[0001] The utility model relates to the technical field of sheets or plates, in particular to profiles with a tear structure. Background Art

[0002] In profile extrusion dies, the strength cannot meet the extrusion requirements, and it is easily affected by temperature and pressure during extrusion, prone to die deflection, fracture, etc., resulting in die scrapping. For example, the Chinese patent with the publication number CN208267662U discloses a tearable aluminum lattice strip for aluminum alloy doors, providing the following technical solution. A tearable aluminum lattice strip for aluminum alloy doors has a cross-sectional shape composed of three "mouth" shapes arranged side by side. At the middle position of the outer side of the two "mouth" shapes on both sides, there are tearable strips. There are four inner and outer concave openings at the connection part between the outer side of the two "mouth" shapes and the tearable strips. The concave openings facilitate the tearing of the tearable strips from the outer side of the two "mouth" shapes on both sides. At the corresponding positions of the inner sides of the two "mouth" shapes and the tearable strips, there are sawteeth respectively. Glass glue can be applied on the sawteeth to facilitate the connection of glass decorative flowers. The advantages of the utility model are: good concealment, firm installation, not easy to cause the glass decorative flowers to shake and the glass to be damaged.

[0003] However, for the above-mentioned tearable aluminum lattice strip for aluminum alloy doors, the extrusion molding is poor, the product extrusion success rate is low, and the stability of the cross-sectional opening size is poor. Summary of the Utility Model

[0004] The utility model solves the problems of low success rate, poor stability and easy die fracture in the prior art. The utility model proposes a steel shell tearable profile, achieving the purposes of good molding, stable opening size, high extrusion success rate and good stability.

[0005] To achieve the above purposes, the utility model adopts the following technical solutions:

[0006] A steel shell tearable profile includes a profile body. The cross-section of the profile body is in a semi-closed shape with an opening on one side. The opening is provided with a tearable tear structure, and opening protrusions are provided at the connection parts of both ends of the tear structure and the opening.

[0007] The advantage of such a design is that it provides a stable opening structure, which can be easily torn when needed. At the same time, the structural strength is enhanced through the opening protrusions, avoiding deformation and damage during the production process.

[0008] Preferably, a plurality of "C" - shaped protrusions are provided on the inner wall of the cross-section of the profile body, and the wall thickness at the "C" - shaped protrusions is greater than that of the remaining part.

[0009] The advantage of such a design is that it increases the strength and rigidity of the inner wall of the profile, reduces deformation during use, and at the same time provides better support and stability.

[0010] Preferably, the tear structure is in the shape of an elongated strip, with its two ends respectively connected to the two ends of the opening. A tear protrusion is provided at the connection between the two ends of the tear structure. The thickness of the opening protrusion is greater than the wall thickness of the rest of the profile body, and the size of the tear protrusion is smaller than the wall thickness of the profile body.

[0011] The advantage of this design is that, through different wall thickness designs, the stability and tearability of the tear structure are improved, while maintaining the overall strength and balance of the profile.

[0012] Preferably, one of the "C"-shaped protrusions is located on the side wall of the opening of the profile body, and the other is located on the top wall on the other side. The distance between the centers of the two is 34.88mm to 35.18mm, the outer diameter is 4.8mm to 5mm, and the inner diameter is 2.4mm to 2.6mm.

[0013] The advantage of this design is that the precise geometric dimensions ensure the structural stability of the profile, reduce possible errors in the production process, and improve product consistency and quality.

[0014] Preferably, the cross-section of the profile body is rectangular, the length of the profile body is 1103 mm to 1103.6 mm, the width is 49.4 mm to 49.8 mm, and the height is 49.7 mm to 45.1 mm.

[0015] Preferably, the four corners of the cross section of the profile body are rounded, with a radius of 4 mm to 4.2 mm.

[0016] The advantage of this design is that the rounded corners can reduce stress concentration, avoid cracks and breakage during use, and improve the durability and safety of the profile.

[0017] Preferably, the cross-section of the profile body is a long cantilever cross-section structure, and the ratio of the size of the opening to the height of the profile body is greater than 3.

[0018] The advantage of this design is that the long cantilever cross-section structure improves the bending resistance and rigidity of the profile, while at the same time, through reasonable size ratio design, it avoids deformation and cracking during the processing process.

[0019] Preferably, the diameter of the opening protrusion is 1.7 mm to 1.9 mm.

[0020] The advantage of this design is that the precise opening protrusion size provides better positioning and fixing effects, enhances the overall stability of the profile, and facilitates the tearing operation, thereby improving production efficiency and product quality.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The utility model provides a stable opening structure that combines a tearable notch with an opening protrusion. This not only allows for easy tearing when needed, but also significantly enhances structural strength through the opening protrusion, reducing the risk of deformation and breakage during production, making the overall product quality more reliable. Furthermore, the inner wall of the cross-section of the profile body is provided with "C"-shaped protrusions. The wall thickness at these protrusions is greater than that of other parts, thereby increasing the strength and rigidity of the inner wall, significantly reducing the possibility of deformation during use, and providing better support and stability.

