Description

[0002] The materials used in the formwork of reinforced concrete frame components are composed of wooden formwork, seven-ply plywood, steel formwork, etc. The steel bars are processed into semi-finished products in the logistics processing plant and then tied on site. In addition to binding and overlapping, flash butt welding, arc welding, electroslag pressure welding and sleeve extrusion connection technologies have been applied and promoted for the horizontal and vertical connections of the steel bars. Bending equipment is used in the process of steel bar processing.

[0003] Precast concrete components refer to concrete parts that are processed and produced in a standardized and mechanized manner in a factory. The main components are concrete, steel bars, embedded parts, thermal insulation materials, etc. Since the components are mechanized in the factory, the quality and precision of the components are controllable and are less restricted by the environment. Precast steel bars are steel bars in components that are prefabricated on site or in a processing plant. Precast steel bars need to be bent to a specified shape before use.

[0004] However, most of the current prefabricated steel bar bending equipment is prone to force displacement when bending prefabricated steel bars, which will cause the bending points of each section of the prefabricated steel bar to be inconsistent, and it is difficult to control the distance of the prefabricated steel bar each time it is transported and moved, resulting in different lengths of the prefabricated steel bar each time it is bent, resulting in the shape of the prefabricated steel bar after bending not being standard.

[0029] Embodiment 1: A bending device for prefabricated frame components for construction, such as Figure 1-Figure 10As shown, it includes a support seat 1, a fixed support plate 2, a limiting plate 3, a clamping plate 4, a clamping mechanism and a bending mechanism. The support seat 1 is connected with a fixed support plate 2 by bolts, and the support seat 1 is connected with a limiting plate 3 by bolts. The fixed support plate 2 is fixedly connected to the limiting plate 3, and the fixed support plate 2 is slidably connected with the clamping plate 4. The clamping mechanism is arranged on the support seat 1, and the bending mechanism is arranged on the clamping mechanism.

[0030] The clamping mechanism includes a servo motor 51, a power shaft 52, a fixed rod 53, an extrusion spring 54, a fixed guide plate 55, a clamping rod 56, a compression spring 57, a fixed transverse rod 58, a fixed cam 59 and a fixed convex ring 510. The support seat 1 is connected to the servo motor 51 by bolts, and the top of the output shaft of the servo motor 51 is connected to the power shaft 52 by bolts. The power shaft 52 is rotatably connected to the support seat 1, and the lower part of the clamping plate 4 is slidably connected to the fixed rod 53, and a limiting hole is opened on the fixed rod 53. The fixing rod 53 and the clamping plate 4 are connected by a hook with an extrusion spring 54, and the extrusion spring 54 is sleeved on the fixing rod 53. A fixed guide plate 55 is connected to the top of the power shaft 52 by bolts, and a clamping rod 56 is slidably connected to the fixed guide plate 55. The end of the clamping rod 56 away from the power shaft 52 contacts the fixed rod 53, and a compression spring 57 is connected between the clamping rod 56 and the fixed guide plate 55 through a hook. A fixed transverse rod 58 is connected to the bottom of the fixed rod 53 by rivets, and a fixed cam 59 is connected to the upper part of the power shaft 52 by bolts.

The power shaft 52 is fixedly connected to the fixed convex ring 510, and the clamping rod 56 and the fixed convex ring 510 are located in the same horizontal plane.

[0031] The bending mechanism includes a sector gear 61, a rotating shaft 62, a rotating gear 63, a fixed plate 64, a bending rod 65 and a bending plate 66. The middle part of the power shaft 52 is connected to the sector gear 61 via a flat key, the supporting seat 1 is rotatably connected to the rotating shaft 62, the lower part of the rotating shaft 62 is connected to the rotating gear 63 via a flat key, the sector gear 61 will mesh with the rotating gear 63, the upper part of the rotating shaft 62 is connected to the fixing plate 64 via bolts, the fixing plate 64 is fixedly connected to the bending rod 65, and the upper part of the bending rod 65 is connected to the bending plate 66 via bolts.

