Description

Technical Field

[0001] The present application relates to the technical field of steel bar bending machines, and in particular to a steel bar bending device. Background Art

[0002] Steel bar bending machine is one of the steel bar processing machines. The working mechanism is a horizontal working disc rotating on a vertical axis. The steel bar is placed between the center pin and the bending pin. The support pin is fixed on the machine bed. The center pin and the bending pin are installed on the working disc. The steel bar is bent when the disc rotates. In order to bend steel bars of various diameters, there are several holes on the working disc to insert the bending pins at different positions. The center pin can also be replaced with different diameters according to the diameter of the steel bar.

[0003] A steel bar bending machine usually bends straight steel bars into a rectangular or other regular shaped structure so that the steel bars are suitable for different construction environments. During the bending process, the steel bars need to be continuously delivered forward, and this step is usually performed manually. In order to ensure relative accuracy, workers need to be equipped with a measuring ruler to ensure that the size of each advancement is relatively accurate. However, due to the deviation of visual inspection, it is still possible that the bending position is unreasonable, which leads to the scrapping of the steel bars and cannot be used anymore, resulting in waste. At the same time, manual delivery of steel bars is also prone to accidental injuries such as pinching of hands. Therefore, in order to solve the above problems, the present application provides a steel bar bending device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problems of insufficient precision in manually delivering steel bars by existing steel bar bending machines and the susceptibility to accidental injuries, the present application provides a steel bar bending device.

[0006] The present application provides a steel bar bending device, comprising a box, a turntable is rotatably arranged at the center of the box, and a supporting structure matched with the turntable is arranged above the turntable, a pushing mechanism that can slide along the Y-axis direction is arranged on one side of the box, a finger cylinder is arranged on the pushing mechanism, and the finger cylinder is displaced along the X-axis direction under the action of the pushing mechanism;

[0007] A control mechanism is arranged inside the box body, and the control mechanism controls the finger cylinder to move a fixed length along the X-axis direction.

[0008] The displacement of the pushing mechanism on the box along the Y-axis direction allows it to flexibly switch its position according to the bending position of the steel bar and the thickness of the steel bar, thereby increasing the applicable scope of the lifting device. The fixed-length displacement of the finger cylinder along the X-axis direction allows the finger cylinder to move the steel bar to a set length, thereby completing the operation of pushing the steel bar forward without human intervention.

[0009] Preferably, the pushing mechanism includes a stepping motor and a threaded rod arranged at the output end of the stepping motor, and the threaded rod is threadedly connected to the sliding frame at the bottom of the finger cylinder.

[0010] Preferably, a notch is provided on one side of the box body where the pushing mechanism is arranged, and a track is provided at the end of the notch along the Y-axis direction, and a mounting frame is provided on the outer side of the stepping motor, and the frame is slidably connected to the track.

[0011] Preferably, two sliding rods are arranged on the frame parallel to the direction of the threaded rod, the midline position of the sliding frame is threadedly connected to the threaded rod, and both sides of the sliding frame are slidably connected to the sliding rods.

[0012] Preferably, a driving motor is also provided inside the box, and the output end of the driving motor is connected to the turntable through a reduction mechanism.

[0013] Preferably, a control panel is rotatably provided on the outer side of the box, and the control panel is communicatively connected with the control mechanism.

[0014] Preferably, a support rod is provided on a side of the box body away from the notch.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] By setting a pushing mechanism on one side of the box, using the threaded rod in the pushing mechanism to axially transmit the finger cylinder, and cooperating with the stepping motor to accurately control the rotation angle, the flexible adjustment of the activity distance of the finger cylinder can be achieved to adapt to steel bars with different lengths of bending sections. Compared with the manual operation in the existing technology, the accuracy is improved and the probability of workers' hands being pinched is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is combined with Figure 1 - Figure 3 This application is described in further detail.

