Description

Technical Field

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

[0002] Pipe fittings are critical components in piping systems used to connect, control, or change the direction of pipelines. Their machining accuracy directly affects the sealing performance, pressure resistance, and service life of the piping system. Machining is one of the core processes in pipe fitting manufacturing; its essence is to use cutting forces to deform and fracture the workpiece material, thereby achieving material separation.

[0003] Existing patent document CN217192923U discloses a cutting device for processing automotive air conditioning pipe joints. The device includes a cutting device housing, an internal cutting mechanism, an intermittent feeding mechanism on the outer wall of the housing, an L-shaped limiting plate below the cutting mechanism, a movable component below the L-shaped limiting plate, a first insert rod on the movable component, a push ring below the first insert rod, a support rod below the push ring, a base plate below the intermittent feeding mechanism, a support plate on the base plate, a second insert rod on the support plate, and a limiting pin on the second insert rod. This invention, through a series of structural features, avoids product accumulation, facilitates processing in the next step, and achieves automatic feeding without manual operation.

[0004] However, in the process of using existing cutting devices for pipe joint processing, although the cutting devices can achieve automatic feeding without manual operation, in actual operation and processing, the pipe material may be bent or deformed due to various reasons during transportation. However, the feeding device can straighten the pipe, which leads to a decrease in processing accuracy and causes abnormal wear or chipping of the tool, shortening the tool life. Therefore, we propose a cutting device for pipe joint processing. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cutting device for processing pipe joints, including a cutting body 1, an adjustment groove 9 on the top of the cutting body 1, a lifting rod 3 embedded in the front of the cutting body 1, a mounting platform 4 bolted to the top of the lifting rod 3, a drive shaft 701 movably connected through the side of the top of the cutting body 1 away from the adjustment groove 9, a straightening main wheel 7 sleeved on the top of the drive shaft 701, an adjustment rod 10 bolted to the back of the cutting body 1, a sliding frame 11 fixedly connected to one end of the adjustment rod 10, a rotating shaft 801 fixedly connected to the top of the sliding frame 11 via a bearing, a straightening secondary wheel 8 keyed to the top of the rotating shaft 801, a drive motor 12 installed inside the cutting body 1, and a drive wheel 13 keyed to the drive end of the drive motor 12.

[0024] Furthermore, a cutting motor 5 is installed on the top of the mounting platform 4. The drive end of the cutting motor 5 is keyed to the cutting disc 6. The cutting motor 5 drives the cutting disc 6 to rotate, and at the same time, the lifting rod 3 drives the cutting component to move downward, so that the cutting disc 6 can cut the pipeline.

[0025] Furthermore, the bottom of the cutting body 1 is threaded with support legs 2. There are four support legs 2, which are located at the four corners of the bottom of the cutting body 1. The support legs 2 make the device more stable and less prone to shaking.

[0026] Furthermore, the bottom end of the drive shaft 701 will be connected to a drive wheel 702. There are three drive wheels 702, and all three drive wheels 702 are double-groove structures. The double-groove structure of the drive wheels 702 allows the drive belt 14 to be installed according to the transmission requirements.

[0027] Furthermore, a transmission toothed belt 14 is connected to the outer side of the drive wheel 13. The transmission toothed belt 14 is connected to the drive wheel 702. The transmission toothed belt 14 can play a transmission role, so that the drive motor 12 drives the transmission toothed belt 14 to rotate through the drive wheel 13. The transmission toothed belt 14 drives the drive shaft 701 to rotate through the drive wheel 702. The drive shaft 701 simultaneously drives the straightening main wheel 7 to rotate.

[0028] Furthermore, there are three straightening main wheels 7 and three straightening auxiliary wheels 8. The three straightening main wheels 7 and straightening auxiliary wheels 8 are arranged in pairs. The straightening main wheels 7 and straightening auxiliary wheels 8 can be used to transport and straighten the pipeline.

[0029] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the cutting device for pipe joint processing, the worker places the pipe between the straightening main wheel 7 and the straightening auxiliary wheel 8. Then, the adjusting rod 10 is activated. The adjusting rod 10 pushes the sliding frame 11, causing the straightening auxiliary wheel 8 on the rotating shaft 801 to move through the adjusting groove 9. At this time, the straightening main wheel 7 and the straightening auxiliary wheel 8 can clamp the pipe. Then, the drive motor 12 is activated. The drive motor 12 drives the transmission toothed belt 14 through the drive wheel 13, and the transmission toothed belt 14 drives the transmission wheel 702. The drive shaft 701 rotates, and the drive shaft 701 simultaneously drives the straightening main wheel 7 to rotate. At this time, the straightening main wheel 7 and the straightening auxiliary wheel 8 can transport the pipeline. During the transport process, when the pipeline bends, the straightening main wheel 7 and the straightening auxiliary wheel 8 simultaneously straighten the pipeline. At this time, the pipeline can move to the cutting position, and the cutting motor 5 drives the cutting disc 6 to rotate. At the same time, the lifting rod 3 drives the cutting component to move downward, and the cutting disc 6 can cut the pipeline. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
