Description

Technical Field

[0001] This utility model relates to the field of product component structure, and in particular to a stress relief structure. Background Technology

[0002] In the processing of metal-plastic structural components, the traditional one-time direct processing technology is currently widely used to form the structure. However, with the increasing complexity and diversity of product designs, many product structures are not entirely made of metal, but instead incorporate plastic components for insulation. This combination of metal and plastic presents significant challenges to processing.

[0003] The existing molding structure uses a one-time processing method, resulting in extremely poor dimensional stability of the internal cavity. In the original structure, the metal components are not disconnected, and during the processing of the internal cavity, the stress release of the metal and plastic differs significantly due to their material properties. Metal has higher rigidity, leading to significant stress concentration, while plastic is relatively soft, resulting in a more dispersed stress distribution. When processing the internal cavity of the overall structure, the asynchronous and uneven stress release between the metal and plastic causes significant fluctuations in the post-processed dimensions, making it difficult to meet the high-precision dimensional requirements of the product. Utility Model Content

[0004] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0005] A stress relief structure includes: a metal substrate and a plastic substrate that is fitted thereto; wherein the plastic substrate is installed in the inner ring of the metal substrate; and the metal substrate has at least one notch for releasing internal stress of the metal substrate.

[0006] Preferably, the metal substrate includes two mating blocks, which are disposed at the notch and are configured to be close to or far apart simultaneously.

[0007] Preferably, the metal substrate further includes two grooves formed on the metal substrate, and the mating block is installed in the groove.

[0008] Preferably, the metal substrate further includes: two lead screws, one end of which is threadedly connected to the mating block, and the other end of which penetrates the inner wall of the groove; and an adjustment knob installed at the end of the lead screw away from the mating block.

[0009] Preferably, the metal substrate further includes reinforcing ribs mounted thereon, the reinforcing ribs being used to enhance the structural strength of the metal substrate.

[0010] Preferably, the reinforcing rib is provided with a pre-set stress relief groove, which is used to adjust the stress distribution at the reinforcing rib.

[0011] Preferably, the metal substrate has multiple notches, and the multiple notches are evenly distributed along the circumference of the metal substrate, with the included angle between two adjacent notches being equal.

[0012] Preferably, a buffer layer is provided between the inner ring of the plastic substrate and the metal substrate.

[0013] This invention provides a stress relief structure. Compared with existing technologies, it offers the following advantages: By setting a notch in the metal substrate, the metal connection is disconnected in advance, allowing for the early and more controllable release of metal stress. This avoids excessive deformation caused by sudden stress release and redistribution during subsequent internal cavity processing, improving the stability of internal cavity machining dimensions and meeting the high-precision dimensional requirements of products. By rotating the adjustment knob to move the mating block closer or further away, the notch in the metal substrate can be opened or closed, flexibly adjusting the stress distribution and release degree. This stress relief structure can better adapt to the processing requirements of different products, improving processing adaptability and flexibility, and expanding the application range of this stress relief structure.

[0023] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0025] Reference Figures 1-5 A stress relief structure includes: a metal substrate 100 and a plastic substrate 200 that is fitted thereto; wherein the plastic substrate 200 is installed in the inner ring of the metal substrate 100; the metal substrate 100 is provided with at least one notch 101 for releasing the internal stress of the metal substrate 100.

[0026] In this embodiment, the metal substrate 100 is the main load-bearing part of the entire structure. Its material can be selected according to the actual application requirements, such as aluminum alloy or stainless steel. The notches 101 on the metal substrate 100 are evenly distributed along its circumference, with equal angles between adjacent notches 101. The specific angles can be adjusted according to the size of the metal substrate 100 and stress release requirements. These notches 101 prematurely disconnect the metal connection, effectively breaking the original stress balance, allowing the internal stress of the metal substrate 100 to be released in a more controllable manner. This prevents excessive deformation of the metal material due to the sudden release and redistribution of internal stress during subsequent internal cavity processing, thus ensuring the stability of the processed dimensions.

[0027] The metal substrate 100 includes: two mating blocks 102, which are disposed at the notch 101 and are configured to be simultaneously close to or far from each other; two grooves 103, which are formed on the metal substrate 100 and in which the mating blocks 102 are installed; two lead screws 104, one end of which is threadedly connected to the mating block 102 and the other end of which penetrates the inner wall of the groove 103; and an adjustment knob 105, which is installed at the end of the lead screw 104 away from the mating block 102.

[0028] The shape and size of the aforementioned mating block 102 are adapted to the notch 101 to ensure stable installation and movement at the notch 101. The two mating blocks 102 are designed to move closer or further apart simultaneously. This is achieved by installing the mating blocks 102 within the groove 103, allowing them to slide within the groove. Each mating block 102 is threadedly connected to a lead screw 104. Rotating the adjustment knob 105 rotates the lead screw 104. Due to the threaded connection between the lead screw 104 and the mating block 102, the rotation of the lead screw 104 is converted into linear movement of the mating block 102 within the groove 103, thus enabling the two mating blocks 102 to move closer or further apart simultaneously. When the two mating blocks 102 are mated together, the notch 101 on the metal substrate 100 is closed. When the two mating blocks 102 move further apart, the notch 101 on the metal substrate 100 is opened.

[0029] The metal substrate 100 also includes reinforcing ribs 300 mounted thereon, which are used to enhance the structural strength of the metal substrate 100. A pre-set stress relief groove 301 is provided on the reinforcing rib 300, which is used to adjust the stress distribution at the reinforcing rib 300.

