Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to an adjustable bending device for processing building steel bars. Background Technology

[0002] In the field of construction engineering, steel bars are frequently used. Sometimes, long steel bars are cut into multiple segments. After cutting, the shorter segments need to be bent, which requires a bending device. Existing bending devices have a relatively simple structure and poor adjustability. Most of them fix a fulcrum in the middle of the steel bar and then bend it by rotating both ends. However, this bending method can only bend the steel bar to an approximate angle. Subsequent manual bending adjustments are still required, which is time-consuming and labor-intensive. It is inconvenient to bend the steel bar to a specific angle, i.e., the required curvature, in one go, thus reducing the practicality of steel bar bending devices. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable bending device for processing building steel bars, which solves the problem that it is inconvenient to adjust the bending device when bending steel bars, and it is inconvenient to bend the steel bars to the required curvature in one go.

[0005] (II) Technical Solution

[0006] To facilitate the adjustment of the bending device during the bending of the aforementioned reinforcing bars, and to enable the reinforcing bars to bend to the required curvature in one go, this utility model provides the following technical solution: An adjustable bending device for processing building reinforcing bars, comprising a processing table, a guide groove provided on the left side of the upper surface of the processing table, a scale value provided at the end of the guide groove, an inner sliding pin slidably connected inside the guide groove, a fixed threaded sleeve installed on the left end of the upper surface of the processing table, an adjusting screw connected internally to the fixed threaded sleeve, a transition block rotatably connected to the right end of the adjusting screw via a bearing ring, a transition arm rotatably connected to the end face of the transition block, a first connecting block rotatably connected to the right end of the transition arm, and a first driven rod and a second driven rod installed on the end faces of the first connecting blocks on both the front and rear sides;

[0007] A hydraulic cylinder is installed on the right side of the upper surface of the processing table. An oil supply pipe is installed at the output end of the hydraulic cylinder. A hydraulic rod is installed at the left end of the oil supply pipe. A second connecting block is rotatably connected to the left end of the hydraulic rod. A first driving rod and a second driving rod are installed on the end faces of the second connecting block on both the front and rear sides. A first bending groove is formed on the right side surface of the first driven rod and the second driven rod. A second bending groove is formed on the left side surface of the first driving rod and the second driving rod. A steel bar body is movably connected inside the first bending groove and the second bending groove.

[0008] Preferably, both the first bending groove and the second bending groove are arc-shaped grooves and are adapted to the steel bar body.

[0009] Preferably, the first drive rod and the second drive rod are rotatably connected to the hydraulic rod via the second connecting block. One right end of the hydraulic rod is rotatably connected to the processing table via a pivot pin. The inner ends of the first drive rod and the second drive rod are rotatably connected to each other via pivot pins, and the pivot pins at this location are rotatably connected to the processing table.

[0010] Preferably, the inner ends of the first driven rod and the second driven rod are rotatably connected to each other by a pivot pin, and the pivot pin at this location is rotatably connected to the processing table.

[0011] Preferably, the guide groove is an arc-shaped groove, and the inner sliding pins on the front and rear sides are rotatably connected to the first driven rod and the second driven rod, respectively.

[0012] Preferably, the adapter arms on the front and rear sides are rotatably connected to the first driven rod and the second driven rod respectively via the first connecting block.

[0013] Compared with the prior art, this utility model provides an adjustable bending device for processing building steel bars, which has the following beneficial effects:

[0014] 1. The adjustable bending device for processing steel bars in this building can move the adapter block left and right by rotating the adjusting screw. The adapter block can also move the adapter arm, which in turn can cause the first driven rod and the second driven rod to rotate relative to each other. This allows the angle between the first driven rod and the second driven rod to be adjusted. The angle between the first driven rod and the second driven rod can be displayed more specifically through the scale value, so as to bend the steel bar body more accurately.

[0015] 2. The adjustable bending device for processing steel bars in this building operates by placing the steel bar body in the gap between the first driven rod and the second driven rod and the first driving rod and the second driving rod, and then driving the hydraulic cylinder. The hydraulic cylinder can drive the hydraulic rod to extend through the oil pipe, and then the hydraulic rod can drive the first driving rod and the second driving rod to rotate to one side of the first driven rod and the second driven rod. Therefore, as the first driving rod and the second driving rod approach the first driven rod and the second driven rod, the steel bar body on both the front and rear sides can be bent quickly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides an adjustable bending device for processing building steel bars, including a processing table 1. A guide groove 2 is provided on the left side of the upper surface of the processing table 1. A scale value 3 is provided at the end of the guide groove 2. An inner sliding pin 4 is slidably connected inside the guide groove 2. A fixed screw sleeve 5 is installed on the left end of the upper surface of the processing table 1. An adjusting screw 6 is threadedly connected inside the fixed screw sleeve 5. A transition block 7 is rotatably connected to the right end of the adjusting screw 6 through a bearing ring. A transition arm 8 is rotatably connected to the end face of the transition block 7. A first connecting block 9 is rotatably connected to the right end of the transition arm 8. A first driven rod 10 and a second driven rod 11 are installed on the end faces of the first connecting blocks 9 on the front and rear sides.

