Description

Technical Field

[0001] The utility model relates to the technical field of circular sawing machines, in particular to a circular sawing machine for cutting steel plates. Background Art

[0002] The circular sawing machine for cutting steel plates is one of the commonly used cutting equipment in the metal processing industry, mainly used for precisely cutting metal plates such as steel, stainless steel, and aluminum. While the circular saw blade rotates at high speed, it cuts the metal plate along the set cutting line to achieve the processing and manufacturing of metal materials. Circular sawing machines usually feature high cutting speed, precision, and stability, and are suitable for cutting and processing metal plates of various specifications and materials.

[0003] The circular sawing machine for cutting steel plates indeed has some limitations in traditional applications. For example, when dealing with large-sized plates, the overly large plates will limit the moving range of the sawing machine, and workers need to manually adjust the position of the plates to meet the cutting requirements. This not only reduces work efficiency but also affects cutting precision and increases the number of processes. Such manual adjustment is prone to introducing deviations, thus affecting cutting quality, and at the same time increasing the complexity and time cost of the production process.

[0004] Based on this, those skilled in the art have proposed a circular sawing machine for cutting steel plates. Content of the Utility Model

[0005] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide a circular sawing machine for cutting steel plates.

[0006] The technical solution of the present utility model is as follows: A circular sawing machine for cutting steel plates includes a placing mechanism, and further includes:

[0007] A driving mechanism, which is arranged below the placing mechanism and is used to drive the placing mechanism or the cutting end to rotate to achieve the purpose of circular cutting;

[0008] An adjusting mechanism, which is arranged above the placing mechanism and is used to adjust the position of the cutting end, thereby achieving the cutting of circular plates with different diameters.

[0009] By the above technical means, the placing mechanism is used to place the plate, the adjusting mechanism is used to control the cutting height and cutting diameter of the plate, and the driving mechanism can control the placing mechanism and the adjusting mechanism to rotate separately or simultaneously. In this way, when cutting different plates, they can cooperate to achieve fine cutting and flexible adjustment according to the different shapes and sizes of the plates.

[0010] As a preferred embodiment, the placement mechanism includes a rotating disk and a placement rack. The placement rack is connected to the rotating disk by screws. Vertical plates are welded equidistantly on the top of the placement rack, and a fixed column is arranged below the rotating disk.

[0011] By the above technical means, the advantage of connecting by screws is that the placement rack can be conveniently separated from the rotating disk, so that the placement rack can be replaced when it has been used for a period of time.

[0012] As a preferred embodiment, the driving mechanism includes a rotating plate, an inclined tooth ring, a first driving motor and an inclined gear. The rotating plate is rotatably connected to the outside of the fixed column. The inclined tooth ring is fixedly connected to the outside of the fixed column. The first driving motor is fixedly connected to the rotating plate. The inclined gear is fixedly connected to one side of the output end of the first driving motor, and the inclined gear is meshed with the inclined tooth ring.

[0013] By the above technical means, the rotation of the first driving motor can drive the inclined gear to rotate, and then drive the rotating plate to rotate through the meshing of the inclined gear and the inclined tooth ring.

[0014] As a preferred embodiment, a reinforcing plate is fixedly connected to the rotating plate and located outside the output end of the first driving motor. The reinforcing plate is rotatably connected to the output end of the first driving motor.

[0015] By the above technical means, through such a setting, the strength during the rotation of the output end of the first driving motor can be enhanced.

[0016] As a preferred embodiment, the adjusting mechanism includes a sleeve, a lifting screw rod, a cross frame and a positioning nut. The sleeve is fixedly connected to the rotating plate. The lifting screw rod is arranged inside the sleeve and its top extends above the sleeve. The cross frame is fixedly connected to the top of the lifting screw rod. The positioning nut is rotatably connected to the top of the sleeve and located outside the lifting screw rod, and the positioning nut is threadedly connected to the lifting screw rod.

[0017] By the above technical means, rotating the positioning nut can drive the lifting screw rod to move up and down, and then the height of the cross frame can be controlled, so as to facilitate the operation according to plates of different thicknesses. In addition, the rotation of the rotating plate can drive the sleeve to rotate, and then drive the cross frame to rotate.

