Description

Technical Field

[0001] This utility model relates to the field of sheet metal welding technology, specifically to a ferrous metal sheet metal welding component designed to prevent leaks in welding. Background Technology

[0002] In the manufacturing process of ferrous metal sheet metal welded parts, the accuracy of welding positioning directly affects the welding quality. Currently, traditional ferrous metal sheet metal welded parts have many shortcomings in the welding positioning stage. After blackening treatment, many welded parts lack effective marking methods, resulting in low differentiation between the installation position and the surrounding area. When installing a second workpiece, operators find it difficult to accurately judge the welding installation position visually, leading to frequent inaccurate positioning. This positioning error easily causes incomplete welding, resulting in weak connections and structural instability during subsequent use, seriously affecting the normal operation of equipment, and may even lead to equipment failure, increasing maintenance costs and downtime. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a ferrous metal sheet metal welding component that prevents weld leakage, thus solving the problems mentioned in the background art.

[0004] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0005] A ferrous sheet metal welding component designed to prevent incomplete welding includes: a first workpiece and a second workpiece. The first workpiece has a protective film, which is used to cover the mounting position of the first workpiece during blackening treatment, so as to indicate the welding mounting position of the second workpiece by color difference. The first workpiece has a mounting hole and a foolproof hole at the mounting position, and the second workpiece has a limiting foot and a foolproof foot. The limiting foot and the foolproof foot are interlocked with the mounting hole and the foolproof hole to limit the installation of the second workpiece at the mounting position. The first workpiece and the second workpiece are fixed by welding after being limited and installed.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the protective film is applied to the first workpiece and covers the mounting position during the blackening process; the protective film is removed when the second workpiece is installed.

[0008] The beneficial effects of adopting the above-mentioned further solutions are:

[0009] During the blackening process, the chemical solution used is corrosive. The protective film effectively covers the mounting position of the first workpiece, preventing the chemical solution from corroding the mounting position and protecting its surface quality and dimensional accuracy. After blackening, a clear color difference forms between the mounting position and the blackened area. When installing the second workpiece, the protective film is removed. This color difference allows for a direct and accurate indication of the welding position of the second workpiece, preventing incomplete welding due to inaccurate positioning, improving welding accuracy and reliability, and ensuring stable weld quality.

[0010] Furthermore, the mounting hole and the foolproof hole are provided through the first workpiece.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The mounting holes and anti-fool holes extending through the first workpiece allow the limiting feet and anti-fool feet of the second workpiece to be fully inserted, increasing the insertion depth and stability. This deep insertion method better restricts the movement of the second workpiece in multiple directions, providing more reliable positioning for the second workpiece before welding, reducing welding deformation caused by workpiece shaking during welding, further enhancing the overall structural stability of the welded parts, and ensuring welding quality.

[0013] Furthermore, the limiting foot and the foolproof foot are disposed at the edge of the second workpiece.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] Positioning the limiting feet and foolproof feet at the edge of the second workpiece facilitates alignment and insertion with the mounting holes and foolproof holes on the first workpiece during installation. This layout allows installers to more intuitively observe and adjust the position of the second workpiece, improving installation efficiency. Simultaneously, the edge placement helps disperse stress during insertion, reducing damage to the second workpiece caused by localized stress concentration and extending its service life.

[0016] Furthermore, the first workpiece is also equipped with a first bolt and a second bolt, which are used for the installation and fixation of the first workpiece.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The first and second bolts provide a convenient and reliable connection method for installing and securing the first workpiece. In practical applications, a suitable installation location can be selected according to specific needs, and the first workpiece can be firmly installed on other equipment or structures using bolts. This installation method has high flexibility and adaptability, can meet different working environments and installation requirements, and ensures the stability and reliability of the entire welded component in actual use.

[0019] Furthermore, the welding fixation is achieved by welding the first workpiece and the second workpiece at the mounting position.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] Welding at the mounting position allows for a direct and secure connection between the first and second workpieces, which are already in place, forming a single unit. This welding method fully utilizes the high-strength connection characteristics of welding, giving the welded parts better load-bearing capacity and resistance to deformation under external forces. Furthermore, the welding method is simple, direct, and easy to operate, improving production efficiency and reducing production costs.

[0022] This utility model provides a ferrous metal sheet metal welding component designed to prevent incomplete welding. It offers the following advantages:

[0023] A protective film is applied to the first workpiece, covering the mounting position during the blackening process. After blackening, a clear color difference forms between the mounting position and the blackened area, providing a direct and precise indication of the welding position for the second workpiece. This avoids incomplete welding due to inaccurate positioning, improving welding accuracy and reliability, and ensuring consistent weld quality. Applying the protective film to the mounting position before blackening prevents corrosion and contamination from chemicals during the process. Blackening typically involves corrosive chemical solutions; the protective film effectively isolates these solutions from contact with the mounting position, protecting its surface quality and dimensional accuracy, ensuring successful installation of the second workpiece, and extending the weld's lifespan.

[0024] The first workpiece has a mounting hole and a foolproof hole at its mounting position, while the second workpiece has a limit foot and a foolproof foot. The limit foot and foolproof foot interlock with the mounting hole and the foolproof hole. The foolproof design ensures that the second workpiece can only be installed in the correct orientation and position on the mounting position of the first workpiece, effectively preventing installation errors caused by incorrect installation orientation or positional deviation, reducing debugging time during installation, and improving installation efficiency.

[0025] By connecting the limiting feet and anti-fooling feet to the mounting holes and anti-fooling holes, the second workpiece is initially positioned and limited on the first workpiece. This limiting method restricts the movement of the second workpiece in multiple directions, ensuring it is in a relatively stable position before welding. During subsequent welding, this guarantees the relative position of the welded parts remains fixed, reducing welding deformation and enhancing the overall structural stability of the welded component.

