Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending processing technology, specifically to a manual bending tool for thin sheet metal with adjustable angle. Background Technology
[0002] Thin metal sheets are a type of metal material with relatively small thickness, usually made through processes such as rolling, forging, and stretching, and have uniform thickness and large planar dimensions.
[0003] When bending thin metal sheets, especially when the number of workpieces is small, their dimensions are small, and the required precision is not high, using precise processing equipment would be time-consuming, labor-intensive, and wasteful of resources. Most existing bending tools require the operator to measure angles using angle gauges, which is inconvenient and may result in bending angles that are too large or too small, and the bending radius (R-angle) cannot be controlled. This paper proposes a manual bending tool that allows adjustment and fixing of angle settings according to requirements, and allows control of the bending radius of the sheet metal by adjusting the size of the R-angle plate on the tool.

[0020] 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.
[0021] Please see Figure 1-4This utility model discloses a manual bending tool for thin sheet metal with adjustable angle, including a fixed base plate 1, a bending plate 2, an R-angle plate 3, a hinge 4, an angle adjustment and limiting device 5, a first screw 6, a second screw 7, and a fixing member 8. The bending plate 2 is provided at the bottom of the fixed base plate 1, the R-angle plate 3 is provided between the fixed base plate 1 and the bending plate 2, the hinge 4 is provided between the fixed base plate 1 and the bending plate 2, and the angle adjustment and limiting device 5 is provided between the fixed base plate 1 and the bending plate 2.
[0022] Specifically, the surfaces of both the fixed base plate 1 and the bending plate 2 are provided with first screws 6.
[0023] In this embodiment, a fixed base plate 1 and a bending plate 2 are provided. The fixed base plate 1 serves as the basic support component of the entire tool, providing a stable support surface so that the entire bending process can be carried out on a fixed platform. The bending plate 2 is the component that actually performs the bending operation. Supported by the fixed base plate 1, the operator can manually apply force to bend the bending plate 2 relative to the fixed base plate 1, thereby processing the thin sheet material placed between the two. The bending plate 2 works in conjunction with the radius plate 3. By selecting a suitable radius plate 3 and positioning it on the fixed base plate 1, the radius angle of the bent sheet material can be controlled, resulting in a more aesthetically pleasing bent sheet material that is less prone to cracking.
[0024] Specifically, the surfaces of the fixed base plate 1 and the angle adjustment and limiting device 5 are all provided with second screws 7.
[0025] In this embodiment, by setting an angle adjustment and limiting device 5, the user can adjust the bending angle of the bending plate 2 relative to the fixed base plate 1 according to specific needs. This function enables the tool to adapt to the precise bending angle requirements of different workpieces, improving processing flexibility and applicability. When the bending plate 2 reaches the predetermined bending angle, the angle adjustment and limiting device 5 can automatically or manually limit the bending angle to prevent it from being too large. This function helps prevent material damage caused by excessive bending, ensuring the safety and stability of the processing. The addition of the angle adjustment and limiting device 5 enables this thin sheet manual bending tool to not only have basic bending functions.
[0026] Specifically, the surface of the fixed base plate 1 is provided with a fixing member 8.
[0027] In this embodiment, a fixing member 8 is provided. The main function of the fixing member 8 is to securely position the R-angle plate 3 onto the working surface of the fixed base plate 1. The R-angle plate 3 is a key component used to control the R-angle size when the plate is bent, and the fixing member 8 ensures the stability and accuracy of the R-angle plate 3 during the processing.
[0028] Specifically, both the first screw 6 and the second screw 7 are made of stainless steel.
[0029] In this implementation scheme, the first screw 6 and the second screw 7 are made of stainless steel. Stainless steel has excellent corrosion resistance, allowing it to be used for extended periods in harsh environments such as humid and acidic / alkaline conditions without rusting or corroding. This ensures that the screws maintain a stable tightening effect during tool use, preventing loosening or damage due to corrosion. Stainless steel screws also possess high strength, capable of withstanding significant tensile and compressive forces. In thin sheet metal hand bending tools, the screws need to withstand the connecting force between the bending plate and the fixed base plate, as well as the tightening force of the angle adjustment and limiting devices. The high strength of the stainless steel screws ensures a secure connection between these components, improving the overall durability and service life of the tool.
[0030] Specifically, both the fixed base plate 1 and the bent plate 2 are L-shaped angle members.
[0031] In this embodiment, by setting up L-shaped corner brackets, which have a large contact area and stable geometry, a robust support base can be provided for the entire tool. The design of the L-shaped corner brackets makes it easier to position and fix the base plate 1 and the bent plate 2 in space.
[0032] In use, the first step is to connect the fixed base plate 1 and the bending plate 2 using the hinge 4 and the first screw 6. The second step is to position the angle adjustment and limiting device 5 on the fixed base plate 1, adjust the zero position to be flush with the working surface of the fixed base plate 1, and then fix it with the second screw 7. The third step is to select a suitable R-angle plate 3 and position it on the working surface of the fixed base plate 1 through the fastener 8.
[0033] In summary, this adjustable-angle thin sheet metal manual bending tool, by setting the angle adjustment and limiting device 5, can limit the bending angle to prevent excessive bending angle from damaging the material. By setting the R-angle plate 3, the tool can control the R-angle of the bent sheet metal by adjusting the size of the installed R-angle plate 3, resulting in a more aesthetically pleasing bent sheet metal and preventing cracking of the thin sheet metal. By setting the fixed base plate 1, this tool is compact, easy to use and store, and can be fixed to a tabletop using the fixed base plate 1 and clamps, or fixed using a bench vise.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