[0030] The function of the aforementioned reinforcing rib 300 is to enhance the structural strength of the metal substrate 100 and improve its stability under external forces. The reinforcing rib 300 can be made of the same or similar material as the metal substrate 100 and is firmly connected to the metal substrate 100 through welding, integral molding, or other methods. A pre-set stress relief groove 301 is provided on the reinforcing rib 300. The shape of the pre-set stress relief groove 301 can be trapezoidal, U-shaped, etc. (the specific shape is determined according to the actual stress distribution and relief requirements) to ensure that the stress distribution at the reinforcing rib 300 can be effectively adjusted, further improving the stress relief effect of the entire metal substrate 100.

[0031] The metal substrate 100 has multiple notches 101, which are evenly distributed along the circumference of the metal substrate 100, with equal included angles between adjacent notches 101. The angles are designed according to the specific dimensions of the metal substrate 100 and the required stress relief, ranging from 30° to 90°. This evenly distributed notch 101 arrangement allows for more uniform and earlier stress relief in the metal substrate 100, preventing stress concentration in localized areas. This significantly improves the dimensional stability and consistency during subsequent internal cavity machining, ensuring that the product meets higher precision machining requirements.

[0032] A buffer layer is provided between the plastic substrate 200 and the inner ring of the metal substrate 100. The buffer layer is made of a highly elastic material, such as rubber or silicone. The thickness of the buffer layer can be adjusted according to actual conditions, generally between 0.5-2 mm, and its hardness ranges from Shore hardness 30-60. The presence of the buffer layer can effectively alleviate the impact on the plastic substrate 200 during the stress release process of the metal substrate 100, and prevent the plastic substrate 200 from deforming due to stress transmission, thereby ensuring the dimensional stability and performance reliability of the entire structural component.

[0033] During use, based on actual application requirements, a suitable metal material is selected to fabricate the metal substrate 100, and a suitable plastic material is selected to fabricate the plastic substrate 200. The number, size, shape, and included angle between adjacent notches 101 on the metal substrate 100 are determined. The plastic substrate 200 is installed within the inner ring of the metal substrate 100. A buffer layer is installed between the inner rings of the metal substrate 100 and the plastic substrate 200 to mitigate the impact of subsequent stress release on the plastic substrate 200. Two mating blocks 102 are respectively installed in corresponding grooves 103 on the metal substrate 100, allowing the mating blocks 102 to slide within the grooves 103. One end of the lead screw 104 is threaded onto the mating block 102. One end of the screw 104 penetrates the inner wall of the groove 103, and an adjustment knob 105 is installed at the end of the screw 104 away from the docking block 102. The reinforcing rib 300 is firmly connected to the metal substrate 100 by welding or integral molding, and it is ensured that the pre-set stress relief groove 301 on the reinforcing rib 300 has been opened according to the design requirements. Since multiple notches 101 are evenly distributed along the circumference on the metal substrate 100, the stress inside the metal substrate 100 will begin to be released in advance due to the presence of these notches 101 before the internal cavity of the structural component is processed, breaking the original stress balance and dispersing the stress in a more controllable way, so as to avoid excessive deformation of the metal material due to sudden stress release and redistribution during subsequent processing.

[0034] If further adjustment of the stress state of the metal substrate 100 is required, the adjustment knob 105 can be rotated. Rotating the adjustment knob 105 drives the lead screw 104 to rotate. Due to the threaded connection between the lead screw 104 and the mating block 102, the rotation of the lead screw 104 is converted into linear movement of the mating block 102 within the groove 103, allowing the two mating blocks 102 to simultaneously move closer or further apart. When the two mating blocks 102 are mated together, the notch 101 on the metal substrate 100 can be closed; when the two mating blocks 102 are moving away from each other, the notch 101 on the metal substrate 100 can be opened, further adjusting the stress distribution and release degree of the metal substrate 100.

[0035] During the stress release process, the pre-set stress release groove 301 on the reinforcing rib 300 plays a role in adjusting the stress distribution at the reinforcing rib 300. It works in conjunction with the notch 101 on the metal substrate 100 to further improve the stress release effect of the entire metal substrate 100 and prevent stress from concentrating in local areas.

[0036] After completing the stress release and adjustment steps described above, the internal cavity of the structural component is machined. At this point, because the stress in the metal substrate 100 has been released in advance and effectively controlled, the metal material will not deform excessively due to internal stress issues, ensuring the stability and consistency of the internal cavity machining dimensions and meeting high-precision machining requirements. Throughout the process, the buffer layer continuously plays a role, effectively absorbing and buffering the impact force generated during the stress release of the metal substrate 100, protecting the plastic substrate 200 from damage, ensuring the dimensional stability and performance reliability of the entire structural component, and guaranteeing its normal use.

[0037] In summary, compared with existing technologies, it has the following beneficial effects:

[0038] By setting a notch 101 on the metal substrate 100, the metal connection is disconnected in advance, allowing the metal stress to be released in advance and in a more controllable manner. This avoids excessive deformation caused by sudden stress release and redistribution during subsequent internal cavity machining, improves the stability of the internal cavity machining dimensions, and can meet the high-precision dimensional requirements of the product.

[0039] By rotating the adjustment knob 105 to move the mating block 102 closer to or further away, the notch 101 on the metal substrate 100 can be opened or closed, flexibly adjusting the stress distribution and release degree. The stress release structure of this solution can better adapt to the processing requirements of different products, improve the adaptability and flexibility of processing, and expand the application range of the stress release structure.
