Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to a steel bar bending device. Background Art

[0002] In construction, steel bars are commonly used building materials. Since steel bars are straight, they need to be bent during actual use. However, it is laborious to bend steel bars manually, so a steel bar bending device is needed.

[0003] Announcement No.: CN221047180U A steel bar processing bending machine comprises a workbench, an arc groove is provided on the top of the workbench, a limit column is fixedly provided on the top of the workbench, a protective mechanism is provided on the top of the workbench, and a bending power assembly is provided at the bottom of the workbench. The steel bar is pressed downward through the inclined surface of the blocking claw. The inclined surface of the blocking claw is subjected to pressure, so that the movable plate is driven to move to the left along the fixed rod, so that the steel bar enters between the movable limit plate and the limit seat, and the spring is contracted at the same time. When the blocking claw loses pressure, the elastic force of the spring causes the movable plate to drive the blocking claw to reset, thereby sealing and protecting the top of the steel bar. The hydraulic cylinder is started, and the hydraulic cylinder causes the hydraulic push rod to extend. The extension of the hydraulic push rod drives the movable limit plate to move, so that the movable limit plate and the limit seat clamp the steel bar, and the steel bars of different thicknesses and models are quickly clamped and fixed.

[0004] However, in the above document, when it is necessary to load the steel bars, manpower is used to press the steel bars downward through the inclined surface of the blocking claws, so that the steel bars fall between the movable limit plate and the limit seat, and then the steel bars are manually moved so that the part of the steel bars that need to be bent is aligned with the limit column, and then the hydraulic cylinder is started to clamp the movable limit plate and the limit seat to clamp the steel bars. After the steel bars are bent, they also need to be removed manually. Such reciprocating operations are not only time-consuming and labor-intensive, but also pose certain safety hazards.

[0005] Therefore, it is necessary to invent a steel bar bending device. Utility Model Content

[0006] The purpose of the utility model is to solve the problems raised in the above background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel bar bending device, comprising a workbench, a limit seat and a movable limit plate are installed on one side of the upper end of the workbench, the limit seat and the movable limit plate are arranged oppositely, a movable groove is opened on the surface of the workbench, a conveyor belt is installed on the inner side of the movable groove, a guide seat is arranged on the side of one end of the conveyor belt away from the workbench, a feeding assembly is installed on the upper end of the guide seat, a material storage box is installed on the upper end of the feeding assembly, and a rotating assembly is installed on the upper end of the side of the workbench away from the guide seat;

[0008] A lower roller is installed in the inner cavity at one end of the movable groove. The lower roller is located at the end of the conveyor belt away from the guide seat. A micro motor is arranged on one side of the lower roller. A driving shaft is installed at the output end of the micro motor. The driving shaft movably runs through the middle of the lower roller.

[0009] Based on the above characteristics: the loading component can intermittently discharge the steel bars in the storage box one by one. At this time, the single steel bar will roll onto the conveyor belt through the guide seat. When the micro motor is started, the lower roller can be driven to rotate through the drive shaft. At this time, the conveyor belt will also rotate synchronously, which is convenient for conveying the steel bars falling on the conveyor belt forward. When the end of the steel bar away from the guide seat extends out of the conveyor belt, one end of the steel bar will be inserted between the lower roller and the rotating component. As the lower roller rotates, the lower roller will drive the steel bar to move, and the rotating component will also rotate in the opposite direction to assist in the displacement. When the steel bar moves to the position that needs to be bent, the hydraulic cylinder can push the movable limit plate to move, so that the steel bar is clamped and fixed between the movable limit plate and the limit seat. When the steel bar is bent, the hydraulic cylinder can push the movable limit plate away from the limit seat. At this time, the lower roller can continue to be driven to rotate, which is convenient for the bent steel bar to continue to move away from the workbench.

[0010] Preferably, a limiting column is fixedly installed in the middle of the upper end of the workbench, and an arc-shaped groove is opened on the surface of one side of the workbench close to the limiting column, and a bending column movably penetrates the interior of the arc-shaped groove.

