Description

Technical Field

[0001] This utility model relates to the field of metal support technology, specifically a metal support with a residual stress release guiding structure. Background Technology

[0002] As is well known, residual stress is easily generated during the design and manufacturing of metal supports, especially when welding, stamping, or other forms of metal processing are involved. If these residual stresses are not managed and released, they may cause a series of problems in the structural components during their service life. Welding is a common method of metal connection, but during the welding process, due to the rapid increase and subsequent cooling of local temperature, uneven contraction and expansion will occur inside the material, thus forming residual stress. For example, stamping and bending processes introduce residual stress by causing plastic deformation of metal through external force. In these manufacturing processes, if the cooling rate is inconsistent or impurities are present, internal stress may also be generated. When the residual stress exceeds the yield strength of the material, it will cause permanent shape changes in the workpiece, affecting its function and aesthetics. Especially in high stress concentration areas such as welded joints, excessive residual stress may lead to the formation of microcracks, which will expand with the increase of service time and eventually lead to the complete fracture of the structural components. Even if it does not cause immediate failure, residual stress will significantly shorten the fatigue life of the material and increase the risk of accidental failure. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a metal bracket with a residual stress relief guiding structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal bracket with a residual stress release guiding structure, comprising mounting plates, two mounting plates symmetrically arranged, a support mechanism between the two mounting plates, the support mechanism comprising a release groove and a support column, the release groove being formed inside the mounting plate, a positioning groove being formed between the release groove and one end of the mounting plate, the two ends of the support column abutting against the positioning grooves of the two mounting plates, a fastening groove being formed inside the support column, a fixing groove being formed on both sides of the fastening groove, an inclined plate being provided on the fixing groove, a lead screw and an adjusting plate being provided on the fastening groove, a threaded hole being formed on the adjusting plate, the lead screw passing through the threaded hole, a bearing seat being provided between the lead screw and the fastening groove, the lead screw extending to one side of the support column, inclined blocks being provided on both sides of the adjusting plate, a buffer sleeve being provided on the release groove, and release ports being provided at both ends of the support column.

[0005] Furthermore, the present invention is improved in that the support column is provided with a release mechanism, the release mechanism includes release points installed around the support column, the release mechanism is located at one end of the support column, and two release mechanisms are provided and symmetrically arranged.

[0006] Furthermore, the present invention is improved in that the release port has a conical groove structure.

[0007] Furthermore, the present invention is improved in that the release port is provided with multiple ports.

[0008] Furthermore, the present invention is improved in that the support mechanism is provided in two symmetrical arrangements.

[0009] Furthermore, the present invention is improved by providing a mesh reinforcing plate inside the mounting plate.

[0010] Furthermore, an improvement of this utility model is that the mesh reinforcing plate is made of aluminum alloy.

[0011] Compared with the prior art, this utility model provides a metal bracket with a residual stress relief guiding structure, which has the following beneficial effects: This metal bracket with a residual stress relief guiding structure provides an effective stress relief path by setting a relief groove inside the mounting plate and configuring a buffer sleeve on it. This prevents excessive local stress from causing material damage or deformation. When the structure is subjected to external loads, the stress can be evenly distributed throughout the structure through the relief groove, avoiding stress concentration that may occur in traditional designs. When the screw is rotated, the adjusting plate moves linearly along the fastening groove, causing the inclined block to contact and push the inclined plate, so that the inclined plate extends out of the fixing groove and abuts against the buffer sleeve in the relief groove. This ensures that the support column is firmly fixed between the two mounting plates, simplifying the installation process. The relief ports at both ends of the support column effectively guide and release residual stress. Attached Figure Description

[0014] 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.

[0015] Please see Figures 1-4 This utility model relates to a metal bracket with a residual stress release guiding structure, comprising a mounting plate 1, wherein two mounting plates 1 are provided and symmetrically arranged, and a support mechanism is provided between the two mounting plates 1. The support mechanism includes a release groove and a support column 2. The release groove is formed inside the mounting plate 1, and a positioning groove is formed between the release groove and one end of the mounting plate 1. The two ends of the support column 2 abut against the positioning grooves of the two mounting plates 1. A fastening groove is formed inside the support column, and a fixing groove is formed on both sides of the fastening groove. An inclined plate 3 is provided on the fixing groove, and a lead screw 4 and an adjusting plate 5 are provided on the fastening groove. A threaded hole is formed on the adjusting plate 5, through which the lead screw 4 passes. A bearing seat 6 is provided between the lead screw 4 and the fastening groove, and the lead screw 4 extends to one side of the support column 2. An inclined block 7 is provided on both sides of the adjusting plate 5. A buffer sleeve 8 is provided on the release groove, and a release port 9 is provided at both ends of the support column 2. In this embodiment, the support... The column 2 is inserted into the positioning grooves of the two mounting plates 1 and abuts against the corresponding release grooves. Then, the lead screw 4 is rotated. The lead screw 4 rotates at a stable angle through the bearing seat 6. Through the threaded hole of the adjusting plate 5, the adjusting plate 5 can move linearly in the fastening groove. The adjusting plate 5 drives the inclined block 7 to move, so that the inclined block 7 contacts and pushes the inclined plate 3. The inclined plate 3 moves linearly in the fixing groove. The inclined plate 3 extends out of the fixing groove and abuts against the release groove. At this time, the inclined plate 3 and the support column 2 are wrapped and fixed by the buffer sleeve 8 of the release groove, thereby achieving a firm assembly of the support column 2 on the two mounting plates 1. The release groove is located inside the mounting plate 1 to provide a stress release path and prevent excessive local stress from causing material damage or deformation. At the same time, the buffer sleeve 8 buffers and disperses the pressure, which can greatly reduce the problem of excessive local pressure on the support column 2. Moreover, the release ports 9 at both ends of the support column 2 guide and release residual stress, solving the problem of stress accumulation at the weld joint in the traditional welded support structure, which leads to breakage.

[0016] To further prevent fractures caused by stress accumulation, the support column 2 is equipped with a release mechanism in this design. The release mechanism includes release points 10, which are installed around the support column 2. The release mechanism is located near one end of the support column 2. There are two release mechanisms arranged symmetrically. By evenly distributing the release points 10, stress is dispersed to prevent excessive local stress.

[0017] In order to further optimize the stress release effect and reduce the problem of excessive local pressure on the support column 2, in this solution, the release port 9 is a conical groove structure, which helps to guide the stress to be dispersed along a specific path, and also plays a certain buffering role.

[0018] To enhance stress relief capabilities and improve the overall structural safety, this design includes multiple release ports 9, ensuring that even if one release port 9 fails, the remaining release ports 9 can still function effectively and maintain the integrity of the structure.

[0019] To enhance the overall stability and load-bearing capacity of the structure, this design includes two symmetrically arranged support mechanisms. This symmetrical layout not only balances the load distribution but also increases system redundancy and improves reliability.

[0020] In order to improve the strength and durability of the mounting plate 1 and effectively disperse the stress applied to it, in this solution, the mounting plate 1 is provided with a mesh reinforcing plate 11 inside, which greatly improves the rigidity and bending resistance of the mounting plate 1.

[0021] The aforementioned mesh reinforcing plate 11 can be made of any material. In order to further improve the structural strength, in this solution, the mesh reinforcing plate 11 is made of aluminum alloy, which is lightweight and has high strength.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
