Description

Technical Field

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

[0002] In the processing of hydraulic pipes, it is necessary to cut the hydraulic pipes into segments of different lengths to meet actual production needs. Traditional hydraulic pipe cutting often involves operators holding a cutting machine to cut the hydraulic pipe directly. The hydraulic pipe will shake with the cutting machine, reducing the cutting accuracy. Existing methods mostly use mechanical cutting. For example, patent application number 202022696128.X discloses a hydraulic pipe cutting device, which solves the problem of lacking a simple device for cutting hydraulic pipes. However, it has problems such as not being able to fix the hydraulic pipe from both sides of the cutting position, poor stability affecting the cutting quality of the hydraulic pipe, and low efficiency in unloading the cut hydraulic pipe segments.

[0003] Based on this, the applicant proposes a cutting device for hydraulic pipe processing. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of existing hydraulic pipe cutting devices, such as the inability to fix the hydraulic pipe from both sides of the cutting position, poor stability affecting the cutting quality of the hydraulic pipe, and low efficiency in unloading the cut hydraulic pipe segments. The invention provides a hydraulic pipe processing cutting device with a reasonable structural design, which can fix the hydraulic pipe from both sides of the cutting position, has high stability to enhance the cutting quality of the hydraulic pipe, and can quickly remove the cut hydraulic pipe segments.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] A hydraulic pipe cutting device includes an operating table, a supporting structure, and a cutting structure. The operating table is mounted on a support, and includes columns and a drive structure. A top plate is mounted on the top of the columns, and a pushing structure is mounted on the top plate. The supporting structure is positioned between the columns and is movably connected to the drive structure. The hydraulic pipe to be cut is placed on the supporting structure. The drive structure can adjust the position of the supporting structure, facilitating the positioning of the hydraulic pipe at different locations, improving the stability of the hydraulic pipe during the cutting process, and enhancing the cutting quality. The cutting structure includes a cutting motor and a cutting wheel. The cutting motor is connected to the push structure, and a drive shaft is mounted on the cutting motor. A mounting ring is mounted on the cutting wheel and installed on the drive shaft. Under the action of the push structure, the cutting motor can move laterally and longitudinally, driving the cutting wheel to move laterally and longitudinally. The cutting motor drives the drive shaft and the cutting wheel mounted on the drive shaft to rotate, causing the cutting wheel to cut the hydraulic pipe placed on the supporting structure, thereby improving the cutting efficiency of the hydraulic pipe.

[0007] Preferably, the supporting structure includes a fixed plate and a supporting plate. The fixed plate is disposed between the columns, and the supporting plate is movably connected to the fixed plate on opposite sides. The bottom of the supporting plate is movably connected to the driving structure. A supporting block is disposed on the top of the supporting plate, and a supporting groove is disposed on the supporting block. The hydraulic pipe to be cut is placed in the supporting groove, which can fix the hydraulic pipe during the cutting process, enhance the stability of the hydraulic pipe during the cutting process, and thus improve the cutting quality of the hydraulic pipe. In order to improve the versatility of the cutting device and expand its application range, a supporting plate with a corresponding supporting groove can be selected according to the hydraulic pipe of different thicknesses to further enhance the stability of the hydraulic pipe during the cutting process. Multiple supporting grooves are disposed on the supporting block, which can accommodate multiple hydraulic pipes, making it convenient to cut multiple hydraulic pipes at the same time, thereby improving the cutting efficiency of the hydraulic pipe.

[0008] Preferably, the fixed plate is provided with a fixing groove, and the bearing plate is provided with crossbars on opposite sides. The crossbars are inserted into the fixing grooves, and the driving structure drives the bearing plate to move back and forth, so that the crossbars on the bearing plate move back and forth in the fixing grooves. This can reduce the resistance encountered by the bearing plate during the back and forth movement and improve the stability of the bearing plate during the position adjustment process. By adjusting the position of the bearing plate, the hydraulic pipe can be clamped at different positions, which can enhance the stability of the hydraulic pipe during the cutting process and improve the cutting quality of the hydraulic pipe.

