Description

Technical Field

[0001] This utility model belongs to the field of steel bar bending technology, specifically, it relates to an automatic feeding steel bar bending device for building construction. Background Technology

[0002] Steel bars for construction refer to steel reinforcement materials specifically used in building engineering. They are mainly used to reinforce and strengthen concrete structures such as columns, beams, slabs, and walls. Steel bars play a crucial role in building engineering. By embedding steel bars into concrete, the tensile strength and seismic resistance of the structure can be significantly improved.

[0003] In the construction industry, steel bars are a crucial building material, and their processing quality and efficiency directly affect the progress and quality of the entire project. Steel bar bending is a vital step in the steel bar processing, used to bend straight steel bars into specific shapes to meet the needs of different parts of the building structure. With the rapid development of the construction industry, higher demands are being placed on the efficiency, precision, and safety of steel bar bending operations. However, existing steel bar bending machines have significant shortcomings in terms of automation, especially in the feeding stage, which still heavily relies on manual operation. This has become a key factor restricting the overall efficiency and quality improvement of steel bar bending operations.

[0004] Chinese patent application number CN219402107U discloses an auxiliary feeding device for a rebar bending machine, including a bending machine and a roller conveyor. The bending machine and the roller conveyor are arranged side by side. A bending disc is rotatably mounted at the top center of the bending machine, and a central shaft is mounted at the top center of the bending disc. A bending pressure shaft is mounted on one side of the central shaft. In this invention, by using the bending machine, roller conveyor, and feeding mechanism in combination, when the rebar is placed on the rollers of the roller conveyor for conveying, the conveying rollers contact the rebar. During the rebar conveying process, multiple conveying rollers roll sequentially on both sides of the rebar. While the conveying rollers are rolling, the multiple conveying rollers on both sides clamp and convey the rebar, and at the same time, provide a stable horizontal force, so that the rebar feeding operation is smooth, and the rebar can accurately enter between the central shaft and the bending pressure shaft for bending, thereby improving production efficiency, reducing the labor intensity of workers, and ensuring the production efficiency of rebar bending.

[0005] However, in this application, the steel bars are first conveyed by conveyor rollers, but only one bar can be placed between the conveyor rollers at a time. Each steel bar still needs to be manually placed between the conveyor rollers, which makes the labor intensity of workers very high. In addition, after the steel bars are bent, they also need to be manually removed, which increases the labor intensity and reduces the bending efficiency. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0011] An extension cylinder is fixedly installed on the upper end of the limit bracket.

[0012] The following are further optimizations of the above technical solution by this utility model:

[0028] like Figure 1-3As shown: A steel bar bending device with automatic feeding for building construction includes a bending machine device 1, a feeding device 2 is provided on one side of the bending machine device 1 in the length direction, a mechanical arm 3 is provided on one side of the bending machine device 1 in the width direction, and a material picking component 4 is fixedly installed on the power output end of the mechanical arm 3.

[0029] The feeding device 2 includes a base plate 21, a sliding plate 25 is slidably installed on the base plate 21, and two sets of symmetrically spaced steel bar placement components 26 are detachably installed on the sliding plate 25. The two sets of steel bar placement components 26 are arranged along the length of the sliding plate 25.

[0030] A limit bracket 27 is fixedly installed at one end of the two sets of rebar placement components 26 away from the bending machine device 1, and a rebar 5 is placed between the two sets of rebar placement components 26;

[0031] An extension cylinder 29 is fixedly installed on the upper end of the limit bracket 27.

[0032] like Figure 1 As shown, the bending machine device 1 has the same structure and working principle as the GW55 steel bar bending machine produced by Xuchang Jingrui Machinery Manufacturing Co., Ltd.

[0033] The bending machine device 1 includes a body 11, and each of the four corners of the bottom surface of the body 11 is fixedly equipped with a first universal wheel 10 to facilitate the movement and adjustment of the bending machine device 1.

[0034] A bending disc 12 is rotatably mounted at the middle position of the upper end face of the body 11, and a central shaft 13 is vertically arranged at the middle position of the bending disc 12.

[0035] The bending disc 12 is provided with a number of evenly spaced mounting holes 15 near the central shaft 13. A bending shaft 14 can be detachably installed on the mounting holes 15 as needed.

[0036] Positioning plates 16 are fixedly installed on both sides of the bending disc 12 along the length of the machine body 11. Multiple evenly spaced limiting holes 17 are provided on the positioning plates 16. A stop shaft 18 can be detachably installed on the limiting holes 17 as needed.

[0037] Two guide conveyor wheels 19 are rotatably installed on the machine body 11 near the feeding device 2. The two guide conveyor wheels 19 rotate in opposite directions, which can convey the steel bars 5 to the bending disc 12.

[0038] The machine body 11 is equipped with a control system that controls the bending machine device 1 to perform bending operations. Its specific control principle is the same as that of the GW55 steel bar bending machine, and will not be described in detail here.

[0039] like Figure 2As shown, the bottom of the base plate 21 is fixedly installed with second universal wheels 210 at the four corners, which facilitates the adjustment of the position of the feeding device 2 and ensures that the steel bars 5 can be transported to the bending machine device 1 for bending.

[0040] In this embodiment, both the first universal wheel 10 and the second universal wheel 210 are universal wheels with self-locking function, which can be obtained commercially. Their self-locking principle is common knowledge and will not be described in detail here.

[0041] The base plate 21 has four sliding columns 23 arranged in a square array near the edge at the upper end, and each of the four sliding columns 23 is slidably mounted with a bearing 24.

