Description

Technical Field

[0001] This utility model relates to the field of circular cutting machine technology, specifically a circular cutting machine for processing metal tubes to prevent deformation. Background Technology

[0002] In the field of metal tube processing, traditional circular cutting machines have many problems. With the continuous improvement of the precision requirements of modern industry for metal tube processing, the deformation of metal tubes during the cutting process has become a key problem that urgently needs to be solved.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Metal Tube Processing Circular Cutting Machine to Avoid Deformation," with publication (announcement) number "CN220943408U." This patent mainly involves a sliding table mounted on a base, a vertical plate slidably mounted on the sliding table, a first motor fixedly mounted on the vertical plate, and a cutting blade mounted on the output shaft of the first motor. A first mounting plate is fixedly mounted on one end of the base, and a second mounting plate is mounted on the other end. A second motor is fixedly mounted on the outer side of the first mounting plate, and the output shaft of the second motor is fixedly mounted in the inner ring of a bearing on the first mounting plate. A rotating rod is fixedly mounted in the inner ring of the bearing on the second mounting plate. The output shaft of the second motor and the rotating rod are respectively mounted on... There are locking components for fixing the metal tube; the base is also equipped with support components for supporting the metal tube, which facilitates the clamping and fixing of metal tubes of different diameters, allowing the metal tube to be cut in a circumferential manner and avoiding deformation. However, this device has shortcomings in the treatment of the inner side of the processed tube. When subjected to processing force, if the inner side lacks support, the internal stress distribution is extremely uneven. Especially when performing high-precision cutting operations, the external force applied by the cutting tool can easily cause irregular deformation inside the processed tube. At the same time, the cutting process generates a large amount of waste material and coolant, resulting in a great waste of resources. Therefore, we propose a metal tube processing circular cutting machine to prevent metal tube deformation. Utility Model Content

The rotating shaft passes through the first mounting plate and the second mounting plate via bearings. One end of each locking block is connected to one end of the rotating shaft. The first motor is... On the side of the second mounting plate away from the workbench, and with the drive end connected to one end of the rotating shaft, the other end of each locking block is provided with an anti-deformation component. The anti-deformation component includes a telescopic shaft, a mounting circular plate, an electric telescopic rod, and a movable block. One end of the telescopic shaft is connected to the locking block, and the other end is connected to the mounting circular plate. The electric telescopic rod is located on the side of the mounting circular plate, and one end is connected to the movable block. The workbench is located below the center of the positioning mechanism and has a waste discharge trough. A collection box is placed below the waste discharge trough.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model utilizes the telescopic shaft, mounting circular plate, electric telescopic rod, and movable block in the anti-deformation component to play a key role. The three sets of electric telescopic rods are equidistantly arranged and can adjust the position of the movable block according to the inner diameter of the processing tube, so that its side is in close contact with the inner side of the processing tube, providing uniform support force from the inside, effectively preventing the processing tube from deforming due to uneven force during the cutting process.

The double fixing method of inside and outside not only ensures the accuracy of the position of the processing tube during cutting, but also greatly reduces the risk of deformation, thereby improving the quality and precision of the processing tube.

[0014] 2. This utility model uses a filter plate inside the collection box to filter waste materials and separate the coolant. The liquid flows into a storage tank through an outlet pipe, and the liquid in the storage tank can then be sprayed out through a cooling nozzle via a water supply pipe, realizing the recycling of coolant. This recycling mechanism greatly reduces coolant consumption and lowers processing costs. At the same time, the collection box's collection and preliminary filtration of waste materials not only prevents waste materials from scattering and polluting the working environment, but also facilitates the subsequent recycling and processing of valuable parts such as metal scraps in the waste materials. The entire process achieves an organic combination of efficient resource utilization and environmental protection, improving the sustainability of production. In the long-term processing of pipe manufacturing, it helps enterprises save resource costs and reduce waste emissions.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 -Appendix Figure 6This utility model discloses a metal tube processing circular cutting machine to prevent deformation of metal tubes. The cutting mechanism 2 is located at the rear end of the top surface of the worktable 1, and the positioning mechanism 3 is located at the front end of the top surface of the worktable 1. The positioning mechanism 3 includes a first mounting plate 301, a second mounting plate 302, a rotating shaft 303, a locking block 304, and a first motor 305. The first mounting plate 301 and the second mounting plate 302 are respectively located at the left and right ends of the top surface of the worktable 1, providing a solid basic framework for the entire positioning system. The rotating shaft 303 passes through the first mounting plate 301 and the second mounting plate 302 through bearings, thereby ensuring its smooth and stable rotation. One end of each locking block 304 is connected to one end of the rotating shaft 303. The first motor 305 is located on the side of the second mounting plate 302 away from the worktable 1, and its driving end is connected to one end of the rotating shaft 303. When the first motor 305 starts running, it can drive the rotating shaft. The 303 and the snap-fit ​​block 304 enable flexible rotation operation. The other end of the snap-fit ​​block 304 is equipped with an anti-deformation component 4. The anti-deformation component 4 includes a telescopic shaft 401, a mounting circular plate 402, an electric telescopic rod 403, and a movable block 404. One end of the telescopic shaft 401 is connected to the snap-fit ​​block 304, and the other end is connected to the mounting circular plate 402. The electric telescopic rod 403 is located on the side of the mounting circular plate 402, and one end is connected to the movable block 404. The worktable 1 is located below the center of the positioning mechanism 3 and has a waste discharge trough 5. A collection box 6 is placed below the waste discharge trough 5. A water storage tank 7 is connected to one side of the collection box 6. The water storage tank 7 is connected to a cooling nozzle 8 through a water supply pipe 701. When the processing pipe 9 is processing, the cooling nozzle 8 can spray coolant in a timely manner to cool the processing pipe 9. At the same time, the waste generated during processing can fall into the collection box 6 through the waste discharge trough 5.

