Technical Field

[0001] This invention relates to the field of cutting machine tool technology, and in particular to a multi-purpose copper band saw machine tool. Background Technology

[0002] Patent document CN217666866U (A Band Saw) discloses a band saw driven by a saw wheel to perform cutting operations. As can be seen from the specification and drawings, the cutting segment of the band saw is a straight line or a straight shape, and can only cut straight structures from materials. However, with the diversification of sheet metal structures, the sheets need to be cut into arc or semi-circular structures. Existing band saws are difficult to cut arc or semi-circular structures. Of course, cutting can also be done by laser cutting or gas cutting equipment, but the above equipment is too expensive. In addition, laser cutting or gas cutting equipment can only cut iron or steel materials, and is not suitable for materials such as copper, aluminum or wood. Summary of the Invention

[0003] The purpose of this invention is to provide a versatile copper band saw machine tool. The cutting shape adjustment mechanism can switch the band saw from a straight line to an arc shape, thereby cutting the plate into arc or semi-circular shapes.

[0016] In some embodiments, the cutting shape adjustment mechanism further includes a rotatable auxiliary turntable located on the side of the band saw away from the first turntable;

[0017] Auxiliary turntables are provided on both sides of the first turntable.

[0018] In some implementations, the position of the auxiliary turntable is adjustable.

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] refer to Figure 1 and Figure 2A sheet material 100, such as copper, aluminum, steel, or wood, needs to be cut into arc or semi-circular shapes, such as cutting a shape like cutting line 110. This solution uses a band saw 23 for cutting, transforming the straight-line band saw 23 into an arc-shaped one, or in other words, turning the straight-line band saw 23 into an arc shape, so that the direction or shape of the band saw 23 matches the cutting line 110. The band saw 23 moves to cut the sheet material 100, thereby cutting arc or semi-circular shapes, which has high work efficiency and low machine tool equipment cost.

[0041] First Embodiment

[0042] refer to Figures 3 to 8 A multi-purpose copper band saw machine tool includes a base 1 and a bed 2 that is located above the base 1 and can be raised and lowered. The bed 2 can be raised and lowered or its position adjusted by a lifting mechanism 4. The lifting mechanism 4 can be a hydraulic column or a screw nut and motor structure. Preferably, the bed 2 can be raised and lowered by two hydraulic columns.

[0043] The base 1 is equipped with a loading platform 11 for placing materials to be cut and processed, such as sheet metal 100, which can be fixed by a fixed clamp.

[0044] The bed 2 is equipped with a band saw 23 and a first saw wheel 21 that drives the band saw 23 to move. The first saw wheel 21 is connected to a corresponding motor. The bed 2 also includes a second saw wheel 22. The band saw 23 can be wound around the first saw wheel 21 and the second saw wheel 22. The first saw wheel 21 and the second saw wheel 22 are both inclined. The band saw 23 realizes the cutting motion through the first saw wheel 21 and the second saw wheel 22.

[0045] The machine tool also includes a cutting shape adjustment mechanism 5, which includes a rotatable first turntable 51. The first turntable 51 abuts against one side of the band saw 23, causing the band saw 23 to deform along the outer circumference of the first turntable 51. Alternatively, the band saw 23 can be understood as going around one side of the first turntable 51. Under the action of thrust or pressure, the band saw 23 bends and deforms, thereby switching the band saw 23 from a straight line to an arc shape, and thus cutting the plate 100 into arc or semi-circular shapes.

[0046] Therefore, according to the arc or semi-circular shape that the plate 100 needs to be cut, a first turntable 51 of matching size can be assembled. The first turntable 51 abuts against the band saw 23, causing the band saw 23 to deform against the outer circumference of the first turntable 51, thereby forming the required cutting shape. The first saw wheel 21 rotates and drives the band saw 23 to move. During the movement, the band saw 23 also drives the first turntable 51 to rotate. The first turntable 51 is set to a rotatable structure, which helps to reduce the friction between it and the band saw 23, making the movement of the band saw 23 smoother and more energy-efficient. Then, the bed 2 moves downward to cut the plate 100.

[0047] The first turntable 51 can be provided with multiple sizes, that is, multiple first turntables 51 with different diameters, so that they can be selectively assembled according to the arc or semi-circular shape that the plate 100 needs to be cut.

[0048] In addition, this machine tool can not only cut straight structures, but also cut curved structures. When the first turntable 51 is not assembled, the band saw 23 is in a straight line or shape, and can cut straight structures. When the first turntable 51 is assembled, the first turntable 51 causes the band saw 23 to be in an arc shape, and can then cut curved structures, thus achieving multi-purpose and multi-functionality.

[0049] Furthermore, the machine tool has a simple structure and relatively low manufacturing cost. It can cut a variety of materials, such as iron, steel, copper, aluminum, or wood, making it more versatile. It can cut materials such as plates and pipes.

