Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a multifunctional steel bar bending device, and belongs to the technical field of building construction. Background Art

[0002] Generally speaking, in some building lightning protection projects, galvanized flat steel or round steel is often used in distribution boxes, roofs, etc. as grounding trunk lines and lightning strips. When turning along the building shape, the round steel must be bent. Because larger-sized round steel has a higher hardness, it is difficult to bend it. Traditional construction uses the method of cutting at the turning point and then re-welding the connection. This greatly increases the lightning resistance, construction costs and the quality of the finished appearance. Especially in the lightning protection construction of complex buildings using galvanized round steel as lightning strips, all turns are connected by welding, which requires a huge amount of welding work. At the same time, the overlap of the flat steel increases the overlapping height of the lightning strip, affecting the appearance of the building.

[0003] Therefore, in many construction processes, during the lightning protection and grounding operations of buildings, it is necessary to bend the steel bars to ensure the grounding quality and aesthetic effect. For convenience, when bending the steel bars, pliers or other tools are often used to bend the steel bars manually. Due to the poor precision of manual processing, the bending deformation arc will produce different arc deformations due to different force magnitudes. It is often the case that the bending angle of the steel bar does not meet the requirements or there are large errors in the bending position. Not only is the bending efficiency low, but the bending effect is not ideal and affects the use. This method wastes manpower and financial resources, and the quality often does not meet the requirements.

[0004] In summary, the above traditional steel bar bending devices may have the following disadvantages in practical applications:

[0005] One is rigidity limitations: the rigidity of the rebar bending equipment may be limited, making it unable to adapt to the bending requirements of rebar of a specific shape or size. Some complex shapes of rebar may require other special processing equipment or manual operation to complete.

[0006] Second, limited adaptability: Rebar bending equipment is typically designed and manufactured for specific sizes and shapes, limiting its adaptability. When processing multiple sizes of rebar, components such as fixtures and molds may need to be replaced or adjusted, increasing operational complexity and time costs.

[0007] The third issue is low production efficiency: Since the steel bar bending device usually completes the bending process of one steel bar at a time, it may take a long time and human resources to process large quantities of steel bars. This may affect production efficiency and capacity.

[0008] Fourth, the operation requirements are high: using a steel bar bending device for steel bar bending requires experienced operators who need to be familiar with the equipment's operating procedures, parameter settings, and safety precautions. For beginners or operators who are not familiar with the equipment, a longer learning and adaptation period may be required.

[0009] Fifth, the equipment cost is high: Steel bar bending equipment is usually specialized equipment, and its manufacturing and purchase costs are relatively high. This may put a certain financial pressure on small-scale steel bar processing companies or individual craftsmen.

[0010] In short, the steel bar bending device has its advantages in the field of steel bar processing, but it also has some disadvantages. When choosing to use this equipment, it is necessary to comprehensively consider factors such as production needs, cost investment and technical requirements.

[0011] At present, a Chinese utility model patent with announcement number CN214768036U discloses an improved round steel bending device, comprising a base (1), a support column (2), a steel bar processing component (3) and a driving device (4), characterized in that: support columns (2) are symmetrically arranged above the base (1), and steel bar processing components (3) are vertically arranged on the tops of the two support columns (2), a hollow area (31) is opened in the middle of the steel bar processing component (3), and limit members (5) are symmetrically arranged on both sides above the hollow area (31), and the limit members (5) and the hollow area (31) form a forming area for round steel processing; a driving device (4) is placed directly below the hollow area (31), and the driving device (4) is detachably connected to the base (1) through a bolt assembly (6); and ring-shaped lifting ears (32) are also symmetrically arranged on both sides of the top of the steel bar processing component (3). Although the round steel bending device of this structure can realize the bending of round steel, it can only bend one steel bar at a time during the bending process, and cannot bend multiple steel bars at one time, resulting in low bending efficiency and bending errors, which is time-consuming and labor-intensive, and increases the labor intensity of operators. Moreover, since only one steel bar can be bent at a time, there will be large differences in the multiple steel bars after bending, and the processing quality and accuracy cannot be guaranteed. In short, it is often very inconvenient.

[0012] Therefore, the key to solving the above technical problems is to develop a multifunctional steel bar bending device with high steel bar bending efficiency and high precision. Summary of the Invention

[0053] The working principle is: before using a multifunctional steel bar bending device of the above-mentioned design structure, the completed device needs to be transported to the designated work location by manual labor or corresponding transport equipment to be installed as a spare part.

[0054] The specific installation steps are:

[0055] First, the operator uses a bending head (4) adapted to the curvature of the steel bar to be bent as required, and connects the bending head (4) to the working end of the electric telescopic device (32) to lock and fix it;

[0056] Then, the operator slides and engages each placement device (2) into the corresponding slide groove (11);

[0060] The specific steps are:

[0061] When in use, the operator first opens the brake device on the moving wheel (8) to open it, and then moves the device to the site where processing is required via the moving wheel (8) provided at the bottom of the device;

[0062] Then, the operator fixes the brake device of the moving wheel (8) so that the device is in a braking state;

[0063] Then, the operator adjusts the distance between the two placing racks (21) according to the required bending arc and distance.

