Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, and in particular to a steel bar bending device for building engineering. Background Technology

[0002] Steel bars are an essential building material in construction engineering. They can be divided into types such as reinforcing bars, stirrups, and scaffolding bars. They mainly bear the load in the building and can improve the seismic resistance and quality of the building. In construction, not only straight steel bars are used, but steel bar bending devices are often used to bend the steel bars. In the traditional way, steel bars are bent on the construction site by hand with tools.

[0003] Existing rebar bending equipment has a limited range of bending methods, typically only bending one rebar at a time or only one end of the rebar at a time, which cannot meet the diverse needs of construction sites. Utility Model Content

[0005] This utility model provides a steel bar bending device for construction engineering, which overcomes the shortcomings of existing steel bar bending devices that have a relatively simple bending method for steel bars. Generally, they can only bend one steel bar at a time, or only bend one end of the steel bar at a time, which cannot meet the different needs of construction sites.

Detailed Implementation

[0019] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown, the present invention discloses a steel bar bending device for construction engineering, comprising a workbench 1, a shaping table 2, a fixing component 3, a bending component 4, a shaping component 5, and an upward pushing mechanism 6. The shaping table 2 is provided on the top surface of the workbench 1, and the two ends of the shaping table 2 are arc-shaped. The fixing component 3 is provided on the workbench 1 on both sides of the shaping table 2. The outer side walls of the shaping table 2 are provided with fixing grooves 21 for fixing steel bars. The shaping component 5 is provided on the top surface of the workbench 1 at a position directly opposite to the two ends of the shaping table 2. The bending component 4 is provided on the workbench 1 between the fixing component 3 and the shaping component 5. The bending component 4 is located on the extension line of the diagonal of the shaping table 2. The upward pushing mechanism 6 for pushing the steel bars upward is provided at the bottom of the workbench 1 at a position corresponding to the shaping table 2.

[0021] The fixing component 3 includes a first cylinder 31, a first piston rod 32, a first connecting block 33, and a clamping block 34. The first cylinder 31 is mounted on the worktable 1. The first piston rod 32 of the first cylinder 31 faces the shaping table 2. One end of the first piston rod 32 facing the shaping table 2 is fixedly connected to one side of the first connecting block 33. The other side of the first connecting block 33 is fixed to one side of the clamping block 34 by bolts. The other side of the clamping block 34 is provided with a clamping groove 341. The clamping groove 341 and the fixing groove 21 cooperate to clamp and fix the steel bar. The clamping groove 341 and the fixing groove 21 can be arc-shaped grooves to better adapt to the steel bar, resulting in a good clamping effect.

[0022] The bending component 4 includes a second cylinder 41, a second piston rod 42, a second connecting block 43, and a bending block 44. The second cylinder 41 is mounted on the worktable 1. The second piston rod 42 of the second cylinder 41 faces the shaping table 2. One end of the second piston rod 42 facing the shaping table 2 is fixedly connected to one side of the second connecting block 43. The other side of the second connecting block 43 is fixed to one side of the bending block 44 by bolts. The other side of the bending block 44 is arc-shaped.

[0023] The shaping component 5 includes a third cylinder 51, a third piston rod 52, a third connecting block 53, and a shaping block 54. The third cylinder 51 is mounted on the worktable 1. The third piston rod 52 of the third cylinder 51 faces the shaping table 2. One end of the third piston rod 52 facing the shaping table 2 is fixedly connected to one side of the third connecting block 53. The other side of the third connecting block 53 is fixed to one side of the shaping block 54 by bolts. The shape of the other side of the shaping block 54 is adapted to the end of the shaping table 2.

[0024] The pushing mechanism 6 includes a fourth cylinder 61, a pushing plate 62, and pushing rods 63. The fourth cylinder 61 is installed at the bottom of the workbench 1. The piston rod of the fourth cylinder 61 is set upward and its upper end is connected to the bottom of the pushing plate 62. Several pushing rods 63 are provided on the top of the pushing plate 62. The pushing mechanism 6 helps to quickly push out the bent steel bar and improves bending efficiency.

[0025] The worktable 1 around the shaping table 2 has a number of push holes 11 evenly distributed for the push rod 63 to push out.

[0026] In a construction site, when it is necessary to bend two steel bars at once, the two steel bars can be placed in the fixing slots 21 on both sides of the shaping platform 2. Then, the two first cylinders 31 are activated to drive the two first piston rods 32 to move, which in turn drives the clamping blocks 34 on both sides of the shaping platform 2 to clamp the two steel bars respectively. Then, the second cylinder 41 of one of the pair of bending parts 4 (two bending parts 4 located on a diagonal line of the shaping platform 2) is activated to drive its second piston rod 42 to move through the bending block 44 to bend one end of the two steel bars. During bending, the two steel bars are staggered (not bent at the same end). Then, the third cylinder 51 of the two shaping parts 5 is activated to drive its third piston rod 52, which in turn drives the two shaping blocks 54 to move towards both ends of the shaping platform 2 to shape the ends of the two steel bars after bending. After the shaping is completed, the fourth cylinder 61 is activated to drive its piston rod to move upward, which drives the upper push rod 63 to push the two bent steel bars upward, thus completing the bending of the two steel bars at once.

[0027] When it is necessary to bend both ends of the reinforcing bar simultaneously, the reinforcing bar can be placed in the fixing groove 21 on one side of the shaping platform 2. Then, the first cylinder 31 on one side of the shaping platform 2 is activated, which drives its piston rod 32 to move and thus drives the clamping block 34 to clamp the reinforcing bar. Then, the second cylinder 41 of the two bending parts 4 on one side of the shaping platform 2 is activated, which drives its second piston rod 42 to move. The two bending blocks 44 bend the two ends of the reinforcing bar respectively. Then, the third cylinder 51 of the two shaping parts 5 is activated, which drives its third piston rod 52 to move the two shaping blocks 54 towards the two ends of the shaping platform 2 to shape the two ends of the reinforcing bar after bending. After the shaping is completed, the fourth cylinder 61 is activated, which drives its piston rod to move upward and drives the upper push rod 63 to push the bent reinforcing bar upward, thus completing the bending of both ends of the reinforcing bar in one go.
