Description

Technical Field

[0001] This utility model relates to the technical field of circumferential tube cutting devices, and in particular to a magnesium oxide circumferential tube cutting device. Background Technology

[0002] As various industries increasingly demand higher performance from magnesium oxide tubes and their applications expand, more stringent requirements are being placed on the processing precision and quality of these tubes. Among these requirements, circumferential cutting is a crucial step in the production process. The quality of the circumferential cutting directly affects the dimensional accuracy, end-face flatness, and subsequent assembly and performance of the magnesium oxide tube.

[0003] Currently, among existing pipe circumferential cutting equipment, such as the patent with announcement number CN206999032U, a utility model provides a high-efficiency hose circumferential cutting machine and a high-efficiency hose circumferential cutting device, which relates to the field of hose cutting equipment. The high-efficiency hose circumferential cutting device includes a feeder and a high-efficiency hose circumferential cutting machine. The high-efficiency hose circumferential cutting machine includes a support frame, a clamping device, a cutting device, and a driving device. The top of the support frame has a support platform. The clamping device includes a receiving cylinder, a supporting component, and multiple support frames. The multiple support frames are fixedly connected to the support platform. The receiving cylinder is mounted on the multiple support frames and is used to receive the hose. One end of the supporting component is connected to the support platform.

[0004] During the use of existing equipment, it was found that the equipment is not convenient to fix when circumferentially cutting pipes of different diameters, which affects the efficiency of pipe circumferential cutting. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a magnesium oxide circumferential cutting device that improves the convenience of clamping and positioning magnesium oxide tubes of different diameters and improves the efficiency of circumferential cutting.

[0006] This utility model discloses a magnesium oxide circumferential cutting tube device, including a cutting machine for cutting magnesium oxide tubes; it also includes a support device, a pushing device, a base, support platforms, support rollers, clamping arms, and limiting rollers. Two sets of support platforms are slidably mounted on the base, multiple sets of support rollers are rotatably mounted on the two sets of support platforms, and the tops of two sets of clamping arms are rotatably mounted on the support device, which provides elastic support for the two sets of clamping arms. Two sets of limiting rollers are rotatably mounted on the two sets of clamping arms respectively. The cutting machine is mounted on the support device, which drives the two sets of clamping arms and the cutting machine to move up and down. A pushing device is provided on the base to provide power for the sliding of the two sets of support platforms. The magnesium oxide tube to be cut is placed on the multiple sets of support rollers, and then the cutting machine is moved up and down by the support device. The support device drives two sets of clamping arms to move downwards, causing the two sets of clamping arms to move downwards and contact the upper part of the magnesium oxide tube. As the two sets of clamping arms continue to move downwards, the two sets of limiting rollers move with the outer wall of the magnesium oxide tube and push the two sets of clamping arms to swing and rotate. At this time, the support device provides elastic support to the clamping arms, allowing the two sets of limiting rollers to roll and clamp the upper part of the magnesium oxide tube. Then, the support device drives the cutting machine to move downwards to cut the magnesium oxide tube. During the cutting process, the rotation of the support rollers drives the magnesium oxide tube to rotate, thereby performing a circumferential cut on the magnesium oxide tube. By adjusting the distance between the two sets of support platforms and coordinating the downward movement distance of the two sets of clamping arms, the convenience of clamping and positioning magnesium oxide tubes of different diameters is improved, and the efficiency of circumferential cutting is increased.

[0007] Preferably, the support device includes a guide frame, a lifting platform, a first hydraulic cylinder, a first telescopic rod, a spring, and a fourth hydraulic cylinder. The guide frame is installed on the top of the base, and the lifting platform is slidably installed on the guide frame. The upper parts of multiple sets of first hydraulic cylinders are rotatably installed on the lifting platform, and the bottom ends of the multiple sets of first hydraulic cylinders are respectively connected to multiple sets of first telescopic rods. The bottom ends of the multiple sets of first telescopic rods are rotatably installed on two sets of clamping arms. Multiple sets of springs are respectively fitted onto the multiple sets of first telescopic rods. The fourth hydraulic cylinder is installed on the inner side wall of the guide frame, and the moving end of the fourth hydraulic cylinder is connected to the lifting platform. By controlling the fourth hydraulic cylinder to drive the lifting platform to move, the lifting platform drives the two sets of clamping arms to move downward, so that the two sets of clamping arms cooperate with the two sets of limiting rollers to roll and clamp the upper part of the magnesium oxide tube. At the same time, with the extension and retraction adjustment of the multiple sets of first hydraulic cylinders, it is convenient to control the elastic clamping force of the two sets of clamping arms, thereby improving the convenience of clamping magnesium oxide tubes of different diameters.