[0032] First, the staff places the steel prefabricated part on the fixed support plate 2 so that the steel prefabricated part is located between the limit plate 3 and the bending plate 66. Then the staff starts the servo motor 51. The rotation of the output shaft of the servo motor 51 drives the power shaft 52 to rotate clockwise. The clockwise rotation of the power shaft 52 drives the fixed cam 59, the fixed convex ring 510 and the fan gear 61 to rotate clockwise. The fixed cam 59 contacts the fixed transverse rod 58. The clockwise rotation of the fixed cam 59 pushes the fixed transverse rod 58 away from the limit plate 3. The movement of the fixed transverse rod 58 will drive the fixed rod 53 to move horizontally, and the extrusion spring 54 will be compressed, so that the limit hole on the fixed rod 53 will align with the clamping rod 56. The movement of the fixed rod 53 will drive the clamping plate 4 to move in the direction close to the limit plate 3, and the clamping plate 4 will contact the prefabricated steel bar, so that the limit plate 3 and the clamping plate 4 clamp the prefabricated steel bar, and the clockwise rotation of the power shaft 52 will drive the fixed cam 59, the fixed convex ring 510 and the fan gear 61 to continue to rotate clockwise, and the fixed convex ring 510 will contact the prefabricated steel bar. The clamping rod 56 contacts the fixed convex ring 510, and the clockwise rotation of the fixed convex ring 510 will push the clamping rod 56 to move away from the power shaft 52. The clamping rod 56 will be stuck in the limiting hole on the fixed rod 53, so that the clamping rod 56 limits the fixed rod 53. The clockwise rotation of the power shaft 52 will drive the fixed cam 59, the fixed convex ring 510 and the fan gear 61 to continue to rotate clockwise. The fan gear 61 is meshed with the rotating gear 63. The clockwise rotation of the fan gear 61 will drive the rotating gear 63 to rotate counterclockwise, and the counterclockwise rotation of the rotating gear 63 will drive The rotating shaft 62 rotates counterclockwise, and the counterclockwise rotation of the rotating shaft 62 will drive the fixed plate 64 to swing away from the clamping plate 4. The swing of the fixed plate 64 will drive the bending rod 65 to swing away from the clamping plate 4. The swing of the bending rod 65 will drive the bending plate 66 to swing away from the clamping plate 4. The swing of the bending plate 66 will bend the prefabricated steel bar. In this way, the prefabricated steel bar is fixed and limited by the limiting plate 3 and the clamping plate 4, so that the prefabricated steel bar is more stable when bent, and the prefabricated steel bar is better bent.

[0033] Then the staff will adjust the servo motor 51 so that the output shaft of the servo motor 51 rotates counterclockwise. The counterclockwise rotation of the output shaft of the engine will drive the power shaft 52 to rotate counterclockwise. The counterclockwise rotation of the power shaft 52 will drive the fixed cam 59, the fixed convex ring 510 and the fan gear 61 to rotate counterclockwise. The clamping rod 56 will be out of contact with the fixed convex ring 510, and the compression spring 57 will be reset. The reset of the compression spring 57 will drive the clamping rod 56 to move and reset in the direction close to the power shaft 52. The limiting hole on the clamping rod 56 will be out of contact with the fixed rod 53, the fixed transverse rod 58 will be out of contact with the fixed cam 59, the extrusion spring 54 will be reset, and the reset of the extrusion spring 54 will drive the clamping plate 4 to reset in the direction away from the limiting plate 3, so that the clamping plate 4 is out of contact with the prefabricated steel bar. The reset of the clamping plate 4 will drive The fixing rod 53 moves horizontally to reset, and the reset of the fixing rod 53 will drive the fixed transverse rod 58 to move and reset in the direction close to the limit plate 3, the counterclockwise rotation of the sector gear 61 will drive the rotating gear 63 to rotate clockwise, and the clockwise rotation of the rotating gear 63 will drive the rotating shaft 62 to rotate clockwise, and the clockwise rotation of the rotating shaft 62 will drive the fixing plate 64 to swing and reset in the direction close to the clamping plate 4, and the reset of the fixing plate 64 will drive the bending rod 65 to swing and reset in the direction close to the clamping plate 4, and the reset of the bending rod 65 will drive the bending plate 66 to swing and reset in the direction close to the clamping plate 4, then the staff adjusts the prefabricated steel bar to the appropriate position, and repeats the above steps twice, so that the prefabricated steel bar is bent three times to form a mouth shape, thereby completing the bending of the prefabricated steel bar, and finally the staff takes away the bent prefabricated steel bar.

