DETAILED DESCRIPTION

[0027] This application provides a construction engineering steel bar cutting and processing equipment, hereinafter referred to as this equipment, please refer to Figure 1 The device comprises a platform 1, a fixing mechanism and a cutting mechanism. The platform 1 is the load-bearing mechanism of the device, and the fixing mechanism and the cutting mechanism are both installed on the surface of the platform 1.

[0028] Please refer to Figure 1 and Figure 3 The fixing mechanism is provided with at least two rebar flattening positions. These positions are used to lay the rebar flat and relatively secure it. The rebar can be laid flat on the flattening positions, and the fixing mechanism can keep the rebar relatively securely placed flat on the working positions. The fixing mechanism can secure the rebar by, but is not limited to, clamping. During the cutting process, the cutting mechanism can maintain the rebar in different positions as much as possible, facilitating a smooth cutting process.

[0029] Regarding the cutting mechanism, the cutting mechanism is provided with a cutting assembly, a transverse moving assembly 12 and a lifting assembly 13 .

[0030] Please refer to Figure 4 The cutting assembly includes a slide 9, a first motor 6, and a cutting wheel 7. The first motor 6 is mounted on the slide 9, and the cutting wheel 7 is connected to the first motor 6. The first motor 6 drives the cutting wheel 7 to rotate to cut the steel bars. The cutting wheel 7 and the first motor 6 can move with the slide 9. The slide 9 can realize the functional limitation of moving the cutting wheel 7 from directly above one steel bar flat position to directly above another steel bar flat position. The slide 9 has a threaded hole running through the thickness direction. The threaded hole on the slide 9 is the key to its lateral movement.

[0031] Please refer to Figure 1 and Figure 2 The lateral moving assembly 12 is provided with a moving frame 122, a second motor 10, a screw 11 and a fixed plate 121. The second motor 10 is mounted on the moving frame 122. The screw 11 is driven and connected to the second motor 10. The fixed plate 121 is connected to the moving frame 122, and the fixed plate 121 is rotatably connected to the end of the screw 11 away from the second motor 10, so that the screw 11 is mounted between the second motor 10 and the fixed plate 121, and the screw 11 is driven and rotated by the second motor 10. Based on the above-mentioned slide 9, a threaded hole is provided along the thickness direction. The screw 11 is passed through the slide 9, and the screw 11 is threadedly connected to the slide 9 in the threaded hole. The length direction of the screw 11 is the same as the arrangement direction of at least two steel bar flattening positions. When the screw 11 moves, the slide 9 moves along the length direction of the screw 11, thereby realizing the functional limitation of the cutting wheel 7 moving from directly above one steel bar flattening position to directly above another steel bar flattening position.

[0032] Please refer to Figure 2 The lifting assembly 13 is installed relative to the platform 1, and the lifting assembly 13 is connected to the movable frame 122. The height of the movable frame 122 is adjusted by the lifting assembly 13. When the height of the movable frame 122 changes, it also means that the height of the horizontal moving assembly 12 changes, thereby driving the cutting wheel 7 in the cutting assembly to move in the height direction.

[0033] The lifting assembly 13 controls the lateral movement assembly 12 to be raised and lowered, so that the cutting wheel 7 can be moved down to the steel bar position to achieve cutting of the steel bar. When the second motor 10 in the lateral movement assembly 12 drives the screw 11 to rotate, the slide 9 can move along the length direction of the screw 11. Under the condition that the length direction of the screw 11 is the same as the arrangement direction of at least two steel bar flat positions, the cutting wheel 7 located on the slide 9 can be moved from directly above one steel bar flat position to directly above other steel bar flat positions, so as to achieve cutting of at least two steel bars on the fixed mechanism. This device adopts a driving method in which the second motor 10 drives the screw 11 to drive the slide 9 to move horizontally, which is conducive to the stable lateral movement process of the cutting assembly, avoids the operational inconvenience and safety hazards of manually moving the cutting wheel 7 horizontally when cutting and truncation of multiple steel bars, and significantly improves the working efficiency and safety in actual application.

