[0001] This utility model relates to a sheet metal bending device, and more particularly to an automatic bending device. Background Technology
[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.
[0003] When bending sheet metal, the current method generally involves manually aligning each edge of the sheet metal with a mold before bending, which is inefficient and makes it difficult to ensure the consistency of bending results for each sheet metal in the same batch. While some automated bending machines exist, they still fail to provide adequate fixation of the sheet metal before bending, and the bending strength is often insufficient, resulting in unsatisfactory bending results.
[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0005] The purpose of this invention is to provide an automatic bending device that can bend the sheet metal in two steps after fixing it with a support plate and a fixed push plate, resulting in better bending consistency.
[0006] To achieve the above objectives, this utility model discloses an automatic bending device for bending sheet metal; the automatic bending device includes:
[0007] A base, on which a support plate is provided, the top surface of which is used to place the sheet material;
[0008] A fixing mechanism, comprising a fixing cylinder and a fixing push plate, wherein the fixing push plate is disposed at the output end of the fixing cylinder and is used to reciprocate in a direction perpendicular to the plate under the drive of the fixing cylinder, so that the plate can be clamped by the support plate and the fixing push plate together;
[0009] A bending mechanism includes a bending bracket, a bending slider, a bracket cylinder, a slider cylinder, and a bending cutter. The bending slider is slidably connected to the bending bracket and is located at the output end of the bracket cylinder. The slider cylinder is fixed to the end of the bending slider, and the bending cutter is located at the output end of the slider cylinder. The bending slider is used to reciprocate in a direction perpendicular to the sheet metal under the drive of the bracket cylinder, so that the edge of the sheet metal can be initially bent along the side jointly held by the support plate and the fixed push plate. The bending cutter is used to reciprocate in a direction parallel to the sheet metal under the drive of the slider cylinder, so that the edge of the sheet metal can be further bent along the side jointly held by the support plate and the fixed push plate.
[0010] As a further description of the above technical solution, the head of the bending blade facing the plate is configured as a wedge shape.
[0011] As a further description of the above technical solution, the bottom surface of the wedge is parallel to the plate, and the top surface of the wedge is not parallel to the plate.
[0012] As a further description of the above technical solution, the number of combinations of the bending mechanism and the support plate is set to multiple, and each combination of the bending mechanism and the support plate corresponds to one of the edges of the plate.
[0013] As a further description of the above technical solution, there are multiple fixed push plates, and each fixed push plate corresponds to one of the edges of the plate.
[0014] As a further description of the above technical solution, the support plate is configured as a trapezoidal body that retracts from the edge of the plate towards the center of the plate, so that when the plate is deeply bent by the bending knife, the support plate avoids the bending knife that moves back along a direction parallel to the plate.
[0015] As a further description of the above technical solution, the support plate, the fixed push plate, and the bending blade are arranged in parallel to each other.
[0016] As a further description of the above technical solution, the length dimensions of the support plate, the fixed push plate, and the bending blade are matched.
[0017] Based on the above technical solution, the beneficial effects of this utility model are as follows:
[0018] The automatic bending device of this utility model can fix the sheet metal with a support plate and a fixed push plate, and then bend the sheet metal in two steps. With the help of the downward pressure of the fixed push plate, the sheet metal is stably clamped between the support plate and the fixed push plate before bending. Then, the bending mechanism performs multi-stage bending on the sheet metal. First, the bending blade performs an initial bending in the vertical direction, and then a deeper bending parallel to the sheet metal is performed. The multiple bending makes the consistency of bending of the same batch of sheet metal better.

[0026] Please see Figure 1 This embodiment provides an automatic bending device for bending the sheet metal 100; the automatic bending device includes:
[0027] Base 1, a support plate 11 is provided on base 1, and the top surface of support plate 11 is used to place plate 100.
[0028] The fixing mechanism 2 includes a fixing cylinder 21 and a fixing push plate 22. The fixing push plate 22 is disposed at the output end of the fixing cylinder 21. The fixing push plate 22 is used to reciprocate in a direction perpendicular to the plate 100 under the drive of the fixing cylinder 21, so that the plate 100 can be clamped by the support plate 11 and the fixing push plate 22.
[0029] The bending mechanism 3 includes a bending bracket 31, a bending slider 32, a bracket cylinder 33, a slider cylinder 34, and a bending cutter 35. The bending slider 32 is slidably connected to the bending bracket 31 and is located at the output end of the bracket cylinder 33. The slider cylinder 34 is fixed at the end of the bending slider 32, and the bending cutter 35 is located at the output end of the slider cylinder 34. The bending slider 32 is used to reciprocate in a direction perpendicular to the plate 100 under the drive of the bracket cylinder 33, so that the edge of the plate 100 can be initially bent along the side jointly held by the support plate 11 and the fixed push plate 22. The bending cutter 35 is used to reciprocate in a direction parallel to the plate 100 under the drive of the slider cylinder 34, so that the edge of the plate 100 can be further bent along the side jointly held by the support plate 11 and the fixed push plate 22.