[0034] Embodiment 2: Based on embodiment 1, Figure 5-Figure 10 As shown, it also includes a conveying mechanism, which is arranged on the support base 1. The conveying mechanism includes a power motor 71, a rotating shaft 72, a conveying wheel 73 and a transmission gear 74. The support base 1 is connected to the power motor 71 by bolts, and two rotating shafts 72 are rotatably connected to the support base 1. The two rotating shafts 72 are symmetrically arranged, and the bottom end of one of the rotating shafts 72 is fixedly connected to the top end of the output shaft of the power motor 71. The top ends of the two rotating shafts 72 are connected to the conveying wheel 73 by bolts, and the lower parts of the two rotating shafts 72 are connected to the transmission gear 74 by flat keys, and the two transmission gears 74 are meshed.

[0035] After the bending plate 66 bends the prefabricated steel bar once and resets it, the staff starts the power motor 71, and the output shaft of the power motor 71 drives one of the rotating shafts 72 to rotate clockwise, and the clockwise rotation of one of the rotating shafts 72 drives one of the transmission gears 74 and the conveying wheel 73 to rotate clockwise, and the clockwise rotation of one of the transmission gears 74 drives the other transmission gear 74 to rotate counterclockwise, and the counterclockwise rotation of the other transmission gear 74 drives the other rotating shaft 72 to rotate counterclockwise, and the counterclockwise rotation of the other rotating shaft 72 drives The other conveying wheel 73 rotates counterclockwise, and the rotation of the two conveying wheels 73 will convey the prefabricated steel bars to move a suitable distance, so as to facilitate the bending of the steel bars again. When the prefabricated steel bars are bent, the staff will turn off the power motor 71. In this way, the conveying wheel 73 is driven by the power motor 71 to convey the prefabricated steel bars, so that the prefabricated steel bars can be conveyed and moved at a consistent distance each time, so that the bending point of the prefabricated steel bars is consistent each time, and the length of the prefabricated steel bars bent each time is the same, so that the shape of the bent prefabricated steel bars is more standard.

[0036] Embodiment 3: Based on embodiment 2, Figure 2 As shown, it also includes a limiting mechanism, which is arranged on the support seat 1. The limiting mechanism includes a vertical plate 81, a movable baffle 82, a vertical rod 83 and a movable plate 84. The support seat 1 is connected with the vertical plate 81 by bolts, and the upper part of the vertical plate 81 is slidably connected with the movable baffle 82, and the movable baffle 82 is connected with the vertical rod 83 by bolts. The upper part of the clamping plate 4 is connected with the movable plate 84 by bolts, and a limiting groove is opened on the movable plate 84, and the vertical rod 83 is located in the limiting groove on the movable plate 84.

[0037] When the staff places the steel prefabricated part on the fixed support plate 2, one end of the steel prefabricated part will contact the movable baffle 82, and the movable baffle 82 will limit the steel prefabricated part, so that the position of the steel prefabricated part placed each time is more accurate. When the clamping plate 4 moves in the direction close to the limiting plate 3, the clamping plate 4 will drive the movable plate 84 to move in the direction close to the limiting plate 3. The movement of the movable plate 84 will drive the vertical rod 83 to move along the limiting groove on the movable plate 84 in the direction close to the vertical plate 81. The movement of the vertical rod 83 will drive the movable baffle 82 to move in the direction away from the clamping plate 4, and the movable baffle 82 will be out of contact with the steel prefabricated part. When the clamping plate 4 moves and resets in the direction away from the limiting plate 3, the clamping plate 4 will drive the moving plate 84 to move and reset in the direction away from the limiting plate 3. The reset of the moving plate 84 will drive the vertical rod 83 to move and reset along the limiting groove on the moving plate 84 in the direction away from the vertical plate 81. The reset of the vertical rod 83 will drive the moving baffle 82 to reset in the direction close to the clamping plate 4. The moving baffle 82 will contact the prefabricated steel bar again, and the moving baffle 82 will limit the prefabricated steel bar again. In this way, the distance of the prefabricated steel bar conveying and moving each time can be further made consistent, thereby further making the length of the prefabricated steel bar bent each time the same.

[0038] Embodiment 4: Based on the embodiment 3, Figure 1 and Figure 2 As shown, a prefabricated part support plate 9 is also included. The support seat 1 is connected to the prefabricated part support plate 9 by bolts, and the prefabricated part support plate 9 is fixedly connected to the limiting plate 3.

[0039] The prefabricated part support plate 9 can support the bent part of the prefabricated steel bar, so that the prefabricated steel bar remains stable and not easily deformed during the bending process, thereby making the bent prefabricated steel bar better.