[0033] 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.

[0034] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0035] Example 1

[0036] A ferrous sheet metal welding component designed to prevent incomplete welding includes: a first workpiece 1 and a second workpiece 2. The first workpiece 1 is provided with a protective film 101, which is used to cover the mounting position 104 of the first workpiece 1 during blackening treatment, so as to indicate the welding mounting position of the second workpiece 2 by means of color difference. The first workpiece 1 is provided with a mounting hole 105 and a foolproof hole 106 at the mounting position 104. The second workpiece 2 is provided with a limiting foot 201 and a foolproof foot 202, which are inserted into the mounting hole 105 and the foolproof hole 106 to limit the installation of the second workpiece 2 at the mounting position 104. The first workpiece 1 and the second workpiece 2 are fixed by welding after being limited and installed.

[0037] Example 2

[0038] To further optimize the performance and effectiveness of anti-slip welding ferrous metal sheet metal welded parts, for example, such as Figures 1 to 3 As shown, this utility model also includes:

[0039] A protective film 101 is applied to the first workpiece 1 and covers the mounting position 104 during the blackening process. The protective film 101 is removed when the second workpiece 2 is installed. During the blackening process, the chemical solution used for blackening is corrosive. The protective film 101 effectively covers the mounting position 104 of the first workpiece 1, preventing the chemical solution from corroding the mounting position 104 and protecting the surface quality and dimensional accuracy of the mounting position 104. After the blackening process, a clear color difference is formed between the mounting position 104 and the blackened area. When the second workpiece 2 is installed, the protective film 101 is removed. This color difference allows for a direct and accurate indication of the welding mounting position 104 of the second workpiece 2, avoiding incomplete welding due to inaccurate positioning, improving the accuracy and reliability of welding, and ensuring the stable quality of the welded parts.

[0040] Mounting hole 105 and anti-fool hole 106 penetrate the first workpiece 1, allowing the limiting foot 201 and anti-fool hole 202 of the second workpiece 2 to be fully inserted, increasing the insertion depth and stability. This deep insertion method better restricts the movement of the second workpiece 2 in multiple directions, providing more reliable positioning for the second workpiece 2 before welding, reducing welding deformation caused by workpiece shaking during welding, further enhancing the overall structural stability of the welded part, and ensuring welding quality.

[0041] The limiting foot 201 and the foolproof foot 202 are located at the edge of the second workpiece 2. Positioning the limiting foot 201 and the foolproof foot 202 at the edge of the second workpiece 2 facilitates alignment and insertion with the mounting holes 105 and foolproof holes 106 on the first workpiece 1 during installation. This layout allows installers to more intuitively observe and adjust the position of the second workpiece 2, improving installation efficiency. Simultaneously, the edge placement helps to disperse stress during insertion, reducing damage to the second workpiece 2 caused by localized stress concentration and extending its service life.

[0042] The first workpiece 1 is also equipped with a first bolt 102 and a second bolt 103. The first bolt 102 and the second bolt 103 are used for the installation and fixation of the first workpiece 1, providing a convenient and reliable connection method. In practical applications, a suitable installation position 104 can be selected according to specific needs, and the first workpiece 1 can be firmly installed on other equipment or structures using bolts. This installation method has high flexibility and adaptability, can meet different working environments and installation requirements, and ensures the stability and reliability of the entire welded component in actual use.

[0043] Welding fixation is achieved by welding the first workpiece 1 and the second workpiece 2 at the mounting position 104. Welding fixation at the mounting position 104 can directly and firmly connect the first workpiece 1 and the second workpiece 2, which are already in the limiting installation position, to form a whole. This welding method can fully utilize the high-strength connection characteristics of welding, giving the welded parts better load-bearing capacity and deformation resistance when subjected to external forces. At the same time, the welding fixation method is simple and direct, easy to operate, and can improve production efficiency and reduce production costs.

[0044] Working principle:

[0045] A protective film 101 is affixed to the first workpiece 1, covering the mounting position 104 of the first workpiece 1 in preparation for subsequent blackening treatment. Its working principle is that the protective film 101 is used to cover the mounting position 104 of the first workpiece 1 during the blackening treatment to prevent the mounting position 104 from being blackened. Subsequently, the color difference between the mounting position 104 and the blackened area indicates the welding mounting position 104 of the second workpiece 2.

[0046] The first workpiece 1, covered with a protective film 101, is blackened. Since the protective film 101 covers the mounting position 104, the blackening process does not affect the area of ​​the mounting position 104. When installing the second workpiece 2, the protective film 101 covering the mounting position 104 is removed, exposing the mounting position 104. The second workpiece 2 is placed at the mounting position 104 of the first workpiece 1, allowing the limiting foot 201 and the foolproof foot 202 on the second workpiece 2 to interlock with the mounting hole 105 and the foolproof hole 106 on the first workpiece 1, thus achieving the limited installation of the second workpiece 2 at the mounting position 104. Its working principle is that the mutual cooperation between the mounting hole 105 and the foolproof hole 106 and the limiting foot 201 and the foolproof foot 202 prevents incorrect installation of the second workpiece 2, ensuring that the second workpiece 2 is accurately installed at the mounting position 104.

[0047] The first workpiece 1 and the second workpiece 2 are welded together at mounting position 104 to fix them together. The working principle is to firmly connect the first workpiece 1 and the second workpiece 2, which are already in the limiting installation position, through welding to form a stable welded component. The first workpiece 1 is then installed and fixed using the first bolt 102 and the second bolt 103 installed on it, completing the installation of the entire anti-slip weld ferrous metal sheet metal welded component.
