Description

Technical Field

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

[0002] Valves are mostly made of materials such as cast iron, cast steel, and stainless steel. Valves are generally connected to pipelines to transport media. When processing valve pipelines, valve pipeline cutting devices are needed to cut the valve pipelines.

[0003] Current cutting devices used for valve and pipe processing, if the waste is not disposed of after cutting, will affect the next use.

[0004] A search revealed that Chinese Patent CN217702549U discloses a cutting device for valve pipe processing. Through a first telescopic device and a first sliding device, a push plate is moved to push the pipe out of the support frame, facilitating material unloading and increasing the device's efficiency. Furthermore, by installing an exhaust pump on the surface of the support frame, along with an air duct and outlet, waste generated during cutting can be blown away, preventing waste residue from affecting future use and improving the device's practicality.

[0005] In actual use, the cutting device for valve and pipeline processing uses a relatively moving clamping device to clamp the valve and pipeline. However, the relatively moving clamping device is not conducive to evenly distributing the clamping force, which may cause the pipeline to shift or shake during processing, thus affecting the processing accuracy. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cutting device for valve and pipeline processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cutting device for valve and pipe processing includes a base plate. A stepper motor is fixedly connected to the front side of the base plate. A first lead screw is fixedly connected to the output end of the stepper motor. The first lead screw is rotatably connected to the inside of the base plate. A first fixing plate is threadedly connected to the outer side of the first lead screw. A second fixing plate is fixedly connected to the top of the base plate. A connecting bracket is installed on one side of the base plate. A protective cover is provided on one side of the connecting bracket. A handle is fixedly connected to one side of the protective cover. A servo motor is fixedly connected to the other side of the protective cover. A cutting blade is fixedly connected to the output end of the servo motor. The cutting blade is rotatably connected to the inside of the protective cover. A spraying mechanism is installed inside the servo motor. A clamping assembly is installed on the top of the base plate.

[0009] By adopting the above technical solution, the first fixing plate and the second fixing plate can further clamp and fix the valve pipeline, so that the valve pipeline can remain stable during cutting. The spraying mechanism and clamping components can ensure that the valve pipeline is subjected to balanced force during clamping, and at the same time, the cutting blade can be sprayed and cooled during cutting.

[0010] As a further description of the above technical solution: the clamping assembly includes a first limiting plate, which is fixedly connected to the top of the base plate. The first limiting plate has multiple first sliding grooves inside, and a sliding rod is slidably connected inside each first sliding groove. A clamping ring is fixedly connected to one end of the sliding rod, and an anti-slip pad is fixedly connected to one side of the clamping ring. A first hinge support is fixedly connected to the front side of the sliding rod, and a push rod is hinged to the inner side of the first hinge support. A second hinge support is hinged to one end of the push rod, and a second limiting plate is fixedly connected to one end of the second hinge support. A roller is rotatably connected to the bottom end of the second limiting plate. Two second sliding grooves are opened at the top of the base plate, and the roller is slidably connected to the inner side of the second sliding groove. A threaded block is fixedly connected to one side of the second limiting plate, and a second lead screw is threadedly connected inside the threaded block. One end of the second lead screw is rotatably connected to one side of the first limiting plate, and a turntable is fixedly connected to the other end of the second lead screw.

[0011] By adopting the above technical solution, a ring clamp can be performed on the outside of the valve pipeline, thereby enabling the valve pipeline to remain stable during cutting.

[0012] As a further description of the above technical solution: the spraying mechanism includes a diversion ring, which is fixedly connected to one side of the protective cover. A plurality of spray heads are connected to one side of the diversion ring, and the spray heads extend through the protective cover to the inside of the protective cover. A water leakage groove is opened inside the base plate. A water collection tank is fixedly connected to one side of the base plate. A connecting hose is connected to the other side of the diversion ring. A water pump is connected to one end of the connecting hose. A connecting pipe is connected to the input end of the water pump. A water tank is connected to one end of the connecting pipe. The water tank is installed on the top of the base plate.

[0013] By adopting the above technical solution, cooling can be achieved during cutting, which can effectively reduce the material temperature and prevent thermal deformation from affecting the cutting accuracy.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a clamping assembly, compared with the existing technology, multiple clamping rings can perform circumferential clamping on the outside of the valve pipeline, which can stably clamp the valve pipeline and prevent displacement caused by vibration or external force during the cutting process, thereby ensuring the accuracy and precision of the cutting. It can also ensure that the valve pipeline is subjected to balanced force during the clamping process and is not prone to deformation or damage.

[0016] 2. By setting up a spray mechanism, compared with the existing technology, the cutting blade can be sprayed and cooled during cutting, which reduces the cutting quality degradation or cutting blade damage caused by overheating of the cutting blade, and also reduces wear caused by overheating of the blade, thus extending the service life of the blade.

[0030] Working principle of this utility model: This utility model designs a cutting device for valve and pipeline processing, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when the valve pipeline needs to be processed and cut, the valve pipeline is first passed through the second limiting plate 14 and the first limiting plate 6 in sequence, and the part to be cut is extended to the side of the first fixed plate 4 and the second fixed plate 5. Then, the stepper motor 2 is started, and the first lead screw 3 is driven to rotate, so that the first fixed plate 4 can be moved towards the second fixed plate 5 through the thread, so that the first fixed plate 4 and the second fixed plate 5 can clamp and fix the valve pipeline. Then, the turntable 19 is rotated, and the turntable 19 drives the second lead screw 18 to rotate, so that the second lead screw 18 can drive the threaded block 17 to move through the thread, thereby driving the second limiting plate 14 to move towards the first limiting plate 6.

The slide rod 8 is slidably connected to the inside of the first slide groove 7. The first slide groove 7 can guide the movement of the slide rod 8, so that multiple slide rods 8 can drive the clamping ring 9 to perform a ring clamping on the outside of the valve pipe, thereby stably clamping and fixing the valve pipe. Then, the servo motor 20 is started, which drives the cutting blade 21 to rotate. Afterwards, the handle 29 is manually pulled down, which can lower the protective cover 22. The valve pipe is cut, and the water pump 26 is started at the same time. The water pump 26 can draw water out of the water tank 28 through the connecting pipe 27 and deliver the water to the diversion ring 23 through the connecting hose 25. The diversion ring 23 can deliver the water to multiple spray heads 24, so that the cutting blade 21 can be cooled during cutting, which can reduce the cutting temperature. The water sprayed will flow into the water leakage tank 30, and the water leakage tank 30 can deliver the water to the collection tank 31 for centralized collection and treatment.