[0022] Embodiment 1:

[0023] Reference Figure 1 - Figure 3 A steel bar bending device includes a box body 1, a turntable 2 is rotatably arranged at the center of the box body 1, and a supporting structure 3 matched with the turntable 2 is arranged above the turntable 2. A driving motor 92 is also arranged inside the box body 1, and the output end of the driving motor 92 is connected to the turntable 2 through a reduction mechanism 91. The reduction mechanism 91 effectively reduces the rotation speed of the driving motor 92 and increases the torque, thereby increasing the bending effect of the turntable 2 on the steel bar.

[0024] A push mechanism 6 that can slide along the Y-axis direction is provided on one side of the box body 1, and a finger cylinder 7 is provided on the push mechanism 6, and the finger cylinder 7 is displaced along the X-axis direction under the action of the push mechanism 6;

[0025] A control mechanism 8 is disposed inside the box body 1 , and the control mechanism 8 controls the finger cylinder 7 to move a fixed length along the X-axis direction. A control panel 5 is rotatably disposed outside the box body 1 , and the control panel 5 is communicatively connected with the control mechanism 8 .

[0026] The pushing mechanism 6 includes a stepper motor 61 and a threaded rod 64 arranged at the output end of the stepper motor 61. The threaded rod 64 is threadedly connected to the sliding frame 65 at the bottom of the finger cylinder 7. The control mechanism 8 includes a single-chip microcomputer module, a data transmission module, etc. The single-chip microcomputer module and the control panel 5 and the stepper motor 61 are all connected in communication. The data information is input on the control panel 5 to enter the number of bending sections, the length of each bending section, etc. After the single-chip microcomputer processes the data, it is transmitted to the stepper motor 61 to control its rotation angle. The threaded rod 64 adopts multi-threaded threads to ensure stability while accelerating the transmission efficiency. Since the distance transported by the threaded rod 64 is constant when it rotates one circle, the two are proportional, so it is only necessary to convert the corresponding distance into the rotation angle of the threaded rod 64.

[0027] The threaded rod 64 rotates to transport the finger cylinder 7 to the preset position, and then the finger cylinder 7 contracts to clamp the outer wall of the steel bar. Then the stepper motor 61 rotates in the opposite direction, and the threaded rod 64 drives the finger cylinder 7 to move to the original position, thereby causing the upper steel bar to move. The displacement length of the finger cylinder 7 is the conveying length of the steel bar. This reciprocating process can complete the processing of different bending lengths in the same bending direction;

[0028] During the processing, the turntable 2 rotates and applies force to the steel bar to make the steel bar close to the supporting structure. After obtaining a stable clamping force, the finger cylinder 7 releases the steel bar and moves backward synchronously when the steel bar is bent to prepare for the next bending. When it is necessary to bend longer than the threaded rod 64, the finger cylinder 7 conveys the steel bar forward. At this time, the turntable 2 and the supporting structure 3 cooperate to clamp the steel bar, but no bending operation is performed. Then the finger cylinder 7 is released and two or more conveying operations are performed to complete the bending operation at a longer length interval.

[0029] A notch 11 is provided on one side of the box body 1 on which the pushing mechanism 6 is arranged, and a track 63 is provided at the end of the notch 11 along the Y-axis direction. A mounting frame 62 is provided on the outer side of the stepping motor 61, and the frame 62 is slidably connected to the track 63. A slider is provided at the top of the frame 62, which is slidably connected to the track 63, so as to realize the displacement of the pushing mechanism 6 in the Y-axis direction. Two sliding rods 66 are provided on the frame 62 parallel to the direction of the threaded rod 64. The midline position of the sliding frame 65 is threadedly connected to the threaded rod 64, and the two sides of the sliding frame 65 are slidably connected to the sliding rod 66. The sliding rod 66 is used to limit the sliding frame 65 to ensure that it can be displaced axially along the threaded rod 64.

[0030] A support rod 4 is provided on one side of the box body 1 away from the notch 11, and the support rod 4 is used to support the bent steel bars, thereby avoiding angle deflection and causing errors in the bending position.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