[0034] In some embodiments, see Figure 1The movable frame 122 is provided with a movable groove 123, which penetrates along the thickness direction of the movable frame 122. The length direction of the movable groove 123 is the same as the length direction of the screw rod 11. The slide plate 9 is slidably mounted in the movable groove 123. When the screw rod 11 rotates, the slide plate 9 slides along the movable groove 123. In this embodiment, the second motor 10 is mounted on the upper side of the movable frame 122. The movable frame 122 plays a load-bearing role for the second motor 10. Accordingly, the screw rod 11 is higher than the movable frame 122. The fixed plate 121 is mounted on the upper side of the movable frame 122. The first motor 6 and the cutting wheel 7 are both lower than the movable frame 122. When the movable frame 122 moves downward, the cutting wheel 7 first contacts the horizontally placed steel bars on the fixing mechanism.

[0035] In the above manner, the width of the slide plate 9 can be limited to be close to the width of the movable groove 123. The cooperation between the movable groove 123 and the slide plate 9 can improve the stability of the slide plate 9 during lateral movement. For example, the width of the slide plate 9 can be limited to be smaller than the width of the movable groove 123, and the difference between the two can be controlled within 0.2 mm to 1 mm.

[0036] In some embodiments, please refer to Figure 1 、 Figure 2 and Figure 3 The slide plate 9 is connected to a downwardly extending connecting plate 8, such that the lower edge of the connecting plate 8 is lower than the lower edge of the slide plate 9. The mounting plate 5 is connected to the connecting plate 8, such that the mounting plate 5 is lower than the slide plate 9. The output shaft of the first motor 6 is rotatably disposed through the mounting plate 5. When the mounting plate 5 is lower than the slide plate 9, the first motor 6 located on the mounting plate 5 is lower than the slide plate 9, and the cutting wheel 7 connected to the first motor 6 is also lower than the slide plate 9. Furthermore, the thickness direction of the mounting plate 5 is perpendicular to the thickness direction of the slide plate 9, so that the axial direction of the cutting wheel 7 is substantially aligned with the length direction of the horizontally placed steel bar, ensuring that the cutting wheel 7 can cut the steel bar.

[0037] In some embodiments, see Figure 1 and Figure 2 The vertical plate 4 is provided with a lifting slot 133 extending along the thickness of the vertical plate 4. The length of the lifting slot 133 also corresponds to the height of the lifting slot 133. The movable frame 122 is slidably disposed in the lifting slot 133 and is driven by the lifting assembly 13 to move along the lifting slot 133. In this embodiment, the cutting assembly and the fixing mechanism are located on the same side of the vertical plate 4, and the second motor 10 is located on the side of the vertical plate 4 facing away from the cutting assembly. This allows the second motor 10 to avoid the high-temperature debris generated during the steel bar cutting process.

[0038] In some embodiments, see Figure 2The lifting assembly 13 includes a top plate 131 and a telescopic member 132. The top plate 131 is connected to the top of the vertical plate 4. The top plate 131 provides a mounting base for the telescopic member 132. The telescopic member 132 is mounted on the bottom side of the top plate 131 and is connected to the movable frame 122. The telescopic member 132 can be in the form of an electric cylinder, an electric telescopic rod, etc. When the telescopic member 132 is an electric cylinder, the cylinder base of the electric cylinder is fixedly mounted on the bottom side of the top plate 131, and the cylinder rod of the electric cylinder is fixedly connected to the movable frame 122. In this embodiment, the telescopic member 132 and the second motor 10 are located on the same side of the vertical plate 4, so that the telescopic member 132 also avoids the high-temperature debris generated during the steel bar cutting process.