[0022] A hydraulic cylinder 12 is mounted on the right side of the upper surface of the processing table 1. An oil supply pipe 13 is installed at the output end of the hydraulic cylinder 12. A hydraulic rod 14 is installed at the left end of the oil supply pipe 13. A second connecting block 15 is rotatably connected to the left end of the hydraulic rod 14. A first drive rod 16 and a second drive rod 17 are mounted on the end faces of the second connecting blocks 15 on both the front and rear sides. A first bending groove 18 is formed on the right side surface of the first driven rod 10 and the second driven rod 11. A second bending groove 19 is formed on the left side surface of the first drive rod 16 and the second drive rod 17. The interiors of the first bending groove 18 and the second bending groove 19 are movably connected. The steel bar body 20 is attached. By placing the steel bar body 20 in the gap between the first driven rod 10 and the second driven rod 11 and the first driving rod 16 and the second driving rod 17, the hydraulic cylinder 12 is driven. The hydraulic cylinder 12 can drive the hydraulic rod 14 to extend through the oil supply pipe 13. In turn, the hydraulic rod 14 can drive the first driving rod 16 and the second driving rod 17 to rotate to one side of the first driven rod 10 and the second driven rod 11. Therefore, as the first driving rod 16 and the second driving rod 17 approach the first driven rod 10 and the second driven rod 11, the steel bar body 20 on both the front and rear sides can be quickly bent.

[0023] Furthermore, both the first bending groove 18 and the second bending groove 19 are arc-shaped grooves and are adapted to the steel bar body 20. When the steel bar body 20 is bent, it can be placed inside the first bending groove 18 and the second bending groove 19 to limit the movement of the steel bar body 20 and prevent it from moving during the bending process.

[0024] Furthermore, the first drive rod 16 and the second drive rod 17 are rotatably connected to the hydraulic rod 14 via the second connecting block 15. One right end of the hydraulic rod 14 is rotatably connected to the processing table 1 via a pivot pin. The inner ends of the first drive rod 16 and the second drive rod 17 are rotatably connected to each other via pivot pins, and the pivot pins at this point are rotatably connected to the processing table 1. When the hydraulic rod 14 pushes the first drive rod 16 and the second drive rod 17 to rotate, the hydraulic rod 14 itself can also rotate. Therefore, the first drive rod 16 and the second drive rod 17 can rotate simultaneously so as to bend the steel bar bodies 20 from both the front and rear sides.

[0025] Furthermore, the inner ends of the first driven rod 10 and the second driven rod 11 are rotatably connected to each other by a pivot pin, and the pivot pin is rotatably connected to the processing table 1. By rotating the adjusting screw 6, the adapter block 7 can be moved left and right, and the adapter block 7 can be moved to move the adapter arm 8. In turn, the adapter arm 8 can drive the first driven rod 10 and the second driven rod 11 to rotate relative to each other, thereby adjusting the included angle between the first driven rod 10 and the second driven rod 11. The included angle of the first driven rod 10 and the second driven rod 11 can be displayed more specifically by the scale value 3, so as to bend the steel bar body 20 more accurately.

[0026] Furthermore, the guide groove 2 is an arc-shaped groove, and the inner sliding pins 4 on the front and rear sides are rotatably connected to the first driven rod 10 and the second driven rod 11 respectively, so that the first driven rod 10 and the second driven rod 11 can be guided by the inner sliding pins 4 to make them rotate more stably.

[0027] Furthermore, the front and rear adapter arms 8 are rotatably connected to the first driven rod 10 and the second driven rod 11 respectively through the first connecting block 9, so that the adapter arms 8 can simultaneously drive the first driven rod 10 and the second driven rod 11 to rotate through the first connecting block 9, thereby adjusting the included angle between the first driven rod 10 and the second driven rod 11.

[0028] In use, rotating the adjusting screw 6 moves the adapter block 7 left and right, and the adapter block 7 moves the adapter arm 8. The adapter arm 8 then rotates the first driven rod 10 and the second driven rod 11 relative to each other, adjusting the angle between them. The angle between the first driven rod 10 and the second driven rod 11 is displayed precisely on the scale 3, allowing for more accurate bending of the reinforcing bar body 20. After fixing the first driven rod 10 and the second driven rod 11, the reinforcing bar body... The steel bar body 20 is placed in the gap between the first driven rod 10 and the second driven rod 11 and the first driving rod 16 and the second driving rod 17. Then, the hydraulic cylinder 12 is driven. The hydraulic cylinder 12 can drive the hydraulic rod 14 to extend through the oil supply pipe 13. In turn, the hydraulic rod 14 can drive the first driving rod 16 and the second driving rod 17 to rotate to one side of the first driven rod 10 and the second driven rod 11. Therefore, as the first driving rod 16 and the second driving rod 17 approach the first driven rod 10 and the second driven rod 11, the steel bar body 20 on both the front and rear sides can be quickly bent.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
