Technical Field
[0001] The utility model relates to the technical field of cutting equipment, in particular to a steel bar cutting machine for building construction. Background Technique
[0002] As the skeleton of concrete, steel bars form reinforced concrete and become the main materials with a wide application area and large quantity in building structures. Before pouring concrete, the steel bars must be made into a skeleton of a certain specification and form and incorporated into the formwork. To make the steel bar skeleton, the steel bars need to be strengthened, stretched, straightened, cut, bent, connected and other processed, and finally tied into shape.
[0003] During the use of the existing steel bar cutting machine for building construction, the steel bars cannot be limited in position. When the steel bars enter the inner wall of the equipment for cutting, the cutting of the steel bars is offset, reducing the cutting quality. At the same time, during the cutting process of the equipment, the cutting of the steel bars cannot be adjusted according to the required length of the personnel, resulting in limitations of the equipment. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a steel bar cutting machine for building construction, which has the advantages of limiting the position of the steel bars and adjusting the length of the steel bars, and solves the problems raised in the above background technique.

[0022] In the above structure, by installing the placement plate 4, the steel bar is placed by using the placement plate 4, so that the steel bar enters the inner wall of the equipment for cutting.
[0023] In a preferred implementation mode: the output end of the switch 2 is electrically connected to the input end of the motor 18, the number of the fixed plates 3 is two, and the two fixed plates 3 are respectively located on the tops of the rotating wheel 20 and the driven wheel 21.
[0024] In the above structure, by manipulating the switch 2, the driving wheel 20 is driven to rotate by the motor 18. The driving wheel 20 drives the driven wheel 21 to rotate through the belt 19. The steel bar is located at the center of the two fixed plates 3, so that the two fixed plates 3 drive the steel bar to move into the inner wall of the machine body 1 during rotation, avoiding bending of the steel bar during cutting.
[0025] In a preferred embodiment: a cylinder 14 is fixedly installed at the top of the machine body 1, and the output end of the switch 2 is electrically connected to the input end of the cylinder 14.
[0026] In the above structure, by manipulating the switch 2, the output end of the cylinder 14 is used to push the baffle 9 to apply pressure to the upper cutter 15, so that the upper cutter 15 cuts the steel bar on the top of the lower cutter 22, thereby improving the practicability of the equipment.
[0027] In a preferred embodiment: a plurality of holes are formed in the inner wall of the adjusting plate 10, and the outer walls of the holes are rotatably connected to the outer wall of the rotating block 11.
[0028] In the above structure, since the inner walls of the holes are rotatably connected to the outer wall of the rotating block 11, the personnel can adjust according to the required length. The rotating block 11 is adjusted to the inner walls of different holes to achieve rotational connection, making the equipment widely applicable.
[0029] In a preferred embodiment: one end of the second spring 17 is fixed to the outer wall of the short rod 13, and the other end of the second spring 17 is fixed to the inner wall of the long cylinder 12.
[0030] In the above structure, since the other end of the second spring 17 is fixed to the inner wall of the long cylinder 12, the steel bar enters the inner wall of the machine body 1, passes through the top of the lower cutter 22, and moves to the top of the square plate 6. One end of the steel bar abuts against the outer wall of the bottom of the rotating block 11, so that the rotating block 11 pushes the baffle 9 through the adjusting plate 10 to overlap with the top of the upper cutter 15. When the steel bar cutting is completed, due to the elastic force of the second spring 17, the short rod 13 is slidably sleeved with the inner wall of the long cylinder 12, so that the baffle 9 disengages from the top of the upper cutter 15, and the steel bar cutting is recycled.
[0031] In a preferred embodiment: one end of the first spring 16 is fixed to the bottom of the round rod 8, and the other end of the first spring 16 is fixed to the inner wall of the cylinder 7.
[0032] In the above structure, the cylinder 14 is used to push the baffle 9 to apply pressure to the upper cutter 15. The upper cutter 15 compresses the first spring 16 through the round rod 8 and is slidably sleeved with the inner wall of the cylinder 7, so that the upper cutter 15 moves up and down in contact with the outer wall of the second spring 17 through compression to cut the steel bar.
[0033] Working principle: Place the device on the ground, place the steel bar on the top of the placement plate 4 by using an external force, drive the rotating wheel 20 to rotate by the motor 18, drive the driven wheel 21 to rotate through the belt 19 by the rotating wheel 20. The steel bar is located at the center of the two fixed plates 3, so that the two fixed plates 3 drive the steel bar to move into the inner wall of the machine body 1 during the rotation process, avoiding bending of the steel bar during cutting. The steel bar enters the inner wall of the machine body 1, passes through the top of the lower cutter 22, and moves to the top of the square plate 6. One end of the steel bar abuts against the outer wall of the bottom of the rotating block 11, so that the rotating block 11 pushes the baffle 9 to overlap with the top of the upper cutter 15 through the adjusting plate 10. When the cutting of the steel bar is completed, due to the elastic force of the second spring 17, the short rod 13 is slidably sleeved with the inner wall of the long cylinder 12, so that the baffle 9 disengages from the top of the upper cutter 15, and the steel bar is recycled after cutting. The baffle 9 is pushed by the cylinder 14 to pressurize the upper cutter 15. The upper cutter 15 compresses the first spring 16 through the round rod 8 and is slidably sleeved with the inner wall of the cylinder 7, so that the upper cutter 15 moves up and down in contact with the outer wall of the second spring 17 through compression to cut the steel bar.
[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
