[0002] Steel bars are an indispensable material in various building structures. In order to facilitate the production and transportation of steel bars, they are generally in a straight main body shape. However, during the construction process, due to different building structures, steel bars of different lengths and curvatures are required. Therefore, the steel bars need to be cut and bent by bending and cutting machines.
[0003] The bending and cutting machine in the prior art includes a device that can bend and cut steel bars at the same time. The bending and cutting machine mainly includes a bending device and a cutting device. When the cutting device cuts the steel bars, the bending device bends the steel bars at the same time, which speeds up the processing efficiency of the steel bars.
[0004] However, since the cutting device cuts the steel bar, the cut point of the steel bar is in a semi-broken state. At this time, the bending device bends the steel bar, and the steel bar will be in an uneven force state due to the force applied by the bending device, which may easily cause the semi-broken steel bar at the cut point to crack, and then easily cause the incompletely bent steel bar to detach from the bending device, thereby increasing the scrap rate of the steel bar.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-6 , the utility model is described in further detail.
[0033] A construction steel bar bending and cutting machine 22, referring to Figure 1 and Figure 2 , including a base 1, and a cutting mechanism 2, a pressing mechanism 3 and a bending mechanism 4 installed on the base 1.
[0034] The base 1 in this embodiment is placed horizontally, and four universal wheels 11 are arranged below the base 1 to facilitate the transportation of the device by the staff. A half-edge protective cover 13 is arranged above the base 1 to prevent its internal parts from being damaged as much as possible.
[0035] The pressing mechanism 3 includes a vertical plate 31 , a first pressing member 32 and a second pressing member 33 .
[0036] The vertical plate 31 is arranged in a vertical direction on the upper end surface of the base 1. The vertical plate 31 in this embodiment is integrally formed with the base 1. The first clamping member 32 and the second clamping member 33 have the same structure. The first clamping member 32 and the second clamping member 33 are both installed on the same end surface of the vertical plate 31 and are located on the same horizontal plane.
[0037] Reference Figure 3 and Figure 4The first clamping member 32 includes a first half ring 321 and a second half ring 322. The first half ring 321 is fixedly mounted on the vertical plate 31, and the second half ring 322 is slidably mounted on the vertical plate 31. The second half ring 322 is located above the first half ring 321, and the moving direction of the second half ring 322 is arranged along the vertical direction; similarly, the first half ring 321 and the second half ring 322 in the second clamping member 33 have the same structure and layout as those in the first clamping member 32; at the same time, a driving member 34 for driving the second half ring 322 to move in a direction close to or away from the first half is also provided on the vertical plate 31.
[0038] Secondly, refer to Figure 2 The cutting mechanism 2 in this embodiment includes a support 21 and a cutting machine 22 (refer to Figure 6 ), the support 21 is located on the upper end surface of the base 1, and the support 21 is located on the side of the vertical plate 31 away from the clamping mechanism 3, and a slide rail 12 is arranged between the support 21 and the base 1, and the support 21 can slide in the direction close to or away from the vertical plate 31 through the slide rail 12; the cutting machine 22 is fixedly installed on the upper end surface of the support 21. The cutting machine 22 in this embodiment is the prior art and will not be described in detail here; in addition, it should be noted that a through groove 312 is provided on the vertical plate 31 for the cutting machine 22 head to pass through, and the through groove 312 is arranged in the vertical direction and is located in the middle position of the first clamping member 32 and the second clamping member 33.
[0039] In addition, refer to Figure 2 and Figure 6 The bending mechanism 4 in this embodiment is installed on the vertical plate 31 and is located on the side of the second clamping member 33 relatively away from the first clamping member 32. A linkage member 5 is provided between the bending mechanism 4 and the cutting mechanism 2. When the bending mechanism 4 bends the steel bar, the bending mechanism 4 drives the support 21 in the cutting mechanism 2 to move in the direction close to the vertical plate 31 through the linkage member 5 until the blade head of the cutting machine 22 passes through the through slot 312 and cuts the steel bar.
[0040] When the steel bars need to be bent, the steel bars are first placed on the two first half rings 321 in the clamping mechanism 3, and then the two first half rings 321 are driven by the driving member 34 to move in a direction close to the second half ring 322 until the first half ring 321 is pressed against the surface of the steel bars, and then the steel bars are bent by starting the bending mechanism 4. At the same time, the bending mechanism 4 drives the support 21 in the cutting mechanism 2 to move in a direction close to the vertical plate 31 through the linkage member 5 until the blade of the cutting machine 22 passes through the through groove 312 and cuts the steel bars, thereby completing the processing of the steel bars.
[0041] In the above process, since the first clamping member 32 and the second clamping member 33 respectively tighten the steel bar on both sides of the cutting point of the steel bar, when the steel bar is subjected to the pressure of the bending mechanism 4, the second clamping member 33 can also exert an opposite supporting force on the steel bar, so that the steel bar is in a relatively uniform force state, thereby avoiding the steel bar from cracking at the cutting point as much as possible. At the same time, the clamping member in the device includes a first half ring 321 and a second half ring 322. The two half rings can surround and tighten the steel bar, and the steel bar is not easy to detach from the bending mechanism 4. While reducing the scrap rate of the steel bar, it can also avoid the detachment of the steel bar to threaten the staff, thereby reducing the safety hazard of the device.
[0042] In order to further enhance the fixing effect between the clamping mechanism 3 and the steel bar, anti-slip pads 6 are provided on the inner walls of the first half ring 321 and the second half ring 322, which increase the friction between the steel bar and the clamping mechanism 3, thereby avoiding lateral movement of the steel bar when being bent, thereby ensuring that the bending mechanism 4 can bend the steel bar to the required curvature.