[0023] 2. The tear structure of the present invention is designed in the shape of a long strip, with both ends connected to the two ends of the opening respectively, and a tear protrusion is provided at the connection. These designs improve the stability and tearability of the tear structure through different wall thickness distributions, while maintaining the overall strength and balance of the profile. In addition, the precise geometric dimensions of the "C"-shaped protrusion (center distance of 34.88mm to 35.18mm, outer circle diameter of 4.8mm to 5mm, inner circle diameter of 2.4mm to 2.6mm) ensure the structural stability of the profile, reduce the errors that may occur during the production process, and thus improve the consistency and overall quality of the product. Furthermore, the rectangular design of the cross-section of the profile body and the rounded corner design (radius of 4mm to 4.2mm) not only standardize the size and facilitate production and application, but also reduce stress concentration, avoid cracks and breakages during use, and improve durability and safety.

[0024] 3. The design of the long cantilever cross-section structure of the profile body of the utility model makes the ratio of the opening size to the profile body height greater than 3, which improves the bending resistance and rigidity of the profile and avoids deformation and cracking during processing. The precise opening protrusion size (diameter is 1.7mm to 1.9mm) provides better positioning and fixing effects, enhances overall stability, and facilitates the tearing operation, improving production efficiency and product quality. The mold design combined with the tearing process effectively solves the problems that are prone to occur in the extrusion process of the long cantilever cross-section structure, improves the stability of the opening size, and significantly improves the extrusion success rate of the product and the stability of the opening size, achieving the effect of high-quality and high-efficiency production.

[0030] To make the objectives, technical solutions, and advantages of the present disclosure more clearly apparent, embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings. The proportions of the components are not drawn to scale, and the proportions and dimensions shown in the accompanying drawings are not intended to limit the substantial technical solutions of the present disclosure. These embodiments do not describe all details in detail, nor do they limit the present disclosure to the specific embodiments described.

[0031] See also Figure 1-4 As shown, a steel shell tear profile includes a profile body, the cross-section of the profile body is a semi-closed shape with an opening on one side, the opening is provided with a tearable tear structure, and opening protrusions are provided at the connection between the two ends of the tear structure and the opening.

[0032] like Figure 1 In one embodiment shown, Figure 1 This is a schematic diagram of the untorn profile cross section of a steel shell tear profile of the utility model. The steel shell tear profile designed by the utility model has a unique design and functionality, and can show superior performance in various application scenarios. The cross section of the profile body presents a semi-closed shape with an opening on one side. This design not only improves the overall strength of the steel, but also provides great convenience for installation and fixation. A tear structure that can be torn is provided at the opening, and opening protrusions are provided at both ends of the tear structure and the connection between the opening. The tear structure is designed to be long and narrow, with both ends connected to the two ends of the opening respectively, and tear protrusions are provided at the connection. The thickness of these protrusions is greater than the wall thickness of the rest of the profile body, but their size is smaller than the wall thickness of the profile body.

[0033] The inner wall of the cross-section of the profile body is equipped with several "C"-shaped protrusions. These protrusions are thicker than the wall thickness of other parts, which can significantly enhance the internal support of the profile. One "C"-shaped protrusion is located on the side wall of the profile body opening, and the other is located on the top wall on the other side. The distance between the two centers is 34.88mm to 35.18mm, the outer diameter is 4.8mm to 5mm, and the inner diameter is 2.4mm to 2.6mm.

[0034] The profile body has a rectangular cross-section, with a length of 1103mm to 1103.6mm, a width of 49.4mm to 49.8mm, and a height of 49.7mm to 45.1mm. The corners of the profile body are rounded, with a radius of 4mm to 4.2mm. The cross-section is designed as a long cantilever structure, with a ratio of the opening size to the profile body height greater than 3. Furthermore, the diameter of the opening protrusion is 1.7mm to 1.9mm.

[0035] This steel shell tear-off profile is designed with functionality and structural strength in mind. Its semi-enclosed shape not only increases overall strength but also facilitates installation and fastening. The tear-off structure is designed as an elongated strip, making it easier to peel or open. The protrusions at each end of the tear-off structure not only enhance the structural integrity of the tear-off area but also prevent uncontrolled expansion during the tearing process.

[0036] The "C"-shaped protrusions within the profile body are designed to provide additional support and enhance the stability of the overall structure. Located on the side wall of the opening and the top wall on the other side, the two "C"-shaped protrusions are precisely designed with their center distance and diameter to ensure that they enhance internal support without compromising the strength of the profile.

