Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar processing, and more specifically, relates to a portable integrated machine for bending and forming steel bars. Background Technique

[0002] Steel bars refer to the steel used in reinforced concrete, whose cross-section is circular, including plain round steel bars, ribbed steel bars and twisted steel bars; the steel bars used in reinforced concrete are mainly in two forms: straight bars and coiled bars. Among them, the coiled bars are made by bending the straight bars multiple times.

[0003] Currently, the bending of steel bars needs to be carried out on a steel bar bender; when the steel bar bender is performing bending processing, first place the steel bar in the positioning groove so that the part of the steel bar to be bent is between the fixed pin and the bending pin, and then the driving mechanism drives the bending pin to rotate around the fixed pin. The bending pin abuts against the steel bar and pushes the steel bar to bend, so that the steel bar obtains the required bending angle.

[0004] The inventor found that the current steel bar bender positions the steel bar through the positioning groove, and the positioning groove only plays a simple positioning role and cannot fix the steel bar. The steel bar is prone to move during the bending process, resulting in a decrease in the dimensional accuracy of the bent steel bar; in addition, due to the large reaction force generated during the bending process, there is a risk that the steel bar will break away from the positioning groove, so the safety performance of the positioning groove is also low.

[0044] Please refer to Figures 1 to 8 together to illustrate the portable integrated steel bar bending and forming machine provided in this application. The portable integrated steel bar bending and forming machine includes a mounting plate 1, a limiting structure 2 disposed on the mounting plate 1 and used to limit the movement of the steel bar 6, and a bending assembly 3; characterized in that the limiting structure 2 includes a plurality of fixed clamping plates 21, a plurality of movable clamping plates 22, and a linear driving mechanism 23.

[0045] A plurality of fixed clamping plates 21 are arranged at intervals along a straight line direction on the upper side of the mounting plate 1 and are all fixedly connected to the mounting plate 1.

[0046] A plurality of movable clamping plates 22 are arranged at intervals along a straight line direction on the upper side of the mounting plate 1 and are all slidably connected to the mounting plate 1 so as to be adapted to move towards or away from the fixed clamping plates 21, enabling the plurality of movable clamping plates 22 to be correspondingly connected to the plurality of fixed clamping plates 21 one by one.

[0047] The specific quantity of the plurality of fixed clamping plates 21 and the plurality of movable clamping plates 22 can be increased or decreased according to the length of the steel bar 6.

[0048] The linear driving mechanism 23 is connected to the plurality of movable clamping plates 22 and is used to drive the movable clamping plates 22 to move.

[0049] Wherein, the steel bar 6 is used to be fixed between the fixed clamping plates 21 and the movable clamping plates 22; the linear driving mechanism 23 can drive the plurality of movable clamping plates 22 to move towards or away from the fixed clamping plates 21 so as to achieve the purpose of clamping or releasing the steel bar 6.

[0050] In the embodiment of this application, by providing the limiting structure 2, one side of the steel bar 6 is in close contact with the plurality of fixed clamping plates 21, and the linear driving mechanism 23 is connected to the plurality of movable clamping plates 22, which can drive the plurality of movable clamping plates 22 to move towards the side of the fixed clamping plates 21 until the plurality of movable clamping plates 22 and the plurality of fixed clamping plates 21 cooperate to tightly clamp the steel bar 6, achieving the purpose of limiting the steel bar 6.

[0052] In some embodiments, please refer to Figure 1 and Figure 4 As a specific embodiment of the portable steel bar bending and forming machine provided by the present application, the adjacent sides of the fixed splint 21 and the movable splint 22 are provided with semicircular grooves 24 that penetrate in a straight line direction. When the fixed splint 21 and the movable splint 22 are connected, the corresponding two grooves 24 are connected and form a circular hole for the steel bar 6 to be embedded; anti-slip rubber pads are provided in the two grooves 24. When the fixed splint 21 and the movable splint 22 are connected, the anti-slip rubber pads in the two grooves 24 are suitable for abutting against the outer wall of the steel bar 6 to fix the position of the steel bar 6; the diameter of the groove 24 can be adjusted according to the model of the steel bar 6 to be bent.

[0053] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As a specific embodiment of the portable steel bar bending and forming machine provided in the present application, a plurality of support members 11 arranged in parallel along a straight line direction for supporting the steel bars 6 are provided on the mounting plate 1.

[0054] The upper side surface of each support member 11 has an arc-shaped groove, the radius of the arc-shaped groove is equal to the radius of the groove 24 , and the axial direction of the arc-shaped groove is parallel to the axial direction of the groove 24 .

[0055] When bending the steel bars 6, the staff only needs to place the steel bars 6 on multiple support members 11. The arc groove on each support member 11 is suitable for fitting the outer wall of the steel bars 6. At this time, the steel bars 6 are suitable for fitting with the grooves 24 on the fixed clamps 21. By adopting the above technical solution, the staff can conveniently complete the loading operation of the steel bars 6. Compared with the prior art, there is no need to hold the steel bars 6 with hands all the time, which improves the safety of the steel bars 6 during bending.

[0056] In some embodiments, please refer to Figures 1 to 7 As a specific implementation of the portable steel bar bending and forming machine provided in the present application, the linear drive mechanism 23 includes a screw rod 231 and a connecting rod 232 .

