When using steel bar materials, a cutting device is usually used to cut long steel bars.

[0003] In the Chinese utility model patent with the publication number of CN219817869U, a steel bar cutting device for building construction is disclosed, which includes a workbench. A cutting groove is formed on the upper surface of the workbench. A cutting machine for cutting steel bars is arranged on the upper surface of the workbench. A connecting plate is fixed on the upper surface of the workbench. A sliding groove is formed on the upper surface of the workbench. A sliding plate is slidably arranged in the sliding groove. A clamping device for clamping steel bars is arranged on the upper surface of the sliding plate. A sliding slot is formed on the upper surface of the workbench. A sliding block is slidably arranged in the sliding slot. A stabilizing plate is fixed on the upper surface of the sliding block. Mounting holes matching the steel bars are formed on the side walls of the connecting plate and the stabilizing plate. A limiting component for limiting the steel bars is arranged on the workbench.

[0004] Regarding the above related technology, the inventor believes that there are the following defects: during the process of cutting steel bars, debris and sparks will be generated. The flying debris and sparks will not only pollute the cutting environment, but also easily burn the staff, posing a certain safety hazard. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides a steel bar cutting device for building construction.

[0006] The above technical object of the utility model is achieved by the following technical solutions: A steel bar cutting device for building construction, including a cutting box, a box cover is hinged on the side wall of the cutting box, a lower arc-shaped hole is opened at the intersection between the side wall of the cutting box and the upper surface of the cutting box, an upper arc-shaped hole matching the lower arc-shaped hole is opened at the intersection between the side wall of the box cover and the bottom of the box cover, a cylinder is fixed on the upper surface of the box cover, the piston rod of the cylinder penetrates through the upper surface of the box cover and is slidably connected, and a cutting machine for cutting steel bars is fixed at the end of the piston rod of the cylinder. A fixing component for fixing the steel bar is installed on the box cover. A slot is opened at the intersection between the upper surface of the cutting box and the side wall of the cutting box, and a plug block inserted and matched with the slot is fixed at the bottom of the box cover. A limiting component for limiting the plug block is installed on the cutting box.

[0007] By adopting the above technical solutions, when cutting steel bars, the staff places the steel bar on the lower arc-shaped hole so that the position to be cut is below the cutting machine and closes the box cover, makes the plug block inserted and matched with the slot and limits the plug block through the limiting component, thereby fixing the box cover, then fixes the steel bar through the fixing component, and cuts the steel bar through the cylinder and the cutting machine. The debris and sparks generated during the cutting process are blocked by the cutting box and the box cover, avoiding the situation of debris and sparks splashing and improving the safety of the cutting device.

[0008] Furthermore, the fixing component includes a threaded rod penetrating through and threadedly connected to the box cover, a star-shaped handle fixed to the upper end of the threaded rod, a fixing block rotatably connected to the lower end of the threaded rod, and a limiting block fixed to the side wall of the fixing block and slidably connected to the inner wall of the box cover. An arc-shaped groove is opened at the bottom of the fixing block.

[0009] By adopting the above technical solutions, after closing the box cover, the staff rotates the threaded rod through the star-shaped handle. Since the threaded rod is threadedly connected to the box cover, the threaded rod is rotatably connected to the fixing block, and the fixing block is slidably connected to the inner wall of the box cover through the limiting block, the circumferential rotation of the fixing block is restricted by the limiting block, so that the fixing block moves downward along the axial direction of the threaded rod, making the arc-shaped groove press down tightly on the steel bar and fixing it, enhancing the stability during steel bar cutting.

[0010] Furthermore, an installation groove is opened on the inner wall of the slot, a limiting hole matching the installation groove is penetrated and opened on the side wall of the plug block, the limiting component includes a limiting rod slidably connected to the inner wall of the installation groove and inserted and matched with the limiting hole, and a spring arranged in the installation groove. One end of the spring is fixed to the end of the limiting rod, and the other end of the spring is fixed to the inner wall of the installation groove.

[0011] By adopting the above technical solution, the limit rod remains in an inserted state with the limit hole under the elastic force of the spring, thereby limiting the insertion block and keeping the box cover closed. When the box cover needs to be opened, the staff presses the limit rod inward to disengage the limit rod from the limit hole, thereby rotating the box cover upward to open it.

[0012] Furthermore, the upper surface of the limiting rod is provided with a yielding portion which cooperates with the bottom of the insert block.

[0013] By adopting the above technical solution and setting the yielding part, the plug block can squeeze the limit rod into the installation groove through the yielding part during the process of inserting the slot, and then the limit rod is automatically inserted into the limit hole under the elastic force of the spring, eliminating the tedious operation of the staff to manually press the limit rod, and facilitating the quick closing of the box cover.

[0014] Furthermore, a sliding groove is provided in the bottom wall of the installation groove, a pressing groove connected to the sliding groove is provided in the side wall of the cutting box, a connecting rod is fixed to the bottom of the limiting rod and is slidably connected to the inner wall of the sliding groove, and a control block is fixed to the side wall of the connecting rod and is slidably connected to the inner wall of the pressing groove.