[0039] In some embodiments, see Figure 2 The vertical plate 4 is connected to a fixed frame 15, which is distributed along the horizontal plane. The fixed frame 15 is located on the side of the vertical plate 4 away from the cutting assembly. The fixed frame 15 and the top plate 131 provide a mounting base for the guide rod 14. The guide rod 14 is installed between the fixed frame 15 and the top plate 131. The bottom end of the guide rod 14 is connected to the fixed frame 15, and the top end of the guide rod 14 is connected to the top plate 131. The guide rod 14 is slidably inserted into the movable frame 122. When the telescopic member 132 causes the movable frame 122 to move in the height direction, the movable frame 122 also moves along the guide rod 14. At this time, the guide rod 14 guides the movement of the movable frame 122, which is beneficial to the smoothness and stability of the cutting assembly and the transverse movable assembly 12 when they move in the height direction.

[0040] In some embodiments, see Figure 2 The telescopic member 132 and the guide rod 14 are arranged on opposite sides of the second motor 10, which can further improve the smoothness and stability of the guide rod 14 when the movable frame 122 moves along the height direction.

[0041] In some embodiments, see Figure 1 The fixing mechanism includes a support frame 3, two placement frames 2, and two positioning frames 21. The support frame 3 is mounted on the platform 1 and has at least two first grooves on its upper side. The number of first grooves is equal to the number of steel bar flattening positions. Two placement frames 2 are mounted on the platform 1 and are located on opposite sides of the support frame 3. The placement frames 2 have at least two second grooves on their upper sides. The number of second grooves in a single placement frame 2 is equal to the number of steel bar flattening positions.

[0042] The two positioning frames 21 are rotatably connected to the two placement frames 2, respectively. The positioning frames 21 are provided with at least two third grooves. The number of third grooves in a single positioning frame 21 is equal to the number of rebar flattening positions. The positioning frames 21 can be rotated until they mate with the placement frames 2 and can maintain this mate. When the positioning frames 21 mate with the placement frames 2, the second and third grooves enclose a retaining groove. The rebar is sequentially placed in one retaining groove, then the first groove, and then the other retaining groove, and the rebar is retained in the retaining grooves. The retaining grooves and the first grooves together form the rebar flattening position.

[0043] The above definition defines that the positioning frame 21 is rotatably connected to the placement frame 2. In some embodiments, please refer to Figure 1 and Figure 3 One end of the length of the placement rack 2 is provided with a rear fixed plate 19, and the rear bottom plate is provided with a mounting groove 20 located on the upper side. The positioning rack 21 can be rotatably mounted in the mounting groove 20 of the rear fixed plate 19 through a pin.

[0044] For some embodiments of maintaining the positioning frame 21 and the placement frame 2 in a constant state of contact, please refer to Figure 1 The rotatable connection between the positioning frame 21 and the placement frame 2 is at the position of the rear fixed plate 19. The positioning frame 21 is provided with a block 24 at the end away from the rear fixed plate 19. The placement frame 2 is connected to a front fixed plate 22 at the end away from the rear fixed plate 19. The front fixed plate 22 is provided with a slot 23 on the upper side. The front fixed plate 22 is threadedly connected with a rotating rod 25. The threaded hole in which the rotating rod 25 is installed is connected to the slot 23. The rotating rod 25 can be tightened in the threaded hole to the extent of abutting against the block 24, and the block 24 can be pressed tightly against the slot 23, thereby realizing the functional limitation of the steel bar being limited in the limit groove.

[0045] In some embodiments, please refer to Figure 1 and Figure 3 The support frame 3 is a frame-like structure, enclosing a central groove 31 that extends through the thickness of the support frame 3. The platform 1 is provided with a storage groove 17. The storage groove 17 forms a first notch 171 on the vertical side of the platform 1 and a second notch 172 on the top side of the platform 1. The second notch 172 is in communication with the central groove 31. A storage box 18 is installed in the storage groove 17. High-temperature debris generated during the steel bar cutting process can fall into the storage box 18 along the central groove 31. The storage box 18 can be pulled out of the first notch 171 for easy cleaning by the user. Thus, the construction steel bar cutting and processing equipment of this embodiment achieves convenient cleaning of metal debris.