[0011] Based on the above characteristics: when the steel bar needs to move to the limit column and the bending column, the bending column can be driven to move by the driving device. At this time, the bending column will bend the steel bar through the arc groove guiding movement.

[0012] Preferably, a baffle is installed at intervals on one side of the conveyor belt away from the guide seat.

[0013] Based on the above characteristics: the baffle can be limited on one side of the conveyor belt to prevent the steel bars from falling.

[0014] Preferably, a guide groove is provided at the upper end of the guide seat, a discharge groove is provided at one side of the guide seat, an inclined panel is installed at the lower end of the discharge groove, and the inclined panel is located at one side of the upper end of the conveyor belt.

[0015] Based on the above characteristics: when the feeding assembly discharges the steel bars individually, the steel bars will fall to the inner side of the guide seat through the guide groove, and then will slide onto the conveyor belt through the discharge groove and the inclined plate.

[0016] Preferably, the loading assembly includes a protective shell and a turntable installed in the inner cavity of the protective shell, a driving motor is installed on one side of the outer end of the protective shell, and a circular array of grooves is opened on the surface of the turntable.

[0017] Based on the above characteristics: when the steel bars need to be dropped onto the conveyor belt, the driving motor can drive the turntable to rotate through the shaft at the output end. When the groove on the surface of the turntable rotates upward and is aligned with the bottom of the storage box, the single steel bar at the bottom of the storage box will fall into the groove above. As the turntable rotates, when the groove containing the steel bars rotates downward, the steel bars will fall into the guide seat for discharge.

[0018] Preferably, an upper through hole is provided at the upper end of the protective shell, and a lower through hole is provided at the lower end of the protective shell.

[0019] Based on the above characteristics: it is convenient for intermittent feeding of steel bars.

[0020] Preferably, the rotating assembly includes a fixed frame and an upper roller installed in the middle of the fixed frame, a connecting shaft is installed between the upper roller and the fixed frame, connecting rods are symmetrically installed on both sides of the fixed frame, and lifting cylinders are symmetrically arranged at the lower end of the connecting rod away from the fixed frame.

[0021] Based on the above characteristics: the lifting cylinder can drive the fixed frame to rise and fall through the connecting rod, so that the distance between the upper roller and the lower roller can be adjusted according to the diameter of the steel bar, so that the steel bar can be rolled and clamped. When the lower roller rotates to drive the steel bar to move, the upper roller will also rotate in the opposite direction above the steel bar.

[0022] The beneficial effects of the utility model are:

[0023] 1. It is convenient for automatic loading of a single steel bar. When multiple steel bars need to be bent, first put the multiple steel bars into the storage box, and then the driving motor can drive the turntable to rotate through the shaft at the output end. When the groove on the surface of the turntable rotates to the top and aligns with the upper through hole, the lowest steel bar in the storage box will fall into the groove above the turntable through the upper through hole. As the turntable rotates, when the groove with the steel bar rotates to the bottom and aligns with the lower through hole, the steel bar will fall into the guide groove through the lower through hole, and then the steel bar will slide onto the conveyor belt through the discharge chute and the inclined plate. When the conveyor belt rotates and drives, the steel bar can be moved for loading.

[0024] 2. It is convenient for the bent steel bars to be unloaded by themselves. When the conveyor belt transports the steel bars forward, one end of the steel bar will be inserted between the lower roller and the upper roller. At this time, the lifting cylinder can drive the fixed frame to lift and adjust through the connecting rod, which is convenient for adjusting the distance between the upper roller and the lower roller according to the diameter of the steel bar, so that the steel bar can be rolled and clamped. When the steel bar is bent, as the lower roller rotates, the lower roller and the upper roller will drive the steel bar to move, so that the bent steel bar continues to move away from the workbench, without manual material removal, eliminating safety hazards.

[0025] 3. The baffle and guide seat are symmetrically arranged on both sides of one end of the conveyor belt. When the steel bar slides onto the conveyor belt through the guide seat, the baffle can limit the position on one side of the conveyor belt to prevent the steel bar from falling.

