[0004] The bending device in the aforementioned patent still has some shortcomings. In actual use, most existing automatic bending devices have poor limiting of the bending of steel bars, and only use simple baffles for limiting. This can cause the steel bars to rebound easily during the bending process, which poses certain production risks and is inconvenient for users. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic bending device that solves the problem that most existing automatic bending devices have poor limiting capabilities when bending steel bars, relying only on simple baffles for limiting, which can lead to the steel bars easily rebounding during the bending process, posing certain production risks and making them inconvenient for users.

[0006] This utility model provides the following technical solution: an automatic bending device, including a bending worktable, with support legs evenly arranged around the bottom of the bending worktable, two limiting contact plates symmetrically arranged at the top of the bending worktable, a limiting plate arranged at the end of the limiting contact plate, and a bending limiting component arranged on the bending worktable.

[0007] The bending limiting assembly includes a rotating slot at the top of the bending worktable, a transmission insertion hole in the middle of the rotating slot, a servo motor at the bottom of the bending worktable, and a drive shaft connecting the outer side of the servo motor to the bending worktable. A bending rotating disk is housed within the rotating slot, and the top end of the drive shaft passes through the transmission insertion hole and is fixedly connected to the middle of the bottom end of the bending rotating disk. A limiting slot is located at the top of the bending rotating disk, and a bending abutment post is vertically arranged on the side of the top of the bending rotating disk. A support connecting frame is located on the side of the rotating slot, and a connecting cylinder is located at the end of the support connecting frame. Two adjusting screw holes are symmetrically arranged on both sides of the inner wall of the connecting cylinder, and two abutment connecting blocks are symmetrically arranged at the bottom of the connecting cylinder.

[0010] Preferred technical solution three: The gap formed between the two limiting contact plates is on the same straight line as the central axis of the limiting plate.

[0012] Preferred technical solution four: The sidewall of the abutting connecting block is in an arc shape that matches the connecting insert.

[0013] This solution allows the contacting block to be better adjusted within the connecting sleeve.

[0014] Preferred technical solution five: A limiting gap is left between the two abutting support plates.

[0023] Please see Figure 1-4 ,

[0024] Example 1: An automatic bending device includes a bending worktable 1, with support legs 2 evenly arranged around the bottom of the bending worktable 1, two limiting contact plates 3 symmetrically arranged at the top of the bending worktable 1, and limiting clamping plates 4 arranged at the ends of the limiting contact plates 3, and a bending limiting component 5 arranged on the bending worktable 1.

[0025] The bending limiting component 5 includes a rotating slot 501 at the top of the bending worktable 1. A transmission insertion hole 502 is provided in the middle of the rotating slot 501. A servo motor 503 is provided at the bottom of the bending worktable 1. The outer side of the servo motor 503 is connected to the bending worktable 1 through a drive shaft 504. A bending rotating disk 505 is provided inside the rotating slot 501. The top end of the drive shaft 504 passes through the transmission insertion hole 502 and is fixedly connected to the middle of the bottom end of the bending rotating disk 505. A limiting slot 506 is provided at the top of the bending rotating disk 505. A bending abutment post 507 is vertically provided on the side of the top of the bending rotating disk 505. A support connecting frame 508 is provided on the side of the rotating slot 501.

[0026] The end of the support connecting frame 508 is provided with a connecting tube 509. Two adjusting screw holes 510 are symmetrically opened on both sides of the inner wall of the connecting tube 509. Two abutting connecting blocks 511 are symmetrically arranged at the bottom of the connecting tube 509. Abutting support plate 512 is fixed at the bottom of each abutting connecting block 511. An adjusting screw 513 is inserted into the adjusting screw hole 510. The end of the adjusting screw 513 is rotatably connected to the side of the abutting connecting block 511. The bottom ends of the two abutting support plates 512 are inserted into the limiting slot 506.

[0027] Example 2: The difference between this example and Example 1 is that the gap formed between the two limiting contact plates 3 and the central axis of the limiting plate 4 are on the same straight line.

[0028] This allows the steel bars to be bent to be positioned more straight by the limiting contact plates 3 and the limiting clamping plate 4.

[0029] Example 3: The difference between this example and Example 1 is that the side wall of the contacting connecting block 511 is in an arc shape that matches the connecting insert 509.

[0030] This allows the contact block 511 to be better adjusted within the connecting sleeve 509.

[0031] Example 4: The difference between this example and Example 1 is that a limiting gap is left between the two abutting support plates 512.

[0032] This allows the contact support plate 512 to limit and stabilize the bent steel bars that pass through the gaps between them.

[0033] In this embodiment, since most existing automatic bending devices have poor limiting of the reinforcing bars to be bent in actual use, and only use simple baffles for limiting, the reinforcing bars are prone to rebound during the bending process, which poses certain production risks and is inconvenient for users.

[0034] In summary, during specific implementation, when a user needs to bend a steel bar, the user first needs to place the steel bar between two limiting contact plates 3, so that the end of the steel bar passes through the limiting clamp plate 4 and extends to the two contact support plates 512 in the bending limiting assembly 5. Since the top of the contact support plate 512 is inserted into the connecting tube 509 through the contact connecting block 511, and the distance of the contact connecting block 511 in the connecting tube 509 is adjustable, the user can rotate the adjusting screw 513 inserted in the adjusting screw hole 510 to shorten the distance between the two contact connecting blocks 511, thereby reducing the gap between the two contact support plates 512, so as to adapt to the bending of steel bars of more different diameters and improve its flexible application range. After the steel bar is limited by the contact of the two contact support plates 512.

[0035] The user starts the servo motor 503 by connecting it to power, which drives the bending turntable 505 inserted in the rotating slot 501 to rotate via the drive shaft 504. A bending abutment post 507 is vertically arranged on the side of the top of the bending turntable 505. The bending abutment post 507 can abut against the steel bar that is limited by the abutment support plate 512 and bend it to the processing requirements. Through the joint limitation of the limiting abutment plate 3, the limiting clamping plate 4 and the abutment support plate 512, the steel bar can be more stable during bending, effectively avoiding the steel bar rebounding during bending and injuring the operator, improving the safety factor and making it more convenient for the user.