[0030] With the above structure, during use, the operator only needs to put the support cylinder 33 and the fixing cylinder 21 in the reset state so that the top of the support plate 11 is not obstructed and the plate 100 to be bent is placed on the top position of the support plate 11 and aligned with the edge of the support plate 11. Then, the fixing cylinder 21 is activated, causing the fixing cylinder 21 to drive the fixing push plate 22 to press down until the fixing push plate 22 contacts the top surface of the plate 100. Finally, the fixing push plate 22 and the support plate 11 together tightly clamp the plate 100 near the edge. At this time, the fixing push plate 22 is located at... Figure 1 The position is indicated by the dotted line. Then, the bending bracket 31 in the bending mechanism 3 is activated. The bending bracket 31 drives the bending slider 32 to move downwards towards the plate 100, causing the slider cylinder 34 on the bending slider 32, especially the bending blade 35 at the end of the slider cylinder 34, to press down, pressing down the edge of the plate 100. A localized area of the edge of the plate 100 undergoes bending and rotation relative to the clamping point of the fixed push plate 22 and support plate 11, achieving the initial bend. Then, the slider cylinder 34 drives the bending blade 35 to advance towards the center of the plate 100, causing a deeper bend in the localized area of the edge of the plate 100 under the horizontal push of the bending blade 35. The bend of the plate 100 is deepened until the preset deformation angle is fully achieved.
[0031] It is worth noting that, in this embodiment, with the help of the flexible drive of the bending blade 35 by the slider cylinder 34, the bending blade 35 can perform multiple deep bends on the sheet metal 100 until the degree of bending of the sheet metal 100 fully meets the requirements.
[0032] In the above-described process, the sheet material 100 can be fixed by the support plate 11 and the fixed push plate 22, and then the sheet material can be bent in two steps. Compared with the existing manual bending or mechanical bending that only requires one bending, this embodiment uses graded multiple bending to make the bending degree of the sheet material 100 in the same batch more consistent. At the same time, with the downward pressure of the fixed push plate 22, the sheet material 100 is stably clamped between the support plate 11 and the fixed push plate 22 before bending, so that the sheet material 100 is more stably fixed during the bending process and avoids deviation.
[0033] Furthermore, the head of the bending blade 35 facing the sheet metal 100 is wedge-shaped. Simultaneously, the bottom surface of the wedge is parallel to the sheet metal 100, while the top surface is not parallel to the sheet metal 100. Specifically, the wedge-shaped head design of the bending blade 35 allows for a smaller contact angle and less friction between the bending blade 35 and the sheet metal 100 during the deep bending process, thus preventing damage to the sheet metal 100 from the sharp bending blade 35.
[0034] Furthermore, the number of combinations of bending mechanism 3 and support plate 11 is set to multiple, with each combination of bending mechanism 3 and support plate 11 corresponding to one side of plate 100. Simultaneously, the number of fixed push plates 22 is also multiple, with each fixed push plate 22 corresponding to one side of plate 100. Specifically, in this embodiment, the plate 100 to be bent is set as a regular rectangle. The automatic bending mechanism in this embodiment can simultaneously bend all three sides of the rectangle. Each side corresponds to a set of fixed push plates 22, bending mechanism 3, and support plate 11. The three sets of fixed push plates 22, bending mechanism 3, and support plate 11 are arranged vertically at 90 degrees on the top surface of the base 1, achieving high bending efficiency.
[0035] Furthermore, the support plate 11 is configured as a trapezoidal body that retracts from the edge of the sheet 100 towards the center of the sheet 100, so that when the sheet 100 is deeply bent by the bending blade 35, the support plate 11 avoids the bending blade 35, which moves back to its original position in a direction parallel to the sheet 100. Specifically, during the horizontal cutting process of the bending blade 35, the special avoidance of the trapezoidal body prevents the support plate 11 from being impacted by the bending blade 35, thus avoiding tool wear and affecting the product's lifespan.
[0036] Of course, in some other embodiments, the avoidance structure of the support plate 11 can also be set as a stepped shape, as long as it can avoid the bending knife 35 from cutting in the horizontal direction and does not affect the bending angle of the plate 100.
[0037] Furthermore, the support plate 11, the fixed push plate 22, and the bending blade 35 are arranged parallel to each other. Simultaneously, the lengths of the support plate 11, the fixed push plate 22, and the bending blade 35 are matched. Specifically, in this embodiment, the lengths of the support plate 11, the fixed push plate 22, and the bending blade 35 match the length of one side of the corresponding sheet material 100 to be bent, making the structure more compact while fulfilling the bending function.