[0110] An operating table 1, on which slide grooves 11 are symmetrically provided;

[0111] The placing devices 2 are slidably mounted in the corresponding chute 11;

[0112] The transmission device 3 is vertically connected to the operating table 1 and is located in front of the middle position of the two chutes 11;

[0116] In the present invention, the operating table 1 is used to support and fix other components to ensure the smooth operation of the entire device.

[0117] Further, such as Figure 5 and Figure 10 as well as Figure 11 As shown, the placing device 2 includes:

[0118] A display rack 21, wherein a locking groove 211 is provided on one end surface of the display rack 21;

[0119] A locking plate 22 , which is detachably mounted on the locking groove 211 ;

[0120] A locking assembly 23 connected to an opening of a locking slot 211 of the display rack 21;

[0121] The rack 21 has a plurality of placement holes 212 formed thereon in sequence from top to bottom for placing the steel bars 10 .

[0122] Specifically, such as Figure 5 As shown, the display rack 21 is a P-shaped structure as a whole, and a locking plate 24 is connected to the lower part of the display rack 21. Connection parts that are adapted to be snapped into the slide groove 11 are provided on both sides of the locking plate 24, wherein a tightening member 25 is also threadedly connected to the locking plate 24.

[0123] More specifically, Figure 11 As shown, the locking groove 211 is provided with a plurality of locking plate connecting holes for connecting the locking plate 22;

[0124] One end surface of the locking plate 22 is provided with arc-shaped locking openings that correspond to the placement holes 212 in sequence from top to bottom, and a plurality of locking plate connecting columns are also provided on the locking plate 22;

[0128] The locking member 233 is rotatably connected to the middle portion of the locking connecting shaft 232 , and the locking portion of the locking member 233 is elliptical in shape as a whole.

[0129] In the present invention, the locking piece 233 is rotated to drive the locking plate 22 to lock and loosen. When the locking handle of the locking piece 233 is in a vertical state, the locking plate 22 and the locking groove 211 are in a loose state; when the locking handle of the locking piece 233 is in a horizontal state, the locking plate 22 and the locking groove 211 are in a locked state, that is, tightly connected; the contact end surface of the locking plate 22 and the placement hole 212 is made of elastic material, or a rubber protective pad is connected to the contact end surface of the locking plate 22 and the placement hole 212.

[0136] Further, such as Figure 1 As shown, the cross section of the elbow 4 is D-shaped, and a locking mounting column adapted to the working end of the electric telescopic device 32 is provided in the middle of the non-arc surface of the elbow 4.

[0137] Before using the multifunctional steel bar bending device of the above-mentioned design structure, the completed device needs to be transported to a designated working position by manual labor or corresponding transport equipment to be installed as a standby.

[0138] The specific installation steps are:

[0139] First, the operator uses a bending head 4 adapted to the curvature of the steel bar to be bent as needed, and connects the bending head 4 to the working end of the electric telescopic device 32 for locking and fixing;

[0140] Then, the operator slides each placement device 2 into the corresponding slide slot 11;

[0141] Next, the operator releases the locking plates 24 and the locking members 233;

[0142] Then, the operator fixes the transmission device 3 and the control device 5 on the operating table 1 respectively, and then the devices can be used.

[0143] The specific steps are:

[0144] When in use, the operator first moves or transports the device to the site where processing is required;

[0145] Then, the operator adjusts the distance between the two racks 21 according to the required bending arc and distance. When adjusting the distance, the operator can operate and adjust according to the scale lines set on the outside of the chute 11, so that the distance between the two racks 21 and the central axis is consistent, thereby improving the quality of the bent product. After the distance between the two racks 21 is adjusted, the distance is fixed by the tightening piece 25 under each rack 21.

[0146] Then, the operator inserts the steel bars 10 into the placement holes 212 in sequence, so that the steel bars 10 span the two placement racks 21;

[0147] Next, the operator rotates the locking members 233 to lock and secure the steel bars 10 on the rack 21.

[0148] Finally, the operator loosens the tightening parts 25 respectively, fine-tunes the two display racks 21, and starts the control device 5. The control device 5 drives the electric telescopic device 32 to move toward the steel bars 10, and then drives the bending head 4 connected to the electric telescopic device 32 to bend the steel bars 10 between the two display racks 21. After the bending work is completed, after moving the display device 2 at one end, the several bent steel bars 10 on the device can be collected, and the bending work of the steel bars is completed.

[0149] Repeat the above steps in sequence until all the steel bars that need to be bent are completed.