[0009] Preferably, the drive structure includes a drive motor and a drive gear, with the drive motor configured as a servo motor. The drive motor is located at the bottom of the operating table, and a drive shaft is mounted on the drive motor. The drive gear is mounted on the drive shaft, and a connecting gear is located at the bottom of the support plate, meshing with the drive gear. The drive motor drives the drive shaft and the drive gear on the drive shaft to rotate forward or backward. The drive gear drives the connecting gear to move back and forth, thereby causing the support plate to move laterally between the fixed plates. This facilitates the adjustment of the position of the support block, fixes the hydraulic pipe at different positions, improves the stability of the hydraulic pipe during the cutting process, and enhances the cutting quality of the hydraulic pipe.

[0010] Preferably, the bearing plates are distributed on both sides of the drive gear, and the bearing grooves on the bearing blocks of the two bearing plates are set to correspond one-to-one. The drive motor drives the drive shaft and the drive gear on the drive shaft to rotate in the forward or reverse direction. The drive gear drives the connecting rack to move back and forth, so that the distance between the two bearing plates increases or decreases. The hydraulic pipe is placed in the bearing groove on the bearing block. The bearing blocks on the two bearing plates fix the hydraulic pipe from both sides of the hydraulic pipe cutting position, which enhances the cutting quality of the hydraulic pipe. After the hydraulic pipe is cut, the drive gear pushes the connecting rack to push the two bearing plates to continue to increase the distance, which makes it easier for the workers to remove the cut hydraulic pipe section from the bearing block and improves the material feeding efficiency of the hydraulic pipe.

[0011] Preferably, the pushing structure includes a first hydraulic cylinder, a moving plate, and a second hydraulic cylinder. A through groove is provided on the top plate, and a vertical plate is provided on the top plate at one end of the through groove. The first hydraulic cylinder is mounted on the vertical plate and has a piston rod. The moving plate is movably connected to the top plate and is connected to the piston rod. The second hydraulic cylinder is mounted on the moving plate and has a piston rod. The piston rod extends through the through groove and is connected to the cutting motor. The first hydraulic cylinder and the first piston rod push the moving plate laterally, causing the moving plate to drive the second hydraulic cylinder laterally. The second hydraulic cylinder and the second piston rod vertically drive the cutting motor and the cutting wheel to move vertically, causing the cutting wheel to move laterally and vertically under the action of the first and second hydraulic cylinders, sequentially cutting the hydraulic pipes in the bearing groove, thereby improving the cutting efficiency and quality of the hydraulic pipes.

[0012] Preferably, the top plates on both sides of the through groove are provided with slide rails, and the back of the movable plate is provided with a slider, which is engaged with the slide rail. The movable plate moves laterally along the slide rail under the action of the hydraulic rod, and the slider moves back and forth on the slide rail, thereby improving the stability of the movable plate during the back and forth movement.

[0013] Preferably, the cutting wheel is designed to be replaceable on the drive shaft via a mounting ring. The mounting ring on the cutting wheel is connected to the drive shaft via a thread, which improves the installation efficiency and stability of the cutting wheel on the drive shaft, thereby improving the cutting efficiency and quality of the hydraulic pipe. According to the cutting requirements of the hydraulic pipe, the appropriate cutting wheel can be selected, which can not only improve the cutting quality of the hydraulic pipe, but also expand the versatility of the cutting equipment and reduce the cost of manufacturing multiple sets of equipment.

[0014] Beneficial effects:

[0015] 1. Placing the hydraulic pipe to be cut in the bearing groove can fix the hydraulic pipe during the cutting process, enhance the stability of the hydraulic pipe during the cutting process, and thus improve the cutting quality of the hydraulic pipe. In order to improve the versatility of the cutting device and expand its application range, a bearing plate with a corresponding bearing groove can be selected according to the hydraulic pipe of different thicknesses to further enhance the stability of the hydraulic pipe during the cutting process.