[0008] Preferably, it also includes a drive device, a slider, a second telescopic rod, and a second hydraulic cylinder. The slider is slidably mounted on the lifting platform via the drive device. The top ends of multiple sets of second telescopic rods and second hydraulic cylinders are all connected to the slider, and the moving ends of multiple sets of second telescopic rods and second hydraulic cylinders are all connected to the cutting machine. The drive device drives the slider to slide, so that the slider drives the cutting machine to move to different cutting positions. The second hydraulic cylinder drives the cutting machine to move up and down, which facilitates the cutting machine to cut the magnesium oxide tube.

[0009] Preferably, the pushing device includes a guide rail and a third hydraulic cylinder. The guide rail is set at the top of the base, and both sets of support platforms are slidably mounted on the guide rail. The two sets of third hydraulic cylinders are mounted on the outer side wall of the base, and the moving ends of the two sets of third hydraulic cylinders are connected to the two sets of support platforms. By controlling the extension and retraction adjustment of the two sets of third hydraulic cylinders, the two sets of third hydraulic cylinders drive the two sets of support platforms to slide and adjust.

[0010] Preferably, it also includes a connecting shaft and a first motor. The two ends of the connecting shaft are concentrically connected to the support rollers on one side. The first motor is installed on the outer wall of the support platform on one side, and the output end of the first motor is connected to the support rollers on one side. The first motor drives the support rollers to rotate, so that multiple sets of support rollers on one side rotate synchronously and drive the magnesium oxide tube to rotate and circumferentially cut.

[0011] Preferably, the driving device includes a lead screw and a second motor. The lead screw is rotatably mounted on the outer wall of the lifting platform, and the slider is screwed onto the lead screw. The second motor is mounted on the outer wall of the lifting platform, and the output end of the second motor is connected to the lead screw. The second motor drives the lead screw to rotate, thereby driving the slider to slide.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The magnesium oxide tube to be cut is placed on multiple sets of support rollers. Then, the support device drives two sets of clamping arms to move downward, so that the two sets of clamping arms drive two sets of limiting rollers to move downward and contact the upper part of the magnesium oxide tube. As the two sets of clamping arms continue to move downward, the two sets of limiting rollers move with the outer wall of the magnesium oxide tube and push the two sets of clamping arms to swing and rotate. At this time, the support device provides elastic support to the clamping arms, so that the two sets of limiting rollers roll and clamp the upper part of the magnesium oxide tube. Then, the support device drives the cutting machine to move downward to cut the magnesium oxide tube. During the cutting process, the rotation of the support rollers drives the magnesium oxide tube to rotate, thereby making the magnesium oxide tube ring cut. By adjusting the distance between the two sets of support platforms and by coordinating the downward movement distance of the two sets of clamping arms, the convenience of clamping and positioning magnesium oxide tubes of different diameters is improved, and the ring cutting processing efficiency is improved.

Then, the support device drives two sets of clamping arms 4 to move downward, causing the two sets of clamping arms 4 to drive two sets of limiting rollers 5 to move downward and contact the upper part of the magnesium oxide tube.

Then, the support device drives the cutting machine 6 to move downward to cut the magnesium oxide tube. During the cutting process, the rotation of the support rollers 3 drives the magnesium oxide tube to rotate, thereby making the magnesium oxide tube circumferentially cut.

At the same time, the extension and retraction adjustment of multiple sets of first hydraulic cylinders 9 facilitates the control of the elastic clamping force of the two sets of clamping arms 4, improving the convenience of clamping magnesium oxide tubes of different diameters.

[0018] This utility model discloses a magnesium oxide circumferential cutting tube device. During operation, the magnesium oxide tube to be cut is placed on multiple sets of support rollers 3. Then, a support device drives two sets of clamping arms 4 downwards, causing the clamping arms 4 to move downwards along with two sets of limiting rollers 5 to contact the upper part of the magnesium oxide tube. As the clamping arms 4 continue to move downwards, the limiting rollers 5 move along with the outer wall of the magnesium oxide tube, pushing the clamping arms 4 to swing and rotate. At this time, the support device provides elastic support to the clamping arms 4, allowing the limiting rollers 5 to roll and clamp the upper part of the magnesium oxide tube. Then, the support device drives the cutting machine 6 downwards to cut the magnesium oxide tube. During the cutting process, the rotation of the support rollers 3 causes the magnesium oxide tube to rotate, thus performing circumferential cutting.
