[0001] The utility model relates to the technical field of metal can body processing, in particular to a firmly clamped circular cutting machine. Background Art

[0002] Metal cans are a common packaging container, widely used in food, beverage, cosmetics and other industries. Metal can processing refers to a series of processes to form a can with the required shape and size. The circular cutting machine can cut the material into a circular shape. It is widely used in metal and non-metal industries. It has the characteristics of safety, reliability, reasonable structure and high working efficiency. It is a machine often used in metal can processing.

[0003] The patent document with application number CN90205360.4 discloses a manual circular cutting machine, which includes a magnet, a lower spindle, an upper spindle, a cutter disc and a hand wheel mounted on the upper spindle. The cutter head is mounted on the cutter disc through a cutter head frame and a cutter rod. The manual hand wheel can make the cutter head move in a circle with the lower spindle as the axis and cut the iron plate. The size of the circular iron plate to be cut can be changed by changing the position of the cutter head frame, and the feed amount of the cutter head can be changed by adjusting the nut. The utility model has a simple structure, is easy to carry and operate, does not require power or air source, and can avoid secondary processing. It is particularly suitable for manual cutting of circular iron plates with a thickness of 0.5-5mm and a diameter of 200-600mm.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0021] The utility model discloses a firmly clamped circular cutting machine which is mainly used in the scene where the limiting of the material is not firmly enough.

[0022] Reference Figure 1-Figure 2 A firmly clamped circular cutting machine comprises: a base 1, a support platform 2 is fixedly connected to the right side of the top of the base 1, a first limiting groove 3 is opened on the left side of the support platform 2, the first limiting groove 3 is rotatably connected to the inner walls at the upper and lower ends of the first limiting groove 3, a first rotating wheel 5 is fixedly connected to the side of the first limiting groove 3 extending from the first limiting groove 3, a support arm 6 is threadedly connected to the surface of the first limiting groove 4, a rotating motor 7 is fixedly connected to the left side of the top of the support arm 6, a rotating arm 8 is fixedly connected to the output end of the rotating motor 7, and a center rod 9 is fixedly connected to the right side of the bottom end of the rotating arm 8, a second limiting groove 19 is opened in the middle of the top of the base 1, a bidirectional threaded rod 20 is rotatably connected to the inner walls on the left and right sides of the second limiting groove 19, and a second rotating wheel 21 is fixedly connected to one end of the bidirectional threaded rod 20 extending from the second limiting groove 19, two clamping plates 22 are threadedly connected to the surface of the bidirectional threaded rod 20, and anti-slip patches 23 are fixedly connected to the opposite sides of the two clamping plates 22.

[0023] In this embodiment: the support table 2 can provide support for the support arm 6, and the support arm 6 can provide support for the rotating arm 8. The material is placed on the top of the base 1, and the bidirectional threaded rod 20 can be driven to rotate by rotating the second rotating wheel 21. The rotation of the bidirectional threaded rod 20 can drive the clamping plate 22 on its surface to move. The second limiting groove 19 can limit the movement of the clamping plate 22 so that the clamping plate 22 moves toward each other along the bidirectional threaded rod 20, thereby clamping the material to prevent the material from shifting during the processing and ensure the accuracy of material processing. The anti-slip patch 23 can increase the friction between the clamping plate 22 and the material to ensure the stability of the clamping, and the material is rotated after being clamped. The first rotating wheel 5 can drive the first screw 4 to rotate, and the rotation of the first screw 4 can drive the support arm 6 on its surface to move. The movement of the support arm 6 can be limited by the first limiting groove 3 so that the support arm 6 can move up and down along the first screw 4. The movement of the support arm 6 can drive the rotating arm 8 to move up and down until the center rod 9 contacts the surface of the material, so that the distance between the rotating arm 8 and the material can be adjusted. The center rod 9 can not only determine the position of the center of the material, but also further limit the material. After the adjustment is completed, the rotating motor 7 is started, and the rotating motor 7 can drive the rotating arm 8 to rotate, thereby realizing the circle cutting operation of the material.

