[0001] This utility model relates to the field of metal product bending technology, and in particular to a metal product bending device. Background Technology

[0002] Metal bending is a forming process in cold working of metal products. It uses pressure equipment to bend flat or profiled metal parts into workpieces with specific angles and curvatures.

[0003] In the existing technology, when stamping and bending metal products, different stamping heads need to be changed to perform stamping and bending at different angles. The change process is cumbersome, time-consuming, and affects processing efficiency. Therefore, we propose a metal product bending device.

[0004] The existing patent (publication number: CN222385683U) is a metal product bending device. This utility model solves the problem of needing to replace the stamping bending head when the workpiece bending angle is different.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, some existing structures for bending metal sheets have limited bending angles, making it inconvenient to bend the metal sheets to smaller angles or fold them into a U-shape.

[0006] Therefore, a bending device for metal products is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a metal product bending device that can solve the problem that some existing structures for bending metal sheets have limited bending angles, making it inconvenient to bend metal sheets to a small angle or fold them into a U-shape.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a metal product bending device, comprising a base plate and a metal plate, wherein a side-push bending mechanism is provided on the front side of the top of the base plate, a bottom-push bending mechanism is provided on the bottom of the base plate, a pressure plate is provided on the top of the base plate, and the metal plate is located at the bottom of the pressure plate; the side-push bending mechanism comprises a first roller, two first electric telescopic rods, a fixing block, and an adjusting rod, wherein the first roller is rotatably connected between the rear sides of the two first electric telescopic rods, the fixing block is fixedly connected between the front sides of the two first electric telescopic rods, the adjusting rod is rotatably connected to the bottom of the fixing block, and the adjusting rod is threadedly connected to the inside of the base plate.

[0010] Preferably, the bottom-pushing bending mechanism includes a second roller, two second electric telescopic rods and a fixed frame. The bottom of the second electric telescopic rod is fixedly connected to the bottom of the inner wall of the fixed frame, the top of the fixed frame is fixedly connected to the bottom of the base plate, and the second roller is rotatably connected between the tops of the two second electric telescopic rods.

[0011] Preferably, the base plate has a through groove inside, and the second roller is located inside the through groove.

[0012] Preferably, a limiting frame is fixedly connected to the surface of the pressure plate, and a rotating rod is threadedly connected inside the limiting frame. The top of the rotating rod is rotatably connected to the bottom of the base plate.

[0013] Preferably, the bottom of the pressure plate is fixedly connected with an anti-slip cone, and the number of anti-slip cones is several and evenly distributed on the bottom of the pressure plate, with the bottom of the anti-slip cones contacting the top of the metal plate.

[0015] Preferably, both the pressure plate and the anti-slip cone are made of high-strength alloy steel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application sets up a side-pushing bending mechanism, which uses two first electric telescopic rods connected to an external power source and a synchronous controller to achieve synchronous leftward extension of the telescopic ends, driving the first roller connected to the rotation to move to the left, further bending the metal plate. The fixed block is connected to the front side of the two first electric telescopic rods, and the limiting rods on both sides of its bottom slide in the limiting holes of the bottom plate to ensure movement stability. Rotating the adjusting rod can drive the fixed block and the first roller to move up and down, adjusting the height of the first roller to the appropriate position, which makes it easy to bend the metal plate to less than 90 degrees or even fold it into a U-shape, realizing small angle and folding processing;

[0018] 2. This application sets up a bottom-push bending mechanism, with two second electric telescopic rods connected to an external power supply and a synchronous controller. The telescopic ends move upward synchronously, driving the second rollers connected to the rotatable parts to move upward. The second electric telescopic rods are fixed to the base plate by a fixing frame. The through groove of the base plate provides movement space for the second rollers, allowing them to pass through the through groove and push the metal plate to achieve a maximum bending of 90 degrees. This provides basic angle support for the initial bending of the metal plate and expands the bending angle range in conjunction with the side-push bending mechanism. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A metal product bending device includes a base plate 1 and a metal plate 3. A side-push bending mechanism 2 is provided on the front side of the top of the base plate 1, and a bottom-push bending mechanism 7 is provided on the bottom of the base plate 1. A pressure plate 4 is provided on the top of the base plate 1, and the metal plate 3 is located at the bottom of the pressure plate 4. The side-push bending mechanism 2 includes a first roller 201, two first electric telescopic rods 202, a fixing block 203, and an adjusting rod 204. The first roller 201 is rotatably connected between the rear sides of the two first electric telescopic rods 202, the fixing block 203 is fixedly connected between the front sides of the two first electric telescopic rods 202, and the adjusting rod 204 is rotatably connected to the bottom of the fixing block 203 and threadedly connected to the inside of the base plate 1.