[0015] By adopting the above technical solution, when the box cover needs to be opened, the staff only needs to press the control block inward to make the connecting rod drive the limit rod to move inward, thereby making the limit rod disengage from the limit hole, releasing the limiting effect on the plug block, and facilitating the quick opening of the box cover.

[0016] Furthermore, a U-shaped rod is fixed to the side wall of the box cover.

[0017] By adopting the above technical solution, the setting of the U-shaped rod provides a fulcrum for the box cover, making it convenient for the staff to open or close the box cover by holding the U-shaped rod.

[0018] Furthermore, a rubber pad is fixed to the inner wall of the arc-shaped groove.

[0019] By adopting the above technical solution, the rubber pad is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the arc-shaped groove and the steel bar and enhances the fixing effect on the steel bar.

[0020] Furthermore, a transparent window is provided on the side wall of the box cover.

[0021] By adopting the above technical solution and setting up the transparent window, the staff can observe the steel bars through the transparent window, so as to monitor the cutting status of the steel bars.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In the present application, when it is necessary to cut the steel bar, the staff will place the steel bar on the lower arc hole so that the position to be cut is below the cutting machine and close the box cover, so that the plug block is plugged into the slot and the plug block is limited by the limit assembly, thereby fixing the box cover, and then fixing the steel bar by the fixing assembly, and cutting the steel bar by the cylinder and the cutting machine. The debris and sparks generated during the cutting process are blocked by the cutting box and the box cover, avoiding the situation of debris and sparks splashing, and improving the safety of the cutting device;

[0024] 2. In the present application, after closing the box cover, the staff rotates the threaded rod through the star-shaped handle. Since the threaded rod is threadedly connected to the box cover, the threaded rod is rotatably connected to the fixed block, and the fixed block is slidably connected to the inner wall of the box cover through the limit block, the circumferential rotation of the fixed block is limited by the limit block, so that the fixed block moves downward along the axial direction of the threaded rod, so that the arc-shaped groove presses against the steel bar downward and fixes it, thereby enhancing the stability when cutting the steel bar;

[0025] 3. In the present application, the limit rod remains plugged into the limit hole under the elastic force of the spring, thereby limiting the plug block and keeping the box cover closed. When the box cover needs to be opened, the staff presses the limit rod inward to disengage the limit rod from the limit hole, thereby rotating the box cover upward to open it.

An arc-shaped hole 11 is opened at the intersection between the side wall of the cutting box 1 and the upper surface of the cutting box 1. A slot 12 is opened at the intersection between the upper surface of the cutting box 1 and the side wall of the cutting box 1. An installation groove 13 is opened on the inner wall of the slot 12. The box cover 2 is a cuboid structure with an open bottom. The box cover 2 is hinged on the side wall of the cutting box 1. An arc-shaped hole 21 that cooperates with the lower arc-shaped hole 11 is opened at the intersection between the side wall of the box cover 2 and the bottom of the box cover 2. The cylinder 3 is fixed on the upper surface of the box cover 2. The piston rod of the cylinder 3 penetrates through the upper surface of the box cover 2 and is slidably connected. The cutting machine 31 is a cutting machine 31 commonly used in the prior art and applicable to this embodiment. The cutting machine 31 is fixed at the end of the piston rod of the cylinder 3 and is used for cutting steel bars.

[0034] The fixing component 4 is installed on the box cover 2 and is used for fixing steel bars. The fixing component 4 includes a threaded rod 41, a star-shaped handle 42, a fixing block 43, and a limiting block 44. The threaded rod 41 is a rod-shaped structure arranged vertically. The threaded rod 41 penetrates through the box cover 2 and is threadedly connected. The star-shaped handle 42 is fixed at the upper end of the threaded rod 41, and the axis of the star-shaped handle 42 coincides with the axis of the threaded rod 41. The fixing block 43 is a cuboid structure. The fixing block 43 is fixedly connected to the lower end of the threaded rod 41. An arc-shaped groove 431 is opened at the bottom of the fixing block 43. The limiting block 44 is a cuboid structure. The limiting block 44 is fixed on the side wall of the fixing block 43 and is slidably connected to the inner wall of the box cover 2.

[0035] The insertion block 5 is a cuboid structure. The insertion block 5 is fixed at the bottom of the box cover 2. The insertion block 5 is inserted and matched with the slot 12. A limiting hole 51 that cooperates with the installation groove 13 is opened through the side wall of the insertion block 5. The limiting component 6 is installed on the cutting box 1 and is used for limiting the insertion block 5. The limiting component 6 includes a limiting rod 61 and a spring 62. The limiting rod 61 is a rod-shaped structure arranged horizontally. The limiting rod 61 is slidably connected to the inner wall of the installation groove 13 and is inserted and matched with the limiting hole 51. The spring 62 is arranged in the installation groove 13. One end of the spring 62 is fixed to the end of the limiting rod 61, and the other end of the spring 62 is fixed to the inner wall of the installation groove 13.

