Description

Technical Field

[0001] This utility model relates to the technical field of cold rolling of metal materials, and in particular to a precision cold-rolled stainless steel strip with high surface quality. Background Technology

[0002] Precision cold-rolled stainless steel strip is a thin, narrow strip processed using a special technique. Its stainless steel base ensures excellent corrosion resistance, a certain level of strength, and aesthetic appeal. "Cold rolling" refers to the re-rolling of a thicker steel coil after hot rolling at room temperature. This process improves strength, surface finish, and dimensional accuracy. "Precision" signifies strict control over thickness tolerances, shape, and surface quality. This type of strip is commonly used in high-end fields such as electronics, medical devices, the automotive industry, and aerospace. High-surface-quality strips, while retaining the aforementioned performance advantages, achieve an even higher level of visual appeal, tactile feel, and specific physical and chemical properties.

[0003] However, in current production processes, precision cold-rolled stainless steel strip coils are often cut into precision cold-rolled stainless steel strip sheets. However, when these sheets are stacked, dust or fine impurities between layers can easily cause surface scratches. Furthermore, during inter-process handling, the edges and corners are easily damaged by impacts. These surface scratches and edge damage can directly lead to product scrap or downgrading to substandard products, resulting in losses.

[0004] Therefore, this application provides a precision cold-rolled stainless steel strip with high surface quality to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-surface-quality precision cold-rolled stainless steel strip. This device can prevent scratches during stacking and also prevent damage from bumps during handling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-surface-quality precision cold-rolled stainless steel strip includes four triangular sheaths, two longitudinal sheaths, two transverse sheaths, and a precision cold-rolled stainless steel strip plate. The four triangular sheaths have triangular grooves on their front and rear ends and on both sides of their outer walls. The two longitudinal sheaths have first grooves on both sides of their outer walls. The two transverse sheaths have second grooves on their front and rear ends. A barrier pad is movably disposed on the upper surface of the precision cold-rolled stainless steel strip plate, and multiple protrusions are fixedly disposed on the upper surface of the barrier pad.

[0007] Furthermore, the four corners of the precision cold-rolled stainless steel strip plate are slidably disposed inside the four triangular grooves.

[0008] Furthermore, the front and rear ends of the precision cold-rolled stainless steel strip plate are respectively slidably disposed inside the two second grooves.

[0009] Furthermore, the two ends of the outer wall of the precision cold-rolled stainless steel strip plate are respectively slidably disposed inside the two first grooves.

[0010] Furthermore, the four triangular sheaths, two longitudinal sheaths, two transverse sheaths, barrier pads, and multiple protrusions are all made of medium-hardness silicone rubber.

[0011] This utility model has the following beneficial effects: 1. This utility model proposes a high-surface-quality precision cold-rolled stainless steel strip. After the precision cold-rolled stainless steel strip coil is cut into precision cold-rolled stainless steel strip plates according to requirements, the four corners are first embedded into the triangular grooves of four triangular protective sleeves. Then, the sides and front and rear ends of the precision cold-rolled stainless steel strip plate are respectively inserted into the first grooves of two longitudinal protective sleeves and the second grooves of two transverse protective sleeves. Through the above steps, the outer edge of the plate can be fully covered and protected, effectively avoiding damage caused by collisions with equipment or walls during transportation.

[0012] 2. This utility model proposes a high-surface-quality precision cold-rolled stainless steel strip. Barrier pads are placed on top of the precision cold-rolled stainless steel strip flat sheet, ensuring they are located in the central area enclosed by two longitudinal sleeves and two transverse sleeves. Subsequent barrier pads are placed in the same manner, allowing the precision cold-rolled stainless steel strip flat sheets to be stacked layer by layer, achieving stable multi-layer stacking. In this structure, the barrier pads effectively prevent dust and fine impurities from scratching the flat sheet surface; simultaneously, the multiple protrusions on their surface increase interlayer friction, preventing relative sliding of the flat sheets during stacking, thereby ensuring overall stability during handling and storage.

[0015] 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.

[0016] Reference Figure 1 — Figure 4 An embodiment of this utility model provides a high-surface-quality precision cold-rolled stainless steel strip, comprising four triangular sheaths 1, two longitudinal sheaths 2, two transverse sheaths 3, and a precision cold-rolled stainless steel strip plate 6. The four triangular sheaths 1 have triangular grooves 7 at their front and rear ends and on both sides of their outer walls. The two longitudinal sheaths 2 have first grooves 8 on both sides of their outer walls. The two transverse sheaths 3 have second grooves 9 at their front and rear ends. A barrier pad 4 is movably disposed on the upper surface of the precision cold-rolled stainless steel strip plate 6, and multiple protrusions 5 are fixedly disposed on the upper surface of the barrier pad 4.

