Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe cutting machine technology, and in particular relates to a pipe cutting machine based on movable cutting tools and clamps. Background Technology
[0002] Pipe cutting machines are equipment used for cutting and processing tubular workpieces such as round and square tubes. They can efficiently and precisely cut pipes of different diameters and lengths.
[0003] For example, Chinese Patent Publication No. (CN113182705A) discloses a laser tube cutting machine, which includes a bed, a laser head, a front chuck, and a rear chuck. The front chuck of this application is fixed to one end of the bed, and then the rear chuck is slidably adjusted to move to a suitable position to support the tube. However, some tubes are usually long and need to be cut multiple times. Since a single rear chuck is used, after cutting, the rear chuck needs to be slidably adjusted to change the clamping position. Therefore, the tube needs to be unclamped first, and unclamping will affect the support of the tube. Therefore, the adjustment of the rear chuck position is inconvenient and needs to be improved. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned technical problems by providing a pipe cutting machine based on movable cutting tools and clamps, which facilitates the adjustment of the clamp position when cutting long pipes.
[0005] In view of this, the present invention provides a pipe cutting machine based on movable cutting tools and clamps, comprising:
[0006] The frame has a slidingly mounted cutting blade;
[0007] The first clamp is slidably connected to the side of the frame;
[0008] The second clamp is slidably connected to the side of the frame, and multiple clamps are provided along the sliding direction;
[0009] Multiple second clamps are used to alternately clamp the pipe fitting to adjust the distance between the first clamp and the second clamp.
[0010] Furthermore, the above technical solution also includes:
[0011] The feeding mechanism is installed on the side of the frame and has multiple components, including conveyors for pushing the pipes toward or away from the frame and for lifting or lowering them.
[0012] The length of the feeding mechanism along the sliding direction of the second clamp is greater than the length of the second clamp along its sliding direction.
[0013] In the above technical solution, the feeding mechanism further includes:
[0014] The base is mounted on the side of the rack;
[0015] The bracket includes a connecting part and a supporting part, and the supporting part is slidably connected to the base;
[0016] The support base is slidably connected to the support part;
[0017] The drive assembly includes a first drive member for driving the support portion to slide horizontally and a second drive member for driving the support seat to slide vertically.
[0018] In the above technical solution, the first driving component further includes:
[0019] Mounting plate, attached to the base;
[0020] The first drive cylinder is mounted on the mounting plate, and its output end is connected to the connecting part;
[0021] An elastic block is installed between the output end of the first drive cylinder and the connecting part.
[0022] In the above technical solution, the second driving component further includes:
[0023] The second drive cylinder is mounted on the connecting part;
[0024] There are two second drive cylinders, and their output ends are connected to the bottom surface of the support base.
[0025] Furthermore, the above technical solution also includes:
[0026] A limiting plate is installed on the base, and one side extends above the support.
[0027] The guide wheel is mounted on the side of the support and is in rolling connection with the limiting plate;
[0028] The support section is equipped with a rotating shaft connected to a guide wheel bearing.
[0029] In the above technical solution, the first fixture further includes:
[0030] The first clamping mechanism is used to clamp one end of the pipe fitting;
[0031] A drive mechanism is mounted on the first clamping mechanism and is used to drive the first clamping mechanism to rotate.
[0032] In the above technical solution, the second clamp further includes:
[0033] The support is slidably connected to the side of the frame;
[0034] The second clamping mechanism is used to clamp the surface of the pipe fitting;
[0035] The second clamping mechanism is rotatably connected to the support.
[0036] The beneficial effects of this utility model are as follows:
[0037] 1. By setting multiple second clamps, and with both the first and second clamps slidably connected to the side of the frame, the multiple second clamps alternately clamp and release the pipe fittings. While ensuring support for the pipe fittings, the distance between the first and second clamps can be changed, thereby facilitating the adjustment of the position of the second clamps, making it easier to cut the pipe fittings multiple times and improving convenience.
[0038] 2. By employing multiple feeding mechanisms, when corresponding to the second clamp, the feeding mechanism descends away from the frame to make way for the second clamp, while the remaining feeding mechanisms still support the pipe fitting, effectively improving the stability of the pipe fitting support. Before the first and second clamps fix the pipe fitting, it can prevent the pipe fitting from deforming due to sagging.
[0039] 3. By using an elastic block to connect the output end and the connecting part of the first drive cylinder, when there is a slight deviation in the horizontal conveying of multiple feeding mechanisms, that is, when they are not moving in complete synchronization, the elastic block is stretched and compressed to adapt and adjust the distance between the output end and the connecting part of the first drive cylinder, preventing jamming or damage to pipes and equipment.
