[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In this embodiment, an automatic shearing and bending machine for steel bar processing includes a base 1, and a shearing and bending processing mechanism is arranged inside the base 1.

[0024] In this embodiment, the shearing and bending processing mechanism includes a toothed plate 2 fixedly connected to the inside of the base 1, and the base 1 is internally movably connected with two shift racks 3. The shift racks 3 are internally rotatably connected with a driving gear 5 and a driven gear 21 meshing with the toothed plate 2. The number of the driving gear 5 and the number of the driven gear 21 in the shift rack 3 are both two.

[0025] Among them, a driving member 4 for driving the driving gear 5 to rotate is arranged inside the shift frame 3, so that the driving member 4 can be used to drive the driving gear 5 to rotate, so that the shift frame 3 can move inside the base 1 as the driving gear 5 rotates by utilizing the meshing of the driving gear 5 and the toothed plate 2.

[0026] In this embodiment, the tops of the two shift racks 3 are respectively fixedly connected with a first fixed block 7 and a second fixed block 22, and the opposite sides of the first fixed block 7 and the second fixed block 22 are fixedly connected with two mounting plates 6, and the opposite sides of the front and rear mounting plates 6 are rotatably connected with a gear roller 8, and the first fixed block 7 and the second fixed block 22 are internally provided with a driving component for driving the gear roller 8 to rotate.

[0027] Among them, the driving component includes a lifting rack 9 movably connected between two mounting plates 6 and meshing with the gear roller 8. The first fixed block 7 and the second fixed block 22 are both fixedly connected with a bending cylinder 10. The output end of the bending cylinder 10 is fixedly connected with a connecting block 11, and the connecting block 11 is fixedly connected to the lifting rack 9, so that the bending cylinder 10 can use the connecting block 11 to drive the lifting rack 9 to move up and down, thereby causing the lifting rack 9 to drive the gear roller 8 to rotate.

[0028] Among them, the connecting block 11 is Z-shaped, and the opposite sides of the first fixed block 7 and the second fixed block 22 are provided with movable grooves 701 corresponding to the position of the connecting block 11, so that the connecting block 11 can move in the first fixed block 7 and the second fixed block 22 by utilizing the movable grooves 701. The side of the lifting rack 9 away from the gear roller 8 is fixedly connected to the limiting block 901, and the opposite sides of the first fixed block 7 and the second fixed block 22 are provided with limiting grooves 702 that are slidably adapted to the limiting block 901, so that the cooperation between the limiting block 901 and the limiting grooves 702 can be used to improve the activity stability of the lifting rack 9.

[0029] In this embodiment, a positioning cylinder 12 is fixedly connected to the front of the first fixed block 7, and a steel bar body 18 is movably connected inside the positioning cylinder 12. A center pin 15 and a driving pin 17 are fixedly connected to the front of the gear roller 8. The center pin 15 is coaxial with the gear roller 8. A guide groove 601 that is slidably matched with the driving pin 17 is provided inside the mounting plate 6, so that the driving pin 17 can press the steel bar body 18 to rotate around the center pin 15 as the gear roller 8 rotates, thereby realizing bending processing.

[0030] Among them, a positioning pin 16 corresponding to the position of the driving pin 17 is fixedly connected to the front of the mounting plate 6.

[0031] Among them, the cutting assembly includes a cutting cylinder 13 fixedly connected to the front side of the first fixed block 7, and the output end of the cutting cylinder 13 is fixedly connected with a cutting knife 14, so that the cutting knife 14 can cut the steel bar body 18 as the cutting cylinder 13 runs; the interior of the mounting plate 6 is fixedly connected with a pushing cylinder 19, and the output end of the pushing cylinder 19 is fixedly connected with a pushing plate 20, so that the product after cutting and bending can be pushed out by the movement of the pushing plate 20.

[0032] The beneficial effects of the above embodiments are:

[0033] The automatic shearing and bending machine for steel bar processing can flexibly adjust the positions of the two shifting frames 3 by rotating the driving gear 5 and the driven gear 21 on the tooth plate 2, so that the steel bar bodies 18 of different sizes can be cut according to the needs, and the shifting frames 3 and the steel bar bodies 18 can be moved forward at the same speed during the cutting and bending process, so as to facilitate the continuous feeding of the steel bar bodies 18 during the cutting and bending operations, thereby preventing the machine from stopping during cutting and bending to reduce the production and processing efficiency;

[0034] In addition, after the cutting and bending of the steel bar body 18 is completed, the push cylinder 19 can be operated to drive the push plate 20 to move, and the push plate 20 can push out the processed product, so as to make the product removal operation easier and further improve production efficiency.

[0035] The working principle of the above embodiment is:

[0036] The automatic shearing and bending machine for steel bar processing first needs to pass the steel bar body 18 through the positioning cylinder 12, and under the action of the external feeding mechanism, the steel bar body 18 moves to the right along the base 1. During this process, the driving member 4 can be operated to rotate the driving gear 5 on the tooth plate 2 to adjust the position of the shift frame 3, so as to facilitate cutting of steel bar bodies 18 of different sizes according to needs, and after the steel bar body 18 moves to the second fixed block 22, the two shift frames 3 can move to the right at the same speed as the steel bar body 18;

[0037] In this process, the cutting blade 14 can cut the steel bar body 18 as the cutting cylinder 13 operates, and the driving pin 17 can press the steel bar body 18 to rotate around the center pin 15 as the gear roller 8 rotates, thereby cooperating with the positioning pin 16 to achieve the bending of the steel bar body 18, so as to continue feeding when the steel bar body 18 is cut and bent, thereby preventing the machine from stopping during cutting and bending, causing a decrease in production and processing efficiency;

[0038] After the steel bar body 18 is cut and bent, the push cylinder 19 can be operated to drive the push plate 20 to move, and the push plate 20 can push out the processed product, so as to make the product removal operation easier and further improve the production efficiency.
