Description

Technical Field

[0001] This utility model belongs to the technical field of chamfering equipment, specifically a steel pipe chamfering device. Background Technology

[0002] With the rapid development of my country's economy, the market demand for steel pipes, a common steel product, continues to grow. In the finishing process of steel pipes, end face chamfering is one of the most crucial steps. The chamfering machine, as the core equipment, performs fine processing on the end faces of the steel pipes during the process, making them smoother and removing burrs, thereby improving product quality. With continuous technological advancements, the precision and efficiency of the chamfering process are constantly improving to meet the market demand for high-quality steel pipe products.

[0003] Currently, various methods have been proposed for steel pipe chamfering devices. For example, patent application CN220839139U discloses a steel pipe chamfering machine. The steel pipe is fixed to a clamping assembly. A motor is started, driving a rotating disk to rotate, which in turn drives a cutting tool to rotate around the axis of the rotating disk, i.e., around the axis of the steel pipe. A hydraulic cylinder is activated, causing a connecting plate and the cutting tool to move closer to the steel pipe. The rotating cutting tool cuts and chamfers the steel pipe until it reaches the appropriate position, completing the chamfering process. The hydraulic cylinder then retracts, causing the cutting tool to leave the steel pipe surface. During its movement, the connecting plate is guided by a guide rod and a guide sleeve. However, the cutting tool generates a large amount of friction and heat during the chamfering process, leading to overheating and tool failure. Excessive temperature can cause localized expansion or thermal deformation of the workpiece, affecting processing accuracy. Furthermore, it generates a large amount of metal dust, which not only affects the health of operators but also pollutes the equipment.

[0004] Therefore, this utility model provides a steel pipe chamfering device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a steel pipe chamfering device includes a workbench 1. A bracket 2 is fixedly connected to the upper end of the workbench 1. A rectangular sleeve 6 is rotatably connected to the upper inner wall of the bracket 2. A rectangular sliding sleeve 7 is slidably connected inside the rectangular sleeve 6. A rectangular plate 20 is fixedly connected to the lower end of the rectangular sliding sleeve 7. A second short rod 21 is rotatably connected inside the rectangular plate 20. One end of the second short rod 21 is fixedly connected to the lower end of the rectangular sliding sleeve 7, and the other end of the second short rod 21 is fixedly connected to a turntable 22. A chamfering cutter 23 is provided at the lower end of the turntable 22. A first short rod 19 is fixedly connected to the upper end of the rectangular sleeve 6. A driving gear 5 is fixedly connected to the upper end of the first short rod 19. The first short rod 19 passes through the rotating bracket 2. A driven gear 3 is rotatably connected to the upper end of the bracket 2. The driven gear 3 is connected to the driving gear 5. The driven gear 5 is engaged, and the lower end of the driven gear 3 is fixedly connected to a reciprocating screw 15. The reciprocating screw 15 passes through the rotating bracket 2, and a nut 16 is threaded onto the reciprocating screw 15. A connecting rod 17 is fixedly connected to the side wall of the nut 16. A water tank 11 and a rectangular cylinder 13 are fixedly connected to the upper end of the workbench 1. The water tank 11 and the rectangular cylinder 13 are connected through a water inlet pipe 12. A water outlet pipe 14 is connected to the side wall of the rectangular cylinder 13. The end of the water outlet pipe 14 away from the rectangular cylinder 13 is fixedly installed at the lower end of the rectangular plate 20. A square plug 18 is slidably connected inside the rectangular cylinder 13. The end of the connecting rod 17 away from the nut 16 is fixedly connected to the square plug 18. A guide mechanism for guiding the nut 16 is installed on the bracket 2, and a clamping mechanism for clamping the steel pipe is installed on the upper end of the workbench 1. During operation, the driving gear 5 drives the driven gear 3 to rotate, and the driven gear 3 drives the reciprocating screw 15 to rotate. The rotation of the reciprocating screw 15 causes the nut 16 to move up and down along the guide rod 24. The nut 16 drives the square plug 18 to move back and forth inside the rectangular cylinder 13 through the connecting rod 17, so that the water in the water tank 11 enters the rectangular cylinder 13 and is sprayed out through the water outlet pipe 14 to the vicinity of the chamfering knife 23, which can cool the chamfering knife 23 during chamfering.

[0025] like Figure 1As shown, a motor 4 is fixedly connected to the upper end of the bracket 2, and the output shaft of the motor 4 is fixedly connected to the drive gear 5. During operation, the motor 4 is started, and the motor 4 drives the drive gear 5 to rotate. Through the above structure, the drive gear 5 drives the driven gear 3 and the first short rod 19 to rotate, thereby causing the water outlet pipe 14 to spray water to the vicinity for cooling when the chamfering blade 23 rotates.

