Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and more specifically, to a valve pipe cutting device with an adjustable cutting blade angle. Background Technology

[0002] Valves and pipelines are widely used in modern industrial production and construction. Whether in petrochemicals, water supply and drainage systems, HVAC, or many other fields, valves and pipelines play a vital role.

[0003] In practical applications, the layout of pipelines can be quite complex. Different installation environments and engineering requirements result in different cutting angles for pipelines, requiring cutting at specific angles to successfully complete installation or maintenance work.

[0004] A search revealed that Chinese Patent CN220127726U discloses a steel pipe cutting device with an adjustable cutting angle. In use, a clamping mechanism can clamp and fix the steel pipe, and the clamping mechanism can adjust the cutting angle to achieve a bevel cutting effect. During cutting, a marking mechanism can mark the cutting position for easy observation. The hydraulic cylinder operates, causing the hydraulic rod to push the cutting machine downwards to cut the steel pipe. Thus, the cutting angle can be adjusted for bevel cutting, and the cut point can be marked.

[0005] However, in actual use, the equipment can only cut one pipe at a time, which is not very efficient. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a valve and pipe cutting device with adjustable cutter angle to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a valve pipe cutting device with adjustable cutter angle, comprising a base, a support frame fixedly connected to the top of the base, a pressing mechanism provided at the top of the support frame, a rotating mechanism provided at the bottom of the pressing mechanism, a cutting mechanism provided at the bottom of the rotating mechanism, and a fixing mechanism provided at the top of the base.

[0008] The fixing mechanism includes two support seats fixedly connected to the top of the base. A lead screw is rotatably connected between the support seats and the base. A first motor is fixedly installed on the top of one of the support seats. The output end of the first motor is fixedly connected to the top of the lead screw. A fixing plate is provided between the two lead screws. Three grooves are opened on the top of the base. Cutting grooves are opened inside the grooves.

[0009] The cutting mechanism includes a placement chamber, in which a second motor is fixedly installed. A protective cover is fixedly connected to one side of the placement chamber, and a rotating rod is rotatably connected inside the protective cover. Multiple through holes are provided on the outer wall of the placement chamber. The output end of the second motor passes through the placement chamber and one end of the protective cover and extends into the interior of the protective cover, where it is fixedly connected to the rotating rod. A cutting blade is fixedly connected to the outer wall of the rotating rod.

[0010] In order to achieve the effect of controlling the cutting mechanism to cut the pipe during cutting, preferably, the pressing mechanism includes a fixed seat fixedly connected to the top of the support frame, a cylinder fixedly installed at the top of the fixed seat, the output end of the cylinder passing through the fixed seat, and the output end of the cylinder extending to the bottom of the fixed seat and fixedly connected to a pressing plate, and three fixed columns fixedly connected to the bottom of the pressing plate, one end of each of the three fixed columns passing through the support frame.

[0011] To achieve the effect of adjusting the cutting angle, preferably, the rotating mechanism includes a disc fixedly connected to the bottom of a fixed column, a scale plate at the bottom of the disc, a limiting mechanism at the top of the scale plate, a rotating disk between the disc and the scale plate, a pointer fixedly connected to one side of the rotating disk, a rotating column fixedly connected to the bottom of the rotating disk and passing through the scale plate, a rotating rod fixedly connected to one side of the rotating column, and the bottom of the rotating column fixedly connected to the placement chamber.

[0012] In order to achieve the effect of placing the device in a position where the cutting angle may shift due to vibration or other factors during cutting, preferably, the limiting mechanism includes two connecting rods fixedly connected to the top of the dial. Both connecting rods pass through the dial and extend to the top of the dial, and one end of each connecting rod is threaded with a nut.

[0013] To achieve the effect of simultaneously fixing three pipes, preferably, the fixing plate includes a receiving plate threadedly connected to the lead screw, the receiving plate is set at the bottom of the support base, and both ends of the two receiving plates are provided with arc-shaped plates, and the bottom end of the arc-shaped plates is fixedly connected with a rubber ring.

