Description

Technical Field

[0001] This utility model relates to the field of processing and grinding, specifically to a pneumatic deburring device for the inner hole of steel pipes. Background Technology

[0002] Deburring of the inner bore of high-pressure heater heat exchanger tubes after cutting is done manually by turning a drill bit, with the drill bit head cutting away the burrs. However, existing techniques for deburring steel pipe inner bores have limitations.

[0003] 1. Traditional manual deburring

[0004] After cutting and machining, heat exchanger tubes in high-pressure heaters often develop burrs on the inner edges of their bores. The traditional manual deburring method uses a hand-operated drill bit to remove these burrs by cutting them away with the drill head. This method is extremely inefficient, especially for products with a large number of heat exchanger tubes, resulting in high labor costs. Furthermore, manual operation makes it difficult to ensure uniform deburring quality; differences in operator technique and skill level lead to inconsistent quality after deburring.

[0005] 2. Use a conical grinding wheel to remove burrs.

[0006] Using abrasive wheel grinding equipment to deburr the inner holes of steel pipes is another common method. While it improves efficiency to some extent, it also presents several problems. On the one hand, although conical grinding wheels can achieve good deburring effects on inner holes, the wheel head wears out too quickly, which is detrimental to production cost control. On the other hand, the rapid wear of conical grinding wheels necessitates frequent replacements, increasing downtime. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a pneumatic steel pipe inner hole deburring device, which includes a cutter head, one end of the cutter head is connected to a connecting rod, the other end of the connecting rod is connected to a sleeve, the other end of the sleeve is detachably connected to a rotating shaft, the sleeve is mounted on a pneumatic actuator, and the front end of the cutter head is provided with a spiral groove.

[0009] Furthermore, the included angle of the cutter head is 30°-60°.

[0010] Furthermore, the width of the spiral groove is 8-12 mm.

[0011] Furthermore, the pneumatic actuator is equipped with a control button, which is a forward and reverse control button, and the control button is responsible for starting and stopping the pneumatic actuator.

[0013] Furthermore, the sleeve is provided with an inner four-corner positioning hole at one end near the rotating shaft, and a positioning rod is provided correspondingly at one end of the rotating shaft near the sleeve.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, this pneumatic steel pipe internal hole deburring device provides rotational power through a pneumatic driver. The rotating shaft transmits the power to the sleeve, which drives the cutter head to rotate via a connecting rod. The spiral groove (8-12mm wide) at the front end of the cutter head effectively discharges chips and reduces resistance. The cutter head angle is 30°-60°, optimizing cutting performance, and the use of cemented carbide material improves durability. The sleeve and rotating shaft are precisely aligned through the inner four corner positioning holes and positioning rods, ensuring a stable connection. The forward and reverse control buttons on the pneumatic driver allow the operator to easily change the direction of cutter head rotation and start and stop the device to adapt to different processing needs.

[0022] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.

[0024] In this embodiment, a cutter head 1 is included. One end of the cutter head 1 is connected to a connecting rod 2, and the other end of the connecting rod 2 is connected to a sleeve 3. The other end of the sleeve 3 is detachably connected to a rotating shaft 6. The sleeve 3 is mounted on a pneumatic actuator 4. A spiral groove 5 is provided at the front end of the cutter head 1. This structural design allows the cutter head 1 to be flexibly connected to the pneumatic actuator 4 through the connecting rod 2 and the sleeve 3, thereby enabling the cutter head 1 to rotate effectively and transmit power during operation. The spiral groove 5 helps to effectively remove chips during deburring, reduce resistance, and improve processing efficiency.

[0025] The pneumatic actuator 4 provides power to rotate the shaft 6. The rotational motion is transmitted to the cutter head 1 via the sleeve 3 and connecting rod 2; the spiral groove 5 helps to remove burrs and chips from the cutting position, keeping the cutting area clean.

[0026] The included angle of the cutter head 1 is 30°-60°, which provides good cutting performance and stability. More preferably, the included angle of the cutter head 1 is set to 45°, which has the best burr removal effect.

[0027] The spiral groove 5 has a width of 8-12mm, providing sufficient space to remove burrs and chips, preventing burr and chip accumulation, and reducing friction and heat generation during the cutting process.

[0028] The pneumatic actuator 4 is equipped with a control button 7, which is a forward and reverse control button 7. The control button 7 is responsible for starting and stopping the pneumatic actuator 4. The forward and reverse control button 7 allows the operator to easily control the rotation direction of the cutter head 1 to adapt to different processing needs, and at the same time, it can quickly start and stop the equipment to improve work efficiency.

[0029] The cutter head 1 is made of cemented carbide, which provides excellent wear resistance and heat resistance, enabling the cutter head 1 to remain sharp and extend its service life under high-intensity and high-temperature working environments.

[0030] The sleeve 3 is provided with an inner four-corner positioning hole at one end near the rotating shaft 6, and a positioning rod is provided at the corresponding end of the rotating shaft 6 near the sleeve 3. The cooperation between the inner four-corner positioning hole and the positioning rod ensures the precise alignment and stable connection between the sleeve 3 and the rotating shaft 6, preventing offset or loosening during high-speed rotation.

[0031] Working Process: The device is powered by a pneumatic actuator 4, which transmits power to the sleeve 3 via the rotating shaft 6. The sleeve 3 drives the cutter head 1 to rotate via the connecting rod 2. The spiral groove 5 (8-12mm wide) at the front end of the cutter head 1 effectively removes chips and reduces resistance. The cutter head 1 has an included angle of 30°-60°, optimizing cutting performance, and is made of carbide to improve durability. The sleeve 3 and the rotating shaft 6 are precisely aligned via internal four-corner positioning holes and positioning rods to ensure a stable connection. The forward and reverse control buttons 7 on the pneumatic actuator 4 allow the operator to easily change the rotation direction of the cutter head 1 and start and stop the device to adapt to different processing needs. The overall design improves cutting efficiency and stability.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