[0036] When it is necessary to cut the steel bars, the staff places the steel bars on the lower arc hole 11 so that the position to be cut is under the cutting machine 31 and closes the box cover 2, presses the limit rod 61 inward to make the limit rod 61 enter the installation groove 13, and after the plug block 5 is plugged into the slot 12, the limit rod 61 pops out under the elastic force of the spring 62 and plugs into the limit groove to limit the plug block 5, thereby fixing the box cover 2, and then rotates the threaded rod 41 through the star-shaped handle 42. Since the threaded rod 41 is threadedly connected to the box cover 2, the threaded rod 41 is rotatably connected to the fixing block 43, and the fixing block 43 is slidingly connected to the inner wall of the box cover 2 through the limit block 44, so that the fixing block 43 is The circumferential rotation is limited by the limit block 44, so that the fixed block 43 moves downward along the axial direction of the threaded rod 41, so that the arc groove 431 presses downward against the steel bar and fixes it, thereby enhancing the stability during the cutting of the steel bar. The steel bar is cut by the cylinder 3 and the cutting machine 31. The debris and sparks generated during the cutting process are blocked by the cutting box 1 and the box cover 2, thereby avoiding the splashing of debris and sparks and improving the safety of the cutting device. After the cutting is completed, the staff rotates the star-shaped handle 42 in the opposite direction to move the fixed block 43 away from the steel bar, presses the limit rod 61 inward, so that the limit rod 61 disengages from the limit hole 51, and then rotates the box cover 2 upward to open it, so as to facilitate the removal of the cut steel bar.

[0037] In order to facilitate the rapid closing of the box cover 2, a yielding portion 611 is provided on the upper surface of the limit rod 61, which cooperates with the bottom of the plug block 5. The setting of the yielding portion 611 enables the plug block 5 to squeeze the limit rod 61 into the installation groove 13 through the yielding portion 611 during the insertion process of the slot 12. Then, the limit rod 61 is automatically inserted into the limit hole 51 under the elastic force of the spring 62, eliminating the tedious operation of the staff to manually press the limit rod 61, thereby facilitating the rapid closing of the box cover 2.

[0038] In order to facilitate the rapid opening of the box cover 2, a sliding groove 14 is provided on the inner bottom wall of the mounting groove 13, and a pressing groove 15 connected to the sliding groove 14 is provided on the side wall of the cutting box 1. A connecting rod 7 is fixed to the bottom of the limiting rod 61 and is slidably connected to the inner wall of the sliding groove 14. A control block 8 is fixed to the side wall of the connecting rod 7 and is slidably connected to the inner wall of the pressing groove 15. When it is necessary to open the box cover 2, the staff only needs to press the control block 8 inward to make the connecting rod 7 drive the limiting rod 61 to move inward, thereby making the limiting rod 61 disengage from the limiting hole 51, thereby releasing the limiting effect on the insert block 5, thereby facilitating the rapid opening of the box cover 2.

[0039] In order to facilitate opening or closing the box cover 2, a U-shaped rod 9 is fixed to the side wall of the box cover 2. The setting of the U-shaped rod 9 provides a fulcrum for the box cover 2, so that the staff can open or close the box cover 2 by holding the U-shaped rod 9.

The rubber pad 10 is made of rubber material, and its surface has a large friction coefficient, which increases the friction force between the arc-shaped groove 431 and the steel bar, thereby enhancing the fixing effect on the steel bar.

[0041] In order to facilitate the monitoring of the cutting condition of the steel bar, a transparent window 22 is provided on the side wall of the box cover 2. The setting of the transparent window 22 enables the staff to observe the steel bar through the transparent window 22, thus facilitating the monitoring of the cutting condition of the steel bar.

[0042] The working principle of a steel bar cutting device for building construction in this embodiment is as follows: When cutting a steel bar, the staff places the steel bar on the lower arc-shaped hole 11 so that the position to be cut is under the cutting machine 31 and closes the box cover 2. Press the limiting rod 61 inward so that the limiting rod 61 enters the installation groove 13. After the inserting block 5 is inserted and matched with the inserting slot 12, the limiting rod 61 pops out under the elastic force of the spring 62 and is inserted and matched with the limiting slot to limit the inserting block 5, thereby fixing the box cover 2. Then, rotate the threaded rod 41 through the star-shaped handle 42. Since the threaded rod 41 is threadedly connected to the box cover 2 and the threaded rod 41 is rotatably connected to the fixed block 43, and the fixed block 43 is slidably connected to the inner wall of the box cover 2 through the limiting block 44, the circumferential rotation of the fixed block 43 is restricted by the limiting block 44, so that the fixed block 43 moves downward along the axial direction of the threaded rod 41, making the arc-shaped groove 431 press down and fix the steel bar, enhancing the stability during the steel bar cutting. The steel bar is cut by the cylinder 3 and the cutting machine 31. The debris and sparks generated during the cutting process are blocked by the cutting box 1 and the box cover 2, avoiding the situation of debris and sparks splashing, and improving the safety of the cutting device. After the cutting is completed, the staff rotates the star-shaped handle 42 in the reverse direction to make the fixed block 43 away from the steel bar, press the limiting rod 61 inward, so that the limiting rod 61 disengages from the limiting hole 51, and then rotate the box cover 2 upward to facilitate the removal of the cut steel bar.
