Description

Technical Field

[0001] This utility model relates to the technical field of muffler processing equipment, and in particular to a bidirectional cutting device for motorcycle mufflers. Background Technology

[0002] A motorcycle muffler is a device installed at the end of the exhaust pipe of a motorcycle engine. Its main purpose is to block, reflect, interfere with and absorb the high-intensity sound wave energy generated when the engine exhausts through its complex internal structure (such as baffles, expansion chambers, sound-absorbing materials, etc.), thereby significantly reducing the intensity and harshness of exhaust noise, achieving the goals of meeting environmental protection regulations, improving riding comfort and reducing noise pollution.

[0003] A motorcycle muffler cutting device is a special tool or equipment used to process motorcycle exhaust pipes. Its core function is to mechanically cut long pipes to obtain the required length of exhaust pipe.

[0004] Based on this, Chinese patent CN102574224B discloses a pipe cutting machine. The main body of the machine comprises a cutting plate for mounting the pipe to be cut. An mounting groove is formed on the cutting plate to allow the pipe to be cut to be mounted laterally. Ball bearings are arranged at predetermined intervals on the inner surface of the mounting groove, and a pipe mounting frame is formed so that it can rotate in place when the pipe is placed in the mounting groove. A hinge shaft is mounted on the upper side of the pipe mounting frame, and a support is connected to the hinge shaft. A rotating blade mounting frame, acting as a seesaw, is mounted on the front end of the rotating blade mounting frame. A rotating blade driven by a motor is mounted on the opposite end of the rotating blade mounting frame, and a piston of a manually operated hydraulic jack is connected to the opposite end, thereby moving the rotating blade up and down. A pipe auxiliary base plate, adjustable in height, is mounted on the side of the pipe mounting frame, so that the rotating blade contacts the pipe mounted on the cutting plate, and the pipe is cut as the rotating blade rotates.

[0005] However, the aforementioned cutting equipment still suffers from technical problems such as insufficient cutting precision and efficiency. Specifically, the equipment requires operators to manually place the exhaust pipe onto the cutting device and cut it according to preset operating procedures. During the cutting process, it is necessary to maintain the stability of the cutting tool and apply force evenly to ensure the accuracy of the cutting line and the integrity of the exhaust pipe. Manual cutting of the exhaust pipe can lead to skewed or irregular cutting edges, affecting the dimensional accuracy of the finished product. To smooth the edges, further grinding and polishing are required, impacting the efficiency of batch processing. Utility Model Content

[0025] Please refer to the following: Figures 1 to 3 This utility model discloses a bidirectional cutting device for motorcycle mufflers, comprising: a base 1, a mounting frame 2, a first drive mechanism 3, a stabilizing guide frame 4, a first cutting tool 5, a supporting guide frame 6, a second cutting tool 7, and a second drive mechanism 8. The mounting frame 2 is disposed on the base 1, and the first drive mechanism 3 is disposed on the mounting frame 2. The stabilizing guide frame 4 is movably disposed on the mounting frame 2. The first drive mechanism 3 is drivenly connected to the first cutting tool 5, and the first cutting tool 5 is connected below the stabilizing guide frame 4. The supporting guide frame 6 is movably disposed on the base 1, and the second cutting tool 7 is connected to the supporting guide frame 6. The second drive mechanism 8 is disposed on the base 1, and the second drive mechanism 8 is drivenly connected to the second cutting tool 7. The second cutting tool 7 is disposed opposite to the first cutting tool 5.

[0026] Specifically, when the bidirectional cutting device for motorcycle mufflers of this invention is in operation, an external conveyor belt or other conveying mechanism transports the exhaust pipe material to be cut between the first cutting tool 5 and the second cutting tool 7. At this time, the first driving mechanism 3 drives the first cutting tool 5 downward, and the stabilizing guide frame 4 guides the downward movement of the first cutting tool 5 to ensure its smooth and accurate trajectory. Simultaneously, the second driving mechanism 8 also drives the second cutting tool 7 upward, and the supporting guide frame 6 also guides the upward movement of the second cutting tool 7, ensuring its smooth and accurate upward movement. When the first cutting tool 5 and the second cutting tool 7 move relative to each other, they can cut the exhaust pipe material simultaneously from both the upper and lower directions, resulting in a smoother and more accurate cut. Moreover, bidirectional cutting of the pipe material can be achieved with each unidirectional movement, thus effectively improving the cutting efficiency of exhaust pipe materials.

[0027] Furthermore, the first drive mechanism 3 includes a first power cylinder 301 and a first piston rod 302; the first power cylinder 301 is mounted on the mounting bracket 2, and the first power cylinder 301 is drivenly connected to the first piston rod 302. Specifically, the first power cylinder 301 can be a hydraulic cylinder or a pneumatic cylinder, with a hydraulic cylinder being preferred as it provides more stable and greater power.

