Description

Technical Field

[0001] The utility model relates to the technical field of steel bars, and in particular to a steel bar straightening machine. Background Art

[0002] Rebar is a commonly used part in construction projects and plays a very important role in the process of urban construction. Rebars generally need to be straightened before use. The rebars passing through the straightening cylinder are straightened to achieve the straightening effect. Rebar straightening machines are widely used in construction projects, roads and bridges and other fields. They can process rebars efficiently and accurately, improving work efficiency and construction quality.

[0003] After searching, the existing patent publication number: CN220717610U discloses a steel bar straightening machine, including a straightening machine and a limit mechanism, a limit mechanism is set at one end of the straightening machine, and a steel bar disc is installed at one end of the limit mechanism. The steel bar straightening machine is provided with a support block, a first motor, a connecting rod, a stopper, an electric slide, a connecting shell, a screw, a stopper and a nut. Before straightening, the nut is loosened, the stopper is rotated outward to a horizontal position, the steel bar disc with steel bars is put on the connecting rod, one end of the steel bar disc is against the stopper, and then the stopper is rotated inward to a vertical position, the nut is tightened, and then the electric slide is operated to drive the connecting shell to move, and the stopper is driven to move on the connecting rod. When the stopper is against the other end of the steel bar disc, the electric slide stops running. When the straightening machine is running, the first motor is operated, and the connecting rod rotates to drive the steel bar disc to rotate, so that the steel bars are evenly transported to the inside of the straightening machine.

[0004] In the above scheme, during the construction of civil engineering projects, most of the steel bars are directly put into the straightening machine for straightening before being straightened, because the steel bars are often piled up for a long time and exposed to the air, so that there are more rust layers or protrusions caused by cement mortar on the surface of the steel bars. This will cause a certain degree of damage to the straightening wheels in the straightening machine, greatly reducing its service life, and will also affect the normal straightening effect of the straightening machine on the steel bars. The staff can generally use scrapers, steel wool, gauze and other tools to deal with the rusty steel bars before the steel bars enter the steel bar straightening device. However, the number of steel bars is generally large, which leads to not only high labor intensity for the staff, but also poor impurity removal quality and low efficiency, affecting the work efficiency of users. Therefore, a steel bar straightening machine is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a steel bar straightening machine, including an external machine 3 and a straightening component 8, a guide hole 9 is penetrated through the external side end of the external machine 3, a steel bar 1 is inserted inside the guide hole 9, the external side end of the external machine 3 is fixedly connected with a cutting component 4, the straightening component 8 is located between the internal side ends of the external machine 3, a cleaning mechanism is installed inside the external machine 3, the rust layer or cement mortar on the surface of the steel bar 1 is cleaned, the cleaning mechanism includes a driving component and a cleaning component, the driving component is located at the internal bottom end of the external machine 3, the cleaning component is located between the side end of the driving component and the internal side end of the external machine 3, a stabilizing frame 2 is fixedly installed on the outside of the external machine 3, so that the steel bar 1 is more stable when being put in, and a storage component is provided on the side end of the external end of the external machine 3 near the cutting component 4, which reduces the height difference between the steel bar 1 and the ground after being straightened and cut, thereby avoiding the secondary bending caused by the height difference after the steel bar 1 is straightened.

[0022] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the driving assembly includes a motor 6, which is fixedly mounted on the inner bottom end of the external machine 3, and a pulley 605 is fixedly mounted on the output end of the motor 6. A turntable frame 606 is fixedly mounted on the inner wall side end of the external machine 3, and a turntable 602 is rotatably connected to the side end of the turntable frame 606 (the turntable frame 606 may be composed of a bracket and a limit plate, and the bracket is fixedly connected to the inner wall of the external machine 3, and the limit plate is rotatably connected to the turntable 602. This rotatable connection may be to open a limit groove on the turntable 602 that is adapted to the limit plate, and to realize rotation and limiting by installing the limit plate in the limit groove. Therefore, the turntable 602 can be rotated and limited on the turntable frame 60 6), the outer end of the turntable 602 is fixedly connected with the pulley one 603, and a belt 601 is sleeved between the outer end of the pulley two 605 and the outer end of the pulley one 603, and the side end of the turntable 602 is rotatably connected with two sets of rotating rods 604 through bearings. During implementation, when the motor 6 is started, the motor 6 drives the pulley two 605 to rotate. Since the belt 601 is sleeved between the outer end of the pulley two 605 and the outer end of the pulley one 603, when the pulley two 605 rotates, it will drive the turntable 602 to rotate. At this time, the turntable 602 will drive the pulley one 603 to rotate. At this time, the rotation of the turntable 602 drives the two sets of rotating rods 604 to rotate together.