[0034] When it is necessary to bend multiple steel bars, first put the multiple steel bars into the storage box 8, and then the loading assembly 7 can intermittently discharge the steel bars in the storage box 8 one by one. At this time, the single steel bar will roll onto the conveyor belt 5 through the guide seat 6. When the micro motor 42 is started, the lower roller 41 can be driven to rotate through the drive shaft 43. At this time, the conveyor belt 5 will also rotate synchronously, which is convenient for conveying the steel bars falling on the conveyor belt 5 forward. When one end of the steel bar is away from the guide seat 6 and extends out of the conveyor belt 5, one end of the steel bar will be inserted between the lower roller 41 and the rotating assembly 9. At this time, the rotating assembly 9 can adjust the height according to the diameter of the steel bar, which is convenient for the rotating assembly 9 and the lower roller 41 to be The steel bar is clamped in the middle.

When the steel bar moves to the position where it needs to be bent, the hydraulic cylinder can push the movable limit plate 3 to move, so that the steel bar is clamped and fixed between the movable limit plate 3 and the limit seat 2. When the steel bar is bent, the hydraulic cylinder can push the movable limit plate 3 away from the limit seat 2. At this time, the lower roller 41 can continue to be driven to rotate, so that the bent steel bar continues to move.

[0040] When the feeding assembly 7 discharges the steel bars individually, the steel bars will fall into the inner side of the guide seat 6 through the guide groove 61 , and then slide onto the conveyor belt 5 through the discharge groove 62 and the inclined plate 63 .

[0041] Preferably, the loading assembly 7 includes a protective shell 71 and a turntable 72 installed in the inner cavity of the protective shell 71 , a driving motor 73 is installed on one side of the outer end of the protective shell 71 , and a circular array of grooves 74 are provided on the surface of the turntable 72 .

[0042] When it is necessary to drop the steel bars onto the conveyor belt 5, the driving motor 73 can drive the turntable 72 to rotate through the shaft at the output end. When the groove 74 on the surface of the turntable 72 rotates upward and is aligned with the bottom of the storage box 8, the single steel bar at the lower end of the storage box 8 will fall into the groove 74 at the top (the capacity of the groove 74 can only accommodate one steel bar at most. If two or more steel bars need to be accommodated, it can be set according to needs). As the turntable 72 rotates, when the groove 74 containing the steel bars rotates downward, the steel bars will fall into the guide seat 6 for guidance and discharge.

When the lower roller 41 rotates to drive the steel bar to move, the upper roller 92 will also rotate in the opposite direction above the steel bar.

[0047] The use process of the utility model is as follows: when it is necessary to bend multiple steel bars, first put multiple steel bars into the storage box 8, and then the driving motor 73 can drive the turntable 72 to rotate through the shaft at the output end. When the groove 74 on the surface of the turntable 72 rotates to the top and aligns with the upper through hole 711, the lowest steel bar in the storage box 8 will fall into the groove 74 above the turntable 72 through the upper through hole 711. As the turntable 72 rotates, when the groove 74 with the steel bar rotates to the bottom and aligns with the lower through hole 712, the steel bar will fall into the guide groove 61 through the lower through hole 712, and then the steel bar will slide onto the conveyor belt 5 through the discharge trough 62 and the inclined plate 63. When the micro motor 42 is started, the drive shaft can be used to drive the conveyor belt 5. 43 drives the lower roller 41 to rotate, and the conveyor belt 5 will also rotate synchronously at this time, so that the steel bars on the conveyor belt 5 are transported forward. When the end of the steel bar away from the guide seat 6 extends out of the conveyor belt 5, one end of the steel bar will be inserted between the lower roller 41 and the upper roller 92. As the lower roller 41 rotates, the lower roller 41 and the upper roller 92 will drive the steel bar to move. When the steel bar moves to the position where it needs to be bent, the hydraulic cylinder can push the movable limit plate 3 to move, so that the steel bar is clamped and fixed between the movable limit plate 3 and the limit seat 2. When the steel bar is bent, the hydraulic cylinder can push the movable limit plate 3 away from the limit seat 2 to release the steel bar. At this time, the lower roller 41 can continue to be driven to rotate, so that the bent steel bar continues to move away from the workbench 1.