[0024] In the above scheme, it is considered that the circle cutting machine cuts circles of different sizes according to different needs of the situation. The specific operation is as follows:

[0025] Reference Figure 2-Figure 3 In a preferred embodiment, the bottom end of the rotating arm 8 is located on the left side of the center rod 9 and is fixedly connected to two support plates 10, the opposite sides of the two support plates 10 are rotatably connected to a third lead screw 11, one side of the third lead screw 11 extending out of the support plate 10 is fixedly connected to a third rotating wheel 12, the opposite sides of the two support plates 10 are located at the rear end of the third lead screw 11 and are fixedly connected to a limiting rod 13, the surface of the third lead screw 11 is threadedly connected to a connecting seat 14, the bottom end of the connecting seat 14 is fixedly connected to a cutting tool 15, and the bottom surface of the cutting tool 15 is flush with the bottom surface of the center rod 9;

[0026] In this embodiment: the support plate 10 can provide support for the third lead screw 11 and the limit rod 13, the third lead screw 11 can be driven to rotate by rotating the third rotating wheel 12, the rotation of the third lead screw 11 can drive the connecting seat 14 on its surface to move, and the movement of the connecting seat 14 can be limited by the limit rod 13 so that the connecting seat 14 can move left and right along the third lead screw 11, so that the cutting radius can be adjusted, expanding the application range of the circular cutting machine, and the bottom surface of the cutting tool 15 is flush with the bottom surface of the center rod 9 to facilitate cutting of the material.

[0027] In the above solution, considering the need to accurately adjust the position of the cutting tool 15, the specific operations are as follows:

[0028] Reference Figure 2-Figure 3 In a preferred embodiment, a scale 16 is fixedly connected to the front and rear ends of the support plate 10 near the limiting rod 13, and a pointer 17 is fixedly connected to the middle of the front and rear ends of the connecting seat 14;

[0029] In this embodiment, the position of the cutting tool 15 can be accurately adjusted by the scale 16, thereby effectively improving the processing accuracy, and the data on the scale 16 can be easily observed by the pointer 17.

[0030] In the above scheme, considering that a lot of dust will be generated during the cutting process, the circular cutting machine is prone to tipping over due to external force collision when placed. The specific operation is as follows:

[0031] Reference Figure 1-Figure 2 In a preferred embodiment, a dust collecting chamber is provided inside the rotating arm 8, a dust collecting head 18 is fixedly connected to the front end of the rotating arm 8, the dust collecting head 18 is trapezoidal, the dust collecting head 18 is connected to the dust collecting chamber through a pipeline, and an anti-slip pad 24 is fixedly connected to the bottom end of the base 1;

[0032] In this embodiment: the dust generated during the cutting process can be sucked up by the dust suction head 18 and transported to the dust collecting chamber arranged inside the rotating arm 8 for storage. The anti-slip pad 24 can increase the friction between the circular cutter and the contact surface, thereby effectively improving the stability of the circular cutter when placed.

[0033] Working principle: when in use, first put the material on the top of the base 1, rotate the second rotating wheel 21 to make the bidirectional threaded rod 20 rotate, and then drive the clamping plate 22 to move. Due to the limitation of the second limiting groove 19, the clamping plate 22 moves toward each other along the bidirectional threaded rod 20, thereby clamping the material to prevent the material from shifting during the processing and ensuring the accuracy of material processing. At this time, the anti-slip patch 23 can increase the friction between the clamping plate 22 and the material, ensuring the stability of the clamping. After the material is clamped, rotate the first rotating wheel 5 to make the first screw 4 rotate, and then drive the support arm 6 to move. Due to the limitation of the first limiting groove 3, the support arm 6 moves up and down along the first screw 4, and then drives the rotating arm 8 to move up and down until the center rod 9 contacts the surface of the material. At this time, the center rod 9 can not only determine the position of the center of the material, but also can further limit the material. After the adjustment is completed, start the rotating motor 7, which will drive the rotating arm 8 to rotate and perform a circle cutting operation on the material.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