[0014] To achieve stronger support and rust prevention for the support frame, preferably, the support frame is made of aluminum alloy and has an anti-rust coating sprayed on its surface.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By setting up a fixing mechanism, a pressing mechanism, and a cutting mechanism, the first motor is started to drive the lead screw to rotate, causing the fixing plate to move downward to fix the pipe. It can fix pipes of various sizes, and can fix multiple pipes of the same size at the same time, which facilitates subsequent cutting. Then, the second motor is started, which drives the cutting blade on the rotating rod to rotate. At this time, the cylinder is started, and the cylinder drives the pressing plate and the fixing column, causing the cutting mechanism to move downward to cut the pipe. Multiple pipes can be cut at the same time, reducing cutting time and thus improving work efficiency.

[0017] By setting up a rotating mechanism and a limiting mechanism, by loosening the nut and rotating the rotating rod, the rotating rod drives the rotating column and the pointer on the rotating disk. By observing the angle of the pointer's rotation, the cutting mechanism is determined to be rotated to the designated position. By setting up three rotating columns, three pipes with the same angle or three pipes with different angles can be cut. After adjusting the rotating disk, tightening the nut limits the rotating disk to prevent it from shifting due to vibration during cutting, which would affect the cutting angle.

Three fixed columns 16 are fixedly connected to the bottom of the pressing plate 15. One end of each of the three fixed columns 16 passes through the support frame 2, so as to control the cutting mechanism to cut the pipe during cutting.

[0031] Specifically, in this structure, by activating cylinder 14, cylinder 14 drives pressing plate 15 to press the fixed seat 16 downward.

[0032] In a specific embodiment, as shown in the appendix Figure 2 , 5 As shown, the rotating mechanism includes a disc 17 fixedly connected to the bottom of the fixed column 16. A scale 18 is provided at the bottom of the disc 17, and a limiting mechanism is provided at the top of the scale 18. A rotating disk 19 is provided between the disc 17 and the scale 18. A pointer 20 is fixedly connected to one side of the rotating disk 19. A rotating column 21 is fixedly connected to the bottom of the rotating disk 19 and passes through the scale 18. A rotating rod 22 is fixedly connected to one side of the rotating column 21.

[0034] In a specific embodiment, as shown in the appendix Figure 5 As shown, the limiting mechanism includes two connecting rods 23 fixedly connected to the top of the dial 18. Both connecting rods 23 pass through the disc 17 and extend to the top of the disc 17.

[0035] Specifically, in this structure, the rotating mechanism is rotated by loosening the nut 24, and the disc 17 and the scale 18 clamp the rotating disc 19 by tightening the nut 24 on the connecting rod 23.

[0036] In a specific embodiment, as shown in the appendix Figure 1 , 3 As shown, the fixing plate includes a receiving plate 25 that is threadedly connected to the lead screw 4. The receiving plate 25 is set at the bottom of the support base 3. Both ends of the two receiving plates 25 are provided with arc-shaped plates 26.

[0037] Specifically, in this structure, the fixing plate is set to be arc-shaped, and a rubber ring 27 is fixed at the bottom.

[0038] In a specific embodiment, as shown in the appendix Figure 1 , 2 As shown, the support frame 2 is made of aluminum alloy and has an anti-rust coating on its surface to provide stronger support.

[0039] Specifically, the structure is made more robust by using an aluminum alloy support frame and spraying a rust-proof coating on its surface.

[0040] The working principle of this utility model is as follows: When in use, three pipes of the same size are first placed in the groove 6. Then, the first motor 5 is started, which drives the lead screw 4 to rotate, thereby moving the fixing plate up and down and clamping the pipes. Then, by loosening the nut 24, the rotating rod 22 is rotated. The rotating rod 22 drives the pointer 20 on the turntable and the cutting mechanism at the bottom of the rotating column 21, thereby changing the cutting angle. When changing, three identical or different cutting angles can be selected. After the change is completed, the nut 24 is tightened and the cylinder 14 and the second motor 9 are started. The cylinder 14 drives the pressing plate 15 to press down. Then, the second motor 9 drives the cutting blade 12 on the rotating rod 11 to cut the pipes.

[0041] When the cutting is completed, the second motor 9 is turned off, and then the cylinder 14 is started. The cylinder 14 drives the pressing plate 15 to rise, and then the pressing plate 15 drives the fixing column 16 to rise. When the fixing column 16 rises, it drives the rotating mechanism and the cutting mechanism to move upward together. After moving to a certain position, the cylinder 14 is turned off and the first motor 5 is started. The first motor 5 drives the fixing plate to move up and down, so that the fixing plate releases the clamp on the pipe, and then the pipe is taken out.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