[0037] In addition, the length, width and height of the profile body have been precisely designed to ensure that it can be used in different application scenarios. The rectangular cross-section design is not only easy to process and manufacture, but also meets various installation requirements. The rounded corners are designed to prevent damage to personnel and other equipment during transportation and installation, while also improving the aesthetics of the profile. The ratio of the opening size to the profile height is greater than 3, which ensures that the internal structure can be easily accessed in actual use, facilitating operation and maintenance. The diameter range design of the opening protrusion ensures that the best functional effect can be achieved during the tearing process, which will not affect the overall strength of the steel and can provide sufficient tearing convenience.

[0038] Overall, this steel shell tear-off profile is designed with full consideration for structural strength, ease of use, and safety. It is suitable for a variety of industrial and architectural applications and is an advanced profile product that combines functionality and practicality. In one embodiment, the profile has a cross-sectional area of ​​approximately 228 square millimeters, a straightness of less than or equal to 0.4 mm, a torsion of less than or equal to 0.4 mm / m, and a perpendicularity of less than or equal to 0.2 mm at both ends. The surface is smooth, free of obvious scratches, extrusion marks, cracks, peeling, corrosion, bubbles, and other defects, and the sawn surface is burr-free.

[0039] The distance from the center of the "C"-shaped protrusion to the outer wall is 5.2mm to 5.5mm, and the opening size is 11.4mm to 12.1mm. The wall thickness of the profile section is generally 1.14mm to 1.16mm. The top and bottom walls are arc-shaped with a radius of 110mm, and the side walls are also arc-shaped with a radius of 96mm. The bottom of the upper opening protrusion is 5.75mm to 6.05mm from the outer top wall, and the top of the lower opening protrusion is 8mm to 8.3mm from the outer bottom wall.

[0040] These detailed dimensions and design parameters ensure the reliability and safety of the steel shell tear profile in practical applications. First, the profile's cross-sectional area provides sufficient load-bearing capacity, suitable for applications requiring high strength. Strict control of straightness and torsion ensures the profile's stability and consistency over long distances. Controlled perpendicularity of the end faces ensures a tight fit during installation and connection, minimizing errors.

[0041] High surface quality requirements, such as smooth finish and absence of obvious defects, ensure the aesthetics and durability of the profiles during use. The absence of defects such as cracks, peeling, corrosion, and bubbles further enhances their suitability for use in harsh environments. The burr-free sawn surface reduces safety hazards during cutting and processing.

[0042] The "C"-shaped protrusion design provides additional internal support, reducing deformation of the profile under stress. The precise design of the distance from the center to the outer wall and the opening size further enhances its structural strength and stability.

[0043] The rounded top and bottom walls are not only aesthetically pleasing but also effectively disperse stress, reducing concentrated stress points and extending the profile's service life. The rounded side walls also enhance structural strength and aesthetics. The raised opening prevents uncontrolled tearing during the opening process, increasing safety and reliability.

[0044] In short, this steel shell tear-off profile combines structural strength, ease of use, safety, and aesthetics, making it suitable for a variety of industrial and architectural applications. Its precise dimensional design and high-quality manufacturing process ensure the product's reliability and durability in use, making it an advanced profile product that combines functionality and practicality.

[0045] In one embodiment, the cross-sectional area of ​​the profile is approximately 228 square millimeters, the straightness is less than or equal to 0.4 mm, the twist is less than or equal to 0.4 mm / m, the verticality of the end faces is less than or equal to 0.2 mm, the surface of the product is smooth, without obvious scratches, extrusion marks, cracks, peeling, corrosion, bubbles and other defects, and the sawn surface is burr-free. The distance from the center of the "C"-shaped protrusion to the outer wall is 5.2 mm to 5.5 mm, the opening size is 11.4 mm to 12.1 mm, the wall thickness of the profile section is generally 1.14 mm to 1.16 mm, the top and bottom walls are arc-shaped with a radius of 110 mm, and the side walls are also arc-shaped with a radius of 96 mm. The bottom of the upper opening protrusion is 5.75 mm to 6.05 mm away from the outer top wall, and the top of the lower opening protrusion is 8 mm to 8.3 mm away from the outer bottom wall.

