Description

Technical Field

[0001] This utility model relates to the field of cabinet processing, and in particular to a steel pipe end reaming machine. Background Technology

[0002] Metal tubes are often used in the manufacturing process of cabinets or tables and chairs. Sometimes, for easier connection, it is necessary to use a hole expander to enlarge the ends of the steel tubes.

[0003] A search revealed a Chinese patent publication number CN221388547U, which discloses a copper tube reaming machine. This patent uses a servo motor as a power source to drive a threaded screw, thereby changing the lateral position of the reaming component. By changing the position of each reaming cone at the bottom of the mounting plate, the power cylinder can drive the corresponding reaming cone to move up and down, realizing the reaming of steel tubes with different diameters. It is adaptable to different reaming requirements and has strong applicability.

[0004] Most existing technologies directly drive the reaming cone to move through a hydraulic cylinder, gradually extending it into the steel pipe to expand the hole. However, direct insertion results in greater friction between the steel pipe and the reaming cone, making it difficult for the reaming cone to enter and exit the steel pipe. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, a steel pipe end reaming machine includes a base 1. The top of the base 1 is provided with a fixing mechanism for clamping the steel pipe. The fixing mechanism includes multiple sets of support seats 201 bolted to the top of the base 1. The top of the support seat 201 has an arc-shaped groove, and the steel pipe is placed in the arc-shaped groove. A mounting frame 202 is fixedly connected to the rear side of the top of the base 1. A first hydraulic cylinder 203 is fixedly connected to the top of the mounting frame 202. A horizontal plate 204 is fixedly connected to the bottom end of the first hydraulic cylinder 203. Multiple sets of pressure plates 205 are fixedly connected to the bottom of the horizontal plate 204. The pressure plates 205 are arc-shaped with their openings facing downwards, which increases the contact area between the pressure plates 205 and the steel pipe and improves the pressing effect.

[0020] An auxiliary component is provided inside the pressure plate 205. The auxiliary component is used to press the steel pipe when it rotates. The auxiliary component includes a cam 5. The bottom wall of the pressure plate 205 is provided with an installation groove. The cam 5 is rotatably connected in the installation groove. A torsion spring for resetting is provided between the cam 5 and the installation groove. In the initial state, the part of the cam 5 that protrudes from the installation groove is minimal.

[0021] A hole-expanding mechanism is provided on one side of the fixing mechanism. The hole-expanding mechanism includes a mounting box 303. A hole-expanding cone 304 is installed on the side wall of the mounting box 303. The hole-expanding mechanism also includes a vertical plate 301 bolted to the top of the base 1. A second hydraulic cylinder 302 is fixedly connected to one side of the vertical plate 301. The mounting box 303 is fixedly connected to the output end of the second hydraulic cylinder 302.

[0022] A mounting plate 401 is rotatably connected to the side wall of the mounting box 303. A reaming cone 304 is threadedly connected to the side wall of the mounting plate 401. A linkage assembly is provided on the base 1. This linkage assembly is used to drive the mounting plate 401 to rotate the reaming cone 304 while the mounting box 303 drives the reaming cone 304 to move. The linkage assembly includes a rack 403 fixedly connected to the top of the base 1. A drive shaft 404 is rotatably connected between the inner walls of the mounting box 303. One end of the drive shaft 404 extends out of the mounting box 303 and is fixedly connected to a first gear 405. A gear 405 meshes with a rack 403. A drive bevel gear 406 is also fixedly connected to the drive shaft 404. A rotating shaft 407 is rotatably connected to one side of the mounting box 303. One end of the rotating shaft 407 extends into the mounting box 303 and is fixedly connected to a driven bevel gear 408. The driven bevel gear 408 meshes with the drive bevel gear 406. A second gear 409 is fixedly connected to one end of the rotating shaft 407 that extends out of the mounting box 303. A gear ring 410 is fixedly connected to the outer wall of the mounting plate 401. The gear ring 410 meshes with the second gear 409.

[0023] A support rod 402 is fixedly connected to the top of the base 1. One end of the rack 403 is fixedly connected to the side wall of the vertical plate 301, and the other end of the rack 403 is fixedly connected to the top of the support rod 402. The support rod 402 supports the end of the rack 403 away from the vertical plate 301, thereby improving the stability of the rack 403.

[0024] Working principle: In use, the steel pipe is placed in the arc-shaped groove at the top of the support base 201. The first hydraulic cylinder 203 is controlled to move the horizontal plate 204 downwards, pressing the pressure plate 205 against the steel pipe. Then, the second hydraulic cylinder 302 is controlled to move the mounting box 303 towards the end of the steel pipe, gradually inserting it into the pipe. Simultaneously, the mounting box 303 moves, driving the first gear 405 to move. The first gear 405 meshes with the rack 403, thus driving the transmission shaft 404 to rotate under the action of the rack 403. The transmission shaft 404 drives the driving bevel gear 406 to rotate, which in turn meshes with the driven bevel gear 408, thereby driving the driven bevel gear 408 to rotate the rotating shaft 407. Shaft 407 drives the second gear 409 to rotate. The second gear 409 meshes with the gear ring 410, thereby driving the gear ring 410 to drive the mounting plate 401 to rotate. This causes the mounting box 303 to drive the expanding cone 304 to move, while the mounting plate 401 drives the expanding cone 304 to rotate, reducing the friction between the expanding cone 304 and the steel pipe. At the same time, it facilitates the expansion cone 304 to enter and exit the steel pipe. When the expanding cone 304 enters the steel pipe, it will generate a certain torque in the steel pipe. When the steel pipe rotates, the steel pipe drives the cam 5 to rotate under the action of friction, making the cam 5 protrude more and increasing the pressure of the cam 5 on the steel pipe. The greater the amplitude of the steel pipe rotation, the tighter the cam 5 presses against the steel pipe, thereby preventing the steel pipe from rotating when the expanding cone 304 rotates, ensuring that the expanding cone 304 can stably enter and exit the steel pipe.

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.
