Description

Technical Field

[0001] The utility model belongs to the field of steel bar bending, and particularly relates to a steel bar bending machine. Background Art

[0002] Steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, and sometimes square with rounded corners, including plain round bars, ribbed bars, and twisted bars. When bending steel bars, a steel bar bending machine is mostly used. However, the bending spacing of existing steel bar bending machines is constant, resulting in the phenomenon that when bending steel bars with different diameters, it is easy to be unable to put them in or the space is too large to bend the steel bars normally, causing the bending to be unable to proceed. Moreover, when bending multiple steel bars simultaneously, the steel bars are prone to being placed in a chaotic manner and unable to be kept on the same vertical line, seriously affecting the normal progress of subsequent bending. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to solve the disadvantages in the background art and propose a steel bar bending machine to solve the problems existing in the prior art.

[0004] To achieve the above purpose, the utility model provides a steel bar bending machine, including a machine shell. A bearing seat is fixedly installed at the upper end of the machine shell near one side edge. A second limiting baffle is fixedly installed at the rear edge of the upper end surface of the bearing seat. A first limiting baffle is arranged in front of the second limiting baffle. The first limiting baffle and the second limiting baffle are symmetrically arranged. An adjusting member is arranged between the first limiting baffle and the bearing seat. A turntable is rotatably installed through the upper end of the machine shell near the other side edge. A limiting column is rotatably installed in the middle of the upper end of the turntable. The limiting column is connected to the machine shell. A bending column is arranged near the edge of the upper end of the turntable. A pushing member is arranged between the bending column and the turntable. A limiting plate is fixedly installed at the other side edge of the upper end surface of the machine shell.

[0005] In the above technical solution, preferably, a servo reduction motor is fixedly installed inside the machine shell. The output end of the servo reduction motor is fixed to the middle of the lower end of the turntable. A column frame is fixedly installed on the outer surface of the limiting column. The end of the column frame is fixed to the machine shell. The upper ends of the first limiting baffle and the second limiting baffle are both arc-shaped.

[0006] Preferably, the adjusting member includes an extending seat fixedly installed at the front edge of the upper end of the bearing seat. A first threaded rod is screwed through the front end of the extending seat. The rear end of the first threaded rod is rotatably connected to the middle of the front end of the first limiting baffle.

[0007] Preferably, sliding grooves are formed on both sides of the protruding seat. Guide ears are fitted and installed inside the sliding grooves. The end of the guide ear is fixed to the first limiting baffle. The front end of the first threaded rod is coaxially and fixedly installed with a handwheel.

[0008] Preferably, the pushing member includes a bearing frame embedded through the upper end surface of the turntable. A second threaded rod is rotatably installed between the front and rear end surfaces inside the bearing frame. The second threaded rod penetrates out from the front of the bearing frame. An adjusting seat is screwed on the outer surface of the second threaded rod. The lower end of the bending column is connected to the upper end of the adjusting seat.

[0009] Preferably, anti-detachment strips extend from both sides inside the bearing frame. The anti-detachment strips penetrate through the side surface of the adjusting seat, and the anti-detachment strips are in sliding fit with the adjusting seat.

[0010] Compared with the prior art, the utility model has the following beneficial effects: A plurality of steel bars are sequentially placed between the first limiting baffle and the second limiting baffle to limit the stacked plurality of steel bars by using the first limiting baffle and the second limiting baffle, so that they are neatly kept on the same vertical line to avoid the phenomenon that the placement of a plurality of steel bars is chaotic and affects bending, thereby ensuring the normal progress of the bending operation. At the same time, by directly rotating the first threaded rod, the first limiting baffle can be pushed. At this time, the guide ear slides along the sliding groove to assist the movement of the first limiting baffle to adjust the distance between the first limiting baffle and the second limiting baffle to adapt to steel bars of different diameters. Similarly, by directly rotating the second threaded rod, the adjusting seat screwed on the second threaded rod moves to drive the bending column to move, so as to adjust the distance between the bending column and the limiting column to adapt to bending of steel bars of different diameters and meet the construction requirements.