[0026] like Figure 1 and Figure 4 As shown, the guiding mechanism includes a guide rod 24. One end of the guide rod 24 is fixedly installed on the upper inner end of the bracket 2, and the other end is fixedly installed on the upper end of the worktable 1. The nut 16 slides on the guide rod 24, and the guide rod 24 passes through the nut 16. During operation, the nut 16 moves along the guide rod 24. Through the above structure, the guide rod 24 limits the nut 16, ensuring that the nut 16 can only slide along the guide rod 24, preventing the nut 16 from deviating during movement.

[0027] like Figure 1 As shown, the clamping mechanism includes two first electric telescopic rods 8 and two clamps 9. Each first electric telescopic rod 8 is fixedly installed on the upper end of the worktable 1, and each clamp 9 is fixedly installed on the output end of the first electric telescopic rod 8. During operation, the first electric telescopic rod 8 is activated, causing it to move the two clamps 9 closer together, thereby clamping and fixing the steel pipe. This structure prevents the steel pipe from wobbling during the chamfering process, improving processing accuracy.

[0028] like Figure 1 As shown, a steel pipe groove 25 is provided at the upper end of the worktable 1, and four fixed columns 10 are fixedly connected to the lower end of the worktable 1. Through the above structure, the four fixed columns 10 support the worktable 1, providing a stable foundation, reducing processing errors caused by vibration, and improving chamfering accuracy. The steel pipe groove 25 helps to accurately place the steel pipe to be processed, avoids the steel pipe from rolling or shifting, improves clamping stability, and ensures that the chamfering cutter 23 cuts evenly.

[0029] like Figure 1 As shown, two second electric telescopic rods 26 are fixedly connected to the upper inner wall of the bracket 2. The telescopic ends of the second electric telescopic rods 26 are fixedly connected to the upper end of the rectangular plate 20. During operation, activating the second electric telescopic rods 26 can move the rectangular plate 20 up and down, thereby controlling the position of the chamfering cutter 23, making the contact between the chamfering cutter 23 and the steel pipe more stable and improving the chamfering accuracy.

[0030] like Figure 1 and Figure 2As shown, one-way valves are installed in the inlet pipe 12 and the outlet pipe 14. During operation, when the square plug 18 moves upward, the one-way valve in the inlet pipe 12 opens and the one-way valve in the outlet pipe 14 closes, allowing water in the water tank 11 to enter the rectangular cylinder 13 through the inlet pipe 12. At this time, water in the rectangular cylinder 13 cannot be discharged through the outlet pipe 14. When the square plug 18 moves downward, the one-way valve in the inlet pipe 12 closes and the one-way valve in the outlet pipe 14 opens, allowing water in the rectangular cylinder 13 to spray out through the outlet pipe 14 towards the vicinity of the chamfered blade 23. At this time, water in the water tank 11 cannot enter the rectangular cylinder 13 through the inlet pipe 12.

[0031] Working principle: The steel pipe to be chamfered is placed in the steel pipe groove 25. The first electric telescopic rod 8 is activated, causing the two clamps 9 to move closer together, thus clamping and fixing the steel pipe. The motor 4 is activated, which drives the drive gear 5 to rotate. The drive gear 5 drives the first short rod 19 to rotate, which in turn drives the rectangular sleeve 6 to rotate. The rectangular sleeve 6 drives the rectangular sliding sleeve 7 to rotate, which in turn drives the turntable 22 to rotate via the second short rod 21. This causes the chamfering blade 23 to rotate, and the chamfering blade 23 is used to chamfer the steel pipe. At the same time, when the second electric telescopic rod 26 is activated and moves the rectangular plate 20, the rectangular sliding sleeve 7 moves within the rectangular sleeve 6. Due to the rectangular design of the rectangular sleeve 6 and the rectangular sliding sleeve 7, the rectangular sleeve 6 can drive the rectangular sliding sleeve 7 to rotate, and the rectangular sliding sleeve 7 can also move undisturbed within the rectangular sleeve 6.

[0032] At the same time, the driving gear 5 drives the driven gear 3 to rotate, and the driven gear 3 drives the reciprocating screw 15 to rotate. The rotation of the reciprocating screw 15 causes the nut 16 to move up and down along the guide rod 24. It should be noted that the reciprocating screw 15 only has threads on its lower part, which means that the nut 16 can only move on the lower part of the reciprocating screw 15. At the same time, the threads on the reciprocating screw 15 are densely distributed, so even when the reciprocating screw 15 rotates at high speed, the nut 16 can still maintain a certain speed of movement on the reciprocating screw 15. Nut 16 drives square plug 18 to reciprocate within rectangular cylinder 13 via connecting rod 17. When square plug 18 moves upward, the one-way valve in inlet pipe 12 ensures that water in water tank 11 can only flow into rectangular cylinder 13 for temporary storage. When square plug 18 moves downward, the one-way valve in outlet pipe 14 ensures that water in rectangular cylinder 13 can only spray out near chamfered blade 23 through outlet pipe 14, preventing chamfered blade 23 from overheating. The outlet pipe 14 is a flexible, extendable hose, ensuring that the movement of rectangular plate 20 does not affect the outlet pipe 14, and the deformation of the outlet pipe 14 can accommodate the movement of rectangular plate 20.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