[0017] Specifically, after the precision cold-rolled stainless steel strip coil is cut into precision cold-rolled stainless steel strip plates 6, the protective assembly process needs to be completed sequentially: First, four triangular sleeves 1 are respectively fitted onto the four corners of the precision cold-rolled stainless steel strip plate 6, ensuring that the corners are fully embedded in the corresponding triangular grooves 7; then, two longitudinal sleeves 2 are respectively installed on the two side edges of the precision cold-rolled stainless steel strip plate 6, so that the front and rear ends of the precision cold-rolled stainless steel strip plate 6 are accurately inserted into the two first grooves 8; next, two transverse sleeves 3 are respectively fitted onto the front and rear ends of the precision cold-rolled stainless steel strip plate 6, and their side edges are embedded into the two second grooves 9; finally, the barrier pad 4 is placed flat on the surface of the precision cold-rolled stainless steel strip plate 6 and positioned in the central area enclosed by the longitudinal sleeves 2 and transverse sleeves 3. After all the precision cold-rolled stainless steel strip plates 6 have been installed in the above manner, they can be neatly stacked from bottom to top. During the stacking of multiple precision cold-rolled stainless steel strip plates 6, the barrier pad 4 effectively isolates interlayer contact, preventing dust or impurities from slipping and causing surface scratches. Simultaneously, the multiple protrusions 5 on its surface increase frictional resistance, preventing relative sliding between the precision cold-rolled stainless steel strip plates 6. During subsequent handling or movement, the four triangular sleeves 1, two longitudinal sleeves 2, and two transverse sleeves 3 assembled around the precision cold-rolled stainless steel strip plates 6 together form an overall protective structure, effectively buffering external impacts and preventing damage to the edges and surfaces of the precision cold-rolled stainless steel strip plates 6 due to collisions. It should be noted that medium-hardness silicone rubber is a solid silicone material with a Shore A hardness typically between 40°A and 70°A. The device uses 70°A medium-hardness silicone rubber, a material that is moderately soft and hard, possessing both sufficient support and good elasticity. Standard parts used in this application can be directly purchased from the market, while irregularly shaped parts can be customized according to the specifications and drawings. The specific connection methods for each part all employ existing mature technologies such as bolt connections, riveting connections, welding, and other conventional methods. Mechanical components and equipment all use conventional models from the prior art, and therefore will not be described in detail. Any content not described in detail in this specification belongs to existing technology known to those skilled in the art.

[0018] Reference Figure 3 , Figure 4 The four corners of the precision cold-rolled stainless steel strip plate 6 are respectively slidably set inside the four triangular grooves 7, the front and rear ends of the precision cold-rolled stainless steel strip plate 6 are respectively slidably set inside the two second grooves 9, and the two ends of the outer wall of the precision cold-rolled stainless steel strip plate 6 are respectively slidably set inside the two first grooves 8.

[0019] Specifically, inserting the four corners of the precision cold-rolled stainless steel strip plate 6 into the four triangular grooves 7 effectively prevents damage to the corners from contact or collision with other equipment or door frames during transfer. Simultaneously, embedding the front and rear ends and the outer sides of the precision cold-rolled stainless steel strip plate 6 into the first groove 8 and second groove 9 within the two longitudinal protective sleeves 2 and two transverse protective sleeves 3 further protects the front and rear ends and the outer side walls, preventing damage from accidental bumps during handling or operation. Through this structural design, the overall packaging protection is more comprehensive and reliable, helping to maintain the surface quality and dimensional accuracy of the precision cold-rolled stainless steel strip plate 6.

[0020] Reference Figure 3 , Figure 4 The four triangular sheaths 1 have triangular grooves 7 at the front and rear ends and on both sides of the outer wall. The two longitudinal sheaths 2 have first grooves 8 on both sides of the outer wall. The two transverse sheaths 3 have second grooves 9 at the front and rear ends. The upper end of the precision cold-rolled stainless steel strip plate 6 is movably provided with a barrier pad 4. The upper end of the barrier pad 4 is fixedly provided with multiple protrusions 5. The four triangular sheaths 1, two longitudinal sheaths 2, two transverse sheaths 3, barrier pad 4 and multiple protrusions 5 are all made of medium-hardness silicone rubber.

[0021] Specifically, through the design of the triangular groove 7, the triangular sheath 1 can fit more tightly at the corner of the precision cold-rolled stainless steel strip plate 6; at the same time, the first groove 8 and the second groove 9 respectively ensure that the longitudinal sheath 2 and the transverse sheath 3 tightly cover the outer walls and front and rear ends of the precision cold-rolled stainless steel strip plate 6. This multi-layered fitting structure effectively enhances the overall stability of the sheath and can prevent the triangular sheath 1, longitudinal sheath 2, and transverse sheath 3 from falling off during transportation or use. In addition, the sheath is made of medium-hardness silicone rubber, which can provide sufficient cushioning protection for the precision cold-rolled stainless steel strip plate 6 while avoiding scratches on its surface due to high contact hardness, thus balancing protective effect and safety of use.

[0022] Working principle: After cutting and processing precision cold-rolled stainless steel strip into precision cold-rolled stainless steel strip plates 6 according to requirements, the four corners of the precision cold-rolled stainless steel strip plate 6 are respectively embedded into the triangular grooves 7 of the four triangular protective sleeves 1; then, its two sides and front and rear ends are respectively inserted into the first grooves 8 of the two longitudinal protective sleeves 2 and the second grooves 9 of the two transverse protective sleeves 3, so that the protective sleeves completely cover the outer edge of the precision cold-rolled stainless steel strip plate 6; finally, a barrier pad 4 is placed on the upper surface of the precision cold-rolled stainless steel strip plate 6, in the central area formed by the longitudinal protective sleeves 2 and the transverse protective sleeves 3. This enables the stable stacking and safe handling of multiple layers of precision cold-rolled stainless steel strip plates 6.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
