Description

Technical Field

[0001] The utility model relates to the technical field of muffler production, and more specifically, to a muffler plate punching device for automobile muffler production. Background Art

[0002] When a car engine is working, a large amount of gas will be discharged to the outside. The gas directly impacts the outside air and produces huge noise. In order to avoid noise pollution, a muffler is needed to deal with the exhaust of exhaust. The muffler will guide the internal gas so that the gas will produce sound waves that cancel each other out when flowing, thereby reducing noise. At the same time, multiple sets of holes will be opened inside to further absorb and reduce the volume.

[0003] A car muffler is provided with a silencer plate for separating spaces. When punching holes in the silencer plate, a punching device is required. The common punching device has a relatively simple structure. When punching holes, the punching rod directly contacts the silencer plate to punch holes in the silencer plate. However, the device may vibrate when it is running. Most common punching devices do not have an alignment structure. During punching, the vibration may cause the holes to shift, affecting the quality of the punching. Moreover, punching generally requires punching holes at multiple positions. Common punching devices require workers to manually adjust the position of the silencer plate, and require frequent disassembly and assembly of the fixed structure, which is not only troublesome to operate, but also easily affects the precise alignment and the quality of the punching. In addition, during punching, the flushed fragments and debris will fall onto the device. If not cleaned up in time, a large amount of accumulation may affect the placement of the silencer plate and the contact with the punching structure, affecting the impact processing.

[0048] In summary, when the overall equipment is in use (or running):

[0049] When the equipment is used, each device is supported by the workbench 1 and the work frame 2, wherein the silencer plate is marked with reference numeral 102 in the attached figure. Before punching the silencer plate 102, a suitable punching die 101 is placed on the die plate 4, and the punching die 101 is loaded into the equipment from the first mounting port 23. The punching die 101 is supported by the die plate 4 to avoid interference between the first telescopic rod 5 and the second telescopic rod 7. The first telescopic rod 5 is controlled to work so that the first telescopic rod 5 drives the first fixed plate 6 to press down. The punching die 101 is clamped and fixed by the die plate 4 and the first fixed plate 6, and then the silencer plate 1 to be processed is placed on the 102. 02 is loaded into the equipment from the second installation port 24, supported by the support plate 3, and then the second telescopic rod 7 is controlled to work, so that the second telescopic rod 7 drives the second fixed plate 8 to move, and the silencer plate 102 is clamped and fixed through the cooperation of the second fixed plate 8 and the support plate 3. When punching, the stability of the silencer plate 102 is guaranteed, and the punching die 101 will protect the silencer plate 102. If the working position of the punching equipment is inaccurate, it will be blocked by the punching die 101. The punching equipment needs to be aligned with the opening structure on the punching die 101 before it can pass through the punching die 101 and contact the silencer plate 102 to perform the punching process.

[0050] During the punching process, the mounting frame 9 provides support, and the movable frame 10 and the mounting frame cooperate to support the longitudinal motion cylinder 14. The longitudinal motion cylinder 14 works to drive the punching rod 15 to move up and down, thereby punching the silencer plate 102. During the punching process, the movable frame 10 can be controlled to move in the mounting frame 9 by controlling the first transverse motion cylinder 11 to work, and is guided by the sliding rod 25. When the movable frame 10 moves, the sliding block 26 cooperates with the sliding rod 25 to make the movable frame 10 move stably in the mounting frame 9. In addition, the second transverse motion cylinder 13 is installed on the mounting seat 27. When the movable frame 10 moves, the second transverse motion cylinder 13 moves with the sliding block 26 and the mounting seat 27. The movable frame 10 moves together with the movable frame 10, and the movement of the second lateral motion cylinder 13 is controlled. When the second lateral motion cylinder 13 is working, it contacts with the extension plate 28 to drive the extension plate 28 to move, thereby driving the mounting block 12 to move. The mounting block 12 can be controlled to move in the movable frame 10, and through the cooperation of the sliding plate 30 and the sliding groove 29, when the mounting block 12 moves, the sliding plate 30 slides along the sliding groove 29 to limit the movement of the mounting block 12, so that the mounting block 12 moves stably, so that the mounting block 12 drives the longitudinal motion cylinder 14 and the punching rod 15 to move freely in the horizontal direction. By controlling the first lateral motion cylinder 11 and the second lateral motion cylinder 13, it is convenient to punch holes at different positions of the muffler plate 102.