[0040] 4. The limiting plate and guide wheels can improve the stability of the pipes being pushed horizontally towards the frame, avoid slight deviations in the vertical direction when the pipes are moving horizontally, and ensure high precision in pipe feeding. Attached Figure Description

[0044] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0045] Example 1:
[0046] This embodiment provides a pipe cutting machine based on movable cutter and clamp, including:
[0047] The frame 1 has a slidingly mounted cutting blade 2;
[0048] The first clamp 3 is slidably connected to the side of the frame 1;
[0049] The second clamp 4 is slidably connected to the side of the frame 1, and multiple clamps are provided along the sliding direction;
[0050] Among them, multiple second clamps 4 are used to alternately clamp the pipe fitting to adjust the distance between the first clamp 3 and the second clamp 4;
[0051] Meanwhile, the cutting tool 2 can be a laser cutting head, the specific structure of which is an existing mature technology, which is known to those skilled in the art from traditional laser cutting heads, and will not be described in detail here;
[0052] Furthermore, the sliding connections between the cutting tool 2, the first clamp 3, and the second clamp 4 and the frame 1 can all be made by using slide rails and sliders, and driven by a screw drive device, which is existing technology and will not be described in detail here.
[0053] As can be seen from this embodiment, by setting multiple second clamps 4, and both the first clamp 3 and the second clamp 4 are slidably connected to the side of the frame 1, the multiple second clamps 4 are used to alternately clamp and release the pipe fitting. While ensuring the support of the pipe fitting, the distance between the first clamp 3 and the second clamp 4 can be changed, thereby facilitating the adjustment of the position of the second clamp 4, making it easier to cut the pipe fitting multiple times and improving convenience.
[0054] Specifically, the first clamp 3 is slidably connected to the side of the frame 1, which facilitates the adjustment of the position of the first clamp 3 and improves convenience. Furthermore, after the pipe fitting has been cut once, if the second clamp 4 needs to move towards the first clamp 3, the clamp is first released through the second angle closest to the first clamp 3, while the other second clamps 4 remain clamped. The second clamp 4 closest to the first clamp 3 is then moved closer to the first clamp 3, and after moving to the appropriate position, the second clamp 4 closest to the first clamp 3 clamps the pipe fitting, while the adjacent second clamps... 4. Release the clamp on the pipe fitting and move it to a suitable position, then re-clamp it. Repeat this process. If the second clamp 4 needs to move away from the first clamp 3, first release the clamp through the second angle furthest from the first clamp 3, while the other second clamps 4 keep clamping. Move the second angle furthest from the first clamp 3 away from the first clamp 3, and after moving to a suitable position, the second clamp 4 furthest from the first clamp 3 clamps the pipe fitting. The adjacent second clamp 4 releases the clamp on the pipe fitting, moves it to a suitable position, and then re-clamps it. Repeat this process.
[0055] Furthermore, the specific number of second clamps 4 is determined according to the length of the pipe being processed. The spacing between them should be such that the pipe will not sag or bend due to its own weight after clamping. The number of second clamps 4 is determined based on this spacing and the length of the pipe.
[0056] Example 2:
[0057] This embodiment provides a pipe cutting machine based on movable cutting tools and clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features, and further includes:
[0058] The feeding mechanism 5 is installed on the side of the frame 1 and multiple of them are provided, including a conveyor for pushing the pipes toward or away from the frame 1 and for lifting or lowering them;
[0059] The length of the feeding mechanism 5 along the sliding direction of the second clamp 4 is greater than the length of the second clamp 4 along its sliding direction.
[0060] As can be seen from this embodiment, by using multiple feeding mechanisms 5, when corresponding to the second clamp 4, the feeding mechanism 5 will descend away from the frame 1 to make way for the second clamp 4, while the other feeding mechanisms 5 still support the pipe, effectively improving the stability of the pipe support. Before the first clamp 3 and the second clamp 4 fix the pipe, it can prevent the pipe from bending and deforming due to drooping.
[0061] The length of the feeding mechanism 5 along the sliding direction of the second clamp 4 should be greater than the length of the second clamp 4 along its sliding direction to ensure that the second clamp 4 is properly positioned. As the second clamp 4 slides and adjusts, the second clamp 4 can be removed sequentially. After the second clamp 4 has slid, the feeding mechanism 5 can be used again to support the pipe as needed to ensure the stability of the pipe support.
[0062] Example 3:
[0063] This embodiment provides a pipe cutting machine based on movable cutting tools and clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features: the feeding mechanism 5 includes:
[0064] Base 50 is mounted on the side of rack 1;
[0065] The bracket 51 includes a connecting part 510 and a supporting part 511, and the supporting part 511 is slidably connected to the base 50;
[0066] Support base 52 is slidably connected to support part 511;
[0067] The drive assembly includes a first drive member 53 for driving the support portion 511 to slide horizontally and a second drive member for driving the support base 52 to slide vertically.
[0068] Meanwhile, the support part 511 and the base 50, as well as the support base 52 and the support part 511, are slidably connected by slide rails and sliders.
[0069] As can be seen from this embodiment, the sliding connection between the support part 511 and the base 50 and the driving of the first driving member 53 facilitate the horizontal pushing of the pipe and the movement of it towards the side of the frame 1. The sliding connection between the support base 52 and the support part 511 and the driving of the second driving member facilitate the vertical lifting of the pipe and the adjustment of the alignment between the pipe and the first clamp 3 and the second clamp 4. It also facilitates the removal of the support base 52 to make way for the second clamp 4.