[0023] It should be noted that holes for the steel bars 1 to pass through are provided at the center of the turntable 602 and the center of the turntable frame 606 , and the steel bars 1 pass through the holes and extend into the straightening assembly 8 .

[0024] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, the cleaning component includes two groups of wire roller brushes 7, and the two groups of wire roller brushes 7 are fixedly connected to the outer end of the rotating rod 604. The side ends of the two groups of rotating rods 604 are fixedly connected with the first gears 702. The side ends of the inner wall of the outer machine 3 are fixedly connected with the inner gear ring 701. The two groups of first gears 702 are meshed with the inner gear ring 701. During implementation, when the turntable 602 rotates to drive the two groups of rotating rods 604 to rotate together, the two groups of wire roller brushes 7 will be driven to rotate together. At this time, the rotation of the two groups of rotating rods 604 will drive the two groups of first gears 702 to rotate. Since the two groups of first gears 702 are meshed with the inner gear ring 701, the two groups of wire roller brushes 7 will be driven to rotate by themselves, thereby realizing the brushing cleaning of the rust layer or cement mortar on the surface of the steel bar, preventing the steel bar 1 from directly entering the straightening machine for straightening so that the debris causes a certain degree of damage to the straightening component 8, preventing its service life from being reduced and affecting the straightening effect, and greatly improving the impurity removal quality and work efficiency.

[0025] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, the top of the stabilizing frame 2 is located at the bottom of the steel bar 1 , and the top of the stabilizing frame 2 is V-shaped, so that the steel bar 1 is more stable when being placed.

[0026] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, the storage assembly includes a support frame 5, the side end of the support frame 5 is fixedly connected to a storage rack 502, and the top of the support frame 5 is fixedly connected to an L-shaped bracket 501, which reduces the height difference between the steel bar 1 and the ground after it is straightened and cut, thereby avoiding secondary bending caused by the height difference after the steel bar is straightened.

[0027] It should be noted that the straightening component and the cutting component in the utility model are consistent with the structure and function of the prior art patent publication number CN220717610U, and can realize the straightening and cutting of steel bars, which will not be described in detail here.

[0028] Working principle: when it is necessary to straighten the steel bar 1, the steel bar 1 is inserted into the guide hole 9 through the top of the stabilizing frame 2 and enters the interior of the straightening machine, and the motor 6 is started at the same time. The motor 6 drives the second pulley 605 to rotate. Since a belt 601 is sleeved between the outer end of the second pulley 605 and the outer end of the first pulley 603, the rotation of the second pulley 605 will drive the turntable 602 to rotate, and the turntable 602 will drive the pulley 1 603 to rotate. At this time, the rotation of the turntable 602 drives the two sets of rotating rods 604 to rotate together, and the rotation of the two sets of rotating rods 604 will drive the two sets of wire roller brushes 7 to rotate together. At this time, the rotation of the two sets of rotating rods 604 will drive the two sets of first gears 702 to rotate. Since the two sets of first gears 702 are meshed with the inner gear ring 701, the two sets of wire roller brushes 7 will be driven to rotate, thereby achieving the rust removal on the surface of the steel bar. The brushing cleaning of the layer or cement mortar, etc., prevents the steel bar 1 from directly entering the straightening machine for straightening, so that the debris causes a certain degree of damage to the straightening component 8, thereby preventing its service life from being reduced and affecting the straightening effect. At the same time, the debris generated by cleaning will fall into the external machine 3. The side wall hinge of the external machine 3 is equipped with a door, and the debris is cleaned by opening the door. The cleaned steel bar 1 enters the straightening component 8 through the guide hole 9 for straightening, and the straightened steel bar 1 is transmitted out through the guide hole 9. When the steel bar 1 reaches the set length, the cutting component 4 cuts the steel bar 1. At this time, the finished steel bar 1 falls to the bracket 501, and then falls from the bracket 501 to the storage rack 502, reducing the height difference between the steel bar 1 and the ground after straightening and cutting, thereby avoiding the secondary bending caused by the height difference after the steel bar 1 is straightened.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
