Technical Field
[0001] This utility model relates to the field of steel bar bending technology, specifically a steel bar bending machine. Background Technology
[0002] Some construction sites require bending of reinforcing bars, which necessitates the use of a reinforcing bar bending machine. Bending machines typically have two sets of bending rollers on a rotating disc, one in the center and the other on the side. The reinforcing bar is placed between these rollers, and bending is achieved by rotating the disc. However, in actual operation, after bending, the reinforcing bar must be manually lifted to remove it from between the rollers before it can be unloaded. Furthermore, the lifting must be done vertically; otherwise, unloading becomes difficult. When the reinforcing bar is heavy, lifting becomes strenuous. Therefore, a reinforcing bar bending machine is proposed to address these issues. Utility Model Content
[0003] The purpose of this utility model is to provide a rebar bending machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a rebar bending machine, comprising a bending machine, a manual bending device, and an automatic bending device;
[0005] The bending machine is equipped with a manual bending device and an automatic bending device. The automatic bending device has a limiting mechanism fixedly connected to the bending machine on one side. The automatic bending device is also equipped with a bending force application component for bending action. The automatic bending device is equipped with an automatic feeding mechanism for convenient material discharge.
[0006] The bending machine is also equipped with a handle on its side;
[0007] The automatic feeding mechanism includes a fixed frame, a cylinder device, and a sliding plate. The fixed frame is fixedly connected to the automatic bending device on the outside. The cylinder device is fixedly connected inside the fixed frame. The sliding plate is fixedly connected to the top of the cylinder device. The connecting plate is fixedly connected to the top of the sliding plate. The connecting plate is fixedly connected to the top plate. A rubber plate is fixedly connected above the top plate.
[0008] Some construction sites require bending of reinforcing bars, necessitating the use of a reinforcing bar bending machine. Bending machines typically have two sets of bending rollers on a rotating disc, one in the center and the other on the side. The reinforcing bar is placed between these rollers, and bending is achieved by rotating the disc. However, in practice, after bending, the reinforcing bar must be manually lifted to release it from between the rollers before it can be removed. This lifting must be done vertically; otherwise, unloading is difficult. When the reinforcing bar is heavy, lifting becomes strenuous. Automatic bending machines, powered by an external power source, incorporate an automatic unloading mechanism. A cylinder moves a sliding plate, which in turn moves a connecting plate, which in turn moves a top plate. A rubber plate above the top plate vertically lifts the bent reinforcing bar, allowing workers to directly remove it without manually lifting it, thus saving effort.
[0009] Furthermore, the limiting mechanism includes a fixed column, an adjusting plate, and a baffle. The top of the fixed column is fixedly connected to the bending machine, the adjusting plate is slidably connected inside the fixed column, and the baffle is fixedly connected to one side of the adjusting plate.
[0010] Furthermore, the top of the adjusting plate is provided with evenly distributed threaded grooves, the top of the fixing column is equipped with a fixing screw, and the bottom of the fixing screw is spirally connected to the adjusting plate through the threaded grooves.
[0011] One side of the baffle is flat, and the other side of the reinforcing bar is in contact with it. This ensures stable compression of the reinforcing bar and prevents it from rotating. The adjustable plate and fixing screw can adjust the position of the baffle and expand its application range.
[0012] Furthermore, the bending force-applying component includes an insert rod, a bending column, and a wide column. The insert rod is inserted into the automatic bending equipment, and the top of the insert rod is fixedly connected to the bending column. The top of the bending column is fixedly connected to a limiting part, and the top of the limiting part is fixedly connected to the wide column.
[0013] Furthermore, the outer side of the limiting part is inclined.
[0014] During bending, a limiting part and a wide column are set above the bending column. At this time, the diameter of the limiting part and the wide column is larger than the diameter of the bending column. During bending, the limiting part and the wide column play a certain role in pressing down the steel bar, which can prevent the steel bar from bouncing up and separating from the working position to a certain extent, thus ensuring the stable bending of the steel bar.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. When this utility model is in use, an automatic feeding mechanism is set inside the automatic bending equipment. The sliding plate is driven to move by the cylinder, the sliding plate drives the connecting plate to move, the connecting plate drives the top plate to move upward, and the rubber plate above the top plate can lift the bent steel bar vertically upward. The worker can directly pull it out for feeding without having to lift the steel bar, which is more labor-saving.