Two slide grooves 311 are provided on the vertical plate 31. The two slide grooves 311 correspond to the two sliders 341 one by one. The slide grooves 311 are located above the first half rings 321 and are arranged in the vertical direction. The sliders 341 are located in the slide grooves 311. A connecting rod 343 is provided between the two sliders 341. The connecting rod 343 is arranged in the horizontal direction. The hydraulic press 342 is installed on the vertical plate 31, and the output shaft of the hydraulic press 342 is connected to the connecting rod 343.
[0045] When the steel bars need to be tightened, the hydraulic press 342 is started, and the output shaft of the hydraulic press 342 is extended, driving the connecting rod 343 to move downward, thereby driving the two sliders 341 to move in a direction close to the first half ring 321, thereby driving the second half ring 322 to move in a direction close to the first half ring 321, until the first half ring 321 is pressed against the surface of the steel bars.
[0046] Reference Figure 2 , Figure 5 and Figure 6 The bending mechanism 4 includes a turntable 41 and a bending motor 42 .
[0047] The turntable 41 in this embodiment is rotatably mounted on the vertical plate 31 and is on the same plane as the first clamping member 32 and the second clamping member 33.

A stop block 411 is coaxially fixedly connected to the end surface of the turntable 41 facing away from the vertical plate 31. A bending block 413 is also provided on the turntable 41, and the bending block 413 and the stop block are on the same horizontal plane.
[0048] Among them, the stop block 411 and the bending block 413 are both set to be main-body-shaped, and the highest point on the peripheral wall of the stop block 411 is at the same height as the lowest point on the inner wall of the first semi-ring 321, so that the steel bar can be placed relatively horizontally; the bending block 413 is located obliquely above or below the stop block 411, and the height difference between the stop block 411 and the bending block 413 is greater than the diameter of the steel bar.
[0049] In addition, a connecting piece 43 is provided between the bending block 413 and the turntable 41, and the bending block 413 can be detachably connected to the turntable 41 through the connecting piece 43 to facilitate the subsequent replacement of the bending block 413, while trying to avoid the situation where the entire turntable 41 needs to be replaced due to damage to the bending block 413, thereby reducing the maintenance cost of the equipment.
[0050] The connecting piece 43 in the present embodiment is a screw, and a first screw hole 4131 is provided on the bending block 413, and a second screw hole 414 is provided on the turntable 41, and the first screw hole 4131 is communicated with the second screw hole 414. It should be noted that a plurality of second screw holes 414 are provided in the present embodiment, and the plurality of second screw holes 414 are evenly spaced around the axis of the turntable 41. The position of the bending block 413 can be adjusted according to the required bending degree of the steel bar, so that the rotation angle of the bending motor 42 can be kept at a constant value, which greatly simplifies the control system structure, thereby avoiding the use of high-precision motors as much as possible, reducing the cost of the bending motor 42, and thus reducing the manufacturing cost of the entire equipment.

[0053] When the bending motor 42 rotates forward, it drives the first bevel gear 51 to rotate, thereby driving the spur gear 53 to rotate through the second bevel gear 52, and then drives the support 21 to move in the direction close to the vertical plate 31 through the rack 54, thereby driving the blade of the cutting machine 22 to move in the direction close to the steel bar. Conversely, the bending motor 42 reverses and the blade of the cutting machine 22 moves in the direction away from the steel bar.