[0042] The sliding plate 25 is fixedly installed on the mounting surface of the four bearings 24. With this design, the sliding plate 25 can slide up and down as the bearings 24 slide up and down.

[0043] The sliding plate 25 has two elongated holes 250 arranged symmetrically at intervals, and the two elongated holes 250 are arranged along the width direction of the sliding plate 25.

[0044] The two ends of the two sets of rebar placement components 26 are detachably installed in the corresponding elongated holes 250 by bolts. This design allows the spacing between the two sets of rebar placement components 26 to be adjusted at any time to accommodate different types of rebar 5 placed between the two sets of rebar placement components 26 for feeding.

[0045] An electric telescopic cylinder 22 is fixedly installed at the middle position of the base plate 21. The power output end of the electric telescopic cylinder 22 is fixedly installed with the sliding plate 25. With this design, the electric telescopic cylinder 22 can drive the sliding plate 25 to slide up and down.

[0046] The rebar placement assembly 26 includes an adjustment plate 260 that can be detachably installed on the elongated slot 250. The adjustment plate 260 has through holes at both ends, and the diameter of the through holes matches the size of the elongated slot 250. That is, the adjustment plate 260 can be detachably installed by matching the corresponding elongated slot 250 with the through holes, which facilitates adjustment.

[0047] The adjustment plate 260 has multiple uprights 261 arranged linearly. The multiple rows of uprights 261 on one adjustment plate 260 form a set of baffles. The steel bar 5 is placed between two sets of baffles.

[0048] In this embodiment, when using it, first adjust the spacing between the two sets of baffles to the diameter of the steel bar 5 to be bent, that is, place a row of steel bars 5 to be bent from bottom to top between the two sets of baffles.

[0049] A limiting bracket 27 is fixedly installed on the sliding plate 25 at one end of the two sets of steel bar placement components 26 away from the bending machine device 1. The end of the row of steel bars 5 to be bent away from the bending machine device 1 contacts the limiting bracket 27, which ensures that the row of steel bars 5 is neatly arranged from bottom to top.

[0050] An L-shaped plate 28 is adjustablely installed on the upper end of the limiting bracket 27 away from the rebar placement component 26. An extension cylinder 29 is fixedly installed on the L-shaped plate 28. With this design, the extension cylinder 29 can be adjusted up and down on the limiting bracket 27.

[0051] The power output end of the extension cylinder 29 faces the side of the reinforcing bar 5. In the initial state, the power output end of the extension cylinder 29 is flush with the end face of the limiting bracket 27 near the reinforcing bar 5.

[0052] In use, place one steel bar 5 between two sets of baffles, adjust the spacing between the two sets of baffles so that the spacing is the same as the outer diameter of the steel bar 5, and then place the remaining steel bars 5 from bottom to top between the two sets of baffles, ensuring that the end of this row of steel bars 5 away from the bending machine device 1 is in contact with and aligned with the limit bracket 27. Adjust the up and down position of the extension cylinder 29 to ensure that the power output end of the extension cylinder 29 is in contact with the end of the uppermost steel bar 5.

[0053] The position of the overall moving feeding device 2 is ensured that the other end of the uppermost steel bar 5 is between the two guide conveying wheels 19. During feeding, the extension cylinder 29 is activated, and the power output end of the extension cylinder 29 extends, pushing the uppermost steel bar 5 towards the bending machine device 1, so that the steel bar 5 enters between the two guide conveying wheels 19, completing the conveying of one steel bar 5. Then, the electric telescopic cylinder 22 is activated to extend upward, and the extension distance is the diameter of the steel bar 5. This drives the sliding plate 25 and the remaining steel bars 5 to move upward by the diameter of one steel bar 5, ensuring that one end of the next steel bar 5 contacts the power output end of the extension cylinder 29, facilitating its ejection and conveying.

[0054] like Figure 3 The material handling component 4 includes a cylinder mounting plate 41 fixedly installed at the power output end of the robotic arm 3.

[0055] A clamping cylinder 42 is fixedly installed on the other side of the cylinder mounting plate 41. In this embodiment, the clamping cylinder 42 is selected from the HFT series of standard cylinders and has two power output ends to realize the clamping action.

[0056] Each of the power output ends of the clamping cylinder 42 is fixedly equipped with a clamp 43. The two clamps 43 are arranged symmetrically. When the clamping cylinder 42 clamps, the lower ends of the two clamps 43 can contact and tighten together.

[0057] A linear array of anti-slip grooves 44 is provided at the lower end of the two clamps 43 that are close to each other to increase friction. After the steel bar 5 is bent, the robotic arm 3 drives the clamping cylinder 42 of the material picking component 4 to open and move to the position of the bent steel bar 5. The clamping cylinder 42 is controlled to clamp the steel bar 5, and the steel bar 5 is removed and placed in the designated area before the next steel bar 5 is bent.

[0058] In this embodiment, the robotic arm 3 is selected from the RM65 series of ABB. The control end of the robotic arm 3 is electrically connected to the control system. The control end of the electric telescopic cylinder 22 is electrically connected to the control system. The control ends of the clamping cylinder 42 and the extension cylinder 29 are respectively electrically connected to the control system through solenoid valves. The connection method is known in the prior art and will not be described in detail here.

[0059] The power output end of the electric telescopic cylinder 22 is driven by a motor to extend upward at a certain distance. It is commercially available. The specific principle of controlling the stroke is well known and will not be elaborated here.

[0060] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