[0050] For further explanation, please refer to Figure 6 The lower end of the band saw 23 protrudes from the bottom surface of the first turntable 51. The teeth of the band saw 23 can cut the plate 100, and the first turntable 51 will not obstruct the cutting process.

[0051] The ratio of the thickness T of the first turntable 51 to the height H of the band saw 23 is between 0.33 and 0.5. The top surface of the first turntable 51 is flush with the top surface of the band saw 23, thereby ensuring a certain cutting depth.

[0052] refer to Figure 3 and Figure 7 The cutting shape adjustment mechanism 5 also includes a first support 52 and an assembly plate 53 connected to the first support 52. The first support 52 moves up and down synchronously with the bed 2. The first support 52 can be connected to the bed 2 or to the crossbar 32 of the guide mechanism 3.

[0053] The assembly plate 53 is provided with multiple shaft holes 531, which are arranged away from the band saw 23. The first turntable 51 is assembled to the shaft holes 531 through the first rotating shaft, so that first turntables 51 of different diameters can be assembled and the position of the first turntable 51 can be adjusted to cut arc or circular structures of different sizes.

[0054] refer to Figures 3 to 5 The cutting shape adjustment mechanism 5 also includes a rotatable auxiliary turntable 54, which is located on the side of the band saw 23 away from the first turntable 51.

[0055] refer to Figure 5 Auxiliary turntables 54 are provided on both sides of the first turntable 51, such as the left and right sides.

[0056] The auxiliary turntable 54 causes the band saw 23 to fit closely against the outer circumference of the first turntable 51, improving the deformation accuracy and stability of the band saw 23, thereby improving the cutting quality.

[0057] refer to Figure 5 The auxiliary turntable 54 is position-adjustable, meaning it can be adjusted relative to the first turntable 51, for example, in the left-right direction, the length direction of the crossbar 32, or even the up-down direction. The auxiliary turntable 54 can achieve left-right position adjustment through translation mechanisms such as telescopic cylinders, lead screw nuts, and linear motors to adapt to the deformation needs of different sizes of the first turntable 51 and different band saws 23.

[0058] refer to Figure 3 and Figure 4 The machine tool also includes a guide mechanism 3, which includes a guide arm 31 and a crossbar 32. The crossbar 32 is connected to the bed 2. The guide arm 31 can be adjusted in position along the length of the crossbar 32. The crossbar 32 can be equipped with a telescopic cylinder, a lead screw nut, a linear motor, or other translational structures to achieve the position adjustment of the guide arm 31.

[0059] The lower end of the guide arm 31 is provided with a vertically arranged first guide wheel 33 and a horizontally arranged second guide wheel 34. There are two first guide wheels 33, which are located on both sides of the band saw 23 respectively, and the first guide wheels 33 are located above the band saw 23.

[0060] The auxiliary turntable 54 can be connected to the guide arm 31. The auxiliary turntable 54 can be connected to the guide arm 31 through a bracket, so that it can move with the movement of the guide arm 31. This structure is more compact, saves parts, and saves costs.

[0061] refer to Figure 6 and Figure 7 The cutting shape adjustment mechanism 5 also includes a limiting part, which includes a first limiting wheel 55 and a second limiting wheel 56. The first limiting wheel 55 and the second limiting wheel 56 are rotatably connected and can be connected to the assembly plate 53 through a support column.

[0062] The first limiting wheel 55 is located at the middle of the intersection of the band saw 23 and the first turntable 51, and is located above the band saw 23;

[0063] Two second limiting wheels 56 are provided, located at the beginning and end positions of the wrapping point between the band saw 23 and the first turntable 51, respectively, and located above the band saw 23.

[0064] The setting of the limiting part can improve the positional accuracy of the band saw 23 during the movement, making it less likely for the band saw 23 to fall off the first turntable 51 and feed downward smoothly, thereby improving the cutting quality.

[0065] The first limiting wheel 55 is a tapered shape that gradually increases in size away from the first turntable 51. The tapered first limiting wheel 55 can cause the band saw 23 to tend to move towards the first turntable 51, so that the band saw 23 can better abut against the first turntable 51, ensuring the accuracy of the band saw 23's trajectory and improving the cutting quality.

[0066] Both the first guide wheel 33 and the second guide wheel 34 can be metal rollers, as metal material helps improve wear resistance. The second guide wheel 34 can have a conical or cylindrical structure, and it can be equipped with a bearing.

[0067] Second Embodiment

[0068] refer to Figures 9 to 11 A multi-purpose copper band saw machine tool includes a base 1 and a bed 2 that is located above the base 1 and can be raised and lowered; the bed 2 can be raised and lowered or its position adjusted by a lifting mechanism 4, which can be a hydraulic column or a screw nut and motor structure, preferably, the bed 2 can be raised and lowered by a hydraulic column.