[0028] Furthermore, the stabilizing guide frame 4 has a stabilizing moving block 401, a stabilizing guide rod 402, and a stabilizing guide sleeve 403; the stabilizing moving block 401 is connected below the first piston rod 302, and the first cutting tool 5 is connected below the stabilizing moving block 401; a stabilizing guide rod 402 is provided on each of the two ends of the stabilizing moving block 401, and two stabilizing guide sleeves 403 are respectively arranged opposite to each other on both sides above the mounting frame 2, and each stabilizing guide rod 402 is movably connected to a stabilizing guide sleeve 403.

[0029] Specifically, when the first power cylinder 301 is started, it can drive the first piston rod 302 to extend or shorten, so that the first piston rod 302 can drive the stabilizing moving block 401 to move downward or upward. When the stabilizing moving block 401 moves downward or upward, it can simultaneously drive the first cutting tool 5 to move downward for cutting or upward to reset. Moreover, when the stabilizing moving block 401 moves, the stabilizing guide rods 402 provided on both sides can slide from the stabilizing guide sleeves 403. The two stabilizing guide sleeves 403 are also respectively provided on both sides of the first power cylinder 301, thereby providing stable guidance and accurate guidance for the downward or upward movement of the first cutting tool 5.

[0030] Furthermore, the support guide frame 6 has a support block 601, a support guide rod 602, and a support guide sleeve 603; the support block 601 is movably disposed on the base 1, and the second cutting tool 7 is disposed on the support block 601; the two support guide rods 602 are respectively connected to the two ends of the support block 601, and the two support guide sleeves 603 are respectively disposed to the two sides of the base 1, with each support guide rod 602 being movably connected to one support guide sleeve 603.

[0031] Furthermore, the second drive mechanism 8 includes a second power cylinder 801, a second piston rod 802, an inclined reciprocating moving block 803, a moving guide rail 804, and an inclined connecting block 805; the second power cylinder 801 is connected to the base 1, and the second power cylinder 801 is drivenly connected to the second piston rod 802; one end of the second piston rod 802 is drivenly connected to the inclined reciprocating moving block 803, the moving guide rail 804 is disposed on the base 1, and the inclined reciprocating moving block 803 is movably connected to the moving guide rail 804; the inclined connecting block 805 is connected to the bottom of the support block 601, and the inclined connecting block 805 is disposed opposite to the inclined reciprocating moving block 803.

[0032] Specifically, the second power cylinder 801 can be either a hydraulic cylinder or a pneumatic cylinder. When it is started, it can drive the second piston rod 802 to extend or retract, and then the second piston rod 802 drives the inclined reciprocating block 803 to reciprocate along the guide rail 804 on the base 1. One side of the inclined reciprocating block 803 is provided with an inclined surface, and correspondingly, the inclined connecting block 805 is also provided with an inclined surface on the side corresponding to the inclined reciprocating block 803. The inclined surfaces of the two can be matched and movably connected to each other. Thus, when the inclined reciprocating block 803 feeds along the guide rail 804, it can gradually match the inclined connecting block 805 to slowly rise along the guide of the inclined structure. Thus, the inclined connecting block 805 drives the support block 601, and the support block 601 further drives the second cutting tool 5.

[0033] More specifically, the cutting edge of the second cutting tool 5 can be set to be concave so that it can better match the shape of the pipe material and avoid pipe material deviation when cutting the pipe material; in addition, the support guide rods 602 respectively provided on both sides of the support block 601 can also guide the movement of the support block 601 to be more stable and accurate when the support block 601 moves; so that the second cutting tool 7 and the first cutting tool 5 can ensure the cutting accuracy each time they move, so as to control the pipe material cutting edge to be as flat and the size accurate as possible.

[0034] In summary, the bidirectional cutting device for motorcycle mufflers of this utility model comprises a base 1, a mounting bracket 2, a first drive mechanism 3, a stabilizing guide bracket 4, a first cutting blade 5, a supporting guide bracket 6, a second cutting blade 7, and a second drive mechanism 8. The mounting bracket 2 is mounted on the base 1, and the first drive mechanism 3 is mounted on the mounting bracket 2. The stabilizing guide bracket 4 is movably mounted on the mounting bracket 2, and the first drive mechanism 3 is drivenly connected to the first cutting blade 5, which is connected below the stabilizing guide bracket 4. The supporting guide bracket 6 is movably mounted on the base 1, and the second cutting blade 7 is connected to the supporting guide bracket 6. The second drive mechanism 8 is mounted on the base 1, and the second drive mechanism 8 is drivenly connected to the second cutting blade 7, which is positioned opposite to the first cutting blade 5. When the first cutting tool 5 and the second cutting tool 7 move relative to each other simultaneously, they can cut the exhaust pipe material from both the top and bottom directions at the same time, resulting in a smoother and more accurate cut. Furthermore, each movement in the same direction achieves bidirectional cutting of the material, thus effectively improving the efficiency of exhaust pipe material cutting. Therefore, this utility model, a bidirectional cutting device for motorcycle mufflers, solves the technical problem of improving the efficiency of exhaust pipe cutting.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
