[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In one embodiment, please refer to Figures 1-8, a steel bar bending machine for construction engineering, comprising a support platform 1, a supporting mechanism 2 and a bending mechanism 3;

[0030] The supporting mechanism 2 includes a clearance groove 24 arranged at the end of the support platform 1, the clearance groove 24 is arranged at the right end of the support platform 1, and support legs are arranged at the four corners of the lower surface of the support platform 1, so that the support platform 1 maintains a horizontal state, and a front-to-back fixed column 10 is arranged at the right end of the clearance groove 24, and the fixed column 10 is fixedly connected to the entire support platform 1, and semicircular side plates 11 are vertically arranged on the front and back sides of the fixed column 10, the left side of the semicircular side plate 11 is a vertical surface, and the right side of the semicircular side plate 11 is an arc surface, and the semicircular side plate 11 is provided with a plurality of slide grooves 19 radially distributed relative to the center of the fixed column 10. In the present application, eight slide grooves 19 are arranged, and the eight slide grooves 19 are just aligned with each other. The center angle of the circle should be 180 degrees, that is, the uppermost and lowermost slide grooves 19 are both vertically arranged, and the sliding plates 12 facing forward and backward are slidably connected inside the slide grooves 19, and all the sliding plates 12 move synchronously along the slide grooves 19. Support plates 13 are vertically arranged at the front and rear ends of the sliding plates 12 away from the fixed column 10, and the ends of the support plates 13 are rotatably connected to the supporting rollers 14 facing forward and backward, and in order to prevent slipping, the outside of the supporting rollers 14 can be wrapped with rubber material, and the rubber material can increase sufficient friction, so that the steel bars will not slide when being bent along the supporting rollers 14, so that the steel bars remain stable during the bending process;

[0031] The bending mechanism 3 includes a rotating frame 38 rotatably connected to the fixed column 10. The rotating frame 38 is a U-shaped structure. The front and rear ends of the rotating frame 38 are rotatably connected to the front and rear sides of the fixed column 10, and guide grooves 36 are provided on the front and rear side walls of the rotating frame 38. The guide grooves 36 are slidably connected to the slider 37, and the slider 37 is provided with a front-to-back pressure rod 39.

[0032] In a case of this embodiment, a rotating sleeve 16 is rotatably connected to the middle of the fixed column 10. The rotating sleeve 16 is sleeved on the middle of the fixed column 10 and rotates relative to the fixed column 10. Rotating rings 17 coaxial with and fixedly connected to the rotating sleeve 16 are arranged on the front and rear sides of the rotating sleeve 16. One end of a push rod 18 is rotatably connected to the outer side of the rotating ring 17, and the other end of the push rod 18 is rotatably connected to a sliding plate 12. Therefore, when the rotating sleeve 16 rotates, the rotating sleeve 16 pushes the sliding plate 12 to move along the sliding groove 19 through the push rod 18, so that the sliding plates 12 on the semi-circular side plates 11 can all extend or contract relative to the fixed column 10 synchronously. And a rotation driving assembly 15 is arranged in the middle of the support table 1. The rotation driving assembly 15 can push the rotating sleeve 16 to rotate relative to the fixed column 10. At the same time, a feeding assembly 9 is arranged above the support table 1, and the top end of the feeding assembly 9 is at the same height as the support roller 14 at the top end.

[0033] In a case of this embodiment, the rotation driving assembly 15 includes a push screw rod 20 arranged horizontally in the middle of the support table 1. The left and right sides of the push screw rod 20 are rotatably connected to first bearing seats 23. The lower sides of the first bearing seats 23 are fixedly connected to the support table 1. A nut 21 is threadedly connected to the middle of the push screw rod 20. The upper end of the left end of a support rod 22 is rotatably connected to the nut 21, and the right end of the support rod 22 is rotatably connected to the outer wall of the rotating sleeve 16. And a second bearing seat 28 is arranged on the front side of the middle of the support table 1. The middle of a rotating shaft 27 is rotatably connected to the second bearing seat 28. A first bevel gear 26 is fixedly connected to the rear end of the rotating shaft 27. The first bevel gear 26 meshes with a second bevel gear 25, and the second bevel gear 25 is fixedly connected to the left end of the push screw rod 20. Therefore, by rotating the rotating shaft 27, the push screw rod 20 rotates, so that the support rod 22 pushes the rotating sleeve 16 to rotate relative to the fixed column 10. And due to the self-locking characteristic of the screw nut 21 itself, when the rotation angle of the rotating sleeve 16 is completed, it can be automatically locked, making the stability of the whole device better.

