Description

Technical Field

[0001] This utility model relates to the field of automotive repair equipment technology, specifically a special tool for fabricating tubular sheet metal parts. Background Technology

[0002] Tubular sheet metal fabrication refers to a processing technique that uses hand tools to bend steel plates into tubular structures. It is commonly used in the fabrication of sheet metal parts such as automotive mufflers and exhaust pipes.

[0003] Sheet metal parts often require manual fabrication due to damage from traffic accidents, corrosion, rust, shortage of spare parts, high replacement costs, and the need for personalized modifications. Tubular sheet metal parts, such as car mufflers and exhaust pipes, are particularly widely used and can be repaired or custom-made using either partial or modular fabrication methods.

[0004] In traditional tubular sheet metal fabrication, a steel ingot is usually clamped in a bench vise. During the hammering process, the steel ingot is often tilted, slipped, or even detached due to its insecure fixation, resulting in low efficiency and unreliable product quality.

[0005] A search revealed no reports of specialized tools for fabricating tubular sheet metal parts. Based on this, this invention addresses the current lack of such tools through innovative research and, through repeated verification, provides a specialized tool for fabricating tubular sheet metal parts, aiming to achieve greater practical value. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a special tool for manufacturing tubular sheet metal parts, which addresses the need for manual manufacturing of tubular sheet metal parts using special tools in situations such as automobile body rust, parts shortage, and personalized modification requirements.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a special tool for fabricating tubular sheet metal parts, including one working steel ingot, two fixing steel blocks, and one fixing steel plate. The working steel ingot is a circular, solid steel column with a curved middle section, and its diameter and curvature angle are matched with the tubular sheet metal part to be processed. The fixing steel plate is welded to the bottom of the front end of the working steel ingot, and the two fixing steel blocks are symmetrically welded to both sides of the middle section of the working steel ingot. The fixing steel blocks are welded before the curved part of the working steel ingot and to the upper middle part of the working steel ingot. The length distance between the fixing steel blocks and the fixing steel plate is less than the jaw width of the bench vise used with them, and the height distance between the fixing steel blocks and the fixing steel plate is matched with the jaw height of the bench vise used with them.

[0009] The above technical solution involves welding a fixing steel plate to the bottom front end of the working steel ingot, and symmetrically welding fixing steel blocks to the upper middle section of the working steel ingot. In use, the working steel ingot is clamped in a bench vise, with the fixing steel plate positioned at the lower end of one end of the vise jaws and the fixing steel blocks at the upper end of the other end. This solves the problem of insecure fixing of the working steel ingot, facilitating the fabrication of tubular sheet metal parts. It is simple and convenient to use, sturdy and durable, significantly improving work efficiency and ensuring processing quality. It can meet customized, personalized, and professional needs, and has promising application prospects.

[0010] Preferably, the thickness of the fixing steel block and the fixing steel plate is greater than or equal to 10 mm.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. It can fully meet the manufacturing requirements of tubular sheet metal parts.

[0013] 2. The upper part is welded with a steel block, and the lower part is welded with a thick steel plate, which facilitates the use of a bench vise for fixation and ensures operational stability.

[0014] 3. It can meet customized, personalized, and professional needs and has a wide range of applications.

[0015] 4. Practical and durable, it can significantly improve work efficiency while ensuring processing quality. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] See Figure 1 This utility model provides a special tool for fabricating tubular sheet metal parts, comprising four parts: a working steel ingot 1, two fixing steel blocks 2, and a fixing steel plate 3. The working steel ingot 1 is a circular, solid steel column with a curved center, its diameter and curvature angle matching the tubular sheet metal part to be processed. The fixing steel blocks 2 and the fixing steel plate 3 are thick steel plates welded to the working steel ingot 1 to form an integral structure. The fixing steel plate 3 is welded to the bottom of the front end of the working steel ingot 1, and the two fixing steel blocks 2 are symmetrically welded to both sides of the middle section of the working steel ingot 1. The fixing steel blocks 2 are welded before the curved part of the working steel ingot 1 and to the upper middle part of the working steel ingot 1. The length distance between the fixing steel blocks 2 and the fixing steel plate 3 is less than the jaw width of the bench vise 4 used with them, and the height distance between the fixing steel blocks 2 and the fixing steel plate 3 matches the jaw height of the bench vise 4. When in use, the bench vise 4 clamps the working steel ingot 1, and the fixing steel plate 3 is stuck at the lower part of one end of the jaws of the bench vise 4, while the fixing steel block 2 is stuck at the upper part of the other end of the jaws of the bench vise 4. This can solve the problem of the working steel ingot 1 not being securely fixed, making it convenient to manufacture tubular sheet metal parts.

[0025] To ensure the robustness and durability of the special tools used in the fabrication of tubular sheet metal parts according to this utility model, the fixing steel block 2 and the fixing steel plate 3 are made of thick steel plates with a thickness of ≥10mm.

[0026] In addition, a series of steel ingots with different diameters and bending angles can be selected to make a set of special tools for the fabrication of tubular sheet metal parts in various sizes and specifications, so as to facilitate the fabrication of tubular sheet metal parts of different sizes.

[0027] The length and height distance between the fixed steel block 2 and the fixed steel plate 3 welded to the working steel ingot 1 can be customized to make multiple series of complete sets of special tools based on tubular sheet metal parts, depending on the different models of bench vises available on the market. Alternatively, it can be customized according to the existing bench vise dimensions of the customer.

[0028] The working process of this utility model is as follows:

[0029] This utility model provides a special tool for fabricating tubular sheet metal parts. It consists of a solid cylindrical working steel ingot bent into a suitable shape, a fixing steel plate, and a fixing steel block, all connected by welding to form an integral structure. When fabricating the tubular sheet metal part, first loosen the bench vise, place the working steel ingot body into the vise jaws, and move the special tool from one side of the vise to the other, so that the lower welded fixing steel plate is positioned on the lower part of one side of the vise jaws, and the upper welded fixing steel block is positioned on the upper part of the other side of the vise jaws. Tighten the vise. Place the sheet metal part on the working steel ingot and perform bending, hammering, and other operations; the sheet metal part will then exhibit the desired deformation.

[0030] Thanks to the fixing steel plates and blocks welded to the upper and lower parts of the steel ingot, the special tool is securely fixed to the bench vise, solving the problem of tilting, sliding, or even detachment that occurs during hammering due to an unstable fixing of the steel ingot. The special tool made from tubular sheet metal parts provided by this invention is highly practical, sturdy, and durable. It can significantly improve work efficiency, ensure the quality of processed products, meet customized, personalized, and professional needs, has a wide range of applications, and has promising prospects.
