[0003] Straightening roller mechanism: It is the core component of the bar straightening machine, and generally has two rows of straightening rollers, the number of which varies.

[0004] Drive unit: Provides power for the rotation of the straightening roller, usually an electric motor connected to the active straightening roller through transmission components such as a reducer and coupling.

[0005] Control system: Used to control the overall operation of the straightening machine, including functions such as start-up, stop, speed adjustment, and pressure control.

[0006] Support and frame: They serve to support and fix the various components of the straightening machine, ensuring the stability and rigidity of the equipment.

[0007] Measuring devices: Some advanced bar straightening machines are also equipped with measuring devices, such as laser displacement sensors and photoelectric encoders, to measure the curvature or straightness of the bars in real time.

[0008] However, existing bar straightening machines have the following drawbacks: when straightening existing bars, they rely heavily on manual loading and unloading, which is relatively slow and requires frequent repetition of the bar loading and unloading action, which consumes a lot of time.

[0024] This application provides a bar straightening machine with a loading and unloading mechanism, which effectively solves the technical problem that existing bar straightening processes rely heavily on manual loading and unloading. Manual loading and unloading is relatively slow and requires frequent repetition of the bar loading and unloading action, consuming a significant amount of time. Especially in mass production, the speed of manual loading and unloading is difficult to keep up with the working rhythm of the straightening machine, thus limiting the efficiency of the entire production process. This device, through the cooperation of an adjusting plate 2, a rubber pad 22, and a connecting plate 3, allows for rapid loading and unloading of the bars by clamping and rotating the bars through the adjusting plate 2 during straightening. Its operating speed and rhythm can match the working frequency of the straightening machine, greatly reducing loading and unloading time and thus improving overall production efficiency.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that existing bar straightening processes rely heavily on manual loading and unloading, which is relatively slow and requires frequent repetition of bar loading and unloading actions, consuming a significant amount of time. Especially in mass production, the manual loading and unloading speed struggles to keep up with the straightening machine's pace, thus limiting the efficiency of the entire production process. The overall concept is as follows: A bar straightening machine with a loading and unloading mechanism includes a straightening device 1. The straightening device 1 is equipped with a feeding mechanism for loading and unloading bars. The feeding mechanism includes an adjusting plate 2 and a connecting plate 3. The device includes a connecting plate 3, a pull plate 4, and a placement groove 5. There are two adjusting plates 2 and two connecting plates 3. The two adjusting plates 2 are located on both sides of the straightening device 1. A first spring 35 and a telescopic rod 36 are fixedly installed between the two connecting plates 3 and the two adjusting plates 2. Each first spring 35 is located on the outer side wall of the telescopic rod 36. The pull plate 4 is located at the side end of the connecting plate 3. The placement groove 5 is fixedly installed at the side end of the straightening device 1. When the connecting plate 3 rotates to ninety degrees, the user can drive the two cylinders 21 to retract. At this time, the bar will fall into the placement groove 5. The user can place the next bar between the two rubber pads 22.

[0027] A straightening pressure head 11 is fixedly installed at the upper end of the straightening device 1. When the user straightens the bar, the user can place the bar on the straightening device 1, and the straightening device 1 will detect the bent part of the bar and drive the straightening pressure head 11 to straighten the bar.

[0028] Positioning rods 12 are fixedly installed on both ends of the straightening device 1. Four limiting grooves 13 are arrayed on the side end of one of the positioning rods 12. A first guide plate 14 is fixedly installed on the upper end of the straightening device 1. Cylinders 21 are fixedly installed on the side ends of the two adjusting plates 2. Rubber pads 22 are fixedly installed on the side ends of the two cylinders 21. A second guide plate 23 is fixedly installed on the side ends of the two adjusting plates 2 facing each other. After the straightening of the bar is completed, the bar can be unloaded. The user can drive the cylinders 21 on both sides to extend. The extension of the cylinders 21 on both sides will drive the two rubber pads 22 to move closer to the sides of the bar. After the two cylinders 21 drive the two rubber pads 22 to clamp the bar, the straightened bar is fixed.

