DETAILED DESCRIPTION

[0020] Embodiment 1, as Figure 1 to Figure 2 As shown, a metal bending device for construction engineering includes a workbench 1 installed on a mounting frame, a positioning shaft 9 is coaxially arranged on the top of the workbench 1, a bending column 2 is slidably penetrated through the eccentric position of the workbench 1, and two symmetrically arranged conveying rollers 3 are arranged on the side of the mounting frame away from the workbench 1; a driving component 4 is arranged at the bottom of the workbench 1, and an adjusting component 5 is connected to the bottom end of the bending column 2.

[0021] In this embodiment, one end of the steel bar is passed through between the two conveying rollers 3 in advance, and one end of the steel bar is placed between the positioning shaft 9 and the bending column 2. The initial placement position is placed manually. At this time, the workbench 1 is driven to rotate by the driving component 4, and the rotation of the workbench 1 drives the bending column 2 to rotate, and the steel bar is bent 90 degrees. After the steel bar is bent 90 degrees, the workbench 1 is driven by the driving component 4 to rotate in the opposite direction; while the workbench 1 rotates in the opposite direction, the bending column 2 is driven to descend through the cooperation of the driving component 4 and the adjusting component 5. At the same time, the driving component 4 can drive the steel bar to continue to move forward, so that the steel bar can be bent continuously.

[0022] like Figures 2 to 4 As shown, further, the adjustment component 5 includes a first adjustment plate 501, and a first slide groove 502 is opened on the side of the first adjustment plate 501 close to the bending column 2, and the end of the bending column 2 away from the workbench 1 is located in the first slide groove 502 and slides with it; the first slide groove 502 is smoothly connected by two groups of first arc grooves and two groups of first straight grooves, and a unidirectional rotating baffle 6 is arranged at the high point of the two groups of arc grooves.

[0023] The driving assembly 4 includes a forward and reverse motor 401, which is installed on a mounting frame. The output end of the forward and reverse motor 401 is connected to a rotating shaft 404 through a gear set 402. The rotating shaft 404 is rotatably connected to the mounting frame, and the rotating shaft 404 is fixedly connected to the bottom end of the workbench 1.

[0024] In this embodiment, the forward and reverse motor 401 drives the rotating shaft 404 to rotate counterclockwise through the gear set 402, and the counterclockwise rotation of the rotating shaft 404 drives the bending column 2 to rotate counterclockwise to bend the steel bar 90 degrees. The end of one of the conveying rollers 3 is connected to the motor. When the forward and reverse motor 401 drives the rotating shaft 404 to rotate counterclockwise, the motor does not run at this time, and the two conveying rollers 3 play a role in fixing the steel bar. After the bending column 2 rotates counterclockwise to bend the steel bar 90 degrees, the forward and reverse motor 401 drives the rotating shaft 404 to rotate clockwise. The clockwise rotation of the rotating shaft 404 drives the bending column 2 to rotate clockwise. At this time, the operation of the motor drives the conveying roller 3 to rotate, and the steel bar is synchronously fed; When the first adjustment plate 501 is viewed from a top view, it is a semicircular ring structure installed with the positioning shaft 9 as the axis. When the bending column 2 rotates counterclockwise, the bending column 2 moves from the high point of the first straight groove along the first straight groove at a high position, so that the height of the bending column 2 remains unchanged, and the steel bar is bent. When the steel bar is bent, one end of the bending column 2 passes through the baffle 6 that only rotates in one direction from the first straight groove to the first arc groove position. When the bending column 2 rotates clockwise, one end of the bending column 2 can fall along the position of the first arc groove. When one end of the bending column 2 moves from the high point position of the first arc groove to the low point position of the first arc groove, the bending column 2 is completely retracted into the interior of the workbench 1, and does not affect the synchronous feeding of the steel bar. The workbench 1 continues to move clockwise, so that one end of the bending column 2 slides along the first straight groove at the low point position, until it slides from the first straight groove to the high point position of another arc groove. At this time, the bending column 2 can also pass through the unidirectional rotating baffle 6, and the inside of the baffle 6 is connected to the first adjustment plate 501 through a torsion spring. The design of the baffle 6 enables the bending column 2 to make a U-shaped motion along the first slide groove 502. At this time, the bending column 2 moves upward and resets, and can continue to drive the rotating shaft 404 to rotate counterclockwise to continue bending the steel bars.

[0025] like Figures 5 to 7 As shown, in embodiment 2, the top end of the rotating shaft 404 is slidably connected with a first slide bar 8, the first slide bar 8 is coaxially fixedly connected to the bottom end of the workbench 1, and a second adjustment plate 7 is fixedly connected to the mounting frame, the second adjustment plate 7 is coaxially arranged with the first adjustment plate 501, a second slide groove 701 is opened on one side of the second adjustment plate 7, and the end of the first slide bar 8 away from the workbench 1 is located in the second slide groove 701 and slidably cooperates with it; the second slide groove 701 is smoothly connected by two groups of second arc grooves and two groups of second straight grooves, the number of baffles 6 is set to four, and the other two baffles 6 are respectively arranged at the high points of the two groups of second arc grooves.

