length needs to be marked first, and then the workers use handheld electric saws to cut the steel bars, which has low work efficiency and safety.

[0003] After searching, Chinese Patent Publication (Announcement) No. 201921320174.0 discloses a self-propelled equal-length cutting device for steel bars for construction projects. The patent adjusts the position of the cutting blade according to the length of the required steel bar segment, so that the steel bar body can be cut into small segments of the same length. The operation is simple. Although the above patent has the function of cutting equal lengths, it does not have the function of blocking debris during cutting. After the cutting blade contacts the steel bar, not only will downward residues be produced, but also sparks and debris will be generated to one side. If the debris is not effectively blocked, it will cause trouble to clean up the high-temperature residues in the surrounding area. The blocking structure can be extended and retracted up and down to facilitate the loading and unloading of steel bars, and the current cutting device is not convenient for quickly fixing the steel bars. Therefore, it is necessary to design a self-propelled equal-length cutting device for steel bars for construction projects. Utility Model Content

[0026] In this embodiment, a column 9 is fixedly connected to one side of the table top 1, a slide 10 is fixedly connected to the top of the column 9, a threaded column 11 is rotatably connected to the inner wall of the slide 10, and a second motor is installed at one end of the slide 10.

[0027] During specific use, the second motor can drive the threaded column 11 to rotate after being started, which has a transmission effect, making it easier for the slider 13 to be subjected to the force of the thread.

[0028] In this embodiment, the outer surface of the threaded column 11 is threadedly connected with a slider 13, the slider 13 is slidably connected to the slide seat 10, the lower surface of the slider 13 is fixedly connected with a cylinder, and the output end of the cylinder is fixedly connected to the cutting machine 2.

[0029] During specific use, the threaded column 11 can drive the slider 13 to slide in the slide seat 10 after rotating, so that the cylinder can adjust different positions. The cylinder drives the cutter 2 to extend downward to contact the steel bar body 21, thereby achieving a cutting effect.

[0030] In this embodiment, a scale plate 14 is fixedly connected to the middle of the upper surface of the table top 1, and a bottom plate 15 is fixedly connected to one side of the upper surface of the table top 1. There are two bottom plates 15, and a steel bar body 21 is movably connected to the upper surface of the bottom plate 15.

After the pressing plate 16 is released, the oblique clamping teeth are clamped on the ratchet 17, which can prevent the rotating shaft from rotating and loosening the pressing plate 16, thereby quickly fixing the steel bar body 21, starting the first motor 5, driving the screw rod 6 to rotate forward, and through the threaded connection effect of the screw rod 6 and the slide plate 7, the slide plate 7 and the guide column 8 have a sliding effect, so that the slide plate 7 is affected After receiving the threaded force of the screw rod 6, it moves upward, driving the baffle 4 to extend out from the movable groove 3. After the threaded column 11 rotates, it can drive the slider 13 to slide in the slide seat 10, which is convenient for the cylinder to adjust different positions. The cutting machine 2 is driven by the cylinder to extend downward to contact the steel bar main body 21, thereby having a cutting effect. The baffle 4 can effectively reduce the splashing of debris to one side during the cutting process, and has the function of blocking debris. After the cutting is completed, the first motor 5 is started again to drive the screw rod 6 to reverse, which can make the slide plate 7 drive one side of the baffle 4 downward, so that the baffle 4 shrinks downward from the movable groove 3, and the limit column 18 is pulled downward to make the oblique clamping tooth disengage from the ratchet 17. Through the rebound effect of the torsion spring, the rotating shaft can be driven to reverse and reset, so that the pressure plate 16 is automatically loosened to facilitate the removal of the steel bar main body 21.