[0026] In the first embodiment, a processing tube 9 is installed between the first mounting plate 301 and the second mounting plate 302. The snap-fit ​​block 304 is conical, with the end of the cone with the smaller diameter facing the processing tube 9. The inner side of the processing tube 9 is in close contact with the side of the movable block 404. The movable block 404 is fan-shaped and circular. There are three sets of electric telescopic rods 403, and the three sets of electric telescopic rods 403 are equidistantly arranged on the side of the mounting circular plate 402. The collection box 6 is equipped with a filter plate 601. The cooling nozzle 8 is semi-circular and is located near the processing tube 9. The front end of the top of the workbench 1 is equipped with a support frame 10, and the rear end of the support frame 10 is fixedly connected to one side of the cooling nozzle 8.

[0027] Specifically, the position of the movable block 404 can be precisely adjusted by the flexible extension and retraction of the electric telescopic rod 403 to adapt to the processing requirements of different specifications of processing tubes 9, providing strong internal support to prevent deformation of the processing tubes 9. The filter plate 601 inside the collection box 6 can effectively filter and separate the waste generated during the processing. The separated coolant flows into the water storage tank 7 through the water outlet pipe. The liquid in the water storage tank 7 can be sprayed out by the cooling nozzle 8 through the water supply pipe 701 to realize the recycling of coolant.

[0028] In embodiment 2, two mounting brackets 11 are symmetrically installed on the snap-fit ​​block 304. The mounting bracket 11 is threaded with a first handle bolt 12. One end of the first handle bolt 12 is rotatably connected to an arc plate 13. The inner side of the arc plate 13 is in close contact with the outer side of the processing tube 9. The cutting mechanism 2 includes a slide table, a vertical plate, a second motor, and a cutting blade. The top surface of the slide table is slidably connected to the bottom end of the vertical plate. The second motor is located on one side of the vertical plate, and its output shaft is connected to the center of the cutting blade. A sliding groove is opened at the upper part of one end of the worktable 1. A slider is slidably installed inside the sliding groove. The bottom of the first mounting plate 301 is fixedly connected to the upper end of the slider. A second handle bolt is threadedly connected to one end of the worktable 1. One end of the second handle bolt extends into the inside of the sliding groove and is rotatably connected to one side of the slider.

[0029] Specifically, when the first handle bolt 12 is rotated, the arc plate 13 will produce corresponding displacement and angle changes, which can accurately adjust the clamping force of the arc plate 13 on the processing tube 9, providing a stable and reliable fixing force from the outside of the processing tube 9. In cooperation with the internal anti-deformation component 4, when the second handle bolt is rotated, the slider will slide smoothly in the groove under its push or traction, thereby driving the first mounting plate 301 to achieve fine adjustment of its position. This not only facilitates the precise adjustment of the position of the first mounting plate 301 according to the length of the processing tube 9 or processing requirements, but also enables the first mounting plate 301 to be firmly locked in the required position after adjustment.

[0030] Working principle:

[0031] When preparing to process the processing tube 9, first place the processing tube 9 between the first mounting plate 301 and the second mounting plate 302. The snap-fit ​​block 304, driven by the first motor 305, can rotate around the rotating shaft 303. Its conical structure facilitates insertion into one end of the processing tube 9. Subsequently, by adjusting the anti-deformation component 4 on the snap-fit ​​block 304, the three sets of electric telescopic rods 403 extend and retract at equal intervals according to the inner diameter of the processing tube 9, driving the movable block 404 to move on the mounting circular plate 402, so that the side of the movable block 404 is in close contact with the inner side of the processing tube 9, providing internal support. The uniform support force initially prevents deformation of the processed tube 9. At the same time, the first handle bolt 12 on the rotating mounting bracket 11 drives the arc plate 13 to rotate, so that its inner side fits tightly with the outer side of the processed tube 9, clamping the processed tube 9 from the outside. The dual fixing methods inside and outside work together to ensure that the processed tube 9 is accurately positioned during the cutting process and the risk of deformation is greatly reduced. During cutting, the second motor of the cutting mechanism 2 drives the cutting blade to rotate. The sliding connection between the slide table and the vertical plate can adjust the cutting position to cut the processed tube 9, ensuring processing quality and precision.

[0032] During the cutting process of the processing tube 9, the waste material and coolant mixture generated falls into the collection box 6 through the waste discharge trough 5 below the center of the positioning mechanism 3 of the worktable 1. The filter plate 601 in the collection box 6 plays a key role in separating the waste material from the coolant. The separated coolant flows into the water storage tank 7 through the water outlet pipe. When cooling is required, the coolant in the water storage tank 7 reaches the semi-circular cooling nozzle 8 under pressure through the water supply pipe 701 and is sprayed out from the nozzle near the side of the processing tube 9 to cool and lower the temperature of the cutting processing tube 9, preventing it from deforming or damaging the tool due to high temperature. The sprayed coolant mixes with the waste material again and flows into the collection box 6, repeating the above filtration and recycling process to realize the recycling of coolant. After preliminary filtration, the waste material collected in the collection box 6 is convenient for subsequent recycling and processing of valuable parts such as metal scraps.
