Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combination Figures 1 to 6 To illustrate this embodiment, this embodiment provides a steel bar bending machine, which includes a base plate 1, the base plate 1 is fixedly connected to a feeding platform 3 through a column 2, a feeding mechanism 4 is installed on the feeding platform 3, the feeding mechanism 4 includes a plurality of lower guide rails 41, an upper guide rail 42, a lower clamping block 43, an upper clamping block 44 and a lifting frame 45, the lower guide rail 41 is slidably connected to the feeding platform 3, the lower clamping block 43 is elastically slidably connected to the lower guide rail 41, the upper clamping block 44 is elastically slidably connected to the upper guide rail 42, the upper guide rail 42 is fixed on the lifting frame 45, a bending mechanism 5 is provided at the discharging end of the feeding platform 3, and a blocking mechanism 6 is provided on the side of the bending mechanism 5 away from the feeding platform 3.

[0024] In this example, the lower guide rail 41 is arranged at equal intervals along the width direction of the feeding platform 3, and the lower guide rail 41 is arranged one by one with the upper guide rail 42. The upper clamp block 44 and the lower clamp block 43 are provided with grooves on the opposite sides, so that the upper clamp block 44 and the lower clamp block 43 can clamp and fix the steel bars. After the clamped steel bars are abutted against the material blocking mechanism 6, the upper clamp block 44 and the lower clamp block 43 slide elastically along the upper guide rail 42 and the lower guide rail 41, so that the abutted steel bars no longer move, and the non-abutted steel bars continue to move until all the steel bars are aligned.

[0025] like Figure 3 , 4 As shown, a rack 46 is provided at the bottom of the lower guide rail 41, and a groove 31 corresponding to the rack 46 is provided on the feeding platform 3. A driving shaft 32 is movably connected to the bottom of the feeding platform 3, and the driving shaft 32 is movably connected to the bottom of the feeding platform 3.

The first motor 33 drives the driving shaft 32 to rotate, and the driving gear 34 is engaged with the rack 46 to drive the lower guide rail 41 to slide along the feeding platform 3.

[0026] like Figure 2 , 4As shown, the opposite sides of the upper guide rail 42 and the lower guide rail 41 are provided with sliding grooves 7, the upper clamping block 44 is slidably connected to the sliding grooves 7 on the upper guide rail 42, and the lower clamping block 43 is slidably connected to the sliding grooves 7 on the lower guide rail 41, and a light rod 8 is fixedly connected between the two ends of the sliding grooves 7 and the light rod 8 slides through the upper clamping block 44 or the lower clamping block 43, and the two end surfaces of the upper clamping block 44 and the lower clamping block 43 are connected to the end surfaces of the sliding grooves 7 by springs 9, so that the upper clamping block 44 and the lower clamping block 43 can elastically slide along the moving direction of the steel bar, and the spring 9 adopts a high elastic spring.

[0028] like Figure 2 As shown, a guide plate 10 is provided at the feed end of the feeding platform 3, and a guide groove 11 corresponding to the lower clamping block 43 is provided on the guide plate 10. Ear plates 12 are fixedly connected at both ends of the guide plate 10, and a pressure roller 13 is movably connected between the ear plates 12. The guide groove 11 can guide the steel bars, and cooperate with the pressure roller 13 to limit the upper and lower positions of the steel bars, so that the steel bars can accurately enter the groove on the top surface of the lower clamping block 43.

[0029] like Figure 5 As shown, the bending mechanism 5 includes a fixed pressure roller member 51 and a movable pressure roller member 52. The fixed pressure roller member 51 is fixed at the discharge end of the feeding platform 3, and an orientation bar 53 is provided below the fixed pressure roller member 51. The orientation bar 53 is provided with a positioning groove 54 corresponding to the lower clamping block 43. The orientation bar 53 and the fixed pressure roller member 51 limit the bending point of the steel bar, and the movable pressure roller member 52 is driven to rotate around the fixed pressure roller member 51 through the driving structure. The driving structure includes symmetrically arranged vertical frames 55, and a turntable 56 is movably connected to the two vertical frames 55. The two ends of the fixed pressure roller member 51 are fixedly connected to the eccentric position of the turntable 56. A slave gear 57 is fixedly connected to the turntable 56. A moving gear 58 is fixedly connected to the vertical frame 55. The two moving gears 58 are connected by a transmission rod. The moving gear 58 is connected by a second motor 59. The second motor 59 is a servo motor. The second motor 59 drives the moving gear 58 to rotate. The moving gear 58 meshes with the slave gear 57 to drive the slave gear 57 to rotate, thereby driving the turntable 56 to rotate. The movable pressure roller member 52 on the turntable 56 drives the steel bar to bend.

[0030] The fixed pressure roller member 51 and the movable pressure roller member 52 have the same structure, and both include a fixed rod, and a plurality of rollers are rotatably connected to the fixed rod. The rollers are arranged in a one-to-one correspondence with the lower clamping block 43.

[0031] like Figure 6 As shown, the material blocking mechanism 6 includes two symmetrically arranged slides 61, a slide seat 62 is slidably connected to the slide 61, an axle seat 63 is fixedly connected to the slide seat 62, a shaft rod 64 is movably connected between the two axle seats 63, a baffle 65 is fixedly connected to the shaft rod 64, one end of the shaft rod 64 is fixedly connected to a third motor 66, and the third motor 66 drives the baffle 65 to rotate, so as to achieve the purpose of abutting or not abutting the steel bar. A screw rod 67 is movably connected to the slide 61, one end of the screw rod 67 is fixedly connected to a handle 68, the screw rod 67 is threadedly connected to the slide seat 62, and a scale 69 is fixedly provided on the end surface of the slide 61 along the sliding direction of the slide seat 62, the screw rod 67 is rotated by the handle 68 to adjust the position of the axle seat 63, and then the position of the baffle 65 is adjusted, so as to achieve the limit of the bending length of the steel bar.

[0032] The working principle of the present invention is as follows: the steel bar is fed from the external conveying mechanism into the guide groove 11 on the guide plate, so that the steel bar is continuously pushed so as to enter between the upper clamp block 44 and the lower clamp block 43. When the steel bar is pushed close to the baffle plate 65, the pushing of the steel bar is stopped, and the first motor 33 rotates to drive the steel bar to continue to move until all the steel bars abut against the baffle plate 65. Then the second motor 59 drives the movable pressure roller 52 to rotate to bend the steel bar. After the bending is completed, the external output mechanism pulls the steel bar to pull the steel bar out, and the upper guide rail 42 is pressed down by the lifting frame 45, so that the upper clamp block 44 and the lower clamp block 43 are close to each other to clamp and fix the steel bar. The steel bar can be fed and bent in batches, the feeding is convenient, the bending efficiency is improved, and the uniformity of the steel bar bending can be ensured, thereby improving the steel bar bending quality.