[0069] The base 1 is equipped with a loading platform 11 for placing materials to be cut and processed, such as sheet metal 100, which can be fixed by a fixed clamp.

[0070] The bed 2 is equipped with a band saw 23 and a first saw wheel 21 that drives the band saw 23 to move. The first saw wheel 21 is connected to a corresponding motor.

[0071] The machine tool also includes a cutting shape adjustment mechanism 5, which includes a rotatable first turntable 51. The first turntable 51 abuts against one side of the band saw 23, causing the band saw 23 to deform along the outer circumference of the first turntable 51. At this time, the band saw 23 is arranged around the first saw wheel 21 and the first turntable 51, thereby enabling the band saw 23 to switch from a straight line to an arc-shaped path, and thus can cut the plate 100 into arc or semi-circular shapes. In this structure, the first turntable 51 not only causes the band saw 23 to deform to form a cutting shape, but also acts as a driven wheel to drive the band saw 23 to move, and reduces the need for the second saw wheel 22.

[0072] Compared to the first embodiment, this embodiment has a simpler structure and lower manufacturing cost.

[0073] The first turntable 51 can be provided with multiple sizes, that is, multiple first turntables 51 with different diameters, so that they can be selectively assembled according to the arc or semi-circular shape that the plate 100 needs to be cut.

[0074] Because the cutting sections of a band saw have straight and curved sections, the straight sections can cut straight structures, and the curved sections can cut curved structures.

[0075] The lower end of the band saw 23 protrudes from the bottom surface of the first turntable 51. The teeth of the band saw 23 can cut the plate 100, and the first turntable 51 will not obstruct the cutting process.

[0076] The ratio of the thickness T of the first turntable 51 to the height H of the band saw 23 is between 0.33 and 0.5. The top surface of the first turntable 51 is flush with the top surface of the band saw 23, thereby ensuring a certain cutting depth.

[0077] refer to Figure 9 and Figure 10 The cutting shape adjustment mechanism 5 also includes a first bracket 52 and an assembly plate 53 connected to the first bracket 52. The first bracket 52 moves up and down synchronously with the bed 2. The first bracket 52 can be connected to the bed 2 or to another hydraulic column. The other hydraulic column moves up and down synchronously with the bed 2.

[0078] The assembly plate 53 is provided with multiple shaft holes 531, which are arranged away from the band saw 23. The first turntable 51 is assembled to the shaft holes 531 through the first rotating shaft, so that first turntables 51 of different diameters can be assembled and the position of the first turntable 51 can be adjusted to cut arc or circular structures of different sizes.

[0079] refer to Figure 10 The cutting shape adjustment mechanism 5 also includes a rotatable auxiliary turntable 54, which is located on the side of the band saw 23 away from the first turntable 51.

[0080] Auxiliary turntables 54 are provided on both sides of the first turntable 51, such as the upper and lower sides.

[0081] The auxiliary turntable 54 causes the band saw 23 to fit closely against the outer circumference of the first turntable 51, improving the deformation accuracy and stability of the band saw 23, thereby improving the cutting quality.

[0082] refer to Figure 10 The auxiliary turntable 54 is position-adjustable, meaning it can be adjusted relative to the first turntable 51, for example, in the left-right direction or even the up-down direction. The auxiliary turntable 54 can achieve left-right position adjustment through translation mechanisms such as telescopic cylinders, lead screw nuts, and linear motors to adapt to the deformation needs of different sizes of the first turntable 51 and different band saws 23.

[0083] refer to Figure 10 and Figure 11 The cutting shape adjustment mechanism 5 also includes a limiting part, which includes a first limiting wheel 55 and a second limiting wheel 56. The first limiting wheel 55 and the second limiting wheel 56 are rotatably connected and can be connected to the assembly plate 53 through a support column.

[0084] The first limiting wheel 55 is located at the middle of the intersection of the band saw 23 and the first turntable 51, and is located above the band saw 23;

[0085] The second limiting wheel 56 is located at the beginning and end of the entanglement between the band saw 23 and the first turntable 51, and is located above the band saw 23.

[0086] The setting of the limiting part can improve the positional accuracy of the band saw 23 during the movement, making it less likely for the band saw 23 to fall off the first turntable 51 and feed downward smoothly, thereby improving the cutting quality.

[0087] The first limiting wheel 55 is a tapered shape that gradually increases in size away from the first turntable 51. The tapered first limiting wheel 55 can cause the band saw 23 to tend to move towards the first turntable 51, so that the band saw 23 can better abut against the first turntable 51, ensuring the accuracy of the band saw 23's trajectory and improving the cutting quality.

[0088] Both the first guide wheel 33 and the second guide wheel 34 can be metal rollers, as metal material helps improve wear resistance. The second guide wheel 34 can have a conical or cylindrical structure, and it can be equipped with a bearing.

[0089] The above description only discloses some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the invention.
