Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine. Background Technology
[0002] A bending machine is a mechanical device used to plastically deform metal sheets, strips, tubes or other metal profiles by applying pressure, thereby forming them into specific angles and shapes.
[0003] In the prior art, such as CN214813828U, a bending machine is disclosed. The key technical points of the solution are: it includes a frame, an upper die assembly mounted on the frame, a worktable positioned below the frame, and several lower bending dies of different lengths. A sliding groove is provided on the upper surface of the worktable in a horizontal direction, located directly below the upper die assembly. Sliding strips are fixedly mounted on the bottom of each of the lower bending dies, and these strips are slidably accommodated within the sliding grooves. A clamping assembly for clamping the sliding strips is also provided on the worktable. This invention has the advantage of allowing the removal of any lower bending die without removing other lower bending dies, thus improving the efficiency of loading and unloading lower bending dies.
[0004] To address the current issues with feeding materials to bending machines, especially when bending large sheets, existing equipment requires operators to use both hands to support the sheet and assist the bending machine. Prolonged operation can lead to muscle strain in the arms and lower back, increasing physical strain. Furthermore, hand tremors or uneven force while manually supporting the sheet can affect its positioning accuracy, resulting in bending angle deviations. Additionally, the significant effort required to maintain sheet stability hinders efficient operation of the bending machine, reducing overall production efficiency. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies in bending thin plates. When the size of the object is too large, workers need to support the plate with both hands while operating the bending machine. Prolonged operation can easily lead to muscle strain in the arms and waist, increasing physical burden. Furthermore, hand tremors or uneven force when manually supporting the plate can affect the positioning accuracy, resulting in bending angle deviations. Additionally, maintaining the stability of the plate requires significant effort, making it difficult to efficiently coordinate with the bending machine operation and reducing overall production efficiency. Therefore, this invention proposes a bending machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bending machine, comprising a main body, a bending module, a lower die base, and an auxiliary device. The bending module is disposed on the surface of the main body, and the lower die base is fixedly connected to the surface of the main body. The main body is provided with a mounting block and a groove. The mounting block is fixedly disposed on the surface of the main body, and the groove is formed on the surface of the main body. A rotating shaft is rotatably connected to the inner wall of the mounting block. An auxiliary device is disposed on the surface of the rotating shaft. The auxiliary device includes a support block and a roller. The support block is rotatably connected to the surface of the rotating shaft, and the roller is located on the inner wall of the support block. A stabilizing spring is sleeved and connected to the surface of a sliding rod, and a rotating handle is disposed below a fixed block.
[0007] Furthermore, a sliding rod is fixedly connected to the inner wall of the groove, a stabilizing spring is fixedly connected to the inner wall of the groove, and a slider is fixedly connected to the end of the stabilizing spring away from the groove.
[0008] Furthermore, the surfaces of the slider and the slide rod are slidably connected, the surface of the slider is fixedly connected to a hinge seat, and the inner wall of the hinge seat is rotatably connected to a support rod. The number of support rods is two sets and they are arranged symmetrically.
[0009] Furthermore, the surface of the support block is rotatably connected to a second rotating shaft, and there are two sets of the second rotating shafts arranged symmetrically. The end of the support rod away from the hinge seat is rotatably connected to the surface of the second rotating shaft.
[0010] Furthermore, the surface of the support block is fixedly connected with six sets of fixing blocks.
[0011] Furthermore, the surface of the fixing block is fixedly connected with guide rods, and there are four sets of guide rods. The surface of the support block is provided with guide grooves.
[0012] Furthermore, a rotating rod is slidably connected to the inner wall of the guide groove, and rollers are rotatably connected to the surface of the rotating rod. There are three sets of rollers, and a connecting rod is fixedly connected to the surface of the rotating rod.
[0013] Furthermore, a screw is rotatably connected to the surface of the fixing block, and the screw is threaded to the inner wall of the connecting rod. A handle is fixedly connected to the surface of the screw.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, by setting an auxiliary device, the lower mold base is more convenient to use when placing the object to be bent stably. By rotating the handles on both sides of the support block, the handles drive the connecting rod to adjust the height, so that the connecting rod slides stably in the vertical direction along the surface of the guide rod. Then, the connecting rod drives the rotating rod to move, so that the height of the roller is adjusted. Then, the object to be bent is placed on the roller. When the roller is under pressure, the support block as a whole is under downward pressure, so that the support rod pushes the slider to slide down along the surface of the guide rod, thereby stabilizing the spring under force. However, the rebound force of the stabilizing spring can push the slider to reset, so that the support rod pushes the support block to restore horizontal balance, and then pushes the object to be bent, so that the object slides fixedly along the surface of the roller.