[0029] Both connecting plates 3 have mounting grooves 31 extending through their side ends. A damping bearing 32 is fixedly installed on the inner wall of one side of the mounting groove 31. The two connecting plates 3 are rotatably mounted on the circumferential ends of the two positioning rods 12 through the mounting grooves 31 and the damping bearings 32, respectively. L-shaped side plates 33 are fixedly installed on the opposite side ends of the two connecting plates 3. Movable grooves 34 are extending through the side ends of the two L-shaped side plates 33. The rotation of the connecting plates 3 drives the adjusting plate 2 to rotate. The rotation of the adjusting plate 2 drives the rod clamped by the side end of the rubber pad 22 to rotate. A second guide plate 23 is fixedly installed on the side end of the adjusting plate 2. When the adjusting plate 2 drives the second guide plate 23 to rotate and contact the first guide plate 14, since the ends of the first guide plate 14 and the second guide plate 23 are both beveled, the adjusting plate 2 will gradually move upward, thereby driving the rod clamped by the side end of the adjusting plate 2 to move upward and leave the slot.

[0030] Two limiting rods 42 are fixedly installed on the side end of the pull plate 4. The two limiting rods 42 are slidably installed on the inner side wall of the two movable grooves 34 respectively. The ends of the two limiting rods 42 are located on the inner side wall of the limiting groove 13. A second spring 41 is fixedly installed between the pull plate 4 and the L-shaped side plate 33. The user can pull the pull plate 4. The movement of the pull plate 4 causes the two limiting rods 42 to move away from the inner side wall of the limiting groove 13. At this time, the second spring 41 is stretched. The user can rotate the pull plate 4. The rotation of the pull plate 4 causes the connecting plate 3 to rotate at the circumferential end of the positioning rod 12.

[0031] To address the problems existing in the prior art, this utility model provides a bar straightening machine with a loading and unloading mechanism. This device, through the cooperation of an adjusting plate 2, a rubber pad 22 and a connecting plate 3, allows for the loading and unloading of bars by clamping and rotating the bars through the adjusting plate 2 during bar straightening. Its operating speed and rhythm can be matched with the working frequency of the straightening machine, greatly reducing the loading and unloading time and thus improving the overall production efficiency.

[0032] Straightening device 1: It is used to detect the bent part of the bar and drive the straightening pressure head 11 to straighten the bar. It is the core equipment for bar straightening. It has material conveying mechanisms on both sides for loading and unloading the bar.

[0033] Straightening head 11: After the straightening equipment 1 detects the bent part of the bar, the straightening equipment 1 drives the bar to perform a straightening operation.

[0034] Positioning rod 12: Fixedly installed on both ends of the straightening equipment 1, used to install the connecting plate 3, so that the connecting plate 3 can rotate around its circumferential end.

[0035] Limiting groove 13: The array is opened at the side end of the positioning rod 12 on one side, and cooperates with the limiting rod 42 to limit the rotation position of the pull plate 4 and the connecting plate 3.

[0036] First guide plate 14: Fixedly installed at the upper end of the straightening equipment 1, and cooperates with the second guide plate 23 at the side end of the adjusting plate 2. When the adjusting plate 2 rotates, due to the effect of the inclined cut surfaces at the ends of the two, the adjusting plate 2 drives the bar to move upward and leave the slot.

[0037] Adjustment plate 2: There are two of them, located on both sides of the straightening equipment 1. They cooperate with cylinder 21 and rubber pad 22 to clamp the bar. After straightening, they rotate to realize the unloading and clamping positioning of the bar during loading. They are connected to the connecting plate 3 and rotated by it.

[0038] Cylinder 21: Fixedly installed on the side end of the adjusting plate 2, it drives the rubber pad 22 to move by extending and contracting, thereby clamping and releasing the rod.

[0039] Rubber pad 22: It is fixedly installed on the side end of the cylinder 21 and is used to directly contact and clamp the bar to avoid damaging the surface of the bar and ensure the stability of the clamping.

[0040] Second guide plate 23: Fixedly installed on the side end opposite to the adjusting plate 2, cooperating with the first guide plate 14, to realize the upward movement of the bar during the rotation of the adjusting plate 2.

[0041] Connecting plate 3: There are two of them. They are rotatably installed on the circumferential end of the positioning rod 12 through the mounting groove 31 and the damping bearing 32. They are connected to the adjusting plate 2. When they rotate, they drive the adjusting plate 2 to rotate, which in turn drives the bar to rotate, realizing the bar feeding and feeding actions. The side end is provided with an L-shaped side plate 33.

[0042] Mounting groove 31: It is formed at the side end of the connecting plate 3 and is used to install the damping bearing 32 to realize the rotational connection between the connecting plate 3 and the positioning rod 12.

[0043] Damping bearing 32: Installed on the inner side wall of mounting groove 31, so that connecting plate 3 can rotate smoothly relative to positioning rod 12.