[0046] like Figure 2 and Figure 3 In one embodiment shown, Figure 2 This is a schematic cross-sectional view of a steel shell tear profile of the utility model. Figure 3 This is a schematic diagram of the profile body structure of a steel shell tear profile of the utility model. The utility model designs a steel shell tear profile, which includes a profile body with a cross section in a semi-closed shape with an opening on one side. The inner wall of the cross section is specially provided with a number of "C"-shaped protrusions, and the wall thickness of these "C"-shaped protrusions is greater than the wall thickness of the rest of the section. One of the "C"-shaped protrusions is located on the side wall of the opening of the profile body, and the other is located on the top wall on the other side. The distance between the centers of the two is 34.88mm to 35.18mm, the outer diameter is 4.8mm to 5mm, and the inner diameter is 2.4mm to 2.6mm. In addition, the thickness of the opening protrusion is greater than the wall thickness of the rest of the profile body, and the diameter of the opening protrusion is 1.7mm to 1.9mm.

[0047] In order to improve the stability of the opening size of the steel shell product, especially when the ratio of the opening size to the product depth size exceeds 3 times, the structure belongs to a long cantilever cross-section structure. Since the strength of the profile extrusion die cannot meet the extrusion requirements, it is easily affected by temperature and pressure during the extrusion process, resulting in extrusion deviation, breakage, etc. of the mold, which in turn leads to the scrapping of the mold. In this case, the extrusion molding effect is poor, the product extrusion success rate is low, and the stability of the cross-section opening size is poor. In order to overcome the shortcomings of this cross-section structure, a tearing process is introduced into the mold design. Specifically, the mold extrusion die is designed as a sealing structure with a thinner wall thickness at the connection. After the profile is extruded out, the added sealing position can be torn open manually or by machine equipment, thereby achieving the effect of stable opening size and high extrusion success rate.

[0048] The profile has a rectangular cross-section, measuring 1103mm to 1103.6mm in length, 49.4mm to 49.8mm in width, and 49.7mm to 50.1mm in height. To enhance structural integrity, the corners are rounded with a radius of 4mm to 4.2mm. This profile was designed not only for structural strength but also for aesthetics and practicality.

[0049] Overall, the introduction of the tearing process significantly improves the extrusion success rate and the stability of the opening dimensions, resolving the issues inherent in the extrusion molding process with traditional long cantilever cross-section structures. This design meticulously addresses every detail of the profile, ensuring production stability and product quality. This innovative design approach not only improves production efficiency but also effectively reduces mold scrap rates, providing reliable technical support for the production of steel shell products.

[0050] like Figure 4 In one embodiment shown, Figure 4 This is an enlarged partial cross-section of an untorn steel shell profile according to the present invention. This steel shell profile has an opening on one side of the semi-enclosed cross-section of the profile body. This opening is designed with a tearing structure that can be torn open. The tearing structure is long and connected to the ends of the opening. At the connection points of the tearing structure, there are opening protrusions. These protrusions are smaller than the wall thickness of the profile body and are teardrop-shaped or circular.

[0051] This design has many benefits. First, the semi-closed shape design enhances the overall strength of the profile, making it more sturdy and durable during application. The opening is designed as a tearable tear structure, so that in actual use, the user can easily tear off the required part, which provides great flexibility and convenience in installation and operation. Secondly, the tear structure is long and has opening protrusions at the connection points at both ends. The presence of these protrusions effectively enhances the structural integrity of the tear area, prevents the problem of uncontrolled expansion of the tear during the tearing process, and improves the safety of use. The tear protrusion is designed to be tear-drop-shaped or circular, so that the tear area is more evenly stressed, thereby reducing stress concentration and improving the durability of the profile. Finally, this design is not only easy to manufacture and process, but also meets the needs of a variety of industrial and architectural application scenarios. Through scientific structural design and precise dimensional control, it ensures the efficiency and reliability of the product in use. It is an advanced profile product that is both functional and practical.

[0052] In summary, the utility model relates to a steel shell tear profile, which adopts a variety of innovative processes in its design, including a semi-enclosed cross-section, a tear structure and a "C"-shaped protrusion. The cross-section is a semi-enclosed shape with an opening on one side, which enhances the overall strength and ease of installation. The tear structure is long and narrow, with opening protrusions at both ends, and the thickness is greater than the wall thickness of the rest of the part to prevent uncontrolled expansion during the tearing process. The "C"-shaped protrusion on the inner wall increases the internal support force and improves the structural stability. Precise dimensional design, such as a length of 1103mm to 1103.6mm, a width of 49.4mm to 49.8mm, and a height of 49.7mm to 50.1mm, as well as detailed parameters of the fillet and protrusion, ensure the product's processing and manufacturing and applicability in various application scenarios. In addition, the tear process significantly improves the extrusion success rate and the stability of the opening size, and reduces the mold scrap rate. This profile combines structural strength, ease of use, safety and aesthetics, and is suitable for a variety of industrial and architectural application scenarios. It is an advanced profile product that combines functionality and practicality.

[0053] The present invention is not limited to the above-mentioned embodiments. Regardless of any changes in its shape or material composition, any structural design provided by the present invention is a variation of the present invention and should be considered within the scope of protection of the present invention.