[0057] The screw 231 is rotatably arranged on the upper side of the mounting plate 1, and its axial direction is parallel to the upper side of the mounting plate 1 and perpendicular to the placement direction of the steel bars 6; the screw 231 is transmission-connected to a first rotating motor 233, and the first rotating motor 233 can rotate forward and reverse; the screw 231 is connected to the upper side of the mounting plate 1 through two rotating brackets.

[0058] The connecting rod 232 is connected to a plurality of movable clamping plates 22 to synchronize the movement of the plurality of movable clamping plates 22. The connecting rod 232 and the plurality of movable clamping plates 22 are fixed by bolt connection or welding; moreover, a threaded hole is provided on the connecting rod 232 along the axial direction of the screw rod 231, and the screw rod 231 is in threaded connection with the threaded hole; when the first rotating motor 233 drives the screw rod 231 to rotate, the connecting rod 232 moves along the axial direction of the screw rod 231 due to the guiding action of the thread.

[0059] By adopting the above technical solution, using one first rotating motor 233 can realize the synchronous movement of a plurality of movable clamping plates 22, with a compact layout and improved fixing efficiency of the steel bars 6.

[0060] In some embodiments, please refer to Figures 1 to 8 , as a specific implementation manner of the portable steel bar bending and forming integrated machine provided by the present application, the bending assembly 3 includes a rotating member 31, a fixed roller 32 and a bending roller 33.

[0061] The rotating member 31 is rotatably arranged on the mounting plate 1 in the up and down direction and is drivingly connected to a second rotating motor 34 so that the rotating member 31 can rotate about its own central axis.

[0062] The fixed roller 32 is coaxially connected to the upper side surface of the rotating member 31 for abutting against the side surface of the steel bar 6 facing the horizontal direction.

[0063] The bending roller 33 is fixedly connected to the upper side surface of the rotating member 31 and is arranged in parallel with the fixed roller 32 for moving to abut against the steel bar 6 as the rotating member 31 rotates, so that the steel bar 6 undergoes a bending deformation.

[0064] By adopting the above technical solution, when performing the bending process of the steel bar 6, the steel bar 6 is placed between the fixed roller 32 and the bending roller 33. When the second rotating motor 34 is started to drive the rotating member 31 to rotate, during this process, the bending roller 33 moves around the central axis of the fixed roller 32. At the same time, the bending roller 33 abuts against the steel bar 6 and pushes the steel bar 6 to twist around the fixed roller 32, that is, to make the steel bar 6 undergo a bending deformation. The staff can control the bending angle of the steel bar 6 by controlling the rotation angle of the second rotating motor 34.

[0065] In some embodiments, please refer to Figures 1 to 8 , as a specific implementation manner of the portable steel bar bending and forming integrated machine provided by the present application, the outer peripheral walls of the fixed roller 32 and the bending roller 33 both have a positioning groove 35 in a ring shape for the steel bar 6 to be embedded.

[0066] By adopting the above technical solution, when the steel bar 6 is placed between the fixed roller 32 and the bending roller 33, the steel bar 6 is suitable for being embedded in the two positioning grooves 35. During the bending process of the steel bar 6, the positioning grooves 35 can also prevent the steel bar 6 from deviating up and down, thereby affecting the bending quality of the steel bar 6.

[0067] In some embodiments, please refer to Figures 1 to 7 As a specific implementation of the portable steel bar bending and forming machine provided in the present application, the portable steel bar bending and forming machine also includes a chassis 4.

[0068] The chassis 4 has a structure with a hollow interior and an open top, and is made of high-strength steel, which can ensure that the internal components are not damaged.

[0069] The mounting plate 1 is disposed in the chassis 4 and is transmission-connected with a lifting drive component 5; the lifting drive component 5 may be an electric telescopic rod.

[0070] By adopting the above technical solution, the electric telescopic rod is started and drives the mounting plate 1 to move upward or downward, so that the mounting plate 1 becomes liftable. When the mounting plate 1 moves downward, it is stored in the storage box, which reduces the space occupied by the entire device, thereby improving the convenience of the device; when the steel bar 6 needs to be bent, it only needs to start the electric telescopic rod to drive the mounting plate 1 to move upward to the upper opening of the chassis 4. Since the limiting member and the bending assembly 3 are both arranged on the upper side of the mounting plate 1, the bending process of the steel bar 6 will not be interfered with by the chassis 4.

[0071] In some embodiments, please refer to Figures 1 to 7 As a specific embodiment of the portable steel bar bending and forming machine provided in the present application, a traction rod 41 is slidably connected in the chassis 4, and the traction rod 41 can be moved to the upper side or the lower side of the mounting plate 1.

[0073] In some embodiments, please refer to Figures 1 to 7 As a specific embodiment of the portable steel bar bending and forming machine provided in the present application, a handle 42 is connected to the traction rod 41; when the traction rod 41 moves to the upper side of the mounting plate 1, the handle 42 is suitable for being set back to the mounting plate 1; the handle 42 has an anti-slip sleeve.

[0074] By adopting the above technical solution, the arrangement of the handle 42 facilitates the staff to hold it, improving the operation comfort.

[0075] In some embodiments, as a specific implementation manner of the portable steel bar bending and forming integrated machine provided by the present application, a plurality of moving wheels 43 are arranged in parallel on the bottom surface of the chassis 4.

[0076] By adopting the above technical solution, the staff can drag and carry the chassis 4 body by holding the handle 42 and cooperating with the plurality of moving wheels 43, further improving the portability of the device.

[0077] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
