Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a metal band saw. Background Technology

[0002] A metal band saw is a mechanical device used for cutting metal materials. Vertical metal band saws are relatively simple to operate. The workpiece is placed on the worktable and moved manually or automatically to align the cutting line with the teeth of the saw blade. The saw blade rotates to cut, and metal chips are discharged through the hollow structure of the saw blade during the cutting process. The advantages of this type of band saw include high cutting speed, precise cutting, and a small cutting width. It is suitable for various metal materials, such as steel, aluminum, copper, and stainless steel.

[0003] The existing technology has at least the following problems: whether cutting large or small workpieces, the cutting is carried out on the same worktable. However, for large workpieces, the worktable may be too small and cannot fully support the workpiece, while for small workpieces, the worktable may be too large and inconvenient for workers to operate at close range. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a metal band saw. This invention allows for easy adjustment of the worktable according to the size of the workpiece, effectively improving the performance of the metal band saw.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a metal band saw machine, including a workbench, a band saw machine body on one side of the workbench, and an extension workbench, which is hinged to the workbench through a rotating plate. The rotating plate is provided with an arc-shaped limiting hole, and a positioning bolt is provided in the arc-shaped limiting hole. The inner end of the positioning bolt is set on the workbench, and the outer end of the positioning bolt is provided with a locking handle.

[0006] As an optimization, the cross-section of the extended worktable is inverted "L" shape, and the top of the extended worktable is provided with a saw groove that matches the band saw body. By setting the saw groove, the saw blade of the band saw body can be accommodated, making it convenient to cut small workpieces.

[0007] As an optimization, the inner side of the extended workbench is equipped with two sets of protective plates, which are respectively set on both sides of the saw groove. By setting up protective plates, the saw blade of the band saw body can be shielded, preventing the operator from accidentally touching the saw blade.

[0008] As an optimization, the first end of the rotating plate is fixedly connected to the extended worktable, and the second end of the rotating plate is hinged to the worktable via a pivot. By setting the pivot and the arc-shaped limiting hole, the stability of the rotating plate can be ensured.

[0009] As an optimization, a stop bar is provided at the second end of the rotating plate, and two sets of limiting bolts that cooperate with the stop bar are provided on the worktable. The two sets of limiting bolts are respectively located on both sides of the stop bar. By setting the stop bar and limiting bolts, the maximum rotation angle of the rotating plate can be limited, preventing the rotating plate from rotating excessively. This makes it convenient for the operator to adjust the rotating plate to be horizontal or vertical. It can also be used with the locking handle to lock the rotating plate, ensuring the stability of the extended worktable during operation.

[0010] As an optimization, the worktable is equipped with adjustment holes, and a T-shaped slider slides inside the adjustment holes. The screw of the limit bolt passes through the adjustment hole and connects to the T-shaped slider. By setting the adjustment holes and T-shaped sliders, the position of the limit bolt can be finely adjusted. This serves two purposes: first, it avoids installation errors, ensuring that the stops on both sets of rotating plates can simultaneously abut against the limit bolt; second, it allows the maximum rotation angle of the rotating plates to be changed according to cutting needs, thus adjusting the working position of the extended worktable.

[0011] As an optimization, the bottom of the worktable is equipped with support legs. By setting up support legs, the worktable can be stably supported, facilitating workpiece cutting.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating a rotating plate and an extended worktable, the position of the extended worktable can be adjusted according to the size of the workpiece. When cutting large workpieces, the extended worktable can be positioned horizontally to increase its area, facilitating support for cutting large workpieces. When cutting small workpieces, the extended worktable can be positioned vertically with its sides facing upwards, allowing for close-range cutting operations. The inclusion of arc-shaped limiting holes, positioning bolts, and locking handles serves two purposes: firstly, the rotating plate can be locked during cutting, thus securing the position of the extended worktable and ensuring its stability, preventing wobbling and potential hazards; secondly, the tightening and loosening of the locking mechanism allows for easy adjustment by the operator. This invention not only allows for worktable adjustment based on workpiece size but also provides convenient adjustment, effectively improving the performance of the metal band saw.

