Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel bar processing, in particular to a hydraulic double-head steel bar bending machine. Background Art
[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners, including plain round steel bars, ribbed steel bars, and twisted steel bars. Rebar for reinforced concrete refers to straight bars or coiled steel used for reinforced concrete reinforcement. Its appearance is divided into plain round steel bars and deformed steel bars, and the delivery status is straight bars and coiled bars. Plain round steel bars are actually small round steel bars and coiled bars of ordinary low-carbon steel. Deformed steel bars are steel bars with ribs on the surface, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The appearance of the transverse ribs is spiral, herringbone, and crescent. It is expressed in millimeters of nominal diameter. The nominal diameter of deformed steel bars is equivalent to the nominal diameter of plain round steel bars with equal cross-section. The nominal diameter of steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm.
[0003] In the existing technology, traditional hydraulic double-head rebar bending machines usually have a relatively simple bending angle and direction for the rebar when bending rebar. Since traditional hydraulic double-head rebar bending machines have fewer bending angles and directions, construction workers cannot flexibly adjust them according to specific construction requirements, resulting in some special structures or complex designs. Additional work is required to adapt to the limitations of the equipment, thereby increasing the difficulty and complexity of construction. When the bending function of the equipment is limited, workers may need to manually adjust the position and posture of the rebar to adapt to the processing capacity of the equipment, which not only increases the labor intensity of the workers, but may also lead to reduced work efficiency.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1 - Figure 4 The technical solution of the hydraulic double-head steel bar bending machine provided by this utility model is:
[0025] In the embodiment of the present invention, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , comprising a box body 1, two mounting frames 2 are installed inside the box body 1, and a bending component 3 is installed on the outer wall of each mounting frame 2, and the bending component 3 includes a first mounting block 301 mounted on the inner top wall of the mounting frame 2, one end of the first mounting block 301 is connected to a hydraulic rod 302, and one end of the hydraulic rod 302 is connected to a telescopic rod 307, and a second mounting block 303 is also installed on one end of the inner wall of the mounting frame 2, and one end of the second mounting block 303 is rotatably connected to a third mounting block 304, and one end of the third mounting block 304 is connected to a first connecting rod 305, and a fourth mounting block 306 is installed on the outer wall of one side of the first connecting rod 305, and one end of the first connecting rod 305 away from the third mounting block 304 is connected It is connected to a second connecting rod 308, one end of the second connecting rod 308 is connected to the first rotating shaft 309, the outer wall of the first rotating shaft 309 is connected to the sleeve 310, the outer walls on both sides of the sleeve 310 are connected to the second rotating shaft 311, the interior of the sleeve 310 is connected to the support rod 4, one end of the support rod 4 is connected to the first universal joint 312, one end of the first universal joint 312 is connected to the second universal joint 313, one end of the second universal joint 313 is connected to the third connecting rod 314, one end of the third connecting rod 314 is connected to the fourth connecting rod 315, the end of the fourth connecting rod 315 away from the third connecting rod 314 is connected to the third universal joint 316, and one end of the third universal joint 316 is connected to the fourth universal joint 317.
[0026] It should be noted that the rotational connection between the two second rotating shafts 311 and the mounting frame 2 ensures the stability of the sleeve 310 and the support rod 4 inside the box 1 and the integrity of the bending assembly 3 during operation.
[0027] See Figure 4 A clamping assembly 5 is installed at the bottom end of the support rod 4. The clamping assembly 5 includes a hydraulic cylinder 501 installed at the bottom end of the support rod 4. Two clamping claws 502 are installed at the bottom end of the hydraulic cylinder 501. The two clamping claws 502 are each provided with a slot on the opposite side.
[0028] It should be noted that the clamping assembly 5 is used to firmly clamp the steel bars, thereby ensuring the stability of the equipment during operation and reducing processing errors caused by sliding of the steel bars.
[0029] See Figure 1Two supporting legs 6 are respectively installed on the outer walls of both sides of the box body 1, and the bottom ends of the two supporting legs 6 are connected to the bottom plate 7. A control panel 8 is installed on the outer wall of one side of the box body 1. The outer wall of the control panel 8 is installed with a display screen and multiple control buttons. The control panel 8 is electrically connected to the bending component 3 and the clamping component 5.
[0030] It should be noted that the support legs 6 provide additional support points for the box 1, making the entire device more stable during operation and preventing the device from shifting or tipping over due to vibration or external force. The bottom plate 7 is fixed with screws to make installation and disassembly of the device more convenient.
[0031] See Figure 4 The shapes of the two grooves are adapted to each other, and the inner walls of the grooves are paved with anti-slip textures.
[0032] It should be noted that the anti-slip pattern can increase the friction between the clamping jaws 502 and the steel bar, ensuring that the steel bar does not slide during the clamping process.
[0033] Working principle: By starting the control panel 8, the first mounting block 301 drives the hydraulic rod 302 to be lifted upward. When the hydraulic rod 302 is lifted upward, the telescopic rod 307 is simultaneously retracted toward the inside of the hydraulic rod 302, thereby driving the fourth mounting block 306 rotatably connected to the telescopic rod 307 to drive the first connecting rod 305 to be lifted upward along with the hydraulic rod 302. When the first connecting rod 305 is lifted, it drives the second connecting rod 308 rotatably connected to the first connecting rod 305. At the same time, because the second connecting rod 308, the first rotating shaft 309, and the sleeve 310 are rotatably connected, when the sleeve 310 drives the support rod 4 to be lifted, the first universal joint fixed to the top of the support rod 4 is The rotational connection between the joint 312 and the second universal joint 313 can allow the support rod 4 to be lifted upward along with the hydraulic rod 302. According to the rotation of the fourth universal joint 317, the support rod 4 can drive the clamping assembly 5 to rotate synchronously. Through the rotational connection of the fourth universal joint 317 and the third universal joint 316, the rotational connection of the fourth connecting rod 315 and the third connecting rod 314, and the rotational connection of the second universal joint 313 and the first universal joint 312, the two bending assemblies 3 can be deflected and lifted at different angles, and the two clamping claws 502 installed at the bottom end of the hydraulic cylinder 501 are responsible for firmly clamping the steel bars, ensuring the stability of the bending assembly 3 when bending the steel bars.