[0070] Example 4:
[0071] This embodiment provides a pipe cutting machine based on movable cutting tools and clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features: the first driving component 53 includes:
[0072] Mounting plate 530 is connected to base 50;
[0073] The first drive cylinder 531 is mounted on the mounting plate 530, and its output end is connected to the connecting part 510.
[0074] The elastic block 532 is installed between the output end of the first drive cylinder 531 and the connecting part 510;
[0075] The elastic block 532 can be made of rubber and is fixed to the output end of the first drive cylinder 531 and the connecting part 510 by bolts. For example, a stepped hole is opened on the elastic block 532, and then the bolt passes through the stepped hole to connect to the output end of the first drive cylinder 531 or the connecting part 510. The first drive cylinder 531 can be a cylinder or a hydraulic cylinder.
[0076] As can be seen from this embodiment, by using an elastic block 532 to connect the output end of the first drive cylinder 531 and the connecting part 510, when there is a slight deviation in the horizontal conveying of multiple feeding mechanisms 5, that is, when they are not moving in complete synchronization, the elastic block 532 is stretched and compressed to adapt and adjust the distance between the output end of the first drive cylinder 531 and the connecting part 510, so as to prevent jamming or damage to pipes and equipment.
[0077] Example 5:
[0078] This embodiment provides a pipe cutting machine based on a movable tool and clamp. In addition to the technical solutions of the above embodiments, it also has the following technical features: the second driving component includes:
[0079] The second drive cylinder 54 is mounted on the connecting part 510;
[0080] There are two second drive cylinders 54, and their output ends are connected to the bottom surface of the support base 52.
[0081] Meanwhile, the second drive cylinder 54 can be a pneumatic cylinder or a hydraulic cylinder, and the two second drive cylinders 54 are synchronously controlled, which is an existing mature technology and will not be elaborated here.
[0082] As can be seen from this embodiment, by setting two second drive cylinders 54, it is easy to ensure the horizontal lifting of the support base 52, improve stability, and ensure the support effect on the pipe fitting.
[0083] Example 6:
[0084] This embodiment provides a pipe cutting machine based on movable cutting tools and clamps. In addition to the technical solutions of the above embodiments, it also has the following technical features, and further includes:
[0085] Limiting plate 55 is installed on base 50 and extends on one side above support 511;
[0086] The guide wheel 56 is installed on the side of the support 511 and is rotatably connected to the limiting plate 55;
[0087] The support part 511 is provided with a rotating shaft that is connected to the guide wheel 56 bearing.
[0088] As can be seen from this embodiment, the limiting plate 55 and the guide wheel 56 can improve the stability of the pipe being pushed horizontally towards the frame 1, avoid the pipe from having a slight deviation in the vertical direction when moving horizontally, and ensure the high precision of the pipe feeding.
[0089] Example 7:
[0090] This embodiment provides a pipe cutting machine based on a movable tool and clamp. In addition to the technical solutions of the above embodiments, it also has the following technical features: the first clamp 3 includes:
[0091] The first clamping mechanism 30 is used to clamp one end of the pipe fitting;
[0092] The drive mechanism 31 is mounted on the first clamping mechanism 30 and is used to drive the first clamping mechanism 30 to rotate.
[0093] Meanwhile, the first clamping mechanism 30 can be a chuck, and the driving mechanism 31 can be a motor. That is, the first clamp 3 can be a rotary chuck. Its specific structure is existing technology and will not be described in detail here.
[0094] As can be seen from this embodiment, the rotation facilitates circumferential cutting of multiple pipes by the cutting tool 2, ensuring high cutting efficiency. Furthermore, the drive mechanism 31 resets after driving the first clamping mechanism 30 to rotate one revolution, thus avoiding tangling of the air pipes and wires on the first clamp 3 and the second clamp 4.
[0095] Example 8:
[0096] This embodiment provides a pipe cutting machine based on a movable tool and clamp. In addition to the technical solutions of the above embodiments, it also has the following technical features: the second clamp 4 includes:
[0097] Support 40 is slidably connected to the side of frame 1;
[0098] The second clamping mechanism 41 is used to clamp the surface of the pipe fitting;
[0099] The second clamping mechanism 41 is rotatably connected to the support 40;
[0100] Meanwhile, the second clamping mechanism 41 can use multiple cylinders. Specifically, it may include a turntable and four cylinders evenly spaced on the turntable. The turntable and the support 40 are connected by bearings. Its specific structure is a mature existing technology, which can be learned by those skilled in the art from traditional fixtures, and will not be described in detail here.
[0101] As can be seen from this embodiment, by using a rotatable connection between the second clamping mechanism 41 and the support 40, it is easy for the second clamp 4 to clamp the pipe and then rotate with the first clamp 3, which facilitates cutting. Furthermore, the use of a bearing connection can improve the stability of rotation.