[0034] In a case of this embodiment, the feeding assembly 9 includes sliding sleeves 4 arranged on the support table 1. The sliding sleeves 4 are vertically arranged at the four corners of the upper surface of the support table 1. The lower ends of sliding rods 5 are slidably connected above the sliding sleeves 4, and the upper ends of the sliding rods 5 are fixedly connected to a horizontally arranged placing rack 6. The placing rack 6 is in a square frame structure with a hole in the middle. A plurality of placing rollers 7 arranged front and rear are rotatably connected inside the placing rack 6 from left to right. And fixing rods 8 arranged horizontally are arranged on the front and rear sides of the right end of the placing rack 6. The right ends of the fixing rods 8 are fixedly connected to the upper ends of the uppermost support plates 13, so that the placing rollers 7 and the uppermost support roller 14 are at the same height.

[0035] In a case of this embodiment, a third bearing seat 31 is provided on the outer side of the rotating frame 38. The third bearing seat 31 is rotatably connected to a synchronous rotating sleeve 32 arranged parallel to the rotating frame 38. The lower end of the synchronous rotating sleeve 32 is fixedly connected to a driven bevel gear 30. The driven bevel gear 30 is meshed and connected to a fixed bevel gear 29. The fixed bevel gear 29 is fixedly connected to the front and rear sides of the fixed column 10. And a synchronous rotating rod 33 is slidably connected above the synchronous rotating sleeve 32. The upper end of the synchronous rotating rod 33 is fixedly connected to a fourth bevel gear 34. The fourth bevel gear 34 is meshed and connected to a third bevel gear 35. The third bevel gear 35 is fixedly connected to the end of the pressure lever 39. Therefore, when the rotating frame 38 rotates around the fixed column 10, due to the meshing connection between the fixed bevel gear 29 and the driven bevel gear 30, the pressure lever 39 will also rotate. And fixed blocks 40 are arranged on the front and rear sides of the pressure lever 39. The fixed blocks 40 are rotatably connected to rotating rollers 41 facing the front and rear directions. Thus, the rotating rollers 41 will rotate around the pressure lever 39. And a lifting screw rod 43 is threadedly connected to the middle of the rotating frame 38. The end of the lifting screw rod 43 is rotatably connected to a lifting frame 42. The lifting frame 42 is of a U-shaped structure. The front and rear ends of the lifting frame 42 are fixedly connected to sliding blocks 37. The height of the sliding blocks 37 is adjusted by rotating the lifting screw rod 43.

[0036] During the implementation of this embodiment, first, the entire support table 1 is stably placed at the construction site. According to the construction requirements of the steel bars, it is judged how large a diameter arc the steel bars need to be bent into. At this time, the rotating shaft 27 can be rotated. The rotating shaft 27 makes the pushing screw rod 20 rotate through a gear transmission method. The pushing screw rod 20 makes the rotating sleeve 16 rotate around the fixed column 10 through the cooperation of the nut 21 and the support rod 22. The rotating sleeve 16 pushes the sliding plate 12 to rotate along the sliding groove 19 through the push rod 18. Thus, the radius of the arc formed by the plurality of support rollers 14 meets the requirements of steel bar bending. And at this time, the lifting screw rod 43 is rotated again. The lifting screw rod 43 drives the pressure lever 39 to move downward, so that the gap between the pressure lever 39 and the support rollers 14 meets the requirements of bending. The rotating frame 38 is rotated to the vertical state directly above, and the steel bars are placed on the placing frame 6 from left to right. And the steel bars move to the right along with the placing rollers 7. When the steel bars move between the pressure lever 39 and the uppermost support roller 14 and the length of the steel bars extending to the right meets the bending requirements, the movement of the steel bars is stopped.

[0037] At this time, rotate the rotating frame 38 clockwise. The rotating frame 38 drives the pressing rod 39 to rotate clockwise around the fixed column 10. And while the rotating frame 38 rotates clockwise, the rotating roller 41 will rotate around the pressing rod 39. That is, the rotating roller 41 will continuously push the steel bar to bend clockwise, improving the bending efficiency. After the rotating frame 38 rotates clockwise by a certain angle, the steel bar is bent on the supporting roller 14, and the rotation angle of the rotating frame 38 is selected according to the required bending angle, thus completing the bending process of the entire steel bar. The rotating frame 38 can be directly rotated to the lowest position. At this time, the steel bar can be drawn out from the right side, and the steel bar has completed the bending process.

[0038] The present invention is applicable to a steel bar bender for construction engineering. By setting the supporting roller 14 whose position can be adjusted, the steel bar can be bent into different curvatures. And during the bending process, the rotating roller 41 continuously squeezes and releases the steel bar, making the bending of the steel bar smoother and improving the bending efficiency.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