[0029] In this embodiment: by placing the metal plate 3 at the bottom of the pressure plate 4 and keeping it parallel to the pressure plate 4, the four corner legs 5 of the base plate 1 provide stable support. By rotating the rotating rod 11, since the rotating rod 11 is threadedly connected to the limit frame 6 and its top is rotatably connected to the base plate 1, the pressure plate 4 is driven to move downward. Its bottom anti-slip cone 12 presses down on the metal plate 3, enhancing stability. By operating the bottom push bending mechanism 7, the metal plate 3 can be bent to ninety degrees. When a smaller angle is needed or when folding into a U-shape, the side push bending mechanism 2 is operated to make the first roller 201 move to the left. The metal plate 3 continues to bend under pressure. The bottom limiting rod 10 of the fixed block 203 slides within the limiting hole 9 to ensure stability. The height of the bottom of the first roller 201 is adjusted to the thickness of the pressure plate 4 plus the metal plate 3 by rotating the adjusting rod 204, which facilitates folding. The bottom pushing bending mechanism 7 and the side pushing bending mechanism 2 work together to achieve bending at any angle. This solves the problem that some existing structures for bending metal plates have limited bending angles and are not convenient for bending metal plates to a small angle or folding them into a U-shape.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom sides of the fixed block 203 are fixedly connected to limit rods 10, and the top sides of the base plate 1 are provided with limit holes 9, and the limit rods 10 are slidably connected inside the limit holes 9.

[0031] Specifically, such as Figure 4 As shown, the bottom-pushing bending mechanism 7 includes a second roller 701, two second electric telescopic rods 702 and a fixed frame 703. The bottom of the second electric telescopic rod 702 is fixedly connected to the bottom of the inner wall of the fixed frame 703, and the top of the fixed frame 703 is fixedly connected to the bottom of the base plate 1. The second roller 701 is rotatably connected between the tops of the two second electric telescopic rods 702.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, a through groove 8 is provided inside the base plate 1, and the second roller 701 is located inside the through groove 8.

[0033] In this embodiment: the bottom limiting rod 10 of the fixed block 203 is slidably connected to the limiting hole 9 of the bottom plate 1 to ensure the stable movement of the side push bending mechanism 2. The second electric telescopic rod 702 in the bottom push bending mechanism 7 is fixed by the fixed frame 703 and, together with the rotating second roller 701, can stably push the metal plate 3. The through groove 8 of the bottom plate 1 provides the second roller 701 with movement space to ensure that the bottom push bending process is smooth and accurate.

[0034] Specifically, such as Figure 1 and Figure 5 As shown, a limit frame 6 is fixedly connected to the surface of the pressure plate 4, and a rotating rod 11 is threadedly connected inside the limit frame 6. The top of the rotating rod 11 is rotatably connected to the bottom of the base plate 1.

[0035] Specifically, such as Figure 1 and Figure 6 As shown, anti-slip cones 12 are fixedly connected to the bottom of the pressure plate 4. There are several anti-slip cones 12, which are evenly distributed on the bottom of the pressure plate 4. The bottom of the anti-slip cones 12 is in contact with the top of the metal plate 3.

[0036] In this embodiment: the pressure plate 4 is threadedly connected to the rotating rod 11 through the limiting frame 6. The rotating rod 11 is rotatably engaged with the base plate 1, which facilitates the adjustment of the height of the pressure plate 4 to press and fix the metal plate 3. The anti-slip cones 12 evenly distributed at the bottom of the pressure plate 4 enhance the friction with the metal plate 3, prevent slippage when bending, and improve processing stability.

