[0002] In the field of metal processing, chamfering is a common edge treatment process for removing sharp burrs at the end of a metal bar, thereby improving product safety, assembly compatibility and aesthetics. Especially for technical bars such as wire, pipe and shaft, the chamfering quality directly affects the efficiency and reliability of subsequent processing.

[0003] Existing chamfering equipment generally needs to position and rotate the metal bar, and chamfering work is performed through the mode of cutter feeding. However, such equipment usually has limitations on the length of the bar, and the clamping and rotation of long bars may face stability problems, thereby affecting the efficiency and accuracy of chamfering processing.

[0004] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a large-angle chamfering machine facilitating long metal bar processing.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0025] As shown in the figure, a large-angle chamfering machine for facilitating the processing of long metal bars includes a base 1, a fixed ring 2 on the surface of the base 1, a rotating ring 3 rotatably connected inside the fixed ring 2, a drive assembly for driving the rotating ring 3, a connecting strip 4 radially arranged inside the rotating ring 3, two sliding blocks 5 slidably connected on the connecting strip 4, a chamfering cutter head 6 rotatably connected to one side surface of each of the two sliding blocks 5, a first motor 7 for driving the chamfering cutter head 6 on the other side surface, and a control assembly for controlling the relative movement of the two sliding blocks 5.

[0026] The drive assembly includes a second motor 8 disposed on one side of the base 1, the output shaft of the second motor 8 is provided with a first gear 9, and the rotating ring 3 is provided with an internal gear 10 meshing with the first gear 9 along its circumferential inner wall.

[0027] Before chamfering, the metal bar to be chamfered is installed and positioned, with its end placed between two chamfering cutters 6. The first motor 7 drives the two chamfering cutters 6 to rotate, while the drive assembly drives the rotating ring 3 to rotate. According to the actual chamfering requirements, the control assembly drives the two sliding blocks 5 to move relative to each other, so that the two chamfering cutters 6 gradually move closer. This can improve the chamfering efficiency of longer metal bars and also facilitate the control of the degree of chamfering on the metal bar.

[0028] The control assembly includes two semi-circular guide plates 11 disposed within the rotating ring 3. The surfaces of the two guide plates 11 are provided with centrally symmetrical and spirally arranged guide grooves 12. The distance between the inner wall of the guide groove 12 and the center of the rotating ring 3 gradually decreases. Connecting blocks 13 are fixedly connected to the back of the two guide plates 11. A fixing plate 14 is fixedly connected between the two connecting blocks 13. A rotating shaft 15 is rotatably connected to the fixing plate 14 at the center of the connecting bar 4. The assembly also includes a driving component for driving the rotating shaft 15. During the rotation of the connecting bar 4, two sliding blocks 5 abut against the inner walls of the two guide grooves 12 respectively.

[0029] When chamfering is being performed, if it is necessary to shorten the distance between the two chamfering cutter heads 6, the drive unit drives the rotating shaft to rotate the connecting bar 4. When the connecting bar 4 rotates, under the action of the guide plate 11 and the guide groove 12, the distance between the two sliding blocks 5 and the rotating shaft 15 is shortened. This allows the two chamfering cutter heads 6 to gradually approach each other during chamfering to achieve progressive chamfering and ensure the smooth progress of the chamfering work.

[0030] The driving component includes a third motor 16 disposed on the back of the fixed plate 14, the output shaft of which passes through the fixed plate 14 and is provided with a second gear 17, and a third gear 18 meshing with the second gear 17 is disposed on the rotating shaft 15.

[0031] The connecting strip 4 has two opposing sliding grooves 19 on both sides of the rotating shaft 15 along its length. The sliding block 5 is slidably connected in the sliding groove 19. The inner wall of the two sliding grooves 19 near the end of the rotating shaft 15 is provided with a limiting sleeve 20. The opposite side of the two sliding blocks 5 is provided with a limiting rod 21 slidably connected in the limiting sleeve 20. A spring 22 is fixedly connected between the end of the limiting rod 21 and the inner wall of the end of the limiting sleeve 20.

[0032] When the connecting bar 4 rotates, it drives the two sliding blocks 5 to move relative to each other under the action of the guide plate 11. This causes the limiting rod 21 to slide inside the limiting sleeve 20, which compresses the spring 22. After the chamfering is completed, when the driving component drives the connecting bar 4 to rotate in the opposite direction to reset, the two sliding blocks 5 reset under the action of the spring force of the spring 22, which facilitates the subsequent chamfering process.

[0033] The connecting strip 4 has a limiting groove 23 that runs through its end and the upper and lower side walls at the two sliding grooves 19. The guide plate 11 is slidably connected in the limiting groove 23. The upper and lower surfaces of the two sliding blocks 5 and the side surface away from the rotating shaft 15 are provided with a limiting plate 24 with an arc-shaped end face. The limiting plate 24 slides in the limiting groove 23, so that the limiting plate 24 always abuts against the inner wall of the guide groove 12, ensuring its stability during chamfering.

[0034] The sliding block 5 extends out of the sliding groove 19 on both sides and is provided with abutting plates 25 that abut against the surface of the connecting strip 4 to ensure the stability of the sliding block 5 sliding in the sliding groove 19.

[0035] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