[0016] 2. In this utility model, by setting up an auxiliary device, it is easier to place the object being bent stably. This avoids the situation where, during the bending process of thin plates, if the size of the object is too large, the operator needs to hold the thin plate with both hands to cooperate with the bending machine. Prolonged operation can easily lead to muscle strain in the arms and waist, increasing physical burden. When manually holding the thin plate, hand tremors or uneven force can affect the positioning accuracy of the thin plate, resulting in deviation of the bending angle. At the same time, because a lot of effort is required to maintain the stability of the thin plate, it is difficult to cooperate efficiently with the bending machine operation, reducing overall production efficiency. Therefore, this invention effectively improves the stability and practicality of the equipment. Attached Figure Description

[0024] Please see Figures 1-5 This utility model provides a technical solution: a bending machine, including a main body 1, a bending module 2, a lower die base 3, and an auxiliary device 4. The bending module 2 is disposed on the surface of the main body 1, and the lower die base 3 is fixedly connected to the surface of the main body 1. The main body 1 is provided with a mounting block 41 and a groove 44. The mounting block 41 is fixedly disposed on the surface of the main body 1, and the groove 44 is opened on the surface of the main body 1. A rotating shaft 42 is rotatably connected to the inner wall of the mounting block 41, and the auxiliary device 4 is disposed on the surface of the rotating shaft 42.
[0025] The specific setup and function of auxiliary device 4 will be explained below.
[0026] In this embodiment: the auxiliary device 4 includes a support block 43 and a roller 415. The support block 43 is rotatably connected to the surface of the rotating shaft 42, and the roller 415 is located on the inner wall of the support block 43.
[0027] Specifically, a slide rod 45 is fixedly connected to the inner wall of the groove 44, a stabilizing spring 46 is fixedly connected to the inner wall of the groove 44, and a slider 47 is fixedly connected to the end of the stabilizing spring 46 away from the groove 44.
[0028] Specifically, the surfaces of slider 47 and slider 45 are slidably connected, and a hinge seat 48 is fixedly connected to the surface of slider 47. A support rod 49 is rotatably connected to the inner wall of hinge seat 48. There are two sets of support rods 49 arranged symmetrically.
[0029] Specifically, the surface of the support block 43 is rotatably connected to a second rotating shaft 410. There are two sets of rotating shafts 410 arranged symmetrically. The end of the support rod 49 away from the hinge seat 48 is rotatably connected to the surface of the second rotating shaft 410.
[0030] Specifically, the surface of the support block 43 is fixedly connected with a fixing block 411, and the number of fixing blocks 411 is six.
[0031] Specifically, the surface of the fixing block 411 is fixedly connected with guide rods 412, and there are four sets of guide rods 412. The surface of the support block 43 is provided with guide grooves 413.
[0032] Specifically, a rotating rod 414 is slidably connected to the inner wall of the guide groove 413, and rollers 415 are rotatably connected to the surface of the rotating rod 414. There are three sets of rollers 415, and a connecting rod 416 is fixedly connected to the surface of the rotating rod 414.
[0033] Specifically, a screw 417 is rotatably connected to the surface of the fixing block 411, and the screw 417 is threaded to the inner wall of the connecting rod 416. A handle 418 is fixedly connected to the surface of the screw 417.
[0034] The aforementioned components achieve the following effects: The support block 43 facilitates the placement of the roller 415; the slide bar 45 allows the slider 47 to slide stably along its surface; the stabilizing spring 46 allows the slider 47 to move downwards when the roller 415 is subjected to pressure from a bent object, and the spring force of the stabilizing spring 46 then pushes the slider 47 upwards to reset; and the hinge seat 48 allows the support block 43 to push the support rod 49 under pressure, enabling the support rod 49 to rotate stably along the axis of the hinge seat 48. The support rod 49 facilitates the support block 43 and prevents the support block 43 from rotating along the axis of the pivot 42 after being subjected to pressure. The connection between the guide rod 412 and the connecting rod 416 facilitates the connection rod 416 to drive the roller 415 to slide stably along the surface of the guide rod 412. The roller 415 facilitates the transmission and support of the object to be bent. The transmission between the screw 417 and the connecting rod 416 facilitates the height adjustment of the roller 415 and prevents the object to be bent from having different thicknesses, which would cause it to not fit effectively on the lower mold base 3.
[0035] Working principle: By setting up auxiliary device 4, the lower mold base 3 is more convenient to use when placing the object to be bent stably. Rotating the handles 418 on both sides of the support block 43 causes the handles 418 to drive the connecting rod 416 to adjust its height, so that the connecting rod 416 slides vertically and stably along the surface of the guide rod 412. Then the connecting rod 416 drives the rotating rod 414 to move, so that the height of the roller 415 is adjusted. Then the object to be bent is placed above the roller 415. When the roller 415 is under pressure, the support block 43 is subjected to downward pressure, so the support rod 49 pushes the slider 47 to slide downward along the surface of the sliding rod 45, thereby compressing the stabilizing spring 46. However, the rebound force of the stabilizing spring 46 can push the slider 47 to reset, so that the support rod 49 pushes the support block 43 to restore horizontal balance, and then pushes the object to be bent, so that the object slides fixedly along the surface of the roller 415.
[0036] By setting up auxiliary device 4, it is easier to place the object being bent stably. This avoids the situation where, during the bending process of thin plates, if the size of the object is too large, the operator needs to hold the thin plate with both hands to cooperate with the bending machine. Prolonged operation can easily lead to muscle strain in the arms and waist, increasing physical burden. When manually holding the thin plate, hand tremors or uneven force can affect the positioning accuracy of the thin plate, resulting in deviation of the bending angle. At the same time, because a lot of energy is required to maintain the stability of the thin plate, it is difficult to cooperate efficiently with the bending machine operation, reducing the overall production efficiency. Therefore, this device effectively improves the stability and practicality of the equipment.