[0044] L-shaped side plate 33: It is fixedly installed on the side end opposite to the connecting plate 3. A movable groove 34 is opened through the side end for installing the limiting rod 42, which cooperates with the pull plate 4 to limit the rotation position of the pull plate 4 and the connecting plate 3.

[0045] Movable groove 34: It is opened at the side end of the L-shaped side plate 33 and cooperates with the limiting rod 42 to allow the limiting rod 42 to slide in it. At the same time, it guides and limits the rotation of the pull plate 4 and the connecting plate 3.

[0046] First spring 35: There are two of them, located on the outer walls of the two telescopic rods 36 respectively, connecting the adjusting plate 2 and the connecting plate 3, and playing the role of buffering and resetting.

[0047] Telescopic rod 36: There are two of them. They cooperate with the first spring 35 to connect the adjusting plate 2 and the connecting plate 3. They play a guiding and supporting role when the adjusting plate 2 and the connecting plate 3 move relative to each other.

[0048] Pull plate 4: Located at the side end of the connecting plate 3, it can be pulled to move the limiting rod 42 away from the limiting groove 13, thereby realizing the rotation of the connecting plate 3, which in turn drives the adjusting plate 2 and the rod to rotate. The limiting rod 42 is fixedly installed at its side end.

[0049] The second spring 41 is fixedly installed between the pull plate 4 and the L-shaped side plate 33. It is stretched when the pull plate 4 is pulled, and the pull plate 4 and the connecting plate 3 can be reset when the external force disappears.

[0050] Limiting rod 42: It is fixedly installed on the side end of the pull plate 4 and slidably installed on the inner side wall of the movable groove 34. Its end can be located on the inner side wall of the limiting groove 13, which plays the role of limiting the rotation position of the pull plate 4 and the connecting plate 3.

[0051] Placement slot 5: Fixedly installed on the side end of the straightening equipment 1, used to receive the bar falling from the adjusting plate 2 when the bar is unloaded, and at the same time provide a position for placing new bars when loading.

[0052] Working principle:

[0053] When straightening the bar stock, the user can place the bar stock on the straightening device 1. The straightening device 1 detects the bent portion of the bar stock and drives the straightening pressure head 11 to straighten the bar stock. After the bar stock is straightened, it can be unloaded. The user can drive the cylinders 21 on both sides to extend. The extension of the cylinders 21 on both sides will drive the two rubber pads 22 to move closer to the sides of the bar stock. After the two cylinders 21 drive the two rubber pads 22 to clamp the bar stock, the straightened bar stock is fixed. The user can pull the pull plate 4. The movement of the pull plate 4 will drive the two limit rods 42 to move away. The inner wall of the limiting groove 13 is opened. At this time, the second spring 41 is stretched, and the user can rotate the pull plate 4. The rotation of the pull plate 4 causes the connecting plate 3 to rotate at the circumferential end of the positioning rod 12. The rotation of the connecting plate 3 causes the adjusting plate 2 to rotate. The rotation of the adjusting plate 2 causes the rod clamped at the side end of the rubber pad 22 to rotate. A second guide plate 23 is fixedly installed at the side end of the adjusting plate 2. When the adjusting plate 2 drives the second guide plate 23 to rotate and contact the first guide plate 14, since the ends of the first guide plate 14 and the second guide plate 23 are both beveled, the adjusting plate 2 will gradually move upward, thereby causing the rod clamped at the side end of the adjusting plate 2 to move upward. The rod moves out of the slot. When the connecting plate 3 rotates 90 degrees, the user can drive the two cylinders 21 to retract, at which point the rod will fall into the placement slot 5. The user can then place the next rod between the two rubber pads 22, clamp it again, and rotate it back to load the next rod. This process is repeated to load and unload the rods. When straightening existing rods, manual loading and unloading are often required. Manual loading and unloading is relatively slow and requires frequent repetition of the rod loading and unloading action, which consumes a lot of time. Especially in mass production, the speed of manual loading and unloading is difficult to keep up with the working rhythm of the straightening machine. This limits the efficiency of the entire production process. This device, through the coordination of adjusting plate 2, rubber pad 22 and connecting plate 3, allows for the quick loading and unloading of bars by clamping and rotating the bars through adjusting plate 2 during bar straightening. Its operating speed and rhythm can match the working frequency of the straightening machine, greatly reducing the loading and unloading time and thus improving the overall production efficiency. When feeding bars, this device feeds them by clamping both ends of the bars without contacting the circumferential ends, avoiding re-deformation of the straightened bars and ensuring the straightening effect of the bars while feeding them.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