[0018] As a preferred embodiment, the adjusting mechanism further includes an adjusting screw rod and an adjusting block. Two square strip grooves are symmetrically formed inside the cross frame. Sliding blocks are slidably connected inside the square strip grooves. The adjusting screw rod is rotatably connected to one side of one of the sliding blocks, and a matching optical rod is fixedly connected to one side of the other sliding block. The adjusting screw rod and the optical rod both extend to the outside of the cross frame. The adjusting screw rod is threadedly connected to the cross frame, and the optical rod is slidably connected to the cross frame. The adjusting block is arranged outside the adjusting screw rod and the optical rod. The adjusting screw rod is rotatably connected to the adjusting block, and the optical rod is fixedly connected to the adjusting block.

[0019] By the above technical means, by rotating the adjusting screw rod, the adjusting screw rod moves relative to the cross frame, thereby controlling the movement of the adjusting block, and thus the distance between the adjusting block and the cross frame can be controlled.

[0020] As a preferred embodiment, a center cone is threadedly connected to the cross frame, and a connecting head is fixedly connected to the adjusting block.

[0021] By the above technical means, the center cone is used to contact the plate, and the contact point is the center position of the plate to be cut. A plasma cutting tool head is provided at the bottom of the connecting head, and the connecting head is connected to external plasma power supply and gas supply equipment.

[0022] As a preferred embodiment, the driving mechanism further includes a second driving motor. The second driving motor is installed inside the fixed column, and its output end extends above the fixed column and is fixedly connected to the bottom of the rotating disk. The bottom of the fixed column is fixedly connected to a bottom plate.

[0023] By the above technical means, when the second driving motor rotates, it can drive the rotating disk to rotate. Cooperating with the first driving motor, the device can achieve different rotating effects and meet different cutting requirements.

[0024] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0025] 1. Through the combined use of the first driving motor and the second driving motor, the cross frame and the rotating disk can rotate independently. The cooperation of the two can achieve different rotating effects. Thus, when processing some large plates, the two can cut the plate by rotating in opposite directions, avoiding the drawback that the traditional unidirectional rotating sawing machine needs to adjust the position of the plate, resulting in a reduction in the cutting accuracy of the plate.

[0026] 2. Drive the lifting screw rod to move by rotating the positioning nut, so that the lifting screw rod drives the cross frame to move, so that it can be adjusted according to different plate thicknesses. Then rotate the adjusting screw rod to drive the adjusting block to move by using the adjusting screw rod, so that the diameter of the cutting circular plate can be controlled, so that the device can be used for plates with different thicknesses and diameters.

[0035] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments

[0036] Embodiment

[0037] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present utility model provides a circular sawing machine for steel plate cutting: including a placing mechanism, and further including:

[0038] The driving mechanism is arranged below the placing mechanism. The driving mechanism is used to drive the placing mechanism or the cutting end to rotate, so as to achieve the purpose of circular cutting.

[0039] The adjusting mechanism is arranged above the placing mechanism. The adjusting mechanism is used to adjust the position of the cutting end, so as to cut circular plates with different diameters.

[0040] To sum up: The placing mechanism is used to place the plate, the adjusting mechanism is used to control the cutting height and cutting diameter of the plate, and the driving mechanism can control the placing mechanism and the adjusting mechanism to rotate separately or simultaneously. In this way, when cutting different plates, they can cooperate to achieve fine cutting and flexible adjustment according to the shape and size of the plates.

[0041] Such as Figure 1 and Figure 2 As shown, the placing mechanism includes a rotating disk 1 and a placing rack 2. The placing rack 2 is connected to the rotating disk 1 by screws 3. Vertical plates are welded equidistantly at the top of the placing rack 2, and a fixing column 4 is arranged below the rotating disk 1.

[0042] To sum up: The advantage of connecting by screws 3 is that the placing rack 2 can be easily separated from the rotating disk 1. In this way, when the placing rack 2 is used for a period of time, it can be replaced.

[0043] Such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the driving mechanism includes a rotating plate 5, an inclined tooth ring 6, a first driving motor 7 and an inclined gear 8. The rotating plate 5 is rotatably connected to the outside of the fixing column 4. The inclined tooth ring 6 is fixedly connected to the outside of the fixing column 4. The first driving motor 7 is fixedly connected to the rotating plate 5. The inclined gear 8 is fixedly connected to one side of the output end of the first driving motor 7.

