[0002] In reinforced concrete, steel bars are an indispensable structural material. The processing and shaping of steel bars directly affect the strength of reinforced concrete structures and even the quality of the project. Generally, after steel bars are shaped in steel mills, for the convenience of transportation, most of the steel bars will be rolled into a round shape and bundled together before being sent to the construction site. During the construction process, the steel bars must first be straightened using a steel straightening machine, then the steel bars are hooped using a stirrup machine, and finally the stirrups are tied manually.

In the subsequent stirruping process, the steel bars are usually bent by a rotating wheel, and can only be bent at specified intervals, resulting in low flexibility in stirrup bending and limited applicability. In addition, the bent steel bars need to be cut manually, which is extremely inconvenient and affects the stirruping efficiency of the steel bars. Utility Model Content

This is the existing steel bar straightening machine structure, which will not be repeated here. Considering the stirrups and shearing of the steel bars after straightening, in the fixed A shearing assembly 5 is fixedly connected to one side of the fixed seat 1, and a side plate 6 is fixedly connected to the other side of the shearing assembly 5. The side plate 6 and the shearing assembly 5 are arranged vertically to ensure that the shearing assembly 5 works on one side of the side plate 6. Specifically, in order to realize the bending stirrups of the steel bars, a force-bearing wheel 7 is rotatably installed on the surface of the side plate 6, so that the straightened steel bars are moved to the surface of the force-bearing wheel 7. At the same time, a pressing wheel 10 is arranged on the other side of the force-bearing wheel 7, and a fixing plate 9 is fixedly connected to the top of the pressing wheel 10, and the fixing plate 9 is fixedly connected to the output end of the cylinder 8, and the cylinder 8 is fixedly connected to the surface of the side plate 6. Through such an arrangement, the cylinder 8 can drive the pressing wheel 10 to move downward on one side of the force wheel 7 through the fixing plate 9, so that the pressing wheel 10 squeezes the steel bars downward on one side to bend them, and the stirrups of the steel bars are realized through the successive bending processes. After bending, the steel bars need to be cut on one side.

[0027] See also Figure 1-Figure 5 In consideration of accurate shearing of the steel bars, a connection box 501 is included inside the shearing assembly 5, and two groups of shear knives 502 are symmetrically arranged inside the connection box 501, and the two groups of shear knives 502 are symmetrically telescopically arranged inside the connection box 501 about the horizontal axis, and a through hole is opened in the middle of the connection box 501 about the horizontal axis, so that the inside of the through hole can facilitate the passage of the steel bars, and in consideration of efficient shearing of the bent steel bars, the through hole is arranged on one side of the force wheel 7.

[0028] Furthermore, in order to achieve accurate cutting of the steel bars by the two sets of shearing knives 502, an upper mounting plate 503 is fixedly connected to the top of the upper shearing knife 502, and a lower mounting plate 508 is arranged in parallel below the upper mounting plate 503, and the lower mounting plate 508 is fixedly installed at the bottom end of the lower shearing knife 502. Considering the synchronous extension and retraction of the two sets of shearing knives 502, a first rack 504 is fixedly connected to the bottom end of the upper mounting plate 503, and a gear 505 is meshedly connected to the outer wall of the first rack 504. At the same time, a second rack 507 is meshedly connected to the outer wall of the gear 505, and the second rack 507 is fixedly It is installed on the surface of the lower mounting plate 508. Through such an arrangement, the gear 505 can realize the transmission of the racks on both sides, which is convenient for the two sets of shearing knives 502 to move synchronously.

At the same time, due to the synchronous arrangement of the racks on both sides of the shearing knives 502, the connecting plates 5011 are fixedly connected to the left and right sides of the connecting box 501, ensuring the rotation effect of the gears 505 on both sides.

[0029] See also Figure 1-Figure 5 In order to achieve the telescopic effect of the symmetrically arranged first rack 504 and second rack 507, a through groove for accommodating the telescopic activity of the first rack 504 is formed on the surface of the lower mounting plate 508. At the same time, a through groove for accommodating the telescopic activity of the second rack 507 is formed on the surface of the upper mounting plate 503, thereby ensuring the moving range of the rack and avoiding interference with the rack. In addition, in consideration of the drive of the shearing knife 502, the top end of the upper mounting plate 503 is fixedly connected to the output end of the electric push rod 5010. The electric push rod 5010 is fixedly installed on the inner top wall of the connection box 501, so that the upper shearing knife 502 can be driven by the electric push rod 5010 to move, thereby realizing the synchronous transmission of the lower shearing knife 502. At the same time, a telescopic spring 509 is fixedly connected to the bottom end of the lower mounting plate 508, and the bottom end of the telescopic spring 509 is fixedly connected to the inner bottom wall of the connection box 501. Through the setting of the telescopic spring 509, the support of the lower shearing knife 502 is better, thereby ensuring the accuracy of the rack transmission.

[0030] Working principle: When in use, the bent steel bar is passed through the first straightening wheel 2 and the second straightening wheel 4 in sequence, so that the steel bar is moved to the surface of the force wheel 7 through the through hole of the shearing assembly 5 after being straightened. After the steel bar extends to a specified length on the surface of the force wheel 7, the cylinder 8 is started, and the cylinder 8 drives the pressing wheel 10 to move downward, so that the pressing wheel 10 squeezes the steel bar downward on one side of the force wheel 7, thereby realizing the bending of the steel bar. After the successive output of the force wheel 7 and the successive bending of the pressing wheel 10, the steel bar that has been bent multiple times is hooped, and the steel bar after being bent is hooped. To shear the steel bars, the electric push rod 5010 drives the upper mounting plate 503 to move downward, so that the upper mounting plate 503 drives the upper shearing knife 502 to move downward. At the same time, under the action of the first rack 504 fixedly connected to the bottom end of the upper mounting plate 503, by arranging the first rack 504 and the second rack 507 on both sides of the gear 505, the second rack 507 synchronously drives the lower shearing knife 502 to move through the lower mounting plate 508, so that the upper and lower sets of shearing knives 502 synchronously cut the steel bars, thereby realizing the processing of the steel stirrups.