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0018] Example 1

[0019] Figure 1 and Figure 2 As one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a metal band saw includes a workbench 1, a band saw body 2 on one side of the workbench 1, and an extension workbench 3. The two ends of the extension workbench 3 are respectively hinged to the two ends of the workbench 1 through a rotating plate 4. The rotating plate 4 is provided with an arc-shaped limiting hole 5, and a positioning bolt is provided in the arc-shaped limiting hole 5. The inner end of the positioning bolt is set on the workbench 1, and the outer end of the positioning bolt is provided with a locking handle 6. By setting up a rotating plate 4 and an extended worktable 3, the position of the extended worktable 3 can be adjusted according to the size of the workpiece. When cutting large workpieces, the extended worktable 3 can be placed in a horizontal position, thereby increasing the area of ​​the worktable 1 and facilitating the cutting of large workpieces. When cutting small workpieces, the extended worktable 3 can be placed in a vertical position, with its side facing upwards, making it convenient for operators to operate the cutting. By setting up an arc-shaped limiting hole 5, positioning bolts, and a locking handle 6, it is possible to lock the rotating plate 4 during cutting, thereby locking the position of the extended worktable 3, ensuring the stability of the extended worktable 3, preventing the extended worktable 3 from shaking and avoiding danger. Secondly, it is easy to loosen and tighten the handle, making it convenient for operators to adjust the extended worktable 3.

[0020] like Figure 1 and Figure 2 As shown, the cross-section of the extended worktable 3 is inverted "L" shape, and the top of the extended worktable 3 is provided with a saw groove 7 that matches the band saw body 2. By setting the saw groove 7, the saw blade of the band saw body 2 can be accommodated, which is convenient for cutting small workpieces.

[0021] like Figure 2 As shown, the inner side of the extended workbench 3 is equipped with two sets of protective plates 8, which are respectively set on both sides of the saw groove 7. By setting the protective plates 8, the saw blade of the band saw body 2 can be blocked, preventing the operator from accidentally touching the saw blade.

[0022] like Figure 1 and Figure 2 As shown, the first end of the rotating plate 4 is fixedly connected to the extended worktable 3, and the second end of the rotating plate 4 is hinged to the worktable 1 via a rotating shaft 9. The center of the arc-shaped limiting hole 5 is the rotating shaft 9. By setting the rotating shaft 9 and the arc-shaped limiting hole 5, the stability of the rotating plate 4 can be ensured.

[0023] like Figure 1and Figure 2 As shown, a stop bar 10 is provided at the second end of the rotating plate 4, and two sets of limiting bolts 11 that cooperate with the stop bar 10 are provided on the worktable 1. The two sets of limiting bolts 11 are respectively located on both sides of the stop bar 10. By setting the stop bar 10 and the limiting bolts 11, the maximum rotation angle of the rotating plate 4 can be limited, preventing the rotating plate 4 from rotating excessively. This makes it convenient for the operator to adjust the rotating plate 4 to be horizontal or vertical. It can also be used in conjunction with the locking handle 6 to lock the rotating plate 4, ensuring the stability of the extended worktable 3 during operation.

[0024] like Figure 1 and Figure 2 As shown, the worktable 1 is provided with an adjustment hole 12, which is an oblong hole. A T-shaped slider 13 is slidably provided on the inner side of the adjustment hole 12. The screw of the limiting bolt 11 passes through the adjustment hole 12 and is connected to the T-shaped slider 13. By setting the adjustment hole 12 and the T-shaped slider 13, the position of the limiting bolt 11 can be finely adjusted. First, it can avoid installation errors and ensure that the stop bars 10 on the two sets of rotating plates 4 can simultaneously abut against the limiting bolt 11. Second, it can change the maximum rotation angle of the rotating plate 4 according to the cutting needs and adjust the working position of the extended worktable 3.

[0025] like Figure 1 and Figure 2 As shown, the bottom of the worktable 1 is provided with support legs 14. By providing support legs 14, the worktable 1 can be stably supported, facilitating workpiece cutting.

[0026] like Figure 1 As shown, when cutting large workpieces, the operator keeps the extended worktable 3 horizontal, with the stop bar 10 abutting against a set of limit bolts 11. The top of the extended worktable 3 is flush with the worktable 1, thereby increasing the area of ​​the worktable 1 and facilitating the cutting of large workpieces; as shown Figure 2 As shown, when cutting small workpieces, the operator loosens the locking handle 6 and rotates the extended worktable 3 so that the stop bar 10 abuts against another set of limit bolts 11. At this time, the extended worktable 3 is in a vertical position with its side facing upwards. The saw blade of the band saw body 2 is located in the saw groove 7 and between the two sets of protective plates 8. The operator tightens the locking handles 6 on both sides to lock the rotating plate 4 and the extended worktable 3. Then, the operator can cut smaller workpieces on the side of the extended worktable 3. This utility model can adjust the worktable according to the size of the workpiece and is easy to adjust, effectively improving the performance of the metal band saw.