A first limiting baffle 3 is arranged in front of the second limiting baffle 4. The first limiting baffle 3 and the second limiting baffle 4 are symmetrically arranged. The first limiting baffle 3 and the second limiting baffle 4 play a role in limiting multiple steel bars. An adjusting member is arranged between the first limiting baffle 3 and the bearing seat 2. A turntable 5 is rotatably installed through the upper end near the other - side edge of the machine shell 1. The turntable 5 plays a role in driving the bent column 9 to rotate. A limiting column 7 is rotatably installed in the middle of the upper end of the turntable 5. The limiting column 7 is connected to the machine shell 1. The limiting column 7 plays a role in cooperating with the bent column 9 for bending. A bent column 9 is arranged near the edge of the upper end of the turntable 5. A pushing member is arranged between the bent column 9 and the turntable 5. A limiting plate 6 is fixedly installed at the other - side edge of the upper end surface of the machine shell 1. The limiting plate 6 plays a role in limiting the bending length.

[0018] A servo reduction motor 10 is fixedly installed inside the machine shell 1. The output end of the servo reduction motor 10 is fixed to the middle of the lower end of the turntable 5. The servo reduction motor 10 plays a role in driving the turntable 5 to rotate. The rotation angle of the turntable 5 driven by the servo reduction motor 10 can be controlled as required. Since controlling the rotation angle of the servo reduction motor 10 is an existing technology and has been widely used, it is not elaborated in detail here. A column frame 8 is fixedly installed on the outer surface of the limiting column 7. The column frame 8 plays a role in fixing the limiting column 7. The end of the column frame 8 is fixed to the machine shell 1. The upper ends of both the first limiting baffle 3 and the second limiting baffle 4 are arc - shaped, which is convenient for the steel bars to be put in.

[0019] The adjusting member includes a protruding seat 11 fixedly installed at the front edge of the upper end of the bearing seat 2. A first threaded rod 12 is screwed through the front end of the protruding seat 11. The protruding seat 11 serves to carry the first threaded rod 12. The rear end of the first threaded rod 12 is rotatably connected to the middle of the front end of the first limiting baffle 3. The first threaded rod 12 serves to drive the first limiting baffle 3 to move.

[0020] Both sides of the protruding seat 11 are provided with sliding grooves 13. A guiding ear 14 is fitted inside the sliding grooves 13. The sliding grooves 13 and the guiding ears 14 serve to guide the first limiting baffle 3. The end of the guiding ear 14 is fixed to the first limiting baffle 3. A handwheel 19 is coaxially and fixedly installed at the front end of the first threaded rod 12. The handwheel 19 serves to facilitate the rotation of the first threaded rod 12.

[0021] The pushing member includes a bearing frame 15 embedded through the upper end surface of the turntable 5. A second threaded rod 16 is rotatably installed between the front and rear end faces inside the bearing frame 15. The second threaded rod 16 penetrates out from the front end of the bearing frame 15. The bearing frame 15 serves to carry the second threaded rod 16. A hexagonal groove is provided at the front end of the second threaded rod 16 to facilitate rotation with a hexagonal wrench. An adjusting seat 18 is screwed onto the outer surface of the second threaded rod 16. The lower end of the bending post 9 is connected to the upper end of the adjusting seat 18. The adjusting seat 18 serves to carry the bending post 9.

[0022] Anti - detachment strips 17 extend from both sides inside the bearing frame 15. The anti - detachment strips 17 penetrate through the side surface of the adjusting seat 18. The anti - detachment strips 17 serve to prevent the adjusting seat 18 from rotating. The anti - detachment strips 17 are in sliding fit with the adjusting seat 18.

[0023] During bending, rotate the first threaded rod 12 to push the first limiting baffle 3. At this time, the guiding ear 14 slides along the sliding groove 13 to assist the movement of the first limiting baffle 3, so as to adjust the distance between the first limiting baffle 3 and the second limiting baffle 4 to adapt to the diameter of the bent steel bar. Similarly, directly rotate the second threaded rod 16 to move the adjusting seat 18 screwed on the second threaded rod 16, so as to drive the bending post 9 to move, and adjust the distance between the bending post 9 and the limiting post 7 to adapt to the diameter of the bent steel bar. Then, place the steel bar between the first limiting baffle 3 and the second limiting baffle 4 and between the bending post 9 and the limiting post 7 in sequence. At the same time, the end of the steel bar abuts against the limiting plate 6. Then, the servo - reduction motor 10 works to drive the turntable 5 to rotate, and further drives the bending post 9 to rotate, so that the steel bar is bent with the limiting post 7 as the center.