[0016] 2. Place the hydraulic pipe in the bearing groove on the bearing block. The bearing blocks on the two bearing plates fix the hydraulic pipe from both sides of the cutting position to enhance the cutting quality of the hydraulic pipe. After the hydraulic pipe is cut, the drive gear pushes the connecting rack to push the two bearing plates to continue to widen the distance, making it easier for workers to remove the cut hydraulic pipe section from the bearing block and improving the material feeding efficiency of the hydraulic pipe.

[0017] 3. Connect the mounting ring on the cutting wheel to the drive shaft via a threaded connection to improve the installation efficiency and stability of the cutting wheel on the drive shaft, thereby improving the cutting efficiency and quality of the hydraulic pipe. Select the appropriate cutting wheel according to the cutting requirements of the hydraulic pipe, which can not only improve the cutting quality of the hydraulic pipe, but also expand the versatility of the cutting equipment and reduce the cost of manufacturing multiple sets of equipment.

[0032] Example 2:

[0033] Further explanation is provided based on Example 1, see appendix. Figure 6 As shown, a cutting device for hydraulic pipe processing has a dust collection chamber 28 at the bottom of the operating table 1, an exhaust pipe 29 at the bottom of the dust collection chamber 28, a filter screen 30 inside the dust collection chamber 28, and an exhaust fan 31 inside the exhaust pipe 29. During the hydraulic pipe cutting process, the exhaust fan 31 discharges the airflow from the dust collection chamber 28, creating a negative pressure inside the dust collection chamber 28.

The filter screen 30 filters the airflow and debris, keeping the debris in the dust collection chamber 28 for easy collection and improved environmental performance.

[0034] Working principle: Based on the different outer diameters of the hydraulic pipe, select the corresponding bearing plate 9 of the bearing block 11 in the bearing groove 14. Place the crossbar 13 on the bearing plate 9 into the fixed groove 10. Engage the connecting gear 12 on the moving plate 19 with the drive gear 7. Select the corresponding cutting wheel 25 according to the cutting requirements of the hydraulic pipe. Install the mounting ring 27 on the cutting wheel 25 onto the drive shaft 26. Place the hydraulic pipe to be cut into the bearing groove 14. Start the drive motor 5. The drive motor 5 drives the drive shaft 6 and the drive gear 7 on the drive shaft 6 to rotate forward or backward. The drive gear 7 drives the connecting gear 12 to move back and forth, thereby causing the bearing plate 9 to move laterally between the fixed plates 8. The bearing blocks 11 on the two bearing plates 9 fix the hydraulic pipe from both sides of the cutting position, enhancing the cutting quality of the hydraulic pipe and facilitating adjustment. The position of the bearing block 11 is fixed at different positions of the hydraulic pipe. The hydraulic cylinder 18, hydraulic cylinder 20, and cutting motor 24 are started. The hydraulic cylinder 18 and piston rod 21 push the moving plate 19 to move laterally, so that the moving plate 19 drives the hydraulic cylinder 20 to move laterally. The hydraulic cylinder 20 and piston rod 23 drive the cutting motor 24 and cutting wheel 25 to move vertically, so that the cutting wheel 25 moves laterally and vertically under the action of the hydraulic cylinder 18 and hydraulic cylinder 20. The cutting motor 24 drives the transmission shaft 26 and the cutting wheel 25 mounted on the transmission shaft 26 to rotate, so that the cutting wheel 25 cuts the hydraulic pipe placed on the bearing structure. After the hydraulic pipe is cut, the drive gear 7 pushes the connecting rack 12 to push the two bearing plates 9 to continue to widen the distance, so that the workers can remove the cut hydraulic pipe section from the bearing block 11.
