[0007] Preferably, the positioning rod is inserted into one of the positioning holes on the upper surface of the limiting turntable, and the movable groove and the slider are of the same specification, both being square, and the slider can only move laterally within the sliding rod.
[0008] Preferably, a groove for limiting the reinforcing bars is provided at the center of the upper surface of the limiting block. Multiple sets of limiting blocks are provided, and the grooves on each set of limiting blocks have different specifications, which are used to limit reinforcing bars of different diameters.
[0009] Preferably, the limiting mechanism includes an installation groove at the center of the upper surface of the base, an insert block fixedly connected to the center of the bottom end of the installation groove, a through groove at the center of the insert block, a push rod at the center of the lower surface of the base, a rotating rod fixedly connected to the top of the push rod that rotates within the base, the top of the rotating rod rotating within the through groove, pull ropes fixedly connected to the tops of the left and right sides of the rotating rod, a movable block fixedly connected to the outside of the pull rope that slides within the through groove, a locking block fixedly connected to the outside of the movable block, a spring fixedly connected to the inside of the movable block, an installation block fixedly connected to the bottom end of the limiting block, a slot at the center of the lower surface of the installation block, and locking grooves on both sides inside the slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This rebar bending and forming device has an installation block at the bottom of the limiting block. When the installation block is inserted into the installation groove on the platform, the insert block in the installation groove is inserted into the slot on the installation block. At this time, the locking blocks on both sides of the slot can be locked into the locking slot on the slot, completing the installation of the limiting block at the center position of the top of the platform. At this time, the limiting block can be used in conjunction with the bending block to perform rebar bending work. When it is necessary to replace the limiting block with a different specification for rebar of different diameters, by rotating the push rod at the bottom of the platform, the push rod pulls the pull rope through the rotating rod to rewind.

[0013] 2. This rebar bending and forming device features a bending block at the top of a limiting turntable. When the limiting turntable rotates, the bending block rotates, bending the rebar within the limiting block. Multiple positioning holes are located at the top of the limiting turntable. By inserting a positioning rod from the bending block into the positioning hole on the limiting turntable, the bending block's position at the top of the turntable can be fixed. Simultaneously, by removing the positioning rod from the positioning hole on the limiting turntable, the bending block can drive a slider to slide on a sliding rod. By inserting the positioning rod at the bottom of the bending block into different positioning holes on the limiting turntable, the position of the bending block on the limiting turntable can be adjusted. This allows for different rebar bending requirements in conjunction with the limiting block, improving the flexibility and overall applicability of the rebar bending and forming device.

The device also includes an adjustment mechanism 4 and a limiting mechanism 5. The adjustment mechanism 4 is used to adjust the position of the bending block 3 at the top of the limiting turntable 2. The limiting mechanism 5 is used to replace the limiting block 6. When the drive motor 101 is started, it can drive the gear 102 to rotate. At this time, the gear 102 can push the toothed block 201 on the limiting turntable 2 and push the limiting turntable 2 to rotate as a whole. At this time, the bending block 3 at the top of the limiting turntable 2 can cooperate with the limiting block 6 to perform rapid bending of the rebar.
[0022] The center of the upper surface of the limiting block 6 is provided with a groove for limiting the reinforcing bars. There are multiple sets of limiting blocks 6, and the grooves on each set of limiting blocks 6 are of different specifications, which are used to limit reinforcing bars of different diameters.
[0023] The limiting mechanism 5 includes a mounting groove 501 at the center of the upper surface of the base 1.

At this time, the locking block 508 can be retracted into the insertion block 502. When the locking block 508 is not subjected to force, the spring 509 can push the locking block 508 to quickly extend out of the insertion block 502 through the movable block 507. When the mounting block 601 at the bottom of the limiting block 6 is inserted into the mounting groove 501, the insertion block 502 in the mounting groove 501 can be inserted into the slot 602 on the lower surface of the mounting block 601. At this time, the locking blocks 508 on both sides of the insertion block 502 can be locked into the slots 603 on the slot 602, thus fixing the position of the limiting block 6 at the top of the base 1.
