[0034] 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.

[0035] This utility model provides, for example Figure 1-4 The steel bar clamping and stabilizing cutting equipment for building construction shown includes a cutting machine body 3 and a frame 1 set at the lower side of the cutting machine body 3;

[0036] Four casters are bolted to the four corners of the lower side of the frame. The casters are universal casters with brakes to facilitate the positioning and movement of the equipment. A drive motor 4 is located on the upper right side of the frame 1. An electric box 5 is located behind the drive motor 4. The drive motor 4 is powered by an external power source.

[0037] A fixed wall 8 is provided on the upper left side of the frame 1, a cutting opening 7 is provided on the rear side of the fixed wall 8, and a push switch 6 is provided on the outer rear side of the fixed arm.

[0038] A fixing plate 11 is provided on the left front side of the fixing wall 8, and a vertical slide rail groove (such as...) is opened in the middle of the front side of the fixing wall and the cutting machine body. Figure 1 As shown in Figure 19, the pressure roller is horizontally installed in the slide rail groove via the main rods on the left and right sides. The two ends of the main rod are fixed by welding connecting blocks, and the top of the connecting blocks is fitted with a rotating cylinder through a bearing sleeve. The inner wall of the rotating cylinder is provided with an internal thread hole that matches the threaded rod. The threaded rod is screwed into the rotating cylinder through the thread and extends to the outside of the equipment. The end is fixedly connected to a handle. A handle 9 is provided at the upper end of the threaded rod 10.

[0039] In this embodiment, the working principle of this construction rebar cutting equipment is that the drive motor 4 uses the belt inside the electric gearbox 5 as a transmission component to drive the main body 3 of the cutting machine to work. Simultaneously, through the coordinated action of components such as the fixed wall 8, the cutting opening 7, and the push-button switch 6, the rebar is precisely cut. The usage steps are as follows:

[0040] Place the steel bars to be cut inside frame 1 on the equipment and adjust their position to meet the requirements.

[0041] Start the drive motor 4, and the main body 3 of the cutting machine will begin to operate.

[0042] Adjust components such as the fixing plate 11 and pressure roller 12 as needed to ensure that the steel bar is firmly fixed at the cutting position.

[0043] Press switch 6 to start the cutting action.

[0044] After the reinforcing bar is cut, the drive motor 4 is stopped, and the cut reinforcing bar is removed after the main body of the cutting machine 3 has completely stopped. Through these steps, precise cutting of the reinforcing bar can be achieved, improving construction efficiency and accuracy.

[0045] like Figure 1-3 As shown, the left threaded rod 10 passes through the fixed plate 11 via a threaded connection, and the right threaded rod 10 passes through the left side of the cutting machine body 3 via a threaded connection. The rotating cylinder 17 is connected to the lower side of the threaded rod 10 via a nested connection, and the rotating cylinder 17 can rotate on the lower side of the threaded rod 10. The connecting block 16 is connected to the rotating cylinder 17 via an integrated connection. The main rod 15 is connected to the rotating cylinder 17 and the pressure roller 12 via nested and integrated connections, respectively. The pressure roller 12 can rotate inside the rotating cylinder 17 via the main rod 15. A slide rail 19 is provided at the connection position between the main rod 15 and the left outer wall of the cutting machine body 3 and the fixed wall 8. The threaded rod 10 can move up and down within the fixed plate 11 and the cutting machine body 3 via threads, and the pressure roller 12 can move up and down within the slide rail 19 via the two main rods 15.

[0046] Preferably, the operator can place the steel bar to be cut into the cutting opening 7 on the frame 1.

[0047] Hold the two handles 9 and rotate the threaded rod 10 to move the threaded rod 10 up and down within the fixed plate 11 and the main body of the cutting machine 3, ensuring that the steel bar is firmly fixed in the cutting position.

[0048] Adjust the position of the pressure roller 12 within the slide rail 19 so that the pressure roller 12 presses down on the placed steel bar to ensure that the steel bar does not move.

[0049] Turn on the main body 3 of the cutting machine and use the cutting port 7 to complete the cutting operation of the steel bar.

[0050] During the process of cutting multiple sections of steel bars, the steel bars can be conveyed forward by the pressure roller 12 through the rotation of the main rod 15 inside the rotating cylinder 17 to complete the conveying task, so as to continuously cut multiple sections of steel bars.

[0051] Through these operational steps, workers can efficiently complete the cutting of steel bars, improving construction efficiency and accuracy.

[0052] like Figure 1-2 as well as Figure 4As shown, a base plate 14 is provided below the left side space of the fixed wall 8 and the main body of the cutting machine 3. A T-shaped sliding groove extending forward and backward is opened on the upper surface of the frame. A slider is fixedly connected to the lower rear side of the base plate by bolts, and the slider slides in cooperation with the T-shaped sliding groove. A handle is welded to the front side of the base plate to facilitate pulling the base plate out for cleaning. A handle 13 is provided at the outer front side of the base plate 14.

[0053] Preferably, during the cutting of reinforcing bars, the spatter generated will be intercepted by the fixed wall 8 and the outer wall of the cutting machine body 3, remaining outside the cutting opening 7, which may obstruct the entry of the next section of reinforcing bar to be cut. At this time, the operator can hold the handle 13 and pull out the base plate 14 through the slider 18 to quickly clean the residue on the base plate 14, avoiding the dangerous situation caused by accidentally pressing the switch 6 during manual cleaning.

[0054] Slide rail groove: A vertical guide groove with a rectangular cross-section, located on the fixed wall and the front side of the cutting machine body, used to limit the movement trajectory of the main rod and ensure the vertical lifting and lowering of the pressure roller.

[0055] Bearing sleeve connection: The rotating cylinder is sleeved on the lower end of the threaded rod through a deep groove ball bearing, so that the rotating cylinder can rotate freely around the threaded rod. At the same time, the up and down movement of the threaded rod drives the rotating cylinder to rise and fall synchronously.

[0056] When the handle 9 is rotated, the threaded rod 10 moves up and down along the threaded holes of the fixed plate 11 and the main body 3 due to the threaded transmission, driving the connecting block 16 and the main rod 15 to rise and fall synchronously through the rotating cylinder 17. Since the main rod can only move vertically due to the restriction of the slide rail groove 19, the pressure roller 12 presses or releases the steel bar accordingly. During cutting, the frictional force of the steel bar being conveyed forward drives the pressure roller to rotate on the bearing inside the rotating cylinder through the main rod, achieving continuous feeding.

[0057] These operating procedures and safety measures ensure the normal use of the equipment and improve construction efficiency and safety. Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the scope of the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