[0026] In this embodiment, the counterclockwise rotation of the rotating shaft 404 drives the first slide bar 8 to rotate counterclockwise. In the bending path, one end of the first slide bar 8 also slides along the second straight groove located at a high position. After the first bending is completed, one end of the first slide bar 8 also makes a circular motion along the second slide groove 701, and the distance moved by one end of the baffle 6 in the second arc groove is equal to twice the distance moved by one end of the first slide bar 8 in the second arc groove, which means that when the rotating shaft 404 rotates clockwise, the height to which the bending column 2 is driven downward is equal to twice the height to which the first slide bar 8 drives the workbench 1 downward, so that when the workbench 1 and the bending column 2 move downward at the same time, the bending column 2 can still be retracted to the inside of the workbench 1; The downward movement of the workbench 1 can prevent the debris generated by the first bending from falling to the top of the workbench 1 when the steel bars are fed synchronously. When the steel bars are fed synchronously, the friction between the steel bar squeezing debris and the surface of the workbench 1 is reduced, thereby reducing the wear of the workbench 1.

[0027] like Figure 8 As shown, further, two semicircular slide plates 10 are symmetrically distributed on the top of the workbench 1, and a second transmission assembly is arranged inside the workbench 1.

[0028] In this embodiment, when the workbench 1 is descending, after the bending column 2 is completely retracted into the workbench 1, the two slides 10 are driven away from each other and tilted through the cooperation of the second transmission assembly to dump the waste on the surface of the slides 10.

[0029] like Figures 9 to 11 As shown, further, the second transmission assembly includes a guide rod 15, which passes through the first slide bar 8 and the workbench 1 in sequence and slides with them, one end of the guide rod 15 extends into the rotating shaft 404 and is fixedly connected thereto, and the other end of the guide rod 15 extends to the interior of the positioning shaft 9; the positioning shaft 9 extends into the interior of the workbench 1 and is rotatably connected thereto; a third slide groove 901 is provided inside the positioning shaft 9, and the third slide groove 901 is smoothly connected by a group of spiral grooves and a third straight groove; a slider 1501 is fixedly connected to the outside of the guide rod 15, and one end of the slider 1501 is arranged in the third slide groove 901 and slides with it.

[0030] A turntable 13 is fixedly connected to the outside of the positioning shaft 9, and a notch is provided on the turntable 13 to provide the bending column 2 with sufficient relative movement space. Two fourth slide grooves 1301 are penetrated through the top of the turntable 13, and the insides of the two fourth slide grooves 1301 are slidably connected with second slide bars 1302, and one end of the second slide bar 1302 is fixedly connected with a third slide bar 1303, and the third slide bar 1303 penetrates the limiting plate 14 and slidably cooperates with the fifth slide groove 1401, and the limiting plate 14 is fixedly connected to the inner wall of the workbench 1; the two third slide bars 1303 are respectively hinged to the bottom ends of the two slide plates 10; one end of the two limiting plates 14 is set to an arc surface.

[0031] In this embodiment, the rotating shaft 404 rotates clockwise to drive the workbench 1 to move downward. Before the bending column 2 tightens the inside of the workbench 1, when the workbench 1 moves downward, the slider 1501 is located in the third straight groove of the third slide groove 901 and slides. It should be particularly noted here that the bending column 2 sequentially penetrates the workbench 1 and one of the slide plates 10 and slides with it. When the workbench 1 and the bending column 2 are on the way down, the bending column 2 completely falls into the workbench 1, and the slider 1501 is located in the spiral groove of the third slide groove 901 and slides. At the same time, the rotation speeds of the positioning shaft 9 and the guide rod 15 change from the same to different. The rotation of the positioning shaft 9 drives the turntable 13 to rotate. The rotation of the turntable 13 drives the second slide bar 1302 to slide in the fourth slide groove 1301, so that the two symmetrically arranged second slide bars 1302 move in the directions away from each other. The movement of the second slide bar 1302 drives the slide plate 10 hinged thereto to move. Since one end of the limiting plate 14 is set to an arc surface, the slide plate 10 tilts after the horizontal movement, and the waste remaining on the surface of the slide plate 10 is dumped, and it is reset after the dumping is completed.

[0032] like Fig.12 As shown, further, the bottom ends of the two slide plates 10 that are close to each other are slidably connected with a second collecting groove 16 , and the second collecting groove 16 is connected to the slide plate 10 through a spring 17 .

[0033] In this embodiment, when the two slides 10 move away from each other, the two second collecting grooves 16 located at the bottom of the slide 10 move towards each other under the action of the spring 17, so that one side of the two second collecting grooves 16 can fit together and extend out, preventing waste from falling into the workbench 1 along the gap between the two slides 10; when the two slides 10 are reset, the two second collecting grooves 16 squeeze each other to overcome the action of the spring 17 and are stored at the bottom of the slide 10.

[0034] like Figure 7 As shown, further, a first collecting groove 12 in an annular shape is arranged in the mounting frame, and a cleaning brush 11 in an annular shape is installed inside the first collecting groove 12 .

[0035] In this embodiment, the two slide plates 10 move away from each other and then tilt, so as to contact with the cleaning brush 11. The slide plates 10 tilt away from each other and then rotate, thereby cleaning the waste on the surface of the slide plates 10.

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