[0037] Specifically, such as Figure 1 As shown, support legs 5 are fixedly connected to the four corners of the bottom of the base plate 1.

[0038] Specifically, such as Figure 6 As shown, both the pressure plate 4 and the anti-slip cone 12 are made of high-strength alloy steel.

[0039] In this embodiment: the four corner legs 5 at the bottom of the base plate 1 provide stable support for the base plate 1 to prevent shaking during processing. The pressure plate 4 and the anti-slip cone 12 are made of high-strength alloy steel, which has high strength and is not easily deformed, ensuring the pressing effect and service life, and is suitable for the processing requirements of high-strength metal plate 3.

[0040] Working principle: The metal plate 3 to be bent is placed at the bottom of the pressure plate 4, making the metal plate 3 parallel to the pressure plate 4. Support legs 5 are fixedly connected to the four corners of the bottom of the base plate 1, providing stable support. Then, the rotating rod 11 is rotated. Since the rotating rod 11 is threaded inside the limiting frame 6 and its top is rotatably connected to the bottom of the base plate 1, and the limiting frame 6 is fixedly connected to the surface of the pressure plate 4, the rotation of the rotating rod 11 will cause the pressure plate 4 to move downwards. Several evenly distributed anti-slip cones 12 fixedly connected to the bottom of the pressure plate 4 move downwards accordingly and contact the top of the metal plate 3, pressing the metal plate 3. Both the pressure plate 4 and the anti-slip cones 12 are made of high-strength alloy steel, ensuring that they are not easily deformed during the pressing process and enhancing the pressing stability. Then, power is supplied to the two second electric telescopic rods 702 in the bottom-push bending mechanism 7 via an external power source, and their telescopic ends are simultaneously moved upward by an external synchronous controller. The bottom of the second electric telescopic rod 702 is fixedly connected to the bottom of the inner wall of the fixed frame 703, and the top of the fixed frame 703 is fixedly connected to the top of the base plate 1, so that the second roller 701 moves upward under the drive of the two second electric telescopic rods 702. A through groove 8 is opened inside the base plate 1, and the second roller 701 is located inside the through groove 8, so that the second roller 701 can pass through the through groove 8 to push and bend the metal plate 3. At this time, the bending angle can reach up to 90 degrees. If it is necessary to continue bending to less than 90 degrees, power is supplied to the two first electric telescopic rods 202 in the side-push bending mechanism 2 via an external power source. Electricity, also controlled by an external synchronous controller, extends the telescopic end to the left simultaneously. The first roller 201 is rotatably connected between the rear sides of the two first electric telescopic rods 202, thus moving the first roller 201 to the left to continue bending the metal plate 3. The fixing block 203 is fixedly connected between the front sides of the two first electric telescopic rods 202. The limiting rods 10 on both sides of the bottom of the fixing block 203 are slidably connected to the limiting holes 9 on both sides of the top of the base plate 1 to ensure the stability of the first electric telescopic rod 202 during movement. To bend the metal plate 3 into a U-shape, the adjusting rod 204 can be rotated. The adjusting rod 204 is rotatably connected to the bottom of the fixing block 203 and threaded into the inside of the base plate 1, driving the fixing block 203 to move upward, thereby adjusting the first roller 201. The bottom height of the wheel 201 is at the position where the thickness of the pressure plate 4 plus the thickness of the metal plate 3 is located, which facilitates the first roller 201 to move to the left to push the metal plate 3 to complete the folding. Through the cooperation of the bottom push bending mechanism 7 and the side push bending mechanism 2, the metal plate 3 can be bent to any angle. This solves the problem that some existing structures for bending metal plates have limited bending angles and are not convenient for bending metal plates to small angles or folding them into a U-shape. It should be noted that the first electric telescopic rod 202, the second electric telescopic rod 702 and the external controller are all existing and published mature technologies, and the contents not described in detail in this specification are all existing technologies known to those skilled in the art. The basic mechanisms are not elaborated here.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