[0044] To sum up: The rotation of the first driving motor 7 can drive the inclined gear 8 to rotate, and then drive the rotating plate 5 to rotate through the meshing of the inclined gear 8 and the inclined tooth ring 6.

[0046] To sum up: Through such a setting, the strength of the output end of the first driving motor 7 during rotation can be enhanced.

[0047] Such asFigure 5 and Figure 6 As shown in Figure 6 , the adjusting mechanism includes a sleeve 10, a lifting screw rod 11, a cross frame 12, and a positioning nut 13. The sleeve 10 is fixedly connected to the rotating plate 5. The lifting screw rod 11 is arranged inside the sleeve 10 and its top extends above the sleeve 10. The cross frame 12 is fixedly connected to the top of the lifting screw rod 11. The positioning nut 13 is rotatably connected to the top of the sleeve 10 and is located outside the lifting screw rod 11. The positioning nut 13 is threadedly connected to the lifting screw rod 11;

[0048] In summary: By rotating the positioning nut 13, the lifting screw rod 11 can be driven to move up and down, and then the height of the cross frame 12 can be controlled, so as to facilitate the operation according to plates of different thicknesses. In addition, by rotating the rotating plate 5, the sleeve 10 can be driven to rotate, and then the cross frame 12 can be driven to rotate.

[0049] It should be particularly noted that in order to ensure the positioning effect on the lifting screw rod 11, positioning screws can be arranged on the outside of the positioning nut 13. This kind of positioning nut 13 is an existing mature technology. Therefore, it will not be elaborated too much in this embodiment.

[0050] As Figure 5 and Figure 6 shown, the adjusting mechanism further includes an adjusting screw rod 14 and an adjusting block 17. Two square strip grooves are symmetrically opened inside the cross frame 12. Sliding blocks 15 are slidably connected inside the square strip grooves. The adjusting screw rod 14 is rotatably connected to one side of one of the sliding blocks 15. A smooth rod for cooperation is fixedly connected to one side of the other sliding block 15. The adjusting screw rod 14 and the smooth rod both extend outside the cross frame 12. The adjusting screw rod 14 is threadedly connected to the cross frame 12. The smooth rod is slidably connected to the cross frame 12. The adjusting block 17 is arranged outside the adjusting screw rod 14 and the smooth rod. The adjusting screw rod 14 is rotatably connected to the adjusting block 17. The smooth rod is fixedly connected to the adjusting block 17;

[0051] In summary: By rotating the adjusting screw rod 14, the adjusting screw rod 14 moves relative to the cross frame 12, and then the movement of the adjusting block 17 is controlled, so that the distance between the adjusting block 17 and the cross frame 12 can be controlled.

The second driving motor 19 is installed inside the fixed column 4, and its output end extends above the fixed column 4 and is fixedly connected to the bottom of the rotating disk 1. The bottom of the fixed column 4 is fixedly connected to a bottom plate 20;

[0055] In summary: When the second driving motor 19 rotates, it can drive the rotating disk 1 to rotate. Cooperating with the first driving motor 7, the device can achieve different rotation effects and meet different cutting requirements.

[0056] Working principle:

[0057] By the rotation of the first driving motor 7, the bevel gear 8 meshes with the bevel gear ring 6, thereby driving the rotating plate 5 to rotate, so that the rotating plate 5 can rotate around the placement rack 2. On the other hand, by the rotation of the second driving motor 19, the rotating disk 1 can be driven to rotate, so that the rotating disk 1 can drive the placement rack 2 to rotate. The two cooperate to achieve different rotation effects and meet different cutting requirements;

[0058] By rotating the positioning nut 13, the lifting screw rod 11 can be driven to move, and then the lifting screw rod 11 drives the cross frame 12 to move, so that it can be adjusted according to different plate thicknesses. After the adjustment is completed, rotate the center cone 16 so that the center cone 16 contacts the center of the plate to achieve the positioning of the plate. Then rotate the adjustment screw rod 14, and use the adjustment screw rod 14 to drive the adjustment block 17 to move, so that the diameter of the cutting circular plate can be controlled.

[0059] Finally, it should be noted that: The above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