[0017] 2. During bending, a limiting part and a wide column are set above the bending column. At this time, the diameter of the limiting part and the wide column is larger than the diameter of the bending column. During bending, the limiting part and the wide column play a certain role in pressing down the steel bar, which can prevent the steel bar from springing up and separating from the working position to a certain extent, thus ensuring the stable bending of the steel bar. One side of the baffle is set flat, and one side of the steel bar contacts it. This can ensure stable compression of the steel bar and prevent the steel bar from rotating with it. At the same time, the adjustment plate and fixing screw can adjust the position of the baffle and expand the application range. Attached Figure Description

[0023] 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.
[0024] Example 1: Please refer to Figure 1 and Figure 3 This utility model provides a technical solution:
[0025] A steel bar bending machine includes a bending machine 1, a manual bending device 2, and an automatic bending device 3;
[0026] The above-mentioned bending machine 1 is equipped with a manual bending device 2 and an automatic bending device 3. The automatic bending device 3 is provided with a limiting mechanism 4 fixedly connected to the bending machine 1 on one side. The above-mentioned automatic bending device 3 is also equipped with a bending force application component 6 for bending action. The automatic bending device 3 is equipped with an automatic unloading mechanism 5 for facilitating material discharge.
[0027] The bending machine 1 mentioned above is also equipped with a handle 7 on its side;
[0028] The aforementioned automatic feeding mechanism 5 includes a fixed frame 501, a cylinder device 502, and a sliding plate 503. The outer side of the fixed frame 501 is fixedly connected to the automatic bending device 3. The cylinder device 502 is fixedly connected inside the fixed frame 501. The sliding plate 503 is fixedly connected to the top of the cylinder device 502. The top of the sliding plate 503 is fixedly connected to the top of the sliding plate 503. The top of the connecting plate 504 is fixedly connected to the top of the connecting plate 504. A top plate 505 is fixedly connected above the top plate 505. A rubber plate 506 is fixedly connected above the top plate 505.
[0029] Some construction sites require bending of steel bars, which necessitates the use of a steel bar bending machine. A typical bending machine has two sets of bending rollers on a rotating disc, one in the center and the other on the side. The steel bar is placed between them, and bending is achieved by rotating the disc. However, in actual operation, after bending, the steel bar needs to be manually lifted to release it from between the two sets of bending rollers before it can be removed. Furthermore, the lifting must be vertical; otherwise, unloading is difficult. When the steel bar is heavy, lifting becomes strenuous. In this system, an external power supply is used. An automatic unloading mechanism 5 is installed inside the automatic bending equipment 3. A cylinder 502 moves a sliding plate 503, which in turn moves a connecting plate 504. The connecting plate 504 then moves a top plate 505 upwards. A rubber plate 506 above the top plate 505 vertically lifts the bent steel bar, allowing workers to directly remove it without manually lifting it, thus saving effort.
[0030] In this embodiment, the manual bending device 2 can be used to easily bend and correct small steel bars, while the automatic bending device 3 is provided with multiple grooves. At this time, the bending force application component 6 can be used to bend the steel bars, thus expanding the scope of application.
[0031] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 Specifically, the aforementioned limiting mechanism 4 includes a fixed column 401, an adjusting plate 402, and a baffle 403. The top of the fixed column 401 is fixedly connected to the bending machine 1. The adjusting plate 402 is slidably connected inside the fixed column 401. The baffle 403 is fixedly connected to one side of the adjusting plate 402.
[0032] The top of the aforementioned adjusting plate 402 is provided with evenly distributed threaded grooves, and the top of the aforementioned fixing column 401 is equipped with a fixing screw 404, and the bottom of the fixing screw 404 is spirally connected to the adjusting plate 402 through the threaded grooves.
[0033] One side of the baffle 403 is flat, and one side of the reinforcing bar is in contact with it. This ensures stable compression of the reinforcing bar and prevents the reinforcing bar from rotating with it. At the same time, the adjusting plate 402 and the fixing screw 404 can adjust the position of the baffle 403 and expand its application range.
[0034] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 4 Specifically, the bending force-applying component 6 includes an insert rod 601, a bending column 602, and a wide column 604. The insert rod 601 is inserted into the automatic bending device 3. The top of the insert rod 601 is fixedly connected to the bending column 602. The top of the bending column 602 is fixedly connected to a limiting part 603, and the top of the limiting part 603 is fixedly connected to the wide column 604.
[0035] The outer side of the aforementioned limiting part 603 is inclined.
[0036] During bending, a limiting part 603 and a wide column 604 are provided above the bending column 602. At this time, the diameter of the limiting part 603 and the wide column 604 is larger than the diameter of the bending column 602. During bending, the limiting part 603 and the wide column 604 play a certain role in pressing down the steel bar, which can prevent the steel bar from springing up and separating from the working position to a certain extent, thus ensuring the stable bending of the steel bar.
